How to reduce the environmental pollution of waste tyre pyrolysis plant?

The old type tire to oil pyrolysis plant

The waste tyre pyrolysis plant can crack the waste tyres, waste plastics and waste rubbers into fuel oil, which not only solves the environmental problems caused by the traditional landfill or combustion of the waste tyres, but also brings considerable profits for us. However, if the waste water and waste gas generated by the waste tyre pyrolysis plant are not handled well, it will also pollute the environment.

Environmental pollution caused by the old type tire to oil pyrolysis plant

DOING Company often receives consultations from customers who want to purchase  environmentally friendly waste tyre pyrolysis plants. Many of the early waste tire refineries are often filled with black smoke, and they can be smelled in a few miles. In recent years, with the gradual strictness of environmental standards in various countries, many less environmental friendly waste tire refineries have been shut down.

So, how to reduce the environmental pollution of waste tyre pyrolysis plant?

DOING environmentally friendly waste tyre pyrolysis plant

1. To reduce the environmental pollution of waste tyre pyrolysis plant, we should choose legal environmentally friendly waste tyre pyrolysis plant. The old type tire to oil pyrolysis process is a serious threat to people and the environment, due to its simple process, unadvanced equipment, and lack of necessary safety system. Henan DOING has developed environmentally-friendly waste tyre pyrolysis plant combined years of experience in manufacturing waste recycling machinery. Unlike the old type tire to oil pyrolysis plant, environmental waste tyre pyrolysis plant is legalized in all aspects and has advantages. DOING environmentally-friendly waste tyre pyrolysis plant is equipped with oil-water separator, water-seal, safety valve, automatic alarm system, explosion-proof valve and other devices to ensure 100% safety during tire pyrolysis process. DOING environmentally-friendly waste tyre pyrolysis plant has passed ISO9001, ISO4001 international quality and CE environmental protection system certification. It has been exported to more than 50 countries and regions such as Africa and Europe, and has been highly praised by domestic and foreign customers.

DOING tail gas cleaning system

2, To reduce the environmental pollution of waste tyre pyrolysis plant, the tail gas should be treated properly. The main component of the exhaust gas is non-condensable gas such as C1-C4, which is very flammable. This part of the exhaust gas can be directly recycled to heat tire cracking reactor to save other fuel. But in the tail gas, there are also some harmful emissions to the air. For example, H2S gas is produce very bad smell when burned, which is harmful to both the air and human body if directly discharged into the air. In this regard, DOING introduced a desulfurization and deodorization tower system, which is specially used to remove H2S gas, and also removes some NOx, COx, SOx gas, which can help customers completely solve the problem of factory smell and emission pollution.

DOING pulse dust collector

3. To reduce the environmental pollution of waste tyre pyrolysis plant, it is necessary to treat the smoke generated during the waste tyre to oil pyrolysis process. Firstly, water type dedusting system is commonly used in the market. DOING’s water type dedusting system for waste tyre pyrolysis plant is designed with 3-level high pressure spraying system, which can well handle the black smoke generated during the tire pyrolysis process to meet environmental standards. If the fuel is coal, firewood, or heavy oil, and the smoke is large, a pulse dust removal device can also be used. The pulse dust collector is a dry dust collector, which does not require water and more than 99.9% dust will be collected.

Circulating cooling water

4. To reduce the environmental pollution of waste tyre pyrolysis plant, it is necessary to treat the waste water generated by the waste tyre pyrolysis plant, which include cooling water and dust removal water. The condenser of DOING waste tyre pyrolysis plant adopts a tubular design, with oil in the tube and water outside the tube. Water and oil are in zero contact, and cooling water can be recycled to achieve zero wastewater discharge.

DOING water type dedusting system circulating dedusting water

The 3 level high pressure spraying system of DOING professional water dust scrubber, which could wash the dust and impurities from the smoke. Because the smoke is acidic, it is necessary to add some caustic lime into the dedusting waster pool before reuse. After acid materials react with caustic lime, the impurities will be settled down, the upper water will become clean and could be used again. Using the principle of the connected device, the clean water in the first pool is filtered to the second filter pool. When the water level of the second filter pool reaches a certain height, the clean water automatically flows into the third filter pool. Then, the water collected through the third filter pool is again pumped into the water dust scrubber for recycling. So dedusting water is also for circulation use, no consumption, no discharge.
