Integrated oily mud wastewater pipe bundle coagulation and separation reactor

Abstract

The invention relates to an integrated oil-contained wastewater pipe bundle coagulation and separation reactor which comprises a reactor main body, a water inlet pipe, a chemical feed pipe, a water outlet pipe, an emptying pipe, an oil recovering pipe and an air purging pipe are arranged on the main body, and a support is used for supporting the main body. A mud storage region, a water baffle plate, a pipe bundle settling region, a fiber bundle coagulation and coarse graining region, a water distribution plate and the like are mainly installed inside the reactor, the reactor is obliquely installed on the support, the mud storage region is located at the lower part inside the reactor main body, the water baffle plate, a pipe bundle, a water partition plate, the pipe bundle settling region and the fiber bundle coagulation and coarse graining region are located at the middle part, and the water distribution plate and an oil separation plate at the upper part form an oil and water separation region. The reactor has good removal and recovery effect on wastewater containing mud and oil, low energy consumption and small land coverage and is flexible to disassemble, assemble and transport, the mud removal rate can reach more than 95% for oil shale washing wastewater and oil field mining wastewater, the oil recovery rate can reach 90%, the grain size of oil in drained water is smaller than 10 mum, and the mud content is smaller than 10%.

Description

technical field [0001] The invention belongs to the technical field of industrial wastewater treatment, and relates to a tube bundle coagulation separation reactor for oily sludge wastewater. The invention is especially suitable for oily, muddy sand industrial waste cement sand removal, oil recovery and utilization in the fields of petroleum exploitation, chemical industry, steel, electric power and the like. Background technique: [0002] Oily sludge wastewater tube bundle coagulation separation reactor is an integrated reactor for waste cement sand removal and oil recovery and utilization developed on the basis of inclined plate sedimentation and coagulation adsorption technology. [0003] Traditional silt-containing sand and oily wastewater are generally treated separately. Among them, mud and sand removal mainly uses the principle of "shallow sedimentation, and advection, vertical flow or inclined plate sedimentation tanks are used to remove mud and sand. Oil removal ma...

AI Technical Summary

Problems solved by technology

[0004] (1) The slick oil is collected by the scraper, the sludge is mixed, and the separation is not complete, which affects the quality of the recovered oil;

[0005] (2) Depending on the pressure of the sedimentation tank or the pump to discharge the sludge, the sludge is not discharged in time and thoroughly, which often causes the sludge to expand;

[0006] (3) Relying on the dosing pool or dosing box for dosing, the water distribution is uneven, and mechanical stirring or pipeline mixers are needed to improve the coagulation effect and increase the cost;

[0007] (4) Civil structures are generally used, and the facilities occupy a large area and cannot be moved

[0008]The above shortcomings limit the popularization and use of traditional processing devices
