Abstract
The invention provides a multi-grade filter. Gas purification equipment comprises a pot body, wherein an air inlet is arranged in the side wall of the lower part of the pot body; a drain outlet is arranged in the lower bottom end of the pot body; an upper annular separation plate and a lower annular separation plate are arranged at the lower part of the inner side of the pot body; the air inlet is communicated with a cavity between the upper annular separation plate and the lower annular separation plate; inner-layer and outer-layer vertical pipe bodies are arranged between the upper annular separation plate and the lower annular separation plate; the two ends of the inner-layer vertical pipe body are connected with end openings of inner rings of the upper annular separation plate and the lower annular separation plate; a baffle is arranged between the outer-layer vertical pipe body and the pot body; the baffle is arranged on one side of the air inlet and is tangent to the air inlet; the inner-layer vertical pipe body is provided with a gas channel; one baffle is arranged between the inner-layer and outer-layer vertical pipe bodies; the lower annular separation plate is provided with a through hole; the through hole is correspondingly arranged below a cavity between the inner-layer vertical pipe body and the outer-layer vertical pipe body; a stainless steel filtering net is arranged in the inner-layer vertical pipe body; and a filtering core is arranged above the upper annular separation plate. The filter has a good filtering effect and the clean grade of filtered gas is high.
Description
Technical field
The present invention relates to a kind of gas purifying equipment, particularly the filter plant in a kind of equipment of making nitrogen.
Background technology
Existing filter mostly is a tank body, and described tank body upper and lower part is provided with respectively gas outlet and air inlet, is provided with slide plate in tank body, is provided with filtrate at slide plate, the filter of this set, and when filtering gas, filter effect is relatively poor.
Summary of the invention
The invention provides a kind of filter, purpose is to solve the problem of existing pneumatic filter poor filtration effect.
The present invention includes tank body, the upper top of described tank body sets out gas port, on the lower sides of described tank body air inlet is set, lower bottom at described tank body arranges sewage draining exit, in described tank body lower inside toroidal membrane is set, lower toroidal membrane, on described, the edge of lower toroidal membrane is separately fixed on the madial wall of described tank body, described air inlet and described on, cavity between the lower toroidal membrane is communicated with, on described, in arranging between the lower toroidal membrane, outer two-layer vertical body, in described, the two ends of outer vertical body be separately fixed at described on, on the lower toroidal membrane, the two ends of the vertical body of described internal layer and described on, the interior central port of lower toroidal membrane is connected, in described, be provided with spacing between the outer vertical body, between the vertical body of described skin and described tank body, baffle plate is set, described baffle plate is arranged on a side of described air inlet and tangent with air inlet, on the vertical body of described internal layer gas passage is set, described gas passage is arranged on a side of described baffle plate and is separately positioned on the both sides of described baffle plate with described air inlet; Between the vertical body of described inside and outside layer, a baffle plate is set, described baffle plate and described gas passage are tangent, at described lower toroidal membrane through hole is set, described through hole correspondence is arranged on the cavity below between the vertical body of described internal layer and the vertical body of described skin; In described internal layer vertical line body, stainless steel filtering net is set, on described toroidal membrane above filter core is set.
When the present invention uses, in gas enters circular passage between the upper and lower toroidal membrane from air inlet, because the effect of baffle plate, gas can only take a round the passage expert, then enter the circular passage between the vertical baffle plate of the inside and outside layer of lower one deck, equally also because the effect of baffle plate, gas also takes a round the passage expert, and then the passage from the lower ring baffle flows out; Under the effect of centrifugal force, heavier water can be separated, and also the through hole from lower ring baffle flows out, and discharges through the sewage draining exit of lower end; The stainless steel filtering net of the dry gas of getting rid of in the vertical body of internal layer is by again once filtering, the last filter core of gas above process carries out third level filtration, and clean gas is discharged this filter good filtration effect finally by the gas outlet, the gas that filters, lustration class is high.
