Description

The utility model relates to energy, can be used in the maintenance and repair of heating systems of buildings and structures, hot and cold water supply systems, heat exchangers and boilers.

The main objective of the utility model is the cleaning of deposits on the internal surfaces of pipelines, heat exchangers, boilers.

The deposits have a complex composition and have low thermal conductivity. If measures are not taken to clean and restore the systems (restoration of the original internal section of pipelines, heat exchangers), the heating system becomes completely clogged, which leads to the cessation of the circulation of the heating medium inside the system. As a result, there is a need for major repairs, or replacement of heating systems, heat exchangers, boilers. Currently, a complete replacement of heating systems, heat exchangers is an expensive and lengthy procedure. Permanent scheduled cleaning of systems with special plants using chemical reagents is required.

The washing device allows washing pipes of the heating system of the heat exchangers of the boilers without dismantling and incorporating it into the circulation circuit of the installation.

The authors were faced with the task of creating a washing installation for cleaning water heating systems, heat exchangers and boilers from deposits on internal surfaces using new design solutions and new modern environmentally friendly chemicals that do not destroy the structural material of the washed systems.

The closest analogue to the claimed and technical solution is the utility model Ru 22758 U1 B08B 9/02, which describes “Mobile installation for flushing heating and water supply systems.

However, the known device has disadvantages in design:

- the installation is very bulky, saturated with a large number of devices and nodes;

- its transportation in a vehicle is very problematic;

- high energy consumption;

- traditional acids are used as the main washing reagents, which aggressively affect the structural material of the washed systems; neutralization of chemical reagents is required.

The purpose of the claimed utility model is to expand the functionality by increasing the efficiency of the design of the washing device.

The flushing device includes:

1 - tank, 2 - sunroof, 3 - level indicator, 4 - level gauge, 5 - protective cone, 6 - reverse cone, 7 - grid, 8 - tangential tap, 9 - tank tap,

10 - reverse, 11 - mains pump, 12 - circular pump, 13 - dirt trap, 14 - dirt trap outlet, 15 - diopter screw control, 16 - check valve, 17 - suction pipe, 18 - discharge pipe, 19 - return pipe, 20 - bypass, 21 - suction pipe of the circulation pump, 22 - discharge pipe of the circulation pump, 23 - electric control panel, 24 - heat source, 25-27 pressure gauges, 28 - compressor, 29 - control valve, 30-44 ball valves, 45 - contact thermometer, 46-53 flexible pressure hoses, 54 - heat supply pipe Yeti, 55 - return pipe of the heating network, 56 - water source, 1 reverse input, 1 reverse output, 2 reverse output, 3 reverse output.

The flushing device operates as follows:

The first circulation circuit (open mode). From the water source 56, water enters the flexible pressure hose 48, the open ball valve 35, then enters the return pipe 19 through the open ball valve 34, the tangential branch 8 tank 1 is filled with water. The hatch 2 in this position is open, the filling of the tank 1 is controlled by a level 3 indicator in the level gauge 4, after filling the tank 1 with water, the ball valve 35 is closed, then the ball valve 37 is gradually opened on the suction pipe 17 of the installation, through the dirt trap 13, then through the suction pipe 17 to the network pump 11. On the electric control panel 23, press the "start" button, the pump 11 is turned on, then on the discharge pipe 18 we gradually open the ball valve 40, and water enters the network pump, then after the pump 11 water p steps into the discharge pipe 18, open the control valve 29, through the check valve 16, then to the reverse 10, open the ball valve 30. 2 exit of the reverse 10, through the flexible pressure sleeve 52, into the return pipe 55 of the heating system, then through the flushed object, the supply pipe heat network 54, through a flexible pressure sleeve 53, to the 3 outlet of the reverse 10, through the open ball valve 32, through the 1 outlet of the reverse 10, with the ball valve 35 closed, through the open ball valve 34, the return pipe 19, through the tangential branch 8 water enters into the tank 1. Come out of the water of the tangential outlet 8 at a high speed along the walls

tank 1 and moves in a spiral. This effect can be used to dissolve bulk chemicals poured in the center of the cone 6 in the tank 1 on the grid 7.

