The specific embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.
The first embodiment
Refer to Fig. 1, a kind of dedusting demister 100 that it provides for first embodiment of the invention, it comprises an absorption tower 10, at least one cold plate 20 and a collecting box 30.At least one cold plate 20 and collecting box 30 are housed in absorption tower 10, and collecting box 30 is in order to collect the liquid flowing out at least one cold plate 20.
Concrete, absorption tower 10 comprises a cylindrical tower body 11, cylindrical tower body 11 is formed with a receiving space, in order to accommodate at least one cold plate 20 and collecting box 30.In addition, receiving space is also formed with a low-pressure area.In the present embodiment, can, at the beginning of each use absorption tower 10, with air exhauster, the air of tower body 11 inside be taken away, thereby form low-pressure area.Absorption tower 10 also comprises at least one air intake vent 12 and at least one air outlet 13, for haze gas, flows into and discharges.In the present embodiment, absorption tower 10 comprises two relative air outlets 13 and an air intake vent 12, and air intake vent 12 is arranged on tower body 11 tops, and air outlet 13 is arranged on tower body 11 bottoms.Be appreciated that the volume on absorption tower 10 is the bigger the better in order to absorb more haze gas.In addition, air intake vent 12 places can arrange one or at least two air-blast device (not shown), so that gas flow intensity is larger, thereby improve absorption efficiency.
Incorporated by reference to Fig. 2 and Fig. 3, more specifically, the cooling tube 22 that each cold plate 20 comprises waveform plate body 21 and is arranged on plate body 21 bottoms, cooling tube 22 can reduce the temperature of plate body 21, when haze gas enters absorption tower 10 when interior from air intake vent 12, contact with plate body 21, now, cold plate 20 can, by haze gas liquefaction, be adsorbed on liquid the particulate in haze gas.Because waveform plate body 21 has larger contact area, can make haze gas more fully liquefy, make assimilation effect better.In addition, at least two the intensive apertures of can annotating on cold plate 20, thus make cold plate 20 there is the effect of filtering gas microparticle.The aperture that is appreciated that aperture is less, and the effect of filtering particle in haze gas is better.In order to increase distribution area, cooling tube 22 is formed by least two U-shaped pipes that connect successively.In the present embodiment, in cooling tube 22, be liquefaction nitrogen.Be appreciated that cooling tube 22 also can be with other cooling agent.
Collecting box 30 is arranged in absorption tower 10, and is oppositely arranged with at least one cold plate 20, in order to collect the liquid at least one cold plate 20.In the present embodiment, collecting box 30 is arranged between two air outlets 13, and with air intake vent 12 over against setting.In addition, collecting box 30 is also communicated with a pipeline 31, in order to the condensed fluid in collecting box 30 is discharged in time, thereby keeps the operation cycle on whole absorption tower 10.
While using dedusting demister 100, first by cooling tube 22, reduce the temperature of cold plate 20, then make tower body 11 form low-pressure area, haze gas outside tower body 11 is because tower body 11 internal gas pressures are low, can enter 10 inside, absorption tower by air intake vent 12, the moisture entering in the haze gas in tower body 11 is encountered the rear liquefaction of cold plate 20, and condenses the particle in haze gas, thereby makes air obtain preliminary purification.Air after purification is discharged by the air outlet 13 on absorption tower 10, and the particles such as dust that adhere to can drop on cold plate 20 together along with drop or moisture on drop after liquefaction or moisture, and when water droplet gathers to a certain degree, can from cold plate 20 be slipped on ground or collecting box 30 on.
In addition, change the liquid nitrogen cooling tube 22 on cold plate 20 into corona machine line, dedusting demister 100 just can utilize the principle of electrostatic precipitation to process haze gas.Specifically, corona wire is negative pole, and effect is electric discharge.Cold plate 20 ground connection, have zero potential, are equivalent to dust collection plate.Anion moves to zero potential end, and separated by electricity while making haze gas through high-voltage electrostatic field, grit is combined with anion and is with after upper negative electricity, and trend dust collection plate discharges and deposits.Therefore, dedusting demister 100 of the present invention can switch to electrostatic precipitator easily, simple to operate, and has saved user's cost.
