Description

Technical Field

[0001] The present application relates to the technical field of waste gas treatment, and in particular to an organic waste gas treatment device and method. Background Art

[0002] Organic waste gas refers to gases containing hydrocarbons and their derivatives, which usually come from various industrial production processes, the use of chemicals, transportation, and some daily life activities. The generation of organic waste gas not only pollutes the environment, but many organic compounds are harmful to human health, so appropriate measures need to be taken to control and reduce emissions. Among them, after the waste gas is separated, the tar and smoke in the waste gas need to be collected and filtered, and then the subsequent incineration treatment process is carried out.

[0003] Referring to the Chinese patent application document with publication number CN116510421A and publication date August 1, 2023, entitled A Type of Asphalt Waste Gas Treatment Device, the exhaust gas is decomposed by the centrifugal force of the cyclone device, and the tar produced by the decomposition adheres to the surface of the flue gas cyclone device. The tar is thrown out to the inner wall of the oil remover body under the action of centrifugal force, and flows downward along the inner wall of the oil remover body and converges on the heater, thereby reducing the tar on the inner wall of the oil remover body and the surface of the flue gas cyclone device.

[0004] Referring to the above technical solution, in order to prevent the tar generated during the decomposition of the exhaust gas from adhering to the surface of the cyclone smoke exhaust component, the tar is thrown onto the inner wall of the degreaser body under the action of centrifugal force. However, the tar itself has a certain adhesion force and it takes a long time to slide onto the heater. Therefore, when the smoke decomposed in the exhaust gas is discharged from the outlet, some tar molecules will be discharged from the outlet together with the smoke, reducing the initial decomposition quality of the organic waste gas.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 7, the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0028] In the first aspect, the present application provides an organic waste gas treatment device, which adopts the following technical solution: Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The present embodiment provides an organic waste gas treatment device, including a treatment tank 1, a driving source 2 is installed at the inner bottom of the treatment tank 1, a waste gas collecting chamber 11 is arranged inside the treatment tank 1, a waste gas cyclone blade 3 is installed on the driving mechanism through a sleeve 4, and the waste gas collecting chamber 11 and the treatment tank 1 are concentric axes.

[0029] A sleeve 4 is installed at the executive end of the driving source 2. The interior of the sleeve 4 is set as a hollow structure and passes through the center of the exhaust gas collection chamber 11. A telescopic cylinder 41 that passes through the bottom of the sleeve 4 is rotatably connected to the bottom of the sleeve 4. A connecting tube 42 is installed at the executive end of the telescopic cylinder 41. The connecting tube 42 is axially installed inside the sleeve 4. A first row of pipes 43 are sleeved on the top of the connecting tube 42 through an annular groove. An annular groove is opened on the shaft. The top of the connecting tube 42 is sleeved inside the annular groove. An elastic baffle 431 is arranged around the edge of the first row of pipes 43. The elastic baffle 431 is used to scrape off the tar sticking to the inner side of the top of the treatment tank 1. A shrinking ring 12 is arranged around the upper part of the treatment tank 1. The shrinking ring 12 assists the elastic baffle 431 to shrink or expand.

[0030] A circular array of vertical strip holes is opened on the outer wall of the connecting tube 42, a connecting block 44 is fixedly installed inside the sleeve 4, the vertical strip holes on the connecting tube 42 pass through the edge of the connecting block 44, the middle part of the connecting tube 42 reciprocates and rises and falls on the connecting block 44, a second row of pipes 45 is fixedly installed on the connecting block 44 through an axis, and the connecting barrel and the second row of pipes 45 reciprocate and rise and fall driven by the telescopic cylinder 41.

[0031] There is a ball joint between the execution end of the telescopic cylinder 41 and the connecting tube 42. The top of the connecting tube 42 is connected to the first row of pipes 43 through an annular groove. When the connecting block 44 drives the connecting tube 42 to rotate, the telescopic cylinder 41 and the first row of pipes 43 will not be synchronously mobilized to rotate, thereby reducing the transmission force of the driving source 2.

