Rotary Vane Vacuum Pump for Large Oil Plant
The application of rotary vane vacuum pump in large oil plants is mainly reflected in the practical application of leaching negative pressure evaporation process in large oil plants.
The use of vacuum pumps is very extensive today, and it is even more popular in metallurgy, chemical industry, food, electronic coating and other industries.
We all know of water ring vacuum pumps, reciprocating pumps, rotary piston vacuum pumps, rotary vane vacuum pumps, roots vacuum pumps and diffusion pumps. Today, with the continuous development of various industries, the demand for these pumps is still increasing.
The gas discharged from the evaporative condenser is inhaled by the rotary vane vacuum pump, and the gas-liquid mixture discharged from the evaporative condenser enters the separator along the tangential direction, and is separated in the separator.
The gas discharged from the separator enters the tail gas condenser to maximize the recovery of the solvent contained in the gas. The liquid discharged from the separator is a mixture of solvent and water, which is condensed by the condenser and used as the suction liquid of the rotary vane vacuum pump for recycling.
One point that can be obtained from the application of rotary vane vacuum pumps in large oil plants is that the vacuum degree of the system is related to the condensate temperature of the evaporative condenser. The higher the vacuum degree, the lower the dew point of the solvent, that is, the lower the temperature of the solvent vapor condensate produced by evaporation, which means that the temperature of the cooling water is required to be lower.
Rotary vane vacuum pumps are widely used in coal, oil, natural gas, food packaging, drying, refrigeration, scientific research, medical treatment, electronics, chemical, pharmaceutical and other fields.
At present, in the evaporation section of the grease leaching workshop, the negative pressure evaporation process is widely used because it can not only reduce solvent consumption, steam consumption and refining consumption, but also ensure product quality. In the design of the negative pressure evaporation process of leaching mixed oil, many manufacturers have used rotary vane vacuum pump to evacuate, and have made many attempts in this field and achieved fruitful results.
It has been found from practice that it is completely feasible to apply the rotary vane vacuum pump vacuuming process to the leaching negative pressure evaporation process in large oil plants, and it can reduce the operating cost compared with the conventional full steam vacuuming process under the premise of achieving the same vacuuming effect. The energy saving effect is obvious, and there are also good benefits in environmental protection.
The application of rotary vane vacuum pump in large oil plants is the key to oil production. Its energy consumption and dissolution consumption will directly affect the production cost of oil processing enterprises.
