Description

Technical Field

[0001] The present invention relates to the field of waste gas treatment, and more specifically, it relates to a waste gas treatment device for environmental protection. Background Art

[0002] When treating solid waste, combustion is usually adopted. After combustion treatment, flue gas containing dust particles and a small amount of harmful gases is generated, and further treatment is required before it can be discharged. In existing related technologies, most of the flue gas is sent to a purification device, but the current purification device has the following problems: 1. Since the flue gas contains a large amount of dust particles, most of them are treated by water spray or the principle of high-voltage static electricity. However, water spray will generate a large amount of waste water, and subsequent treatment is more troublesome. And high-voltage static electricity is easily affected by flammable and explosive gases in the waste gas and cause certain accidents, so the treatment is more inconvenient; 2. Since there is a large amount of heat in the flue gas, there is a lack of effective recovery and utilization in the existing technology, resulting in waste; 3. At present, most only filter dust, and there is a lack of effective treatment for a small amount of harmful gases, which poses a certain safety hazard. Summary of the Invention

[0003] The purpose of the present invention is to provide a waste gas treatment device for environmental protection in order to solve the above problems.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: A waste gas treatment device for environmental protection, including a box body. An arc-shaped plate and two symmetrically distributed inclined plates are installed in the middle and lower part of the box body. An air inlet cavity for waste gas to enter is formed between the two inclined plates and the bottom surface of the box body. An intermediate cavity is formed between the arc-shaped plate and the inclined plates. Each inclined plate is provided with an odd number of through grooves. A regulating mechanism is arranged in the box body for guiding the waste gas to sequentially pass through the through grooves on the same inclined plate. The two sides of the intermediate cavity are communicated with a guiding pipe. A purification cylinder is installed between the two guiding pipes. An air outlet pipe is arranged in the middle of the purification cylinder. An activated carbon purification mechanism is arranged in the purification cylinder.

[0005] After the waste gas enters the air inlet cavity, under the guidance of the regulating mechanism, it sequentially passes through the through grooves on the same inclined plate and enters the intermediate cavity. Thereby, the flow path of the waste gas and the collision of dust particles with the inner wall of the through grooves are increased, the flow velocity of the waste gas is reduced, the aggregation and removal of dust are accelerated, and it is a pure physical treatment, which not only does not require the use of additional resources but also has high safety. At the same time, an activated carbon purification mechanism is added, which can not only further improve the filtering effect of dust particles but also absorb the vast majority of harmful gases in the waste gas, improving the treatment effect of the waste gas.

[0006] Preferably, a cross plate is fixedly connected between the two inclined plates. A first dust outlet is provided at the center of the cross plate, and a first shutter is provided on the first dust outlet for closing it.

[0007] Preferably, each inclined plate is provided with at least three through slots. When there are three through slots, one adjusting mechanism is provided, and for every two additional through slots, one more adjusting mechanism is added.

[0008] By utilizing the quantity cooperation of the through slots and the adjusting mechanism, while guiding the flow path of the waste gas well, the use of other mechanisms can be minimized as much as possible.

[0009] Preferably, the adjusting mechanism includes a bracket installed on the inclined plate and located in the middle cavity. A long shaft is fixedly connected to the bracket, and two reversing plates are rotatably connected to the long shaft. Limit blocks for restricting the rotation of the reversing plates are provided on the inclined plate. A limit rubber strip is also provided on the inclined plate. A limit groove is formed between the limit rubber strip and one of the limit blocks, and the limit groove is used to hold the reversing plate turned to the horizontal state.

[0010] By providing two reversing plates, in the initial state, the two reversing plates are arranged vertically in the same direction, which can play a certain blocking role in the outlets of some through slots, thereby increasing the contact and collision with the waste gas and improving the dust filtration effect. When adjustment is needed, one of the reversing plates can be turned up by ninety degrees and snapped into the limit groove. At this time, a definite gas flow path is formed between adjacent two through slots. Different numbers of reversing plates can be turned according to needs to achieve various extended path situations, thereby improving the waste gas treatment effect. At the same time, in this case, since the waste gas flow will push the reversing plate against the limit block, the occurrence of air leakage is reduced.

[0011] Preferably, short guide plates are installed at the lower edges of the through slots in the odd positions, and long guide plates are installed at the lower edges of the through slots in the even positions and are fixed to the inner wall of the box body. Second dust outlets are provided on the side walls of the box body above each long guide plate, and second shutters for closing them are provided on the second dust outlets.

[0012] By providing short guide plates and long guide plates and using them in combination with the adjusting mechanism, an effective determination of the gas flow path is achieved. At the same time, by providing second dust outlets, it is convenient for the quick cleaning of the accumulated dust.

[0013] Preferably, a windless fan is installed in the through slot.

[0014] By providing a windless fan, part of the wind energy can be converted into kinetic energy to reduce the wind speed, and at the same time, the dust particles in the waste gas can be blocked, thereby greatly removing dust impurities and improving the waste gas treatment effect.

