Spiral discharging machine 11 entrance is connected with solid split product receiving hopper 10 discharge port, and outlet connects tr or warehouse.Spiral discharging machine 11 comprises discharge screw 32, discharging screw channel, water-chilling plant and discharging drive-motor 30.Discharge screw 32 rotating speed can utilize frequency transformer to realize adjustable to reducing motor frequency conversion.The screw thread of discharge screw is converging form, to set up second material envelope, stops may revealing of splitting gas further.Discharging screw channel is designed with water-cooling structure, and the inner chamber of discharge screw axle also will be designed to water-cooling structure if desired, to guarantee that the cooling temperature of solid split product reaches requirement.Spiral discharging machine rotating speed is adjustable within the scope of 5-50rpm.Its high and low level gage whether rotated by being arranged on receiving hopper controls, and rotates when being in high charge level, stall when being in low material level.
Described control device comprises control and the molar behavior control of microwave generator, realizes setting and the control of input microwave power; The setting of discharge quantity, fabric thickness and control; The setting of pyrolysis time, temperature, pressure and control; The speed setting of each driving reducing motor and control; The statistics of energy expenditure and cracking ability and form etc.Whole cracking process can realize operate continuously by control device.
Present invention also offers and use above-mentioned disc type microwave
continuouslythe method of cracker cracking waste old or tire, comprising:
The waste old raw material of powdery or bulk (size≤10cm) will be ground into, be poured in storage tank and store;
Raw material, under the stirring action of the stir shaft of storage tank, through rotating blanking valve, by being arranged on cracking top of chamber and extending downwardly through the opening for feed of upper flange and nonmetal sealing plate (i.e. top, cracking chamber), is delivered on rotating-disk;
Along with the rotary unloading of rotating blanking valve, rotating-disk rotates simultaneously;
The microwave generator be arranged on upper circular flange sends microwave and is mapped on raw material makes it carry out cracking through nonmetal sealing plate; Cracking oil gas and solid product are derived by solid product drawing mechanism after being arranged on the cracking oil gas vent of cracking cavity side and cracking.Because rotating blanking valve is trapezoidal cross-section, its rotor is taper, thus can lay waste old on disk continuous uniform.Rotor speed is adjustable within the scope of 5-15rpm, and disc rotation speed is adjustable within the scope of 0.1-0.01rpm, and the laying depth of waste old on disk is adjustable within the scope of 5-15cm.Blanking ability realizes by regulating the rotating speed of rotary unloading valve rotor, and the laying depth of waste old on disk realizes by the rotating speed of the rotating speed and disk that regulate rotary unloading valve rotor simultaneously, and rate of cleavage realizes by regulating the rotating speed of disk.The microwave that microwave generator sends through nonmetal sealing plate from top to bottom, uniaxially is injected on waste old and makes it carry out cracking.Cracking cavity is provided with thermopair and pressure unit, and the temperature and pressure being detected body of wall inside by control device in real time changes.According to the feature of microwave, cracking can be carried out at the temperature lower than conventional thermo-cracking mode.As: cracking temperature can carry out at 300-350 DEG C.Can be tiny structure in cracking cavity, preferred cracking pressure carries out under 50-250Pa.So both can promote the quality of cracked oil, the pressure that split product post drop is cooled can have been alleviated again, save energy consumption.The quantity that temperature in cracking process controls by regulating microwave generator to open realizes.Pressure-controlling realizes by regulating the rotating speed (not marking in figure) of the blower fan be arranged on the pipeline connecting cracking cavity oil gas vent and after-treatment device.Pyrolysis time is different according to the kind, size, laying depth etc. of waste old.General within the scope of 20-60min.Three kinds of products are obtained, respectively: inflammable gas, liquid oils and carbon black after waste rubber cracking.The ratio of products therefrom is approximately inflammable gas 40%(weight), liquid oils 10%(weight), carbon black (comprising other solids component) 50%(weight).The cracking oil gas of deriving can enter into oil gas after-treatment device (figure does not mark) via pipeline, adopts conventional equipment of the prior art, does not repeat them here.
Rotating-disk often rotates a circle, and namely completes a cracking process.From just starting to enter cracking process to stone on rotating-disk, after disk rotary circles, cracking process terminates, and the solid product after cracking will be exported.Blanking due to waste old is continuous print, and the derivation conveying of the solid product therefore after cracking is also continuous print.Solid split product machine of deriving can adopt spiral to derive form, and while disc rotary, derive machine screw rod and also will rotate, rotating speed is adjustable within the scope of 5-50rpm.Solid split product is temporary in receiving hopper, is tentatively cooled to temperature about 200 DEG C on the one hand, sets up a defective material envelope on the other hand, avoids oil and gas leakage.Controlled by high and low two level gages to maintain certain storing amount.Receiving hopper outlet is positioned at bottom, is connected with the spiral discharging machine be obliquely installed.The rotating speed of spiral discharging machine is adjustable within the scope of 5-50rpm.Its height level gage whether rotated by being arranged on receiving hopper controls, and rotates when being in high charge level, stall when being in low material level.Screw channel can be designed to jacketed type water cooling, to ensure that drop temperature is less than 100 DEG C, thus the too high and spontaneous combustion of Yin Wendu after preventing solid split product from contacting with air.
