Industrial kiln waste heat recovery device

Abstract

The invention discloses an industrial kiln waste heat recovery device, and belongs to the technical field of waste heat recovery. The industrial kiln waste heat recovery device comprises an industrialkiln and a waste heat recovery box, wherein a first heat conduction pipe is connected between the industrial kiln and the waste heat recovery box, and a controller is installed at the upper end of the waste heat recovery box. According to the industrial kiln waste heat recovery device, heat exchange can be carried out between an aqueous solution and waste gas, the heated aqueous solution is guided out to equipment to be heated for use, so that heat in the waste gas is recycled to the maximum extent, the temperature of the waste gas discharged into the environment is reduced, and pollution tothe environment is effectively reduced; meanwhile, an auxiliary heat absorption piece is arranged, so that on one hand, the temperature rise of the aqueous solution can be accelerated, and on the other hand, the adsorption of the heat of the waste gas can be continuously completed in the replacement process of the aqueous solution; a second heat conduction pipe is introduced into the industrial kiln, so that the heat efficiency of the kiln is improved, and the fuel energy consumption is saved; and a purification chamber is arranged, so that harmful gas contained in the waste gas is removed.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery, and more specifically relates to a waste heat recovery device for industrial kilns. Background technique [0002] A kiln is a device made of refractory materials for firing products, and is an essential facility in pottery molding. The tens of thousands of years of human ceramic firing history have accumulated rich kiln styles and experience. From the open-air pile firing on the ground in the primitive society, digging pits and building fires to steamed bun-shaped rising flame round kilns, half-down-flame horseshoe-shaped kilns, Banpo dragon kilns, and duck-egg-shaped kilns, to today's indoor gas kilns, electric kilns, and kiln technology In continuous improvement and development. [0003] Waste heat refers to the sensible heat and latent heat that have not been rationally utilized in the original design of industrial energy-consuming devices that have been put into operation due to...

AI Technical Summary

Problems solved by technology

[0004] The internal heating temperature of the kiln is generally more than 1,000 degrees, and the exhaust gas contains high waste heat, which is generally discharged directly into the air, which wastes a lot of resources and increases production costs.

In addition, kiln exhaust gas often contains a large amount of smoke and dust. If these exhaust gases are directly discharged into the air, it is easy to cause pollution to the environment.
