Abstract

The utility model discloses a smoke filter device composing a waterproof cap on the chimney top, a cylinder fixedly connected with the chimney upside by a framework, a plurality of sprinklers connected with the water inlet in the cylinder, and a water collecting channel at the bottom of the cylinder. The upper head of the water inlet is connected with a sprinkling pipe. A sprinkling hole is positioned on the sprinkling pipe, of which the inferior is provided with a bevel filter screen. A fan is hung at the center of the framework top. The water collecting channel is connected with a settling reservoir by a downpipe. A high-pressure hydraulic pump is positioned between the water inlet and the reservoir. Being economical and practical, the utility model has simple structure and rational designing, and is easy to be reconstructed on the existing equipment. The environmental pollution of the industrial waste gas is greatly reduced by adopting the two dust removal modes of atomization sprinkle and wind power force fan, and the dust removal effect is obvious. The cost is lowered by using the circulating water to carry out dust removal of the chimney.

Description

The filtrating smoke dust device

Technical field:

The utility model is a kind of environmental protection equipment, a kind of specifically smoke evacuation dedusting filter that is connected on the chimney.

Background technology:

Along with industrial expansion, people produce, in the life to airborne release a large amount of smog, except fine dusts, also have carbon monoxide, carbon dioxide, nitric oxide, sulfur dioxide or the like toxic and harmful in these smog.Except vehicle exhaust, be that the chimney of fuel also is main pollution sources with the coal.A large amount of flue dust and acid mist are having a strong impact on people's living environment and healthy, and therefore, country takes the policy of closing down for the producer of the discharging that exceeds standard.Enterprise wants survival and development, necessary contaminated solution problem, and therefore large quantities of cleaners miscellaneous arise at the historic moment; For the CN2760412 Chinese patent a kind of utility model " device for eliminating smoke and dust " is disclosed as publication number, cavity body is installed in employing on chimney stack, establish bucker on the throat of cavity body bottom, the fountain head that at least one is connected with water inlet pipe is housed in the cavity body, this device has certain filter effect, but the water droplet and the flue dust of fountain head ejection are limited time of contact, are difficult to the dust removing effects that reaches good, particularly for small dust; And other disclosed most cleaner complex structure, floor space is big, and investment is many, and operating cost is also high, is difficult to realize for medium-sized and small enterprises.

Summary of the invention:

Technical problem to be solved in the utility model is exactly to overcome the problem that exists in the above cleaner, and custom-designed a kind of rational in infrastructure, easy to use, the tangible chimney emission dedusting filter of dust removing effects.

The purpose of this utility model takes following technical scheme to realize:

A kind of filtrating smoke dust device, the water leg that comprises the waterproof cover, the cylinder on chimney top, the interior a plurality of shower nozzles that are connected with water inlet pipe of cylinder and the cylinder bottom that are located at the chimney top, chimney is connected by skeletal fixation with cylinder, the water inlet pipe upper end also is connected with sprinkler pipe, has water sprayering hole on the sprinkler pipe, and the sprinkler pipe below is provided with filter screen, the middle part of filter screen is provided with fan, fan is hung in the skeleton top end, and water leg is connected with the precipitation pond by downcomer, also has high-pressure hydraulic pump between water inlet pipe and the pond.

The outstanding skeleton top center place that is connected on of described fan.

In order to improve ventilative area and filter densities, filter screen adopts knuckle shape filter screen.

Described shower nozzle and fan all are provided with along cylinder center.

For dust is fully contacted with water smoke, shower nozzle adopts atomizer.

Described water inlet pipe is provided with filter at the end in precipitation pond.

The beneficial effect that the utility model can reach is:

1, the utility model is simple in structure, and is reasonable in design, is easy to transform on existing equipment, economical and practical.

2, the utility model adopts atomizing spray and wind-force to force the attached dual mode dedusting of fan, and dust removing effects is obvious, has alleviated the pollution of industrial waste gas to environment greatly.

3, the utility model is provided with the precipitation pond, adopts recirculated water that chimney is carried out dedusting, and use cost is low, the device economical operation.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model plan structure schematic diagram.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

Referring to Fig. 1, Fig. 2, this filtrating smoke dust device comprises the waterproof cover 5 that is located at chimney 4 tops, the cylinder 14 on chimney 4 tops, cylinder 14 is fixed on the skeleton 7 in the outside, have a plurality of atomizers 6 that are connected with water inlet pipe 11 and the water leg 3 of cylinder 14 bottoms in the cylinder 14, also be connected with sprinkler pipe 15 on the water inlet pipe 11, has water sprayering hole on the sprinkler pipe 15, atomizer 6 and fan 8 all are arranged on the center of cylinder 14, fan 8 is hung in skeleton 7 center of top, the position of the corresponding fan 8 in cylinder 14 upper ends is provided with knuckle filter screen 9, water leg 3 is connected with precipitation pond 1 by downcomer 2, also be provided with high-pressure hydraulic pump 10 between water inlet pipe 11 and the precipitation pond 1, water inlet pipe 11 is provided with filter 13 at the end in precipitation pond 1.

When chimney emission, open high-pressure hydraulic pump 10 and fan 8, the water that then precipitates in the pond 1 sprays in the upper end sprinkler pipe 15 of a plurality of atomizers 6 and knuckle filter screen 9 through water inlet pipe 11; Because the top of chimney 4 is provided with waterproof cover 5, so water droplet can not fall into the internal orifice of chimney 4, flue dust is emerged from the side of waterproof cover 5, the water smoke that several atomizers 6 are sprayed, in cylinder 14, form the multi-stage jet layer, flue dust, other toxic and harmful and molecule fully contact with little water droplet, fall into the water leg 3 of below after adsorbing along with water droplet, flow into precipitation pond 1 through downcomer 2 again.Knuckle filter screen 9 tops have sprinkler pipe 15 again, under the effect of fan, the soot dust granule that has been full of moisture is under the effect of gravity and wind-force, blow off sprinkler pipe 15 waterings formed washing away above the cascade on knuckle filter screen 9, the soot dust granule that is attached in the knuckle filter screen 9 is finally still rushed in precipitation pond 1, through the flue gas of above-mentioned dedusting and filter process, substantially totally harmless, reached the discharge standard of national requirements.Need to prove: at above-mentioned dust removal process, the acidic materials in the flue dust are dissolved in the water, in order to alleviate the corrosiveness of recirculated water middle acid substance to equipment, can add an amount of alkaline matter in recirculated water.
