Kiln tail-gas energy-saving and emission-reducing processing equipment

Abstract

The invention discloses kiln tail-gas energy-saving and emission-reducing processing equipment, which comprises a heat-exchanging chamber and a smoke-gas channel, wherein the smoke-gas channel is communicated with the inner part of the heat-exchanging chamber, the heat exchange of combustion-supporting air and hot smoke gas is carried out in the heat-exchanging chamber, and the smoke gas after being subjected to heat exchange is then introduced into the smoke-gas channel for smoke-dust settlement. When the kiln tail-gas energy-saving and emission-reducing processing equipment works, the heat exchange of cold air and the hot smoke gas is carried out in the heat-exchanging chamber in the mode of convection, so that the heat-transferring efficiency is high, the temperature of the combustion-supporting air entering a kiln can be increased, and meanwhile, the discharging temperature of the hot smoke gas is decreased; when the smoke gas after being subjected to heat exchange is introduced into the smoke-gas channel, the advancing speed becomes lower, which is favorable to the sufficient settling of smoke dust. Practice indicates that the temperature of the combustion-supporting air after being subjected to heat exchange can be increased to 120 to 150 DEG C, and 70% smoke dust can be reduced in the smoke gas after a settling process, so that the kiln tail-gas energy-saving and emission-reducing processing equipment has remarkable energy-saving and emission-reducing effects and conforms to the requirement of environmental protection.

Description

[0001] technical field [0002] The invention relates to equipment for energy-saving and emission-reduction treatment of kiln tail gas. [0003] Background technique [0004] At present, during the working process of the kiln, a large amount of tail gas will be generated, and the temperature of the tail gas is often relatively high. If it is discharged outside without treatment or only with simple treatment, it will cause air pollution on the one hand, and the heat taken away is also A colossal waste. [0005] Contents of the invention [0006] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a kiln tail gas energy-saving and emission-reduction treatment equipment, which has remarkable energy-saving and emission-reduction effects and meets the requirements of environmental protection. [0007] To achieve the above object, the present invention adopts the following technical solutions: [0008] A kiln tail gas energy-savin...
