Smoke exhaust equipment of coal stove

Abstract

The invention relates to smoke exhaust equipment of a coal stove. The smoke exhaust equipment comprises a smoke exhaust pipe, a dust collecting cover, a connecting pipe and a box body, wherein the dust collecting cover comprises a funneled upper section, a cylindrical middle section and a funneled lower section, the big ends of the upper section and the lower section are fixedly connected with theupper end and the lower end of the middle section respectively, the lower section of the dust collecting cover is inserted into the box body, a valve which is used for cleaning dust is arranged on the small end of the lower section of the dust collecting cover, one end of the smoke exhaust pipe communicates with the coal stove, the other end of the smoke exhaust pipe communicates with the middlesection of the dust collecting cover, a heat exchange water tank is arranged on the outer side of the smoke exhaust pipe, one end of the connecting pipe communicates with the small end of the upper section, and the other end of the connecting pipe is inserted into the box body. According to the smoke exhaust equipment of the coal stove, heat in the smoke exhaust pipe is fully used, so that the utilization rate of the coal stove is increased, the dust collecting effect is achieved, toxic gas in smoke can be treated, and the pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of heating devices, and in particular relates to smoke exhaust equipment for coal stoves. Background technique [0002] In recent years, smog events in my country have become almost normal, seriously affecting the natural environment and people's health, and the prevention and control of smog is imminent. An important reason for the smog is the extensive use of coal furnaces. Large coal-fired sites such as power plants have fixed exhaust gas treatment facilities, while relatively small individual coal-fired furnaces are relatively scattered and small in scale. The smoke exhaust treatment device has caused a great burden on the environment. [0003] In addition, there will be a lot of heat in the exhaust pipe, and direct discharge will cause energy waste and cause huge heat pollution. Recycling it can increase the utilization rate of the coal furnace and avoid heat emission from polluting the environment. ...
