Description
Technical field
The utility model belongs to the heat explosion pulse ash-blowing technical field, is specifically related to a kind of dual complete explosion and leakage prevention distribution apparatus.
Background technology
Heat exploding pulse sootblower is called for short pulse soot blower, have another name called the shock-wave ash blowing device, the shock wave soot blower, weak quick-fried soot blower, blast wave blower, the detonation wave soot blower, pinking pulse soot blower etc., the earliest by the people of former Soviet Union utility model, imported China in 1988 into, develop by " gas big gun ", its basic principle of blowing ash is: the gaseous mixture that makes fuel and oxidant gas with impulse generator that flue is communicated with in light a fire and explode, utilize " the alternation punching press is inhaled and drawn effect " of the compression shock ripple of blast generation, " the purging effect " of " physics effect of micro-explosion " and high-speed pulse jet blown down the various dust stratifications on boiler heating surface and the flue wall, has vibration simultaneously concurrently, three kinds of deashing effects of sound wave and high temperature pyrolysis.Impulse generator claims shock wave generator, surge generator, blast wave generator, detonation wave generator, blast jar, Impulsive tank etc. again; Impulse generator can directly be communicated with flue, also can be communicated with flue by pulse conduit, and pulse conduit claims transmitting tube, jet pipe etc. again.Because belonging to dry type blows ash, and blow that grey intensity height, no dead angle, sphere of action are big, good energy-conserving effect, equipment dependability height, to blow grey expense cheap, has impayable superiority with traditional steam soot blowing ratio, not only be used for heated surface at the end of boiler at large and replaced traditional steam soot blowing, and begin to be used to blow down industrial furnace interior dust stratification and slagging scorification, even also attempted being used for other occasions such as auxiliary deashing of electrostatic precipitator.
Heat exploding pulse sootblower includes air distributing device mostly, and air distributing device mainly comprises fuel conduit and oxidant gas pipeline, is serially connected with fuel cock valve and oxidant gas switch valve on fuel conduit and oxidant gas pipeline respectively; Generally also be serially connected with non-return valve, spark arrester etc. on fuel conduit, what have also is serially connected with non-return valve and/or spark arrester on the oxidant pipeline; Most of air distributing devices also comprise the gaseous mixture pipeline, generally also are serially connected with blender on the gaseous mixture pipeline; Air distributing device generally also comprises priming supply and lights a fire first-class.
Existing pulse soot blower has only the fuel magnetic valve to adopt the explosion-proof type magnetic valve mostly, and other Charging system and parts then lack explosion precaution.
The air distributing device of existing heat exploding pulse sootblower has two kinds: a kind of is exposed fully, and another kind then is contained in the metal cabinet, and is no matter any, and its anti-leak performance is all relatively poor.
The utility model content
The purpose of this utility model is: a kind of dual complete explosion and leakage prevention distribution apparatus is provided, and with the prior art ratio, its explosion and leakage prevention performance is better.
Scheme of the present utility model is: dual complete explosion and leakage prevention distribution apparatus, mainly comprise housing, fuel conduit and oxidant gas pipeline, on fuel conduit, be serially connected with electronic fuel cock valve, be serially connected with electronic oxidant gas switch valve on the oxidant gas pipeline, part of fuel pipeline and the electronic fuel cock valve that upward is connected in series thereof and partial oxidation agent gas piping and the electronic oxidant gas switch valve that upward is connected in series thereof are insulated material and cast in the housing.
The insulating materials and the housing of casting can both shield the electric spark of all live parts that cast in the insulating materials, thereby have better explosion-proof performance; The insulating materials of casting and housing also can both avoid fuel or oxidant gas to see through screw thread on the pipeline or flange-interface to external leakage, thereby have better anti-leak performance.
Major advantage of the present utility model is as follows:
1. have housing and the dual explosion precaution of casting, thereby have fabulous explosion-proof performance;
2. have housing and the dual containment measures of casting, thereby have fabulous anti-leak performance;
3. owing to have housing and the dual explosion and leakage prevention measure of casting, security is greatly enhanced;
4. because electronic fuel cock valve and electronic oxidant gas switch valve all cast in the insulating materials, its vibration resistance has also obtained increasing substantially.
Described housing is closure casing preferably, can have cap on the housing, and the material of housing is metal material preferably, can be carbon steel, stainless steel, also can be aluminium alloy or magnesium alloy material.
Be serially connected on the fuel conduit and cast in and spark arrester and non-return valve can also be arranged in the housing.
Be serially connected on the oxidant gas pipeline and cast in and also spark arrester and non-return valve can be arranged in the housing.
Described electronic fuel cock valve and electronic oxidant gas switch valve can be magnetic valves, also can be electrical ball valves.
Cast in and can also comprise blender, temperature sensor, blast monitor, relay, control device, priming supply and igniter head in the housing, igniter head can be arranged on blender or the mixed pipe line.
