Description
Affiliated technical field
This practical energy-conservation soot blower of a kind of novel gas that relates to; The gray technology field of blowing that relates to non-burning type material surface; Be particularly useful for various heat-transfer surfaces and implement to blow the technical field of ash, the technical field that combustion gas mixing distribution portion, the igniting that is specifically related to the fuel gas energy-saving soot blower purges partly, spout is isolated the air curtain part and part of detecting is proofreaied and correct in debugging.
Background technology
Its cleaning is kept in dust stratification on the various heat-transfer surfaces and slagging scorification, is a kind of means that guarantee the heat-transfer surface safety and economic operation.In general, guarantee that the heat-transfer surface cleaning can make the thermal efficiency improve 1-5%.Be deposited on dust stratification and slagging scorification on the heat-transfer surface, little by little thickening becomes dust stratification layer or slagging scorification layer, removes as untimely, and then dust stratification and slagging scorification will be serious day by day, and the heat exchange efficiency of heat-transfer surface reduces, the serious waste energy.According to test, dust stratification coking layer thermal conductivity factor has only the 1/400-1/1000 of metal pipe-wall.Therefore behind the heat-transfer surface dust stratification, possibly be compelled the deashing of stopping work, cause the unplanned parking of enterprise, cause unnecessary economic loss.
Present means are to adopt the soot blower selective sootblowing or in flue gas, add ash cleaning agent.But most heating surfaces are equipped with steam soot-blower, also have part to be equipped with compressed air soot-blowing, sonic soot blowing equipment, gas soot blower.It is high that but the shortcoming of steam soot-blower is power consumption, and equipment dependability is poor, maintenance workload is big and the exchange hot side diminishes evil, though heat-transfer surface has been equipped with mostly, service efficiency is low, and many places are in idle state.Compressed air soot-blowing, sonic soot blowing equipment blow grey energy intensity to reach sphere of action inadequately limited, and service efficiency is low, and many places are in idle state.The combustion gas soot blower is to mix by a certain percentage with air with fuel gas, and through igniting, gaseous mixture forms detonation under certain condition, and burning velocity is per second 1000-7000m, and moment causes extremely high pressure, and produces ultrasonic " shock wave ".The dust stratification and the slagging scorification of mainly removing to purge heat-transfer surface with shock wave, high-speed jet, three kinds of forms of sound wave, but the uncertainty that combustion gas soot blower in the market exists that gas consumption is big, fuel gas and air are lighted generation ultrasonic " shock wave ", blow grey intensity and can not adjust according to heat-transfer surface dust stratification and slagging scorification, can not proofread and correct blowing grey intensity.There is serious combustible gas waste, and is difficult to guarantee high temperature heat exchange top blast ash effect.
Summary of the invention
Big for the gas consumption of the combustion gas soot blower that solves present use, as to produce ultrasonic " shock wave " uncertainty.The utility model provides a kind of novel gas energy-conservation soot blower, not only economizes the moral ability, and can carry out blowing grey intensity
The schoolJust, and more reliable.
Mouth, spout are proofreaied and correct in header, isolation air curtain apparatus, detection to the utility model, central control module, centralized control module, Impulsive tank connect to form through air hose, mixing tube, pulse tube, compensating duct on the spot by distributing, and connected mode is flange or welding; It is characterized by mixing tube grows up in 5 meters; The fuel gas pipeline of central control module is provided with spark arrester; Centralized control module is provided with state detector, blows the electrical ball valve that grey back control air purges Impulsive tank and spout, and spout is provided with to detect and proofreaies and correct mouth and isolate air curtain apparatus.
Central control module is made up of gas supply device, air feeder, blender feeder on the spot.
Centralized control module is connected by electrical ball valve, magnetic valve, non-return valve, burning torch, state detector, air hose, mixing tube and forms.
The gas supply device is connected by gas inlet pipe, manual ball valve, spark arrester, mass flowmenter, electrical ball valve, Gas Pipe and forms.
The air feeder is connected and is formed by air intake duct, filter, distribution header, manual ball valve, Pressure gauge, mass flowmenter, electrical ball valve, air hose.
The blender feeder is connected by mixing chamber, Gas Pipe, air hose, mixing tube, pressure sensor, electrical ball valve and forms.
The air feeder of the utility model fuel gas energy-saving soot blower is often opened, and air insulated air curtain and heating surface be continuous service simultaneously.Can reduce leaking of Impulsive tank gaseous mixture, also can stop fluid to get into Impulsive tank through heating surface.
The utility model fuel gas energy-saving soot blower is when blowing ash, and the electrical ball valve Close All on the mixed pipe line of centralized control module when mixture pressure reaches certain value, begins the top-down ash that blows.Can make fuel gas and air reach best mixing like this, produce ultrasonic " shock wave ", avoid the waste of gaseous mixture.
Mouth is proofreaied and correct in detection through the utility model fuel gas energy-saving soot blower; Each spout be can test and intensity of wave and energy impacted; Dust stratification and slagging scorification situation according to heating surface are adjusted, and can carry out the periodicity correction to blowing grey intensity, avoid the waste of gaseous mixture.
The beneficial effect of the utility model is that province's moral ability has thoroughly solved fuel gas and air and lighted the uncertainty that produces ultrasonic " shock wave ".The utility model modularized design makes things convenient for the combustion gas soot blower to install and maintenance.
