Scrap Plastic Pyrolysis Machine Equipment for disposal of used tires
Are waste tire refinery equipment polluting the environment?
Waste Tire Refining Equipment is an environmentally friendly non-polluting equipment that can handle used tires. This equipment converts waste tires into fuel, carbon black and steel wire by means of pyrolysis.machinery and equipment production of waste tire refining equipment attaches great importance to its own environmental protection system, mainly reflected in the four aspects:
First, the water treatment:
Part of the condenser water, without any pollution.
Another part of the dust is water, is the circulating water, only evaporation, no emissions.
Second, the exhaust treatment:
1, is the feed when the feed port leakage of a small amount of water vapor and a small amount of oil and gas, by the oil hood recovery by the second combustion into the dust treatment,
2, the second is the coal when the dust from the fan to the dust collector to deal with the chimney discharge, to ensure that dust emissions to meet the relevant standards.
3, is the reactor out of the C4 below the normal temperature, atmospheric pressure can not be recycled gas by the firewheel from the pipeline into the furnace by the gas gun burning, both energy saving and environmental protection. In the production process, the equipment is fully sealed state of operation, phosphating fluid without any smell.
Third, the waste treatment:
1, is discharged from the reactor residue, the high temperature non-toxic and tasteless, can be used for carbon black work can also be used for building materials.
2, is the remaining coal slag, can be used for building materials, both without any emissions.
Fourth, the noise treatment: equipment selection of low noise fan, noise less than 60 decibels, power part of the noise and the feeder noise are not more than 50 dB.
Waste tires can be made into powder by crushing process. Now used in the production of powder method are dry grinding method, low temperature grinding method and wet grinding method. The main difference between the different methods of making the powder is that the particle size range is different.
Dry grinding method, low temperature grinding method and wet grinding method made of powder particle size range of 013 ~ 115,01075 ~ 013 and 01075mm below. Most of our country uses dry process to produce rubber powder, and through the activation treatment to be applied, such as has been built with an annual output of 10,000 tons of industrial production at room temperature smelting fine powder production line.
The use of low-temperature grinding method to Ukraine as the representative of the United States, Germany and Australia and other countries have established factories, this method of frozen media for liquid nitrogen. Has also been jointly developed the process technology. In addition, the China Aviation Industry Corporation 609 Institute of self-developed "air frozen rubber powder production equipment" has been identified, the principle of air expansion refrigeration, without the use of liquid nitrogen.
The wet process is developed by the British Rubber and Plastics Institute, referred to as PAPRA method, the particle size of the prepared powder is 01002 ~ 01020mm, the reinforcing effect is good, the equipment used is the disc colloid mill, the powder can not only be incorporated into the glue Material to replace part of raw rubber, but also with plastic and asphalt mixed well, can be widely used in various types of rubber and plastic products and highway construction.
In addition, the powder can also be used to modify the plastic to increase the flexibility made of thermoplastic elastomer. Recycled gum is regenerated by thermal degradation or chemical degradation. Traditional methods of regeneration are oil and water. Waste tires made of recycled rubber are mainly used in developing countries where the raw rubber resources are scarce and the labor costs are relatively low. Developed countries due to cost and environmental factors, production decreased year by year, such as the German recycled rubber only 1% of the disposal of waste tires.
The newly developed microwave desulfurization regeneration method is a breakthrough in the regeneration technology, the method is dry desulfurization, no pollution, and product quality is better. At present, the developed countries recommended the method is to wear out the powder using a special surface treatment to replace the raw rubber. Such as Malaysia's De2link series of surface modifier, mixed with powder can improve the use of powder performance. China is a large producer of recycled rubber, with an annual output of more than 300,000 tons of renewable rubber, the main use of traditional oil and water oil method, high cost, serious environmental pollution. The use of new renewable or modified powder is China's recycled rubber industry is worth studying the subject.
