Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to an environmentally friendly treatment device for chemical waste gas. Background Technology

[0002] Waste gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. Common waste gas purification methods include factory flue gas purification, workshop dust gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, and chemical waste gas purification.

[0003] During the treatment of waste gas generated by chemical plants, the space and depth of the treatment area are generally large, and relying solely on pumping to transport the waste gas is insufficient. This not only leads to weaker flow of the waste gas as it goes up, resulting in poorer contact with filter media using traditional static and fixed methods, but also causes turbulence due to excessive pressure in the initial pumped waste gas, resulting in poor treatment effect.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides an environmental protection treatment device for chemical waste gas, including a treatment tank 1. Both the front and rear sides of the treatment tank 1 are fixed with cleaning covers with sealing gaskets by screws, which facilitates the cleaning and replacement of the components inside the treatment tank 1. The cleaning covers are embedded with tempered glass, which provides effective pressure resistance and protection, and also facilitates observation of the internal waste gas treatment status from the outside. An air inlet pipe 2 is connected to the outside of the bottom of the treatment tank 1, and an exhaust pipe 3 is connected to the tank cover of the treatment tank 1. An inner cylinder 4 is vertically arranged inside the treatment tank 1, and both the air inlet pipe 2 and the exhaust pipe 3 are connected with first one-way valves. The air inlet pipe 2 and the exhaust pipe 3 are controlled to open and close in one direction through two sets of first one-way valves.

[0033] Specifically, both the outer ends of the intake pipe 2 and the exhaust pipe 3 are fitted with sealing gaskets 13. The two sets of sealing gaskets 13 facilitate the sealing connection between the intake pipe 2 and the exhaust pipe 3 and the external pipeline to prevent air leakage. The intake pipe 2 is fitted with a coarse filter plate 14, which pre-intercepts and filters large particulate impurities mixed in the exhaust gas entering the intake pipe 2. The exhaust pipe 3 is fitted with a fine filter plate 15, which intercepts and filters the small particulate impurities remaining in the treated exhaust gas before it is discharged.

[0034] Specifically, a cleaning pipe 16 is connected to the tank cover of the treatment tank 1, and a drain pipe 17 is connected to the bottom of the treatment tank 1. The drain pipe 17 is located above the air distribution plate 55. Both the cleaning pipe 16 and the drain pipe 17 are connected to a second one-way valve. Through the two sets of second one-way valves, the cleaning pipe 16 and the drain pipe 17 are controlled to open and close in one direction. When it is necessary to clean the internal parts of the treatment tank 1, clean water and cleaning agent are added into the treatment tank 1 through the cleaning pipe 16, and the waste liquid generated by cleaning is discharged through the drain pipe 17.

[0035] Example 2, refer to Figures 1 to 7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the inner end of the air inlet pipe 2 is provided with an air distribution assembly for uniformly distributing the exhaust gas of the treatment tank 1. The air distribution assembly includes an air distribution plate 55 that rotates at the bottom of the treatment tank 1, and a four-way valve 51 connected to the inner end of the air inlet pipe 2. The air inlet pipe 2 is electrically opened and closed through the four-way valve 51. The top of the four-way valve 51 is connected to a liquid storage tank 52 to store the adsorbent for use in the exhaust gas adsorption reaction.

[0037] Furthermore, the four-way valve 51 and the liquid storage tank 52 are connected by a threaded connection. The liquid storage tank 52 is threadedly connected to a lid, which facilitates the addition of adsorbent into the liquid storage tank 52. The lid is also equipped with a liquid level sensor to monitor the liquid level of the adsorbent in the liquid storage tank 52 in real time, so as to replenish the adsorbent in a timely manner.

[0038] A quantitative sensor 53 is embedded at the bottom of the four-way valve 51 to quantitatively process the adsorbent entering the four-way valve 51, so as to prevent excessive adsorbent addition and waste, and insufficient adsorbent addition and incomplete adsorption reaction with waste gas. The inner end of the four-way valve 51 is connected to a mixing and pressurizing pipe 54 connected to the air distribution plate 55, which pressurizes the incoming waste gas and the adsorbent it carries to improve the flow of waste gas. The mixing and pressurizing pipe 54 and the treatment tank 1 are sealed through to prevent waste gas leakage due to poor sealing between the mixing and pressurizing pipe 54 and the treatment tank 1.