[0032] When the first row of smoke pipes 43 rises, the elastic baffle 431 moves upward synchronously, and the elastic baffle 431 shrinks under the resistance of the shrinking ring 12. When the first row of smoke pipes 43 descends, the elastic baffle 431 breaks away from the shrinking ring 12, and the tar on the upper inner wall of the processing tank 1 is scraped off and collected centrally. When the smoke is discharged, the amount of tar contained in the smoke is reduced.

[0033] Reference Figure 2 A heating chamber 13 is provided between the processing tank 1 and the waste gas collecting chamber 11 , a heating plate 14 is installed on the inner wall of the processing tank 1 , and a plurality of gas circulation inlets 111 are provided at the lower part of the waste gas collecting chamber 11 .

[0034] The heating plate 14 heats the concentrated tar in the heating chamber, so that a small amount of flue gas contained in the tar is separated from the tar and transported to the exhaust gas collection chamber 11 again through the gas circulation inlet 111.

[0035] Reference Figure 3 and Figure 4 The sleeve 4 has a circular array of triangular scrapers 46, which are used to scrape off the tar adhered to the inner wall of the first row of pipes 43.

[0036] When the first row of pipes 43 return to their original positions, the triangular scraper 46 contacts the inner wall of the first row of pipes 43 , and driven by the rotation of the sleeve 4 , scrapes off the tar on the inner wall of the first row of pipes 43 , and moves downward along one side wall of the triangular scraper 46 to the elastic baffle.

[0037] Reference Figure 2 and Figure 3 A curved spiral scraper 432 is installed around the outer wall of the first row of pipes 43.

[0038] When the first row of pipes 43 moves upward driven by the telescopic cylinder 41 and the connecting tube 42 until the curved spiral scraper 432 on the first row of pipes 43 contacts the inner wall of the second row of pipes 45, the curved spiral scraper 432 scrapes off the tar on the inner wall of the second row of pipes 45 under the high-speed rotation of the first row of pipes 43.

[0039] Reference Figure 2 A tar collecting bin 15 is provided at the lower part of the heating bin 13 .

[0040] After being collected and heated, the tar flows into the tar collection bin 15 .

[0041] The implementation principle of an organic waste gas treatment device in the embodiment of the present application is: When the exhaust gas is collected centrally, the exhaust gas enters the exhaust gas collecting chamber 11 inside the treatment tank 1 through the air inlet. The exhaust gas cyclone fan rotates under the drive of the driving source 2 to generate centrifugal force, and the centrifugal force spirals the exhaust gas upward. Part of the exhaust gas completes tar separation inside the exhaust gas cyclone blades 3, and the other part of the exhaust gas is transported to between the first row of smoke pipes 43 and the second row of smoke pipes 45 through the exhaust gas cyclone blades 3.

[0042] When the waste gas is decomposed, the second row of pipes 45 rotates synchronously with the sleeve 4, and the waste gas is decomposed into tar and smoke under the action of centrifugal force. Most of the smoke passes through the second row of pipes 45 and is discharged from the exhaust port, while the tar adheres to the inner wall of the second row of pipes 45 and the inner wall of the upper part of the treatment tank 1.

[0043] When scraping off the tar, the first row of pipes 43 moves axially along the sleeve 4 under the reciprocating extension and contraction drive of the telescopic cylinder 41, and the elastic baffle 431 shrinks under the limit of the shrinking ring 12 when it rises, and expands when the elastic baffle 431 descends and separates from the shrinking ring 12, so as to scrape off the tar on the upper inner wall of the processing tank 1 and collect it in the heating chamber 13.

