Description

The invention relates to gas cleaning technology and can be used to clean high-temperature gases containing fine dust, in particular for the final cleaning of gases before they are released into the atmosphere.

The purpose of the invention is to reduce operating costs.

FIG. 1 shows a condensation dust collector, a general view; FIG. 2 - section A-A on fit 1; in fig. 3 - section bb in Fig.2; FIG. 4 is a section B-B in FIG. 3: FIG. 5 is a section of YYD in FIG. 3; in fig. 6 - irrigation tube assembly with gutter, axonometric.

Condensation dust collector contains a cylindrical body 1 with a tangential g, chtrubkom 2, pipe 3 for

supplying a cooling agent to shirt A The case has a conical sludge collector 5 from the bottom, and a droplet separator 6 with an exhaust window 7 and a hatch 8 on top. The shirt 4 of the housing 1 consists of an outer 9 and an inner wall 10 interconnected tightly. F wall 9 is connected to the nozzle 3 of the cooling agent. Tubes 1 1 of the OP system are folded to the inner walls with holes 12. At the free ends of the tubes 11, loops 13 are welded at the same time as the plugs of the tubes 11. At the inner wall 10 of the housing 1, protective covers L are attached to the free ends tubes 11 installed partition 15, and between the plates 14 and the partition 15 on each tube 11 counter to the gas flow installed removable

the chute 16, as a result of which a flow channel 17 is formed between the plates 14 and the partition 15.

The partition 15 is made of individual sheets 18, one vertical edge 19 of each sheet 18 is bent toward the flow channel 17 in the form of an Archimedes spiral. The yakladki 14 and the sheets 18 have holes and freely fit over the tubes 11. The fastening of the pads 14, the grooves 16 and the sheets 18 is made by a wedge-type lock 20 in the loop 13.

On the working inner surface of the collection of 5 sludge laid lining.

Condensation dust collector works as follows.

Through the tangential nozzle 2, the dust-gas-gas mixture from the boiler unit with a temperature of + 140 ° C at a speed of 15 m / s enters channel 17. When moving through the channel 17, the centrifugal force is pressed against the plates 14, captures from the tubes 11 through the openings 12 drops of water from the jacket 4, which leads to cooling of solid dust particles and their precipitation in the form of condensate on the surfaces of the plates 14. The flow through the channel 17 provides twist in a spiral, followed by vacuum at the exit of the channel. Subsequent movement of the flow occurs on the back side of the partition 15. The speed and temperature in this zone are reduced, respectively, to 5-6 m / s and 100-110 ° C. At the same time, the gas stream is maximally saturated with water vapor and has a minimum of solid dust particles. Having a difference of speeds and, accordingly, pressures on both sides of the partition 15, a part of the cooled gas flow is captured through the gaps of the bent edges 19 of the sheets 18 and enters again into the channel 17,

Thus, water vapor enters a subsequent turn in the channel. The purified gas stream rises into the drip catcher 6, where additional precipitation of moisture occurs, and then exits into the atmosphere through the outlet port 7.

The precipitated sludge flows down the dust collector stacks into the sludge collector 5 and is removed for filtration. For the production of repair and maintenance works

hatch 8 in the drift catcher, through which access is free for people to carry out repairs.

The presence of pads provides protection from premature wear of the cylindrical part of the body and the conical collection.

The use of linings attached to the irrigation tubes through removable troughs allows replacement in the case of

wear with minimal labor costs, makes it possible to rearrange worn linings in the zone with the least wear.

The implementation of the partition of the individual

sheets, one vertical edge of which is bent into the interior of the channel, allows for additional saturation of gases in the channel with water vapor from the central part, which increases the degree of cleaning and reduces the consumption of cooling agent, while it becomes possible to change individual sheets.
