As shown in fig. 1, the present invention discloses a desulfurization and denitrification apparatus 10 convenient for disassembly, assembly and maintenance, comprising: a filtering and settling cylinder 100, a desulfurization and denitrification cylinder 200 and a negative pressure atomization cylinder 300.
As shown in fig. 1 and 2, the filtering and settling cylinder 100 is disposed on the ground through a fixing bracket 400, the desulfurization and denitrification cylinder 200 is detachably mounted on the filtering and settling cylinder 100, and the desulfurization and denitrification cylinder 200 is communicated with the filtering and settling cylinder 100 to form a hollow cavity; an air inlet interface 210 is arranged on the end surface of the desulfurization and denitrification cylinder 200, and the negative pressure atomization cylinder 300 penetrates through the air inlet interface 210 and is partially accommodated in the hollow cavity. An exhaust port 220 is formed in the side wall of the desulfurization and denitrification cylinder 200; the side wall of the filtering and settling cylinder 100 is provided with a water inlet 500 and a water outlet 600. The negative pressure atomizing cylinder 300 is communicated with an external industrial waste gas inlet pipeline.
In the desulfurization and denitrification device 10 convenient to disassemble, assemble and maintain, the filtering and settling cylinder 100, the desulfurization and denitrification cylinder 200 and the negative pressure atomizing cylinder 300 are mutually independent, and are arranged together according to the connection relationship during desulfurization and denitrification; when the device is cleaned regularly, the three parts can be cleaned independently only by separating the negative pressure atomization cylinder 300 from the air inlet interface 210 and lifting the desulfurization and denitrification cylinder 200 to separate from the filtering and settling cylinder 100.
Specifically, as shown in fig. 3 and 4, the filtering and settling cylinder 100 includes an outer cylinder 110 and an inner cylinder 120, the inner cylinder 120 is fixedly accommodated inside the outer cylinder 110 through a connecting rod 130, and a filtering channel 140 is formed between the outer cylinder 110 and the inner cylinder 120; the bottom of the outer cylinder 110 forms a standing precipitation tank 150, the inside of the inner cylinder 120 forms a negative pressure water suction cavity 160, the bottom of the inner cylinder 110 is provided with a filtering through hole 170, and the negative pressure water suction cavity 160 is communicated with the standing precipitation tank 150 through the filtering through hole 170. The standing precipitation tank 150 is used for standing the absorbent solution so that the precipitate in the absorbent solution can be precipitated at the bottom of the standing precipitation tank 150. The absorbent solution after standing and precipitating enters the negative pressure water absorption cavity 160 through the filter through hole 170 to wait for being reused.
As shown in fig. 5 and 6, the outer surface of the negative pressure atomizing cylinder 300 and the inner surface of the desulfurization and denitrification cylinder 200 form an exhaust and drainage channel 700, and the negative pressure atomizing cylinder 300 is provided with a spray opening 310. The negative pressure atomizing cylinder 300 further comprises a negative pressure suction pipe 320, the negative pressure suction pipe 320 has a suction end 321 and a spraying end 322, the suction end 321 of the negative pressure suction pipe 320 is located in the negative pressure suction cavity 160, and the spraying end 322 of the negative pressure suction pipe 320 is located in the spraying port 310. The negative pressure suction pipe 320 can suck the absorbent solution in the negative pressure suction cavity 160 to the spray opening 310 by negative pressure, and atomize and spray the absorbent solution at the same time, which will be described in detail below.
It is emphasized that, as shown in fig. 6, the water suction end 321 of the negative pressure water suction pipe 320 is bent upward, and the spraying end 322 of the negative pressure water suction pipe 320 and the spraying port 310 both face the inner side surface of the desulfurization and denitrification cylinder 200 and are inclined downward.
