Device for removing volatile odor from sludge protein solution

Abstract

The invention provides a device for removing volatile odor from a sludge protein solution. The device for removing the volatile odor from the sludge protein solution comprises an evaporating device, a rectifying device and a odorant liquid receiving device, wherein the evaporating device comprises a temperature controller, a tower kettle and a heater on the outer side of the tower kettle; a thermoresistor thermometer is arranged inside the tower kettle; the thermoresistor thermometer interacts with the temperature controller; the heater is connected with a heat carrier pipe; a pneumatic actuator is arranged on the heat carrier pipe; the pneumatic actuator is connected with the temperature controller; a rectifying interface is further formed in the tower kettle; the rectifying interface is connected with the rectifying device; the rectifying device is connected with the odorant liquid receiving device. The device for removing the volatile odor from the sludge protein solution, provided by the invention, does not destroy sludge protein and reduce the purity thereof while sludge protein deodorization is achieved.

Description

technical field [0001] The invention belongs to the technical field of deodorization, and relates to a device for removing volatile odor from sludge protein liquid. Background technique [0002] In recent years, with the increase of sludge production year by year, the resource treatment of sludge has attracted widespread attention. Among many sludge resource technologies, the extraction technology of sludge protein is relatively mature, but the general application of its products is severely limited due to the foul smell of sludge protein. There are three reasons for the analysis of sludge protein stench: First, as a by-product of sewage treatment plants, sludge contains a large number of microorganisms (such as bacteria, fungi, actinomycetes, etc.), protozoa, metazoans, etc., and emits a strong odor. Second, the sludge protein solution is often obtained by hot alkali hydrolysis. During the hydrolysis process, firstly, the sludge flocs are broken, and the intracellular subs...

AI Technical Summary

Problems solved by technology

Chemical deodorization has a certain effect, but at the same time, the sludge protein will be more or less destroyed. At the same time, the follow-up separation procedure is relatively cumbersome, and the protein purity is affected, which in turn restricts the promotion of downstream sludge protein products.
