[0039] like Figure 1 As shown, a synthesis gas purification device includes: a shell 1, an upper partition 2, a lower partition 3, an air inlet pipe 4, a gas-solid separator 5 and a water inlet pipe 6. The upper partition 2 and the lower partition 3 are both fixedly arranged in the shell 1, and are arranged at intervals from top to bottom, so as to divide the inner cavity of the shell 1 into an upper cavity 7, a middle cavity 8 and a lower cavity 9 arranged in sequence from top to bottom. The gas-solid separator 5 is arranged in the middle cavity 8, and divides the middle cavity 8 into an exhaust cavity 10 located above the gas-solid separator 5 and an ash discharge cavity 11 located below the gas-solid separator 5. One end of the air inlet pipe 4 is connected to the gas-solid separator 5, and the other end can be connected to an external synthesis gas source, so that the synthesis gas generated by the external synthesis gas source can enter the gas-solid separator 5 through the air inlet pipe 4. The gas-solid separator 5 separates the synthesis gas entering therein into gas and solid, and discharges the gas and solid into the exhaust cavity 10 and the ash discharge cavity 11 respectively. As shown Figure 2 As shown, a vent hole 12 is provided on the upper partition 2, so that the gas in the exhaust cavity 10 can enter the upper cavity 7 through the vent hole 12, and a water inlet hole 13 is provided on the side wall of the upper cavity 7. One end of the water inlet pipe 6 is connected to the water inlet hole 13, and the other end can be connected to an external water source, so that water in the external water source can enter the upper cavity 7 through the water inlet pipe 6 and wash the gas entering the upper cavity 7. An exhaust hole 14 is provided on the top wall of the upper cavity 7, so that the washed gas can be discharged to the outside of the shell 1 through the exhaust hole 14. The gas-solid separator 5 can be a cyclone separator, but is not limited thereto. By adopting such a technical solution, the synthesis gas purification device can have the functions of gas-solid separation and washing of the synthesis gas. Compared with the prior art method of using a combination of multiple equipment to achieve the purification of the synthesis gas, the utility model can reduce the space occupied by the equipment, achieve the purpose of miniaturized design, reduce the production cost, and at the same time shorten the flow path of the synthesis gas during the purification process, thereby greatly reducing the maintenance cost.

[0040] In actual production, Figure 1 As shown in , it also includes an umbrella type demister 15, which is located in the upper cavity 7 and is arranged on the exhaust hole 14 to reduce the water content of the gas discharged from the exhaust hole 14. Figure 1As shown in FIG, the air inlet pipe 4 is connected to the gas-solid separator 5 through the swirler 16, so that the synthesis gas can be rotated into the gas-solid separator 5, thereby improving the efficiency of gas-solid separation.

[0041] Embodiment 2

[0042] Based on Example 1, Figure 1 As shown, it also includes a drain pipe 17, and an ash discharge hole 18 is provided on the lower partition 3, so that the solids in the ash discharge cavity 11 can enter the lower cavity 9 through the ash discharge hole 18. A drain hole 19 is provided on the upper partition 2, and the drain pipe 17 is vertically arranged in the middle cavity 8, and the top end is connected to the drain hole 19, and the bottom end corresponds to the ash discharge hole 18, so that the water in the upper cavity 7 can be discharged into the lower cavity 9 through the drain pipe 17, so that the solids entering the lower cavity 9 are mixed with the water entering the lower cavity 9 to form a liquid-solid mixture 20. Further, as Figure 1 As shown, the lower chamber 9 also includes a discharge pipe 21, and a discharge hole 22 is provided on the side wall of the lower chamber 9. One end of the discharge pipe 21 is connected to the discharge hole 22, and the other end can be connected to an external target location, so that the liquid-solid mixture 20 formed in the lower chamber 9 can be discharged to the external target location through the discharge pipe 21. The liquid-solid mixture 20 mentioned here is a mixture of dust separated from the synthesis gas and water after washing the synthesis gas. In actual production, it can be as follows Figure 1 As shown in FIG. 1 , a drain hole 23 is provided on the bottom wall of the lower cavity 9 (the lowest position in the vertical direction), and a valve 24 is provided on the drain hole 23. When the housing 1 needs to be cleaned, the valve 24 can be opened to allow all the substances (including water and dust) in the housing 1 to be discharged from the drain hole 23 to avoid them being retained inside the housing 1.

[0043] Specifically, Figure 1 As shown in the figure, the lower baffle 3 is in the shape of a cone that tapers downward, the ash discharge hole 18 is located at the bottom of the cone, and the axis coincides with the axis of the cone, so that the dust in the ash discharge cavity 11 can smoothly enter the lower cavity 9 through the ash discharge hole 18 by gravity. And / or, the upper baffle 2 is in the shape of a cone that tapers downward, the drainage hole 19 is located at the bottom of the cone, and the axis coincides with the axis of the cone, so that the water in the upper cavity 7 can enter the lower cavity 9 through the drainage pipe 19 by gravity.

