The vertical type recoil filter is characterized in that the filter comprises a filter case, a filtering partition board, a mud accumulating tank, a recoil liquid inlet pipe, a spray head fixed carriage, a recoil liquid spray nozzle and a recoil liquid spray nozzle control device, the filtering partition board is perpendicularly arranged in the filter case, the mud accumulating tank is arranged at the bottom of the filter case, the recoil liquid inlet pipe penetrates into the side wall of the upper portion of a liquid inlet cavity of the filter case, and the spray head fixed carriage, the recoil liquid spray nozzle and the recoil liquid spray nozzle control device are located in the filter case. According to the vertical type recoil filter, the problems that the purification process tower body load is large, the washing efficiency is low and the cooling effect is reduced caused by the fact that a large amount of acid mud is contained in purification process acid water in the acid making system are solved, by means of a water curtain formed by recoil pipes, the acid mud deposited on filter plates and filter screens are subjected to back washing and discharged by the mud accumulating tank through a mud discharge port, and the efficiency for filtering the acid water is improved.
Description
Technical field
A kind of vertical backpulsing filter relates to a kind of filter of isolated by filtration pasty material, especially for the device that in the acid making system the sour mud in the diluted acid is filtered.
Background technology
Filter is widely used in acid making system, and as its name suggests, its effect is exactly to certain media filtration, makes it reach the purpose of clarification.Cleaning procedure is the key of dedusting in the acid making system, and it is being undertaken the removal of impurity in the flue gas and cooling, and the dopant species in the flue gas is various, mainly contains arsenic, dirt, fluorine, hydrogen chloride and hydrogen fluoride etc., and these magazine major parts are removed in cleaning system.If have arsenic in the flue gas, get into conversion system, can cause the poisoning of catalyst, cause the conversion system catalyst activity to reduce, conversion ratio descends; Carry a large amount of dirt in the flue gas, can influence dried desorption system finished acid and absorb sour qualification rate, form dirty acid, cause sour qualification rate to descend; Fluorine is brought dried desorption system into, can cause corrosion to the lining brick in the dry absorption tower, causes the umbrella of tower body to damage, and causes the corrosion to tower body.
At present, along with composition in the flue gas becomes increasingly complex, the dustiness in the flue gas strengthens, and causes the cleaning system load to strengthen, and sour mud increases.After containing more sour mud in the sour water, can cause tremendous influence to cleaning system.The shower nozzle of turbulent tower can be stopped up by sour mud, causes to purify the entrance flue gas temperature rising, and the operating load of pump also can strengthen.The deposition of acid mud has been aggravated the cooling-down effect of plate type heat exchanger greatly, because the continuous deposition of sour mud; Cause a large amount of sour dust in sour road in the plate type heat exchanger long-pending; It is not smooth to cause sour road to flow, and the heat exchange effect of influence and water channel causes cooling tower can not control flue-gas temperature; Two sections electric mist outlet temperatures raise, and influence the qualification rate of finished acid.
According to constantly groping, want to improve the cooling-down effect of cooling tower, reduce the washing cooling-down effect of sour mud to the cleaning system tower body, have only from the source and set about, promptly pump intake is carried out necessary sour mud and reduce behave, be the key that effectively guarantees the purifying and cooling washing.
Summary of the invention
The purpose of the utility model is exactly the deficiency that exists to above-mentioned prior art, a kind of convenience for washing is provided, the vertical backpulsing filter that filter efficiency is high.
A kind of vertical backpulsing filter is characterized in that its structure comprises:
Filter housings---this housing is the cavity housing that adopts the machine-shaping of fiberglass material; Be provided with inlet and liquid outlet relatively in the housing sidewall bottom;
Filter septum---this dividing plate is the hole pattern type filter of two block gaps, is vertically installed in the filter housings, and filter is divided into a feed liquor cavity, a fluid cavity;
The deposition groove---this crosses the deposition groove is to be arranged at bar-shaped trough on the going to the bottom of filter housings admission chamber side, recessed, and the bar-shaped trough bottom is provided with mud discharging tube;
Backwash liquid feed tube---this feed tube is that a level penetrates filter housings admission chamber upper portion side wall, bends downward vertically at filter housings, the acid-proof pipe of afterbody sealing; Be located at filter housings downward vertically the outside tube wall of bending part be provided with some sparge pipes;
Shower nozzle is balladeur train fixedly---this balladeur train for vertically be positioned at the filter housings admission chamber, near vertical bar frame filter septum, that have vertical bar shaped chute;
Backwash liquid nozzle---this backwash liquid nozzle is by can fixedly the horizontal jet pipe that slides up and down of the vertical bar shaped chute of balladeur train, the acid-resisting hose that is fixed on the nozzle of jet pipe head and is fixed on horizontal jet pipe afterbody are formed along shower nozzle; This acid-resisting hose is provided with some sparge pipes with the outside tube wall of backwash liquid feed tube and connects;
Fixedly form by acidproof rope, the upper end on the backwash liquid nozzle and the clutch that is positioned at the filter housings top by vertically penetrating roof on the filter housings, lower end for backwash liquid nozzle control device---this control device.
A kind of vertical backpulsing filter of the utility model is characterized in that between described filter septum, accompanying screen pack.
A kind of vertical backpulsing filter of the utility model, it is more effectively to adapt in the acid making system cleaning procedure sour water contained sour mud, causes cleaning procedure tower body load to strengthen; Detersive efficiency is low; The problem that cooling effect descends, the water curtain that relies on recoil tube to form carries out backwash to the sour mud that deposits on filter and the screen pack; Discharge through mud discharging mouth by the deposition groove then, improved filter efficiency sour water.
