Abstract
The utility model provides an automobile tail gas emission reduction device. The device comprises a tail gas filter and a tail gas discharger which are actively connected, and are connected with an exhaust pipe, and is characterized in that the external layer of the tail gas filter is provided with a thermal insulating layer; soft materials are in encircling and overlapping arrangement along the inner wall in a cavity of the internal layer of the tail gas filter; a solid particle staying space is arranged in the cavity of the tail gas filter; filtering layers are placed in the tail gas filter; each filtering layer is in overlapping placement. The automobile tail gas emission reduction device has the advantages that by applying the device, large particle solid molecules generated in the incomplete combustion of gasoline can be filtered, so that the pollution to air is effectively reduced; in addition, the thermal insulating layer on the outer side of a hose can also cool discharged tail gas; meanwhile, in combination of treatment to the high temperature tail gas by the tail gas discharger, the purposes of cooling and reducing pollutant emission are realized.
Description
Technical field
The utility model relates to the vehicle exhaust emission reduction device for gas simple filtration and cooling effect.
Background technique
Present automobile exhaust filter exists configuration design practicality not strong, does not solve dense black smoke and high temperature that motor vehicle emission goes out.And be not very practical to all motor-driven fuel combustion vehicles, only solved part motor vehicle emission problem, can not effectively solve pollution problem.
Summary of the invention
The purpose of this utility model is to solve all oil-fired vehicles exhaust emissions and the design to the automobile exhaust pipe producing.
The utility model is for achieving the above object, the technological scheme of taking is: a kind of vehicle exhaust emission reduction device, comprise exhaust gas filter and tail gas discharge device, the two is flexibly connected, and is connected with outlet pipe, it is characterized in that: the skin of exhaust gas filter is provided with thermal-protective coating, in the cavity of internal layer, along inner wall surrounding stack, be provided with flexible material, in the cavity of exhaust gas filter, be provided with solid particle parking space, in the inside of exhaust gas filter, be placed with filter layer, each filter layer is stack placement.
Described flexible material is flexible pipe.
Described flexible material is for hindering the solid particle of exhausting air, and described tail gas discharge device has the effect of cooling and filtration to the tail gas of motor-driven fuel combustion vehicle discharge.
Described exhaust gas filter is at the latter half part of outlet pipe.
Described tail gas discharge device is tubular structure.
The filter layer of described exhaust gas filter is for vertically placing or laterally place one of two kinds.
Described vehicle exhaust emission reduction device is built in the inside of outlet pipe, at the front end of exhaust gas filter and the position being connected with tail gas discharge device, has additional filter screen, and exhaust gas filter is identical with the radius of tail gas discharge device.
Described tail gas discharge device front end is provided with the flexible pipe with circular soft material near the position of filter screen, in order to the tail gas of discharge is shunted.
The utility model has the advantage of: utilize vehicle exhaust emission reduction device, can filter out the large particle solid molecule that gasoline produces in partial combustion process, effectively reduce the pollution to air.In addition, the thermal-protective coating in flexible pipe outside also can be lowered the temperature to the tail gas of discharge, and meanwhile, the processing in conjunction with tail gas discharge device to high-temperature tail gas, reaches the object of cooling, reduction pollutant emission.

Embodiment
specific embodiment 1
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of vehicle exhaust emission reduction device, comprise exhaust gas filter 1 and tail gas discharge device 2, the two flexible connection, exhaust gas filter is socketed on outlet pipe, the skin of exhaust gas filter is provided with thermal-protective coating 5, in the cavity of internal layer, along inner wall surrounding stack, be provided with flexible material 6, in the cavity of exhaust gas filter, be provided with solid particle parking space 7.Flexible material plays inhibition to the discharge of solid particle, after solid particle is adsorbed by flexible material, along with vibrations and the Action of Gravity Field of automobile rests on solid particle parking space.Here solid particle parking space can be the special groove arranging on flexible pipe, or all can in the space that the flexible material being wound around disperses out.
tail gas discharge device is tubular structure, and its skin is also thermal-protective coating, along inwall, is vertically arranged with adsorption cotton 7, at the end of tubular structure, is provided with solid particle parking space.
Working principle of the present utility model is: during tail gas process equipment first portion, action time, distance is longer, process has the loss of heat, insufficient the discharged solid particle of fuel oil is had to filtration simultaneously, tail gas is through second portion when discharge, utilization be the effect that the working principle of respirator reaches filtering gas.
specific embodiment 2
Specific embodiment 1 is with the difference of specific embodiment 2: tail gas discharge device is tubular structure, and its skin is also thermal-protective coating, along inwall, is horizontally arranged with adsorption cotton.
specific embodiment 3
Described vehicle exhaust emission reduction device is built in the inside of outlet pipe, at the front end of exhaust gas filter and the position being connected with tail gas discharge device, has additional filter screen 9, and exhaust gas filter is identical with the radius of tail gas discharge device.Vehicle exhaust emission reduction device can adopt the mode of draw-in groove 4 to be connected with outlet pipe, and the mode that also can adopt screw 8 to connect is connected with outlet pipe.
specific embodiment 4
Specific embodiment 4 is with the difference of specific embodiment 3: described tail gas discharge device front end is provided with the flexible pipe with circular soft material near the position of filter screen, in order to the tail gas of discharge is shunted, plays cooling, reduces the object of discharging.
It in the utility model, is the outlet pipe that adapts to difformity, type; to the shape of the shape of exhaust gas filter and tail gas discharge device, can do certain adjustment; this adaptations does not need creative work; just the routine of the art is replaced; variation to various shapes does not repeat one by one at this, all thinks and belongs to protection domain of the present utility model.
