Abstract
The invention discloses a kind of mostly de- bag filter of smoke catalytic, including double-layered filtering bag, the outer layer of double-layered filtering bag is surface filter bag, and the internal layer of double-layered filtering bag is catalysis filter bag, has reducing agent jet port and sorbent injection mouth on the gas approach of double-layered filtering bag.It carries out desulphurization and denitration, dedusting and de- dioxin simultaneously in double-layered filtering bag, realizes more de- processing.
Description
Technical field
The present invention relates to bag filter, in particular to the mostly de- bag filter of a kind of smoke catalytic.
Background technique
Bag filter has a single function at present, can only dedusting, can not carry out desulphurization and denitration and de- dioxin；Simultaneously
The equipment such as existing desulphurization and denitration are more, and land occupation is more, at high cost；So be badly in need of one kind desulphurization and denitration, dedusting, de- two can dislike simultaneously
The mostly de- bag filter of the smoke catalytic of English.
Summary of the invention
The object of the present invention is to provide a kind of mostly de- cloth of smoke catalytic for capableing of desulphurization and denitration, dedusting, de- dioxin simultaneously
Bag dust collector.
Present invention provide the technical scheme that a kind of mostly de- bag filter of smoke catalytic, including double-layered filtering bag, bilayer filter
The outer layer of bag is surface filter bag, and the internal layer of double-layered filtering bag is catalysis filter bag, has reducing agent spray on the gas approach of double-layered filtering bag
Loophole and sorbent injection mouth.
Further, the reducing agent jet port sprays ammonia.
Further, the sorbent injection mouth injection active carbon and calcium hydroxide.
Compared with the existing technology, the beneficial effects of the present invention are: flue gas by gas approach enters bag filter after furnace
In, reduction and the adsorbents such as ammonia, calcium hydroxide, active carbon are sprayed into gas approach, calcium hydroxide and activated carbon adsorption are in surface
Filter bag is reacted, and sulfur dioxide and dioxin are absorbed and react；Ammonia reacts production with oxide under the action of being catalyzed filter bag
Raw nitrogen, carries out desulphurization and denitration, dedusting and de- dioxin simultaneously in double-layered filtering bag, realizes more de- processing.
Detailed description of the invention
Fig. 1 is double-layered filtering bag structure chart of the present invention；
Fig. 2 is process flow chart of the invention；
The label in accompanying drawing is: surface filter bag 1, catalysis filter bag 2.
Specific embodiment
In order to further understand the content, features and effects of the present invention, special lift following embodiment, and cooperate attached drawing detailed
Carefully it is described as follows.But they are not construed as limiting the invention.
As shown in Figure 1, the present invention provides a kind of mostly de- bag filter of smoke catalytic, including double-layered filtering bag, double-layered filtering bag
Outer layer be surface filter bag 1 (being the filter bag of conventional dust removal), the internal layer of double-layered filtering bag is that catalysis filter bag 2 (is with catalytic effect
Filter bag), there is on the gas approach of double-layered filtering bag reducing agent jet port and sorbent injection mouth.
The reducing agent jet port installs atomizing lance, and ammonia is ejected from atomizing lance by compressed air.
There are two the sorbent injection mouth tools, and one is to spray active carbon by roots blower, another is also to pass through
Roots blower sprays calcium hydroxide.
As shown in Fig. 2, flue gas is entered in bag filter by gas approach after furnace, sprayed into gas approach ammonia,
The reduction such as calcium hydroxide, active carbon and adsorbent, calcium hydroxide and activated carbon adsorption are reacted in surface filter bag 1, are absorbed and are reacted
Sulfur dioxide and dioxin；Ammonia, which reacts under the action of being catalyzed filter bag 2 with oxide, generates nitrogen, in double-layered filtering bag simultaneously
Desulphurization and denitration, dedusting and de- dioxin are carried out, realizes more de- processing；Purified flue gas is by chimney outlet, when using one section
Between after, by double-layered filtering bag ash cleaning transfer out.
Although the preferred embodiment of the present invention is described above in conjunction with attached drawing, the invention is not limited to upper
The specific embodiment stated, the above mentioned embodiment is only schematical, be not it is restrictive, this field it is common
Technical staff under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, may be used also
By make it is many in the form of, within these are all belonged to the scope of protection of the present invention.
