Ceramic kiln exhaust gas residual heat recovery apparatus

Abstract

The invention discloses a ceramic kiln exhaust gas residual heat recovery apparatus, which comprises a boiler body, a flue gas pipe is arranged at the upper end of the boiler body, a draft fan is arranged on the flue gas pipe, and the flue gas pipe is connected with the left side of an electrostatic precipitator; dust collecting electrodes are arranged in the electrostatic precipitator, a flue-dust retainer is arranged at the lower end of the electrostatic precipitator, and a detachable dust collecting bag is arranged at the lower end of the flue-dust retainer; the upper right end of the electrostatic precipitator communicates with an exhaust pipe, and a vibrator is arranged at the lower right end of the electrostatic precipitator; the electrostatic precipitator is connected with the left bottom of a green body drying box through the exhaust pipe, and an adsorption box is arranged on the exhaust pipe. The ceramic kiln exhaust gas residual heat recovery apparatus is convenient to use, decreases the frequency of shutdown for dust removal, reduces the maintenance cost, has a good dust removal and purification effect, and increases the efficiency of dust removal; the ceramic kiln exhaust gas residual heat recovery apparatus can purify harmful gas in exhaust gas, so the environment is protected; moreover, by using exhaust gas to dry ceramic green bodies and heat cold water, the ceramic kiln exhaust gas residual heat recovery apparatus can reduce resource waste and cost.

Description

technical field [0001] The invention relates to a tail gas treatment device, in particular to a ceramic kiln tail gas waste heat recovery device. 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. The internal heating temperature of the kiln is generally more than 1,000 degrees, and the exhausted flue gas has high heat, which is generally discharged directly into the air, which wastes a lot of resources and increases production ...

AI Technical Summary

Problems solved by technology

The internal heating temperature of the kiln is generally more than 1,000 degrees, and the exhausted flue gas has high heat, which is generally discharged directly into the air, which wastes a lot of resources and increases production costs.

In addition, the exhaust gas of ceramic kilns often contains a lot of smoke and dust. If these exhaust gases are directly discharged into the air, the natural environment will be polluted.
