Abstract

The invention discloses a flue gas circulating combustion type coal-fired cooking stove. A lining barrel (106) made of asbestos is installed in an inner cavity of a coal-fired stove body (109) of the flue gas circulating combustion type coal-fired cooking stove in a sleeved mode. An asbestos air barrel (103) is installed in the asbestos lining barrel in a sleeved mode. When an air blower (117) is started, a valve plate (120) is opened, and a valve plate (121) is closed, flue gas in the cavity of the coal-fired stove body enters an air blowing pipeline (112) through a connection pipeline, a flue gas hopper (116) and a flue gas circulating pipeline (115) and is mixed with supplied air of the air blower; the mixed flue gas is converted into ascending rotating air after passing the air blowing pipeline (112), a vertical pipe (104) and a guider (110), then passes the gaps of stove teeth (111) and enters a combustion cavity for auxiliary combustion; and circulating is conducted in this way, and smoke ash produced in the circulating process is absorbed by water in an ash absorption basin (102). When the air blower is stopped, the valve plate (121) is opened, and the valve plate (120) is closed, the flue gas in the cavity of the coal-fired stove body is exhausted through the flue gas hopper, the connection pipeline and a chimney (122).

Description

Flue gas recycle combustion formula coal-fired stove

1. technical field:

The present invention relates to catering industry and the flue gas recycle combustion formula coal-fired stove of family kitchen use.

2. background technology:

Blowing-type coal-fired stove is widely used in catering industry and family kitchen, wherein, especially with the list of metal shell Hole blowing-type coal-fired stove is in the majority, but because of its design defect, generally there is air blast burning unbalanced, inclined, burning chamber shell Easily scaling loss, heat utilization rate is on the low side, the problem of smoke emissioning pollution environment.

3. summary of the invention:

The present invention design the flue gas recycle combustion formula coal-fired stove of offer by coal furnace, tobacco pipe, suction ash basin and bearing thereof, Aerator, blowing line and the flue gas recirculation pipeline coupled therewith, chimney composition；Described coal furnace by cast housing and Its supporting leg, asbestos inside lining sleeve, stove tooth, asbestos air duct and built-in guider, aerator and blowing line, coal filling hole And outlet flue composition；The rectangle outlet flue of described coal furnace connects with rectangular duct with the smoke inlet of tobacco pipe, the square of tobacco pipe Shape smoke pipeline upper end outlet flue and chimney UNICOM are also provided with valve plate, and its lower end outlet flue enters with flue gas recirculation pipeline Mouth connection is also provided with valve plate, and the outlet flue of flue gas recirculation pipeline connects with the middle part of blowing line, entering of blowing line Aerator is installed on Kou；The cast housing of described coal furnace is by the cylindrical tube of the tubaeform housing on top Yu bottom It is integrally formed formula structure, supporting leg assembling fixing with cylindrical tube, suit asbestos inside lining sleeve, asbestos in cylindrical tube Guider and blowing line are installed in suit asbestos air duct, asbestos air duct in inside lining sleeve；Described tobacco pipe is short cylindrical shape Crossing cigarette heat-dissipating container, the front and rear sides of its external cylindrical surface is provided with smoke inlet and the outlet flue of rectangle, and its inner chamber is fixed Two the pyrotechnics guide plates arranged make to be formed between smoke inlet and outlet flue a serpentine flue, the circle on its top Polycycle cast-iron stove circle is configured on opening.

The basic functional principle of flue gas recycle combustion formula coal-fired stove is: when needs air blast is combustion-supporting, in inhaling ash basin Add water, after the valve plate opening tobacco pipe outlet flue duct coupling bottom outlet flue the valve plate closing top outlet flue, start drum Blower fan, the flue gas that the fire coal in coal furnace produces in combustion passes through its exhanst gas outlet, the serpentine cigarette of tobacco pipe Road to entering blowing line after the duct coupling, flue gas recirculation pipeline of tobacco pipe outlet flue and mixing with the air feed of aerator, Its mixed flue gas becomes up whirlwind after blowing line and vertical tube, guider and enters coal furnace by stove slot gap again Combustion chamber body in combustion-supporting, so move in circles, produced flue dust is absorbed by the water inhaling ash basin therebetween；It is being not required to Stop aerator when wanting air blast combustion-supporting, take out and inhale ash basin and place ash bucket, close tobacco pipe outlet flue duct coupling bottom The valve plate of outlet flue also opens the valve plate of top outlet flue, and the flue gas in coal furnace passes through its exhanst gas outlet, " S " of tobacco pipe Shape flue is discharged through chimney to the duct coupling of outlet flue again.

The invention has the beneficial effects as follows: the thermal efficiency of cooking stove is high, fume emission is few, and air blast area increases and can keep equal Weighing apparatus, the metal shell of coal furnace is unlikely to be burnt, and heat build-up and the radiating effect of tobacco pipe significantly improve.
