Description
Technical field
The present invention relates to gas cleaning plant, relate in particular to a kind of dust arrester, specifically a kind of water mist dust-removing device.
Background technology
At present, known dust removal machine is of a great variety, and centrifugal, water spray type, atomizing, electrostatic or the like are arranged.Chinese patent CN200620017143 discloses a kind of water-bath, water mist dust-removing machine.With reference to Fig. 1, this dust removal machine comprises body 3 ', water pipe 5 ' and shower nozzle 8 ', is provided with " Ω " shape kuppe 4 ' in the body 3 ', and body 3 ' bottom retaining forms the water bath dust-removing space; Kuppe 4 ' covers air inlet 6 ', water pipe 5 ' and shower nozzle 8 ' and forms the first water mist dust-removing space, and kuppe 4 ' under shed immerses in the water of water bath dust-removing space, body 3 ' bottom; Kuppe 4 ' outer wall and body 3 ' inwall form UNICOM's air outlet behind the second water mist dust-removing space.Its operation principle is following: after taking out dirt blower fan, water pump and starting simultaneously, the air-flow of dust-laden gets at a high speed in the body 3 ', and water inlet pipe mixes with the air-flow of dust-laden through hydraulic type rotary nozzle ejection water, in the kuppe inner bag generation water mist dust-removing effect first time; Water dust is mixed in the water of underpart water bath dust-removing space, and the water surface of ash settling basin produces the water bath dust-removing effect bottom squeezing into from the water-bath shower nozzle; Water dust stream flows into the second water mist dust-removing space on the water dust flow direction under the effect of arc through the water-bath shower nozzle and eddy current supercharging deflector 10 ' the blast effect under, carry out the water mist dust-removing second time; Last water smoke under the effect of water fender, makes the mist vapour condensation in the water smoke through demist water retaining tank 2 ', and clean air is discharged from air outlet.
Yet, above-mentioned water-bath, water mist dust-removing machine, air-flow is carrying out first time water mist dust-removing after the water bath dust-removing space gets into the second water mist dust-removing space again; Because the resistance of air-flow in water is bigger; The energy consumption of air-flow is very big, thereby influences the speed of dedusting, so efficiency of dust collection is not high.Simultaneously, because the stroke of air-flow is shorter, also reduced dust removing effects to a certain extent.In addition, the second water smoke space does not have shower nozzle and produces the spray effect, therefore is difficult to reach further water mist dust-removing effect.
Summary of the invention
What the present invention will solve is the low and dissatisfactory problem of dust removing effects of efficiency of dust collection that prior art exists, and aims to provide a kind of efficiency of dust collection height, the even more ideal water mist dust-removing device of dust removing effects.
For addressing the above problem; The present invention adopts following technical scheme: a kind of water mist dust-removing device, comprise body and water pump, and described body one end is provided with air admission hole; Other end top is provided with steam vent; It is characterized in that said body upper is provided with one group of vertical or oblique deflector, underpart is a cistern, is provided with the water smoke cold plate under the steam vent; Described one group of deflector comprises upper strata deflector and the lower floor's deflector that is arranged alternately, and the both sides of each deflector are connected with the sidewall of said body; The top of upper strata deflector is connected with the top of body, forms gas channel between the water surface of bottom and cistern; Lower floor immerses in the water of cistern the deflector bottom, forms gas channel between the top of top and body; Described one group of deflector top is provided with some showers, and described water pump one end is through water inlet pipe and cistern UNICOM, and the other end is through feed pipe and described each shower UNICOM.
Water mist dust-removing device of the present invention; In cistern, be filled to the working water bit line; Start earlier water pump and makes shower begin spray, restart blower fan the dusty gas of working site is got into dust arrester through ventilation shaft, the water smoke that dusty gas is sprayed through each deflector time dirt that goes out; Water smoke gas after the dedusting is condensed into water droplet through the water smoke cold plate with water smoke again and drips back cistern, pure gas through cold plate after from steam vent entering exhaust square tube and then enter sky.
The present invention adopts the deflector structure that is provided with in groups, and dusty gas is flowed by curve mode along the direction of deflector, has prolonged the gas flow distance, has promptly prolonged spray and has gone out the time of dirt, thereby improved the effect of the dirt that goes out.And, because air-flow always flows, do not have extra resistance in gas channel, so flowed energy consumption is less, efficiency of dust collection also is improved.
As further improvement of the present invention, first deflector adjacent and the oblique setting of second deflector with described air admission hole, other deflector is vertical setting.Described first deflector is horizontal by 110 °～135 ° settings, and described second deflector is horizontal by 45 °～65 ° settings, can reduce to get into the resistance of the dust air-flow of air admission hole, makes it import to follow-up deflector smoothly.
According to the present invention, described deflector is 4-6 is advisable, and according to contained dust granules in the air-flow what, regulates in conjunction with the overall dimensions of body.
According to the present invention, described feed pipe can link to each other with an end of said each shower.This structure, feed pipe can be arranged in the side of body, and structure is simple relatively, easy mounting and realization.
The embodiment of another optimization, described feed pipe links to each other with the middle part of said each shower.Feed pipe enters into the top in the body from the side or the end of body, is connected to the middle part of each shower.Its advantage is that water under high pressure send water from the middle part of each shower to two ends, and the hydraulic pressure in each shower is even relatively, can guarantee still to keep higher hydraulic pressure after water under high pressure arrives the two ends of each shower, makes and all obtains all good spray effect in the whole gas channel.
Further improve again as of the present invention; Described body comprises steel structure frame, stainless steel wallboard and stainless steel top board; Described steel structure frame is welded by rectangular steel pipe, and described stainless steel wallboard is welded on the described rectangular steel pipe after by the corrosion resistant plate flanging.Adopt stainless steel material to make body, can play antirust, corrosion-resistant effect, the service life that can improve complete machine.Wall panel flaps can play the effect of gaining in strength, and then can reduce the consumption of material, reduces manufacturing cost.
Further improve again as of the present invention, also be provided with the exhaust square tube on the described steam vent.Described exhaust square tube is made up of steel structure frame and stainless steel wallboard, can reliably be connected with described body.
Further improve as of the present invention; The nozzle of described shower carries out suitable arranging, and the water smoke that adjacent nozzle is sprayed overlaps each other, and whole gas channel effective cross section is carried out fully reasonably covering; Its spray coverage rate is greater than 200%; The cross section spray flux is even, and the gas-liquid contact-making surface is big, can effectively fall the raising efficiency of dust collection.
