Abstract

The embodiment of the present application discloses a drying sludge deodorization system, which relates to the technical field of odor control. The drying sludge silo is externally connected with a first cold air duct, one end of the first cold air duct is connected with the drying sludge silo, and the other end of the first cold air duct is communicated with the atmosphere; A cooling replacement device is arranged in the sludge silo, and the output end of the deodorization replacement fan is connected with an air outlet; the deodorization replacement fan draws out the cooled air in the dried sludge silo and passes through the Said air duct discharge. The embodiments of the present application are suitable for deodorizing dried sludge.

Description

technical field [0001] This application relates to the technical field of odor control. In particular, it relates to a drying sludge deodorization system. Background technique [0002] Sludge treatment technology mainly includes composting, drying, landfilling, incineration and other steps. Among them, sludge drying can effectively reduce the amount of sludge by reducing the moisture content of sludge. It is used as a thermal power plant coupling sludge drying and incineration The pre-processing is widely used at present. [0003] In the prior art, when the dried sludge (with a moisture content of about 40%) enters the power plant boiler for incineration, there is a relatively common problem of odor emission in the transfer station, trestle corridor and other coal transportation systems. [0004] Therefore, it is urgent to invent a system for deodorizing dried sludge. Contents of the invention [0005] In view of this, the embodiment of the present application provides ...
