Description

Technical Field

[0001] The invention relates to the technical field of evaporators, and in particular to a raw material liquid flash evaporation device. Background Art

[0002] A raw liquid flash evaporation device increases the concentration of the solution by rapidly evaporating the solvent in the raw liquid. This is very common in the fields of food industry, chemical industry, pharmaceutical industry, wastewater treatment, etc. In many industrial processes, the solvent is recyclable, and the flash evaporation device can be used to recycle these solvents, reduce waste, and reduce production costs. By controlling the evaporation conditions, different components in the mixture can be separated to achieve separation of substances. By concentrating and separating, impurities in the raw liquid can be removed to improve the purity and quality of the final product. The flash evaporation device usually works at a lower pressure, which means that evaporation can be achieved at a lower temperature, thereby saving energy. By recovering solvents and reducing waste generation, the flash evaporation device helps to reduce the impact on the environment.

[0003] The Chinese patent authorization announcement number is CN113945028B, and its name is a flash burner for an airborne evaporative cycle refrigeration system. The liquid separator ensures that the flash burner performs gas-liquid separation during full-attitude rotation, so that all the refrigerant discharged from the first outlet of the flash burner is gaseous, and all the refrigerant discharged from the second outlet is liquid. The full-attitude liquid suction device ensures that the flash burner can continuously absorb liquid during full-attitude rotation, so that when the aircraft is flying in full-attitude, the flash burner continuously discharges liquid refrigerant from the second outlet. It significantly reduces the energy consumption of the airborne evaporative cycle refrigeration system and improves the reliability and availability of the aircraft's full-attitude evaporative cycle refrigeration system.

[0004] The shortcomings of the above scheme are: although the above scheme can perform gas-liquid separation, it cannot guarantee the stability of the device during use. Due to uneven heating, changes in steam load or unstable control system, pressure fluctuations may be encountered during operation. In addition, it cannot guarantee that the raw materials are heated evenly during use, resulting in local overheating or insufficient heating, and the inside of the device cannot be cleaned. Solid particles or organic matter in the raw material liquid may form deposits inside the device, which will affect the heat transfer efficiency. Technical problems. Summary of the invention

[0019] Advantages of the present invention:

[0020] 1. The limiting mechanism of the present invention is used to fix the position of the evaporation mechanism. Place the two support rings on the heating chamber. By rotating the rotating rod, the rotating nut is driven to rotate. The rotating nut moves closer between the two threaded rods, so that the distance between the two threaded rods becomes smaller, and the distance between the two connecting blocks decreases, that is, the distance between the two support rings decreases, and the position of the evaporation mechanism can be fixed. During the evaporation process, due to thermal expansion, equipment vibration or other external factors, the evaporation mechanism may shift.

[0021] 2. The rotating motor in the distributor of the present invention drives the stirring roller to rotate, so that the raw material liquid is evenly distributed in the distributor. The raw material liquid in the distributor is heated by the heat generated by the heating chamber. The heating chamber evaporates the raw material liquid by heating to generate steam. A condensate water outlet is provided on the heating chamber for discharging condensate water. The steam rises to the condenser and is cooled and condensed into a liquid in the condenser. A liquid outlet is connected to the condenser for collecting the condensed liquid. The condensed liquid and the unevaporated raw material liquid enter the separator, and the liquid and solid substances are separated by the separation plate. Separating the unevaporated raw material liquid helps in recycling and reuse, reducing waste. Effective separation can reduce the impact of solid waste on the environment, reduce manual operation, and improve production efficiency.

[0022] 3. The cleaning mechanism of the present invention is used to clean the residual substances on the separation plate. By rotating the sliding rod, the connecting rod is driven to rotate, and the connecting rod drives the cleaning roller to rotate. The cleaning roller rotates around the rotating shaft. The baffle is used to collect the impurities cleaned from the separation plate. The design of the cleaning mechanism makes the cleaning process automated. The cleaning roller rotates around the rotating shaft, which can effectively scrape and remove the residual substances on the separation plate. The baffle collects the impurities cleaned from the separation plate during the cleaning process, which helps to keep the working environment clean and facilitates subsequent waste treatment.
