DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] like Figure 1-4 As shown, the receiving tank includes a separation structure, a gas inlet structure and a cylinder 7. The gas inlet is located between the separation structure and the cylinder 7. The separation structure includes a filter element 18 located in the upper cylinder 17. The gas inlet includes an air inlet pipe 15 and a drainage inner cylinder 16. The drainage inner cylinder 16 is located in the upper cylinder 17. The interior of the drainage inner cylinder 16 is provided with a limit plate 5 parallel to the diameter direction. The air inlet pipe 15 is located on the side of the upper cylinder 17. A reinforcement ring 14 is also connected between the upper cylinder 17 and the head 13 on the upper part of the cylinder 7. The impure airflow enters the drainage inner cylinder 16 through the air inlet pipe 15, and some larger impurity particles fall into the lower cylinder 3 below the cylinder 7, and then fall out from the lower cylinder 3. Some smaller particles are separated from the filter element 18 in the cylinder 7, and finally the impure gas is purified.

[0032] The air inlet pipe 15 passes through the upper cylinder 17, one end of which is located outside the upper cylinder 17, and the upper cylinder 17 is wrapped with an insulation ring I25, and the other end is located inside the drainage inner cylinder 16. The air inlet pipe 15 is connected to the external impurity-containing gas. The air inlet pipe 15 is connected to the external impurity-containing gas, and the impurity-containing gas enters the drainage inner cylinder 16 from the air inlet pipe 15 to form a swirling gas, so that a part of the larger particle impurities are separated from the drainage inner cylinder 16, and then fall from the cylinder 7 into the lower cylinder 3.

[0033] The drainage inner tube 16 is in an I-shape as a whole, the upper part of the drainage inner tube 16 is located below the filter element 18, the middle part of the drainage inner tube 16 is in a straight tube shape, and the lower part of the drainage inner tube 16 is in an outward trumpet shape. The trumpet shape of the lower part of the drainage inner tube 16 is located in the cylinder 7. The shape of the drainage inner tube 16 is convenient for forming a swirling gas, so that the gas-solid separation in the impurity-containing gas is achieved, forming a preliminary separation of the impurity-containing gas, and separating larger particle impurities.

[0034] The cylinder 7 is cylindrical and is wrapped with an insulation ring II12. An ear-type support 9 is also provided on the upper part of the cylinder 7. An electrostatic grounding plate 10 is also provided on the ear-type support 9. A reserved opening is provided on the cylinder 7 above the ear-type support 9. The insulation ring can keep the cylinder 7 warm. The ear-type support 9 is easy to install. When the staff touches the receiving tank, the electrostatic grounding plate 10 can prevent the receiving tank from generating static electricity as a whole.

[0035] The limit plate 5 is located in the straight cylinder in the middle of the drainage inner cylinder 16. The limit plate 5 is provided with a through hole 5-1. The diameter of the through hole 5-1 is much larger than the diameter of the solid in the impurity-containing gas. The through hole of the limit plate 5 is as large as possible as long as the filter element is not allowed to fall. The limit plate 5 is a through-hole plate and will not hinder the upward movement of impurities, thereby preventing the filter element 18 from falling.

[0036] The top and bottom of the cylinder 7 are the head 13 and the lower cylinder 3 respectively. The lower cylinder 3 as a whole presents a cone with a larger top and a smaller bottom. The angle of the cone is 30-50°. The bottom of the lower cylinder 3 is connected to the connecting flange 1 through a discharge pipe 2. The connecting flange 1 is connected to the external impurity solid collection bucket. The head 13 is provided with a safety valve port 23 and a lifting ear 20. The head 13 is wrapped with a head insulation ring 19. The side of the lower cylinder 3 is provided with a thermometer port pipe 4. The lower cylinder 3 is in a downward cone. When impurities fall downward, they can directly fall down along the inner side of the tapered lower cylinder 3. This can prevent the impurities from accumulating in the lower cylinder 3 and falling directly downward.

[0037] The filter element 18 is located on the connecting plate at the top of the upper cylinder 17. An upper head cover 27 is provided on the top of the upper cylinder 17. The upper cylinder 17 and the upper head cover 27 are connected by a flange, a stud 21 and a nut 22. A positioning pin 26 is provided on the stud 21.

A backflush gas storage tank 24 is connected to the gas outlet 6. A pressure difference port 8 is provided on the side of the gas outlet 6. The pressure difference port 8 can ensure that the pressure inside and outside the cylinder is consistent.

[0038] Working principle: connect the impure gas and the air inlet pipe 15, so that the impure gas is located in the drainage inner cylinder 16 in the form of cyclone gas, so that the larger diameter particles and impurities in the cyclone gas are separated and fall from the lower cylinder 3 through the cylinder 7 and are collected, and the remaining gas is separated by the separation core 18 and finally passes through the gas outlet 6 to complete the separation of the impure gas flow.
