Abstract

A noise damping flam arrester of tail gas filtration is provided, of which a machine body is formed by three pipes of different diameter and length. The diameter of a main pipe is four times longer than the diameter of an air feeder and the diameter of a center pipe is two times longer than the diameter of the air feeder. The extremity of the air feeder is connected fixedly with an umbelliform cone, of which the nose points at the diameter center of the extremity of the air feeder. Four filters are arranged into a circle interlayer in turn. The other end of the main pipe is provided with a plug. A vent-pipe drills through the plug and then connects with the main pipe. The main pipe and the plug adopt the double-layer wall with a vacuumized middle. The novel device has good effects of tail gas filtration, noise damping and fire prevention. With a low cost and convenient cleaning, the utility model can be used on various motor vehicles abroad as the tail gas purification device.

Description

Tail gas filtering noise reduction flame damper

The utility model relates to motor-vehicle tail-gas filtration, noise reduction, refractory protection.

Current mobility car discharge tail gas has seriously been polluted environment, solution to this problem mainly is that tail gas filter is installed, the filtrating equipment that relatively is suitable for does not also occur at present, Chinese patent disclose for No. 002534614 a key name be called " tail gas clean-up noise reduction flame damper " technology introduction the cartridge type frame of a kind of two ends projectioies, two ends is equipped with wire netting respectively in the tube, stainless steel wool and aluminium silicate wool are housed between two metals in tube, this installs good filtration effect, also some trouble but device proper is removed contamination.

Task of the present utility model is: what overcome prior art is not, design a kind of filtration, noise reduction, flameproof effect good, remove contamination conveniently, do not stop up the tail gas filtering noise reduction flame damper of following car body to use.

Task of the present utility model is that mode realizes: the body of tail gas filtering noise reduction flame damper is not waited by three diameters, the tubing of varying length constitutes, the diameter of main body pipe is four times of suction tude diameter, the center tube diameter is two times of suction tude diameter, be fixed with a umbellate form cone at the suction tude end, the center of suction tude end diameter is aimed in the tip, 4 stainless steels gold cotton and aluminium silicate wool are contained in the filter that constitutes in the steel wire and pack into successively in the circle interlayer between center tube and the main body pipe, the other end of main body pipe is equipped with plug, outlet pipe passes plug and links to each other with the main body pipe, on the wall of main body pipe, be pressed with a rectangular trapezoid-shaped trench, have into dirty hole on the ditch, trapezoidal rectangular groove of weldering on porose one side, sewage draining exit of weldering on the rectangular groove, tighten with the ingot bolt, main body pipe and plug all adopt double-deck arm, and the centre vacuumizes.

The utility model is because motor exhaust directly sprays to the umbrella shape cone by suction tude, air-flow divides to circumference, reduced impulse force like this, tail gas turns back to the other end plug of suction tude again from the interlayer between center tube and the suction tude, again from the circle between the inwall of the outer wall of center tube and main body pipe form interlayer by three layers of stainless steel metal cotton and last one deck aluminium silicate wool, hold back the HC compound in the tail gas, it is dirt, because three pipes of body all are the cylindrical body uses of droping to the ground, stay incessantly dirt on the cylindrical body, the road surface is rugged when being subjected to engine luggine and vehicle driving simultaneously jolts, make thin and delicate especially fiber filter agent produce distortion at any time, form new random tiny micropore at any time, also change the path of tail gas simultaneously at any time, and because dirt does not exist in the filtering agent, pollute all the time and move, enter sewage storage room from pollutant exhaust hole, so the utility model stops up never to the nethermost one side of body, simultaneously, also has the convenience of removing contamination, durable in use; The utility model since filtering agent special thin, be easy to receive tail gas interior heat amount, the CO in the tail gas is burnt fully, reduce the discharge amount of tail gas CO; Because main body pipe and plug all are dual-layer walls, middle vacuum, so the developed area of body wall and filtering agent is very big, many tiny micropores all sound-absorbing are very big, and three layers of meticulous different pipe and interlayer come and go the impulse force that reduces tail gas for three times, so erasure effect the best; Because filtering agent is forced to hold back the HC compound to tail gas, make the dirt and the combustible gas CO that are burning can not be outside outlet pipe while burn, Mars can not spray, so also the best of flameproof effect.

Fig. 1 is the utility model front view.

A most preferred embodiment of the present utility model, as figure, the body of tail gas filtering noise reduction flame damper is by three diameter differences, the tubing of varying length is made, wherein the diameter of main body pipe 1 is four times of suction tude 2 diameters, center tube 6 diameters are two times of suction tude 2 diameters, at the end of suction tude because of being connected with a umbellate form cone 12, the center of suction tude end is aimed in the tip of cone, being contained in the filter that constitutes in the steel wire with 4 by rust steel steel wool 10 and aluminium silicate wool 11 packs in the circle interlayer between center tube and the main body pipe successively, the other end of main body pipe 1 is equipped with plug, outlet pipe 4 passes plug 3 and links to each other with the main body pipe, on the wall of main body pipe, be pressed with a rectangular trapezoid-shaped trench 5, have pollutant exhaust hole 7 on the ditch, trapezoidal rectangular groove of weldering on porose one side, sewage draining exit 8 of weldering on the rectangular groove, tighten with ingot bolt 9, main body pipe and plug all adopt dual-layer wall, and the centre vacuumizes.

Claims

1. tail gas filtering noise reduction flame damper, it has a body, filtrating equipment is housed in it, it is characterized in that: body is not waited by three diameters, the tubing of varying length constitutes, wherein, the diameter of main body pipe is four times of suction tude diameter, the center tube diameter is two times of suction tude diameter, in the end of the suction tude umbellate form cone that is connected, the center of suction tude end diameter is aimed in the tip, 4 stainless steel metal cottons and aluminium silicate wool are contained in the filter that constitutes in the steel wire successively in the circle interlayer between center tube and main body pipe, the other end of main body pipe is equipped with plug, and outlet pipe passes plug and links to each other with the main body pipe, is pressed with a rectangular trapezoid-shaped trench on the wall of main body pipe, have on the ditch and carry out the hole, at porose trapezoidal rectangular groove of one side weldering, sewage draining exit of weldering is tightened with the ingot bolt on the rectangular groove, main body pipe and plug all adopt dual-layer wall, and the centre vacuumizes.
