Oxygen compound and some pairs of human bodies generate other dysgenic solid particulate matters.Solid particulate matter complicated component, and have
Stronger adsorption capacity can adsorb various metallic dusts, strong carcinogen BaP and pathogenic microorganism etc., solid suspended particle
Enter human lung with breathing, is trapped in the different parts of respiratory tract, Yi Yinqi respiratory disease；When suspended particulate is run up to
When critical concentration, just it may excite to form malignant tumour；In addition, suspended particulate substance can also directly contact skin and eyes, resistance
The hair follicle and sweat gland for filling in skin, cause dermatitis and eye conjunctivitis, or even may also result in corneal injury.Therefore by vehicle exhaust
In solid particle direct emission in air, it is huge to environmental hazard, seriously affected the life security of people.To sum up, subtract
Few motor vehicle exhaust emission gradually becomes the size for measuring a urban environmental protection ability.
The existing major measure for reducing diesel emission is divided into machine pre-treatment, vent gas treatment after processing, machine in machine.Before machine
Processing mainly improves diesel quality；Emission controls by improving combustion mainly improves combustion process；Machine post-processing mainly utilizes granule capturing
Device (DPF), oxidation catalyzer (DOC) etc. reduce PM discharge amount.However existing machine equipment for after-treatment is complicated, at high cost, absorption
It is ineffective.
Summary of the invention
For the prior art there are above-mentioned technical problem, it is good that the present invention provides a kind of adsorption effect, the simple spiral of structure
The particle separator of water jet absorption diesel engine vent gas in pipe.
To achieve the above object, the present invention the following technical schemes are provided:
A kind of particle separator of water jet absorption diesel engine vent gas in helix tube, including cylinder, two end plates, spiral shell are provided

Firmly；The lower section of cylinder is equipped with catch basin, and the bottom of the cylinder is connected to catch basin, and catch basin is provided with drainage hole.
Preferably, dowel is provided between the bend pipe and tube body.
Preferably, the bottom of the cylinder is connected with multiple coupling tubes, and the inner cavity is catchmented by coupling tube connection
Slot.
Beneficial effects of the present invention:
In use, it is passed through liquid from the water inlet of bend pipe, and liquid sprays in flow process from each hole for water spraying, thus
Water mist is formed in sorption channel.Diesel engine vent gas enters inner cavity from air inlet, moves along spiral helicine sorption channel, tail gas
In particulate matter under the action of water mist, soak weight gain and settle during the motion, water mist and particulate matter sink together
Into the catch basin of bottom, purified tail gas drains into atmosphere from gas outlet.Spiral helicine sorption channel bending is very long, certain
Space in be able to extend the movement routine of tail gas, improve the effect that exhaust particulate object is adsorbed；And water mist can be to a certain degree
On slow down the movement speed of tail gas so that particulate matter is adsorbed more sufficiently.Particle separator structure of the invention is simple, at
This is low.
