Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection treatment equipment, in particular to a cleaning and flushing device for RTO equipment containing organic silicon waste gas. Background Art

[0002] RTO equipment, namely regenerative thermal oxidizer, often needs to face a variety of complex exhaust gas conditions during operation. Among them, exhaust gas containing silicone is a very special challenge. Since silicone exhaust gas will decompose at high temperature, silicon element will be converted into solid silicon powder after high temperature reaction; this silicon powder will not only gradually accumulate in the chamber of the RTO equipment, but also easily cause a series of problems.

[0003] First, the continuous accumulation of silicon powder will cause the internal space of the RTO equipment to gradually shrink, thus affecting its normal operating efficiency. More seriously, if silicon powder accumulates to a certain extent, it may cause equipment blockage or even equipment failure, resulting in interruption of the production line and causing considerable economic losses to the company.

[0004] In addition, considering the cleaning and maintenance of the equipment, the direct water flushing method is simple but risky because the water flow may damage the insulation cotton and the overall structure of the heat storage chamber during the flushing process, further exacerbating the damage to the equipment and even affecting its service life.

[0005] Therefore, it is particularly important to design a cleaning and flushing device for RTO equipment containing organic silicon waste gas. Utility Model Content

[0011] Preferably, an insert is vertically arranged downward at the bottom of the support plate, and the insert is inserted into the connecting groove to connect the support plate with the flushing frame plate.

[0012] Preferably, a step structure is provided at the contact end between the support plate and the flushing frame plate.

[0013] Preferably, the height of the step structure is 50 cm above the honeycomb ceramic body.

[0014] Preferably, a plurality of load-bearing nodes are arranged on the inner wall of the flushing frame plate, and the load-bearing nodes are butted against the bottom of the layered units.
