Embodiment
A kind of self-generating negative pressure diesel oil vehicle exhaust particle capture device, including air inlet pipe 1, one-way control valve, reduction of speed drop
Press blast tube 2, negative pressure powder collection cylinder 10, gas ejector 3, it is characterised in that the reduction of speed that two groups structure is identical, quantity is equal
Decompression blast tube 2 is uniformly staggeredly reversibly mounted in disengagement chamber 14；Reduction of speed decompression blast tube 2 include coaxial decompression outer tube 25 with
Inner tube 22 is depressured, the leading portion of decompression inner tube 22 is located in decompression outer tube 25, and two tube cavities connection, the front end of decompression outer tube 25 is provided with
Filter cone net 24 is crossed, is depressured between the rear end of outer tube 25 and the decompression lateral surface of inner tube 22 and is provided with the equally distributed return port of two or more
26；The air inlet 21 of two groups of rear ends of decompression inner tube 22 is respectively communicated with left independent air chamber 12, right independent air chamber 5, left independent gas
Room 12 taps into tracheae 1 by air intake branch 8, one-way control valve 27, and right independent air chamber 5 taps into tracheae by one-way control valve 1
1；Negative pressure powder collection cylinder 10, negative pressure powder collection cylinder 10 are accessed in the axial gas outlet 23 that filter cone net 24 is crossed on decompression outer tube 25
Interior screen pipe 9 is connected with the outside insertion end of negative pressure catheter 11；The return port 26 of two groups of reductions of speed decompression blast tube 2 respectively with a left side
Air-purifying chamber 12, right air-purifying chamber 4 are connected, and left air-purifying chamber 12 and right air-purifying chamber 4 are again respectively by one-way control valve 3 16, unidirectionally controlled
Valve 4 17 accesses main pipe 15；Main pipe 15 connects the main-inlet 31 of gas ejector 3, negative pressure entrance respectively with negative pressure catheter 11
32.One-way control valve 1 is with one-way control valve 3 16 with the same opening and closing of start or stop, and one-way control valve 27 and one-way control valve 4 17 are same
Start or stop can only open one of which with being opened and closed during two groups of one-way control valve work.
The self-generating negative pressure diesel oil vehicle exhaust particle capture device of the present invention, is a set only one of which tail gas air inlet
With the locking device of a tail gas gas outlet, tail gas air inlet is connected with enmgine exhaust, diesel oil vehicle exhaust warp
Negative pressure filtration is crossed, the exhaust gas clean environment firendly finally discharged from tail gas gas outlet, because the present apparatus is to be depressured blast tube by reduction of speed
Commutate reduction of speed decompression, the online a small amount of particle of self-cleaning cone, in the case where powder collection net cylinder is underfilled with particle, can effectively make
With.
