Process for continuous separation of chlorinated polyethylene (cpe) clinker at high temperature

Abstract

The invention aims at providing a process for continuous separation of chlorinated polyethylene (cpe) clinker at high temperature so as to solve the problem of defects in the prior art. The technical scheme of the process is that a high-temperature clinker storage tank, a centrifugal machine and a drying furnace are adopted. The process is mainly characterized in that the temperature of the clinker entering the centrifugal machine is higher than 65 DEG C, the temperature of the clinker after separation is higher than 60 DEG C, moisture content of the clinker is controlled to be lower than 35%, and the clinker enters the drying furnace. The process has the advantage that the temperature of the clinker is above 65 DEG C, the clinker is low in viscosity and easy to separate, the continuous automatically-discharging centrifugal machine is adopted so as to enable the moisture content of the clinker after separation to be below 35%, the clinker enters the drying furnace directly, simultaneously a cooling process of the clinker in a reaction kettle is omitted, a whole production process can be operated continuously, device efficiency can be used fully, energy is saved, emission is reduced, and economic benefit is improved remarkably.

Description

technical field [0001] The high-temperature continuous CPE clinker separation process of the present invention relates to the clinker separation process in the CPE production process. Background technique [0002] The cpe industry is an important industry in the development of the national economy. In the process of producing CPE, the clinker in the reactor must undergo solid-liquid separation before entering the drying furnace for drying. The existing clinker separation process is a normal temperature separation process, the process of which is as follows: normal temperature clinker storage tank→centrifuge→drying furnace, the temperature of the clinker entering the centrifuge is several degrees higher than normal temperature, and the clinker temperature after separation Slightly higher than normal temperature, the moisture content of the material is controlled at about 30% before entering the drying furnace. The disadvantage of this process is that the clinker is highly v...
