Description

Technical Field

[0001] The utility model relates to the technical field of coal powder management, in particular to coal powder management equipment used in coalbed methane wells. Background Art

[0002] The shape of the coalbed methane well group arranged on the ground. In order to increase the production of coalbed methane wells and achieve the necessary production scale, coalbed methane should be mined by group wells and arranged into a well network in a certain way. Generally, five-point well networks and rectangular well networks are used, and triangular well networks and diamond well networks can also be used. In the coalbed methane well network, the average drainage area controlled by each well is called the single well control area. If the single well control area is small, the early production of the gas well is high and the cumulative production is low; conversely, the early production of the gas well is low and the cumulative production is high. The determination of the size of the single well control area is related to factors such as the permeability of the coal reservoir and the half-length of the fracture. According to American experience, the generally used single well control area is 0.16 square kilometers, 0.32 square kilometers or 0.65 square kilometers.

[0003] The existing coal powder management usually collects the coal powder and then burns it. In the process of collecting the coal powder, most factories use vacuum equipment to suck the coal powder into the equipment and then collect it. However, there are some shortcomings. For example, in the collection process, the coal powder passes through the vacuum equipment and does not settle after entering the vacuum equipment. It flies around inside the vacuum equipment. Over time, the coal powder will exist in every corner of the vacuum equipment. At the same time, when the vacuum equipment discharges air to reduce the internal air pressure of the equipment, the coal powder hidden in the corner will be discharged, causing environmental damage to the factory. At the same time, when the staff collects the coal powder in the vacuum equipment, some of the coal powder will drift to various places in the factory through the air when the vacuum equipment is turned on, damaging the environment and affecting the health of the staff.
