Description

Technical Field

[0001] This utility model relates to the field of natural gas technology, specifically to a high-efficiency gas filtration and purification device. Background Technology

[0002] Natural gas is mainly composed of methane, which is poorly soluble in water. It is a high-quality energy source that is colorless, odorless, non-toxic, has a high calorific value, is stable in combustion, and is clean and environmentally friendly. However, during the extraction process, natural gas often contains solid particulate impurities and trace amounts of liquid. Natural gas containing impurities can cause serious damage to instruments and meters such as compressors, flow meters, and burners during transmission, and can also cause blockages and wear on pipelines. Therefore, it is necessary to filter and purify natural gas.

[0003] Chinese patent application CN201920653456.6 discloses an environmentally friendly natural gas filtration and purification device, including a housing. A cover plate is installed at the top of the housing, and the cover plate is connected to the housing by a first fixing bolt. The inner wall of the housing has clamping plates, and a desiccant placement frame is located between the clamping plates. An inclined plate is located between the upper and lower top walls of the housing, and an electromagnet is mounted on the inclined plate. A second fixing bolt is threaded onto the inclined plate, and a filter plate is mounted on the second fixing bolt. A spring is sleeved on the second fixing bolt. A dust collection hopper is located at the bottom of the housing. The device uses a controller to intermittently energize the electromagnet. When energized, the electromagnet generates magnetism, causing the filter plate to move. When the electromagnet is de-energized, the spring pushes the filter plate to move, intermittently causing the filter plate to shake left and right, facilitating the removal of dust from the filter plate. This avoids filter plate clogging, reduces the frequency of filter plate cleaning, and because intermittent energization is required, it does not consume a large amount of energy, making the device environmentally friendly.

[0004] However, the following drawbacks still exist:

[0005] When cleaning the filter plates, the natural gas is still flowing. The dust that falls off the filter plates will continue to be blown back onto the filter plates by the flow of natural gas, resulting in poor cleaning effect and room for improvement. Utility Model Content

[0006] This invention aims to solve the problems mentioned in the background art by providing a high-efficiency gas filtration and purification device.

[0007] The specific technical solution is as follows:

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0027] The high-efficiency gas filtration and purification device provided in this embodiment, such as Figure 1 - Figure 4 As shown, it includes: a gas filter housing 1, with symmetrically arranged support legs 2 at the bottom of the gas filter housing 1; inspection covers 3 fixedly connected to both sides of the gas filter housing 1; a gas pipe 4 fixedly installed at the center of the surface of the inspection cover 3; installation grooves 5 opened on both sides of the gas filter housing 1; filter plates 6 inserted into the installation grooves 5; an adsorption plate 7 installed inside the gas filter housing 1; a guiding mechanism 8, set on the gas filter housing 1, used to guide the natural gas entering the gas filter housing 1; a cleaning mechanism 10, set inside the gas filter housing 1, used to clean and collect impurities on the filter plates 6; and a replacement mechanism 11, set on the top of the gas filter housing 1, used to install and seal the adsorption plate 7.

[0028] The high-efficiency gas filtration and purification device using the above technical solution is equipped with a guiding mechanism 8. The electric push rod 805 drives the connecting ring 806, the connecting frame 807, and the rotating rod 808 to rotate. The rotation of the rotating rod 808 drives the guide plate 803 to rotate. By changing the direction of the guide plate 803, the natural gas entering the gas filtration chamber 1 is guided, causing the natural gas to change its flow direction. When it is necessary to clean one filter plate 6, the direction of the guide plate 803 is changed, so that the natural gas flows to another set of filter plates 6. The filter plate 6 can be cleaned individually without affecting the natural gas filtration. During cleaning, the dust will fall into the collection box 1005 and be collected, preventing the dust from being blown back onto the filter plate 6 and affecting the filtration effect of the filter plate 6.

[0029] To prevent natural gas leaks, a sealing strip corresponding to the filter plate 6 is fixedly connected to the inner wall of the mounting groove 5. The filter plate 6 is inclined and installed inside the gas filter housing 1. The filter plate 6 can be maintained and replaced by pulling it out of the mounting groove 5.

