Description

Technical Field

[0001] The utility model mainly relates to the technical field of methane recovery and processing equipment, in particular to a methane recovery and utilization device. Background Art

[0002] It is well known in the coal production industry that a colorless, odorless, flammable and harmful gas is produced during the coal mining process. This harmful gas contains a large amount of methane. If it is not treated, the methane in it can easily cause an explosion accident. In order to avoid explosion accidents caused by excessive methane concentration, the traditional method is to use ventilation equipment to ventilate the mine, discharge the harmful gas in the mine into the atmosphere, and dilute the harmful gas in the mine to reduce the methane content in the mine air. Although this method can also reduce the methane content in the air in the mine and avoid explosion accidents caused by excessive methane concentration. However, since this method directly discharges the harmful gas containing methane in the mine into the atmosphere, it will not only pollute the atmosphere, but also cause energy waste.

[0003] In the prior art, methane recovery and treatment generally involves filtering, separation and purification, adsorption tanks, condensation, separation, storage and other processing steps. When recovering methane, it is first necessary to filter the dust particles in the methane gas to remove impurities from the methane gas. Existing impurity removal equipment generally intercepts large particles through a filter with a smaller pore size. Once the filter is clogged, it is inconvenient to disassemble and replace, and maintenance is relatively difficult. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model provides a filter barrel and a gas filter assembly. The gas enters the tank body through the air inlet pipe, and the gas is filtered by the filter cotton core on the outer periphery of the filter barrel.

[0021] The gas filter assembly includes a mounting frame 5, and a ring-shaped mounting frame 5 is integrally fixedly mounted on the outer periphery of the filter barrel 2. The top of the mounting frame 5 is open, and a plurality of evenly distributed through grooves 6 are provided around the filter barrel 2. A filter cotton core 7 is inserted between the mounting frame 5 and the filter barrel 2. When this structural design is used, a space for the user to insert the filter cotton core 7 can be formed between the mounting frame 5 and the filter barrel 2. When working, the filter cotton core 7 can filter the methane gas passing through the filter barrel 2 and the through grooves 6, thereby reducing the dust content in the methane gas and improving the cleanliness of the methane gas.

[0022] The mounting frame 5 is a hollow structure. This structural design can facilitate the discharge of methane gas after being filtered by the filter cotton core 7, so that the methane gas can smoothly enter the filter barrel 2.

[0023] A support plate 8 is fixedly mounted on the other side of the tank body 1, and a stepper motor 9 is fixedly mounted on the top surface of the support plate 8. The stepper motor 9 is electrically connected to a power source, and the output shaft of the stepper motor 9 passes through one side of the tank body 1 and is rotationally connected thereto. The output shaft of the stepper motor 9 is rotationally connected to the tank body 1 through a sealed bearing, and a first bevel gear 10 is fixedly mounted on the output end of the stepper motor 9, and a second bevel gear 11 meshing with the first bevel gear 10 is fixedly mounted on the outer periphery of the filter barrel 2. When this structural design is in use, the first bevel gear 10 connected thereto is driven to rotate by the output shaft of the stepper motor 9, and the first bevel gear 10 drives the filter barrel 2 to rotate through the second bevel gear 11 meshing therewith. Through the rotation of the filter barrel 2, the methane gas inside the filter barrel 2 can be more evenly distributed inside it, so that the methane gas can be more evenly discharged in different through slots 6, thereby improving the utilization rate of the filter cotton core 7.

[0025] The top surface of the tank body 1 is provided with an inspection port 14, and the inspection port 14 is internally threaded and equipped with a sealing cover 15. This structural design makes it easy for the user to open the inspection port 14 to replace the filter cotton core 7, so that the user can inspect the device.

[0026] Working principle:

[0027] When in use, methane gas enters the tank body 1 through the air inlet pipe 3, and the methane gas passing through the filter barrel 2 and the through groove 6 is filtered by the filter cotton core 7, and the dust particles in the methane gas are intercepted on the filter cotton core 7, so as to achieve preliminary filtration of the methane gas. The filtered methane gas enters the tank body 1 through the filter barrel 2, and the first bevel gear 10 connected thereto is driven to rotate by the output shaft of the stepper motor 9. The first bevel gear 10 drives the filter barrel 2 to rotate through the second bevel gear 11 meshing therewith. Through the rotation of the filter barrel 2, the methane gas inside the filter barrel 2 can be more evenly distributed therein, so that the methane gas can be more evenly discharged in different through grooves 6, and finally discharged through the exhaust pipe 4. When the filter cotton core 7 needs to be inspected or replaced, the user can open the sealing cover 15 and replace or inspect the filter cotton core 7 through the inspection port 14, thereby improving the practicality of the device.
