Solid-liquid separation system and device provided with system

Abstract

The invention discloses a solid-liquid separation system and a device provided with the system. The solid-liquid separation system comprises a drying box and a heat conducting oil tank, wherein a drying rack tube is arranged in the drying box and processes a material in a heat insulating process, the heat conducting oil tank comprises a plurality of electric heating tubes for heating heat conducting oil and provide a heat source for the drying box. After the heat conducting oil is heated by the heat conducting oil tank, the oil flows into the drying rack tube of the drying box and used for heating the material, water and an organic solvent evaporate in the heating process, separation with the material is achieved, finally the heat conducting oil flows back to the heat conducting oil tank again for reheating. The inside of the drying box is a negative pressure environment. On one hand, boiling points of the water the organic solvent are reduced, and the water the organic solvent are evaporated out at lower temperature; on the other hand, formation of sticky film wrapped air bubbles in the drying process of waste paint residues is destroyed, so that the dried waste paint residues arein honeycomb block shapes, the core wrapping problem is solved, thorough dryness is achieved, the working efficiency of the solid-liquid separation system is effectively improved, and the solid-liquid separation system has higher drying efficiency and is environmentally friendly and economic.

Description

technical field

[0001] The invention relates to the technical field of sludge drying, in particular to a solid-liquid separation system and equipment with the system. Background technique

[0002] With the development of industries such as automobiles and home appliances, there are more and more industrial wastes. How to effectively deal with these industrial wastes has become an urgent matter for various manufacturers, and the cost of occupying the earth's resources is also getting higher and higher, especially waste Proper treatment of paint slag and reduction of waste paint slag are imminent.

[0003] There are also a lot of researches in China trying to utilize them as resources, but in the existing technologies, some are purely for the recovery of organic solvents, without considering the pollution caused by the process to the environment, and some have uncertain safety factors in the process of processing, and some In the process of processing, mucous membrane wrappin...
