Multiple-effect reaction furnace for PVC production and working method thereof

Abstract

The invention discloses a multiple-effect reaction furnace for PVC production. The multiple-effect reaction furnace comprises a preheating furnace, a heating furnace, a cooling furnace and a waste heat recovery mechanism; one side of the preheating furnace is connected with the heating furnace, the side, away from the preheating furnace, of the heating furnace is connected with the cooling furnace, the cooling furnace is provided with the waste heat recovery mechanism, and the waste heat recovery mechanism is connected with the preheating furnace; the waste heat recovery mechanism comprises aheat conveying pipeline and a heat storage bag body; and the multiple-effect reaction furnace further comprises a protective layer and a detection mechanism. The invention further discloses a workingmethod of the multiple-effect reaction furnace for PVC production. On the one hand, the method of heating time dividing and multi-time heating is adopted, the problem that a reaction furnace needs tobe heated for a long time is solved, thus, a product is always in the flowing state, production continuity is achieved, and the production efficiency is high; and on the other hand, modularized protection panels are provided, that is, the modularized protection panels can be quickly dismantled from the furnace body, the scrap cost is reduced, in addition, enough protection can be provided in time,automatic leakage prevention is achieved, and the practicality is high.

Description

technical field [0001] The invention belongs to the field of compound reaction equipment and technology, in particular to a multi-effect reaction furnace for producing PVC and its working method. Background technique [0002] PVC material is a kind of plastic decoration material. It is the abbreviation of polyvinyl chloride material. It is a thermoplastic polymer polymerized by vinyl chloride monomer. It has light weight, heat insulation, heat preservation, moisture resistance, flame retardancy, and simple construction. features. Due to the variety of specifications, colors and patterns of PVC materials, it is very decorative, and is widely used in production and life. As an indispensable reaction furnace in the production of PVC materials, it not only has a huge demand, but also is the object of continuous human and physical research by various enterprises. [0003] With the development of industry and the progress of science and technology, the current reactor is develop...
