Embodiment Construction

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] There are many treatment methods for waste gas containing hydrogen sulfide. The treatment method disclosed in the present invention is to collide the waste gas containing lye and hydrogen sulfide with high-pressure impact technology, and absorb the lye to absorb the hydrogen sulfide in the waste gas.

[0015] see attached figure 1 , the device disclosed in the present invention for treating hydrogen sulfide in waste gas using impinging flow technology includes an absorption tower and a lye circulation tank. The top of the absorption tower 8 is provided with an exhaust port 9 , and the bottom of the first-stage absorption tower 6 arranged at the lower part is connected with the intake main pipe 1 . Each absorption tower is respectively provided with an air inlet pipe 3, an alkali inlet pipe 10 and an alkali discharge pipe 13. The intake pipes 3 are respectively p...

Abstract

Provided is a processing method of production waste gas containing hydrogen sulfide. The processing method includes adopting impinging stream technology to conduct high pressure collision on absorbing alkali liquid and waste gas containing hydrogen sulfide and enabling the absorbing alkali liquid to absorb and process hydrogen sulfide in the waste gas. Two absorption towers are connected in series vertically, and the insides of the two absorption towers are communicated. A gas inlet pipe, an alkali inlet pipe and an alkali outlet pipe are arranged in each absorption tower. A gas inlet branch pipe communicated with the gas inlet pipe is arranged on each gas inlet pipe, and a high pressure nozzle is installed in each gas inlet branch pipe port. Each alkali inlet pipe is connected with the corresponding high pressure nozzle through a corresponding alkali inlet branch pipe, and the alkali inlet pipe is connected with the bottoms of the absorption towers. Each alkali inlet pipe and each alkali discharge pipe are respectively connected with an alkali liquid circulation tank, and a centrifugal pump is arranged between the alkali inlet pipe and the alkali liquid circulation tank. A waste gas processing device adopts the impinging stream technology to improve absorption rate of hydrogen sulfide, and is good in waste gas processing effect. The absorption towers are low in resistance, and sodium bisulfide produced in the reaction is high in density.

Description

technical field [0001] The invention relates to a processing device and a processing method for production waste gas, in particular to a processing method and device for production waste gas containing hydrogen sulfide. This device realizes the purpose of absorbing hydrogen sulfide by using lye by making the exhaust gas containing hydrogen sulfide produced in the production process of viscose fiber react with the high-pressure atomized lye in an impingement flow. Background technique [0002] During the production of viscose fiber, a large amount of waste gas containing hydrogen sulfide will be generated, which seriously affects the personal safety of the staff and the air environment around the factory building. At present, most viscose fiber manufacturers at home and abroad use turbulence towers to wash hydrogen sulfide with alkali, and process waste gas through the absorption of hydrogen sulfide by lye. This technological system has great resistance, the concentration of...
