Description

TECHNICAL FIELD

[0001] The application relates to the technical field of flue gas purification, and in particular to a flue gas purifying atomizer all-in-one machine. BACKGROUND

[0002] A large amount of particulate dust is generated in industrial production, and the untreated dust has different hazards to people, plants or climate. When industrial flue gas is discharged, the particulate impurities in the flue gas need to be treated.

[0003] In the prior art, bag-type dust removal, electrostatic dust removal and spray dust removal are generally used to remove the particulate impurities in the flue gas. The first two methods only have dust removal effect and cannot eliminate harmful substances in the gas. The spray dust removal can filter harmful gases contained in the gas while removing dust. In view of the above problems, a kind of ultrasonic synchronous desulfurization and dust removal integrated device is provided in authorization announcement No. CN108671723B. The dust removal integrated device uses the atomizing spray method to remove dust from the flue gas. The liquid is rapidly atomized to form a large amount of atomized water vapor by using the ultrasonic atomization method. The atomized water vapor is sprayed out through the atomizing nozzle to adsorb the particulate impurities in the flue gas. Then the dust is removed by gravity.

[0004] Although the above method can filter harmful gases contained in the gas while removing dust, the flue gas maintains a horizontal laminar flow state after entering the device. The outer layer of flue gas can achieve good treatment effect near the inner wall of the device. The inner layer of flue gas wrapped by the outer layer of flue gas has a small contact area with water vapor, resulting in poor treatment effect of the inner layer of flue gas. SUMMARY

The technical effect of mixing and blending the inner and outer layers of flue gas by using a telescopic cylinder to pull an elastic membrane to increase the longitudinal suction force inside and disperse the gas longitudinally is achieved.

[0075] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the use of the terms "and / or" includes a combination of one or more of the associated listed items.

[0076] By setting the elastic membrane 410 and the second telescopic cylinder 430, the flue gas enters the flue gas treatment bin 200 from the air inlet 100, and the flue gas maintains a horizontal laminar flow state when entering. The inner layer gas flows wrapped by the outer layer gas, so that the inner layer gas is not easy to mix with the water mist. The end close to the elastic membrane 410 is the outer layer gas, and at the same time, the two second telescopic cylinders 430 are started to contract, thereby pulling the two elastic membranes 410 away from the outer layer gas. The negative pressure is increased in the interior, a negative pressure area is formed at the elastic membrane 410, the gas flows to the negative pressure area due to the compensation of air pressure difference, a longitudinal suction force is generated to make the gas disperse longitudinally, the flow speed of the gas is slowed down, and the inner layer gas is mixed with the outer layer gas. Then the two second telescopic cylinders 430 are started to extend, thereby pushing the elastic membrane 410 to send the mixed gas into the flue gas treatment bin 200. In this way, the reciprocating motion is carried out, so that the inner layer gas can be uniformly contacted with the water mist.

[0077] Example 1: As Figures 1-20 As shown, this application discloses an integrated atomizer for flue gas purification, including a flue gas treatment chamber 200 and a spraying device; the spraying device sprays into the flue gas treatment chamber 200; the flue gas treatment chamber 200 is rectangular, with openings at both ends along its length to form an air inlet 100 and an air outlet 300.

[0078] It also includes a mixing component 400; the mixing component 400 is used to mix the flue gas entering from the air inlet 100; the flue gas treatment chamber 200 has openings on both sides along its length.

[0079] like Figures 1-5 As shown, the mixing component 400 includes a fixed chamber 420, an elastic membrane 410, and a second telescopic cylinder 430;

[0080] The fixed chamber 420 is rectangular and hollow inside; there are two fixed chambers 420, which are respectively fixed on both sides of the length direction of the flue gas treatment chamber 200; the overlapping surface of the fixed chamber 420 and the flue gas treatment chamber 200 is connected, and the end faces of the fixed chamber 420 that do not overlap with the two sides of the length direction of the flue gas treatment chamber 200 are closed.

[0081] The elastic membrane 410 is fixed inside the fixed chamber 420 on the side near the opening of the flue gas treatment chamber 200; the outer periphery of the elastic membrane 410 is airtightly fixed to the inner wall of the fixed chamber 420; the elastic membrane 410 divides the fixed chamber 420 into two sealed cavities, one facing the opening of the flue gas treatment chamber 200 and the other facing the closed end of the fixed chamber 420.

[0082] The second telescopic cylinder 430 is fixed in the cavity facing the closed end of the fixed chamber 420; the telescopic end of the second telescopic cylinder 430 is fixedly connected to the side of the elastic membrane 410 facing the closed end cavity of the fixed chamber 420.

