Microwave ultraviolet water treatment equipment The main function is to filter. The water produced is very clean and has no peculiar smell. However, some factors that may affect the filtration of the equipment may occur during use UV water treatment equipment manufacturer Let's introduce the factors that affect equipment filtration:

1、 Suspension concentration

1. High concentration and more filter residue will shorten the effective filtration time in each operation cycle of intermittent production and affect the output.

2. For the operation of continuous vacuum filter, the filter cake generated when the concentration is high is uniform, easy to clean in time, and has little impact on the output.

2、 Temperature

1. During filtration, the suspension temperature is low, the viscosity is high, and the filtration speed is slow. The filtration temperature of crude oil generally does not exceed 70 ℃.

2. The viscosity of liquid is an exponential function of temperature, which decreases significantly with the increase of temperature. Temperature rise is a simple measure to reduce the viscosity, but too high temperature is easy to oxidize the oil.

3、 Operating pressure

1. Most of the impurities in the crude oil are incompressible impurities. The operation pressure is high and the filtration rate is high.

2. If the suspended solids in the oil are composed of colloidal substances, with the increase of pressure, the void in the filter cake becomes smaller, the filtration resistance gradually increases, and the filtration speed drops rapidly. Therefore, the pressure must be determined according to different situations.

4、 Filter media and filter aids

1. 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.

2. 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 oil industry are mostly woven media, commonly used 20 yarn 5-8 ply canvas, twill, ordinary white muslin and other cotton fabrics.

3. Chemical fiber products such as 130 #, 240 #, 260 #, 261 # polyester filter cloth and 828 # vinylon filter cloth are commonly used. Those with more warp and weft strands are used for crude oil filtration, while those with less strands are used for essential oil filtration. For some filters with high requirements, a layer of white fine cloth or flannelette is required to cover the coarse filter cloth.

microwave Ultraviolet water treatment equipment It can filter bacteria, viruses, heavy metals, etc. from the water. According to the theoretical analysis and filtering practice of equipment filtering, there are many filtering factors that affect it. You can have a simple understanding, and then carry out maintenance.
