Description
Technical field
The present invention relates to a kind of magnetic force and sweep dirt water spraying steam generating plant.
Background technology
Boiler is extremely important thermal power parts, owing to boiler produces saturated steam by heating water, utilize the saturated vapor with certain pressure to realize transmission ofenergy and transfer, finish the work so boiler needs to evaporate a large amount of water, belong to High Temperature High Pressure special equipment, therefore also face important, the most serious problem, prevent the cleaning of fouling and incrustation scale exactly.
Present stage, the cleaning of incrustation scale generally relies on and manually carries out, also it is exactly that people is entered in boiler cavity by boiler manhole and clears up, but intensity is very big, and consuming time, effort, impact are produced, always there is corrosion boiler steel in soak cleaning, affecting the safety worries that boiler is pressed, taking precautions against fouling so general is exactly water softening process, but appoints, owing to there are problems, the generation that so cannot stop fouling completely, just there is boiler efficiency once fouling to reduce, also there are the problems such as boiler safety hidden danger.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, it is provided that a kind of simple and practical, low cost, the magnetic force being convenient to implement sweep dirt water spraying steam generating plant.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of magnetic force sweeps dirt water spraying steam generating plant, comprise pot cylinder, left and right header, high-order fire tube, low position fire tube, fall circulation tube and water circulation tank under water, it is characterized in that: fall circulation tube under water and connect pot cylinder and header, between pot cylinder and header, also it is provided with high-order fire tube and low position fire tube; Water circulation tank is through water pump connecting tee stopcock, and threeway plug valve, through the blow-off pipe at pipeline communication header two ends, is connected with below blow-off pipe and drives wash water valve soon, and the blow-off pipe at header two ends connects through pipeline and returns to water circulation tank after another threeway plug valve; The nozzle of water circulation tank in water pump and pipeline communication pot cylinder, also it is provided with by the molecular hydro powered magnetic piston traction scoop cleaning plant of stainless steel tube, magnetic piston, steel bushing, hinge and shovel in pot cylinder, stainless steel tube two ends are all connected with water valve and water discharge valve, magnetic piston can flexible motion in stainless steel tube, steel bushing can be driven mobile flexibly by magnetic piston outside being enclosed within stainless steel tube, steel bushing moves about driving scoop by hinge, and scoop shape matches with boiler drum bottom; Boiler drum bottom is provided with that blowdown is curved and blowdown interface, and blowdown is curved and establishes below blowdown interface and drives wash water valve soon.
In described water circulation tank, the pump mouth of water pump is provided with filter screen, both can filter out the dregs in pond, also can avoid damaging water pump.
Described opening soon is connected with blow-off pipe below wash water valve.
The blowdown of described boiler drum bottom is curved returns to water circulation tank with blowdown interface through pipeline and valve.
Boiler pressure and water circulation system generally by pot cylinder, fall circulation tube under water and also have left and right header to form with many group fire tubes, during normal operation of boiler, water level is full of pot cylinder 80% volume substantially, and strong firepower direct heating face is lower half and the fire tube of pot cylinder; Fall circulation tube under water both to play a supportive role, it it is again the key part connecting pot cylinder and header, do not heat by firepower, strong firepower direct heating boiler drum bottom, heat power drives hydro-thermal power convection circulation in pot cylinder, and the direct-fired fire tube of strong firepower is pipe internal water heat temperature raising under strong firepower effect, and density reduces, produce heat power upwelling, fall the decline of circulation in-pipe flow under water and form complete water circulation path by left and right header again. Boiler is once fouling comes off will be deposited in boiler drum bottom and left and right header, and thus boiler drum bottom and left and right header are the key positions of cleaning incrustation scale.
Cleaning to incrustation scale in pot cylinder: pot cylinder waterpower, magnetic force cleaning core component is exactly hydro powered magnetic piston traction scoop, magnetic piston can flexible motion in stainless steel tube, steel bushing can be driven mobile flexibly by magnetic piston outside being enclosed within stainless steel tube, steel bushing moves about driving scoop by hinge, scoop shape is to coordinate boiler drum bottom as the best, when right-hand member water valve and left end water discharge valve are opened, water enters right-hand member driven plunger by right-hand member water valve and drives scoop to go back to position to left end, close right-hand member water valve and left end water discharge valve again, open left end water valve and right-hand member water discharge valve, water enters stainless steel tube left end driven plunger by left end water valve and drives scoop to move to pot cylinder right-hand member to right-hand member shovel deposition incrustation scale, simultaneously high velocity flow is sprayed into pot cylinder by water pump and carries out sweeping stream by water cycle pool inner water after filtering, scoop is coordinated to carry heavy dirt motion of catchmenting to pot cylinder rear portion, simultaneously nozzle can remove the corner or spot as yet untouched by a clean-up campaign of the most left end of pot cylinder,, pot cylinder blowdown interface curved by pot cylinder blowdown flow to and opens sewage draining valve top soon again, both can arrange outward and also can enter water circulation tank and carry out incrustation scale sedimentation. blowdown interface can make the rear portion blowdown of pot cylinder take the enhancing of incrustation scale ability out of, does not affect pot cylinder by power and carrying simultaneously.
Cleaning to incrustation scale in header: coordinated with water pump, pipeline by two threeway plug valves and realize positive and negative water cleanses.
Just washing and it is being achieved in that water cycle pool inner water enters header anteposition blow-off pipe to the left by water pump suction threeway plug valve after filtration and rises through header as the first cleaning technology, after header, position blow-off pipe and another threeway plug valve flow back to water circulation tank, realize carrying from left to right to discharge by incrustation scale in header in circulation pond, carry out settlement treatment, or by opening wash water valve directly outer row soon.
Backwash as the 2nd cleaning technology with just wash just contrary: after water cycle pool inner water enters header to the right by water pump suction threeway plug valve after filtration, position blow-off pipe rises through header, water circulation tank is flowed back to through header anteposition blow-off pipe and another threeway plug valve, realize carrying from right to left to discharge by incrustation scale in header in circulation pond, carry out settlement treatment, or by opening wash water valve directly outer row soon.
Compared with prior art, the useful effect of the present invention is also:
Utilizing current spray to wash coordinates waterpower magnetic force driving scoop that boiler drum bottom and header realize convenient thorough cleaning incrustation scale, does not need people to enter in pot cylinder, also need not open any parts and can realize pure physical cleaning, not cause chemical agent to injure in boiler; Structure is simple, strong operability, utilizes the component of boiler itself to realize the convenient cleaning of incrustation scale to greatest extent, and can realize not shutting down in good time cleaning; Utilize three-way tap to realize positive backwash cleverly, not only make cleaning work more convenient, thorough, and save a lot of valve, have a extensive future.
