Abstract

This utility model discloses a waste gas collection device, including a housing. The housing is divided into a dust removal chamber and an absorption chamber. Water and chemical absorption liquid are respectively placed inside the dust removal chamber and the absorption chamber. A fan is fixed to the upper surface of the housing. An air inlet pipe is fixed to the air inlet of the fan, and an air outlet pipe is fixed to the air outlet of the fan. In this utility model, the housing, dust removal chamber, absorption chamber, fan, suction pipe, motor, and exhaust pipe are provided. Water and chemical absorption agents are respectively placed inside the dust removal chamber and the absorption chamber. The waste gas is first drawn into the dust removal chamber by the fan, where water adsorbs particulate impurities in the waste gas. Then, the waste gas enters the absorption chamber through the connecting pipe, where the chemical agents in the absorption chamber absorb harmful substances in the waste gas, making the waste gas treatment more thorough and preventing clogging. In addition, the motor can drive the suction pipe to rotate, increasing the range of waste gas suction and thus improving the waste gas treatment effect.

Description

Technical Field

[0001] This utility model relates to the field of waste gas collection technology, and in particular to a waste gas collection device. Background Technology

[0002] The core objective of industrial waste gas treatment is to effectively treat pollutants emitted during various production processes, mainly including particulate matter, toxic gases, odorous substances, and industrial fumes. This environmental protection work involves various treatment types, such as emission treatment from chemical enterprises, dust control in production areas, removal of volatile organic compounds, neutralization of acid and alkali gases, and elimination of industrial odors, covering the environmental protection needs of many industrial sectors from metal processing to chemical manufacturing.

[0003] A search revealed that patent CN222196309U discloses a waste gas collection and treatment device. This device uses a suction pump to create negative pressure inside the collection box. The inlet pipe and four suction nozzles draw external waste gas into the collection box. When the waste gas passes through the filter plate, the filter plate filters out the dust in the waste gas. Four return springs and a vibration motor can shake off the dust filtered by the filter plate to prevent it from being blocked by dust and ensure the filtration quality of the filter plate.

[0004] However, the above-mentioned device has the following drawbacks: although the device is equipped with a vibrating motor to vibrate the filter plate, the vibration does not thoroughly clean the particles and dust on the filter plate as the device is used, and the treatment effect of the exhaust gas will deteriorate after the filter plate becomes clogged; in addition, it cannot absorb harmful substances in the exhaust gas during the treatment process. Therefore, further improvements are needed, and for this purpose, we propose an exhaust gas collection device. Utility Model Content

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, this utility model includes a housing, a dust removal chamber, an absorption chamber, a fan, a suction pipe, a motor, and an exhaust pipe. Water and chemical absorbent are respectively placed inside the dust removal chamber and the absorption chamber. The fan first draws the exhaust gas into the dust removal chamber, where water adsorbs particulate impurities. The exhaust gas then enters the absorption chamber through a connecting pipe, where chemical absorbent absorbs harmful substances, resulting in more thorough exhaust gas treatment without clogging. In addition, the motor drives the suction pipe to rotate, increasing the range of exhaust gas extraction and thus improving the exhaust gas treatment effect.

[0015] 2. When in use, this utility model is equipped with an exhaust pipe and a filter assembly. The exhaust gas discharged from the absorption chamber will be further filtered by the filter assembly through the exhaust pipe, thereby improving the exhaust gas treatment effect. In addition, the filter assembly can be directly removed from the exhaust pipe, making it convenient to replace the filter assembly. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a waste gas collection device is disclosed, including a housing 1. The housing 1 is divided into a dust removal chamber 101 and an absorption chamber 102. Water and chemical absorption liquid are respectively provided in the dust removal chamber 101 and the absorption chamber 102. A fan 2 is fixed on the upper surface of the housing 1. An air inlet pipe 201 is fixed to the air inlet of the fan 2, and an air outlet pipe 202 is fixed to the air outlet of the fan 2. The air outlet pipe 202 extends to the bottom of the dust removal chamber 101. A sleeve 3 is rotatably connected to the surface of the air inlet pipe 201 through a bearing, and a suction pipe 4 is fixed to the other end of the sleeve 3. A motor 6 for driving the sleeve 3 to rotate is installed on the upper surface of the housing 1. A connecting pipe 9 is fixed to the top of the dust removal chamber 101, and the other end of the connecting pipe 9 extends to the bottom of the absorption chamber 102. An exhaust pipe 10 is fixed to the top of the absorption chamber 102, and a detachable filter assembly 11 is provided inside the exhaust pipe 10.

