Embodiment Construction

[0021] Such as figure 1 , figure 2 As shown, a specific embodiment of the porous plate water cap activated carbon filter with anti-activated carbon powder leakage function of the present invention includes a filter body 1, and the filter body 1 can be stainless steel material, or glass fiber reinforced plastic material, or carbon steel material etc.

[0022] The structure of the filter body 1 is the same as that of the prior art. For the porous plate water cap filter, an activated carbon layer 11 and a porous plate water cap structure 12 must be provided, wherein the water cap can be made of ABS or stainless steel.

[0023] In addition, according to specific needs, the filter body 1 is also provided with a water inlet 14 , a water outlet 15 , a forward washing outlet 16 , a backwashing outlet 17 , a backwashing water inlet 18 , etc., as in the prior art.

[0024] The special feature of the present invention is that a fine sand layer 13 is arranged between the activated carbo...

Abstract

The invention discloses a perforated-plate-water-cap activated carbon filter with an activated carbon powder leakage prevention function. The perforated-plate-water-cap activated carbon filter comprises a filter body which is internally provided with a perforated plate water cap structure and an activated carbon layer; a water inlet, a water outlet, a washing waterspout, a backwashing waterspout and a backwashing water inlet are arranged on the filter body; and a fine sand layer is arranged between the activated carbon layer and the perforated plate water cap structure. According to the invention, as the fine sand layer is arranged between the activated carbon layer and the perforated plate water cap structure, the phenomenon of powdered activated carbon leakage during the use of the activated carbon filter is avoided.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a porous plate water cap activated carbon filter with the function of preventing leakage of activated carbon powder. Background technique [0002] At present, water resources are increasingly scarce, and water quality deterioration is becoming more and more serious, especially the pollution of water quality by microorganisms and organic matter. In recent years, in the operation of subcritical units, supercritical units and ultra-supercritical units in thermal power plants, the influence of total organic carbon (TOC) in boiler feed water on boilers and turbines has attracted great attention. Therefore, GB / T 12145-2008 "Water Vapor Quality of Thermal Power Generating Units and Steam Power Equipment" has strict restrictions on TOC indicators in the boiler feed water quality standard. [0003] To make the TOC index meet the standard, microorganisms and organic matter in the ...
