Air circulated heating and purifying device for coal-fired furnace and coal-fired furnace using air circulated heating and purifying device and processing method for coal-fired furnace

Abstract

The invention provides an air circulated heating and purifying device for a coal-fired furnace and the coal-fired furnace using the air circulated heating and purifying device and a processing method for the coal-fired furnace. The air circulated heating and purifying device comprises a heat pipe exchanger, an induced draft fan and an air filtering device. A heat exchange pipe is installed in the heat pipe exchanger, and the heat exchange pipe is filled with a heat transfer substance. A horizontally placed smoke discharging pipe is extended from a smoke discharging port of the coal-fired furnace. The lower part of the heat pipe exchanger is installed in the smoke discharging pipe. One side of the upper part of the heat pipe exchanger is provided with an air inlet. One side, opposite to the air inlet, is provided with an air outlet. The induced draft fan is installed at the air inlet or the air outlet. The air filtering device is installed at the air inlet or the air outlet. The air circulated heating and purifying device is installed at the smoke outlet pipeline of the coal-fired furnace, so the heat quantity in the smoke can be effectively recycled and the indoor air can be purified simultaneously. The air circulated heating and purifying device is capable of greatly improving the utilization efficiency of the smoke heat quantity of the coal-fired furnace, so the air can be heated by only smaller heat quantity.

Description

technical field [0001] The invention belongs to the field of coal-fired combustion equipment, and relates to an air circulation heating and purification device for coal-fired stoves and a coal-fired stove using the same, in particular to an air circulation system for coal-fired stoves based on heat pipe heat transfer. A circulating heating and purification device and a coal-fired furnace using the same. Background technique [0002] At present, households in some areas in northern my country, especially townships and rural households, generally use earth heating for heating. Due to the unscientific design of stoves, some coal cannot be completely burned and is discharged with smoke. The utilization rate is low. Not only the coal consumption is large, And it will cause serious air pollution. Moreover, in real life, while the majority of rural users are heating, they also hope that the stove can be used for cooking at the same time, such as boiling water, cooking and cooking. ...
