Abstract
The utility model discloses a diesel engine tail gas filtering device which comprises a first casing and a second casing which are coaxially connected. An air inlet connection ring connected with an exhaust pipe of an engine in a matching mode is arranged at one end of the first casing, a first connection ring connected with the second casing is arranged at the other end of the first casing, and a second connection ring connected with the first connection ring through a bolt in a matching mode is arranged at one end of the second casing. The filtering device made of a ceramic nanometer material and in the shape of a circular truncated cone on the whole is connected onto the second casing at the position of the inner periphery of the second connection ring, the end portion of the filtering device stretches into the first casing, and the filtering device has a bottom face and a lateral wall face. A sensor used for measuring the state of tail gas in the first casing is installed on the lower portion of the first casing. The area of the lateral wall face of the filtering device is relatively large. After tail gas enters the first casing, the gas directly impacts the bottom face, a part of gas flow on the lateral wall face is relative slow, the filtering device is not easy to block by carbon particles in the tail gas, and the filtering device is longer in service life compared with a single-plane filtering device.
Description
Technical field
The utility model relates to automobile exhaust gas processing apparatus, especially a kind of engine exhaust gas processing unit.
Background technique
The advantages such as diesel engine is large with its power, efficiency is high, fuel economy obtain increasingly extensive application.But along with the fast development of motor, the tail gas of motor acting discharge is also increasing rapidly, and diesel engine conventionally burning does not have petrol engine abundant, and tail gas exists larger harmfulness, and a large amount of exhaust emissionss, in air, can cause serious pollution to air.Therefore need a kind of device that tail gas is processed without discharge.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existing for prior art, provides a kind of simple in structure, the diesel engine vent gas filtrating equipment that vent gas treatment is effective.
For realizing the object of the utility model, be achieved by the following technical solutions: a kind of diesel engine vent gas filtrating equipment, include the first housing and second housing of coaxial connection, first housing one end is provided with the air inlet connecting ring being connected with engine exhaust pipe, the other end is provided with the first fastener rings being connected with the second housing, and second housing one end is provided with the second fastener rings being connected by bolt with the first fastener rings; The filtrating equipment that an entirety is the ceramic nano material of truncated conical shape that is connected with in week that is positioned at the second fastener rings on the second housing, the end of filtrating equipment is stretched in the first housing, and filtrating equipment has the side wall surface of the bottom surface thickness identical with bottom surface with one; Described the first lower housing portion is provided with to measure the sensor of the first housing inner exhaust gas state.
As preferred version: described sensor is sensor of dust concentration.
Compared with prior art, the beneficial effects of the utility model are: by the filtrating equipment of ceramic nano material is fixedly connected on the second housing, in the time that being connected with the first housing, the second housing can complete like this installation of filtrating equipment simultaneously, filtrating equipment is truncated conical shape in addition, the area of filtrating equipment is larger like this, and the area of side wall surface is relatively large, after tail gas enters in the first housing, gas directly impacts on bottom surface, side wall surface part air-flow is relatively slow, be not easy to be stopped up by the carbon granule in tail gas, the filtrating equipment of single plane relatively, longer service life.

Embodiment
With reference to the accompanying drawings embodiment of the present utility model is made a detailed explanation below.
Shown in Fig. 1 and Fig. 2, a kind of diesel engine vent gas filtrating equipment described in the present embodiment, include the first housing and second housing of coaxial connection, first housing one end is provided with the air inlet connecting ring being connected with engine exhaust pipe, the other end is provided with the first fastener rings being connected with the second housing, and second housing one end is provided with the second fastener rings being connected by bolt with the first fastener rings; Between the first fastener rings and the second fastener rings, connect by six groups, three road bolt.The filtrating equipment that an entirety is the ceramic nano material of truncated conical shape that is connected with in week that is positioned at the second fastener rings on the second housing, the end of filtrating equipment is stretched in the first housing, and filtrating equipment has the side wall surface of the bottom surface thickness identical with bottom surface with one; Described the first lower housing portion is provided with to measure the sensor of the first housing inner exhaust gas state.Described sensor is sensor of dust concentration.In the time of carbon granule excessive concentration in the first housing, signal is transferred to controller by sensor of dust concentration, controller gives the alarm by display unit or acoustic-optic alarm, user can pull down this filtrating equipment and remove in the first housing and surperficial carbon granule and the dust of filtrating equipment, makes filtrating equipment have longer working life.
Claims (2)
1. a diesel engine vent gas filtrating equipment, it is characterized in that: the first housing and the second housing that include coaxial connection, first housing one end is provided with the air inlet connecting ring being connected with engine exhaust pipe, the other end is provided with the first fastener rings being connected with the second housing, and second housing one end is provided with the second fastener rings being connected by bolt with the first fastener rings; The filtrating equipment that an entirety is the ceramic nano material of truncated conical shape that is connected with in week that is positioned at the second fastener rings on the second housing, the end of filtrating equipment is stretched in the first housing, and filtrating equipment has the side wall surface of the bottom surface thickness identical with bottom surface with one; Described the first lower housing portion is provided with to measure the sensor of the first housing inner exhaust gas state.
2. a kind of diesel engine vent gas filtrating equipment according to claim 1, is characterized in that: described sensor is sensor of dust concentration.
