Defoaming chemical reaction tank

Abstract

The invention provides a defoaming chemical reaction tank. The reaction tank comprises a tank body, a stirring device, a guide cylinder, a backflow tank and a foam throwing plate, the stirring device comprises a rotating shaft and stirring blades and suction blades arranged on the rotating shaft, the upper end and the lower end of the guide cylinder are open, and the suction blades are located in the guide cylinder. The backflow tank is connected with a tank cover, the guide cylinder is connected with the backflow tank, a backflow opening is formed in the bottom of the backflow tank, and a foam breaking ball is arranged above the backflow opening, so that foam circulation flow is formed in the upper part of the tank body, most of foam is broken in the circulation movement, and the defoaming effect is further enhanced through a foam throwing plate and a foam breaking ball which are arranged in the circulating passage. The mechanical bubble removing mechanism is adopted, so that a good bubble removing effect is achieved, no harmful substance is left, and the problem of bacterial contamination caused by gas backflow is solved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a defoaming chemical reaction tank. Background technique [0002] The chemical reaction tank is a device used in the chemical industry. During the fermentation process of the material placed in the tank, with the continuous growth, reproduction and metabolism of microorganisms, a certain amount of heat will be generated and a large amount of foam will be formed. Causes the risk of bacterial contamination; a large amount of foam also seriously affects the fermentation process, making the fermentation period longer and insufficient fermentation. [0003] Part of the defoaming effect can also be achieved by adding a defoamer to the tank. The commonly used defoamers mainly include polyethers and silicones. There will be residues, and the defoamer is expensive, and a large amount of use will increase production costs. The existing mechanical defoaming methods generally h...
