Embodiment 1

[0027] see figure 1 and figure 2 As shown, the present invention provides an engine exhaust gas circulation purification and noise reduction system, including a body 1 with a cavity formed inside and placed vertically. An air intake pipe 101 is connected at the top of the main body 1, an exhaust port communicating with the cavity is opened at the top, and an exhaust pipe 102 is connected to the exhaust port. Two partitions 104; the first partition 103 is arranged horizontally above the air inlet, and the length of the first partition 103 is smaller than the inner diameter of the cavity; the second partition 104 is arranged vertically and is connected to the end of the first partition 103 , the length of the second separator 104 is smaller than the distance between the first separator 103 and the bottom of the cavity. Several vertically arranged electrode plates 106 are arranged between the side of the second separator 104 near the air inlet and the inner wall of the cavity,...

Embodiment 2

[0032] see Figure 8 to Figure 9 As shown, the difference between Embodiment 2 and Embodiment 1 is that the inner wall of the cavity is located between the discharge electrode and the bottom of the exhaust pipe with a number of baffles, and the baffle is divided into a through-hole area and a closed area, and the through-hole area is The area is 2 / 3 of the baffle area, and a number of through holes are opened in the through hole area. The closed area on the baffle plate adjacent to the discharge electrode corresponds to the position of the dust collecting plate, and the closed areas on the two adjacent baffle plates are staggered from each other.

[0033] Since the exhaust gas passes through the staggered baffles in the closed area before being discharged, the through-hole area has overlapping parts, so that the exhaust gas passing through the small holes does not directly change direction to be discharged from the exhaust pipe, which greatly reduces the gas to bear before bei...

Abstract

The invention discloses a system for purifying and silencing engine exhaust gas. A first baffle and a second baffle are connected to the inner wall; the first baffle is located above the air inlet and is arranged horizontally, the second baffle is connected to the end of the first baffle and is arranged vertically, and the second baffle is close to the air inlet. A number of vertically arranged electrode plates are arranged between one side of the air inlet and the inner wall of the cavity, and a number of vertically arranged dust collecting plates are arranged between the side of the second separator that is not the air inlet and the inner wall of the cavity. A horizontally arranged discharge electrode is arranged on the inner wall of the cavity above the first separator; an electrostatic generator is arranged outside the body, and the electrostatic generator is respectively connected with the electrode plate, the dust collecting plate and the discharge electrode. The invention has simple structure and convenient operation, and greatly improves the dust removal and purification effect while ensuring the noise reduction effect.

Description

technical field [0001] The invention relates to an exhaust gas treatment device for an internal combustion engine, in particular to an engine exhaust gas circulation muffler system. Background technique [0002] Internal combustion engine is a kind of power machine, which is a heat engine that burns fuel inside the machine and converts the heat energy released into power directly. In a broad sense, internal combustion engines include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines, but also rotary impeller gas turbines, jet engines, etc., but the internal combustion engine is usually referred to as a piston internal combustion engine. The piston type internal combustion engine is the most common with the reciprocating piston type. A piston-type internal combustion engine mixes fuel and air, burns it in its cylinder, and the released heat can generate high-temperature and high-pressure gas in the cylinder. The gas exp...
