Meanwhile, a sludge accumulation groove with a sludge discharging opening is arranged at the bottom of the filter so that the working staff can conveniently discharge the sludge and labor intensity is reduced.

Description

A kind of filter

Technical field

A kind of filter relates to a kind of filter of metallurgy chemical process, the device that the sour mud in the diluted acid is filtered especially for the cleaning system in the relieving haperacidity process.

Background technology

Filter is widely used in metallurgy chemical process.As its name suggests, its effect is exactly to certain media filtration, makes it reach the purpose of clarification.

In soft water system, the automatic immersion type filter is installed, be used for new water is filtered, remove impurity wherein, for the ion-exchanger operate as normal provides safeguard.

The cleaning procedure of relieving haperacidity process is the key of dedusting in the acid making system; It is being undertaken the removal of impurity in the flue gas and cooling; 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 this utility model Jie of the above prior art shortcomings, provide an easy to clean, high filtration efficiency of the filter.

The purpose of the utility model realizes through following technical scheme.

A kind of filter is characterized in that its structure comprises:

Filter housing, this housing are a horizontal tubular shell, are provided with feed pipe at housing one side lower part, and opposite side top is provided with drain pipe;

Filter, this filter vertical center is arranged in the filter housing, and filter filter housing is divided into two cavitys, and one is the pug chamber, and one is the clear liquid chamber;

Deposition groove, this deposition groove be located at filter housing pug chamber, near the groove on the filter housing of filter, at the bottom of groove, be provided with mud discharging mouth;

The clear mud pipe of filter, the clear mud Guan Weiyi of this filter right angle folding pipe; Horizontal tube one end of folding pipe passes the filter housing vertically and connects with suction pump, and other end termination passes pug chamber that filter plate is positioned at the filter filter, roll over the right angle with combining as a whole and manage vertical tube and connect; Near filter plate face, and have vertical bar shaped mud-suction hole on the tube wall near filter plate face one side on the vertical tube;

The clear mud pipe of filter driving shaft, this driving shaft are one coaxial with the filter housing, that an end connects with the clear mud pipe of filter, the other end passes filter filter pug chamber end sidewall, connect with drive unit.

A kind of filter of the utility model is characterized in that described filter is added with forming of tetrafluoro filter medium by the centre of two hole pattern filters and two hole pattern filters.

A kind of filter of the utility model can clean the sour mud on the dividing plate effectively through the clear mud pipe of filter, has guaranteed the filter effect of dividing plate.Simultaneously,, greatly facilitate the worker it is carried out spoil disposal work, alleviated labour intensity because its bottom is provided with the deposition groove that has mud discharging mouth.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment,

A kind of filter, its structure comprises: filter housing 1, this housing are a horizontal tubular shell, are provided with feed pipe 2 at housing one side lower part, and opposite side top is provided with drain pipe 3; Filter 4, this filter vertical center is arranged in the filter housing, and filter filter housing is divided into two cavitys, and one is that 5, one in pug chamber is clear liquid chamber 6; Deposition groove 7, this deposition groove be located at filter housing pug chamber, near the groove on the filter housing of filter, at the bottom of groove, be provided with mud discharging mouth 8; The clear mud pipe 9 of filter, the clear mud Guan Weiyi of this filter right angle folding pipe; Horizontal tube one end of folding pipe passes filter clear liquid chamber end housing body sidewall vertically and connects with suction pump 10, and other end termination is passed filter plate, is positioned at the pug chamber of filter filter, is connected with the vertical tube of right angle folding pipe with combining as a whole; Near filter plate face, and have mud-suction hole on the tube wall near filter plate face one side on its vertical tube; The clear mud pipe of filter driving shaft 11, this driving shaft are one coaxial with the filter housing, that an end connects with the clear mud pipe of filter, the other end passes filter filter pug chamber end sidewall, connect with drive unit 12.

A kind of filter of the utility model, described filter is added with forming of tetrafluoro filter medium by the centre of two hole pattern filters and two hole pattern filters.

A kind of filter of the utility model; During ordinary production, filter feed liquid and get into the filter housing, filter through filter through charging aperture; Acid mud is filtered plate and holds back entering deposition groove; Discharge through mud discharging mouth, liquid gets into the clear liquid chamber through filter and is discharged by drain pipe, accomplishes filter process; Blocked up when the deposition of filter mud layer, when pug chamber and clear liquid cavity pressure do not wait, make the clear mud pipe of filter drive shaft turns through starting drive unit; And then the clear mud pipe of drive filter rotates; Open suction pump, the deposition of filter mud layer goes out filter through the bar shaped mud-suction hole sucking-off on the clear mud pipe of filter by pumping; Accomplish the cleaning that filter filters, carry out the normal filtration operation again.
