White smoke elimination spraying tower based on pillow-like plate type heat exchanger

Abstract

The invention discloses a white smoke elimination spraying tower based on a pillow-like plate type heat exchanger. The white smoke elimination spraying tower comprises a tower body and a chimney, wherein a liquid collecting tank with spraying cooling liquid is arranged at the bottom in the tower body; the tower body is provided with a smoke inlet above the liquid collecting tank; a plurality of pillow-like plate type coolers and a spraying device are arranged above the smoke inlet in the tower body; the pillow-like plate type heat exchanger reheater is correspondingly arranged in the chimney;the plurality of pillow-like plate type coolers comprise a first pillow-like plate type cooler, a second pillow-like plate type cooler and a third pillow-like plate type cooler in sequential corresponding arrangement from top to bottom. The heat transfer enhancement requirements are met; the cooler resistance is small; dirt cannot be easily generatedis not liable to occur; the equipment operationcosts is are low; the water consumption quantity is reduced; the smoke heat is recovered to cooling media to be reutilized; the problem of white smoke plume is thoroughly eliminatedsolved; the heat exchange efficiency is high; the heat exchange temperature difference is small; the heat recovery rate is high; the modular design and the vertical installation are used; , so that the structure is compact; , and the occupied area is small; and the working condition adaptability is high.

Description

technical field [0001] The invention belongs to the field of flue gas cooling, reheating, whitening and waste heat recovery, and in particular relates to a flue gas whitening spray tower based on a pillow-plate heat exchanger. Background technique [0002] Due to the development of industry, the problem of environmental pollution is becoming more and more serious, which has caused the country to attach great importance to environmental protection. The use of national laws and regulations and public opinion propaganda has made the whole society pay attention to and deal with pollution problems. With the strengthening of the country's awareness of environmental protection, the country has issued a series of laws and regulations to improve pollutant discharge standards, which requires industrial enterprises to carry out advanced treatment of pollutants to meet the national discharge standards. [0003] Flue gas desulfurization is an important process before industrial waste gas...

AI Technical Summary

Problems solved by technology

This process technology is mature and has a long history, but there are also disadvantages such as the flue gas carrying water vapor out of the chimney together, which consumes a lot of water; the waste heat is not utilized, resulting in energy waste; the visual pollution of "white smoke" at the chimney outlet, etc.
