Abstract
An industrial furnace soot blower is used for effective soot blowing on the heat exchange surface on the tail of various industrial furnaces. The self-mixing gas industrial furnace soot blower consists of a shock wave occurrence tank, a gas valve, a combustion-supporting air valve, a gas-air mixing pipe and a spark plug. The shock wave occurrence tank is a cylindrical tank body with the upper surface provided with a gas and combustion-supporting air inlet and the lower surface provided with a gas and deflagration gas outlet. The gas-air mixing pipe is a round pipe, which completely mixes gas with combustion-supporting air by using injection principle. The spark plug is on the shock wave occurrence tank, and used to ignite combustible gas. The soot blower is designed as an open vessel, which fundamentally eliminates the risk of that mixed combustible gas explodes in a sealing tank. The regulation of the soot blower energy magnitude is flexible and accurate, and the whole soot blower is simple in system structure, convenient in installation, easy in operation, safe and reliable.
Description
Technical field
The utility model relates to the device that a kind of industrial furnace heat exchanger surface blows ash, especially when being mixed into burning mixture, combustion gas and air do not need compressed air pump, fundamentally got rid of the danger that burning mixture is blasted in closed conduit, simple in structure, safe and reliable.
Background technology
At present, known gas soot blower is made up of fuel gas bottle, compressed air pump, gas connection pipe road, blending tank, some cupping jar, layer distributor, flame conveyance conduit, flame-retardant device, surge generator, electrically operated valve etc.In this soot blower, combustion gas is wanted to mix in blending tank earlier with combustion air, delivers in layer distributor along conveyance conduit again, behind layer distributor, delivers in the shock wave generator tube again.In combustion gas distribution process, the fuel gas that mixes with air is full of the whole system pipe-line system all the time, has not only wasted combustion gas, and exists the danger that the sealing blast takes place; In ignition process, want earlier at a cupping jar mid point fire, fuel gas buring flame front face after lighting passes in the shock wave generation tank through layer distributor along pipeline, light air mixture wherein, produce detonation, at this moment, in time do not open if the valve of pipe end hinders for some reason, the mixed combustible gas body of lighting will produce blast in the conveyance conduit of sealing.In addition, the pipe arrangement complexity of this gas soot blower, the installing engineering amount is big, the fault rate height.
Summary of the invention
In order to overcome existing gas soot blower above shortcomings, the utility model provides a kind of combustion gas self mixing type industrial furnace soot blower, this soot blower has been cancelled compressed air pump, gas connection pipe road, blending tank, some cupping jar, layer distributor, flame conveyance conduit, flame-retardant device, fundamentally eliminated the danger that burning mixture is blasted in closed conduct, and it is simple in structure, easy for installation, processing ease, safe and reliable.
The technical scheme that its technical problem that solves the utility model adopts is: design has combustion-supporting air valve on the shock wave generation tank, the negative pressure characteristic of utilizing industrial furnace heat exchanger flue to have, automatically upgrade required combustion air in the shock wave generation tank, cancelled air pressure pump; Design has the gas-air mixing tube on the shock wave generation tank, the inner end of gas-air mixing tube has gas nozzle and combustion air inlet, the other end has spark plug, the axis of the axis of gas-air mixing tube and shock wave generation tank is for parallel, utilize the high pressure of fuel gas injection, use the combustion air in the injector principle automatic injecting spray shock wave generation tank, and fully mix, cancelled an independent blending tank and a layer distributor with combustion air; On gas-air injection mixing tube, design ignition spark plug, cancelled independent some cupping jar and complicated flame conveyance conduit.
The beneficial effects of the utility model are: fundamentally eliminated the danger that burning mixture is blasted in closed conduct, compressed air pump, gas connection pipe road, blending tank, some cupping jar, layer distributor, flame conveyance conduit, flame-retardant device have been cancelled, simplified the structure of entire equipment, reduce manufacturing cost, improved the convenience of the security and the equipment operation of soot blower.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model principle schematic.
Among Fig. 1,1, the shock wave generation tank, 2, gas valve, 3, fuel gas bottle, 4, the combustion air valve, 5, spark plug, 6, switch board, 7, industrial furnace wall, 8, the gas-air mixing tube.
Specific embodiments
During the work of industrial furnace soot blower, combustion gas enters into gas-air mixing tube (8) by fuel gas bottle (3) through gas valve (2), combustion air in the injection shock wave generation tank (1), and in gas-air mixing tube (8), mix, mixed fuel gas enters into shock wave generation tank (1) further to be mixed, when the combustion gas mixing end-of-job, automatic self-closing gas valve (2).
Spark plug (5) work, light the air mixture in the gas-air mixing tube (8), the air mixture of being lighted enters in the shock wave generation tank (1) through the gas-air mixing tube, light the air mixture in the shock wave generation tank (1), produce detonation, the high temperature and high pressure gas that detonation produces is sprayed in the industrial furnace furnace wall (7) by spout after ovennodulation, form shock wave one, within the walls dust stratification face is blown ash.
After detonation finishes, open combustion air valve (4), utilize the interior negative pressure of stove of shock wave generation tank spout, sucking extraneous air enters in the shock wave generation tank (1) through combustion air valve (4), and with in the suction of the residual gas in the shock wave generation tank (1) stove, upgrade the combustion air in the shock wave generation tank (1), close combustion air valve (4) then, prepare for blowing ash next time.
All control procedures are finished automatically by switch board (6).
Claims (3)
1, combustion gas self mixing type industrial furnace soot blower, form by shock wave generation tank, combustion air valve, gas valve, gas-air mixing tube, spark plug, it is characterized in that: the combustion air valve is installed at the top at the shock wave generation tank, sidepiece outside shock wave generation tank jar is installed the gas-air mixing tube, on the gas-air mixing tube spark plug is installed.
2, combustion gas self mixing type industrial furnace soot blower according to claim 1 is characterized in that: the inner end of gas-air mixing tube has gas nozzle and combustion air inlet, and the other end has spark plug.
3, combustion gas self mixing type industrial furnace soot blower according to claim 1 is characterized in that: the axis of the axis of gas-air mixing tube and shock wave generation tank is for parallel.
