Abstract
The utility model relates to a decompression device used in a water coal gasification grey water treating device, in particular to a decompression valve for treating grading gasification furnace dust water, solving the problem that a baffling decompression valve used in the treatment of the grading gasification furnace dust water is easy to be scoured and damaged in the prior art. The structure of the decompression device comprises a decompression valve directly connected with pipes; a decompression stilling chamber connected with a vacuum flash vaporization can is arranged at the other end of the decompression valve, a limiting current pore plate is arranged in the decompression buffering chamber. Compared with the prior art, a designed proposal is adopted that high-pressure grey water is sent into a decompression buffering zoon by the decompression valve, and after the pressure of the water is reduced, and the pressure of the grey water is reduced again by the limiting current pore plate, thus leading the decompression mode of <high pressure-low pressure> to be changed into the mode of <high pressure-middle pressure-low pressure> and causing the pressure of the grey water to be lowered to the needed pressure, and effectively reducing the abrasion of the decompression valve and greatly improving the running time of the grey water treating device; the stream efficiency of the device is improved to above 98 percent.
Description
Technical field
The utility model relates to the reliever that uses in a kind of water-gas ashing water treating equipment, is specially a kind of graded gasification furnace grey water handing pressure loading valve.
Background technology
The cleaning of coal and efficient utilization are the great technical tasks in current China energy and environment protection field, also are one of gordian techniquies of Chinese national economy sustainable development.Gasification is the main path that primary energy source is converted into clean secondary energy, and its product is fuel gas (coal gas), synthetic gas, reducing gas, hydrogen, carbon monoxide.The coal gasification technology has obtained using widely in the production of combined cycle (IGCC) power generation assembly, synthetic ammonia and synthesizing methanol industry, producing acetic acid by carbonylation method and acid anhydrides industry, sponge iron, the fields such as preparation of pure carbon monoxide, and nitrogen fertilizer production sewage zero-discharge engineering is the special pollution treatment project of nitrogenous fertilizer industry of State Environmental Protection Administration's popularization.Environmental protection problem more and more has been subjected to attracting attention of the whole world, how to realize the reasonable utilization of closed circuit water cycle of fertilizer industry and water resources, is the cleaning and the efficient subject matter of utilizing that is related to coal.
At present, in the technology that adopts entrained flow gasification, the processing of buck has become the subject matter that influences the device long-term operation, and it shows as the wearing and tearing of grey water treatment system and the fouling of pipeline is stopped up; Particular case is that the Heisui River that Heisui River of discharging from the graded gasification furnace shock chamber and synthesis gas washing tower bottom are discharged is driven an expenditure and pressure valve that is equipped with by pipeline separately by one respectively and entered hp flash drum.High-temp liquid is rapid depressurization behind reducing valve, and hp flash drum working pressure 0.5MPa (G) is the gaseous phase outlet pressure regulator valve control of dodging separator by high.Through the high-temp liquid behind the reducing valve, rapid depressurization behind valve, the directly inner flash distillation of access arrangement then, because high-temp liquid is from the 3.5MPa 0.5MPa that directly reduces pressure, moment of pressure reduces and makes the Heisui River flow velocity increase several times, causes directly the washing away of equipment, and has reduced the work-ing life of equipment.
Summary of the invention
The utility model is provided a kind of graded gasification furnace grey water handing pressure loading valve by the problem of erosion damage easily in order to solve the expenditure and pressure valve that uses in the graded gasification furnace grey water handing that exists in the prior art.
The utility model is realized by following technical scheme, a kind of graded gasification furnace grey water handing pressure loading valve, comprise with directly and the reducing valve of pipe connection, be provided with and the tank connected step-down surge chamber of vacuum flashing at the other end of reducing valve, be provided with restriction orifice in the step-down surge chamber.
The outlet of reducing valve has increased restriction orifice, forms a step-down buffer zone behind valve, directly washing away of equipment is changed high-temp liquid into pressure reduction with classification twice, and at first decompression enters the step-down buffer zone through reducing valve, carries out the one-level decompression; Next through restriction orifice access arrangement inside, carries out second depressurized from the step-down buffer zone.Following advantage is arranged: 1, reduced the pressure drop of reducing valve front and back, made the Working environment gentleness of reducing valve, prolonged its work-ing life.2, the increase of restriction orifice has reduced the pressure drop of Heisui River access arrangement behind the reducing valve again, and the flow velocity in the Heisui River of having slowed down has reduced high temperature Heisui River washing away equipment.
Aperture on the restriction orifice again uniform distribution Heisui River, make Heisui River on whole orifice plate, carry out flash distillation, increased the distribution area of flashed liquid, the flash efficiency of flash tank is increased substantially, and has obtained good operating performance.
Compared with prior art, the utility model adopts and by reducing valve the high pressure buck is sent into the pressure-reducing cushioning district, reduce the back in the design that reduces grey water pressure by restriction orifice once more at buffer zone pressure, make pressure reducing mode become " high pressure---middle pressure---low pressure " by " high pressure---low pressure ", make grey water pressure be reduced to required pressure, effectively reduced the wearing and tearing of reducing valve, improved the working time of grey water handing device greatly, the working rate of device is brought up to more than 98%.