[0025] Both the dust removal chamber 101 and the absorption chamber 102 are fixed with drain pipes 13 at the bottom, and valves 14 are fixedly installed in the middle of the drain pipes 13.

[0026] In this example, when it is necessary to replace the water or chemical absorbent in the dust removal chamber 101 and the absorption chamber 102, the water or chemical agent can be discharged by opening the valve 14 on the corresponding drain pipe 13.

[0027] Both the dust removal chamber 101 and the absorption chamber 102 are equipped with liquid inlets at the top, and the liquid inlets are equipped with removable sealing caps.

[0028] It is convenient to add water or chemical agents into the dust removal chamber 101 and the absorption chamber 102 through the liquid filling port.

[0029] Multiple suction nozzles 5 are fixed to the side wall of the suction tube 4.

[0030] When the fan 2 is started, the exhaust gas can be drawn from different directions using the multiple suction nozzles 5 on the suction pipe 4.

[0031] The output end of the motor 6 is fixedly connected to the drive gear 7, and the outer wall of the sleeve 3 is fixedly sleeved with the driven gear 8, which meshes with the drive gear 7.

[0032] Through the meshing transmission of the driving gear 7 and the driven gear 8, starting the motor 6 can drive the sleeve 3 to rotate, thereby driving the suction pipe 4 to rotate, so that the suction nozzle 5 continuously changes direction, thereby improving the effect of exhaust gas suction.

[0033] The filter assembly 11 includes a cylinder 111 with open ends. A mesh is fixed at both ends of the cylinder 111, and activated carbon 112 is filled inside the cylinder 111. The outer wall of the cylinder 111 has external threads, and the inner wall of the exhaust pipe 10 has internal threads. The cylinder 111 is rotatably connected to the inside of the exhaust pipe 10 through the threads, and a handle 113 is fixed at one end of the cylinder 111.

[0034] When it is necessary to replace the filter assembly 11 inside the exhaust pipe 10, simply hold the handle 113 and unscrew the cylinder 111 out of the exhaust pipe 10. Then replace it with a new filter assembly 11 and screw it into the exhaust pipe 10.

[0035] An annular plate 12 is fixed to the inner wall of the exhaust pipe 10, and the cylinder 111 fits into the annular plate 12. The annular plate 12 can limit the movement of the filter assembly 11 screwed into the exhaust pipe 10.

[0036] In this embodiment, the chemical agent inside the absorption chamber 102 is either an alkaline absorbent (e.g., NaOH, which can be used to absorb sulfur dioxide or hydrogen chloride) or an acidic absorbent (e.g., H2SO4, which can be used to absorb ammonia). The specific choice can be made flexibly according to the harmful substances contained in the waste gas.

[0037] Working principle: When in use, start the fan 2 and motor 6. Motor 6 drives the suction pipe 4 and multiple suction nozzles 5 to rotate, drawing in exhaust gas from different directions. The exhaust gas enters the dust removal chamber 101 from the exhaust pipe 202. The particulate dust in the exhaust gas is adsorbed by water. Then the exhaust gas enters the absorption chamber 102 from the connecting pipe 9. The harmful substances in the exhaust gas react with the chemical agents in the absorption chamber 102. Finally, the exhaust gas enters the exhaust pipe 10 and is discharged after being filtered by the filter assembly 11.

[0038] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
