Description
Technical field
The utility model relates to wet electric cleaner technical field, refers in particular to a kind of sealing pressure release explosion venting device.
Background technology
Along with the development of society and the progress of the mankind, people more and more pay attention to quality of life and own health, and also more and more pay close attention to ecological environment and air quality, atmosphere pollutants emission standards is also more and more stricter.Wet method fume desulfurizing system does not almost remove the ability of PM2.5 particle, to mercury and SO
3removing of aerosol etc. is also very limited, causes chimney often to occur the phenomenon such as " blue smoke ", " acid rain ", " gypsum rain ", serious environment pollution, and harm humans is healthy.
Wet electric cleaner is exactly arise at the historic moment in such a case, can realize minimum discharge, control PM2.5 concentration.At present the range of application of wet electric cleaner is more and more extensive, and containing explosion hazard gases in the waste gas that some occasion produces as pneumatic steelmaking, except taking necessary explosion precaution, installation pressure release explosion venting device is also one of effective means.Explosion venting device is in the market made up of framework and venting of dust explosion diaphragm, but if run into containing corrosive gas and water capacity is larger when, near explosion venting device, flue gas can condense thus cause its seriously corroded, affects the venting of dust explosion precision of explosion venting device.Sometimes also exist because deduster bulk density increases suddenly the venting of dust explosion that explosion venting device may produce mistake.Cause the waste of explosion venting device, and it is large to there is manufacture difficulty, the problem that cost is high.
Summary of the invention
For above problem, the utility model provides a kind of sealing pressure release explosion venting device, and it can not only reach the pressure release venting of dust explosion of wet electric cleaner, and has anti-corrosive properties, can also reduce the quick-fried probability of mistake of explosion venting device, and its structure is simple, easy to make, low cost and other advantages.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of sealing pressure release explosion venting device, comprise the gate seat that pressing plate, guide blot, door closure, strip steel spring and employing anticorrosive property material are made, gate seat is corresponding with door closure to be connected, strip steel spring top contacts at bottom pressing plate, contact at door closure top bottom strip steel spring, pressing plate, door closure, gate seat are corresponding with guide blot respectively to be arranged.
Further, be provided with spacing block set bottom pressing plate, strip steel spring is sheathed on spacing block set skin.
Further, door closure top is provided with spacing recessed piece, and spacing recessed piece is provided with groove, and strip steel spring coordinates to be located in groove.
Further, guide blot top is through at pressing plate and is fixed by band sleeve nut, and be provided with packing ring between band sleeve nut and pressing plate, guide blot bottom is through at door closure and is fixed on gate seat.
Further, door closure is connected on gate seat by sealing gasket, and sealing gasket is embedded on gate seat.
The beneficial effects of the utility model:
The utility model can not only reach the pressure release venting of dust explosion of wet electric cleaner, can adapt to again containing appropriate height and there is corrosive environment and do not produce corrosion, the quick-fried probability of mistake of explosion venting device can also be reduced, and its structure is simple, easy to make, there is the using function of manhole door, to automatically reset performance by strip steel spring after pressure release, Reusability, cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
In figure: 1, be with sleeve nut; 2, packing ring; 3, pressing plate; 4, guide blot; 5, door closure; 6, sealing gasket; 7, gate seat; 8, strip steel spring; 9, spacing block set; 10, spacing recessed piece.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the technical solution of the utility model is described.
As shown in Figure 1, one sealing pressure release explosion venting device described in the utility model, comprise pressing plate 3, guide blot 4, door closure 5, strip steel spring 8 and the gate seat 7 adopting anticorrosive property material to make, gate seat 7 is corresponding with door closure 5 to be connected, strip steel spring 8 top contacts at bottom pressing plate 3, contact at door closure 5 top bottom strip steel spring 8, pressing plate 3, door closure 5, gate seat 7 are corresponding with guide blot 4 respectively to be arranged.
The above forms the utility model basic structure.
Gate seat 7 described in the utility model is fixedly connected with the outer wall of wet electric cleaner.
Utility model works principle: when the internal pressure of wet electric cleaner exceedes setting value, door closure 5 is because inside pressure is greater than outside pressure and can produces pressure to strip steel spring 8, thus door closure 5 moves along guide blot 4 to pressing plate 3 direction, door closure 5 and gate seat 7 are departed from, thus reach the object of venting of dust explosion, after pressure release venting of dust explosion, automatically recover its sealing property by the bounce of strip steel spring 8, can Reusability, save cost.
Be provided with spacing block set 9 bottom pressing plate 3 described in the utility model, strip steel spring 8 is sheathed on spacing block set 9 skin.When adopting such vibrational power flow to prevent pressurized by spacing block set 9, strip steel spring 8 produces displacement.
Door closure 5 top described in the utility model is provided with spacing recessed piece 10, and spacing recessed piece 10 is provided with groove, and strip steel spring 8 coordinates to be located in groove.When adopting such vibrational power flow to prevent pressurized by spacing recessed piece 10, strip steel spring 8 produces displacement.
Guide blot 4 top described in the utility model is through at pressing plate 3 and is fixed by band sleeve nut 1, and be provided with packing ring 2 between band sleeve nut 1 and pressing plate 3, guide blot 4 bottom is through at door closure 5 and is fixed on gate seat 7.When the internal pressure of wet electric cleaner exceedes setting value, door closure 5 moves along guide blot 4 to pressing plate 3 direction, door closure 5 and gate seat 7 is departed from, reaches the object of pressure release venting of dust explosion.
Door closure 5 described in the utility model is connected on gate seat 7 by sealing gasket 6, and sealing gasket 6 is embedded on gate seat 7.Can make to be tightly connected between door closure 5 and gate seat 7 by sealing gasket 6.
Be more than the utility model preferably embodiment, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to above-mentioned detailed description of the invention, and any apparent improvement that every those skilled in the art do on basis of the present utility model, replacement or modification all belong to protection domain of the present utility model.