The following explanation explains the working principle of the desulfurization and denitrification apparatus 10 which is convenient to disassemble, assemble and maintain:
before the start of desulfurization and denitrification, the water inlet 500 is opened and the water outlet 600 is closed, and an absorbent solution is injected into the filtration and precipitation cartridge 100. The injected absorbent will accumulate at the bottom of the filter settling cartridge 100 and the water level rises slowly and eventually enters the negative pressure suction chamber 160 through the filter through holes 170. When the absorbent solution passes through the water suction end 321 of the negative pressure water suction pipe 320, the water inlet 500 can be closed, and desulfurization and denitrification are started;
when the desulfurization and denitrification are started, the external industrial waste gas inlet pipeline is opened, the industrial waste gas rapidly gushes into the negative pressure atomizing cylinder 300 under the action of external pressure, and a higher pressure is formed in the negative pressure atomizing cylinder 300. Due to the pressure difference between the inside and the outside of the negative pressure atomizing cylinder 300, the industrial waste gas enters the air exhaust and drainage channel 700 from the inside of the negative pressure atomizing cylinder 300 through the atomizing nozzle 310. And because the aperture of the spray opening 310 is narrow, the air flow velocity is fast when the industrial waste gas passes through, and further, the pressure of the high-velocity flowing air flow at the spray opening 310 is reduced, namely, negative pressure is formed. At this time, the absorbent solution is sucked to the spray opening 310 through the negative pressure suction pipe 320 and sprayed out under the action of the air pressure, similar to the process of sucking water with a suction pipe in life. Due to the high velocity of the air stream at spray opening 310, the absorbent sprayed at spray opening 310 is torn into droplets by the high velocity air stream, i.e., atomization occurs. The contact area of the atomized and sprayed absorbent solution and industrial waste gas in the exhaust and drainage channel 700 is greatly increased, and the desulfurization and denitrification effects can be obviously improved;
after being sprayed, the absorbent solution slowly flows into the filtering channel 140 of the filtering and settling cylinder 100 along the inner side surface of the desulfurization and denitrification cylinder 200, and finally flows into the standing and settling tank 150 again. Among them, the absorbent participating in desulfurization and denitrification will produce precipitate, for example, calcium ion reacts with sulfate ion to produce calcium sulfate precipitate. The precipitate flows into the still standing precipitation tank 150 together with the absorbent solution. Because the flow rate of the absorbent solution is slow, the precipitate after desulfurization and denitrification of the absorbent solution will slowly sink in the standing precipitation tank 150. The clearer part of the absorbent solution will enter the suction chamber 160 again through the filter through holes 170 and participate in the next cycle. The desulfurized and denitrated industrial waste gas rises along the exhaust and drainage channel 700 and is finally discharged out of the desulfurization and denitrification cylinder 200 through the exhaust port 220;
when the cleaning and maintenance are carried out regularly, the water inlet 500 and the external industrial waste gas inlet pipeline are closed, and the water outlet 600 is opened to discharge the absorbent solution in the standing precipitation tank 150. Then, the negative pressure atomization cylinder 300 is drawn out from the air inlet interface 210 of the desulfurization and denitrification cylinder 200, and the desulfurization and denitrification cylinder 200 is lifted to be separated from the filtration and precipitation cylinder 100, so that the filtration and precipitation cylinder 100, the desulfurization and denitrification cylinder 200 and the negative pressure atomization cylinder 300 can be independently cleaned. Compared with other existing desulfurization and denitrification equipment, particularly integrally formed desulfurization and denitrification equipment, the desulfurization and denitrification equipment 10 convenient to disassemble, assemble and maintain is more suitable for periodic cleaning and maintenance.
In this embodiment, as shown in fig. 4, the filter screen 180 is disposed at the filter through hole 170, so that the precipitate in the absorbent solution can be better filtered, the absorbent solution entering the negative pressure water suction cavity 160 is purer, and the possibility of blockage of the negative pressure water suction pipe 320 and the spray nozzle 310 is reduced.
It is emphasized that the water suction end 321 of the negative pressure water suction pipe 320 is bent upward, so that the negative pressure water suction pipe 320 mainly affects the water flow in the upper half of the negative pressure water suction cavity 160 when absorbing the absorbent solution, thereby avoiding the influence on the absorbent solution in the lower half of the negative pressure water suction cavity 160 and the standing precipitation tank 150 as much as possible, and allowing the absorbent solution in the standing precipitation tank 150 to better stand and precipitate.
It is emphasized that the spraying end 322 and the spraying port 310 of the negative pressure suction pipe 320 face the inner side surface of the SOx/NOx control cylinder 200 and are inclined downwards, so that the absorbent and the industrial waste gas can be sprayed downwards and blocked by the inner side surface of the SOx/NOx control cylinder 200. With the blocking of the desulfurization and denitrification cylinder 200, the flow velocity of the industrial waste gas is reduced, so that the contact time of the industrial waste gas and the atomized absorbent can be prolonged, and the desulfurization and denitrification effect of the industrial waste gas is improved.
In one embodiment, as shown in fig. 6, a plurality of spray outlets 310 are formed on a side wall of the negative pressure atomizing cylinder 300, and the plurality of spray outlets 310 are uniformly distributed on the side wall of the negative pressure atomizing cylinder 300; correspondingly, the negative pressure suction pipe 320 comprises a primary negative pressure suction pipe 330 and a secondary negative pressure suction pipe 340, and the spraying end of the primary negative pressure suction pipe 330 is located below the spraying end of the secondary negative pressure suction pipe 340. Wherein, the number of the first-stage negative pressure suction pipes 330 is multiple, and a plurality of the first-stage negative pressure suction pipes 330 are distributed in an annular array by taking the central axis of the negative pressure atomizing cylinder 300 as the center; the number of the secondary negative pressure suction pipes 340 is plural, and the plural secondary negative pressure suction pipes 340 are distributed in an annular array with the central axis of the negative pressure atomizing cylinder 300 as the center. So, a plurality of nozzle 310 of bilayer can be to each direction blowout industrial waste gas and absorbent to improve SOx/NOx control efficiency, reach better SOx/NOx control effect.
