Abstract
The invention discloses a tail gas processing method. A three-grade counter-current mode is adopted to process the tail gas; a first absorbing tower, a second absorbing tower, and a third absorbing tower are parallelly arranged; the tail gas is connected to a tail gas inlet pipe, and at the same time a water inlet pipe is connected to a water source. The tail gas goes through the first absorbing tower, the second absorbing tower, and the third absorbing tower and finally is discharged out of the system from the gas outlet pipe. The provided method can effectively remove tail gas generated in the electroplate technology and is safe and environment-friendly.
Description
Technical field
The present invention relates to a kind of exhaust gas treating method, specifically a kind of for the exhaust gas treating method in electroplating technology.
Background technology
Along with the reinforcement of environmental consciousness, the requirement of people to environmental protection is more and more higher, the pollution sources of heavy contamination is continued to increase to the dynamics of regulation.At present in electroplating technology, tail gas takes the mode of directly discharge, causes environmental pollution, does not meet environmental requirement.
Summary of the invention
The object of this invention is to provide a kind of exhaust gas treating method, adopt the method can effectively remove the tail gas produced in electroplating technology, safety and environmental protection.Adopt three stage countercurrent modes to absorb waste gas, the amount of conserving water, the tail gas concentration that in first order absorption tower, absorbing liquid absorbs is high, easily process further; Third level absorption tower, absorbing liquid concentration is high, effectively removes waste gas in tail gas.
Object of the present invention is achieved through the following technical solutions:
A kind of exhaust gas treating method, is characterized in that: the method adopts the mode of three stage countercurrents to process tail gas, and concrete steps are as follows:
1) the first absorption tower, second absorption tower and the 3rd absorption tower are arranged in juxtaposition, absorbing liquid is equipped with in single absorption tower, tail gas air inlet pipe A is provided with in the first bottom, absorption tower, exceed absorbing liquid liquid level position be connected with tracheae on the first top, absorption tower, tracheae is connected to second absorption tower bottom, be connected to the 3rd bottom, absorption tower by second absorption tower top, be connected with escape pipe B on the 3rd top, absorption tower; Water inlet pipe C is provided with in the 3rd bottom, absorption tower, water pipe is connected with lower than absorbing liquid liquid level position on the 3rd top, absorption tower, water pipe is connected to second absorption tower bottom, is connected to the first bottom, absorption tower by second absorption tower top, connects outlet pipe D on the first top, absorption tower;
2) be connected to by tail gas on tail gas air inlet pipe A, water inlet pipe C is connected with water source simultaneously;
3) tail gas is after the first absorption tower, second absorption tower and the process of the 3rd absorption tower, is discharged by escape pipe B.
In the present invention, absorbing liquid and tail gas suitable.Absorbing liquid can change targetedly.Safety air vavle is provided with above the first absorption tower, second absorption tower and the 3rd absorption tower.Blowoff valve is provided with bottom the first absorption tower, second absorption tower and the 3rd absorption tower.
It is not very big that the present invention is applicable to tail gas amount, or the system of tail gas composition more complicated, and absorbing liquid can change targetedly.
The present invention can effectively remove the tail gas produced in electroplating technology, safety and environmental protection.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of three stage countercurrent modes in the present invention.
