Molecular distillation equipment
Molecular distillation is a special liquid-liquid separation technology. It is different from the traditional distillation that relies on the principle of boiling point difference separation, but is related to the molecular weight of the mixture to be distilled. It can achieve operations far away from the boiling point. The greater the difference in molecular weight, the greater the difference in molecular free path, and the purer the distillate. The molecular free path here (using λ It refers to the distance between two adjacent collisions of a molecule.
The materials entering the rotary film evaporator first enter the rotary distribution disk, and are evenly distributed to the vertical inner surface of the evaporator from the distribution disk. While the materials fall by gravity, the rotating film scraper forces a uniform film on the inner surface (the film thickness is related to the form, speed and other parameters of the film scraper), and makes the materials in front of the film scraper form a bow wave.
The separation of two-component mixture is the simplest distillation operation. Typical distillation equipment is continuous distillation equipment, including distillation tower, reboiler, condenser, etc. The two-phase contact of the steam and liquid supplied by the distilling tower is used for interphase mass transfer. The condenser at the tower top partially condenses the steam, and part of the condensate returns to the tower bottom as the reflux, while the rest of the distillate is the product at the tower top.
Volatile organic compounds (VOCs) refer to organic compounds with high vapor pressure and high volatility at room temperature and normal pressure. It can produce PM2.5, ozone and other secondary pollutants through chemical reaction in the environment, and some kinds of volatile organic compounds are carcinogens with toxicity.
The oil-water separator is applicable to the oily wastewater treatment of various kinds of engine oil, diesel oil, gasoline, lubricating oil, animal and vegetable oil, some heavy oil, etc. without surfactant, as well as the cooling lubricating liquid and steel rolling water produced in the process of mechanical manufacturing and processing. For the two-phase separation of aromatic medicine gas condensate, the separation of organic solvent and water in the hydrocondensation gas condensate in rubber production is also an efficient and low energy consumption treatment method.
Single stage 0.2 ㎡ test equipment
According to the classification method, it can be divided into metal material testing equipment, non-metal material testing equipment, dynamic balance testing machine, vibration table, non-destructive flaw detector, etc. The loading method, structural characteristics, force measuring principle and application scope of material test equipment are different.
2 ㎡ five level pilot test device
The testing machine shall be installed in a clean, dry room without vibration and the room temperature can be controlled at (10~35) ℃. The room shall have enough space to ensure that there is more than 70cm space around the testing machine for testing and daily maintenance.
0.1 ㎡ two-stage molecular distillation test device
The perpendicularity of the column on the main body of the testing machine shall be corrected in two mutually perpendicular directions using a frame level or a plumb bob in the attachment, and adjusted by inserting a small iron sheet at the bottom of the main body. Install the anchor screws, if equipped with spring washers. Cement mortar with high strength shall be used to cement the anchor bolt holes at all places, and the gaps between the testing machine and the ground shall be filled. After watering and curing for more than one week, the screws shall be fastened.
0.1 ㎡ single-stage molecular distillation experimental device
Remove the binding materials of each part, and clean the inside of the oil pipe with clean kerosene, especially the thread of the connection port of each oil pipe.
0.1 ㎡ single-stage molecular distillation experimental device
The power supply voltage of the testing machine is three-phase 380V, and the electrical connection between the main body and the hydraulic control box is plug connection. Before power on, open the iron door of the hydraulic control box, check whether all wires fall off, whether the fuse is loose, and clean the dust and debris in the electrical box. After confirming that the equipment has been connected to the power supply line, press the "Power" button on the console panel of the hydraulic control box, and the indicator will light up to show that the information retrieval has been started. Turn on the oil pump and check whether the running direction of the oil pump is consistent with the direction indicated by the arrow. If it is contrary, change any two connected positions, then click the lifting button of the jaw seat, take out the wooden block on the platform, unscrew the oil delivery valve to lift the piston, and check whether the piston travel limit switch works by referring to the ruler on the main column.
0.1 ㎡ single-stage molecular distillation experimental device
It is used to measure the impact resistance of metal materials under dynamic load, so as to judge the properties of materials under dynamic load.
The falling film evaporator carries out evaporation and concentration under the condition of air flow (vacuum) guidance, with high evaporation capacity, low energy consumption, low operating cost, and can largely maintain the original color, fragrance, taste and useful ingredients of materials.
