Since 2012, haze has repeatedly appeared in many cities in China. The main culprit is the particulate matter (PM) in the air. Generally speaking, particulates are classified according to their diameters, such as PM10, PM2.5, even PM1, PM0.5, etc., which we can often hear. In particular, the most common inhalable particulate matter, PM2.5, has become a regular guest in the media reports. In 2015, Jing Chai's "under the sky" is more shocking and haze is very harmful to human body. We feel that the haze problem can not be ignored and environmental problems can not be ignored.

Black smoke particulate matter (PM) in diesel exhaust is the cause of air pollution. As a device that can significantly reduce PM, it is only convenient to install on the muffler. Therefore, exhaust particulate collector technology has become a vehicle technology of great concern.

The diesel particulate filter (DPF.Diesel Particulate Filter) is a wall flow type honeycomb ceramic with cordierite or SiC as raw material. The main component of the exhaust gas from diesel engine is carbon particles. The particulate trap is installed in the diesel exhaust system to reduce the particles in the exhaust. The device (PM) has a filtration efficiency of more than 90% for carbon particles, and the soluble organic component SOF (mainly high boiling point HC) can also be partially arrested. The working principle of the particulate trap: by alternately blocking the ends of honeycomb porous ceramics, the PM is removed by using ceramic wall holes.

The diesel engine is equipped with an oxidation type catalyst, which uses precious metals such as platinum (PT) and palladium (Pd) as the catalyst, which mainly reduces the SOF content in the particulate emission and thus reduces the emission of PM. At the same time, the HC in the exhaust can be effectively reduced. The CO. oxidation catalyst can remove 90% of the SOF, thereby reducing the PM emission by 40% to 50%. The processing efficiency of HC and CO can reach 65%-85%. Catalytic oxidation technology has good effect on removing soluble organic components (SOF) in diesel engine emission particles, that is, the catalytic converter is added in the diesel exhaust system, and the oxidation reaction of SOF is converted to CO2 and H2O under the action of platinum, rhodium and palladium and other noble metal catalysts or rare earth catalysts, and usually it is removed. The efficiency is up to 80%. At the same time, it can also remove harmful substances such as HC and CO in tail gas, and effectively reduce harmful substances into the atmosphere.

The company specializes in the production of diesel engine exhaust particle collector (DPF). The product is based on honeycomb ceramic carrier material technology and uses cordierite or SiC as raw material. It can play an excellent interception effect for diesel engine exhaust particulate matter (black smoke). It is widely used in diesel automobile and urban public. Automobiles, heavy trucks, mining trucks and forklifts are effective ways to solve air pollution.

The features of this product:

1. Large specific surface area: ensure sufficient contact between exhaust gas and catalyst.

2. Stable water absorption: ensure that the catalyst is firmly and evenly attached to the surface of the collector and does not cause waste due to excessive coating.

3. Warming up: after the engine is started, the temperature of the carrier can reach the catalyst's active temperature in the shortest time.

4, low exhaust resistance: requires the carrier to reduce the exhaust resistance of the engine, so as to ensure that the performance of the engine is not affected.

5. High intensity: as the working environment of the carrier is on the bumpy car, the carrier is required to have high strength without being damaged by external forces.

6. Good assembly: the carrier is a part of the exhaust assembly. Only a good appearance and precise size can ensure the perfect assembly.

The number of holes and wall thickness of diesel exhaust particulate collector can be processed according to user requirements.
