Abstract
A waste gas back-flame combustion purification device comprises a waste gas inlet, a smoke back-flame temperature rising device, an auxiliary burner, a first combustion chamber, a smoke back-flame pipe, a smoke conveying pipe, a second combustion chamber, a heat exchanger, a speed regulating fan and a waste gas outlet; the smoke back flame temperature rising device consists of a smoke back flame pipe and a smoke conveying pipe; the waste gas enters the smoke back-flame temperature rising device, the smoke with the flame flows back from the first combustion chamber, the smoke with the flame is indirectly heated and raised in temperature and then ignited by the auxiliary combustor, the ignited waste gas is combusted in the first combustion chamber, and the smoke with the flame generated by combustion flows back to the second combustion chamber through the smoke back-flame pipe in the smoke back-flame temperature rising device to be continuously combusted. The smoke backflow with flame in the first combustion chamber enables the newly-entered waste gas in the smoke conveying pipe to be heated and become inflammable; the waste gas which is not completely combusted can be continuously combusted in the second combustion chamber, and the flue gas which is completely combusted is subjected to heat exchange through the heat exchanger and then is discharged from the waste gas outlet through the speed regulating fan.
Description
Technical Field
The utility model relates to a waste gas burning field especially relates to a waste gas back flame burning purifier, realizes the purpose of exhaust purification processing.
Background
The waste gas back flame combustion purification device is a device for reducing pollutant emission by combustion of smoke and waste gas containing pollutants. In a normal state, low-concentration flue gas and waste gas are difficult to combust, and organic pollutant gas, carbon monoxide, smoke dust and the like are usually combusted by heating or auxiliary combustion or catalytic combustion and the like, so that the aim of purifying pollutants is fulfilled; at present, the treatment technology or the treatment device for the waste gas and the flue gas has the advantages of easy treatment (easy combustion) of high concentration, high cost for treating low-concentration waste gas and undesirable effect.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the above-mentioned not enough of prior art and product, make following design: the waste gas back-flame combustion purification device comprises a waste gas inlet, a smoke back-flame temperature rising device, an auxiliary burner, a first combustion chamber, a smoke back-flame pipe, a smoke conveying pipe, a second combustion chamber, a heat exchanger, a speed regulation fan and a waste gas outlet.
The waste gas back-flame combustion purification device is characterized in that the smoke back-flame temperature rising device consists of a smoke back-flame pipe and a smoke conveying pipe; the auxiliary burner is positioned in the first fuel chamber above the flue gas flame returning temperature rising device; the speed regulation fan is positioned at the tail part of the device and plays a role in controlling the fuel speed of waste gas, the discharge speed of the waste gas and the retention time of the waste gas in the device.
The temperature of the flue gas back-flame combustion purifier is increased by the flue gas back-flame temperature increasing device, so that flue gas with flame flows back to the second combustion chamber downwards after being combusted in the first combustion chamber, and cold waste gas newly entering a smoke conveying pipe is indirectly heated in the backflow process, so that the newly entering waste gas is inflammable.
The waste gas enters a smoke back flame combustion purifier, the smoke with flame flows back from a first combustion chamber and is ignited by an auxiliary burner after being heated indirectly, the ignited waste gas is combusted in the first combustion chamber, and the smoke with flame generated by combustion flows back to a second combustion chamber through a smoke back flame pipe in the smoke back flame purifier and is continuously combusted. The smoke backflow with flame in the first combustion chamber enables the newly-entered waste gas in the smoke conveying pipe to be heated and become inflammable; the unburned and complete exhaust gas can continue to burn in the second combustion chamber. The flue gas which is completely combusted is subjected to heat exchange through the heat exchanger and then is discharged from the waste gas outlet through the speed regulating fan, so that the aim of treating pollutants such as CO, organic gas pollutants, smoke dust and the like in the waste gas is fulfilled.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
as shown in fig. 1, the exhaust gas back-flame combustion purification device comprises: the device comprises a waste gas inlet (1), an air inlet (2), a smoke back flame temperature rising device (3), an auxiliary burner (4), a first combustion chamber (5), a smoke back flame pipe (6), a smoke conveying pipe (7), a second combustion chamber (8), a heat exchanger (9), a speed regulating fan (10) and a waste gas outlet (11).
According to the waste gas combustion purification device, waste gas mixed by the waste gas inlet (1) and the air inlet (2) enters the smoke back flame temperature rising device (3) to heat waste gas newly entering from the smoke conveying pipe (7), the heated waste gas is ignited by the auxiliary burner (4), the ignited waste gas is combusted in the first combustion chamber (5), and the flame smoke generated by combustion flows back to the second combustion chamber (8) through the smoke back flame pipe (6) in the smoke back flame temperature rising device (3) to be continuously combusted; the flue gas with flame flows back to heat the waste gas newly entering from the smoke conveying pipe (7) to be inflammable, the waste gas which is not completely combusted is continuously combusted in the second combustion chamber (8), and the completely combusted flue gas is subjected to heat exchange by the heat exchanger (9) and then is discharged from the waste gas outlet (11) by the speed regulating fan (10), so that the purpose of treating pollutants such as CO, organic gas, smoke dust and the like in the waste gas is achieved.
A waste gas back flame combustion purification device, the smoke back flame temperature rising device (3) is composed of a smoke back flame pipe (6) and a smoke conveying pipe (7); the auxiliary burner (4) is positioned in a first fuel chamber (5) above the flue gas flame returning warmer (3); the speed regulation fan (10) is positioned at the tail part of the device and plays a role in controlling the fuel speed of waste gas, the discharge speed of the waste gas and the retention time of the waste gas in the device.
The temperature of the flue gas flame returning combustion purification device (3) is increased, the flue gas with flame generated by the combustion of a first combustion chamber (5) flows back to a second combustion chamber downwards, and the cold waste gas newly entering a smoke conveying pipe (7) is indirectly heated in the backflow process.
The above is only the preferred embodiment of the present invention, so the range of the implementation of the present invention can not be determined according to the above, and the equivalent changes and decorations made according to the content of the present invention should all belong to the scope covered by the present invention.