Water flows through the net to the bottom of the tank 1. A protective cone 5 is installed above the suction pipe 17 to protect the suction pipe 17 from washed large and small particles of deposits (calcium, magnesium, glandular, etc.). In order to prevent dirt from entering the suction pipe 17 and then into the pumps 11 and 12, the discharge of water from the tank 1 is periodically checked: the ball valve 38 opens, through the outlet of the tank 9 and the flexible pressure sleeve 46, the discharge. Water is fed to the flushed system by periodically opening the ball valve 35, with the pump 11 turned off and the ball valve 32 closed.

An automatic air purifier (not shown in the diagram) is used to discharge air from the flushed system. In the case when the automatic air vent does not have time to discharge the air, due to the supply of incoming water, the air will be displaced through the supply pipe of the heating network 54, through the flexible pressure hose 53, through the lower outlet of the reverse, an open ball valve 32 on the reverse 10, water enters the return pipe 19 , through an open ball valve 34, a tangential branch 8, into the tank 1. At the same time, water is recharged with an open ball valve 35.

When filling the flushed system, the level in the tank 1, the level 3 indicator should be in the upper part of the level gauge 4, the level is regulated by opening and closing the ball valve 35.

Filling the system with water is carried out by the network pump 11 to the permitted pressure specifically for each system. We wash the heating system due to water circulation by the network pump 11 and reverse operation 10, washing the primary loose layer of deposits on the walls of pipelines 54, 55 and heating devices (not shown in the diagram).

The operation mode of the reverse 10 is changed, but we leave tank 1 in the circulation system, in the atmospheric mode, on the reverse 10, close the ball valves 30 and 32, open the ball valves 31 and 33. We set the temporary operation mode in this position for 3-5 minutes (cycle), then we change the direction of water movement

on roar 10, for this we close the ball valves 31 and 33, open the ball valves 30 and 32, in this position we also circulate for 3-5 minutes, etc.

Accumulated deposits from flushing the system are discharged into the sewer from tank 1, through branch 9, ball valve 38, pressure flexible sleeve 46, and also from the dirt collector 13, through branch 14, ball valve 39 and flexible pressure sleeve 47. We make the system water-filled, by opening the ball valve 35.

On the device’s discharge pipe 18 we close the control valve 29. Water (water chemical solution) will move through the open lower outlet of the discharge pipe 18, flexible pressure hose 51, to the heat source 24, turn on the heat source by pressing the “start” button on the electric control panel 23 .Water passing through a heat source is heated to a predetermined temperature. Heated water flows from the heat source through the flexible pressure hose 50 to the upper inlet of the discharge pipe 18. After the required water temperature is established in the entire flushed system, a chemical reagent is added (filled, filled). The chemical reagent is loaded through an open hatch 2 onto the grid 7 of the cone 6 (in the case of a liquid reagent, it is poured directly into the tank 1), the heated water coming in a spiral from the tangential branch 8 dissolves the chemical reagent. The amount and type of added chemical reagent is calculated from:

- sediment composition (express analysis);

- the ratio of sediment content in the flushed system to the total volume of the system.

The temperature of the wash solution is controlled by a contact thermometer 45.

After a complete circulation cycle with the added chemical in the system being washed, we perform a reversal (changing the direction of movement of the washing solution), for this we close the ball valves 30 and 32 and open the ball valves 31 and 33. Set the time

the operating mode in this position is 3-5 minutes (cycle), then we change the direction of water movement on reverse 10, for this we close the ball valves 31 and 33, open the ball valves 30 and 32, in this position we also circulate for 3-5 minutes etc.

Next, smoothly cover the ball valve 34 on the return pipe 19, dump the residual air from the flushed system. After that, add the required amount of make-up water using a ball valve 35. The heat source continues to work to maintain the required temperature of the wash solution.

Second circulation circuit (closed mode).

