Catalytic combustion
The jinker exhaust gas treatment workstation equipment adopts an intelligent automatic control system , which can adjust the power according to production needs to save energy . And it can be intelligently adjusted according to the gas concentration to achieve the greatest degree of energy saving, power saving and consumable reduction. The two energy-saving technologies are superimposed and controlled.
Jinker waste gas station can provide customers with software, software products, trademarks, patents, communication interfaces and open part of communication protocol interfaces, etc., to assist customers in applying for clean production and cloud-based system support technology for enterprises.
The organic waste gas emitted during the spraying process is harmful to the surrounding environment and even human health. The spray paint waste gas is mainly composed of triphenyls (benzene, toluene, xylene), and some also contain esters, ethers, ketones and other components. These volatile organic compounds can cause headaches and nausea in mild cases, and convulsions and coma in severe cases, which can damage the human immune system. In order to effectively solve these problems, the country and some provinces and cities have promulgated a series of laws and regulations and atmospheric environmental protection standards to limit and control the hazards of exhaust gas.
During the painting process, most of the paint sprayed by high-pressure air stays on the workpiece, and other spray particles that do not reach the sprayed surface and the water droplets that dissolve the spray paint particles are suspended in the air, and the volatile organic compounds generated during the spraying process are formed. Spray paint exhaust pollutes the environment. Due to the different solvents used in different paint coatings, the components of the exhaust gas produced during the spraying process are also different. Taking automobile spraying as an example, 15 kinds of VOCs were detected, including benzene series (toluene, xylene, etc.), esters (ethyl acetate, butyl acetate, etc.), ketones (methyl isobutyl ketone) and ethers ( Ethylene glycol butyl ether), etc. Beijing, Shanghai, Guangdong, Jiangsu and other places have formulated corresponding standards for VOCs emissions in the coating industry.
Jinke Green Technology Catalytic Combustion Furnace
Catalytic combustion furnace CO can be directly applied to the purification of medium and high concentration ( 2000mg/m 3 ~5000mg/m 3 ) organic waste gas. It is suitable for the same production line, where the composition of the waste gas often changes or the concentration of the waste gas fluctuates greatly due to different products. The types of organic substances that can be processed include benzenes, ketones, esters, phenols, aldehydes, alcohols, ethers and hydrocarbons, etc.
The catalytic combustion treatment method is to send the organic gas source into the purification device through the action of the induced draft fan, first pass through the dust removal and flame arrester system, then enter the heat exchanger, and then send it into the heating chamber, through the heating device, the gas reaches the combustion reaction temperature, and then passes through The function of the catalytic bed decomposes the organic gas into carbon dioxide and water, and then enters the heat exchanger to exchange heat with the low-temperature gas, so that the temperature of the incoming gas rises to the reaction temperature. If the reaction temperature cannot be reached, the heating system can realize compensation heating through the automatic control system to make it burn completely, which saves energy, and the effective removal rate of exhaust gas reaches more than 96% , which meets the national emission standards.
The device is composed of the host, induced draft fan, inlet pipeline, exhaust pipeline and electric control cabinet. The dust collector is located on the air intake pipe, and the explosion-proof device is located on the top of the main engine. The schematic diagram of the process flow is as follows:
The exhaust gas source of the straight outlet should have a direct exhaust pipeline, controlled by a valve, and the exhaust gas can be directly emptied if necessary (such as: when the purification device is overhauled).
The flame arrester is composed of a special multi-layer metal mesh, which can prevent the flame from passing through and filter out larger particles (dirt) in the gas. It is one of the safety devices of this purification device.
The heat exchanger is a plate heat exchange structure. Its function is to use the heat released by the catalytic reaction to heat the exhaust gas at the inlet, improve the utilization rate of heat energy, and reduce the heating energy consumption.
The preheating chamber adopts an electric heating system to heat up the organic waste gas to the preheating temperature required for the catalytic reaction, and is mainly composed of a heater, a furnace hall, a heat exchanger, and an explosion-proof port;
The burner (optional) uses natural gas indirect heating system to heat up the organic waste gas to the preheating temperature required for the catalytic reaction. It is mainly composed of a burner, a furnace hall, a heat exchanger, and an explosion-proof port; The adjustable burner is composed of a burner, a regulator, a valve group, and an electric control box. The furnace hall and heat exchanger are made of heat-resistant stainless steel.
Thermal resistance is used to measure intake air preheating temperature and purification reaction temperature.
The catalytic bed is composed of multi-layer honeycomb catalyst, which is the core of the device.
The explosion-proof device is a pressure relief method for the diaphragm. When the equipment runs abnormally, it can be cracked to release the pressure in time to prevent accidents.
The fan is controlled by frequency conversion, and the fan is adjusted according to the actual production air volume.
The valve is to control and adjust the size of the gas flow.
Features
1 ) The precious metal palladium and platinum are used as catalysts on the honeycomb ceramic carrier, the purification efficiency is as high as 98% , the catalyst has a long service life, and can be regenerated, the air flow is smooth, and the resistance is small.
2 ) Complete safety facilities: equipped with protection facilities such as fire arrester and dust collector, pressure relief port, and over-temperature alarm.
3 ) Power consumption: when starting to work, preheat for 5-10 minutes at full power, and automatically compensate for heating when the concentration of exhaust gas is low during normal work. When the exhaust gas concentration is ≥ 2g/m³ , the combustion furnace works normally without compensation heating.
4 ) Easy to operate: when the equipment is working, it realizes automatic control and does not need special personnel to guard it.
