Description

Purification treatment method for waste gas in textile printing and dyeing production

Technical Field

The invention relates to the technical field of waste gas treatment, in particular to a waste gas purification treatment device and a waste gas purification treatment method for textile printing and dyeing production.

Background

Printing and dyeing is also called dyeing and finishing. Is a processing mode and is also a general term for pretreatment, dyeing, printing, after finishing, washing and the like; the dyeing and finishing specialty of the department is incorporated into the light chemical engineering specialty; as early as six or seven thousand years ago, our ancestors were able to dye burlap red with hematite powder. The original tribe living in the Nuomu flood area of Qinghai Chaida basin can dye the wool into yellow, red, brown, blue and other colors to weave the wool cloth with color stripes. The staining technique is continuously improved during the week period. The palace manual workshop is provided with a professional chihuili 'dyer' to 'palm dye grass', and manages the dyeing production. The color developed is also increasing. By the han generation, staining techniques reached a fairly high level.

Use large-scale machine to replace the manpower to carry out weaving printing and dyeing in modern weaving printing and dyeing production process generally, but can produce a large amount of waste gases in modern course of working, if direct with these waste gas emission then can cause the serious pollution of environment in the air, so need the purification unit of a waste gas to discharge in the air after handling waste gas again, current exhaust purification unit generally is to cool down waste gas after to it carry out filtration treatment again to discharge in the air, but this kind of waste gas generally contains more heat, if directly cool down to it again purify after handling then can cause the waste of heat in the waste gas, can not utilize the heat.

Present exhaust gas purification device generally can be provided with spray set and spray waste gas, spray set among the prior art exhaust gas purification device generally is provided with the shower nozzle in the bottom of water tank and has the spray box to let in the spray box through waste gas when spraying the operation in the bottom mounting of water tank, the shower nozzle of accessible water tank bottom sprays waste gas this moment and handles, but the shower nozzle of this kind of device generally all fixes so can't carry out intensive mixing and then the dust removal processing to the waste gas that sprays incasement portion on the top of spray box, cause the relatively poor phenomenon of spraying effect.

Meanwhile, after the exhaust gas purification treatment is finished, the treated exhaust gas needs to be discharged, in the prior art, a straight pipe and an exhaust fan are generally arranged to discharge the treated exhaust gas, but the treated exhaust gas can contact with an inner cavity of an exhaust pipe when being discharged, so that sundries in the inner cavity of the exhaust pipe can be correspondingly taken out in the discharging process, further pollution of the discharged exhaust gas is caused, the discharge standard is reduced, and the discharge efficiency is influenced.
