Description
Affiliated technical field
The utility model relates to a kind of steam generator, especially automatically the antiscaling, descaling direct current cooker.
Background technology
At present, known direct current cooker is meant that the feedwater of boiler relies on pressure once-through in heating surface of feed pump to produce the steam generation boiler of steam.This boiler is made up of feed pump, spiral tube heating surface (dividing radiation heating-surface and convection heating surface), burner and water controller.This boiler extracts hydraulic pressure by feed pump and goes into the spiral tube heating surface from water tank, spiral tube is at burner hearth and convection part is accepted fuel and air mixing after-combustion flame radiation is hot and the once pre-thermal evaporation of advection heat quilt is heated into steam, discharges from the stop valve of upper boiler.This boiler does not have jumbo drum and water drum, does not need to collect case yet.Its water capacity is generally all smaller, and the danger of its blast is also smaller, almost can ignore.Just owing to this, direct current cooker is very high to requirements in water quality, and well-known, the calcium that contains in the former water, magnesium ion composition have certain rigidity, be condensed on the evaporation tube in boiler into incrustation scale attached on the pipe inner wall, its result can cause water pipe heat transfer severe exacerbation.On the other hand, the thermal conductivity factor of incrustation scale only is 1/40～1/50 of an evaporation tube metal material, tube wall causes that because of adhering to incrustation scale the evaporation tube temperature rises, and the heat by tube wall will reduce, and surpasses the allowable temperature of material when the temperature of tube wall, the strength of materials will reduce, cause water pipe dilatancy even booster, not only cause the waste of boiler thermal output reduction and fuel, and water pipe booster rear furnace body is not easy maintenance, often need to change, thereby result in greater loss.Therefore all these type of boilers all are equipped with demineralizing plant both at home and abroad, and the hardness ions concentration of stove water is detected, and force to make the boiler periodical blowdown, regularly clean.Operation easier and operating cost have been increased.
Summary of the invention
In order to overcome the deficiency that existing direct current cooker is very high to water quality requirement, must set up hydrotreater, reduce the boiler acquisition cost, increase the boiler operatiopn effect, reduce operating cost, the utility model provides a kind of automatic desludging direct current cooker, and this direct current cooker can make things convenient for automatic desludging, keep the evaporation tube inwall clean, do not retain incrustation scale, water quality is not required, thereby need not to be provided with water treatment facilities and water quality is detected.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of automatic desludging antiscale direct current cooker, by feed pump, heat pipe spirals, burner and water controller are formed, the liquid-solid separating dispenser of installing one cover between the water inlet of the heat pipe that spirals of direct current cooker and venthole, this liquid-solid separating dispenser is made of separate and subside chamber and diversion chamber, top, separate and subside chamber is hollow cylinder, the bottom is a hollow cone, on, be connected between the bottom, at the top of separate and subside chamber the clear water output pipe is housed, the clear water output pipe is connected with the boiler gas outlet, fluid inlet tubes is equipped with on top in the separate and subside chamber, fluid inlet tubes is connected with the heat pipe gas outlet of spiraling, in the bottom of separate and subside chamber the particle control valve is housed, diversion chamber is a hollow cylinder body structure, its inside is provided with the baffle of a band tapering, at the top of diversion chamber the particle inlet tube is housed, the particle inlet tube is connected with the particle control valve outlet of bottom, separate and subside chamber, at other clear water inlet tube and the fluid-mixing outlet of also being equipped with respectively of the side of diversion chamber, the clear water inlet tube is connected with the feed pump outlet, the fluid-mixing outlet is connected with the heat pipe water inlet that spirals, blow-off pipe is equipped with in bottom in diversion chamber, and blow-off pipe is connected with a stop valve.
Boiler feed pump extracts water from water tank, at first enter the inlet port of liquid-solid separating dispenser bottom, because hydraulic action, the solids of liquid-solid separating dispenser inside are pressed into continuously the water inlet of the heat pipe that spirals from the outlet of liquid-solid separating dispenser bottom, flow along the spiral tube inwall, enter into the import on liquid-solid separating dispenser top from the outlet of spiral tube, because the change of flow direction and slowing down of speed, make solids different because of proportion with water, in liquid-solid separating dispenser, separate, water flows out from the delivery port on liquid-solid separating dispenser top, solids are deposited in the inside of liquid-solid separating dispenser and are deposited to its bottom and mix with the current that the bottom water inlet enters because of gravitational settling, are pressed into the water inlet of spiral tube with water, so go round and begin again, constantly circulation.
The know-why that the utility model technical solution problem is adopted is:
In the heat pipe that spirals, the solids of configuration certain particle size and volumetric concentration, in the certain flow scope under the drive of water, particle is mobile in pipe with the water of motion in pipe, solids constantly collide with inside pipe wall, thereby reach automatic cleaning and descaling, antiscale purpose.This device has two effects, and the one, the water that comes out from the spiral tube venthole and the fluid-mixing of solids are carried out liquid-solid the separation, solids are collected.The 2nd, the particle of collecting is sent into spiral tube again by water inlet.
The beneficial effects of the utility model are: can clean the inwall of the heat pipe that spirals of direct current cooker automatically, avoid inwall to produce incrustation scale, keep the efficient heat transfer effect of heat pipe, thereby reach the purpose that cuts down the consumption of energy.
