Background technology
In the equipment such as integrated treatment of the dense place of the manufacturing of some fresh water, solution, waste water, often need solution heating evaporation with low concentration, in order to the moisture in the solution from coming out, and then obtain the solution of high concentration or pure water.For example the alkali lye of employed high concentration becomes the spent lye of low concentration after being used to complete in dyeing process, for spent lye all is that the mode that adopts dealkalize to purify the back discharging is handled traditionally, such processing mode not only causes the waste at raw material, and still can cause the pollution of environment.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of rational in infrastructure, energy utilization rate is high, evaporation and the good flash-boiling evaporators of concentrated effect.
Flash-boiling evaporators of the present utility model includes the multistage evaporation condensing unit, and the bottom of evaporative condenser unit is a vaporization chamber, is connected in series successively by choke valve between the vaporization chamber of evaporative condensers at different levels unit; The top of evaporative condenser unit is condensation chamber, the condensation-water drain that the condensate draining of condensation chamber bottom connects step by step and finally leads to the outside in the setting of place, first order evaporative condenser unit; Outer setting in the evaporative condenser unit has the solution feed pump that is used for extracting pending weak solution, and the drain pipe of solution feed pump passes in the vaporization chamber of first order evaporative condenser unit; The vaporization chamber of first order evaporative condenser unit is provided with the taphole that leads to first circulating pump, the drain pipe of first circulating pump enters a heater after passing the condensation chamber of part or all of evaporative condenser unit, and the drain pipe of heater feeds the vaporization chamber of afterbody evaporative condenser unit; Communicating of first order evaporative condenser unit with outside negative pressure environment.
Described heater is a steam heater.
First order evaporative condenser unit communicates with outside negative pressure environment by condensation-water drain, and described outside negative pressure environment is a condensed water collecting chamber, and the outlet pipe of condensed water collecting chamber bottom leads to a condensation water tank through the condensed water collecting pump; The upper opening of condensed water collecting chamber communicates with a condensed water playpipe, the jet of condensed water playpipe lower end is aimed at the condensation water tank of below, the condensed water outlet pipe of condensation water tank leads to the inlet of condensed water playpipe upper end through a condensed water circulating pump, the injection that circulates by condensed water forms negative pressure in the condensed water collecting chamber.
The utility model by hot solution in evaporation cavity step by step decompression and expansion realize the evaporation of moisture content, make the steam that rises to the condensation chamber from vaporization chamber carry out heat exchange with the pipeline of carrying cold soln, utilize steam waste heat that the solution that does not enter heater is carried out preheating on the one hand, utilize cold soln to make the steaming condensation on the other hand as cooling medium, thereby improved the utilization ratio of heat energy greatly, guaranteed evaporation and concentrated effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The each several part mark is as follows in the accompanying drawing: evaporative condenser unit 01, vaporization chamber 011, condensation chamber 012, condensate draining 013, condensation-water drain 014, choke valve 015, solution feed pump 02, first circulating pump 03, the drain pipe 031 of first circulating pump, heater 04, condensed water collecting chamber 05, condensed water collecting pump 06, condensation water tank 07, condensed water playpipe 08, jet 081, condensed water circulating pump 09.
As shown in the figure, this flash-boiling evaporators includes multistage evaporation condensing unit 01, and the bottom of evaporative condenser unit is a vaporization chamber 011, is connected in series successively by choke valve between the vaporization chamber 011 of evaporative condensers at different levels unit; The top of evaporative condenser unit is condensation chamber 012, and condensate draining 013 is arranged at the condensation chamber bottom; Outer setting in the evaporative condenser unit has the heater 04 that is used for extracting the solution feed pump 02 of pending weak solution and is used for heated solution; First order evaporative condenser unit communicates with subnormal ambient.
In the course of work, solution feed pump is delivered to weak solution in the vaporization chamber 011 of first order evaporative condenser unit.The weak solution of being sent by first order vaporization chamber enters first circulating pump 03, the drain pipe 031 of first circulating pump enters its condensation chamber from third level evaporative condenser unit, and enter heater 04 (steam heater) after passing third level condensation chamber condensation chambers at different levels afterwards successively, enter its vaporization chamber through the solution after the heater heating from afterbody evaporative condenser unit, in the vaporization chambers at different levels before entering step by step by the choke valve between each vaporization chamber again, in this process, because vaporization chamber 011 pressure reduces step by step, so solution has a decompression and expansion evaporating course step by step.The steam that vaporization chamber 011 evaporation produces rises and enters the condensation chamber 012 on top, and steam carries out heat exchange with the pipeline of carrying cold soln and is condensed in condensation chamber, and condensed water compiles in condensate draining 013 and sent by condensation-water drain 014.
