Circulating washing and purifying treatment device for kiln waste gas

Abstract

The invention discloses a circulating washing and purifying treatment device for kiln waste gas. The device comprises a waste gas channel I, a waste gas channel II, a waste gas channel III and a washing and purifying chamber, the waste gas channel II is arranged on one side of the waste gas channel I, the waste gas channel III is arranged on one side of the waste gas channel II, and the washing and purifying chamber is arranged on one side of the waste gas channel III; the waste gas of the kiln is fully purified through layer-by-layer circulating spraying, filtering and purifying, and is discharged in a water vapor state, so that the discharge standard is completely met; and the purified water vapor is heated by utilizing a large amount of heat carried by the kiln waste gas, so that the water vapor is discharged in a cleaner state.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a recycling cleaning and purification treatment device for kiln waste gas. Background technique [0002] With the rapid development of my country's industrial level, environmental problems are becoming increasingly apparent. The country has successively issued corresponding policies for environmental governance. In recent years, people's awareness of environmental protection has continued to increase, and the call for restoring "green mountains and green waters" has continued to increase. Environmental protection economy, realizing the sustainable development of green economy has become the trend of the times; [0003] The kiln is an essential facility in pottery molding, but a large amount of waste gas will be generated during the firing process. The waste gas contains a large amount of fine particles and sulfur dioxide and other substances,...

Problems solved by technology

[0003] The kiln is an essential facility in pottery molding, but a large amount of waste gas will be generated during the firing process. The waste gas contains a large amount of fine particles and sulfur dioxide and other substances, which will cause serious environmental pollution. People live in this environment for a long time It is very easy to induce respiratory and lung diseases, but the following problems often exist in the existing cleaning and purification equipment: 1) The structure is relatively simple, and the exhaust gas produced cannot be completely purified, and there will still be some pollution when it is directly discharged into the atmosphere. pollution; 2) The exhaust gas discharged from the kiln carries a large amount of heat source, and the large amount of heat carried will be directly discharged, resulting in a waste of energy
