Abstract
The utility model mainly relates to a structure of gasification nozzle which is used by a non-catalytic hydrocarbonylation gasification stove. The sliding sealer of gasified nozzle comprises an inner jet tube and an outer jet tube of multi-flow passage gasification nozzle. The main feature is also that the connecting of the inner jet tube and the outer jet tube is provided with a sliding sealer. Because the sliding sealer is adopted, when the temperature changes, the requests of heat expansion and contraction of the inner jet tube and the outer jet tube can be guaranteed and the service life of the jet tube can be extended. Furthermore, the sliding seal eliminates the displacement errors caused by the different temperature contrasts of a nature gas pipe and an oxygen hose to avoid the large stress due to temperature created in the nozzle body. The operation nozzle can be installed and removed conveniently gate through the flange opening on the top of the nozzle to guarantee the normal rise in temperature of the operation nozzle installed through the gasification nozzle and the normal operation of the operation nozzle removed. That the examination and repair of nozzle through opening the nozzle and the replacement of the end of the ejector nozzle of the nozzle can be convenient through the spacer flange.
Description
Technical field:
The utility model relates generally to the structure of non-catalytic oxidation method vapourizing furnace with gasification nozzle.
Background technology:
In the prior art, the vapourizing furnace gasification nozzle of synthetic ammonia installation nucleus equipment is the patented technology and the complete system import of offshore company in the past.In service in production operation, because running environment is High Temperature High Pressure, the jet pipe of gasification nozzle all adopts being connected of machinery, and when temperature changed, jet pipe was fragile.Keeping in repair this nozzle needs to send to abroad through the patent merchant, expends a large amount of financial resources and time.
Summary of the invention:
The purpose of this utility model is to avoid the deficiencies in the prior art part and sliding sealing device that a kind of gasification nozzle is provided.
The purpose of this utility model can be by realizing by the following technical solutions: a kind of sliding sealing device of gasification nozzle, the inner nozzle (1) that comprises multithread road gasification nozzle, outer nozzle (4), its principal feature are also to include in the junction of inner nozzle (1) and outer nozzle (4) to be provided with sliding sealing device (A).
The sliding sealing device of described gasification nozzle (A) is that the inwall at outer nozzle (4) is provided with boss or pad, on the boss of the outer wall of inner nozzle (1) and outer nozzle (4) inwall or pad, be provided with and compress wear ring (5), which is provided with gasket (3), joint flange (2) is placed in inner nozzle (1) and is connected with outer nozzle (4), and the flange of joint flange (2) is pressed on the gasket (3).
The boss that the inwall of described outer nozzle is provided with is a conical surface.
The beneficial effects of the utility model are, owing to adopted sliding sealing device, when temperature changes, have guaranteed the requirement of expanding with heat and contract with cold of inside and outside jet pipe, have prolonged the work-ing life of jet pipe.In addition, sliding seal has been eliminated the displacement difference that natural gas tube and oxygen hose differing temps difference cause, avoids producing big thermal stress at this nozzle body; By gasification nozzle top flange mouth, can install and dismantle the nozzle that goes into operation easily, guarantee that gasification nozzle installs the go into operation normal running of nozzle of the normal intensification of the nozzle that goes into operation and dismounting; By spacer flanger, can overhaul or change nozzle spout end opening nozzle easily.
