A wet steam generator water-gas mixed sand filter backwashing system

Abstract

The invention provides a wet steam generator water-air mixed sand filter backwash system, which includes a wet steam generator box, a support leg, a heating chamber, a heating wire, a support plate, a stirring gas entering pipe device, and a backwash water storage tank device. Backwash nozzle structure, movable wet steam spray pipe device, waste sand collection bucket structure, flushing water discharge pipe, control cabinet, sand filter layer, reinforcement rod and backwash chamber, the supporting legs are respectively bolted in the wet steam generator The four corners of the lower surface of the box; the heating chamber is integrally arranged at the inner lower side of the wet steam generating box. The setting of the stirring shaft, the stirring rod and the rotating handle of the present invention is beneficial to carry out rotation and stirring, and discharge the gravel entering the air guide row, which facilitates the backwashing operation; the steam water connection is arranged at the lower part of the secondary manual valve, which is beneficial Separate control of backwash water and wet steam water can satisfy both wet steam operation and backwash water.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a wet steam generator water-air mixed sand filter backwashing system. Background technique [0002] Under a certain pressure, the quartz filter filters the water with high turbidity through a certain thickness of granular or non-granular quartz sand to effectively intercept and remove suspended solids, organic matter, colloidal particles, microorganisms, chlorine, and odor in the water. It is a high-efficiency filtration equipment that can reduce water turbidity and purify water quality by removing odor and some heavy metal ions. Quartz sand filter is generally used as pretreatment of reverse osmosis equipment and ultrafiltration equipment, mainly to intercept and adsorb sediment, colloid, metal ions and organic matter. Commonly used filter materials are quartz sand, activated carbon, anthracite, manganese sand, etc. Widely used in various...
