For a better understanding of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings:
example 1: referring to fig. 1-2, the utility model provides the following technical scheme: the air-water separation device comprises a washing tower 1, a gas-liquid separator 4 and a fan 5, and is characterized in that a packing layer 13 is arranged in the middle of the inside of the washing tower 1, the packing layer 13 divides the inside of the washing tower 1 into an upper cavity and a lower cavity, a spraying device 32 is arranged in the upper cavity of the washing tower 1, the lower cavity of the washing tower 1 forms a reservoir 14, a first air inlet 12 communicated with the reservoir 14 is arranged at the lower part of the washing tower 1, and a first air outlet 15 communicated with the upper cavity of the washing tower 1 is arranged at the upper part of the washing tower 1; the middle part of the gas-liquid separator 4 is provided with a wire mesh demister 42, the wire mesh demister 42 divides the interior of the gas-liquid separator 4 into an upper cavity and a lower cavity, the lower cavity of the gas-liquid separator 4 is provided with a second air inlet 41 communicated with the first air outlet 15 of the upper cavity of the washing tower 1, and the upper cavity of the gas-liquid separator 4 is provided with a second air outlet 43 connected with the fan 5.
The utility model discloses use scrubbing tower 1 and vapour and liquid separator 4 to realize the clean filtration of coal dust, provide power by fan 5, gaseous entering scrubbing tower 1 back that has the coal dust, the particulate matter that contains in the gas is after packing layer 13 first filtration and spray set 32 second filtration, spray set spun water is after simple precipitation in cistern 14, the entering circulation, the dirt particle concentration that contains in the gas after filtering has reduced below the concentration that requires to discharge, contain a large amount of water smoke in the gas this moment, direct emission can lead to the fact the influence to building on every side, later remove the foam through the gas that gas-liquid separator 4 will mix there is water smoke, discharge through extension 5 after removing the foam.
Filtered gas in the washing tower 1 enters the gas-liquid separator 4, passes through the wire mesh demister 42 from bottom to top under the action of the fan, mist is attached to the surface of the wire mesh due to the fact that the mist collides with the wire mesh filaments under the action of inertia, the mist is diffused and settled under the gravity of the mist on the surface of the wire mesh, the mist forms large liquid drops and finally drops down, after the gas passes through the wire mesh demister, the content of the mist contained in the gas is effectively reduced, then the gas enters the fan through the second air outlet 43, and the gas is discharged outside through the fan 5. Preferably, the wire mesh demister 42 is selected from a wavy wire mesh demister, and the wavy wire mesh demister is used here because the effect is remarkable, and the wire mesh demister is easy to detach, convenient to clean and maintain, and the structure of the wire mesh demister can save installation space.
Further, in the above device, the packing layer 13 is disposed in the washing tower 1 near the upper half part of the first air outlet 15, and the packing layer 13 is made of a ceramic material and has a double-layer structure, and each layer of the ceramic packing layer is provided with a plurality of air holes, and the air is discharged to the subsequent gas-liquid separator 4 through the air holes under the negative pressure. The packing layer 13 is disposed on the side close to the upper side, and on the one hand, the packing layer increases the space of the lower water reservoir 14, and on the other hand, the packing layer reduces the distance of the gas flowing after passing through the packing layer 13, thereby increasing the working efficiency. The packing layer is formed by porous ceramic through high-temperature sintering, and the hard material is selected as the packing layer because the packing layer has the advantages of smooth surface, wear resistance, corrosion resistance, basically no contraction and extension phenomena, difficult blockage by particles, easy cleaning and the like, and the double layers are used for improving the filtering performance.
Furthermore, in the device, a water storage tank 14 of the lower cavity of the washing tower 1 is externally connected with a circulating water storage tank 2, the circulating water storage tank 2 is driven by a centrifugal pump 3, and the centrifugal pump 3 is simultaneously connected with a spraying device 32. The circulating water storage tank 2 connected with the water storage tank 14 is arranged on one side of the washing tower 1, the circulating water is further precipitated while the quantity of the circulating water is ensured, the circulating water is driven to circulate by using the centrifugal pump 3, then the water is driven to the spraying device 32, and flow valves are respectively arranged at the water inlet end and the water outlet end of the centrifugal pump 3 and used for controlling the flow of the circulating water.
Furthermore, in the device, the spraying device 32 is positioned right above the packing layer 13 and is fixed at the top of the water washing tower 1. Set up spray set 32 directly over the packing layer, the mode of spraying is all around covered spraying, when spraying, can cover the gas through packing layer 13 completely, collides, intercepts between dust granule in the gas and the liquid drop, and the coagulation is in the same place at last, descends along with the liquid drop, accomplishes the filtration, and simultaneously, the liquid drop that falls also can wash packing layer 13, and reducible packing layer 13's initiative cleaning frequency increases its life.
