Description

Technical Field

[0001] The utility model relates to the technical field of gas filtering, in particular to a gas filtering device for gas power generation. Background Art

[0002] Gas is flammable, combustible, colorless and odorless, and is commonly used for cooking, heating and lighting in homes, businesses and industries. In addition, gas can also refer to other gases, such as natural gas and methane. Gas power generation is a process of generating electricity using natural gas or other gas fuels. Gas power generation has many advantages. First, gas fuel is a relatively clean energy source, and the environmental pollution caused by combustion is less. Secondly, gas power plants can operate flexibly and quickly adjust power generation to adapt to changes in electricity demand. However, gas cannot be used directly to generate electricity. Impurities in gas will affect the calorific value of gas, thereby reducing power generation. Gas needs to be filtered first.

[0003] In the prior art, it is troublesome to replace the filter element of the gas filter device for gas power generation. After the first use and replacement of the filter material, the filter device contains too much air, which reduces the concentration of the gas and is not conducive to subsequent combustion and power generation. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above defects and provide a gas filter device for gas power generation, which can facilitate the replacement of filter materials and discharge the air in the filter device after the first use and replacement of the filter materials, so that the gas maintains a certain concentration, which is beneficial to subsequent combustion and power generation.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a gas filtering device for gas power generation, including a box body, a first air inlet pipe is provided at the upper end of the box body, a first fixing ring, a second fixing ring, and a third fixing ring are movably inserted on the box body in sequence, a filter screen is provided on the first fixing ring, a cleaning device is slidably connected to the filter screen, a drying filter element is provided on the second fixing ring, a filter element is provided on the third fixing ring, a second air inlet pipe is provided on one side of the box body located on the first fixing ring, a first air outlet pipe and a second air outlet pipe are provided on both sides of the box body located below the third fixing ring, one end of the first air outlet pipe is fixedly connected to a collecting box, an adsorption filter screen is provided in the collecting box, and electromagnetic valves are provided on the first air inlet pipe, the second air inlet pipe, the first air outlet pipe, and the second air outlet pipe.

[0006] The advantages of the utility model compared with the prior art are:

[0007] The first fixing ring, the second fixing ring and the third fixing ring which are movably plugged into the box body can be conveniently removed for replacement. The cleaning device on the first fixing ring can prevent blockage. By opening the first air outlet pipe, closing the second air outlet pipe, and then introducing gas, the air is discharged into the collection box, which is beneficial to subsequent combustion and power generation.

[0008] As an improvement, the cleaning device includes a brush slidably connected to the first fixed ring, and an electric push rod is fixedly connected to one side of the box body to drive the brush to slide, so as to clean impurities on the filter screen and prevent clogging.

[0009] As an improvement, sealing rings are provided between the first fixing ring, the second fixing ring, the third fixing ring and the box body to prevent gas from overflowing.

[0010] As an improvement, bolts arranged correspondingly on both sides are provided between the first fixing ring, the second fixing ring, the third fixing ring and the box body to fix the filter material.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 4 As shown, a gas filtering device for gas power generation comprises a casing 1, a first air inlet pipe 2 is arranged at the upper end of the casing 1, a first fixing ring 5, a second fixing ring 6, and a third fixing ring 7 are movably inserted in sequence on the casing 1, a sealing ring 17 is arranged between the first fixing ring 5, the second fixing ring 6, the third fixing ring 7 and the casing 1, bolts 18 are arranged on both sides correspondingly between the first fixing ring 5, the second fixing ring 6, the third fixing ring 7 and the casing 1, a filter screen 8 is arranged on the first fixing ring 5, a brush 15 is slidably connected to the filter screen 8, and an electric push rod 16 for driving the brush 15 to slide is fixedly connected to one side of the casing 1.

[0020] A drying filter element 9 is provided on the second fixing ring 6, a filtering filter element 10 is provided on the third fixing ring 7, a second air inlet pipe 3 is provided on one side of the box body 1 located on the first fixing ring 5, a first air outlet pipe 4 and a second air outlet pipe 11 are provided on both sides of the box body 1 located below the third fixing ring 7, one end of the first air outlet pipe 4 is fixedly connected to a collecting box 12, one side of the collecting box 12 is provided with an exhaust fan 19, an adsorption filter screen 13 is provided in the collecting box 12, a gas concentration sensor 20 is provided in the collecting box 12 between the adsorption filter screen 13 and the first air outlet pipe 4, and an electromagnetic valve 14 is provided on the first air inlet pipe 2, the second air inlet pipe 3, the first air outlet pipe 4 and the second air outlet pipe 11.

[0021] In specific use, when used for the first time, the first fixing ring 5, the second fixing ring 6, and the third fixing ring 7 are inserted into the box body 1, and then fixed by bolts 18, and the first air inlet pipe 2 is opened. At this time, a large amount of air will remain in the box body, and the gas will enter the box body 1. Since the density of the gas is less than that of the air, the gas will push the air downward, and the gas will filter some large impurities through the filter screen 8. The electric push rod 16 on one side of the box body 1 pushes the brush 15 to make the brush 15 move on the surface of the filter screen 8 to prevent clogging, and then the gas passes through the dry filter element 9 to absorb liquid impurities, and then Some tiny impurities and gas impurities are filtered out by the filter element 10. At this time, the gas pushes the air into the first outlet pipe 4 and then into the collection box 12. The exhaust fan is started to discharge the air and a small amount of gas. The adsorption filter 13 on the collection box 12 can adsorb the gas to prevent air pollution. Since the gas is continuously introduced from the first air inlet pipe 2, when the gas concentration sensor 20 in the collection box 12 detects that the gas concentration reaches a certain value, the first outlet pipe 4 is closed. At this time, the gas concentration in the box 1 has reached the concentration required for power generation, and the second outlet pipe 11 is opened.

[0022] When the filter element needs to be replaced, close the first air inlet pipe 2 and the second air outlet pipe 11, open the second air inlet pipe 3 and the first air outlet pipe 4, and then start the exhaust fan on one side of the collection box 12, so as to remove the residual gas in the box body 1 to prevent gas poisoning when replacing the filter material. After the cleaning is completed, close the second air inlet pipe 3, turn the bolt 18, remove the first fixing ring 5, the second fixing ring 6, and the third fixing ring 7, and then replace them. After the replacement is completed, put them back, tighten the bolt 18, and then open the first air inlet pipe 2 and the first air outlet pipe 4, so that the air in the box body 1 after replacement enters the collection box 12. When the gas concentration sensor 20 reaches a certain concentration, close the first air outlet pipe 4 and open the second air outlet pipe 11 to generate gas power.
