Embodiment Construction

[0011] In this example, refer to figure 1 , the exhaust emission filter includes a base 1 , an upper cover 2 and a filter element 5 . The center of the upper cover 2 is provided with an air outlet interface 7 connected to the air outlet of the filter element 5. The upper cover 2 and the base 1 are connected by a screw thread, and the upper cover 2 and the base 1 are sealed by a sealing ring 3, and the bottom of the base 1 is provided with an inlet. The air end interface 6; the bottom of the filter element 5 is closed and fixed by the fixing screw 4, the filter element 5 uses glass fiber as the filter medium, and the base 1 envelops the filter element 5 as a whole to form a cavity. The sealing ring 3 is an O-ring.

[0012] refer to figure 2 , the filter element 5 is composed of two top covers 8 with a central hole as the air inlet and outlet, a ring structure, a filter medium composed of glass fibers, and a support 9. The top cover 8 and the support 9 are made of high temper...

Abstract

The invention discloses a tail gas emission filter. The filter comprises a base, an upper cover and a filter core, wherein the center of the upper cover is provided with a gas outlet interface connected with a gas outlet of the filter core; the upper cover and the base are in screwed connection and sealed by a sealing ring; the bottom part of the base is provided with a gas inlet interface; the bottom end of the filter core is closed and fixed by fixed screws; the filter core takes glass fiber as a filter medium; and the filter core is completely sleeved in the base to form a cavity. The filter is simple and small in structure, so that the filter is convenient for assembly and use and is easily maintained; and the glass fiber is used as the filter medium, the glass fiber has the advantages of high-temperature resistance, good gas permeability, big dust containing capacity and the like, and the filter core end face central gas inlet mode existing in the prior filter is changed into the filter core side face gas inlet of the filter, thereby improving the gas inlet efficiency and achieving extremely good filtering effect on tail gas of an automobile, particularly carbon particle impurities.

Description

technical field [0001] The invention relates to equipment for environmental protection technology, in particular to an exhaust gas discharge filter for filtering and purifying exhaust gas discharged from automobile engines. Background technique [0002] Automobile is a means of transportation with a large amount of use. While bringing convenience to people, it emits a large amount of exhaust gas, especially the carbon particle impurities that contain a large amount of harmful gases, causing serious pollution to the environment. If it is not disposed of in time , as time goes on, it will bring great harm to people's life and health. In view of this situation, in order to respond to the national call to protect the environment, people have invented many technologies and equipment for reducing automobile exhaust emissions, such as using the cavity to fill the purification liquid or using catalysts to purify the exhaust gas, which has a certain effect on emission reduction. How...
