Stainless steel wire woven filter screen is often used, 30-40 hole/cm filter screen is used for crude oil filtration, and 140-180 hole/cm filter screen is used for decolorization oil filtration. production Microwave liquid sterilization The selection of filter medium will affect the clarification of filtered oil and fat, and whether the cake unloading is smooth. The filter media used in the grease industry are mostly woven media, Microwave liquid sterilization programme Common cotton fabrics such as canvas, twill and ordinary white muslin with 20 yarns and 5-8 strands.
The simple answer is yes, even more organisms. The research shows that 254nm ultraviolet light is effective for all food borne pathogens, natural microbiota, mold and yeast. Microwave liquid sterilization programme Because the size and shape of microorganisms will affect their absorption of ultraviolet light, the time required to kill each species is also different. How does UV sterilize? production Microwave liquid sterilization The working principle of ultraviolet sterilizer, also known as ultraviolet disinfection or ultraviolet germicidal radiation (UVGI), is to destroy some chemical bonds, disrupt the structure of DNA, RNA and protein, resulting in the inability of microorganisms to reproduce. When a microorganism cannot reproduce, it is considered dead because it cannot reproduce in the host body and is no longer infectious.
RCO organic waste gas catalytic combustion purification equipment can effectively purify the environment, pollution, improve labor operating conditions, ensure the health of workers, and the heat emitted can be recycled to reduce production costs. RCO organic waste gas catalytic combustion equipment has perfect system design, complete auxiliary equipment, high purification efficiency and high automation. RCO organic waste gas catalytic combustion equipment RCO organic waste gas catalytic combustion purification device is designed based on two basic principles of adsorption and catalytic combustion, namely adsorption concentration catalytic combustion method. The dedusting equipment adopts the working mode of single bed adsorption purification of organic waste gas and catalytic combustion device regeneration and activation of activated carbon. Firstly, the organic waste gas with low concentration is adsorbed by activated carbon, and the adsorption operation is stopped when it is almost saturated, then the organic matter is desorbed from the activated carbon by hot gas flow to regenerate the activated carbon; The desorbed organic matter has been concentrated (the concentration is dozens of times higher than the original) and sent to the catalytic combustion chamber for catalytic conversion into CO2 and H2O for emission; When the concentration of organic waste gas reaches above 2000ppm, the organic waste gas can maintain spontaneous combustion in the catalytic bed without external heating. Some of the burned tail gas is discharged into the atmosphere, and most of it is sent to the adsorption bed for desorption and regeneration of activated carbon. In this way, the heat energy required for combustion and desorption can be met to save energy. The regenerated activated carbon can be used for the next adsorption.? RCO organic waste gas catalytic combustion equipment uses catalytic combustion method to convert toxic and harmful organic gas into non-toxic gas.? The main structure of RCO organic waste gas catalytic combustion equipment is composed of three major parts: purification device host, induced draft fan and control system. The catalytic combustion purification device includes: dedusting flame arrester, heat exchanger, preheater and catalytic combustion chamber. The organic waste gas enters the preprocessor from the air inlet at the upper part of the equipment, passes through the coarse filter element composed of multi-layer stainless steel wire mesh to remove dust and other particles in the waste gas, and enters the combined adsorption bed from the main channel at the lower part of the device (two rows in parallel with six grids). Each adsorption bed is equipped with a set of pneumatic switch valve, which can change the adsorption bed into adsorption/desorption state. The longitudinal section of the adsorption bed from bottom to top is respectively the inlet manifold, adsorption chamber, air purification chamber and outlet manifold. The adsorption chamber and the air purification chamber are separated by a flower plate, under which a number of adsorption cylinders are hoisted. The waste gas entering the adsorption chamber passes through the adsorption layer through the outer wall of the adsorption cylinder, VOCs are adsorbed by a large number of microporous surfaces of the adsorbent, and the waste gas is purified and then enters the air purification chamber upward through the flower plate holes, Then it enters the main outlet pipe through the switching valve and is discharged by the fan. One of the six adsorption chambers must be in the desorption state, and the other five must be in the adsorption state. Generally, the desorption time is 12 minutes, that is, the adsorption bed responsible for the adsorption work can be desorbed and regenerated once every hour. This work process of the device coincides with the name of the invention zhuanli - a kind of compartment offline desorption bag type adsorption equipment. Its process principle is the same as that of the pulse reverse blow compartment offline bag type dust collector, except that the purification process of the device is "physical adsorption", The bag filter purification process is "physical filtration". The desorption working medium of the adsorption bed is hot air, which is provided by the catalytic combustion device. Generally, the temperature of the hot air is ≤ 150 ℃, which is determined by the boiling point of different VOCs and the saturated vapor partial pressure at the desorption temperature.
The microwave ultraviolet water treatment equipment adopts filters with multiple filter layers, whose primary purpose is to remove the sediment, rust, colloidal substances, suspended solids and other substances with particles of more than 20um in the raw water, production Microwave liquid sterilization Manual valve control or full-automatic controller can be selected for a series of operations such as back flushing and forward flushing. Ensure the quality of water produced by the equipment, and extend the service life of microwave and ultraviolet water treatment equipment manufacturers. Microwave liquid sterilization programme Check whether the power is cut off and the plug is firmly inserted. Check whether the wiring plug of the low-voltage switch of the microwave ultraviolet water treatment equipment falls or fails to work so that the power contact cannot return. Check whether the connecting wire of each terminal falls off, and check whether the water pressure of tap water is too low, so that the low-voltage switch does not work.
It is mainly used for the gas purification of asphalt, rubber, fertilizer, coking, city gas, metallurgy, building materials, carbon ceramics and other industries, while removing impurities such as tar, dust, water mist, etc., to achieve the dual effect of material recovery and gas purification, which also plays a vital role in ensuring the normal and stable operation of equipment in the later section of the process flow. In addition, It is mainly used as pretreatment device for comprehensive organic waste gas treatment.
