Abstract
The utility model discloses a decompression device for rosin distillation. The device comprises a vacuum tank and a buffer tank which are communicated through a connecting pipe, wherein an oil inlet is formed in the top of the vacuum tank; an oil outlet is formed in the bottom of the vacuum tank; a viewing window is formed in the side surface of the vacuum tank; a vacuum-pumping pipe, a pressure gauge and a pressure reducing valve are arranged at the top of the buffer tank; an oil drain outlet is formed in the bottom of the buffer tank; a U-shaped high-pressure water pipe of which the opening is downward is arranged; a water-outlet end of the U-shaped high-pressure water pipe is communicated with the vacuum-pumping pipe; and a water-inlet end of the U-shaped high-pressure water pipe is connected with a motor. The device is simple in structure, and ingenious and reasonable in design. By reducing the pressure in a distillation kettle, the distillation temperature and the distillation time are reduced, the quality of a product is ensured, the energy source consumption is reduced, the yield of oil of turpentine is improved, the yield is improved, and profit is well created for an enterprise.
Description
Technical field
The utility model belongs to the industrial technology field, is specifically related to the decompressor that in a kind of rosin process rosin is distilled.
Background technology
Rosin can be processed into rosin and turpentine oil, is widely used in the industries such as papermaking, paint, medicine, printing and dyeing, coating, weaving, process hides.In the process of rosin, distillation process all adopts direct distillation usually, when distillation still lactones liquid temp is 179 ℃ of left and right sides, can steam in the comprehensive fat liquid about 70% turpentine oil, when the fat liquid temp is raised to 195 ℃, steam turpentine oil in the comprehensive fat liquid about 85%, to from fat liquid, steam remaining turpentine oil, just must greatly improve the temperature of distillation, need to consume very many heats, so not only increase entreprise cost, and the rosin color and luster of producing is deepened, the rosin grade reduces, even local generation cracking, and quality can not be guaranteed.
The utility model content
Technical problem to be solved in the utility model is, overcomes the above defective, provides a kind of in the distillation process of rosin processing, can reduce pressure in the distillation still, improve the decompressor of turpentine oil oil yield.
In order to solve the above technical problem, a kind of decompressor for the rosin distillation of the utility model, comprise the vacuum tank and the surge tank that are communicated with by tube connector, the top of described vacuum tank is provided with that oil-in, bottom are provided with oil-out, the side is provided with form, and the top of described surge tank is provided with vacuum-pumping tube, Pressure gauge and pressure-reducing valve, the bottom is provided with oil drain out; One downward opening U-shaped high-pressure water pipe is set, and its water side is connected with motor with described vacuum-pumping tube connection, water inlet end.
As preferably, the water side of high-pressure water pipe described in the utility model is provided with vacuum head, and described vacuum-pumping tube is connected on the vacuum head.
The decompressor of rosin distillation described in the utility model, tube connector is communicated with vacuum tank and surge tank, enter vacuum tank by the turpentine oil recovery tube through oil-in through distillation still water and turpentine oil out, can be observed the height of vacuum tank Nei Shui, oil by being arranged on form on the vacuum tank sidewall, understand water, the reserves of oil in tank with this; The top of described surge tank is provided with vacuum-pumping tube and pressure-reducing valve, the below is provided with oil drain out, the end of vacuum-pumping tube is communicated with the water side of high-pressure water pipe, the water inlet end of high-pressure water pipe is connected with motor, starter motor, High-Pressure Water is rapid flow in downward opening U-shaped high-pressure water pipe, air in the vacuum-pumping tube is taken away, make and form negative pressure in the surge tank, because tube connector is communicated with vacuum tank and surge tank, and be communicated with the turpentine oil recovery tube between vacuum tank and the distillation still, so all form negative pressure in vacuum tank and the distillation still, at this moment, distillation still lactones liquid temp only need reach about 150 ℃, about 70% turpentine oil can be steamed, and when the fat liquid temp is raised to 165 ℃, about 85% turpentine oil can be steamed, reduced vapo(u)rizing temperature, shorten distillation time, the rosin color of production is not deepened, and does not produce cracking, product quality is guaranteed, and greatly reduces energy resource consumption.The utility model is in the process that vacuumizes, under powerful suction, having unavoidably part turpentine oil is drawn out of in vacuum tank, the setting of surge tank, allow the oil vapour that is drawn out of stay in the surge tank, reduce to greatest extent terebinthine loss, when accumulating in turpentine oil in the surge tank and reaching a certain amount of, can emit from the oil drain out of buffering pot bottom.
The beneficial effects of the utility model: the utility model is simple in structure, designs ingeniously, reasonable, by reducing the pressure in the distillation still, reduces vapo(u)rizing temperature, shorten distillation time, guarantee product quality, reduce energy resource consumption, improve terebinthine yield, improve output, for enterprise creates more multiple-effect benefit.
