Description
The Pneumatic emulsifying filter belongs to liquid and separates the particle of disperse and the chemical purifying device of smog, flue gas or exhaust as release agent from gas, air or steam.
Exhaust gas discharged such as existing coal-burning boiler, metallurgical furnace, ceramic kiln, cement kiln contain pernicious gases such as a large amount of dust and SO2, NOx, CO2, and they are the primary pollution source of atmospheric environment, also are the main sources that produces acid rain.China and countries in the world all take much count of the improvement of these pollution sources.The device of Chalk-dust filtering and purifying harmful gas mainly contains gallet water curtain dust collector and spraying type dust-removing desulfurating apparatus etc. simultaneously.Though they have certain dust-removal and desulfurizing ability, but its weak point is: no matter waste gas is by moisture film, spraying area or by water-bath, the stroke of waste gas contact water (liquid) is very short, reach certain dedusting, the purpose of purifying harmful gas, must strengthen the attaching space of waste gas and liquid or the combination of employing multiple technologies, make structure of filter complexity or system huge like this, water consumption also increases.As China patent No. ZL92219420.3(CN2127637Y) " granite water dust scrubber ", it is become by the granite shaped material combinatorial surface, comprise turnover tracheae, annular water tank and dash cover, water inlet pipe, shower, scaffold etc., dust removal efficiency can reach more than 98%, and the ability of removing and harmful gas is arranged.Its weak point is that this device volume is bigger, and water consumption is also big.China's patent 91229244.X(CN2114502U and for example) " ma stone rotary deduster ", it is that moisture film, steam spray, water sprays, the dust arrester of water-bath combination, this device dust removal efficiency reaches 99.9%, but it is bigger that its weak point is a volume, water consumption is also big, also need the steam supply, promoting conforms is restricted.China's patent 89106517.2(CN1049616A for another example) " method and apparatus of industry smoke comprehensive purifying and dedusting ", it is the device of spray, water-bath combination, dust-removal and desulfurizing denitrogenation etc. is designed to one, but its volume is still bigger, also need outer power drive rotary fan to separate air water (dirt), and dedusting, desulfurization degree are not very good, and operating cost is higher relatively.
The purpose of this utility model is a kind of filter of Pneumatic emulsifying efficiently that has the while dust-removal and desulfurizing and purify other pernicious gas of design.
The purpose of this utility model is achieved in that the Pneumatic emulsifying filter is made up of hood, liquid distribution pipe, upper platen, Pneumatic emulsifying filter element, lower platen, air inlet diffuser and air inlet discharge opeing elbow etc.It will be loaded with the waste gas of dust and pernicious gas (SO2, NOx etc.) by the specific swirl-flow devices of a cover, produce the high speed swirling eddy, to pulverize by the dirty unstable liquid in filter top, form gas-liquid two-phase turbulent flow (real process is a gas, liquid, solid body particle three-phase stream), with water film dedusting, the several times of spraying and dedusting gas-liquid mixed formation, tens of times mixing stroke, gas-liquid is fully mixed, reach the emulsification degree, thereby improved the ability of liquid trap exhaust gas and dust and pernicious gas greatly.
The utility model has the advantages that:
1. dust-removal and desulfurizing rate height, dedusting are suitable for the wholegrain footpath, and dust removal efficiency reaches more than 99%, and desulfurization degree reaches 75-95%; 2. can be applicable to dried, humid gas and high temperature, the easy various media of dewfall; 3. dedusting, desulfurization constitute one, and filter volume is little, long service life (element uses more than 5 years); 4. water consumption is few, captures dust, and the water of pernicious gas (or other liquid 70-80%) can be recycled, and whole system is saved water and energy; 5. working service is convenient, and is cheap.

Fig. 1 Pneumatic emulsifying filter structure schematic representation.
Fig. 2 Pneumatic emulsifying filter A-A generalized section.
Fig. 3 Pneumatic emulsifying filter element structural representation.
Fig. 4 hydrocyclone structure schematic diagram.
Fig. 5 liquid distribution pipe structural representation.
Below in conjunction with drawings and Examples the utility model is further described:
Referring to Fig. 1 and Fig. 2, this Pneumatic emulsifying filter is made up of hood 1, liquid distribution pipe 2, upper platen 3, Pneumatic emulsifying filter element 4, lower platen 5, air inlet diffuser 6 and air inlet discharge opeing elbow 7 etc.The two ends of Pneumatic emulsifying filter element 4 are contained in respectively on the installing hole of upper platen 3 and lower platen 5, and become 120 ° of distributions with three screw rods, upper platen 3 and lower platen 5 are fastened, hood 1 usefulness flange is connected with upper platen 3, be contained in the top of upper platen 3, it is the gathering and the discharge-channel of the gas after Pneumatic emulsifying filter element 4 filters, the small end of air inlet diffuser 6 is connected with air inlet discharge opeing elbow 7 with flange, big end is connected with lower platen 5 with flange, and air inlet diffuser 6 and air inlet discharge opeing elbow 7 are inlet channels of processed waste gas.It simultaneously is again the discharge-channel that purifies emulsion.The Pneumatic emulsifying filter is the size according to the filtering gas volume flow, is made up of several or tens of Pneumatic emulsifying filter elements 4.For the convenience of installing, generally constitute one group (as shown in Figure 2), and adopt modular system with seven, with adapt to handle the flow that varies in size (as from 1 ton to hundreds of tons steam boiler exhaust gas discharged amount) needs.Liquid distribution pipe 2 is suitable with the structure of Pneumatic emulsifying filter element 4, so that liquid is imported.Liquid distribution pipe 2 is contained in the hood 1.
Referring to Fig. 3, Fig. 4 and Fig. 5, Pneumatic emulsifying filter element 4 is made up of air induction conduit 8, cyclone 9, emulsion band pipe 10, cloth liquid platen 11 and air guide catheter 12 etc., and it is the critical component of Pneumatic emulsifying filter.Air induction conduit 8 is contained in the below of cyclone 9, and it is one
100 to
200 straight-through pipe is the passage that waste gas enters Pneumatic emulsifying filter element 4.Cyclone 9 joins with an end of emulsion band pipe 10, the other end of emulsion band pipe 10 and cloth liquid platen 11 join, cloth liquid platen 11 joins with air guide catheter 12, and cyclone 9 is by 3-50 blade 13 (blade 13 is 20～70 ° with the angle α of cyclone shell 14 walls) and cyclone shell 14(internal diameter at a certain angle
