Smoke pipe lengthening section preventing cold wind from flowing backward and containing air filtration for wall hanging stove

Abstract

The invention discloses a smoke pipe lengthening section preventing cold wind from flowing backward and containing air filtration for a wall hanging stove. The lengthening section is characterized byincluding a smoke pipe outer straight pipe, and a smoke pipe inner straight pipe assembly, a wind proof ring is arranged in the smoke pipe inner straight pipe assembly, a support frame used to supporta smoke pipe inner straight pipe is arranged between the smoke pipe outer straight pipe and the smoke pipe inner straight pipe assembly, and a filtration device is mounted between the smoke pipe outer straight pipe and the smoke pipe inner straight pipe assembly. According to the lengthening section, apertures of smoke discharging and air feeding are not changed, the discharging of the content ofCO after the combustion of the wall hanging stove is not affected, and mounting is simple, convenient, and easy to operate.

Description

technical field [0001] The invention relates to the technical field of wall-hung boilers, and more specifically relates to a smoke pipe for a wall-hung boiler. Background technique [0002] With the popularization of coal-to-gas conversion of wall-hung boilers, wall-hung boilers in my country's wall-hung boiler industry have developed relatively rapidly, and they have gradually begun to be popularized and applied in cold and windy regions such as Northeast or Xinjiang. In the shutdown state, there may be cold air pouring back into the wall-hung boiler, and the internal components of the wall-hung boiler may freeze or fail, especially the secondary condensing heat exchanger in the condensing wall-hung boiler freezes and cracks, causing water leakage, which seriously affects the use of the wall-hung boiler Life expectancy and increased after-sales maintenance costs. In addition, in areas such as Northwest China, Beijing and Tianjin, the air quality is poor, and there are many a...

[0002] With the popularization of coal-to-gas conversion of wall-hung boilers, wall-hung boilers in my country's wall-hung boiler industry have developed relatively rapidly, and they have gradually begun to be popularized and applied in cold and windy regions such as Northeast or Xinjiang. In the shutdown state, there may be cold air pouring back into the wall-hung boiler, and the internal components of the wall-hung boiler may freeze or fail, especially the secondary condensing heat exchanger in the condensing wall-hung boiler freezes and cracks, causing water leakage, which seriously affects the use of the wall-hung boiler lifespan, and increases the cost of after-sales maintenance

In addition, in areas such as Northwest China, Beijing and Tianjin, the air quality is poor, and there are many areas containing sand, catkins, and dust. , will be attached to the surface of the burner inside the wall-hung boiler, the fan impeller, the heat exchanger or the tube wall of the condensing heat exchanger, which will cause the performance of the wall-hung boiler to deteriorate, or even malfunction, which will seriously affect the service life of the wall-hung boiler and increase after-sale maintenance cost
