As depicted in figs. 1 and 2, the utility model boiler smoke dedusting and purifying device comprises cylindrical shell 10, guide layer 20, spray pipeline 30 and supplies water assembly 40.
The lower end of cylindrical shell 10 is provided with smoke inlet 11, and upper end is provided with exhanst gas outlet 12, because cylindrical shell 10 is made up of thin corrosion resistant plate, in order to ensure the stability of cylindrical shell 10 profile, structure, preferably, is provided with multi-turn reinforcing ring 15 at the inwall of cylindrical shell 10.
Spray pipeline 30 is placed in the inside of cylindrical shell 10, it spray arm 32 comprising spray supervisor 31 and communicate with spray supervisor 31, spray supervisor 31 is located at the centre of cylindrical shell 10, spray arm 32 extends from spray supervisor 31 to the inwall of cylindrical shell 10, the tube wall of spray supervisor 31 and spray arm 32 is all provided with the first hole for water spraying, and this first hole for water spraying is used for carrying out spraying and dedusting to the flue gas in cylindrical shell 10.
In this preferred embodiment, as depicted in figs. 1 and 2, at sustained height, 4 spray arms 32 arranged in cross are set, shower water in spray supervisor 31 flows into along the direction of arrow in the figure and sprays arm 32, then is sprayed in flow-guiding channel 23 by the first hole for water spraying formation water smoke of spray supervisor 31 and spray arm 32.Certainly, the quantity and the location arrangements that spray arm 32 are not limited to the mode of showing in this embodiment.
In addition, spray supervisor 31 has the different multistage tube chamber 31a of hydraulic pressure, is not communicated with each other between different tube chamber 31a, and has spray arm 32 to be connected with each section of tube chamber 31a.In the process that flue gas rises along flow-guiding channel 23, the concentration of its pollutant also constantly can change in the process of purification, this just needs the water smoke spray volume of the spray arm 32 of adaptive adjustment each tube chamber 31a and differing heights, adopt the spray pipeline structure of multistage controllable pressure in the present embodiment, the purification requirement of various concentration flue gas can be met neatly.
Guide layer 20 is formed in the shape of a spiral and with cylindrical shell 10 inwall and is used for the flow-guiding channel 23 that circulate of flue gas, and flow-guiding channel 23 is communicated with smoke inlet 11 and exhanst gas outlet 12.Guide layer 20 comprises cyclone pipe 21, two-sided screen pack 22 and absorbent filter medium, and cyclone pipe 21 spiral welded is in the inwall of cylindrical shell 10, and two-sided screen pack 22 is located between spray supervisor 31 and cyclone pipe 21, and absorbent filter medium is filled among two-sided screen pack 22.In the present embodiment, two-sided screen pack 22 is two-sided stainless (steel) wire, and absorbent filter medium is then preferably active carbon.
Further, cyclone pipe 21 communicates with spray supervisor 31, and its tube wall is provided with the second hole for water spraying, like this, can play in cylindrical shell 10 atomizing spray effect except spray supervisor 31 and spray arm 32, also have the cyclone pipe 21 arranged around cylindrical shell 10 spiral inner wall.The effect of cyclone pipe 21 has two: the first, and auxiliary spray, especially carries out spraying and dedusting to the inwall of cylindrical shell 10; The second, support two-sided screen pack 22.
For water assembly 40 for providing shower water to spray pipeline 30, it comprises water pump 41, water inlet supervisor 42 and water inlet pipe 43, water inlet pipe 43 communicates with spray supervisor 31, and the pipeline of water inlet pipe 43 is provided with hydraulic valve 44, and hydraulic valve 44 is for controlling the hydraulic pressure of the tube chamber 31a spraying supervisor 31.
The lower end of cylindrical shell 10 has in cone shape dust collecting part 13, and the bottom of this dust collecting part 13 is provided with sewage draining exit 13a, and dust collecting part 13 is gathering-devices of shower water, and the precipitation such as the granule foreign in shower water post-concentration collection is at the sewage draining exit 13a place of lower end.The suction side 41a of water pump 41 communicates with the upper position of dust collecting part 13 and forms circulation waterway, and the Inner eycle in water route can reduce the volume of this purifier.But in various embodiments, water pump 41 can absorb water from external water storage device or cistern, to ensure the cleannes of shower water.
Be provided with overfall 14 in cylindrical shell 10 lower end, near the position of dust collecting part 13 upper end, the effect of overfall 14 is exactly the accumulation preventing shower water excessive, affects the air inlet of smoke inlet 11 and the circulation of flue gas.
Fig. 3 shows the utility model boiler smoke dedusting and purifying device inside smoke flow schematic diagram.As shown in Figure 2, flue gas enters cylindrical shell 10 along the direction of arrow in figure from smoke inlet 11 inner, and the flow-guiding channel 23 formed along guide layer 20 and cylindrical shell 10 upwards flows, until exhanst gas outlet 12.In this process, the particle of Large stone collides with the inwall of cylindrical shell 10 under the influence of centrifugal force, and because Action of Gravity Field falls, flue gas then continues to rotate and rises, and then completes the ground floor purification process of flue gas.
Fig. 4 shows the utility model boiler smoke dedusting and purifying device inner shower water circulation schematic diagram.As shown in Figure 4, shower water is along direction of arrow flowing in figure, the shower water of dust collecting part 13 inside is entered spray supervisor 31 by water inlet supervisor 42, water inlet pipe 43 by the suction side 41a of water pump 41, shower water dispersion is flowed into spray arm 32 and cyclone pipe 21 by spray supervisor 31 again, spray supervisor 31, spray arm 32 and cyclone pipe 21 all spray water smoke by hole for water spraying to cylindrical shell 10 inside, and water smoke drop in dust collecting part 13 again and namely completes a shower water circulation.In this process, the water smoke in cylindrical shell 10 and flue gas meet, and the resolvability pollutant in flue gas and the particle of small particle diameter all merge with water smoke, after be condensed into mixed solution along with water smoke, flue gas continues to rise, and then completes the second layer purification process of flue gas.
Two-sided screen pack 22 between cyclone pipe 21 and spray supervisor 31 and absorbent filter medium have three effects: the first, retain bulky grain pollutant; The second, contribute to the condensation of water smoke; 3rd, absorbent filter medium can adsorb small particles of pollution thing in flue gas and the specific difficult material removed further, completes the third layer purification process of flue gas.
More than that preferred embodiment of the present utility model is illustrated, but the utility model is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