[0083] The fume purifying atomizer all-in-one machine of the embodiment of the application is used in practice: the flue gas enters the flue gas treatment bin 200 from the air inlet 100, and the flue gas maintains a horizontal laminar flow state when entering, the inner layer gas flows while being wrapped by the outer layer gas, so that the inner layer gas is not easy to mix with the water mist, the outer layer gas is close to one end of the elastic membrane 410, and the two second telescopic cylinders 430 are started to contract at the same time, so as to pull the two elastic membranes 410 away from the outer layer gas, increase the negative pressure in the inside, form a negative pressure area at the elastic membrane 410, and the gas flows to the negative pressure area due to the compensation of the air pressure difference, a longitudinal suction force is generated to make the gas disperse longitudinally, the flow speed of the gas is slowed down, and the inner layer gas is mixed with the outer layer gas, the two second telescopic cylinders 430 are started to extend, and then the elastic membrane 410 is pushed to send the mixed gas into the flue gas treatment bin 200, and the reciprocating motion is performed, so that the inner layer gas can be uniformly contacted with the water mist, and the dust removal effect is improved.

[0084] The technical scheme in the embodiment of the application has at least the following technical effects or advantages:

[0085] The problem that, in the prior art, the inner layer flue gas wrapped by the outer layer flue gas has a small contact area with the atomized water vapor due to the fact that the flue gas maintains a laminar flow state after entering the device, and the inner layer flue gas treatment effect is poor, is solved, and the technical effect of mixing the inner layer flue gas with the outer layer flue gas by using the telescopic cylinder to pull the elastic membrane 410 to increase the longitudinal suction force in the inside and make the gas disperse longitudinally is achieved.

[0086] In actual use, it is found that although the above embodiment can mix the inner layer gas with the outer layer gas, the elastic membrane 410 needs to perform a push-pull motion at the same time, and since the flue gas still maintains a flow state in the flue gas treatment bin 200, when the two elastic membranes 410 are pulled to the limit position at the same time and pushed back, a pause occurs, at this time, the flue gas passing through is not sucked into the negative pressure area of the elastic membrane 410, and therefore this part of flue gas is discharged upward without being treated, which affects the efficiency of gas purification, and therefore, the above problem is further improved, and the specific improvement is as follows:

[0087] As shown in Figure 6 and Figure 7 , the fixed bin 420 is divided into a plurality of longitudinal cavities by a partition plate; the number of the plurality of longitudinal cavities is an even number greater than 2;

[0088] An elastic membrane 410 is fixed in each longitudinal cavity close to the opening of the flue gas treatment bin 200;

[0089] The elastic membrane 410 in one longitudinal cavity is pulled by a second telescopic cylinder 430;

[0090] As shown in Figures 8-11As shown, the two longitudinal cavities opposite to the opening are a group; the second telescopic cylinders 430 in the same group of longitudinal cavities work alternately, when one second telescopic cylinder 430 completes the telescopic action, the other second telescopic cylinder 430 starts the telescopic action.

[0091] In actual use, on the basis of the above embodiment, when the flue gas enters the flue gas treatment bin 200, the second telescopic cylinders 430 in the same group of longitudinal cavities start to work alternately, when one second telescopic cylinder 430 completes the telescopic action, the other second telescopic cylinder 430 starts the telescopic action immediately, and the two elastic membranes 410 are kept in an alternating use state, and so on, so that the multiple elastic membranes 410 are kept in an alternating use state, so that the flue gas can enter the negative pressure area generated by the elastic membrane 410 continuously, and reciprocate to purify and treat the entering flue gas, thereby improving the efficiency of gas treatment.

[0092] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0093] The problem that the pushing and pulling of the elastic membrane 410 at the corresponding position causes staggered areas of flue gas, part of the flue gas is dispersed, and the flue gas discharge time is increased is solved, and the technical effect of providing multiple elastic membranes 410 to make the elastic membrane 410 at the staggered position perform pushing and pulling movement, so that the flue gas is not dispersed and the discharge efficiency is improved is achieved.

[0094] In actual use, the atomizing nozzle 560 is generally installed at the top of the flue gas treatment bin 200, and a vertical spraying mode from top to bottom is adopted. This spraying mode makes the spraying position fixed and unchanged, and cannot follow the movement state of the flue gas for spraying, so that most of the sprayed water mist sinks without contacting the smoke, resulting in serious waste of water resources and poor dust removal effect.
