Solid-liquid separation system and method and equipment with solid-liquid separation system

Abstract

The invention provides a solid-liquid separation system and method and equipment with the solid-liquid separation system, the solid-liquid separation system comprises a cleaning device, a suction device and a solid-liquid screening device, the cleaning device is used for crushing tank bottom materials, the suction device is used for sucking the crushed tank bottom materials, the solid-liquid screening device is used for carrying out solid-phase and liquid-phase separation on the crushed tank bottom material; the solid-liquid screening device comprises a filtering device and a driving device, and the driving device drives the filtering device to vibrate. According to the solid-liquid separation system disclosed by the invention, the cleaning device, the suction device and the solid-liquid screening device are integrally arranged, so that the flexibility of an application field is improved, tank bottom materials can be sucked and solid-phase substances can be subjected to reduction treatment on a use site, and the transportation cost and the solid-risk treatment cost are greatly reduced; the solid-liquid screening device adopts the driving device to separate solid-phase substances and liquid-phase substances of materials, so that the effect of screening the materials with strong adhesive force, such as oil field sludge, is better.

Description

technical field [0001] The invention relates to the technical field of suction separation devices, in particular to a solid-liquid separation system, method and equipment with the solid-liquid separation system. Background technique [0002] At present, the tank bottom sediments and hardened substances of oilfield fracturing flowback liquid tanks and drilling mud tanks are usually crushed by high-pressure water jets, and a large amount of liquid phase substances will be added during the crushing process. Since the materials cleaned out from the bottom of the tank are hazardous wastes, especially solid wastes are expensive to deal with. Therefore, in order to reduce the transportation cost of materials and solid wastes treatment costs, the solid phase and liquid phase substances are usually separated during the material cleaning process. To realize the reduction treatment of solid phase substances. [0003] The existing solid-liquid separation systems usually use static filt...