In one embodiment, as shown in fig. 6, a flow-guiding air-blocking sheet 350 is further disposed on the side wall of the negative pressure atomizing cylinder 300, and a gap 800 is formed between the flow-guiding air-blocking sheet 350 and the inner side surface of the desulfurization and denitrification cylinder 200. The design of the flow directing baffle 350 has two benefits: firstly, the flow direction of the sprayed absorbent is guided, the sprayed absorbent is blocked and guided by the drainage gas barrier sheet 350, the absorbent is guided to the gap 800 and flows into the standing precipitation tank 150 along the side wall of the desulfurization and denitrification cylinder 200 or the filtration and precipitation cylinder 100, so that the flow rate of the absorbent flowing into the standing precipitation tank 150 is greatly reduced, the absorbent solution in the standing precipitation tank 150 is kept static as much as possible, and standing precipitation is facilitated; secondly, the rising of industrial waste gas is stopped, most of the exhaust and drainage channels 700 are blocked by the flow guide gas blocking pieces 350, and the industrial waste gas sprayed by the lower-layer spray nozzle 310 can be discharged through the exhaust port 220 only through the gap 800, so that the flow speed of the sprayed industrial waste gas is reduced, the time for desulfurization and denitration of the industrial waste gas is prolonged, and a better desulfurization and denitration effect is achieved.
In one embodiment, as shown in fig. 7, a fixing plate 230 is disposed at the air inlet interface 210 of the desulfurization and denitrification cylinder 200, and a cover plate 360 engaged with the fixing plate 230 is disposed on the negative pressure atomization cylinder 300. So, after a section of thick bamboo 200 of SOx/NOx control is worn to establish by a negative pressure atomizing section of thick bamboo 300 from the interface 210 that admits air, can rely on the cooperation of apron 360 and fixed plate 230, settle a negative pressure atomizing section of thick bamboo 300 in the cavity of SOx/NOx control section of thick bamboo 200 and the formation of filter sediment section of thick bamboo 100 stably. In some embodiments, the cover plate 360 is further provided with a positioning boss 361 (shown in fig. 5) and a reinforcing rib 362 (shown in fig. 7), wherein the positioning boss 361 is used for limiting the relative position of the cover plate 360 and the fixing plate 230, that is, the position of the negative pressure atomizing cylinder 300 accommodated in the desulfurization and denitrification cylinder 200; the reinforcing ribs 362 serve to increase the rigidity of the cover plate 360, making it less vulnerable.
In one embodiment, as shown in fig. 7, a forward stepped groove 190 is provided on the filtering and settling cylinder 100, and a reverse stepped groove 240 matched with the forward stepped groove 190 is provided on the desulfurization and denitrification cylinder 200. So, improve the cooperation in forward ladder groove 190 and reverse ladder groove 240, can be with the quick and accurate installation of SOx/NOx control section of thick bamboo 200 on filtering sediment section of thick bamboo 100, simultaneously, location and skid-proof function have been compromise with the cooperation in reverse ladder groove 240 to forward ladder groove 190.
It is also emphasized that: firstly, the spraying end 322 and the spraying port 310 of the negative pressure water suction pipe 320 face the inner side surface of the desulfurization and denitrification cylinder 200, so that the sprayed absorbent is gathered into small water drops on the inner side surface of the desulfurization and denitrification cylinder 200 and slowly flows into the standing and settling tank 150, and the absorbent can be better kept standing and settled by flowing down along the inner side surface of the desulfurization and denitrification cylinder 200 compared with the mode that the atomized absorbent falls into the standing and settling tank 150 like rain; secondly, the spraying end 322 and the spraying opening 310 are inclined downwards, so that the rising speed of the industrial waste gas is reduced, the contact time of the industrial waste gas and the atomized absorbent is prolonged, and the desulfurization and denitrification effects of the industrial waste gas are improved; thirdly, the water suction end 321 of the negative pressure water suction pipe 320 is bent upwards, so that when the negative pressure water suction pipe 320 sucks the absorbent solution, the absorbent solution in the standing precipitation tank 150 can be kept static as much as possible, and the standing precipitation effect is better.
In conclusion, the desulfurization and denitrification equipment 10 convenient to disassemble, assemble and maintain can make the periodic cleaning and maintenance of the desulfurization and denitrification equipment more convenient.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
