The chemical composition of the obtained pyrolysis oil is similar to that of diesel oil and can be recycled use.
Applications
Pyrolysis technology is widely used in the treatment of oil sludge. It is a new type of technical method commonly used in the harmless treatment of oil sludge. It can effectively recover the oil resources in the oil sludge, and it is not easy to produce secondary pollutants, so that Realize the recycling of oil sludge and the recycling of waste. The final pyrolysis temperature of oil sludge is 550°C, and the oil yield is about 15-50% depending on the type of oil sludge. The chemical composition of the obtained pyrolysis oil is similar to that of diesel oil and can be recycled use. The oil sludge pyrolysis equipment produced by our company has overcome the previous technical difficulties of oil sludge sticking to the wall.
In addition, the equipment is equipped with a tail gas combustion and reuse device, which is environmentally friendly and saves fuel. And ensure that there is no discharge of three wastes. The equipment takes natural gas as fuel as an example (pyrolysis oil can also be used), the equipment is equipped with a dust collector, the gas discharge is guaranteed to meet the standard, the entire cooling system circulates water, and no waste water is discharged. In terms of product quality and value, the pyrolysis equipment is a good solution. The problem of garbage pollution will not cause secondary pollution, and it will also create huge economic benefits while solving the problem.
The main application areas of this product are:
- Oil sludge treatment
- Waste oil treatment
- Waste plastic treatment
- Waste rubber treatment
- Waste tire treatment
- Medical waste treatment
System composition and process principle
The system takes the heating host as the core, including the host system smoke and dust purification system, cooling system, oil collection system, and combustible waste gas recovery system.
- Firstly, the sludge to be processed is transported to the inside of the main engine through a shaftless screw conveyor or a pump body (depending on the flow state of the sludge), and the furnace door is sealed. With the heating of the furnace, the sludge is gradually decomposed inside the main engine. In view of the sludge has High viscosity, easy to coke and stick to the wall, the main engine is designed with an anti-coking device, which uses the sliding friction of the inner wall structure of the scraper to solve the problem of sticking to the wall, preventing the equipment from manually cleaning coke every few days.
- After the petroleum hydrocarbon components in the oil sludge are decomposed by pyrolysis, high-temperature steam is formed and enters the gas distribution drum, and part of the heavy oil components and mechanical impurities are decondensed, and then enter the cooling system. Inside, the combustible waste gas generated in this process that cannot be liquefied under normal temperature and pressure is recycled to the furnace through the combustible waste gas recovery system, and is supplied to the main engine for heating.
- The soot generated during the combustion process is processed by the soot treatment system. The soot treatment system includes alkaline water, high-pressure atomizing nozzles, and Ball magnetic rings and other materials. The gas that meets the standard is discharged through the smoke pipe to meet the environmental protection emission standard.
- Through high-temperature pyrolysis in a closed environment, the effective oil in the sludge is separated and recycled. Then, under a high-temperature and oxygen-free environment, the oil content of the residue is controlled below 3‰ (actually 63ppm), which fully meets the environmental protection requirements.
Process flow
| Step 1: Feeding | According to the cause of sludge or the state of existence, liquid or solid-liquid mixed sludge can be injected into the heating host using a suction pump, and solid can be injected into the heating host using a shaftless screw feeder , close the loading door after loading. | |
| Step 2: Heating | Use natural gas and non-condensable gas to heat the reactor evenly, and the temperature will gradually rise to about 260 degrees after heating for about 2 hours. The oil goes into the intermediate tank. | |
| Step 3: Non-condensable gas treatment | Non-condensable gas (C1-C4 components) flows into the oil tank together with the oil, and this part of non-condensable gas passes through 2 water-sealed fire arresting devices and 1 fire arresting device Finally, it goes into the furnace and is fully burned by the burner, which can also save a large part of fuel. | |
| Step 4: Smoke and dust treatment | All the smoke and dust produced by combustion are pumped into the general dust removal system by a special induced draft fan for treatment. The treated smoke and dust are white water vapor without black particles, and then the water vapor will enter industrial purification The device carries out standard emission treatment to ensure that the emitted smoke and dust emissions meet the emission standards required by Huanbai. | |
| Step 5: Slag discharge | After the temperature of the reaction kettle drops below 80 degrees, open the slag discharge door, connect the automatic slag discharge machine to start slag discharge, and the discharged slag is transported to the slag storage bin by the negative pressure air conveying equipment through the pipeline , to ensure that the slag discharge process is dust-free. | |

- The waste residue after pyrolysis can meet the emission standard required by environmental protection the oil content of 2%.
Warnings
Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
