Abstract

The invention relates to the technical field of waste gas treatment, and in particular, discloses an environment-friendly waste gas treatment process and a device thereof, which comprises a cylindrical waste gas treatment pipe as a whole, and the waste gas treatment pipe is provided with a cooling water conveying cavity and a spray water circulation The cooling water conveying cavity is provided with a water conveying pipe, a first exhaust gas conveying pipe passing through the water conveying pipe is arranged between the first mounting plate and the third mounting plate, and a pipe wall on the upper end of the first exhaust gas conveying pipe is provided There is a first spray water outlet; the cavity between the water delivery pipeline and the first waste gas delivery pipeline constitutes a spray water delivery cavity that communicates with the spray water circulation cavity; The collecting spray water circulation mechanism is provided with a water pump, and the water outlet of the water pump is connected with the spray water circulation cavity through a pipeline. The invention effectively increases the contact area between the exhaust gas and the spray water, thereby effectively improving the purification effect of the spray water on the exhaust gas.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an environment-friendly waste gas treatment process and a device thereof. Background technique [0002] In our country, the heat lost by exhaust gas from boilers can be equivalent to the heat released by the complete combustion of tens of millions of tons of standard coal. However, the negative effects of this exhaust gas emission are not limited to energy loss. Pollutants such as sulfur dioxide and nitrogen oxides also seriously affect air quality. According to the analysis of relevant authoritative departments, the culprit of the haze weather is the pollutants discharged in the exhaust gas. This obviously does not meet the requirements of energy saving and emission reduction, and most of the existing exhaust gas treatment devices are limited to heat recovery or environmental protection treatment, and the cost is high, the heat transfer coefficient is low, the tail ...
