Abstract
The invention discloses an industrial tail gas fine purifier, and relates to the technical field of industrial tail gas purifying. The industrial tail gas fine purifier comprises a tail gas inlet (1), a tail gas outlet (2), an absorption medium inlet (3), an absorption medium outlet (4), a first reaction tower (5), a second reaction tower (6), a third reaction tower (7) and a fourth reaction tower (8), wherein the first reaction tower (5) is connected with the second reaction tower (6) through a U-shaped pipe, the second reaction tower (6) is connected with the third reaction tower (7) through a U-shaped pipe, and the third reaction tower (7) is connected with the fourth reaction tower (8) through a U-shaped pipe. According to the industrial tail gas fine purifier, as nitrogen in tail gas is recycled four times, the recycling rate of nitrogen in tail gas in the urea production technology is increased, consumption in the production process is reduced, emission of harmful industrial tail gas is reduced, devices are horizontally designed, the four devices are stacked to be in place, and installation is convenient.
Description
Technical field
The present invention relates to a kind of industrial tail gas cleaning technique field, be specifically related to a kind of industrial tail gas fine purifiation device.
Background technology
Typically, processing method to industrial tail gas is to use catalyst that toxic gas is converted into non-toxic gas to discharge in the industrial production, or use once washing absorption process to carry out absorbing then emptying, but said method makes processing cost high, produce and consume height, tail gas recycle effect is bad, is easily formed secondary pollution.
Summary of the invention
It is an object of the invention to provide a kind of industrial tail gas fine purifiation device, it realizes four recovery of vapour ammonia in tail gas by one group of equipment, improves the response rate of vapour ammonia in urea production process tail gas.
nullIn order to solve the problem existing for background technology，The present invention is by the following technical solutions: it comprises inlet exhaust gas 1、Offgas outlet 2、Absorbing medium import 3、Absorbing medium outlet 4、First reaction tower 5、Second reaction tower 6、3rd reaction tower 7、4th reaction tower 8，Offgas outlet 2 is at the top of the 4th reaction tower 8，Absorbing medium import 3 is above the lower section of offgas outlet 2 and the 4th reaction tower 8，Inlet exhaust gas 1、Absorbing medium outlet 4 is connected with the first reaction tower 5，First reaction tower 5 is connected with the second reaction tower 6，Second reaction tower 6 is above the first reaction tower 5 and the lower position of the 3rd reaction tower 7，3rd reaction tower 7 is above the second reaction tower 6 and the lower position of the 4th reaction tower 8，4th reaction tower 8 position below absorbing medium import 3 and above the 3rd reaction tower 7，First reaction tower 5、Second reaction tower 6、3rd reaction tower 7 the 4th reaction tower 8 is all connected by U-tube.
The method have the advantages that
1, the consumption of production process is reduced；
2, the discharge of noxious industry tail gas is reduced；
3, the response rate of vapour ammonia in urea production process tail gas is improved.
Accompanying drawing illustrates:
Fig. 1 is the Structure and Process schematic diagram of the present invention.
Detailed description of the invention
nullWith reference to Fig. 1，A kind of industrial tail gas fine purifiation device，It comprises inlet exhaust gas 1、Offgas outlet 2、Absorbing medium import 3、Absorbing medium outlet 4、First reaction tower 5、Second reaction tower 6、3rd reaction tower 7、4th reaction tower 8，Offgas outlet 2 is at the top of the 4th reaction tower 8，Absorbing medium import 3 is above the lower section of offgas outlet 2 and the 4th reaction tower 8，Inlet exhaust gas 1、Absorbing medium outlet 4 is connected with the first reaction tower 5，First reaction tower 5 is connected with the second reaction tower 6，Second reaction tower 6 is above the first reaction tower 5 and the lower position of the 3rd reaction tower 7，3rd reaction tower 7 is above the second reaction tower 6 and the lower position of the 4th reaction tower 8，4th reaction tower 8 position below absorbing medium import 3 and above the 3rd reaction tower 7，First reaction tower 5、Second reaction tower 6、3rd reaction tower 7 the 4th reaction tower 8 is all connected by U-tube.
The present invention is by four recovery of vapour ammonia in tail gas, improve the response rate of vapour ammonia in urea production process tail gas, reduce the consumption of production process, decrease the discharge of noxious industry tail gas, and equipment is horizontal design, and four equipment stack in place, easy for installation.
