Description

A kind of starting motor-driven vehicle tail vapour cleaning, energy-saving device

The utility model relates to starting motor-driven vehicle tail vapour purification technics field.

The tail vapour that the motor operation of present most of Motor Vehicle produces directly is discharged in the environment by motor central authorities exhaust steam pipe, owing to being harmful to that fuel oil acting incomplete combustion produces, toxic substance is discharged in the lump with tail vapour environment is produced pollution, the infringement health of human body, the patent No. is 98201147.4 automobile tail automobile tail vapour smoke purifier, being removed motor by tail vapour heat temperature raising in the tail vapour secondary combustion when the annular firing chamber of tail vapour by the annular firing chamber, to discharge in the tail vapour contained major part harmful, toxic substance, but secondary combustion also not exclusively can be removed whole harmful and noxious substances, and the secondary combustion produce power does not have launched machine utilization, waste energy, because single cylinder engine motor vehicle engine discharge tail vapour calorific value is low, it is temperature required that burning cavity can not be heated to the secondary combustion of tail vapour, thereby can not be applied to all motor car engine discharging tail vapour smoke-eliminating purifyings.

The purpose of this utility model provides a kind of novel automobile engines tail vapour cleaning, energy-saving device, can only be applied on the multicylinder engine Motor Vehicle to solve prior art, can not all eliminate motor and discharge the contained harmful and noxious substance of tail vapour, can not make full use of the deficiency that motor is discharged the energy of tail vapour.

The technical solution of the utility model is: it is by central exhaust steam pipe, be sleeved on the expansion chamber sleeve pipe of sealing two ends on the central exhaust steam pipe, tail vapour retort, cooling box is formed, looping cavity between central authorities' exhaust steam pipe and expansion chamber sleeve pipe, dividing plate with holes is arranged in the toroidal cavity, on the expansion chamber jacket exterior central authorities exhaust steam pipe starter gate valve that links to each other with the Motor Vehicle operating mechanism is arranged, tail vapour retort has the odd-side that the purification reaction liquid is dosed inlet by the top, main tank and mixer are formed, main tank, the removing carbon monoxide when working, the odd-side inherence is housed, hydrocarbon, oxynitrides, sulphide, the chemical reaction liquid of harmful and noxious substances such as sulfur dioxide, mixer is by the motor that is fixed on main tank one end, described motor output shaft in the main tank and being separately fixed on this motor output shaft, lower end one just, one is anti-phase to dividing plate composition with holes between impulse impeller and two impellers, on odd-side and the main tank, the lower end has connecting leg to be connected respectively, between cooling box and the main tank upper end, there is connecting leg to connect respectively between the expansion chamber sleeve pipe gas inlet, central authorities exhaust steam pipe and main tank lower end are connected, the expansion chamber sleeve pipe export with engine air vapour filter cleaner between have connecting leg to be connected.The tail vapour that motor is discharged in tail vapour retort with chemical reaction liquid after fully mixing reaction is removed the contained harmful and noxious substance of tail vapour under the mixer effect, in cooling box, condense to remove and purify back gas trace water, heat at expansion chamber afterwards and enter engine air filter, postbacking the motivation firing chamber uses, starter gate valve is at engine start moment assurance engine breathing, starter gate valve cuts out behind the engine start, and tail vapour is closed circulation in this device.

The utility model compared with the prior art its advantage is to discharge tail vapour retort harmful in the tail vapour, the toxic substance chemical reaction liquid because design has dress to remove motor, can discharge contained harmful, toxic substance in the tail vapour by the full scale clearance motor, remove harmful, poisonous gas after cooling box and expansion chamber handle after launched again machine combustion chamber using, conserve energy can be used for any starting motor-driven vehicle tail vapour and purifies.

Accompanying drawing is a kind of starting motor-driven vehicle tail vapour cleaning, energy-saving apparatus structure schematic representation.

Provide the utility model most preferred embodiment below in conjunction with accompanying drawing: it is by central exhaust steam pipe 1, be sleeved on the expansion chamber sleeve pipe 2 of sealing two ends on the central exhaust steam pipe 1, tail vapour retort, cooling box 3 is formed, looping cavity between central authorities' exhaust steam pipe 1 and the expansion chamber sleeve pipe 2, dividing plate 4 with holes and central exhaust steam pipe 1 solid welding are arranged in the toroidal cavity, be fixed with the manual or electronic starter gate valve 5 that can link to each other on the expansion chamber sleeve pipe 2 outside central exhaust steam pipes 1 with the Motor Vehicle operating mechanism, tail vapour retort has the odd-side 6 that the purification reaction liquid is dosed inlet by the top, main tank 7 and mixer are formed, pollutant exhaust hole 8 is arranged at main tank 7 bottoms, mixer is by the motor 9 that is bolted to main tank 7 one ends, described motor 9 output shafts 10 in the main tank 7 and respectively jackscrew just be fixed on these motor 9 output shafts 10 upper and lower end one, one is anti-phase to impulse impeller 11,12 and solid welding two impellers 11 on output shaft 10,12 dividing plates 13 with holes are formed, on odd-side 6 and the main tank 7, the lower end has rubber connecting leg 14 respectively, 15 continuous pipe clamps are fixed, between cooling box 3 and main tank 7 upper ends, between the expansion chamber sleeve pipe 2 gases inlet rubber connecting leg 16 is arranged respectively, 17 connecting tubes fasten, central authorities' exhaust steam pipe 1 is connected dish 18 with main tank 7 lower ends and fixes, and has rubber connecting leg 19 connecting tubes to fasten between 2 outlets of expansion chamber sleeve pipe and the empty institute of the motivation filter cleaner 20.Remove rubber connecting leg 14,15,16,17,19, outside the plastic impeller 11,12, all the other materials all are sheet irons.And this device is fixed on when using afterbody at the bottom of the Motor Vehicle, be connected firmly with the motor exhaust steam pipe.Described starter gate valve 5 is connected with the Motor Vehicle operating mechanism, described motor 9 joins with the motor circuit operating mechanism, dose inlet 23 from odd-side 6 reaction liquids and add chemical reaction liquid in main tank 7 and odd-side 6, when engine ignition, starter gate valve 5 left by the Motor Vehicle operating mechanism, promptly close starter gate valve 5 after the startup, the Motor Vehicle operating mechanism is opened motor 9 power supplys, motor 9 work, the work of drive mixer, motor is discharged tail vapour, enter in the tail vapour retort main tank 7 by central comb 1, at impeller 11,12 and dividing plate 13 effect down, the abundant mixing reaction of chemical reaction liquid and motor exhaust is eliminated in the tail vapour contained all harmful, toxic substance, purify back gas trace water by entering again by pipe 16 to remove in the cooling box 3 afterwards, enter in the prominent sleeve pipe 2 that expands and heat by connecting 17 afterwards, after connecting tube 19 enters in the motor car engine air-strainer, it is work-assisted to postback the motivation firing chamber.