From the "open mode" of the device, go to the "closed mode". We close the ball valve 34 on the return pipe 19 and close the ball valve 37 on the suction pipe 17, open the ball valve 36 on the bypass 20, gradually close the ball valve on the suction pipe 17, press the “stop” button on the electrical control panel 23 of the network pump 11, withdraw from work, the network pump 11, then on the electric control panel 23, press the "start" button and start the circulation pump 12, smoothly open the ball valve 41 on the suction pipe 21 of the circulation pump 12 and into the discharge t uboprovod device 18 is translated in the "closed mode". Further up to the open control valve 29, through the non-return valve 16, through the open ball valve 30 on the reverse 10, 2, the reverse outlet, through the flexible pressure hose 52 to the return pipe 55 of the heating system, then through the flushed object, the supply pipe of the heating network 54, through the flexible pressure hose 53 to 3 exit of reverse 10, through open ball valve 32 through 1 exit of reverse 10 with closed ball valve 35 at bypass 20, through a diopter nut control 15, dirt collector 13, discharge of dirt collector 14, designed to discharge washed sewage into the sewer live through ball valve 39 and pressure flexible sleeve 47.

We change the operating mode of the reverse 10, close the ball valves 30 and 32, open the ball valves 31 and 33. Set the temporary operation mode in this position for 3-5 minutes (cycle), then change the direction of water movement

on the reverse 10, for this we close the ball valves 31 and 33, open the ball valves 30 and 32, in this position we also circulate for 3-5 minutes, etc. This cycle is repeated many times throughout the wash.

In the closed mode of operation of the device, water is fed by periodically opening the ball valve 35.

The quality control of the circulating chemical solution (water) is carried out visually using a control diopter nut 15.

We periodically discharge sediment from the tank 1 and dirt trap 13 (described above).

The quality control of the circulating water is evaluated visually using a diopter screw control 15, and an express analysis of the washing solution is periodically performed. After the chemical agent is completely stopped, the heating of the washing solution stops, by pressing the stop button on the electric control panel 23 we turn off the heat source 24. Close the ball valve 42 at the lower outlet of the discharge pipe 18 and close the ball valve 43, at the upper entrance to the discharge pipe 18 and open the control valve 29 on the discharge pipe 18 of the installation.

After flushing, we prepare the flushing device and the flushed system to discharge the spent chemical reagent.

We gradually block the ball valves 41 on the circulation pump 12 and on the electric control panel of the circulation pump 23, press the stop button and take the circulation pump 12 out of operation. On the reverse 10, close the ball valves 30, 32, 33, the ball valve 31 is open.

We drain from the washed system the spent washing solution of the chemical reagent under its static pressure from the system through the dirt collector 13, branch 14, open ball valve 39, a flexible pressure head 47 discharge. We reset from the system 1 / 3-1 / 4 of the volume of the system. Close the ball valve 39.

For faster discharge of the spent reagent from the heating system, we turn on the air compressor 28, compressed air from the compressor receiver enters through a flexible pressure hose 49, through

open ball valve 44, into the discharge pipe 18. On the reverse 10, leave the ball valve 33 open and the ball valves 30, 31, 32 closed, the air at the lower outlet of the reverse 10 enters through the flexible pressure hose 53, into the supply pipe 54 of the heating network.

We raise the pressure in the flushed network due to compressed air to the permitted pressure for this network (system).

The air is under pressure in the upper part of the system, presses on the remaining volume of water, using this, we discharge through the return pipe of the heat network 55 and the flexible pressure hose 52, through 2 the output of the reverse 10, the open ball valve of the reverse 31, through the return pipe 19, at open ball valve 36 on the bypass 20, through the dirt trap 13, the discharge of the dirt trap 14 open the ball valve 39, through a flexible pressure sleeve 47 discharge into the sewer. As the water decreases from the system, periodically close the ball valve 39 and maintain the pressure in a given mode.

This method of removing water (solution, coolant) from the system is much more effective than the natural discharge method, pressure drainage is faster, existing stagnant zones are blown where residues of washed deposits can accumulate.

The remainder of the reagent solution is discharged into the sewer from the tank 1 through the outlet 9, ball valve 38, a flexible discharge hose 46 discharge.
