Scrubbing Solution refers to the solution from the washing section when the fractionation is extracted, and a solution for washing the impurities or lobes of the lobes is used in the load organic phase. Washing liquid refers to a variety of drawings according to different requirements. E.g:
The strong acid oxidant washing liquid is accumulated with a naval chromium (K2Cr2O7) and concentrated sulfuric acid (H2SO4). K2CR2O7 has strong oxidation capabilities in acidic solutions, and has little eroded to glass instruments. Therefore, this lotion is the most widely used in the laboratory. The formulation concentration is different, from 5 to 12% of the concentrations.
The alkaline lotion is used to wash the instrument with an oil residue, and this wash liquor is used for a long time (more than 24 hours) soaking method, or a dip method. When taking the instrument from the alkali lotion, wear a latex glove to avoid burn the skin. Commonly used alkali washing solutions include sodium carbonate (Na2CO3, pure base), sodium bicarbonate (Na2HCO3, small soda), sodium phosphate (Na3PO4, sodium phosphate), sodium hydrogen phosphate (Na2HPO4). The potassium per alkanganate is used as washing liquid, and the action is slow, suitable for washing the oil.
In order to produce more high-quality products, ensure the production environment of the factory, industrial cleaning is generally applied to the beginning of modern company. The application of photoelectric liquid level sensor in chemical washing liquid level detection is briefly introduced.
In the process of using the washing equipment, the water level is an important factor affecting the washing effect. The high and low of the water level will affect the concentration of the washing liquid. For detergent, the effect of detergent on the washing effect is mainly determined by the determination of the detergent. High water levels, indicating that the amount of water in the automatic industrial elution machine is large, the detergent concentration will decrease, and the detergent will be reduced. The second water level will affect the mechanical force. When the water level is increased, the vertical height of the washing machine is reduced, so that the equipment to the clothing will weaken, affect the removal ability. Therefore, according to the amount of water content in the water volume of the washing equipment, the amount of equipment can not exceed 80% of the equipment drum, so the water level of the device is also limited, and it cannot be too high. It can be seen that the water level is not accurate, which not only affects the washing effect. Reduces the product's work efficiency and utilization. In order to better detect the water level sensor of the washing equipment, it has become the first choice for the company.
Level sensor is a common sensor for measuring liquid level position, which is used in the form of a height of the bit into an electrical signal. The liquid level sensor is the module circuit, has the advantages of acid resistance, moisture-proof, shock resistance, anti-corrosion, and internal control circuits contain constant current feedback circuits and internal protection circuits, which can make the output maximum current does not exceed 28mA, and thus reliably protect the power supply and make it secondary The instrument is not damaged. However, the complexity and polygon of the liquid level detection environment also brings different challenges for the application of the sensor, for example: high viscosity liquid height detection, aburreous wastewater level monitoring, with foam level height measurement, high corrostructure liquid High alarm, etc. The chemical industry is generally corrosive, first solving corrosion, vibration and interference problem, and introduces a British SST industrial-grade photoelectric level sensor / photoelectric level switch-lLC200D324-003 for corrosive liquid level detection.
The LLC industrial grade level sensor is single point detection, TTL compatible digital level signal output. This sensor is suitable for high-power output, which can directly drive incandescent lights, sound alarms, relays, or other situations. An infrared LED light source and the photoelectron detector are well mounted on the sensitive end of the sensing, ensuring that good light coupling in the air. When the inductive end is immersed in the liquid, the infrared light is transmitted from the tapered surface, while the light intensity of the photoelectric tube will be small, resulting in a change in the output level. Diversified output circuits meet different applications.
Industrial-grade photoelectric liquid level sensor / photoelectric level switch LLC200D324-003 cleaning method
Different cleaning fluids are selected depending on the pollutants. Factory is recommended to use Freon and alcohol solvents. It is forbidden to use a chlorine solvent such as trichloroethane and the like to hazard the sensor material.
Industrial-grade photoelectric level sensor / photoelectric level switch LLC200D324-003 is compatible with liquid media
Before using the target liquid, it can be compatible with the PSU or TrogamID material.
