Large fermentation tank internal sanitary heat exchanger with baffle function

Abstract

The invention provides a large fermentation tank internal sanitary heat exchanger with a baffle function, and relates to the technical field of fermentation tank heat exchangers. The large fermentation tank internal sanitary heat exchanger comprises a heat exchanger main body, supports and a fermentation tank, wherein the supports are welded on the outer side of the heat exchanger main body, the plurality of sets of supports are arranged, and the heat exchanger main body is welded on the inner wall of the fermentation tank through the supports. According to the large fermentation tank internalsanitary heat exchanger, compared with a traditional tubular heat exchanger, the flattening design can more effectively prevent vortexes from being formed, so that the effect of better replacing baffles is achieved, moreover, the flattening design increases the contact area between a cold medium inside the heat exchanger and a fermentation liquor, the heat exchange efficiency is improved, and inaddition, the large fermentation tank internal sanitary heat exchanger is directly welded to the tank wall, the baffles arranged on the supports through screws are replaced, and the four corners brought by the screws are eliminated, so that cleaning is more convenient, the flattening design reduces dead corners inside the tank, and the cleaning difficulty is further reduced.

Description

technical field [0001] The invention relates to the technical field of fermenter heat exchangers, in particular to a sanitary heat exchanger inside a large fermenter with the function of a baffle Background technique [0002] The baffle is a part that should be equipped with a fermenter with a stirring device. The function of the baffle in the fermenter is to prevent the formation of vortex flow in the center of the liquid surface, enhance turbulence and dissolved oxygen mass transfer; conventional fermenters are usually equipped with 4~ 6 baffles, the width of which is (0.1-0.12)D (D is the diameter of the inner tank of the fermenter). [0003] The heat exchanger is an important device for the heat dissipation of the fermentation tank. During the fermentation process, heat is usually generated. If the heat generated cannot be discharged in time, it will directly affect the effect of the fermentation process. In severe cases, it will lead to fermentation failure and irrepara...

Problems solved by technology

[0003] The heat exchanger is an important device for the heat dissipation of the fermentation tank. During the fermentation process, heat is usually generated. If the heat generated cannot be discharged in time, it will directly affect the effect of the fermentation process. In severe cases, it will lead to fermentation failure and irreparable loss; the current internal heat dissipation method of the fermenter is usually to pass the cold medium through the inner coil tube, inner coil tube and inner tube heat exchanger to cool the fermenter tank and take away a lot of heat

[0004] The original internal heat exchange parts use screws to fix the baffle on the inner wall of the fermentation tank, forming a lot of dead ends for sterilization, which is not conducive to cleaning, easy to cause pollution, and does not meet the design requirements of sanitary equipment. Due to the requirements for cleanliness, At the same time to meet the requirements of heat exchange and full baffle mixing, the present invention designs a large-scale fermenter internal sanitary heat exchanger with baffle function to solve the above problems
