Abstract

The utility model discloses a waterfilm filter for smoke in tubing arranged on the fire smoke tubing. The utility model is a practical and convenient device for protecting environment, comprising a box body, a filtering net, a sprinkler head, a smoke inlet, a smoke outlet, a cleaning door, a drain outlet, etc. The filtering net of the box cavity divides the box cavity into two parts of a catch adsorption chamber and a condensation liquefying chamber; the filtering net which comprises a flat conic filtering net and a ribbon filtering net is matched with the rotary sprinkler head to open and close the cleaning door at any time. The utility model has the advantages of high smoke removal rate, convenient cleaning, small size, and low cost.

Description

Waterfilm filter for smoke in tubing

The utility model relates to environment protection equipment, the purified treatment of the fiery cigarette tail gas that is produced when being mainly used in the burning of diesel oil evaporation stove and relatively large coal stove.

Current, growing along with the catering trade, the continual renovation of cooking apparatus is regenerated, day by day increase to the discharge capacity that makes cooking stove fire cigarette, but because fiery smoke waste gas majority is the non-processor discharging, cause environmental pollution serious day by day, the masses' complaint also increases day by day, and the processing of using at present fire smoke waste gas environmental protection equipment does not have the product of typing, such used environmental protection equipment of general producer, be respectively to accept the improvement unit to design voluntarily mostly, and be mostly single-piece production, do not advise one very much, thereby cost is higher, and regulation effect is also undesirable.At present useful tower, box processing fire cigarette equipment, but this kind equipment is owing to will focus on fiery cigarette, equipment volume is bigger, cost is higher, floor space is also bigger, thus use than the difficult restaurant, restaurant that is fit in the urban compact district, and often will handle with steel mesh and asbestos putty parcel the heat radiation of handling the preceding pipeline appearance, treatment cost is increased, and the regular cleaning maintenance of this kind equipment also bothers.

At above-mentioned situation, the utility model adopts moisture film condensation method and filter screen to hold back the absorption method principle of combining, designs a kind of light and handy, convenient, practical, pipeline fire cigarette moisture film cleaner of not accounting for the place, and fiery smoke waste gas is handled.

Accompanying drawing 1 is the structural representation (cut-away view) of the vertical fiery cigarette moisture film cleaner of pipeline.

Waterfilm filter for smoke in tubing mainly by casing, filter screen, Water membrane nozzle, discharge outlet, advance mouth and outlet flue etc. and form. Filter screen is installed in casing 1, filter screen is divided into upper and lower two parts with the case chamber, what be positioned at filter screen (comprising filter screen) top is condensation liquefaction chamber 10, is positioned at Below the filter screen is to hold back adsorption chamber 8, in the position over against filter screen, but has the cleaning door 2 of a freely openable at casing middle part. Filter screen is made up of two parts, and top is divided into flat pyramidal structure (conical screen 3), and the bottom is divided into flat rubber belting shape structure (lower filter screen 4), and two part filter screens link to each other with casing by support 9.

Hold back adsorption chamber 8 by filter screen, nowel chamber, water fender 5 in the filter case chamber, advance mouth 6 and discharge outlet 7 and form, filter screen is fixed in the casing by support, advances mouth 6 and opens side in the nowel chamber, discharge outlet 7 is opened the bottom at lower chamber, and water fender is welded on the top casing of mouth into.

Condensation liquefaction chamber 10 is by filter screen, top box chamber, door 2, shower nozzle 11(and water inlet pipe) outlet flue 12 etc. forms, and shower nozzle is positioned at the top of filter screen and is connected with water inlet pipe, and outlet flue is positioned at the top in case chamber.

Filter screen adopts the steel silk screen, and the aperture is ∮ 2～∮ 6, and punching rate is between 30～70%, and also available other metal or nonmetal net replace; Spraying nozzle adopts centrifugal mini sprinkler, and operating pressure is 1～2.5kg/cm ², flow is 100～300kg/ hour, and water inlet pipe and water outlet pipe adopts common galvanizing pipe, and the jettison gear that connects discharge outlet adopts the cock of band articulation.

In conjunction with the accompanying drawings 1, the course of work of fiery cigarette moisture film cleaner is described.

Shown in the accompanying drawing 1, the fiery smoke waste gas that comes from fiery smoke pipe road is by after advancing mouth 6 and entering cleaner, wherein unburnt as granular, the particle of thread and dust-like, holding back in the adsorption chamber 8 of cleaner by

filter screen

3,4 hold back and catch, under the effect of moisture film, be adsorbed on the particle in the filter screen, be rinsed to be discharged in three grades of filter tanks and go by discharge outlet 7, do not held back the particle of catching by filter screen, in condensation liquefaction chamber 10 by under the atomized water film condensation effect under shower nozzle 11 spray, change liquid into by waste gas, also be washed in three grades of filter tanks by discharge outlet and go to handle again, waste gas is after treatment then drained by outlet flue 12.Because entering the mouth top has an oblique water fender 5, so the waste water that flows down from the condensation liquefaction chamber can not enter into mouth 6, thereby has ensured that duct coupling is not corroded by waste water.In the effect of atomizing moisture film, the part heat of waste gas is also cooled off, takes away by moisture film.The moisture film cooling reaches 50～60%, and the gas temperature of Pai Chuing is discharged by chimney by discharge tube between 80～200 ℃ after treatment, has reduced the waste gas heat radiation pollution.

Accompanying drawing 2 is the vertical view of cleaner, and 1 is casing among the figure, and 6 for advancing mouth, and 11 is rotating sprinkler, and 12 is outlet flue.

This filter design novelty has the following advantages:

1. volume is little, does not account for the place, can design, produce according to existing fiery smoke pipe road.

2. install easily, it can be installed in fiery cigarette exit, and is the same with general pipeline installation, tightens up with bolt to get final product.

3. smoke abatement is effective, contained carbide, sulfide, dust etc. in the fiery cigarette, and net filtration and moisture film flushing after filtration, total filter effect reaches more than 90%, lowers the temperature about 100 ℃.

Cleaning maintenance easily, since be equipped with clean door, the installation site is low, if open door closure, capable of washing will clean the time.

5. cost is low, and materials are economized, and construct uncomplicated.

6. highly versatile, individual shop or big used by hotels and restaurants by, worker dining room all can be used.