[0039] Specifically, the air distribution plate 55 is equipped with a pressurization component, which includes a main nozzle 61 connected to the middle of the air distribution plate 55, and a gathering chamber 62 opened in the main nozzle 61. The gathering chamber 62 adopts a double-layer frustum design. Through the main nozzle 61, the waste gas and its entrained adsorbent supplied into the air distribution plate 55 are transported upward from the middle of the air distribution plate 55. Through the gathering chamber 62 with double-layer frustum design, the waste gas and its entrained adsorbent entering the main nozzle 61 are gathered and pressurized, thereby improving the upward transport power and flow of the waste gas and its entrained adsorbent.

[0040] A vertical nozzle 63 is vertically connected to the air distribution plate 55, and an inclined nozzle 64 is inclinedly connected to the air distribution plate 55. Several vertical nozzles 63 and inclined nozzles 64 are distributed in a circumferential manner along the longitudinal axis of the air distribution plate 55. Through several vertical nozzles 63, the waste gas supplied into the air distribution plate 55 and the adsorbent it carries are transported upward in a circumferential direct injection manner.

[0041] Through several oblique nozzles 64, the waste gas and the adsorbent it carries into the air distribution plate 55 are transported upward in a circumferential oblique spray manner, forming a spiral upward conveying state for the subsequent swirling operation of waste gas, avoiding sluggish waste gas flow and insufficient power to fully contact and treat the filter material.

[0042] Each of the several straight nozzles 63 and the angled nozzles 64 is provided with a pressurization chamber 65. Through the pressurization chamber 65, the waste gas and the adsorbent it carries through the several straight nozzles 63 and the angled nozzles 64 are pressurized, and the waste gas and the adsorbent it carries are forced to be strongly transported upward.

[0043] Several straight nozzles 63 and angled nozzles 64 are used to achieve a zoned gas distribution effect on the waste gas and the adsorbent it carries in the gas distribution plate 55. This not only makes the gas distribution more uniform and comprehensive, but also prevents the waste gas from flowing turbulently in the lower space of the treatment tank 1. This facilitates the orderly upward transport of the waste gas and subsequent multi-stage filtration and adsorption work, ensuring that the waste gas and the filter material are in full contact for treatment.

[0044] Specifically, the air distribution plate 55 is also equipped with auxiliary components, including support arms 71 fixed to the air distribution plate 55 in a triangular equidistant shape, and wall scraping strips 72 fixed to the outside of the three support arms 71. The wall scraping strips 72 slide against the inner wall of the treatment tank 1 to scrape and clean the exhaust gas particles attached to the inner wall of the treatment tank 1, thereby reducing the cleaning burden on the treatment tank 1.

[0045] Furthermore, a baffle plate 73 is fixed to the top of the inner side of the support arm 71. The baffle plate 73 plays an auxiliary role in turbulence of the passing exhaust gas. The three sets of baffle plates 73 are provided with breaking holes 74. When the powerfully conveyed exhaust gas passes through the breaking holes 74 on the three sets of baffle plates 73, it forces the impurity particles carried in the exhaust gas to collide with the breaking holes 74. Under the action of the impact force, the large particles of impurities are then crushed into small particles of impurities, which avoids the particles of impurities being too large and causing blockage of the filter material, and is conducive to the subsequent treatment of exhaust gas.

[0046] Furthermore, the baffle 73 has tilted and rotating baffle blades 75. Under the impact force of the exhaust gas flow, the three sets of baffle blades 75 are forced to rotate within the three sets of baffles 73. The tilted and rotating three sets of baffle blades 75 assist in the upward turbulence treatment of the passing exhaust gas, thereby achieving the auxiliary dynamic turbulence effect of the exhaust gas.

