A kind of rock wool production line tail gas filtering room
Technical field
This utility model relates to a kind of rock wool tail gas treatment device field, specifically a kind of rock wool production line tail gas filtering room.
Background technology
In rock wool production process, no matter it is all contain rock wool fibers from cotton collecting machine or from the tail gas that curing oven is discharged, resin, the foreign material such as broken cotton or slag ball, in order to meet environmental requirement, need could discharge after filter chamber filters, existing filter chamber screen plate adopts rock cotton board, tail gas blows to the upper surface of rock cotton board from top to bottom and forms negative pressure wind, the fiber being mingled with inside negative pressure wind, the foreign material such as slag ball are easy to blocking rock cotton board, and air inlet mode from top to bottom allows foreign material directly fall on the upper surface of screen plate, easily cause rock cotton board obstructed, need artificial timing cleaning, waste time and energy and affect the normal of rock cotton board and produce;The life cycle of rock cotton board is very short simultaneously, it is necessary to be periodically subject to change, and the filtration cost and the replacing environment that improve tail gas are poor, change inconvenience.
Summary of the invention
In order to overcome drawbacks described above, this utility model provides a kind of rock wool production line tail gas filtering room, tail gas filtering direction no longer directly blows to the upper surface of screen plate from top to bottom, but blow to the lower surface of screen plate from the bottom up, foreign material can be attached to the lower surface of screen plate under gravity, no longer easily it is directly entered in screen plate and be not susceptible to clogging, extend the life cycle of screen plate.
The technical solution adopted in the utility model is: arranges lower air inlet 1 bottom the sidepiece of this filter chamber and arranges air outlet 2 at its top the direction away from lower air inlet 1, air outlet 2 connects the air exhauster being arranged on outside filter chamber, horizontal lower support frame 4 is laid at the interval, top of filter chamber, transversely bracing frame 5 are laid on the top of each adjacent transverse lower support frame 4, transversely the two ends of lower support frame are respectively arranged with the connection with filter chamber, at horizontal lower support frame 4 and transversely overlap the defecator with screen plate between bracing frame 5.
The lower air inlet of this filter chamber connects the tail gas needing to filter, simultaneously under the effect of air exhauster 7, foreign material in tail gas constantly waft from lower to upper to the lower surface of screen plate and are attached to its lower surface, under foreign material self gravitation effect, a large amount of foreign material no longer directly pierce the inside of screen plate, extend the life cycle of screen plate;Simultaneously because devise horizontal lower support frame 4, by by this bracing frame, in that context it may be convenient to change the screen plate in defecator, the replacing enhanced convenience of screen plate.
This utility model devises, described defecator includes the screen plate 6 being arranged in pairs, the upper end of each screen plate 6 is overlapped on the end of transversely bracing frame 5, with the end that its lower end is overlapped on horizontal lower support frame 4, angled distribution between every pair of screen plate 6, the upper surface at each screen plate 6 lays grid cloth 7.
This utility model devises, and arranges nozzle 8 in the horizontal on bracing frame 5, arranges Pressure gauge 9 on the pipeline of upper air outlet 2.
This utility model devises, and described screen plate 6 adopts rock cotton board.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
In conjunction with accompanying drawing, the utility model will be further described, Fig. 1 is a kind of embodiment of the present utility model, lower air inlet 1 is set bottom the sidepiece of this filter chamber and air outlet 2 is set at its top the direction away from lower air inlet 1, air outlet 2 connects the air exhauster being arranged on outside filter chamber, horizontal lower support frame 4 is laid at the interval, top of filter chamber, transversely bracing frame 5 are laid on the top of each adjacent transverse lower support frame 4, transversely the two ends of lower support frame are respectively arranged with the connection with filter chamber, also include the screen plate 6 being arranged in pairs, the upper end of each screen plate 6 is overlapped on the end of transversely bracing frame 5, with the end that its lower end is overlapped on horizontal lower support frame 4, angled distribution between every pair of screen plate 6, upper surface at each screen plate 6 lays grid cloth 7, in the horizontal bracing frame 5 arranges nozzle 8, the pipeline of upper air outlet 2 arranges Pressure gauge 9.
Under the effect of air exhauster 3, wind direction is from lower to upper, tail gas first passes through grid 7 and is blocked in outside it by a large amount of rock wool fibers and bulky grain slag ball, or be deposited on grid cloth or fall bottom filter chamber, tail gas impurity content after grid cloth 7 pre-filtering greatly reduces, discharge by air outlet then through after rock wool screen plate secondary filter, when screen plate 6 blocks comparatively serious, screen plate 6 top is filtered room pressure and is reduced, when reducing to certain value, Pressure gauge 9 one aspect can pass through external sensor automatic alarm, the nozzle 8 on screen plate top can be automatically opened up on the other hand, flushed filter plate.
In this example, described screen plate 6 adopts rock cotton board, and rock cotton board use cost is relatively low.
Horizontal lower support frame 4 also as access path, can facilitate maintainer to change screen plate.When having a large amount of rock wool fibers and slag ball bottom filter chamber, operator can use loader to clear up, convenient and swift.
