Steam jet heating, which comprises a steam jet installed on a transfer pipe and injects steam directly into the organic slurry, is a heating method in which steam is injected directly into the organic slurry, causing contamination to be amplified. At the same time, a large amount of water and energy is wasted.

The defects of the three heating heat exchangers are very obvious, firstly, the equipment generally has high failure rate, is difficult to maintain and cannot be cleaned after scaling, and the occupied field space is large and some heat exchangers exceed hundreds of square meters due to large heat exchange area. And secondly, resources are wasted, steam is injected into the organic slurry, pollution is expanded, and heat brought by hot slurry water cannot be recycled in the organic slurry. And thirdly, the requirement on energy transmission in the heating process is high, and the loss of a transmission pressure head is large due to the large heating area and the large number of return bends. Fourthly, the maintenance is difficult, the internal structure is closed in the maintenance process, and particularly, the winding on the constructional column of the spiral plate type heat exchanger needs to be cleaned for a long time.

Therefore, it is necessary to develop a heat exchanger for heating slurry of kitchen waste to overcome the above-mentioned disadvantages.
