Abstract

The utility model discloses an organic silicon cracking device. The organic silicon cracking device comprises a cracking kettle, wherein a slag discharge pool is arranged below the cracking kettle; a feeding hole is reserved on the side of the cracking kettle; a discharge pipe is arranged at the upper end of the cracking kettle; a water-cooling pipeline is sleeved out of the discharge pipe; the discharge pipe is led to a first buffer cylinder; the discharge pipe of the first buffer cylinder is connected to the feeding hole of a water cooler at the upper end of a receiver; the discharge hole of the water cooler is connected to the receiver; the receiver is connected to a second buffer cylinder through a pipeline; and the second buffer cylinder is connected to a vacuum pump through the pipeline. In the organic silicon cracking device, by arranging the pipeline with water cooling and a plurality of buffer cylinders are arranged at the upper end of the cracking kettle and arranging a condenser at the upper end of the receiver, mist generated in a cracking reaction can be effectively converted into liquid, so that environmental pollution is prevented, the product yield is increased, the product quality is improved, and economic benefits are created for enterprises.

Description

A kind of organosilicon cracker

Technical field:

The utility model relates to the chemical industry equipment field, a kind of specifically organosilicon cracker.

Background technology:

Because the high speed development of organosilicon product and countries in the world industry constantly increase its demand, development prospect a slice light that art machine silicon industry is arranged in China, organosilyl kind various in style is nearly more than ten thousand kinds at present, commonly used just have 4000 surplus kind, roughly be divided into 1, raw material (silicon ore), 2, intermediate (DMC) (dimethyl ring siloxane mixture) 3, the three major types of product and goods, wherein silicone intermediate mainly is meant the siloxane oligomer of long thread-shaped body or ring bodies, as octamethylcyclotetrasiloxane (I) 4) dimethyl ring siloxane mixture (I) MC) etc.Organosilicon product and goods, and are dosed the class inorganic silicon and are filled out and pour or modified additive makes organosilicon product by polyreaction by intermediate, mainly contain silicon rubber (high temperature fluidized silicon rubber and room temperature fluidized silicon rubber).All types of silicone oil and secondary processing goods, silicone resin and silane coupling agent four big classes.

Along with the appearance of above product is produced, processing, has been produced a large amount of wastes again in using at it, as: all kinds of seal gums of solidified, various mould, the toys that contain the organosilicon composition, electronic keyboard burr and scrap or the like.So useless silicon rubber has been born.Utilizing useless silicon rubber catalytic pyrolysis to produce organosilicon product is in middle period nineteen nineties, domestic enterprise participates in and invites the expert to explore, prove, develop, produce, extract silicone intermediate (I) MC wherein from useless silicon rubber) production technique, broken the promise that claims the non-renewable utilization of organosilicon refuse by the expert of developed country.On product, alleviated the demand of China to silicone intermediate, on _ technology by former single cracking to a line production technique that rearranges, purifies, filled up and utilized the blank of useless silicon rubber to product.

Cracking is one of topmost link in the production technique, its technical process is that the raw material that will crush is put in the cracking special reactor for 300 kilograms, heating up rises to 180 ℃ of unlatching vacuum pumps when temperature, and this moment, temperature in the kettle was very high, and granular silicon rubber has been transformed into thick shape body by solid.With sulfuric acid and Phenylsulfonic acid by 6% of charging capacity---2% mixes as Cuiization agent, sulfuric acid 18kg, Phenylsulfonic acid 6kg slowly adds in the reactor.When catalyzer touches thick shape body, carry out catalysis rapidly and make organism and inorganics in the thick shape body change the mist body.After mixing acid adds, the rate of air sucked in required of adjusting vacuum is ascending, decide on liquid flow rate, because the effect of vacuum, the mist body is along with vacuum is pumped to condenser, make its pressure and rapid cooling makes the mist body be transformed into liquid, and liquid is entered in the susceptor, be evacuated to one 0.09 (Pa) up to vacuum and reach 200 ℃ of absence of liquid flows or become to drip a shape to 0.1 (Pa) temperature in the kettle, be considered as cracking and finish.Lay down the residue in the still, clear still, feed intake again and continue to produce.With the liquid in the susceptor (thick DMC) can, prepare to rearrange.

Domestic existing cracker, the efficient that its mist body is converted to liquid is not high enough, part effective constituent quilt is arranged along with gas communication is taken in the atmosphere, has both wasted material, has caused environmental pollution again.

Summary of the invention:

For solving the problem that prior art exists, the spy provides a kind of organosilicon cracker, by the pipeline of band water-cooled being set and a plurality of surge tanks is set in the cracking still upper end, and install the mode of condenser additional in receiver upper end, the mist body that can effectively scission reaction be produced is converted to liquid, has prevented environmental pollution, has increased product production, improved quality product, for enterprise has created economic benefit.

The scheme that the utility model adopts:

A kind of organosilicon cracker, comprise cracking still, it is characterized in that: the cracking still below is provided with the deslagging pond, and the cracking still side is provided with feeding mouth, and the cracking still upper end is provided with discharge nozzle, discharge nozzle is set with water cooled pipeline outward, discharge nozzle leads to first cushion dashpot, and the discharge nozzle of first cushion dashpot is connected to the feeding mouth of the water cooler of receiver upper end, and the discharge port of water cooler is connected to receiver, to second cushion dashpot, second cushion dashpot arrives vacuum pump by pipe connection to receiver by pipe connection.

Advantage of the present utility model is:

The utility model is by being provided with the pipeline of band water-cooled and a plurality of surge tanks are set in the cracking still upper end, and install the mode of condenser additional in receiver upper end, the mist body that can effectively scission reaction be produced is converted to liquid, prevented environmental pollution, increased product production, improved quality product, for enterprise has created economic benefit.