[0044] As an implementation method, Figure 1As shown, the washing device 25 is also included. The washing device 25 is arranged in the upper cavity 7. The gas entering the upper cavity 7 can enter the washing device 25. The water inlet pipe 6 can transport water into the washing device 25. The gas entering the upper cavity 7 can enter the washing device 25 and be washed by the water entering the washing device 25 before being discharged outside the washing device 25. That is to say, after the gas enters the upper cavity 7, it first enters the washing device 25 for washing, and then is discharged from the washing device 25 into the upper cavity 7, and finally is discharged from the exhaust hole 14 to the outside of the housing 1.

[0045] In actual production, the washing device 25 can be a tower tray, but is not limited thereto, wherein the number of tower trays can be at least two, and at least two tower trays are arranged in sequence and at intervals along the vertical direction. The tower tray is not the invention of the utility model, but a prior art. The utility model only utilizes this prior art and does not intend to improve it, so its structure and working principle are not described in detail here.

[0046] Embodiment 3

[0047] Based on Example 1 or Example 2, Figure 2 , 3 As shown, it also includes a water blocking member 26, which is located in the upper cavity 7 at a position corresponding to the vent hole 12 and is fixedly connected to the upper partition plate 2 to block the water in the upper cavity 7 from entering the exhaust cavity 10 through the vent hole 12. In this way, it can prevent the water in the upper cavity 7 from entering the middle cavity 8 through the vent hole 12 and affecting the operation of the gas-solid separator 5.

[0048] Specifically, Figure 2 As shown, when the upper baffle 2 is in the shape of a cone that tapers downward, the water retaining member 26 includes a shielding portion 27 and a connecting portion 28. On the section passing through the axis of the cone, the shielding portion 27 is parallel to the upper baffle 2, and there is a distance between the two. The higher end of the shielding portion 27 is fixedly connected to the upper baffle 2 through the connecting portion 28, and the lower end is in a free state. On the projection plane perpendicular to the axis of the vent 12, the projection of the vent 12 is within the projection range of the shielding portion 27. At this time, the flow direction of the gas separated by the gas-solid separator 5 is: from the exhaust cavity 10 through the vent 12 into the gap between the shielding portion 27 and the upper baffle 2, and then into the interior of the upper cavity 7 at the opening formed by the free end of the shielding portion 27 and the upper baffle 2. During the specific production, saw teeth or comb teeth are provided at the end of the shielding portion 27 which is in a free state, so that the gas can be evenly dispersed into the upper cavity 7 from the gap between the shielding portion 27 and the upper partition 2, thereby avoiding the generation of large bubbles when the gas enters the upper cavity 7 and contacts with water, thereby affecting the washing effect.

[0049] Furthermore, if Figure 3 As shown, the vent hole 12 includes a first through hole 29, a second through hole 30, ... an Nth through hole 31, wherein N is an integer greater than 1, and the first through hole 29, the second through hole 30, ... the Nth through hole 31 are sequentially arranged in a spaced relationship along the generatrix direction of the cone formed by the upper partition 2. The water blocking component 26 includes a first shielding member 32 corresponding to the first through hole 29, a second shielding member 33 corresponding to the second through hole 30, ... an Nth shielding member 34 corresponding to the Nth through hole 31.

[0050] The number of the first through holes 29 is at least two, and the at least two first through holes 29 are sequentially spaced apart along the circumference of the cone formed by the upper partition 2, and the shape of the first shielding member 32 is a circular ring that matches the cone formed by the upper partition 2;

[0051] The number of the second through holes 30 is at least two, and the at least two second through holes 30 are sequentially spaced apart along the circumference of the cone formed by the upper partition 2, and the shape of the second shielding member 33 is a circular ring that matches the cone formed by the upper partition 2;

[0052] …

[0053] The number of the Nth through holes 31 is at least two, and at least two Nth through holes 31 are arranged in sequence along the circumference of the cone formed by the upper partition 2 . The shape of the Nth shielding member 34 is an annular shape matching the cone formed by the upper partition 2 .

[0054] It should be noted that when the shape of the first shielding member 32 is a circular ring, it means that the shielding portion 27 in the first shielding member 32 is a circular ring, and the connecting portion 28 is located in a circular ring that matches the shielding portion 27. The structural forms of the second shielding member 33,..., and the Nth shielding member 34 are the same as those of the first shielding member 32.

[0055] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