[0015] Preferably, the guiding pipe is composed of a cooling pipe section and a bent pipe section located at the upper end of the cooling pipe section, and a heat exchange pipe is coiled around the outer side of the cooling pipe section.

[0016] By arranging the heat exchange pipe, the waste gas can be cooled, and the effective utilization of heat energy can be realized, promoting the rational use of resources. At the same time, by arranging the bent pipe section above, the flow path of the waste gas can be further increased, making the dust particle removal effect better.

[0017] Preferably, an opening and a sealing door for covering the opening are arranged on the purification cylinder. The activated carbon purification mechanism includes a thick plate and two thin plates. A storage basket for placing activated carbon plates is integrally formed between the thick plate and the thin plates and between the thin plates. A plurality of through holes are arranged on the bottom surface of the storage basket. Semi-circular grooves are arranged on both the thick plate and the thin plates, and the three semi-circular grooves are arranged in a staggered manner.

[0018] Through the above arrangement, the waste gas must pass through two activated carbon plates arranged in a staggered manner before being discharged, which can also extend the treatment path of the waste gas, thereby strengthening the effective treatment of subsequent dust or harmful gases. And by means of one opening, the two activated carbon plates can be replaced, so that the overall area of the opening can be made small, and then the overall length of the sealing ring arranged on the sealing door can be reduced, saving resources and improving the sealing effect.

[0019] Preferably, an adjustment groove and a moving groove communicating with the adjustment groove are arranged on the side surface of the purification cylinder. A pin shaft that is slidably matched with the adjustment groove or the moving groove is fixedly connected to the side surface of the thick plate. When the pin shaft moves to the end of the moving groove, one of the storage baskets corresponds to the position of the opening.

[0020] By arranging the adjustment groove, the positions of the two storage baskets and the opening can be adjusted. That is, in the initial state, the storage basket close to the thick plate corresponds to the position of the opening. At this time, the sealing door can be opened to replace the internal activated carbon plates. When the pin shaft is selected to the other end of the adjustment groove, it can move along the moving groove until it moves to the end of the moving groove. At this time, the storage basket far from the thick plate corresponds to the position of the opening, and the replacement operation can also be carried out. Therefore, the overall area of the opening can be reduced, and the use effect is better.

[0021] Preferably, two groups of the activated carbon purification mechanisms are symmetrically arranged, and the area of the opening is equal to the planar area of the activated carbon plate.

[0022] In summary, the present invention has the following beneficial effects: 1. Through the guidance of the adjustment mechanism, the exhaust gas can sequentially pass through each through - slot on the same inclined plate and enter the intermediate cavity. This increases the exhaust gas flow path and the collision of dust particles with the inner wall of the through - slot, reduces the flow velocity of the exhaust gas, accelerates the aggregation and removal of dust, and is a pure physical treatment method. It neither requires the use of additional resources nor has high safety risks.

[0023] 2. By adding an activated carbon purification mechanism, it can not only further improve the filtering effect of dust particles but also absorb the vast majority of harmful gases in the exhaust gas, thus improving the treatment effect of the exhaust gas.

[0024] 3. By setting heat - exchange tubes, the exhaust gas can be cooled, and the effective utilization of heat energy can be achieved, promoting the rational use of resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Such as Figure 1As shown in the figure, an exhaust gas treatment device for environmental protection includes a box body 1. An arc-shaped plate 4 and two symmetrically distributed inclined plates 2 are installed in the middle and lower parts of the box body 1. A cross plate is fixedly connected between the two inclined plates 2. A first dust outlet 25 is arranged at the center of the cross plate. A first baffle plate 251 for closing it is arranged on the first dust outlet 25. An air inlet cavity 11 for exhaust gas to enter is formed between the two inclined plates 2 and the bottom surface of the box body 1. An intermediate cavity 12 is formed between the arc-shaped plate 4 and the inclined plates 2. Each inclined plate 2 is provided with an odd number of through grooves 21 with at least three in number. A non-powered fan is installed in the through grooves 21, so that a part of the wind energy is converted into kinetic energy to reduce the wind speed, and the dust particles in the exhaust gas can be blocked, and thus the dust impurities can be greatly removed.

[0029] Further, as Figure 1 and Figure 2 shown, a short guide plate 13 which is inclined is installed at the lower edge of the through groove 21 in the odd position, and a long guide plate 14 which is inclined and fixed to the inner wall of the box body 1 is installed at the lower edge of the through groove 21 in the even position. A second dust outlet 15 is arranged on the side wall of the box body 1 above each long guide plate 14, and a second baffle plate 151 for closing it is arranged on the second dust outlet 15.

[0030] It is worth mentioning that, as Figure 1 and Figure 3 shown, an adjusting mechanism for enabling the exhaust gas to sequentially pass through the through grooves 21 on the same inclined plate 2 is arranged in the box body 1. When there are three through grooves 21 on each inclined plate 2, one adjusting mechanism is arranged. For every two additional through grooves 21, one more adjusting mechanism is added. Preferably, there are five through grooves 21, and at this time, two adjusting mechanisms are correspondingly arranged.

