Energy-saving efficient waste gas treatment device

Abstract

The invention discloses an energy-saving efficient waste gas treatment device. The energy-saving efficient waste gas treatment device comprises a naked flame furnace and a washing tower, wherein an air inlet pipe is connected to the left side of the naked flame furnace, an oxygen supply device is arranged on the right side of the naked flame furnace, a dust absorbing device, a heat exchanger and a first draught fan are respectively arranged on an air conveying pipe of the naked flame furnace; and a second filtering layer, a first filtering layer, a catalyzing device and a spraying pipe are respectively arranged in the washing tower from top to bottom, a bracket is mounted in the washing tower at the lower side of the spraying pipe, a vertical pipe is rotationally mounted in the middle of the bracket, the lower end of the vertical pipe is communicated with the air conveying pipe through a rotating joint, a motor for driving the vertical pipe to rotate is further arranged below the bracket, a plurality of transverse pipes are circumferentially mounted on the side surface of the upper end of the vertical pipe, and a plurality of jetting heads are mounted on the lower sides of the transverse pipes. The energy-saving efficient waste gas treatment device has the beneficial effects that waste is thoroughly purified, the purifying efficiency is high, the environmental pollution is furthest reduced, and the exhausted gas meets the requirements; and meanwhile, the heat energy resource is effectively utilized, the energy is saved, the environment is protected, and the waste of the resources is reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an energy-saving and high-efficiency waste gas treatment device. Background technique [0002] In the iron and steel industry, cement industry, smelting industry, thermal power generation industry and other fields, a large amount of industrial waste gas is bound to be generated during the production and processing process. Most of these industrial waste gases contain large particles of dust, fine particles of impurities, toluene, formaldehyde, and sulfides If harmful components such as pollutants are directly discharged into the atmosphere, it will seriously pollute the atmosphere, affect the hygienic environment, and endanger human health. For the purification of exhaust gas, there are often different treatment methods due to different factors such as exhaust gas composition, environment and temperature. However, some exhaust gases cannot be treated by a single...

AI Technical Summary

Problems solved by technology

However, some exhaust gases cannot be treated by a single treatment method, and need to be treated by a combination of two or more methods.

However, the existing exhaust gas treatment equipment is inconvenient to use and control, the exhaust gas purification efficiency is low, the purification is not thorough, and the emission requirements cannot be met, which is easy to cause pollution to the environment, and the thermal energy resources in the exhaust gas cannot be recycled, which is not energy-saving and environmentally friendly.