[0044] When the tar and the flue gas are separated again, the heating plate 14 heats the concentrated and collected tar to separate the tar and the flue gas again. The flue gas enters the exhaust gas collection chamber 11 through the gas circulation inlet 111, and the exhaust gas cyclone blades 3 circulate the flue gas once to the first row of flues 43 and the second row of flues 45 and discharge it from the exhaust port on the top of the treatment tank 1.

[0045] In a second aspect, the present application provides an organic waste gas treatment method, which is applied to an organic waste gas treatment device in the first aspect, and the treatment method includes: S1, waste gas collection: waste gas enters the waste gas collection chamber 11 inside the treatment tank 1 through the air inlet, and the waste gas cyclone blades 3 spirally transport the waste gas upward, a part of the waste gas is separated from tar inside the waste gas cyclone blades 3, and the other part of the waste gas is transported to between the first row of smoke pipes 43 and the second row of smoke pipes 45 through the waste gas cyclone blades 3; S2, waste gas decomposition: the second row of pipes 45 rotate synchronously with the sleeve 4, and the waste gas is decomposed into tar and smoke under the action of centrifugal force. Most of the smoke passes through the second row of pipes 45 and is discharged from the exhaust port, while the tar adheres to the inner wall of the second row of pipes 45 and the inner wall of the upper part of the processing tank 1; S3, tar scraping: the first row of tobacco pipes 43 move axially along the sleeve 4 under the reciprocating extension and contraction of the telescopic cylinder 41, and the elastic baffle 431 contracts when rising and expands when descending to scrape the tar on the upper inner wall of the processing tank 1 downwards and collect it in the heating chamber 13; S4, tar and flue gas are separated again: the heating plate 14 heats the concentrated and collected tar to separate the tar and flue gas again, and the flue gas enters the exhaust gas collection chamber 11 through the gas circulation inlet 111, and the flue gas is circulated and transported.

[0046] The first row of smoke pipes 43 rises and falls driven by the telescopic cylinder 41 and the connecting tube 42. When rising, the elastic baffle 431 moves upward synchronously, and the elastic baffle 431 shrinks under the resistance of the shrinking ring 12. When the first row of smoke pipes 43 descends, the elastic baffle 431 breaks away from the shrinking ring 12, and the tar on the upper inner wall of the processing tank 1 is scraped off and collected centrally. When the smoke is discharged, the amount of tar contained in the smoke can be reduced, thereby improving the initial decomposition quality of the organic waste gas.

[0047] In step S3, when the first row of tobacco pipes 43 return to their original positions, the inclined surface of the triangular scraper 46 contacts the inner wall of the first row of tobacco pipes 43, and the triangular scraper 46 rotates synchronously with the sleeve 4. The inclined surface of the triangular scraper 46 scrapes the tar adhered to the inner wall of the first row of tobacco pipes 43 to the bottom of the elastic baffle 431, so that it enters the heating chamber 13.

[0048] The triangular scraper 46 scrapes off the tar adhered to the inner wall of the first row of pipes 43, and collects the tar inside the heating chamber 13 through the centrifugal force of its own rotation. When the smoke is discharged, the tar on the internal parts of the processing tank 1 is further reduced, and the tar content when the smoke is discharged is reduced.

[0049] In step S3, when the first exhaust pipe 43 slides axially upward under the drive of the telescopic cylinder 41, the curved spiral scraper 432 contacts the inner wall of the second exhaust pipe, scrapes off the tar adhering to the inner wall of the second exhaust pipe, and slides along the curved spiral scraper 432 to the elastic baffle 431. When the elastic baffle 431 contacts the shrinking ring 12, the tar on the upper surface of the elastic baffle 431 is scraped off onto the heating plate 14.

[0050] The curved spiral scraper 432 scrapes off the tar on the inner wall of the second exhaust hopper, and collects the tar inside the heating chamber 13 through the up and down movement of the elastic baffle 431. When the smoke is discharged, the tar on the internal parts of the processing tank 1 is further reduced, reducing the tar content when the smoke is discharged.

[0051] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