[0031] Further, as Figures 1-3 shown, the adjusting mechanism includes a bracket installed on the inclined plate 2 and located in the intermediate cavity 12. A long shaft is fixedly connected to the bracket. Two reversing plates 3 are rotatably connected to the long shaft. A limiting block 23 for restricting the rotation of the reversing plate 3 is arranged on the inclined plate 2. A limiting rubber strip 24 is also arranged on the inclined plate 2. A limiting groove is formed between the limiting rubber strip 24 and one of the limiting blocks 23. The limiting groove is used to hold the reversing plate 3 turned to the horizontal state. When adjustment is needed, one of the reversing plates 3 is turned upwards by ninety degrees and snapped into the limiting groove. At this time, a definite gas flow path is formed between adjacent two through grooves 21, and different numbers of reversing plates 3 can be turned according to needs to realize different extended path conditions and improve the exhaust gas treatment effect.

[0032] It can be understood that, as Figure 2 shown, an arc-shaped part 22 is arranged at the position of the inclined plate 2 corresponding to the adjusting mechanism to cooperate with the rotation of the reversing plate 3, making it more convenient to use.

[0033] Furthermore, as Figure 1 shown, guide pipes are connected to both sides of the middle cavity 12. The guide pipes are composed of a cooling pipe section 51 and a bent pipe section 52 located at the upper end of the cooling pipe section 51. A heat exchange pipe 511 is coiled around the outer side of the cooling pipe section 51 to realize the cooling treatment of the waste gas and effectively recover and utilize the heat energy. A purification cylinder 6 is installed between the two guide pipes. An opening and a sealing door 61 for covering the opening are provided on the purification cylinder 6. An air outlet pipe 62 is arranged in the middle of the purification cylinder 6. An activated carbon purification mechanism 7 is arranged in the purification cylinder 6, and two groups of activated carbon purification mechanisms 7 are symmetrically arranged.

[0034] Furthermore, as Figure 1 、 Figure 4 and Figure 5 shown, the activated carbon purification mechanism 7 includes a thick plate 71 and two thin plates 72. Object placing baskets 73 are integrally formed between the thick plate 71 and the thin plates 72 and between the thin plates 72 and the thin plates 72. The object placing baskets 73 are used for placing activated carbon plates and have a certain positioning effect on the activated carbon plates. The planar area of the activated carbon plate is equal to or slightly smaller than the area of the opening. A plurality of through holes are provided on the bottom surface of the object placing basket 73. Semi-circular grooves 74 are provided on both the thick plate 71 and the thin plates 72. The three semi-circular grooves 74 are arranged in a staggered manner. An adjustment groove 63 and a moving groove 64 communicating with the adjustment groove 63 are provided on the side surface of the purification cylinder 6. A pin shaft 711 slidably matched with the adjustment groove 63 or the moving groove 64 is fixedly connected to the side surface of the thick plate 71. That is, in the initial state, the object placing basket 73 close to the thick plate 71 corresponds to the position of the opening. At this time, the sealing door 61 can be opened to replace the internal activated carbon plates. When the pin shaft 711 is selected to the other end of the adjustment groove 63, it can move along the moving groove 64 until it moves to the end of the moving groove 64. At this time, the object placing basket 73 far from the thick plate 71 corresponds to the position of the opening, and the replacement operation can also be performed. Therefore, the overall fabric of the opening can be reduced, and the use effect is better.

[0035] It is worth noting that elastic limiting bumps are provided on the inner walls of the thick plate 71 and the thin plates 72 on both sides of the object placing basket 73. That is, when a new activated carbon plate needs to be loaded, a force is generated on the activated carbon plate through the elastic limiting bumps to realize the limiting effect on the activated carbon plate.

[0036] Working principle: In use, first adjust the adjusting mechanism as needed, that is, turn the reversing plate 3 upward by ninety degrees according to the need and snap it into the limiting groove to form a definite gas flow path between two adjacent through grooves 21, thereby determining that the waste gas passes through three through grooves 21 or five through grooves 21 in sequence during the flow process. Then, introduce the waste gas into the intake cavity 11. The waste gas passes through each through groove 21 on the same inclined plate 2 in sequence and enters the intermediate cavity 12. During the long path process, due to the mutual collision of dust particles with the inner wall of the through groove 21, the first-stage dust removal effect is achieved. The waste gas that has undergone one-stage treatment in the intermediate cavity 12 continues to flow into the cooling pipe section 51, where the heat exchange pipe 511 is used to cool the waste gas and realize the recovery and utilization of heat energy. Then, the waste gas enters the bent pipe section 52 for the second-stage dust removal effect. After that, the waste gas enters the activated carbon purification mechanism 7 and passes through the activated carbon plates twice along the semi-circular groove 74, which not only further filters the remaining small amount of dust particles but also absorbs the vast majority of harmful gases in the waste gas, improving the treatment effect of the waste gas.

[0037] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
