Description

Dust removal system

Technical Field

The invention belongs to the field of environment-friendly equipment, and particularly relates to a dust removal system.

Background

As is well known, the dust removal techniques generally include mechanical dust removal, wet dust removal, electrostatic dust removal, and bag dust removal. The mechanical dust removal is to separate dust by utilizing the gravity settling, inertia or centrifugal force of the dust, the dust removal efficiency is generally below 90 percent, the dust removal efficiency is low, the resistance is low, and the energy is saved. The wet dust removal is to separate dust in dust-containing gas into liquid by utilizing a gas-liquid contact washing principle so as to remove the dust in the gas, and the existing wet dust removal is generally combined into two forms of water bath and spraying. Firstly, the dust-containing gas is pressed into a water tank filled with water with a certain height by utilizing the suction force of a high-pressure centrifugal fan, and is introduced below the water surface, and the water bath can adsorb a part of dust in the water. After the uniform distribution and the flow division, the gas flows from bottom to top, the high-pressure spray head sprays water mist from top to bottom, the rest dust particles are collected, and small fibrous substances are easy to block the spray head in the spraying process. Although the dust remover has high dust removal efficiency on dust with the particle size of less than 5 mu m, the filtering efficiency can reach more than 85 percent, but the filtering efficiency can not reach more than 92 percent, and the service life is generally 5 to 8 years. And the water consumption is large, about 1 ton/hour, and the pipeline is easy to block, moreover, the method is easy to generate secondary pollution due to large water consumption, and needs secondary sewage treatment. The electrostatic dust collection is to pass the dust-containing gas through a strong electric field to charge dust particles, and when the dust-containing gas passes through a dust collection electrode, particles with positive/negative charges are respectively adsorbed by a negative/positive electrode plate, so that the dust in the gas is removed. The electrostatic dust collector has high dust collection efficiency, but the dust collection efficiency is greatly influenced by dust specific resistance, so that the dust collection efficiency is easy to be unstable. The bag type dust collector collects solid particles in dust-containing gas by using a fiber filter material to form a filter dust cake, and fine dust particles are further filtered by the filter dust cake to achieve the purpose of high-efficiency dust removal. The bag type dust removal technology can stably achieve very high dust removal efficiency, and the dust discharge amount can reachTo 5mg/m³The dust removal efficiency is not affected by the dust characteristics such as dust specific resistance. Generally, dust (i.e. inhalable particles) with the particle size of less than 10 microns has a great influence on human health, and the bag type dust collector has high separation efficiency on the inhalable particles. The bag type dust collector is used for treating normal temperature flue gas<The application range in the pollution is gradually enlarged at 120 ℃, and with the further development of high-temperature resistant filter materials, pulse ash removal and other technologies, the bag type dust collector is more and more widely applied to the field of treating high-temperature and high-concentration flue gas by virtue of excellent dust removal performance. But the cost of bag-type dust removal is higher, needs regularly to change and crosses the filter bag, and a filter bag is in the use moreover, because the aperture of crossing the filter bag is being stained with the particulate matter and convulsions to changing the back, its filter effect reduces gradually.

Referring to fig. 1, fig. 1 is a schematic front view of a dust removing system according to the present invention. As shown in figure 1, the dust removal system of the invention comprises three parts of an air intake device 1, a dust removal water tank 2 and an exhaust duct 3:

the air intake device 1 may be a fan or other mechanical device with air suction function, and its structure and function are common knowledge, and therefore are not described herein. For the sake of combination with the following mechanism and for easy understanding, it is emphasized that the air intake device 1 comprises a first air intake opening 11 and a first air outlet opening 12.

The dust removal water tank 2 comprises a second air inlet 21, a plurality of water tank chambers (not shown) and a second air outlet 22, wherein liquid is filled in the water tank chambers, and when the dust particles which do not need to be subjected to chemical reaction are treated, the liquid filled in the water tank chambers is water. The water tank cavity comprises a first baffle 23 and a second baffle 24, the first baffle 23 and the second baffle 24 divide the water tank cavity into a first water tank chamber 25, a second water tank chamber 26 and a third water tank chamber 27, and the first water tank chamber 25, the second water tank chamber 26 and the third water tank chamber 27 are communicated. It should be emphasized that the number of the first baffle 23 and the number of the second baffle 24 may be one or more, and accordingly, the number of the first tank chamber 25, the second tank chamber 26 and the third tank chamber 27 may be changed according to the number of the first baffle 23 and the second baffle 24, and furthermore, the arrangement order of the plurality of first baffles 23 and the plurality of second baffles 24 may be alternately arranged regularly or irregularly.

Exhaust pipe 3 includes third air inlet 31, a plurality of baffle 33 and third air outlet 32 of airing exhaust, a plurality of baffle 33 of airing exhaust sets up in exhaust pipe 3, and with exhaust pipe 3's inner wall fixed connection. It should be emphasized here that the exhaust baffle 33 disposed in the exhaust duct 3 can let the air be exhausted from the third air inlet 31 to the third air outlet 32.