[0047] Example 3, referring to Figures 1 to 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] Specifically, the inner cylinder 4 is equipped with a reciprocating assembly and a processing assembly for adsorbing and filtering the exhaust gas in the treatment tank 1. The reciprocating assembly includes a drive motor 81 fixed to the top of the treatment tank 1, and a reciprocating lead screw 82 fixed to the output shaft of the drive motor 81. The reciprocating lead screw 82 is fixed to the three support arms 71 through a connecting seat. The drive motor 81 drives the air distribution plate 55 on the three support arms 71 through the reciprocating lead screw 82 to achieve a swirling effect. The exhaust gas conveyed by the air distribution plate 55 is strongly conveyed upward in a spiral shape to prevent the power from weakening when the exhaust gas is conveyed upward, thus forcing the exhaust gas to remain strong as always.

[0049] The bottom end of the air distribution plate 55 is connected to the rotating end 10, and the top end of the mixing and pressurizing pipe 54 is connected to the connecting end 11. The rotating end 10 and the connecting end 11 rotate and remain in communication. When the air distribution plate 55 is in swirling motion, it forces the rotating end 10 on the air distribution plate 55 to rotate at the connecting end 11 on the mixing and pressurizing pipe 54, without affecting the mixing and pressurizing pipe 54 to deliver exhaust gas into the air distribution plate 55.

[0050] A screw sleeve 83 is threaded onto the reciprocating screw 82, and a frame 84 that slides with the inner sleeve 4 is sleeved on the outer side of the screw sleeve 83. The frame 84 is driven to reciprocate and lift through the screw sleeve 83 on the reciprocating screw 82, providing driving convenience for the subsequent filter material to treat the exhaust gas.

[0051] The processing tank 1 has a ring-shaped sliding cavity 85 that slides with the frame 84. The sliding cavity 85 plays a sliding limit role for the frame 84, improving the stability of the reciprocating lifting and lowering action of the frame 84. The connection end of the frame 84 and the sliding cavity 85 is designed with rounded chamfers to improve the smoothness of the contact between the end face of the frame 84 and the sliding cavity 85.

[0052] Furthermore, a turbulence impeller 12 is fitted on the output shaft of the drive motor 81 to turbulently exhaust the exhaust gas through the exhaust pipe 3. The turbulence impeller 12 adopts a lightweight and streamlined design to reduce the weight and rotational burden of the turbulence impeller 12 and improve the turbulence exhaust efficiency of the turbulence impeller 12 on the treated exhaust gas. Through the turbulence impeller 12, the treated exhaust gas is turbulently discharged through the exhaust pipe 3 to prevent the treated exhaust gas from lingering in the upper space of the treatment tank 1.

[0053] Specifically, the treatment components include activated carbon adsorption plates 91, ultra-nano filter plates 92, and molecular sieve adsorption plates 93, which are embedded in the frame 84 from top to bottom. The frame 84 drives the four sets of activated carbon adsorption plates 91, ultra-nano filter plates 92, and molecular sieve adsorption plates 93 to move back and forth in the treatment tank 1, so as to achieve dynamic adsorption and filtration of particulate impurities in the exhaust gas. It also plays a role in zoning and multi-stage treatment of the exhaust gas, preventing turbulence in the filter material area and ensuring that the exhaust gas fully contacts and is treated by the filter material.

[0054] The activated carbon adsorption plate 91, the ultra-nano filter plate 92, and the molecular sieve adsorption plate 93 are distributed in a circular and equidistant manner along the longitudinal axis of the skeleton 84, which improves the rationality of the distribution of the activated carbon adsorption plate 91, the ultra-nano filter plate 92, and the molecular sieve adsorption plate 93, and comprehensively and effectively performs three-stage filtration and adsorption treatment on the passing waste gas.

