Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a tower-type liquid foam removal baffle device used for a vacuum port of a distillation tower. Background Art

[0002] The distillation tower is a chemical equipment made of rare metal titanium and other materials and their alloys. It has the characteristics of high strength, high toughness, high temperature resistance, corrosion resistance, and light specific gravity. Therefore, it is widely used in chemical, petrochemical, metallurgy, light industry, textile, alkali, pharmaceutical, pesticide, electroplating, electronics and other fields. There are many types of tower equipment. The distillation tower is a tower-type gas-liquid contact device for distillation. There are two main types: plate tower and packed tower. The comparison between plate tower and packed tower is a complex issue. Many factors are involved. When selecting, the material properties, operating conditions, performance of the tower equipment, and the manufacture, installation, operation and maintenance of the tower equipment should be considered. The distillation principle of the distillation tower is to partially vaporize the liquid mixture and use the different volatilities of the components therein to achieve separation. The bottom of the tower is liquid and the gas is distilled from the top of the tower.

[0003] However, in the chemical production process, materials often need to be distilled. The production conditions are to heat to high temperature and carry out under high vacuum. When vacuuming, some splashing oil in the material will be taken away with the vacuumed gas. The conventional design is to add a wire mesh demister at the vacuum port, but it has some disadvantages. First, the gas resistance is large, second, it is difficult to install and clean, and third, the cost is high. It needs to be produced by professional manufacturers, which is not conducive to daily use. Therefore, it is urgent to design a tower-type liquid-foam removal baffle device for the vacuum port of the distillation tower to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of the utility model is to provide a tower-type liquid-foam removal baffle device for a vacuum port of a distillation tower, so as to solve the problem raised in the above-mentioned background technology that in the existing chemical production process, materials often need to be distilled, and the production conditions are heated to a high temperature and carried out under a high vacuum degree. When the vacuum is drawn, some splashed oil in the material will be taken away with the vacuumed gas. The conventional design is to add a wire mesh demister at the vacuum port, but it has some disadvantages. First, the gas resistance is large, second, it is difficult to install and clean, and third, the cost is high and it needs to be produced by professional manufacturers, which is not conducive to daily use.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical scheme: a tower-type liquid foam removal baffle device for a vacuum port of a distillation tower, comprising a discharge port, a tank body is arranged on the top of the discharge port, a filling rack is arranged on the inner wall of the tank body, an ear seat is arranged at the center of the side of the discharge port, a feed port is arranged on the left side of the tank body near the top, and a material pressing rack is arranged on the inner top wall of the tank body.

[0006] Preferably, a vacuum port body is fixedly connected to the top of the tank body, and a manhole is provided on the right side of the tank body near the top.

[0007] Preferably, a reboiling gas inlet is arranged on the right side of the tank body near the bottom, and thermometer interfaces are evenly arranged on the sides of the bottom of the tank body.

[0008] Preferably, a tower plate assembly is provided on the inner wall of the top of the tank body.

[0009] Preferably, a blocking plate is provided at the edge of the tower plate assembly, and a pedal is provided on the inner wall of the blocking plate.

[0010] Preferably, exhaust holes are evenly arranged on the surface of the pedal.

[0011] Preferably, a press filter frame is provided at the bottom of the press frame, and a conveying seat is provided on the inner wall of the press frame.

[0012] Preferably, a diffuser cover is provided on the top of the pressing frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The tower-type liquid foam removal baffle device for the vacuum port of the distillation tower can effectively remove liquid foam by means of the arranged discharge port, tank body, vacuum port body, tower plate assembly, plugging plate, pedal and exhaust hole. In the production of biodiesel, during the purification process of crude fatty acid methyl ester, the light component must first be distilled out inside the tank body. The production conditions are heating to above 200°C and high vacuum degree. When vacuuming, some splash oil in the crude fatty acid methyl ester will be brought into the light component. The conventional design is to add a wire mesh removal baffle at the inner top wall position of the tank body. The demister has some disadvantages, one is that the air resistance is large, the second is that it is difficult to install and clean, and the third is that the cost is high. It needs to be produced by a professional manufacturer. Now the tower plate assembly components are added. When vacuuming, the airflow hits the pedal, and the small droplets are collected on the pedal, and then converge to the bottom of the pedal and return to the processed material. The airflow goes up along the pedal and is drawn away through the exhaust hole. It can be produced in its own production workshop, and the tower plate assembly can be purchased directly on the market. It has low cost, short construction period, simple structure, and better effect than that of the demister, which reflects the practicality of the equipment design.

[0015] The tower-type liquid foam removal baffle device for the vacuum port of the distillation tower further improves the overall use effect of the equipment by arranging the press rack, the press filter rack, the conveying seat and the diffuser cover. In daily use, when the crude fatty acid methyl ester is purified to the press rack position inside the tank body, it can be effectively blocked by the press filter rack of the press rack, so that only a part of the substances that need to be separated flows into the conveying seat. At the same time, the substances inside the conveying seat are separated again by the conveying seat, and then dispersed and diffused toward the position of the tower plate assembly at the top of the tank body along the diffuser cover, thereby ensuring that the tower plate assembly of the equipment is more fully in contact with the splashing oil, and then the distillation process is completed, which reflects the comprehensiveness of the equipment design.
