Rotational alternative ultrasonic defoaming device

Abstract

The invention relates to a rotational alternative ultrasonic defoaming device which comprises a shell. The rotational alternative ultrasonic defoaming device is characterized in that a feeding hole isformed in the side wall of the lower part of the shell; a liquid outlet is formed in the bottom end of the shell; a vapor outlet is formed in the side wall of the upper part of the shell; a motor isfixedly mounted at the top end of the shell; a first transmission shaft and a second transmission shaft are mounted on the output shaft of the motor through shaft sleeves in a sleeving manner; a baffle plate unit, a first defoamer and a second defoamer are arranged from top to bottom in sequence inside the shell; the baffle plate unit is fixedly mounted on the inner wall of the shell; the first defoamer is mounted on the first transmission shaft in the sleeving manner; and the second defoamer is mounted on the second transmission shaft in the sleeving manner. The rotational alternative ultrasonic defoaming device is scientific and reasonable in design, and due to design of a baffle plate and an ultrasonic wave generator, turbulence of a liquid in the shell can be enhanced, mist foam entrainment can be avoided, liquid drop entrainment in a gas can be effectively eliminated, and the defoaming effect can be improved.

Description

Technical field [0001] The invention belongs to the technical field of evaporation, and relates to an evaporator defoaming device, in particular to a rotating interlaced ultrasonic defoaming device. Background technique [0002] In the chemical, petroleum, pharmaceutical, light industry, metallurgy, machinery, environmental protection and other industries, as an efficient thermal separation technology, evaporation is a widely used unit operation. During the evaporation process, the material liquid passes through the heating chamber to form secondary steam, and then enters the separation chamber for vapor-liquid separation. After separation, most of the material liquid enters the next effect through the material pump for evaporation and concentration. In addition, there is a small amount of material liquid. After the liquid enters the separation chamber, liquid foam or mist-like materials will be produced, reducing its purity. These liquid foam or mist-like materials will general...

Problems solved by technology

[0004] At present, there are some problems in the common wire mesh demisters: using traditional wire mesh filter, the filtering effect is relatively poor, and when there are large droplets in the mist, the wire mesh is easy to be blocked; When the air flow is directly taken away, it forms a secondary entrainment and reduces the defoaming effect; when the airflow velocity is high or the air volume fluctuates greatly, it is easy to cause a sharp change in the airflow, causing severe foaming and reducing the defoaming efficiency; relying on self-weight and passing The air flow rate of the wire mesh, the defoaming effect is unstable when the airflow changes, causing liquid foam to be entrained in the separated gas and affecting the purity of the recovered gas
