Description

A kind of waste incineration and generating electricity exhaust-gas treatment bag-type dust case

Technical field

The invention belongs to rubbish technical field of waste gas treatment, and in particular to arrive a kind of bag filter, more particularly one Kind waste incineration and generating electricity exhaust-gas treatment bag-type dust case.

Background technique

The bag-type dust case is exactly the equipment that dust is separated from flue gas, and bag filter is also referred to as filtering type Deduster is a kind of dry type high efficiency deduster, it is to trap ash-laden gas using the bag type filter elements of fibrous braid production The dust-extraction unit of solid particulate matter in body, action principle are that grit is touched because inertia force is acted on fiber when around fiber cloth It hits and is intercepted, cloth envelop collector can be divided into inward flow filtration-type and two kinds of outside filtering type, but existing bag dedusting box function by filter structure It is relatively simple, it is correspondingly improved although having, but still it is impossible to meet demands when people's use；

There are certain drawbacks in existing bag-type dust case, conventional cloth bag dust cleaning case only has single during use Filter structure so that exhaust gas, after the filtering of bag-type dust case discharge, gas interior passes still doped with certain dust Bag-type dust case unite during long-time use, packing phenomenon occurs in bottom dust, so that the dust of bag-type dust case Ash bucket is easy to appear choking phenomenon, and conventional bag dust cleaning case only has single inward flow filtration-type or outside filtering type in the design of dust-removal cloth-bag A kind of filter structure reduces the Bag filter structure of bag-type dust case itself, and function is relatively simple, brings centainly to user Adverse effect.

Summary of the invention

In order to overcome above-mentioned technical problem, the purpose of the present invention is to provide a kind of waste incineration and generating electricity exhaust-gas treatment use Bag-type dust case enters cabinet shell using progress in dusty gas by the way that limit fastener, dual dust settling pocket and demarcation plate is arranged When dust removal operation, dusty gas can enter the bottom of dual dust settling pocket, dusty gas by the air inlet of dual dust settling pocket bottom After the filtering of the outer surface of dual dust settling pocket, dust is blocked on the outer surface of filter bag, so that external filter operation is completed, The top that dual dust settling pocket can be entered by one-way valve by external filtered dusty gas, using demarcation plate to dual dedusting Bag up and down two be isolated, gas enter dual dust settling pocket top after so that dual dust settling pocket top expands rapidly, contain After the filtering of the inner surface of filter bag, dust is blocked on the inner surface of filter bag dust and gas body, so that self-filtering operation is completed, Dual dust settling pocket plays buffer action to the gas filtered twice, and dual dust settling pocket is using the interior double filtration filtered with outer filtering Structure design so that dusty gas enter dual dust settling pocket it is primary after, filter operation twice can be completed, thus effectively promoted should The bag-type dust effect of bag-type dust case when gas is after Bag filter, is passed through by setting spray dust's case and settling tank Connecting tube enters spray dust's case, and user conveys water body, water into spray dust's case using the water inlet tube head of spray dust's case Body sprays, the water mist after ejection can drench water filter plate, when gas passed through drainage after the processing of water mist spraying head in mist state After plate, crossing water filter plate can be with dust remaining in adsorbed gas using the water body on its surface, and the water mist that water mist spraying head sprays can To carry out secondary dust removing processing to gas, the water body for carrying dust can enter settling tank using water pipe by catch basin, pass through After settling tank precipitating, water body is extracted out from discharge outlet again, using the design of spray dust's case and settling tank, so that the bag-type dust Case has water mist dust fall structure, so that its dust removing effects is effectively promoted, by setting dredging pipe and flexible tube head, in dust ash bucket When interior dust siltation phenomenon phenomenon occurs because of long-time use, user can pass through the operation rotation for rotating dredging pipe Button moves it up so that operation knob drives dredging pipe to utilize the screw thread on its surface, during dredging pipe moves up, Flexible tube head is enabled to do upward moving in rotation, during the rotation of flexible tube head, the metal blade that top is installed is done in the same direction Rotation enables the cleaning operation of equipment more convenient so that the dust to siltation in dust hopper bottom plays elicitation effect.
