Description

High-efficiency thermal cracks desorption reaction furnace

Technical field

The utility model relates to a kind of thermal cracking desorption reaction furnace, refers in particular to one kind and makes full use of reaction hopper heat The high-efficiency thermal in source cracks desorption reaction furnace.

Background technique

It drives auto industry and rubber industry, plastics industry to flourish with the development of the global economy, has every year big Waste rubber, the generation of plastic solidification waste are measured, especially damaged tire is more large, if without appropriately processed or recycling It utilizes, not only causes the waste of resource, and the impact of nightmare can be caused to environment, endanger global soil and Environmental security.If Scrap rubber or tire are handled with burning mode, not only not environmentally and waste of resource, because rubber is petrochemical, are contained about 88% carbon, the carbon black about 30 ~ 40% that is added is 99% pure carbon in formula, therefore, rubber in rubber or tire waste its contain Carbon amounts is high, about twice of coal, and a greater amount of carbon dioxide of output are discharged into atmosphere after burning, is more detrimental to global environmental protection and closes The reduction of greenhouse gas discharge of the heart.In addition, carbon black is petrochemical for Energy Angle, about two tonnes of petrochemical industry oil product can be made One ton of carbon black, therefore carbon black is highly energy-consuming product, but carbon is an extremely stable material, if can recycling and reusing can reduce pole Big energy consumption and waste.

The desorption cracking of solid scrap rubber, plastics is important process method one of of such waste other than incinerating.This Kind mode is after crushing waste, to be desorbed and cracked at a proper temperature, with output gas, oil product and solid carbon black Deng.These products are all the products of high additive value, wherein hydrocarbon of the oil product in rubber, plastics, if rubber Contain natural rubber in glue, is then a kind of raw mass-energy, has sizable benefit to energy-saving and emission-reduction.Above-mentioned oil product can be steamed again with vacuum The method of evaporating isolates light oil and heavy oil etc., more improves its surcharge.But the technical presence that the past cracks scrap rubber Thermal cracking desorption reaction speed it is unevident, the problem of waste of energy, reason is for the pipe reaction furnace in known hot bellows The general design using screw conveyor push raw material (i.e. scrap rubber, plastics), and the furnace body (reaction material of its screw conveyor Slot) it is fixed without rotating, the raw material of desorption to be cracked is by screw conveyor (helical-blade horizontal or with one acute angle of horizontal folder Piece) push, therefore those raw materials always move under water below the lower of the furnace body, however, the hot bellows to furnace body heating are adopted more It is full of hot bellows chamber with the hot gas of high temperature, to heat to the reaction furnace body, the furnace body highest temperature being heated in chamber is to fall In furnace body region against the top, thus the raw material that energy heats move under water in lower section can not be effectively utilized, heating efficiency has It is to be hoisted.

On the other hand, the speed of traditional screw conveyor transferring raw material turns depending on single helical blade conveying axis Speed can not be controlled respectively in this way, which raw material can only be single-rate with the conveying speed in hot bellows before entering hot bellows It is made different conveying speeds, therefore anti-in the raw material feeding section for needing transmission speed fast and the raw material that needs transmission speed slightly slow It between two kinds of speed for answering section, is only capable of work one and takes a house, and the best effective of the desorption cracking of solid scrap rubber, plastics can not be played Rate.
