Abstract
The utility model relates to a horizontal tubular primary cooler scale removal device, including high-pressure aqueous ammonia spray set and adjusting valve, high-pressure aqueous ammonia spray set and adjusting valve install respectively at the circulation aqueous ammonia shower entrance of primary cooler. The device simple structure, convenient operation, the effectual phenomenon that prevents the primary cooler scale deposit has prolonged the life of primary cooler.
Description
Technical field
The utility model relates to a kind of cleaning device, particularly relates to a kind of transverse tube type primary cooler apparatus for eliminating sludge.
Background technology
Primary cooler is the visual plant of coal chemical enterprise coal-gas recovering cleaning procedure, and it mainly is responsible for the cooling of coke-stove gas, is beneficial to carry with air blast.Transverse pipe initial cooler is a kind of high-effective gas cooling device newly developed, and it is compared with original commonly used vertical tube primary cooler, and to have a film-cooled heat big, the heat exchange efficiency advantages of higher.In the actual production running, the phenomenon that primary cooler exists resistance to increase after operation a period of time has influenced the normal operation of producing, and can cause coke-stove gas to diffuse when serious, has not only wasted valuable resource, and has polluted environment.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of simple in structure, easy to operate a kind of transverse tube type primary cooler apparatus for eliminating sludge is provided.
In order to address the above problem, the utility model by the following technical solutions:
A kind of transverse tube type primary cooler apparatus for eliminating sludge comprises high pressure aqua ammonia spray equipment and control valve, and high pressure aqua ammonia spray equipment and control valve are installed in the cyclic ammonia water shower porch of primary cooler respectively.
Described high pressure aqua ammonia spray equipment is made up of high pressure aqua ammonia pipeline and shower nozzle, and shower nozzle is installed in high pressure aqua ammonia pipeline front end.
Compared with prior art, the beneficial effects of the utility model are:
The utility model apparatus structure is simple, and easy operating and maintenance purge the separate unit primary cooler by adopting high pressure aqua ammonia, have effectively prevented the phenomenon of primary cooler fouling, have solved the problem that the primary cooler resistance increases.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The groundwork principle of transverse pipe initial cooler is as follows: coal gas enters from transverse pipe initial cooler top, divides three sections coolings.Epimere cools off coal gas with remaining hot water winter, and all the other times, with 32 ℃ of recirculated waters, hypomere was cooled to 21～22 ℃ with 16 ℃ of chilled water with coal gas with the stage casing.For the cooling that guarantees primary cooler removes the naphthalene effect, spray tar, ammonia water mixture continuously at upper and lower section, spray with hot ammoniacal liquor circulation at its top, with impurity such as the tar on the removing tube wall, naphthalenes.On the primary cooler, the stage casing condensate liquid of discharging flows into epimere condensation liquid bath through water sealed tank, with pump it sent into the circulation of primary cooler epimere middle part and sprays, unnecessary part is delivered to mechanical settling tank.The condensate liquid that the primary cooler hypomere is discharged flows into hypomere condensation liquid bath through water sealed tank, with pump it is sent into the circulation of primary cooler hypomere top and sprays, and redundance flows into epimere condensation liquid bath.
A kind of transverse tube type primary cooler apparatus for eliminating sludge as shown in Figure 1, comprises high pressure aqua ammonia spray equipment 1 and control valve 2, and high pressure aqua ammonia spray equipment 1 is made up of high pressure aqua ammonia pipeline and shower nozzle, and shower nozzle is installed in high pressure aqua ammonia pipeline front end.High pressure aqua ammonia pipeline and control valve 2 are installed in the cyclic ammonia water shower porch of primary cooler respectively.Handover operation when control valve 2 is used to clean primary cooler.
Operating process of the present utility model is:
1) in many transverse pipe initial cooler uses of using in parallel, the separate unit primary cooler is cleaned with hot ammoniacal liquor.
2) cyclic ammonia water porch valve is closed in cleaning, opens high pressure aqua ammonia inlet control valve 2.
3) in the cleaning process, control the gas outlet temperature of transverse pipe initial cooler to be cleaned, make it be not more than 35 ℃.
4) the cleaning time was controlled at 30～40 minutes.
5) control valve 2 that after cleaning finishes high pressure aqua ammonia entered the mouth is closed ON cycle ammonia inlet valve.
Claims (2)
1. a transverse tube type primary cooler apparatus for eliminating sludge is characterized in that, comprises high pressure aqua ammonia spray equipment and control valve, and high pressure aqua ammonia spray equipment and control valve are installed in the cyclic ammonia water shower porch of primary cooler respectively.
2. a kind of transverse tube type primary cooler apparatus for eliminating sludge according to claim 1 is characterized in that described high pressure aqua ammonia spray equipment is made up of high pressure aqua ammonia pipeline and shower nozzle, and shower nozzle is installed in high pressure aqua ammonia pipeline front end.
