Diameter series of activated carbon adsorption tank (mm): 200, 300, 400, 500, 600, 700, 800, 1000, 1200, 1400, 1600, 1800, 2000 2200, 2400, 2600, 2800, 3000, 3200, 3600, 4000Working pressure series of activated carbon adsorption tank (MPa): normal pressure, 0.2, 0.3, 0.4, 0.45, 0.5, 0.65Requirements
5.1 Activated carbon adsorption tank (hereinafter referred to as equipment) shall be manufactured in accordance with JB/T2932. 5.2 The appearance of the weld must be flat and uniform, without defects such as slag inclusions, arc pits and pores, and no slag and spatter should be left. 5.3 When the equipment is a pressure adsorption, there should be an overpressure protection device. 5.4 The equipment is recommended to support the activated carbon in the form of a filter plate, and the flatness tolerance of the filter plate is 5mm. 5.5 The equipment should be equipped with convenient backwashing pipelines and drain ports, and the discharged liquid should not pollute the surrounding area. 5.6 When the pressure difference between the inlet and outlet water of the equipment is greater than 0.05MPa, backwashing should be carried out, and the backwashing intensity is 5~10L/(s·m). When backwashing, there should be protective measures to prevent the activated carbon from being flushed into the pipeline. 5.7 The inlet and outlet of the equipment should be equipped with a pressure gauge and a convenient sampling port. 5.8 When the equipment is a pressure adsorption, an accurate calculation manual should be issued to ensure that the equipment can withstand the maximum working pressure. 5.9 When the equipment is a normal pressure adsorption, a water leak test should be conducted. When the equipment is a pressure adsorption, a water pressure strength test should be conducted at 1.25 times the design pressure (and not less than the design pressure + 0.1MPa). Check the welds and structures. There should be no damage, abnormal deformation or leakage. Carbon steel or stainless steel is recommended for the material of the equipment. When the equipment is a normal pressure and small diameter, it can also be made of organic glass, plastic and glass fiber reinforced plastic.
5.11 In addition to preventing general corrosion, special attention should be paid to preventing electrochemical corrosion. When the equipment is made of carbon steel, before anti-corrosion, the surface treatment should comply with the provisions of GBT8923, the inner surface lining should comply with the provisions of HG229, and the anti-corrosion layer on the inner and outer surfaces should comply with the provisions of JB/T2932.
5.12 When users select activated carbon adsorption tanks, they should make conditional selections and make adsorption isotherms to determine the carbon type and filtration rate, adsorption efficiency and carbon regeneration cycle, etc. The turbidity of the inlet water for water treatment is not more than 5°, and the turbidity of the inlet water for wastewater treatment is not more than 20°. The pH value is recommended to be between 5.5 and 8.5, and there is no oil pollution. In order to ensure the adsorption effect, it is recommended that the empty tower filtration rate be controlled at 5~10m/h, and the carbon layer height should meet the requirements of the adsorption process.
5.13 The structure of the equipment should have sufficient rigidity and strength to withstand the influence of any load that may occur during operation. 5.14 The equipment should be able to be used normally in an environment with an ambient temperature of 0-50℃, a relative humidity of less than 95%, and an altitude of less than 1000m. 6 Test methods
