Wet type tail gas treatment device of ceramic kiln

Abstract

The invention discloses a wet type tail gas treatment device of a ceramic kiln. The wet type tail gas treatment device comprises a heating device and the ceramic kiln; the heating device is arranged at the lower end of the ceramic kiln; a tail gas pipe is arranged at the upper end of the right side of the ceramic kiln; the tail gas pipe is connected with the upper end of the left side of a cyclone separator; the cyclone separator is connected with an electrostatic precipitator; the electrostatic precipitator is connected with a gas inlet of a gas-liquid separation tank; a recycling pipe is arranged at the lower end of the gas-liquid separation tank; the gas-liquid separation tank is connected with a liquid storage tank under the gas-liquid separation tank through the recycling pipe; a gas outlet of the gas-liquid separation tank is communicated with a wet type absorption tower. The wet type tail gas treatment device of the ceramic kiln is reasonable in structural deign, and a smoke pipe is not easily blocked by smoke dust in tail gas, so that the maintenance cost is reduced; two grades of dust precipitation are utilized so that the dust precipitation effect is good, and the separation of tail gas and steam is realized; moisture in the tail gas entering the wet type absorption tower is greatly reduced; tai gas absorption liquid does not need to be frequently replaced, so that the time and labor are saved and the cost is reduced; effective purification is realized and environment pollution is avoided.

Description

technical field [0001] The invention relates to a tail gas treatment device, in particular to a ceramic kiln wet tail gas treatment device. Background technique [0002] Driven by the wave of building a green and energy-saving society, people's expectations and pursuit of greening the ceramic production process are increasing day by day, and various methods and devices have been adopted to ensure that the production process has as little or no pollution as possible. During the production process of ceramic products, due to the burning of fuels such as natural gas, liquefied petroleum gas, coal gas, light diesel oil, heavy oil, coal, etc., a large amount of sulfur compounds, fluorine compounds, and oxygen and nitrogen compounds will be released. These harmful exhaust gases will cause serious damage to the natural environment. impact, causing acid rain and other natural disasters, affecting the natural environment and human physical and mental health. It is imperative to deve...

Problems solved by technology

[0003] Exhaust gas from ceramic kilns often contains a large amount of smoke and dust. If these waste gases are directly discharged into the air, it will pollute the natural environment; in addition, the exhaust pipes that transport these smoke and dust are often clogged with ash and need to be shut down for maintenance, affecting production efficiency , which increases the production cost; ceramic kiln exhaust gas often contains a large amount of water vapor, and direct absorption will cause a large amount of liquid to be stored in the exhaust gas absorption device, requiring frequent replacement of exhaust gas absorption liquid, which will also cause waste of absorption liquid, which is time-consuming and labor-intensive artificial
