Combustion furnace tail gas purification treatment utilizing device

Abstract

A combustion furnace tail gas purification treatment utilizing device comprises a heat exchanging chamber, and is characterized in that the outer surface of the heat exchanging chamber is covered with heat preserving cotton; a bent coiled pipe is arranged in the heat exchanging chamber; a gas inlet is formed in the left end of the coiled pipe; the exterior of the coiled pipe is sleeved with a sleeve; the surface of the sleeve is evenly provided with a plurality of heat exchanging leakage holes; a water distributing disk is arranged in the heat exchanging chamber; a plurality of spraying heads are arranged at the bottom of the water distributing disk; the right end of the coiled pipe is communicated with a pressure boosting pipe which is provided with a pressure boosting draught fan; a cyclone separator is installed at the right end of the pressure boosting pipe; a conveying pipe is arranged on the top of the cyclone separator, and is provided with a filtering box; and a plurality of filtering nets are arranged in the filtering box. Tail gas with a high temperature and high heat characteristic exists in the coiled pipe of the combustion furnace tail gas purification treatment utilizing device to heat the sleeve, and exchanges heat with tap water, the staying time of the tail gas in the heat exchanging chamber is prolonged by the bent coiled pipe, so that the tap water can be sufficiently heated, and the heat transfer efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of environmental protection machinery and equipment, in particular to a device for purification, treatment and utilization of exhaust gas from a combustion furnace. Background technique [0002] Combustion furnace, electric arc combustion furnace, also known as carbon-sulfur combustion furnace, or electric arc furnace for short, uses a high-voltage, high-frequency oscillating circuit to form an instantaneous large current to ignite the sample, and the mixed gas produced after the sample burns rapidly under oxygen-enriched conditions. The chemical analysis program is an equipment that can quantitatively and quickly analyze the carbon and sulfur content in the sample. It is the crystallization of many years of hard work by Chinese physicists. [0003] The combustion furnace will produce a large amount of tail gas during the combustion of fuel. As an additional product generated during the combustion reaction, ...

Problems solved by technology

[0003] The combustion furnace will produce a large amount of tail gas during the combustion of fuel. As an additional product generated during the combustion reaction, the tail gas has the characteristics of high heat. Therefore, the utilization of the combustion furnace tail gas is a major trend at present. In the combustion furnace tail gas Contains more toxic and harmful substances such as carbon monoxide and sulfur dioxide, and inhalable particulate matter such as dust particles. The existing combustion furnace tail gas treatment device has an unsatisfactory heat recovery effect on the tail gas, and the heat transfer efficiency is low. The purification effect on the combustion furnace tail gas is relatively low. Difference
