Abstract
The utility model provides an ammonia recovery system for dyeing and weaving, which comprises a first absorbing tower, a second absorbing tower and a third absorbing tower. The lower end of the first absorbing tower is provided with a mixed gas inlet and an ammonia water drain outlet, the lower ends of both the second absorbing tower and the third absorbing tower are provided with a waste gas duct communicated with the former-stage absorbing tower, an exhaust fan is arranged at the tail end of the waste gas duct communicated with the third absorbing tower, the lower end of the second absorbing tower is provided with a water inlet and an ammonia duct unidirectionally communicated with the first absorbing tower, and the upper end of the third absorbing tower is provided with a waste gas drain outlet, while the lower end is provided with a softened water inlet and a wastewater drain outlet. The system is characterized in that the wastewater drain outlet of the third absorbing tower is connected with the water inlet at the lower end of the second absorbing tower through the ammonia water duct, the waste gas drain outlet of the third absorbing tower is communicated with the waste gas duct of the third absorbing tower through a duct provided with an automatic adjusting valve, and connection position of the duct and the waste gas duct is arranged at an inlet end of the exhaust fan. The system reduces atmospheric pollution and water pollution, saves water and sulfuric acid, and has excellent working performance.
Description
Technical field
The utility model provides a kind of dyeing and weaving ammonia recovery system, belongs to dyeing and weaving and uses the energy-conserving and emission-cutting technology field.
Background technology
The absorption tower of textile printing and dyeing industry use now generally is to be made of two groups of absorption towers and one group of scrubbing tower, its effect is that the liquefied ammonia processing machine is directly reclaimed halfway waste gas (mist that comprises water vapour, air, ammonia), by exhaust blower be extracted into that the absorption tower is carried out once, secondary absorbs, in this process, ammonia is absorbed in the water, for the secondary absorption tower is nonabsorbable will be through scrubbing tower, add the sulfuric acid neutralization then and drain when waste water.
There is following shortcoming on such absorption tower at present: (1) two group of absorption tower is thorough inadequately for the absorption of waste gas, causes a large amount of waste gas, wherein also comprises ammonia, enters in the atmosphere environment is polluted; (2) scrubbing tower in persulfuric acid and after the waste water of discharge also environment is polluted; (3) owing to waste gas, waste water are directly drained, cause the waste of ammonia and water;
The utility model content
The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, dyeing and weaving ammonia recovery system that serviceability is good.Its technology contents is:
Comprise the absorption tower No. one, No. two absorption towers and No. three absorption towers, wherein the lower end on an absorption tower is provided with mist inlet and ammoniacal liquor floss hole, the lower end on No. two absorption towers and No. three absorption towers is equipped with the exhaust piping that is communicated with the upper level absorption tower, air exhauster is located at the end of the exhaust piping that is communicated with No. three absorption towers, lower end, No. two absorption towers is provided with water inlet and the unidirectional ammoniacal liquor pipeline that leads to an absorption tower, the upper end on No. three absorption towers is provided with Waste gas outlet, the lower end is provided with demineralized water inlet and discharge of wastewater mouth, it is characterized in that: the discharge of wastewater mouth on No. three absorption towers connects the water inlet of lower end, No. two absorption towers through the ammoniacal liquor pipeline, the pipeline of the Waste gas outlet on No. three absorption towers through being provided with automatic regulating valve be the exhaust piping on logical No. three absorption towers in succession, and the junction of pipeline and exhaust piping is positioned at the arrival end of air exhauster.
The utility model compared with prior art, its advantage is:
1, giving No. two absorption tower moisturizings by the low concentration ammoniacal liquor in No. three absorption towers, is No. three absorption tower moisturizings with demineralized water, has save in being input in No. three absorption towers the sulfuric acid with ammoniacal liquor, has saved demineralized water and sulfuric acid, has reduced cost;
2, the pipeline of the Waste gas outlet on No. three absorption towers through being provided with automatic regulating valve leads to the exhaust piping on No. three absorption towers in succession, to not handle completely waste gas enters once more in No. three absorption towers and handles, the rate of recovery of ammonia in the waste gas that has improved, having reduced atmosphere pollution and water pollutes, and scrap build drops into low, easy for operation, can not cause damage to the original equipment main body.
