Inert gas shielding gas-bearing formation is formed in the entire flared section of the second flared section 31, exhaust gas is formed in inert gas shielding gas internal layer
Stable laminar flow.
When in use, exhaust gas enters the first flared section 21 through exhaust gas inlet 1 to the jet pipe of the application in the present invention, and exhaust gas is passing through
It crosses the first aditus laryngis 23 and the first slot section 22 is accelerated, when 1 pressure of exhaust gas inlet is sufficiently large, 22 exit of the first slot section
Air-flow is up to supersonic speed.Enter 31 rear end of the second flared section of outer layer jet pipe after exhaust gas ejection core jet pipe.Such as Fig. 2 and Fig. 3 institute
Show, gas is generated discontinuous due to the unexpected compression by back-pressure Pt ' (pressure at inert gas spray head) outside core jet pipe
Pressure increase because Pe (outlet pressure of core jet pipe) be greater than Pa (pressure of outer layer jet pipe), exhaust gas be in owe expansion shape
State, exhaust gas prolonged expansion and reduce pressure after core jet pipe out, and pressure is gradually lowered to Pa, and in the second flared section 31 due to
The injection of inert gas spray head 4 forms inert gas shielding gas-bearing formation, and the exhaust gas for spurting into the second flared section 31 is wrapped in indifferent gas
Body protects gas internal layer, and the low pressure of 3 core of outer layer jet pipe concentrates exhaust gas, be not easy to spread, and forms stable laminar flow (Pt in Fig. 2
The pressure at exhaust gas inlet end is represented, the direction of inert gas spray head is identical as core jet pipe direction in Fig. 3).In exhaust gas and inertia
Gas is again speeded up when passing through the second aditus laryngis with the second slot section, sprays (exhaust gas and indifferent gas from outer layer nozzle exit later
Airflow condition of the body in each jet pipe refers to fig. 4 to fig. 6).As shown in figure 3, Pe ' (outlet pressure of outer layer jet pipe) is less than
Pa ' (environmental pressure) will form shock wave in outer layer nozzle exit.When exhaust gas leaves outer layer jet pipe 3 inert gas shielding gas according to
So it is present in outer layer, exhaust gas can make exhaust gas deferred reaction in internal layer, carry out waste gas reaction in the position far from spout, prevent
There is incrustation or blocking spray head in jet pipe tube wall in a large amount of particulate matters such as silica that only waste gas reaction is formed, so as to improve intracavitary
The case where incrustation, reduces maintenance and repair rate.
In conclusion the present invention effectively overcomes various shortcoming in the prior art and has high industrial utilization value.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should be covered by the claims of the present invention.
