A waste rubber and plastic product and a cracking treatment method comprising the resin component product, wherein the cracking treatment is performed by using a cracking furnace, wherein: the cracking furnace body is provided with a plurality of cracking chambers, and each of the cracking chambers is The side is provided with a heating fire wall parallel thereto, and each of the heating fire walls is provided with a plurality of fire chamber type combustion chambers, and a plurality of regenerators are disposed at a lower portion of the cracking furnace body, and the top of the regenerator chamber and the fire channel The bottom of the combustion chamber is connected by a two-way air passage; the bottom of the fire chamber is provided with a gas nozzle; the top of the cracking chamber is provided with a charging port and a cracking gas collecting port, and the upper part of the cracking gas collecting port is set a gas device, a sealing furnace door is arranged at two ends of the cracking chamber; a dual-purpose gas collecting channel is arranged at a lower portion of the regenerator; a scraping device is used in the waste rubber and plastic workshop to pulverize, magnetically select and then feed the scrap The warehouse is used to open the charging port cover on the cracking furnace, and the plurality of charging ports are simultaneously distributed to the cracking chamber on the cracking furnace body; the gas pipe is mixed with gas and air to be combusted, and is passed through the regenerator. After the hot air reaches the combustion chamber and the gas is burned, the heat of combustion is transferred to the cracking chamber through the heated fire wall, and the temperature of the cracking chamber is maintained at 600-1400 ° C to crack the material therein; the air introducing system is started, and the cooling system is guided. The cracked gas enters the oil and gas recovery and separation device, and the cracked gas is separated into fuel oil and combustible gas through the oil and gas recovery and separation device; the oil and gas separator, the condenser and the oil water separator may be disposed in the oil and gas recovery and separation device; the separated combustible gas can be accessed The natural gas cabinet is then supplied to the combustion chamber through the gas pipeline; the flue gas generated by the combustion enters the chimney through the ventilation controller and the branch flue; after the material in the cracking chamber is cracked, the push slag truck and the slag-starting vehicle start the furnace door to be hanged The device picks up the door, and the residue is pushed into the slag-carrying vehicle by the slag-carrying device, and the slag-carrying vehicle guides the residue to the slag-carrying vehicle, and the slag-carrying vehicle and the slag-carrying vehicle start the furnace door lifting device to close the furnace door on both sides of the cracking chamber. The slag truck transports the residue to the carbon black workshop, separates the carbon black and the scrap steel, and completes the whole process of cracking.

2. The cracking treatment method according to claim 1, wherein: a sustained release agent is selected according to physical properties and chemical properties of the waste material for reducing cracking speed, and the sustained release agent is coke powder or pebbles. The slag, the weight ratio of the waste to the sustained release agent is 10 to 70: 90 to 30.

3. The cracking treatment method according to claim 1, wherein: an electric tape unloading trolley is disposed on one side of the cracking furnace body, and the charging device is used to start the furnace door picking device to pick up the door, and then use The unloading trolley fills the charging material into the charging guide device, and the charging material is sent into the cracking chamber by the slag pushing device.

4. The cracking treatment method according to claim 1, wherein: a belt scraper conveyor is arranged on the side of the cracking furnace body, and when the material in the cracking chamber is cracked, the slag pushing truck and the slag guiding device are pushed. The car starts the door picking device to pick up the door, and the residue is introduced into the belt scraper conveyor through the slag guiding device by the slag pushing device, and the residue is transported to the carbon black workshop by the belt scraper conveyor.
