Specific embodiment
Embodiments of the invention are further illustrated below in conjunction with the accompanying drawings:
As shown in figure 1, top fan reducing discharge of waste gases clean water recovery device, including agent structure and water circulation system 6, body junction Structure includes pedestal 1, tank body 3, the first waste gas demister 31, the second waste gas demister 32, the and of the 3rd waste gas demister 33 Cooling system 34.The pedestal is provided with tank body, and tank interior is fixed with the first waste gas demister, second successively from the bottom to top Waste gas demister and the 3rd waste gas demister, the first waste gas demister top and the second waste gas demister top fill There is cooling system, tank wall is provided with air inlet 2, and air inlet is located at the horizontal down of the first waste gas demister, tank body side Wall bottom is provided with leakage fluid dram 5, and leakage fluid dram is located at the horizontal down of air inlet, and leakage fluid dram is 90~180 ° with the angle of air inlet, Leakage fluid dram is connected by water circulation system with cooling system, and tank body top is provided with exhaust outlet 4.The water circulation system includes liquid level Control valve 65, drum filter 63, clear water reserviors 64, water pump 62 and refrigeration unit 61, wherein leakage fluid dram, drum filter and clear water Pond passes sequentially through stainless steel pipes connection, and drum filter is also connected by refrigeration unit with cooling system.Drum filter with Fluid level control valve is provided between leakage fluid dram, fluid level control valve is used to adjust liquid capacity in tank body;Drum filter and refrigeration machine Water pump is provided between group, water pump is used to water be input into refrigeration unit.
As shown in Fig. 2 the first waste gas demister includes some first waveform plates 35, all first waveform plates are mutually put down Row and equidistant arrangement, the knuckle of first waveform plate is 50~70 °, and first waveform plate spacing is 38~44mm;Second waste gas demisting Device includes some second corrugated sheets 36, and all second corrugated sheets are mutually parallel and equidistant arrangement, the knuckle of the second corrugated sheet It it is 50~70 °, the second corrugated sheet spacing is 18~22mm.When high temperature (60~70 °) waste gas 37 containing mist is useless by first When gas demister or the second waste gas demister, due to the inertia of gas, mist in waste gas and corrugated sheet collide so as to It is attached to waveform plate surface.And then drop is formed at the turning of corrugated sheet, because drop is to centrifugal force and drop and waveform The tension force of the rubbing action, suction-operated and liquid surface of plate makes droplet size become big, and weight becomes big.When liquid weight is more than useless The climbing power of gas with surface tension of liquid when making a concerted effort, just from waveform plate surface separate by drop.The corrugated sheet is many foldings To structure, each knuckle of corrugated sheet plays the role of the larger mist of trapping, smaller the trapped mist body of corrugated sheet spacing Product is about small.
As shown in Figure 3, Figure 4, the 3rd waste gas demister includes at least two-layer steel wire 331, between adjacent steel silk screen Spacing is 90~110mm, and the mesh 332 of the steel wire is regular hexagon, and the section of steel wire is S-shaped, the steel wire of steel wire Section is ellipse.Waste gas is collided by silk screen, the droplet being mixed in gas with the surface of silk screen, and droplet is touched in silk screen table Behind face, it is captured down and flows downwardly into the joint that silk intersects along filament, be gathered into drop, drop constantly becomes big, Zhi Daoju Weight exceedes surface tension of liquid with gas rising buoyancy when making a concerted effort to long-pending drop in itself, and drop just overloads and settles, and reaches Remove the purpose of droplet.
As shown in figure 5, cooling system includes water pipe 341 and nozzle 342, the water pipe is fixed on tank body inner side, water pipe point Not Wei Yu the first waste gas demister and the second waste gas demister top 200~300mm places, water pipe and refrigeration unit pass through not Rust steel conduit connection, is equipped with nozzle on water pipe, nozzle is 20~30 ° with the installation angle of vertical direction.
When using, air inlet of the invention is docked with the outlet of top fan, when (60~70 °) of the high temperature containing mist gives up Gas from exhaust outlet after the first waste gas demister, the second waste gas demister and the 3rd waste gas demister by discharging.Process In, the mist in waste gas is captured and drops onto tank base, and flowing into rotary drum through leakage fluid dram by the regulation of fluid level control valve filters Device, most of drainage (about 98%) is emitted into clear water reserviors and stores after being filtered through drum filter, and fraction drainage (about 2%) is by water Pump is cooled down (be about reduced to 5 °) by refrigeration unit to be done spraying cooling agent and uses in the water pipe for importing cooling system afterwards.This hair It is bright when not only solving top fan and being worked under the air discharging and radiating system environments such as drying portion gas hood of paper machine room, directly in air The problem of middle discharge exhaust emission environment, but also make the mist in waste gas that the consumption of the energy with cycling and reutilization, can be reduced.
Specific embodiment of the invention is the foregoing is only, but technical characteristic of the invention is not limited thereto, Ren Heben The technical staff in field in the field of the invention, all cover among the scope of the claims of the invention by the change or modification made.
