Description

Technical Field

[0001] The utility model belongs to the technical field of coal gasification ash water treatment, and particularly relates to a coal gasification ash water filtering device. Background Technique

[0002] At present, in most fields such as hydrogen production, synthetic ammonia, MTO, MTP and SNG, the pressurized entrained flow coal gasification technology, which is relatively efficient and environmentally friendly, is adopted at the source. However, whether it is water coal slurry gasification or pulverized coal gasification, the solid content in the generated ash water is relatively low, about 1.0 - 3.0 wt%, and the particle size is small.

[0003] At present, in the process of coal gasification production, the treatment of ash water is an important link to ensure the continuity of production and environmental protection compliance. Traditional filtering devices usually use fixed filter screens for filtration. However, over time, a large amount of large particle impurities will accumulate on the filter screens, resulting in a significant decline in filtration efficiency and even affecting the normal operation of the entire production line. In order to maintain the filtration effect, it is necessary to stop the machine regularly to replace the filter screens, and the existing filter screen replacement methods are often inefficient and cumbersome, increasing production costs and labor burdens. Therefore, a coal gasification ash water filtering device is needed to solve the above technical problems. Content of the Utility Model

They are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it should not be construed as a limitation of the present utility model. In the description of the present utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0023] Please refer to Figures 1 to 5As shown in the figure, an embodiment of the present utility model provides a gasification ash water filtration device, which specifically includes a device main body 100. The device main body 100 includes a filter cylinder 110, and a filter screen assembly 111 is arranged inside the filter cylinder 110. The device main body 100 also includes a filter screen quick replacement mechanism. The filter screen quick replacement mechanism aims to achieve the quick replacement of the filter screen assembly, reduce the downtime, and improve the production efficiency. The filter screen quick replacement mechanism includes an insertion installation groove, a sliding assembly, a filter screen installation cylinder 112, a U-shaped limiting plate 115, and a limiting knob 116. The insertion installation groove is opened on the front of the filter cylinder 110. The filter screen installation cylinder 112 carries the filter screen assembly 111 and is inserted into the filter cylinder 110 through the insertion installation groove. The sliding assembly includes a sliding groove 113 and a sliding block 114. The sliding groove 113 is opened on both sides of the filter cylinder 110. The sliding block 114 is slidably installed inside the sliding groove 113. The sliding block 114 is fixedly connected to the U-shaped limiting plate 115. The U-shaped limiting plate 115 cooperates with the sliding assembly to lock and release the filter screen installation cylinder 112 through sliding operation. The limiting knob 116 is used to finally lock the U-shaped limiting plate 115 to ensure the safety and stability of the replacement process.

[0024] Please refer to Figures 1 to 5 As shown in the figure, the filter screen assembly 111 specifically includes a coarse filter screen 117, a fine filter screen 118, a precision filter screen 119, and a deepening filter screen 120 from top to bottom, which are respectively used to effectively remove large particles, small particles, micro particles, heavy metal ions, organic matters, and microorganisms, ensuring that the quality of the treated ash water meets the environmental protection and production requirements. Specifically, in this embodiment, the large particles mainly refer to impurity particles with a particle size ≥ 0.25 mm, the small particles mainly refer to impurity particles with a particle size between 0.09 mm and 0.25 mm, the micro particles mainly refer to impurity particles with a particle size less than 0.09 mm, and the deepening filter screen 120 is an activated carbon filter screen or a microporous ceramic filter screen to further enhance the adsorption and filtration capacity for harmful substances.

[0025] Please refer to Figures 1 to 5 As shown in the figure, a sealing step is provided at the connection between the filter screen installation cylinder 112 and the insertion installation groove. The sealing step uses multiple high-performance sealing rubber rings to ensure no leakage during the filter screen replacement and operation process, and to ensure the safety of the production environment. An observation window 121 is provided on the front of the filter screen installation cylinder 112, which is convenient for operators to directly monitor the clogging situation and usage status of the filter screen assembly 111, arrange replacement in a timely manner, and avoid affecting the production process. A pull handle 123 is fixedly installed on the front of the U-shaped limiting plate 115. The pull handle 123 conforms to the ergonomic design, which is convenient for operating the U-shaped limiting plate 115. A magnet 122 that attracts each other is arranged between the filter screen installation cylinder 112 and the filter cylinder 110 to achieve preliminary positioning and fixation, reduce the installation error, and speed up the replacement process.

[0026] The specific working principle of the present utility model is as follows: In the initial state, the filter screen installation cylinder 112 carries the filter screen assembly 111 and is inserted into the interior of the filter cylinder 110 through the insertion installation groove. At this time, the U-shaped limit plate 115 is located in the middle of the filter screen installation cylinder 112 through the cooperation of the sliding block 114 and the sliding groove 113, playing a role in limiting the filter screen installation cylinder 112. When it is necessary to replace the filter screen assembly 111, first, the limit of the U-shaped limit plate 115 is released by rotating the limit knob 116, and then the U-shaped limit plate 115 is slid through the sliding assembly, so that the U-shaped limit plate 115 moves away from the locking position of the filter screen installation cylinder 112 to unlock the filter screen installation cylinder 112. With the unlocking of the U-shaped limit plate 115, the filter screen installation cylinder 112 is no longer subjected to the lateral locking force. At this time, it can be easily taken out from the filter cylinder 110, the old filter screen assembly 111 is taken out from the filter screen installation cylinder 112, and a new filter screen assembly is replaced. The filter screen installation cylinder 112 equipped with the new filter screen assembly is re-inserted into the insertion installation groove of the filter cylinder 110. Subsequently, the U-shaped limit plate 115 is slid along the sliding groove 113 until it is located in the middle of the filter screen installation cylinder 112. Finally, by rotating the limit knob 116, the U-shaped limit plate 115 is further locked in the fixed position to prevent it from loosening accidentally during the operation of the equipment.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] The above has described a specific embodiment of the present utility model in detail, but the content described is only the preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