As can be seen from the above, the air intake device 1, the dust removal water tank 2 and the exhaust pipe 3 are respectively communicated with the second air inlet 21 through the first air outlet 12, and the second air outlet 22 is communicated with the third air inlet 31 to obtain air flow among the three.

For convenience of understanding, the working principle of the present design will be described by taking the number of the first baffles 23 as one, the number of the second baffles 24 as one, and the arrangement of the first baffles 23 and the second baffles 24 as an example: the air intake device 1 is started, polluted gas is sucked from the first air inlet 11, flows out from the first air outlet 12, enters the second air inlet 21, is filtered by the first water tank chamber 25, the second water tank chamber 26 and the third water tank chamber 27, enters the third air inlet 31 from the second air outlet 22, and is released after reaching the standard from the third air outlet 32 after being filtered by the exhaust baffle 33.

The specific arrangement method of the two baffles is described as follows:

referring to fig. 1, as shown in fig. 1, the first baffle 23 is fixedly connected to the sidewall of the water tank chamber, a first gap 231 is disposed between the top end of the first baffle 23 and the top of the water tank chamber, a second gap 232 is disposed between the bottom end of the first baffle 23 and the bottom of the water tank chamber, a water level line of the liquid contained in the water tank chamber is higher than the bottom end of the first baffle 23, and the water level line is lower than the top end of the first baffle 23. After entering the first chamber 25, the gas partially contacts the liquid at the bottom of the dust removing water tank 2 with the gas flow, and then the gas rises with the gas flow and enters the second chamber 26 through the first gap 231, please note that: 1: when the polluted air flow enters the first water tank chamber 25, the polluted air flow is directly released at the second air outlet 21 instead of being communicated below the liquid level like a water bath in the prior art; 2: because the second gap 232 is provided, the liquid levels of the first chamber 25 and the second chamber 26 are at the same height and are communicated with each other, and the liquid level generates a water curtain, a water film and water shower in the first chamber 25 due to the impact of the air flow.

The second baffle plate 24 is also fixedly connected with the side wall of the water tank cavity, the top end of the second baffle plate 24 is fixedly connected with the top of the water tank cavity, a third gap 241 is arranged between the bottom end of the second baffle plate 24 and the bottom of the water tank cavity, and the water level line of the liquid contained in the water tank cavity is lower than the bottom end of the second baffle plate 24. After entering the second water tank chamber from the first gap 231, the gas enters the third water tank chamber 27 from the third gap 241 along with the descending of the gas flow, and because the water level line of the liquid contained in the water tank chamber is lower than the bottom end of the second baffle 24, a space still exists between the bottom end of the second baffle 24 and the page, when the gas enters the third water tank chamber 27 from the third gap 241, the corresponding part of the gas is contacted with the liquid, and due to the impact of the gas flow, the liquid not only generates a water curtain, a water film and water shower in the second water tank chamber 26, but also generates the water curtain, the water film and the water shower in the third water tank chamber 27.

In a preferred embodiment said first baffle 23 is parallel to said second baffle 24, said first baffle 23 and said second baffle 24 being perpendicular to the level of the liquid contained in said tank chamber.

In order to further purify the polluted air, the water tank cavity further comprises a third baffle 28, the third baffle 28 is arranged in the water tank three-chamber 27, the third baffle 28 is fixedly connected with the side wall of the water tank cavity, the top end of the third baffle 28 is fixedly connected with the top of the water tank cavity, and the water level line of the liquid contained in the water tank cavity is lower than the bottom end of the third baffle 28. The third baffle 28 divides the tank three chamber 27 into two chambers, namely a tank three chamber first sub-chamber 271 and a tank three chamber second sub-chamber 272, so that the polluted air is subjected to the water film filtration again through the tank three chamber first sub-chamber 271 and the tank three chamber second sub-chamber 272, respectively. Also, it should be noted that the number of the third baffle 28 may be one or more, and accordingly, the number of the tank three-chamber first subchamber 271 and the tank three-chamber second subchamber 272 may also be changed according to the number of the third baffles 24.

In a preferred embodiment, the cross section of the third baffle 28 is "L" shaped, the third baffle 28 includes a first sub-vertical plate 281 and a first sub-transverse plate 282, the first sub-vertical plate 281 is fixedly connected with the side wall of the tank chamber, the top end of the first sub-vertical plate 281 is fixedly connected with the top of the tank chamber, the bottom end of the first sub-vertical plate 281 is fixedly connected with one end of the first sub-transverse plate 282, a fourth gap 283 is arranged between the other end of the first sub-transverse plate 282 and the side wall of the tank chamber, the first sub-vertical plate 281 is parallel to the second baffle 24, and the first sub-transverse plate 282 is parallel to the level of the liquid contained in the tank chamber. As shown in fig. 1, in this embodiment, the first subchamber 271 of the three-chamber tank is arranged below, the second subchamber 272 of the three-chamber tank is arranged above, and the two subchambers are arranged vertically, so that the gas can flow toward the exhaust pipe 3 through the fourth gap 283 to be further filtered.

