Sludge-sand separation and dehydration integrated oily sludge and sand reducing device

Abstract

The invention provides a sludge-sand separation and dehydration integrated oily sludge and sand reducing device. According to the invention, a storage pool is connected with the liquid inlet of a cyclone separator through a pump and a pipeline; the top part of the cyclone separator is provided with a chemical addition opening which is connected with a chemical tank; the sludge outlet of the central part of the cyclone separator is connected with a sludge storage pool; the sand outlet of the bottom part of the cyclone separator is connected with a sand storage pool; the sludge pool is connectedwith a vibrating sieve; the liquid phase outlet of the vibrating sieve is connected with a dehydrator; the solid phase outlet of the vibrating sieve is connected with the sand storage pool; the solidphase outlet of the dehydrator is connected with the sand storage pool; the liquid phase outlet of the dehydrator refluxes to a storage pool; and the vibrating sieve and the dehydrator are fixedly arranged on a conveyor belt which is fixedly arranged above the sludge storage pool. The sludge-sand separation and dehydration integrated oily sludge and sand reducing device provided by the inventionhas the following advantages: particle sizes of sludge are effectively separated and controlled within the range of small particle sizes; the efficiency of reinjection can be effectively improved; andthe cost of reinjection is reduced.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an integrated oil and sand reduction equipment for mud and sand separation and dehydration. Background technique [0002] Oil sludge sand profile control and reinjection technology is a scientific method of processing and utilization simultaneously. It is based on the idea of ​​"coming from the formation and returning to the formation", and it is an effective way to solve the way out of oil sludge sand. However, the current sludge reinjection process does not effectively separate the sludge particle size, and controls the particle size within a small particle size range. Instead, the scheme of reinjection after all stirring is adopted. After a long time of reinjection, it is easy to cause the permeability of the formation to decrease, the reinjection pressure to increase, and reinjection to be difficult. It is necessary to replace and increase the mud injection well more f...

However, the current sludge reinjection process does not effectively separate the sludge particle size and control the particle size within a small particle size range

Instead, the scheme of reinjection after all stirring is adopted. After a long time of reinjection, it is easy to cause the permeability of the formation to decrease, the reinjection pressure to increase, and reinjection to be difficult. It is necessary to replace and increase the number of mud injection wells more frequently; the sand with large particle size in the sludge Severe wear and tear on the pump head of the injection pump, requiring frequent replacement of the pump head, reducing pump efficiency and increasing operating costs
