Description

Technical Field

[0001] The utility model relates to the technical field of gasifier filters, in particular to a gasifier black water treatment device. Background Art

[0002] The black water filter of the gasifier is the main filtering equipment for the circulating water of the gasifier. In the past, when filtering the black water of the system, the black water enters the filter screen of the outer shell from the liquid inlet pipe for filtering, and the impurities are filtered by the filter screen. In order to ensure the normal operation of the filter, it is necessary to regularly open the cover and lift out the filter screen for cleaning. However, before lifting the filter screen, the fixing screws need to be removed. However, due to the erosion of the black water on the fixing screws, impurities will enter the gaps of the fixing screws and cause jamming, resulting in inconvenient disassembly of the filter screen. Summary of the Utility Model

[0025] Please refer to Figures 1 - 3 , a gasifier black water treatment device, including a housing 1 and a filter element 2. A liquid inlet pipe 3 and a liquid outlet pipe 4 are arranged on the housing 1. The inlet of the liquid outlet pipe 4 is connected to the bottom of the housing 1. Connecting it to the bottom facilitates the outflow of black water. Control valves 5 are arranged on both the liquid inlet pipe 3 and the liquid outlet pipe 4. A support ring 11 is connected to the inner wall of the housing 1, and the support ring 11 is fixed to the inner wall of the housing 1. A cover 12 is connected to the upper end of the housing 1, and the cover 12 is fixed to the top of the housing 1 through bolts and nuts.

[0026] The filter element 2 includes a filter net 21 and a ring body 22 fixed to the upper end of the filter net 21. The ring body 22 extends outwards, and the height of the ring body 22 is lower than the height of the liquid inlet pipe 3. The upper surface of the ring body 22 is a conical surface, and the conical surface enables the black water falling on the ring body 22 to flow into the filter net 21. The upper surface of the support ring 11 contacts the lower surface of the ring body 22, and the support ring 11 supports the filter element 2. An abutting member 13 that abuts against the ring body 22 is connected to the lower side of the cover 12. The upper end of the abutting member 13 is connected to the lower surface of the cover 12. There are two abutting members 13, and the two abutting members 13 are respectively located on both sides of the liquid inlet pipe 3, so that it cannot block the liquid inlet pipe 3 and also makes the filter element 2 relatively stable after installation.

[0027] A limiting groove 14 corresponding to the abutting member 13 is formed on the inner wall of the housing 1. A guiding groove portion 15 is arranged at the upper end of the limiting groove 14. The guiding groove portion 15 facilitates the insertion of the abutting member 13 into the housing 1. When a part of the abutting member 13 is located inside the limiting groove 14, the through hole on the cover 12 corresponds to the through hole on the housing 1, facilitating the bolt to pass through the through hole, so that the installation of the cover 12 is convenient. A lifting lug 23 is fixed on the inner ring of the ring body 22, and the middle of the lifting lug 23 bends upwards. The lifting lug 23 facilitates the removal of the filter element 2.

[0028] The black water enters the filter screen 21 inside the housing 1 through the liquid inlet pipe 3, and the black water after filtering impurities is discharged from the liquid outlet pipe 4 at the bottom. As the impurities are filtered, the impurities in the filter screen 21 will accumulate at the bottom. When cleaning it, the control valves 5 on the liquid inlet pipe 3 and the liquid outlet pipe 4 can be closed, and the cover 12 is opened to lift out the filter screen through the lifting lugs 23, so as to clean the filter element 2. After cleaning, the filter element 2 is put back. When putting it back, the ring body 22 is placed on the support ring 11. There is no need to consider the clamping and fixing of the ring body 22 and the support ring 11. Then the cover 12 is installed. When installing the cover 12, the abutting member 13 descends along the limiting groove 14 until the cover 12 contacts the housing 1. At this time, the bottom of the abutting member 13 contacts the upper surface of the ring body 22. When installing the cover 12, the abutting member 13 and the support ring 11 prevent the filter element 2 from moving longitudinally and also fix the filter element 2. This setting eliminates the use of fixing screws, realizes the efficient maintenance of the filter element 2, and greatly improves the work efficiency.

[0029] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the said principles, the embodiments of the present invention can have any deformation or modification.
