Environment-friendly industrial exhaust gas waste heat recycling device

Abstract

An environment-friendly industrial exhaust gas waste heat recycling device comprises a body and is characterized in that a heat exchange box is arranged inside the body and internally filled with tap water; a heat exchange pipe is arranged inside the heat exchange box, and the inlet end of the heat exchange pipe communicates with a connecting pipe; a condensing pipe is arranged on the heat exchange pipe; a gas purifying box is arranged on the top of the body; a circulating gas pipe is arranged on the right side of the gas purifying box; an air quality detecting instrument is arranged on the circulating gas pipe; the space between the body and a liquid level sensor is vacuum; the body is wrapped with heat preservation cotton; a water inlet pipe is arranged on the body; a submerged pump is arranged at the bottom of the heat exchange box; a second reversing valve is mounted on a circulating water pipe; a hot water pipe is arranged on the second reversing valve; and a water temperature sensor is arranged on the hot water pipe. A rough filter box roughly filters industrial exhaust gas, and the situation that dust in the exhaust gas blocks the heat exchange pipe is avoided; the heat exchange area is increased through the spiral heat exchange pipe, so that the waste heat recycling effect of the exhaust gas is better; and gas discharging of the device is more environmentally friendly, heat dissipation is little, and the heat exchange efficiency is high.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery, in particular to an environment-friendly industrial waste gas waste heat recovery device. Background technique [0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air generated during fuel combustion and production processes in the factory area. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, Carbon monoxide, sulfuric acid mist, lead and mercury, beryllium compounds, soot and productive dust are discharged into the atmosphere and will pollute the air. These substances enter the human body through the respiratory tract through different routes. more serious harm to people's health.

AI Technical Summary

Problems solved by technology

[0003] In the process of chemical production and operation, industrial waste gas is often produced. These waste gases contain more harmful impurities such as dust particles and have high heat. Therefore, these high-calorie industrial waste gases can be exchanged in the form of heat exchange. , to recover heat to realize energy recycling; the existing industrial exhaust gas waste heat recovery device has a poor filtering effect on dust particles in the exhaust gas, which is easy to cause blockage inside the device, and the heat loss during the heat exchange process is relatively large , low heat transfer efficiency
