There are two types of waste tire cracking refining equipment: continuous waste tire cracking refining equipment, and intermittent waste tire cracking refining equipment. To understand the difference between these two devices, we must first understand the technical principle of waste tire cracking refining equipment.

The waste tire is placed in a high-temperature atmospheric cracking reactor, and a special catalyst is added. After heating at a high temperature, the oil can be catalytically cracked, non-condensable gas, carbon black, and then the oil is subjected to chemical treatment such as precipitation filtration to remove impurities, and the mixed oil is gradually. Purified into primary diesel.

Conventional techniques for production processes:

1. Add special catalyst to waste oil raw materials, carry out catalytic cracking at medium temperature, and the cracking effect can be achieved by waste oil and various mineral oils;

2. The gas component obtained after cracking is further catalytically cracked in a fixed bed to obtain oil vapor;

3. The oil vapor is fractionated and the gasoline and diesel fractions are separately collected;

4. The gasoline and diesel fractions are separately refined. Through the device that removes impurities, the whole process not only ensures the product quality, but also the equipment investment is simple, the volume can be reduced, the process is simplified, and the production cycle is shortened. The obtained oil has good quality, high transparency, can achieve the same effect as mineral water, has low carbon content, and belongs to unleaded gasoline, which can reach the national standard 93# gasoline standard.


In the disposal of waste:

1. Exhaust gas

The plastic refining equipment is fully burned by the safety device water seal and the gas nozzle, which not only eliminates the exhaust gas pollution, but also saves a lot of fuel; the soot strong ZTC series desulfurization dust collector can be used for soot emission, and the soot discharge can reach GB 13271-2001. standard.

2, waste liquid

Plastic refining equipment oils produce some weakly acidic wastewater during processing (about 50 kg of wastewater per ton of oil produced). After adding neutralization to the neutralization, the neutral wastewater is filtered through three stages to achieve harmlessness, and then discharged to a dedicated evaporation processor (the heat source of which uses the flue heat of the main processor) to evaporate, and more professionally Wastewater treatment plant).

3. Waste solids

After the waste plastic is catalyzed by thermal cracking, there will be some solid residue, which accounts for about 5% to 10% of the weight of the waste plastic. Its main component is crude carbon black. It can be used as a raw material for the production of industrial carbon black, or as a raw material for the manufacture of fly ash bricks (an environmentally friendly building material) by mixing with fly ash from coal-fired power plants.

Pyrolysis refining equipment: a complete set of production equipment for producing waste oil, non-condensable flammable gas and solid products by cracking waste rubber and waste plastic.

Continuous complete sets of production equipment: Continuously send waste rubber and waste plastic into the cracker for cracking, producing oil, non-condensable flammable gas and complete production equipment for continuous export of solid products.

Intermittent complete sets of production equipment: Put waste rubber and waste plastics into the cracker for temperature cracking, and then collect the oil and non-condensable combustible gas, then cool down and discharge the solid products, and carry out the complete production equipment for periodic production.

It can be known that the waste tire cracking refining equipment comprises a continuous waste tire cracking refining equipment and a batch waste tire cracking refining equipment.