[0030] In order to guide the natural gas to flow in different directions, the guiding mechanism 8 includes a partition 801 fixedly connected inside the gas filter box 1, a rotating shaft 802 rotatably connected to one side of the partition 801, a guide plate 803 fixedly connected to the surface of the rotating shaft 802, and limit bars 804 symmetrically arranged inside the gas filter box 1.

[0031] To achieve automatic natural gas diversion, a rotating rod 808 is fixedly connected to the top of the rotating shaft 802. A connecting frame 807 is fixedly connected to the rotating rod 808, and a connecting ring 806 is rotatably connected to the surface of the connecting frame 807. An electric push rod 805 is rotatably connected to the top of the gas filter housing 1, and the telescopic end of the electric push rod 805 is fixedly connected to the connecting ring 806. The electric push rod 805 is activated by the switch 9. The telescopic movement of the electric push rod 805 drives the rotating rod 808 to rotate, which in turn drives the guide plate 803 to rotate, thus diverting the natural gas flow.

[0032] To clean the dust on the filter plate 6, the cleaning mechanism 10 includes mounting rods 1001 symmetrically arranged on both sides of the partition 801. A motor 1002 is fixedly mounted on one end of each mounting rod 1001, and a cam 1003 is fixedly connected to the output shaft of the motor 1002. The motor 1002 drives the cam 1003 to rotate, and the rotation of the cam 1003 knocks on the filter plate 6, thus cleaning the dust on the filter plate 6.

[0033] To collect dust, a channel 1004 is provided at the bottom of the gas filter housing 1, and a collection box 1005 corresponding to the channel 1004 is provided at the bottom of the gas filter housing 1. The dust that is cleaned falls into the collection box 1005 through the channel 1004 and is collected, which facilitates subsequent cleaning.

[0034] For the replacement and maintenance of the adsorption plate 7, the replacement mechanism 11 includes a limiting groove 1101 formed at the top of the gas filter housing 1, a sealing groove 1102 formed at the top of the gas filter housing 1, the adsorption plate 7 being inserted into the limiting groove 1101, and a sealing cover 1103 fixedly connected to the top of the gas filter housing 1, with a sealing ring 1104 corresponding to the sealing groove 1102 fixedly connected to the bottom of the sealing cover 1103. The adsorption plate 7 absorbs moisture from the natural gas; by opening the sealing cover 1103 and pulling the adsorption plate 7 out of the limiting groove 1101, the adsorption plate 7 can be replaced.

[0035] In summary, the high-efficiency gas filtration and purification device provided in this embodiment has the following advantages: A guiding mechanism 8 is provided, which drives the connecting ring 806, connecting frame 807, and rotating rod 808 to rotate via an electric push rod 805. The rotation of the rotating rod 808 drives the guide plate 803 to rotate, thereby changing the direction of the natural gas entering the gas filtration chamber 1. When cleaning one filter plate 6 is required, the direction of the guide plate 803 is changed, directing the natural gas to another set of filter plates 6. The filter plates 6 can be cleaned individually without affecting the natural gas filtration. During cleaning, dust falls into the collection box 1005 and is collected, preventing dust from being blown back onto the filter plates 6 and affecting their filtration effect.

[0036] In use, gas pipe 4 is connected to the natural gas pipeline. Natural gas enters the gas filter chamber 1 through gas pipe 4, is filtered by filter plate 6 and adsorption plate 7, and then exits through another gas pipe 4. Dust in the natural gas is filtered by filter plate 6, and moisture is absorbed by adsorption plate 7 before being discharged from the gas filter chamber 1. When it is necessary to clean filter plate 6, the electric push rod 805 is started by switch 9. The extension and retraction of the electric push rod 805 drives the rotating rod 808 to rotate, which in turn drives the guide plate 803 to rotate, thus reversing the flow of natural gas. After the natural gas is reversed, the motor 1002 is started, driving the cam 1003 to rotate and tap the filter plate 6. Dust falls through the channel 1004 into the collection box 1005 and is collected. After cleaning, the electric push rod 805 is moved in the opposite direction, causing the natural gas to flow to the cleaned filter plate 6 to clean the other filter plate 6. This method does not affect the filtration effect of the natural gas and improves the cleaning effect of the filter plate 6, making it convenient to use.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
