Description

Descaling filter and gasification device Technical Field The utility model relates to the technical field of black water filtering devices, in particular to a descaling filter and a gasification device. Background The gasification device is an important device of the synthetic ammonia system, and is responsible for gasifying raw materials at high temperature and high pressure to generate synthetic gas and further synthesize ammonia, so that the stable operation of the gasification device directly affects the continuity, efficiency and cost of the synthetic ammonia system. The gasification device can generate a large amount of grey water in the operation process, the grey water firstly enters a settling tank for solid-liquid separation, solid particles are deposited at the bottom of the settling tank, black water containing a large amount of solid particles is formed at the bottom of the settling tank, and the black water is conveyed to a filter pressing system for further treatment through a black water conveying pump. At present, as industrial wastewater is mixed and burned in a pulping process, the hardness of ash water produced by a gasification device is increased, ash water scale sheets are deposited and attached on the inner wall of a settling tank to form blocks slowly, the block scale sheets are large in size and easily cause the blockage of a black water conveying pump, black water is difficult to smoothly convey to a filter pressing system, the stability of the black water conveying pump is poor, and the operation stability of the gasification device is further influenced. Disclosure of utility model The present utility model aims to solve at least one of the technical problems in the related art to some extent. Therefore, the embodiment of the utility model provides the descaling filter which can remove massive scale flakes with larger volume in black water, prevent the blockage of a black water conveying pump caused by the massive scale flakes, and ensure the stable operation of the black water conveying pump, thereby improving the operation stability of a gasification device.
