Abstract

A dry micropore-filtering duster is composed of top cover, the upper and middle case bodies, dust hopper and its supporter, dust discharging valve under dust hopper, the patterned plate with the uniformly arranged circular holes between upper and middle case bodies, and the micropore filtering ceramic tubes for said circular holes on patterned plate. It has high dusting effect and high mechanical strength.

Description

Dry type micro porous filtration deduster
Technical field
The present invention relates to a kind of dry type micro porous filtration and remove the device of pernicious gases such as dust in flue gas, particle, belong to the cleaning equipment of boiler, kiln gas and the industrial waste gas of field of environment protection.
Background technology
The dry dust removal technology, cloth bag filtration method commonly used carries out dedusting, and its efficiency of dust collection height stable and reliable for performancely is widely used in dedusting.Filtrate is the core of sack cleaner, adopts strainability good usually, and chemical stability is good, the inorfil filtrate that price is low.The operation principle of sack cleaner is that dusty gas enters filter bag from the bottom, and when passing through the hole of filtrate, dust is caught to combine on the filtrate, and purified gas is discharged from exhaust outlet, thereby reaches the dedusting purpose.But along with practical application, adopt the weakness of fiber filtering also to come out, there are the shortcoming of stopping up, easily wearing out in its heatproof, wearability, corrosion-resistant, and can not wash with water in the process of deashing, have limitation, can not satisfy the requirement of dedusting.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes existing dry collector, a kind of long service life, mechanical strength height, low price, efficiency of dust collection height, easy cleaning, heatproof, corrosion resistant dry type micro porous filtration deduster are provided, this device not only can adopt the traditional machinery rotation blowback or the method for pulse backblowing in the process of deashing, also can adopt the method for washing.
Solving the problems of the technologies described above the technical scheme that is adopted is: a kind of dry type micro porous filtration deduster, comprise top cover, upper box, middle casing, ash bucket, support, on, be provided with the uniform card that has circular hole on it between the middle casing, ash bucket has and unloads the dirt valve, ash bucket is by stent support, middle casing places on the ash bucket, the top of described ash bucket is provided with air inlet, upper box is provided with exhaust outlet, it is characterized in that described in the casing circular hole position on the corresponding card be provided with the upper shed hole ceramic filter tube that declines, the upper shed of filter mantle is communicated with the inner chamber of upper box inner chamber, and filter mantle seals the circular hole on the card.
Advantage of the present invention is, to dusty gas purification efficiency height, easy to use.Adopt porous ceramic filter material to determine device in the process of deashing, not only can adopt the traditional machinery rotation blowback or the method for pulse backblowing, also can adopt the method for washing.Thereby make this device long service life, mechanical strength height, low price, have the characteristics of efficiency of dust collection height, easy cleaning, heatproof, corrosion-resistant, easy to use, stable performance.

The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a front view of the present invention.
Fig. 2 is a vertical view of the present invention.
Fig. 3 is the structural representation of filter mantle.
Fig. 4 installs the structural representation of relation for expression filter mantle and card.
Each label is represented among the figure:

The specific embodiment:
Shown in Fig. 1~4, dry type micro porous filtration deduster of the present invention, comprise top cover 1, upper box 2, middle casing 3, ash bucket 4, support 5, on, middle casing 2, be provided with the card 7 that offers uniform circular hole on it between 3, ash bucket 4 has and unloads dirt valve 6, ash bucket 4 is supported by support 5, middle casing 3 places on the ash bucket 4, the top of ash bucket 4 is provided with air inlet 41, upper box 2 is provided with exhaust outlet 21, in in the casing 3 on the corresponding cards 7 the circular hole position be provided with the upper shed hole ceramic filter tube 8 that declines, the upper shed 81 of filter mantle 8 is communicated with the inner chamber of upper box 2, filter mantle 8 seals the circular hole on the card 7.In the embodiment that accompanying drawing 3,4 provides, upper shed 81 places of filter mantle 8 are provided with flange 82, and by this flange 82, under the gravity effect by filter mantle 8 self, filter mantle 8 places on the card 7.Be provided with asbestos cord sealing gasket 9 between filter mantle 8 and the card 7.Filter mantle 8 can strengthen filter mantle or be silica enhancing filter mantle or not siliceous extraordinary filter mantle for aluminium oxide.Its cross section can be circle or rectangle or ellipse, and its filtrate micro-pore diameter is 10~400um.
The course of work of the present invention is as follows: casing 3 during dusty gas is entered by air inlet 41, dust is caught to combine in filter mantle 8 in appearance when the filtrate micropore by filter mantle 8, fall into ash bucket 4 at effect of inertia, purified gas is discharged by the exhaust outlet 21 of upper box 2 through the filtrate micropore and the upper shed 81 of filter mantle.Because filtrate is a micropore ceramic tube among the present invention, both can adopt the method for machinery rotation blowback or pulse backblowing when deashing, also can adopt method for washing.
