[0025] In this application, unless otherwise clearly specified and limited, the terms in this application should be understood in a broad sense, such as connection can be fixed connection, detachable connection or integration, direct connection or indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of different terms in this utility model can be understood according to specific circumstances, and the scope of the specific meaning should be limited to realizing the functions of this application.

[0026] like Figure 1 , 2 As shown, a coal gas dust removal and demisting device comprises: a shell 1, a blocking member 2, a spoiler tube 3, and a fin tube 4. The blocking member 2 is connected to the shell 1, and the blocking members 2 are arranged in sequence to form a multi-row structure. The blocking members 2 between adjacent rows are staggered, and the blocking member 2 is used for collision during the movement of the coal gas. The spoiler tube 3 is located behind the blocking member 2, and there are multiple spoiler tubes 3. The spoiler tube 3 is used to guide the coal gas to rotate in the spoiler tube 3. The fin tube 4 is located behind the fin tube 4, and there are multiple fin tubes 4 that are arranged in the path of the coal gas movement at intervals.

[0027] In some embodiments of the present application, Figure 1 , 2 As shown, the shell 1 is arranged in a transverse direction, the front end of the shell 1 has an air inlet 101, and the rear end has an air outlet 102, and the gas passes through the shell 1 from the front to the rear.

[0028] In some embodiments of the present application, Figure 1 , 2 As shown, the blocking members 2 form two rows of structures, and each row has a plurality of blocking members 2 arranged at intervals; the meaning of the misalignment is that there is a gap between the two blocking members 2 in the front row, and the blocking member 2 in the rear row is located directly behind the gap. Through this arrangement structure, the coal gas is forced to fully collide with the blocking member 2, causing the airflow direction to change drastically multiple times, thereby improving the dust removal and demisting effect.

[0029] In some embodiments of the present application, Figure 1 , 2 As shown, the blocking member 2 is provided with grooves on the surface facing the coal gas, through which the coal gas impacts, forcing the gas to stop suddenly and change the direction of movement drastically.

[0030] In some embodiments of the present application, Figure 1 , 2 As shown, the blocking member 2 is made of channel steel.

[0031] In some embodiments of the present application, Figure 1 , 2 As shown, the spoiler tube 3 is fixed by the front and rear end plates fixed in the shell 1. The spoiler tube 3 is located between the end plates. The spoiler tube 3 is provided with spiral blades. The spiral blades form a spiral channel in the spoiler tube 3, thereby forcing the coal gas to advance in the spoiler tube 3 in a spiral rotating manner, so that the dust and water vapor therein are separated from the coal gas.

[0032] In some embodiments of the present application, Figure 1 , 2As shown, in the direction from front to back, the spoiler pipe 3 is arranged obliquely downward to facilitate the discharge of the water flow and impurities collected in the spoiler pipe 3.

[0033] In some embodiments of the present application, Figure 1 , 2 As shown, the fin tubes 4 are arranged in sequence to form a multi-row structure, and the fin tubes 4 between adjacent rows are staggered. The meaning of the staggered arrangement is the same as above. The fins on the fin tubes 4 are used to filter the passing gas, and the dust and mist therein are adsorbed and filtered.

[0034] In some embodiments of the present application, Figure 1 As shown, the lower end of the shell 1 has a drain port 103, which can be closed by a valve body or directly connected to a treatment facility such as a sewage pool through a pipeline.

[0035] In some embodiments of the present application, Figure 1 As shown, a manhole 104 is arranged on the side of the shell 1 , and the manhole 104 is closed by a manhole 104 cover. The manhole 104 is located between the spoiler tube 3 and the fin tube 4 , and the operator can enter the shell 1 through the manhole 104 .

[0036] In some embodiments of the present application, Figure 1 As shown, the shell 1 is provided with a backwash port 105, which is used to flush the spoiler tube 3, wherein the backwash port 105 is arranged at the upper end of the shell 1 and is located obliquely above the spoiler tube 3, the backwash port 105 is connected to an external high-pressure water source through a pipeline, and a valve for controlling the on-off of the pipeline is arranged at the backwash port 105.

[0037] During the operation of the coal gas dust removal and demisting device, coal gas is introduced into the shell 1 through the air inlet 101, and the coal gas is processed by the blocking member 2, the spoiler tube 3, and the fin tube 4 in sequence before being discharged through the exhaust port 102. In this process, the dust and mist in the coal gas can be better removed through the principles of airflow impact, airflow rotation, and airflow filtration, thereby discharging pure coal gas.
