In recent years, some units blindly reduced equipment costs and increased profits. When planning bag filter, the filter wind speed was advanced. In a short time, the users of stainless steel membrane shell had no obvious response, but greatly shortened the service life of the filter bag. If the temperature of carbon steel filter is too high, the dust removal bag is selected to exceed. What are the skills and functions of carbon steel filters? Let's get to know them together next.
I. Skills and Functions of Carbon Steel Filters
(1) Desalination of brackish water and defluorination of groundwater
Raw water 101 filter Fine filter Electrodialysis device Hollow fiber ultrafilter Ultraviolet sterilizer Product water
(2) Water for preparation of pharmaceutical professional injection and large infusion
Raw Water Activated Carbon Filter Fine Filter Electrodialysis Device Cation Exchanger Anion Exchanger Mixed Ion Exchanger Multi-effect Distillation Water Machine Product Water
(3) Production of purified drinking water and space water
Raw water mechanical filter activated carbon filter fine filter electrodialysis device cation exchanger anion exchanger mixed ion exchanger hollow fiber ultrafilter ultraviolet sterilizer ozone sterilizer product water
2. General Criteria for Selection of Carbon Steel Filters
1. Filter material:
The raw material of the filter is usually the same as the raw material of the technical pipeline connected with it. For different operating conditions, the filter with cast iron, carbon steel, low alloy steel or stainless steel raw material can be considered.
1. Import and export paths:
The import and export diameter of carbon steel filter should not be less than the import diameter of matching pump, usually with the import pipe intersection.
2. Nominal pressure:
Determine the pressure level of the filter according to the maximum pressure that may occur in the filter line.
3. Selection of the number of holes:
The main consideration of carbon steel filter is the size of impurities to be blocked, which depends on the technical requirements of medium flow. All kinds of standard wire mesh size can be blocked look up the table "filter standard".
4. Filter acceptance pressure
The acceptance pressure of carbon steel filter is 0.4-0.6 MPa.
The application of carbon steel filter in wastewater treatment can effectively prevent and control the waste of water resources and promote its economic development. And the water can be recovered after being treated by carbon filter. Direct use of grid to block impurities in water, remove suspended particulate matter, particulate matter, reduce turbidity, purify water quality, descend the system of dust, bacteria and algae, corrosion, so as to achieve the purpose of purified water reuse.
