Embodiment 1

[0011] The main structure of the gas-liquid-solid three-phase separator involved in this embodiment includes a tank body 1, a folded-plate inclined plate 2, an air-cement mixing gap 6, an air-cement separation area 7, a clear water gap 8, a mud collection area 9, and a gas collection area 10. Clean water area 11, outlet channel 12, sludge return pipe 13, reaction area 14 and biogas pipe 15; inside the tank body 1 of the hollow structure, there are several folded plate sloping plates 2 of S-shaped plate structure, The folded plate type slant plate 2 is composed of a slant plate 3, an upper folded plate 4 and a lower folded plate 5. The front end of the inclined plate 3 with an inclined plate structure is provided with an upper folded plate 4 with an L-shaped plate structure bent upwards. The rear end of the inclined plate 3 is provided with the lower folded plate 5 of the L-shaped plate structure bent downwards, the horizontal plane where the top point of the upper folded plate ...

Abstract

The invention belongs to the technical field of biochemical sewage treatment equipment, and particularly relates to a gas-liquid-solid three-phase separator. A main body structure comprises a tank body, folded inclined plates, gas-water-sludge mixed flowing gaps, gas-water-sludge separating zones, clear water gaps, sludge collecting zones, gas collecting zones, clear water zones, a water outlet ditch, sludge reflowing pipes, a reaction zone and biogas pipes; by adoption of a shallow-layer sedimentation theory, the folded inclined plates squeeze and diffuse gas-water-sludge mixed liquid flowingup into the three-phase separator from the anaerobic reaction zone through the gas-water-sludge mixed flowing gaps, biogas is collected in the gas collecting zones and discharged through the biogas pipes, sludge and air-free sludge sink into the sludge collecting zones under the action of gravity and reflow into the reaction zone through the sludge reflowing pipes, and sewage from which the sludge and the gas are removed rises into water collecting zones through the clear water gaps, so that full separation of gas, water and sludge phases is achieved; and the gas-liquid-solid three-phase separator is simple in structure, novel and unique in design concept, high in gas-liquid-solid separation performance, high in practicality and good in hydraulic condition, and can improve the operating stability and the operating efficiency of a three-phase reactor.

Description

Technical field: [0001] The invention belongs to the technical field of sewage biochemical treatment equipment, and specifically relates to a gas-liquid-solid three-phase separator, which is suitable for reactors meeting the technical requirements of sewage anaerobic biological treatment. The area and separation performance realize the efficient separation of mud, water and gas. Background technique: [0002] Three-phase separators are mostly used in upflow anaerobic sludge bed reactors (UASB) in biological sewage treatment to separate digested gas, digested liquid and sludge particles. The digested gas is exported from the top of the reactor, and the sludge particles slide down automatically. It settles to the sludge bed at the bottom of the reactor, and the digested liquid is discharged from the clarification area; the three-phase separator can collect the biogas generated from the reaction chamber under the separator, so that the suspended matter above the separator settl...
