[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

Detailed implementation mode

[0020] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model.

[0021] As Figure 1 shown, a maze separation device dedicated to biomass gas includes a gas separation main body 1. The gas separation main body 1 includes a separation cylinder 101. The lower end of the separation cylinder 101 extends inwardly and obliquely to form a conical hopper 102. A separation cavity 104 is provided inside the separation cylinder 101. A purification pipe fitting 2 is provided in the middle of the separation cavity 104. A gas outlet 3 is provided on the side of the purification pipe fitting 2. The separation cylinder 101 is provided with a gas inlet 103. The gas inlet 103, the separation cavity 104, the purification pipe fitting 2 and the gas outlet 3 are connected and communicated. The biomass gas enters the inside of the separation cylinder 101 in a tangential manner from the gas inlet 103, and the centrifugal force generated by the rotating gas flow is used to realize gas-solid separation. Then it enters the purification pipe fitting 2 to realize secondary purification and separation, and finally is discharged from the gas outlet 3. The purification efficiency is high, convenient and fast, and will not affect other condensable components in the biomass gas, and does not affect the rear conveying pipeline.

[0022] Specifically, a heating jacket 1011 is provided on the inner wall of the separation cylinder 101. A steam inlet 1012 is provided at the bottom end of one side of the heating jacket 1011, and a steam outlet 1013 is provided at the top end of the other side of the heating jacket 1011. The steam inlet 1012, the heating jacket 1011 and the steam outlet 1013 are connected and communicated. The hot steam enters the heating jacket 1011 from the steam inlet 1012, so that the inside of the heating jacket 1011 is filled with hot steam, and finally is discharged from the steam outlet 1013. This design can transfer the heat of the heating jacket 1011 to the separation cavity 104, so as to ensure that the condensable components in the biomass gas will not condense.

[0023] A water-cooling jacket 1021 is provided on the inner wall of the hopper 102. A cold water inlet 1022 is provided at the bottom end of one side of the water-cooling jacket 1021, and a cold water outlet 1023 is provided at the top end of the other side of the water-cooling jacket 1021. The cold water inlet 1022, the water-cooling jacket 1021, and the cold water outlet 1023 are connected to each other. Cold water enters the water-cooling jacket 1021 from the cold water inlet 1022 and finally discharges from the cold water outlet 1023, thereby cooling the solid particles falling into the hopper 102.

[0024] And as Figure 1 It can be seen that there is a gap between the heating jacket 1011 and the water-cooling jacket 1021. Therefore, the two are independent of each other and do not interfere with each other, so that the hot steam and cold water will not mix with each other.

[0025] A condensate outlet 1014 is provided below the steam outlet 1013. The condensate outlet 1014 is located near the bottom end of the heating jacket 1011. When the high-temperature steam meets cold and releases a large amount of heat, condensation will occur, and the accumulated water droplets will slide down to the condensate outlet 1014 and discharge.

[0026] The bottom end of the purification pipe fitting 2 is provided in the separation cavity 104. The top end of the purification pipe fitting 2 extends outward from the outside of the gas separation main body 1. A cover plate 4 is provided above the purification pipe fitting 2. After the gas separation main body 1 operates for a certain period of time, the purification pipe fitting 2 can be cleaned or replaced by opening the cover plate 4.

[0027] The purification pipe fitting 2 is provided with a hollow interior. A separation material 201 is provided inside the purification pipe fitting 2. The separation material 201 is either a ceramic Raschig ring or porous ceramsite. Both the ceramic Raschig ring and the porous ceramsite have absorption capacity and can further separate the fine particles in the biomass gas.

[0028] An opening and closing valve 1024 is provided at the bottom of the hopper 102 for cleaning the separated solid particles.

[0029] Working principle: The biomass gas enters the separation cavity 104 from the gas inlet 103 along the tangential direction. Therefore, the biomass gas will form a cyclone in the separation cavity 104, so that the solid particles in the biomass gas are thrown towards the inner wall surface of the separation cylinder 101 under the action of centrifugal force for separation. The separated solid particles will fall into the hopper 102 under the action of gravity. During the rapid swirling operation of the purified biomass gas, it rises from the middle of the separation cylinder 101, enters from the bottom end of the purification pipe fitting 2 during the rising process, and contacts the separation material 201, thereby further separating the fine particles in the biomass gas, making the biomass gas further purified, and then being transported to the gas usage place through the gas outlet 3.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