In order to better embody the function of the first sub-transverse plate 282, the air is prevented from directly entering the exhaust duct 3 after directly passing through the third gap 241, and the length of the first sub-transverse plate 282 is greater than the aperture of the second outlet 22. Therefore, the gas bypasses the first sub-diaphragm 282, so that two filtrations can be performed in the tank third chamber, the first sub-chamber 271 and the tank third chamber, the second sub-chamber 272.

In one embodiment, the height of the bottom end of the second baffle 24 is lower than the height of the bottom end of the third baffle 28, so that the space of the tank three-chamber first sub-chamber 271 is larger than the height of the tank three-chamber second sub-chamber 272, and conversely, if the height of the bottom end of the second baffle 24 is higher than the height of the bottom end of the third baffle 28, then some gas directly enters the tank three-chamber second sub-chamber 272 from the narrow passage of the tank three-chamber first sub-chamber 271 after contacting the liquid surface, so that the function of the third baffle 28 is not well reflected.

In the exhaust duct 3, a plurality of the exhaust baffles 33 are arranged in a multilayer cross manner. The multilayer crossing arrangement may be regular or irregular. Most preferably, all the air discharge baffles 33 are parallel to the first sub-cross plate 282, and the air discharge baffles 33 may be fixed left and right, that is, the air passes through the air discharge baffles 33 in a curved manner while passing through the air discharge baffles 33 in the air discharge duct 3 during the process of entering the third air outlet 32 from the third air inlet 31.

In the above process, the lengths of the plurality of exhaust baffles 33 are all smaller than the pipe diameter of the exhaust duct 3, and the sum of the lengths of any two exhaust baffles 33 is greater than the pipe diameter of the exhaust duct 3.

The dust-removing water tank 2 further comprises a water inlet (not shown) and a water outlet 29, the water outlet 29 is generally arranged in the area close to the bottom of the dust-removing water tank 2, the diameter of the water outlet 29 is larger, the shape of the water outlet is not limited, and the water outlet 29 can be used for draining water and cleaning sediments.

For ease of understanding, a best and simplest embodiment will now be described.

With reference to fig. 1, the dust removing system is configured as described above, wherein the number of the first baffle 23, the second baffle 24 and the third baffle 28 is one, the first baffle 23 and the second baffle 24 are parallel and perpendicular to the liquid level, the third baffle 28 has an L-shaped cross section, the cross sections of the plurality of exhaust baffles 33 are arranged crosswise, the sum of the lengths of two adjacent exhaust baffles 33 is greater than the pipe diameter of the exhaust duct 3, any exhaust baffle 33 is parallel to the first sub-horizontal plate 282, and the length of the first sub-horizontal plate 282 is greater than the caliber of the second air outlet 22. The liquid in the dedusting water tank 2 is water.

Continuing with FIG. 1, note that the arrows indicate: the air inlet device 1 is started to suck the polluted air of the first air inlet 11 into the air inlet device 1, the polluted air is directly connected into the dust removal water tank 2 through the second air inlet 21 through the first air outlet 12, and metal particles are carried along to directly contact the water surface, instead of directly pumping the polluted air into the water to pass through a water bath like a common dust removal method. Large particles sink into the dust removal water tank 2 rapidly under the action of the inertia of the air flow, and the water in the first water tank chamber 25 generates a water curtain, a water film and water shower by the driving force generated by the air flow. Most of the metal and nonmetal in the polluted air flow are mixed with water, so that the primary effect of dust removal is achieved.

According to the experiment, a small part of fine particles can not be removed, and the fine particles need to enter the second water tank 26, and secondary dust removal is carried out according to the principle. The second chamber 26 of the water tank adopts inverted airflow guide, and the water film and water spray generated at the top can easily collect fine dust in water.

According to the principle of upward movement under the action of the fine dust airflow, the airflow enters the water tank three chamber 27 again, and the third dust removal is performed according to the principle as described above. After the fine dust is filtered again at the bottom of the third baffle and the top of the third chamber of the water tank, the dust content is fine and can be discharged, so that the dust content of the polluted air flow directly entering the exhaust pipe and treated for three times is low, the air flow flows out of the second air outlet 22 and directly enters the baffles arranged on the exhaust pipe 3 through the third air inlet 31, the passing air flow with water forms an irregular water film on the exhaust pipe, the polluted air flow is finally and finely filtered, the situation that no dust exists at the third air outlet 32 is ensured, and the filtering rate is as high as 99.9-99.99%.

The above structure completes the process of changing the polluted air into clean air after the whole operation in the dust removing system.

In order to better understand the effect of the present invention, a dust removing system in the prior art is specifically compared with a dust removing system in the present invention under the same experimental conditions, which is specifically as follows.

Therefore, the dust removal system has the advantages of low filtering cost, good filtering effect, no need of frequent replacement of parts of the filtering equipment, difficult damage, very low maintenance cost and easy cleaning of precipitates.

It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
