Ordinary-pressure vertical cyclone solid-liquid separation method and equipment

Abstract

The invention discloses an ordinary-pressure vertical cyclone solid-liquid separation method and equipment. The method comprises the following steps: feeding wet materials into a vertical tank body (2) by virtue of a feeding device (1); and stirring the wet materials by virtue of a compound stirring device (3), heating the wet materials by virtue of a heating device (4) of the tank body (2) to evaporate moisture to dry the wet materials to form particles, evaporating the moisture and volatile organic maters in the wet materials through heating and discharging from the top of the tank body (2),and discharging the particles formed after the wet materials are dried from the bottom of the tank body (2). According to the method and the equipment, the space volume is well utilized, the occupiedarea of the equipment is reduced, and the efficiency is relatively high; by utilizing an electric heating manner, the temperature increase speed is high, the pollution is avoided, and the use is convenient; and furthermore, matched facilities such as a steam boiler are not used, so that an equipment system is simplified.

Description

technical field [0001] The invention relates to a solid-liquid separation method for wet pollutants, in particular to a normal-pressure vertical cyclone solid-liquid separation method and a separator.

AI Technical Summary

Problems solved by technology

[0002] At present, the horizontal solid-liquid separation equipment commonly used at home and abroad to deal with wet materials has a large area and poor separation effect.

And the wet material is dehydrated only by centrifugal force, and the moisture content of the treated material is relatively high

[0003] 1. In the existing "vertical" treatment technology, there is a steam heating interlayer on the periphery of the tank body, which is heated by steam at 3 atmospheres or higher to ensure the dehydration rate. Such a tank body is a high-pressure vessel with a large Security risks;

[0004] 2. Heating requires a complete set of supporting equipment such as a steam boiler or a steam heat source

Adds additional difficulties to production operations and lacks flexibility;

[0005] 3. The heating principle is a single heating mode of wall plate contact heat conduction, which is inefficient