[0055] It also includes an interceptor 94 fixed to the top of the inner cavity of the treatment tank 1. The interceptor 94 delays the flow of the dynamically treated exhaust gas, preventing the exhaust gas from flowing too strongly and causing turbulence in the upper space of the treatment tank 1, which is conducive to exhaust work. The interceptor 94 and the inner cylinder 4 are fixed, and fine filter screens 95 are embedded around the interceptor 94. The fine filter screens 95 provide auxiliary filtration for the exhaust gas delayed by the interceptor 94, intercepting the fine impurity particles remaining in the treated exhaust gas, improving the cleanliness of the exhaust gas and making it meet the standards.

[0056] The working principle is as follows: the chemical waste gas to be treated is first coarsely filtered through the coarse filter plate 14, then pressurized by the external pump and supplied into the four-way valve 51 through the air inlet pipe 2. At the same time, the adsorbent pre-added in the liquid storage tank 52 is quantitatively processed by the quantitative sensor 53 and quantitatively combined with the waste gas in the four-way valve 51. The waste gas carrying the quantitative adsorbent is then pressurized through the mixing and pressurizing pipe 54 and reaches the air distribution plate 55.

[0057] The exhaust gas in the air distribution plate 55 is then simultaneously gathered and pressurized by the gathering chamber 62 in the main nozzle 61, and further pressurized by the pressurization chamber 65 in several circumferentially vertical straight nozzles 63 and circumferentially inclined nozzles 64. The gas is then pressurized and transported to the upper space of the treatment tank 1 in both vertical and inclined manner. Under the impact force of the exhaust gas flow, the three sets of turbulence vanes 75 are forced to rotate within the three sets of turbulence plates 73. The three sets of turbulence vanes 75 rotate at an angle to assist in the upward turbulence treatment of the passing exhaust gas. At the same time, when the powerfully transported exhaust gas passes through the breaking holes 74 on the three sets of turbulence plates 73, the impurity particles carried in the exhaust gas are forced to collide with the breaking holes 74. Under the action of the impact force, the large particles of impurity are then crushed to form small particles of impurity.

[0058] At the same time, the control drive motor 81 is turned on and drives the turbulence impeller 12 and the reciprocating screw 82 to rotate synchronously. The reciprocating screw 82 drives the air distribution plate 55 to rotate through the three support arms 71. The rotating end 10 on the air distribution plate 55 rotates at the connecting end 11 on the mixing and pressurizing pipe 54. At the same time, the waste gas and adsorbent in the mixing and pressurizing pipe 54 also pass through the rotating and interconnected connecting end 11 and rotating end 10 in sequence and reach the air distribution plate 55. The rotating air distribution plate 55 then passes through the main nozzle 61, several circumferentially vertical straight nozzles 63 and circumferentially inclined nozzles 64 to further powerfully transport the waste gas in a spiral upward shape in a swirling manner. The three support arms 71 in the rotating state drive the three wall scraping strips 72 to scrape and clean the particulate impurities attached to the inner wall of the treatment tank 1.

[0059] The rotating reciprocating screw 82 drives the frame 84 on the screw sleeve 83 to reciprocate and lift along the sliding cavity 85 inside the inner cylinder 4 and the treatment tank 1. Subsequently, the reciprocating and lifting frame 84 drives the four sets of activated carbon adsorption plates 91, ultra-nano filter plates 92 and molecular sieve adsorption plates 93 to reciprocate and lift, performing multi-stage adsorption filtration on the strongly upward-conveyed waste gas and the impurity particles it carries. During this process, the adsorbent continuously reacts with the particulate impurities in the waste gas.

[0060] After passing through multiple stages of adsorption and filtration, the exhaust gas reaches the interceptor frame 94, where a fine filter 95 intercepts and filters the residual impurities in the exhaust gas. At the same time, the rotating impeller 12 turbulently guides the treated exhaust gas into the exhaust pipe 3, where it is then finely filtered by the fine filter plate 15 before being discharged. When the treatment tank 1 needs to be cleaned regularly, water and cleaning agent are added to the treatment tank 1 through the cleaning pipe 16, and the above actions are repeated. The waste liquid generated in the treatment tank 1 is then discharged through the drain pipe 17.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
