Abstract
The utility model relates to a treating device for the exhaust gas, the heating, the muffling and the purification of internal combustion engine. The device has the functions of exhaust gas, residual heat, heater and muffling purifier. The heater makes the smoke obtain the first grade resistance muffling at the time of heating, and an intake and anexhaust perforation muffling pipes and the honeycomb purifying agent are arranged in the muffler; the smoke obtains multigrade damping muffling and purification. The utility model has the advantages of compact structure, and multiple functions.
Description
The utility model relates to a kind of I. C. engine exhaust heating, noise elimination and purification plant.
The silencing and purifying device of I. C. engine exhaust generally has structures such as perforated pipe, expansion chamber, and be provided with catalyzer on flue gas channel, makes flue gas obtain simultaneously to eliminate the noise and purify.Because delivery temperature is higher, is unfavorable for catalytic reaction, so the part silencing apparatus also adds the exhaust cooling unit.The inventor discloses a kind of exhaust heat of internal combustion engine heating device in Chinese patent 89200290.5, utilized the waste heat of exhaust, but also needed the adjunction silencing apparatus in use, makes the internal combustion engine exhaust system complex structure.
The purpose of this utility model is to provide a kind of multi-functional I. C. engine exhaust treatment device, and is simple and compact for structure, realizes heating, noise elimination and purification simultaneously.
This multi-functional I. C. engine exhaust treatment device is at silencing purifier of the direct connection of smoke discharge pipe one end of exhaust heat switch, this silencing purifier shell is a cylindrical shape, be connected with the exhaust heat exchanger shell, the part that the smoke discharge pipe of heat-exchange device inserts in the silencing apparatus is the perforated pipe of a band side opening, the silencing apparatus the other end is provided with the perforation outlet pipe, is provided with cellular catalytic purification agent between the inlet and outlet perforated pipe of silencing apparatus.
The sidewall small aperture of the inlet and outlet perforated pipe of silencing apparatus is 2.5-3.2mm, and the honeycomb hole of cellular purifying agent is 1.8-2.1mm.
Its carrier tool ceramic body of used cellular purifying agent, carrier surface is active purifying agent, preferred rare earth purifying agent.
The working mechanism of this multi-functional exhaust gas treatment device is the high-temperature flue gas heat exchanger of flowing through earlier, and in heating simultaneously, flue gas volume is amplified, and flow velocity reduces, and obtains one time reactive muffling; Flue gas respectively through the aperture of air inlet perforated pipe, the honeycomb hole of purifying agent and the aperture of outlet pipe, obtains three times damping sound-deadening again in silencing purifier, and CO and HC are purified.Because heat exchanger and silencing apparatus are united use, the structure that heat exchanger can be simplified silencing purifier to the cooling and the noise elimination effect of flue gas need not be provided with complicated devices such as dividing plate expansion chamber in silencer chamber.
The utility model is described in further detail with regard to drawings and Examples below.
The heater with waste heat that heat exchange in the accompanying drawing (7) adopts the inventor to be provided in Chinese patent 89200290.5, silencer cylinder (3) is connected with heat exchanger (7) outer wall, silencing apparatus suction tude (6) and outlet pipe (4) are perforated pipe, the axis normal of two pipes is provided with multi-layer honeycomb shape purifying agent (5) in the tube chamber (10) of silencing apparatus.The high temperature and high speed flue gas enters flue gas chamber (8) from the smoke inlet (1) of heating heat exchanger (7), obtains the one-level reactive muffling; Flow into tube chamber (10) through noise elimination air inlet perforated pipe (6) again, arrive exhaust cavity (2) through purifying agent (5) honeycomb aperture and smoke evacuation perforated pipe (4) then, obtain multistage damping sound-deadening, last flue gas is discharged from floss hole (1), cool air enters from the A end of heat exchanger (7), discharge from the B end, access warm facility.
The utility model compact structure, function is many.Engine start just can make in the compartment temperature rise about 10 ℃ in 5 minutes, the row of harmful gases such as CO and HC and reach related standards, and the noise of fume emission mouth is useful on the various internal-combustion engine vehicles and uses below 80db.
Claims (3)
1, a kind of I. C. engine exhaust treatment device comprises heat exchanger and silencing apparatus, it is characterized in that:
(1) silencing apparatus is located at heat exchanger fume emission mouth one end, and its cylindrical shell is fixedlyed connected with the heat exchanger outer wall,
(2) air inlet and exhaust piper is the noise elimination perforated pipe of being with the sidewall aperture in the silencing apparatus,
(3) between the silencing apparatus air inlet and exhaust piper, be provided with cellular purifying agent.
2, exhaust gas treatment device according to claim 1 is characterized in that the inlet and outlet perforated pipe sidewall small aperture of described silencing apparatus is 2.5-3.2mm, and the honeycomb aperture of described purifying agent carrier is 1.8-2.1mm.
3, by claim 1 or 2 described exhaust gas treatment devices, the active ingredient that it is characterized in that described fume-clarifying agent is the rare earth purifying agent.
