A flue gas treatment device

Abstract

The invention relates to a flue gas treatment device. The flue gas treatment device is characterized by comprising a water tank (1) for accommodating running water; a spiral pipe (5) is arranged in the water tank (1) and connected with a flue gas out chimney for industrial production through a gas inlet pipe (4) and connected with a first purifying box (2) through a first exhaust pipe (10); the first purifying box (2) is filled with a flue gas neutralization solution (11); the first purifying box (2) is communicated with a second purifying box (3) through a second exhaust pipe (14); a graphite layer (16) is arranged on each of the inner upper and the inner lower sides of the second purifying box (3); at least one flue gas neutralization layer (15) is arranged between the two graphite layers (16). The flue gas treatment device has the advantages that heat carried by flue gas is recycled for the second time and reused, so that not only is resource saved, but also the manufacturing cost of enterprises is lowered; meanwhile, poisonous substances in flue gas is purified, so that the environmental pollution can be reduced.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to waste heat recovery and utilization of flue gas and a flue gas purification device. Background technique [0002] With the development of society and the advancement of technology, people's awareness of resource conservation and environmental protection is constantly strengthening. Industrial production processes are generally carried out at high temperatures, so the flue gas produced by it often has a relatively high temperature. Such flue gas If it is directly discharged into the atmosphere, it will not only pollute the environment but also take away a lot of heat, which will cause a waste of resources and increase the cost of the enterprise, which is contrary to people's goal of energy saving and emission reduction. Contents of the invention [0003] The object of the present invention is to propose a flue gas treatment device in order to solve the shortcomings in the...
