Description

Technical Field

[0001] The utility model belongs to the technical field of aerospace furnace quenching chambers, and in particular relates to a spraying ash blocking device for aerospace furnace quenching chambers. Background Art

[0002] Coal gasification refers to the process in which solid fuels such as coal or coke, semi-coke react with a gasifying agent under high temperature, normal pressure or pressurized conditions to be converted into gas products and a small amount of residue. It is an important means of clean and efficient utilization of coal. Large-scale pressurized fluidized bed coal gasification technology is an important way to utilize coal cleanly at present. The quenching chamber, as a key equipment integrated with the gasifier, plays a role in cooling the synthesis gas and has a very important influence on coal gasification. At present, most coal gasification devices such as aerospace furnaces adopt a quenching structure. During the operation of the device, ash and scale are easily accumulated in the pipeline, and will gradually accumulate, eventually causing gas deviation and poor separation of gas, water and ash, resulting in the synthesis gas containing water and ash, causing the quenching chamber to be unable to operate normally and be forced to stop for maintenance, affecting the operating efficiency of the equipment and causing great trouble to production.

[0003] In order to solve the above problems, the existing Chinese patent with publication number CN209481594U discloses a spray ash blocking device for aerospace furnace quenching chamber, and its technical solution includes a quenching chamber, which is located in the shell of the aerospace furnace, and the quenching chamber is symmetrically provided with pipeline mechanisms on both sides, the pipeline mechanism includes an ascending pipe and a descending pipe, and an annular gap is formed between the descending pipe and the ascending pipe, and a spray mechanism is horizontally arranged between the two pipeline mechanisms, and the spray mechanism includes an annular pipe, and a plurality of nozzles are obliquely arranged at the bottom of the annular pipe, and a water inlet pipe is arranged at one end of the annular pipe, and the end of the water inlet pipe away from the annular pipe passes through the quenching chamber and the shell of the aerospace furnace and extends to the outside. The utility model solves the problem that the outer wall of the descending pipe and the annular gap of the ascending pipe in the quenching chamber of the aerospace furnace are very easy to accumulate ash and scale, and the accumulation is increasing, which eventually causes gas deviation and poor separation of gas, water and ash. However, there are also some problems with the device. In the actual use process, there is a lack of auxiliary mechanisms that cooperate with the spray mechanism, and only water film is used to remove the ash, and there is a problem that the ash removal effect is not thorough enough.

[0004] Therefore, in view of the above problems, the present application proposes an aerospace furnace quenching chamber spray ash blocking device that can effectively solve the above problems. Utility Model Content
