The combined type pulverization injection device is characterized in that the inner sleeve is in clearance fit with the outer sleeve, the fitting faces of the inner sleeve and the outer sleeve are sealed through the two O-type sealing rings respectively, annular liquid supply space is formed by the inner sleeve, the outer sleeve and the two O-type sealing rings, a chemical agent injection hole is formed in the outer sleeve and communicated with the annular liquid supply space, the inner wall of the inner sleeve is of a Venturi pipe structure, and 3-36 pulverization nozzles are evenly distributed on a middle-position line of a conical surface of a diffusion frustum at a Venturi pipe outlet, connected through threads, communicated with the annular liquid supply space and perpendicularly installed on the conical surface of the diffusion frustum. The combined type pulverization injection device has the advantages of being simple in structure, convenient to machine, good in pulverization effect and stable, and also has the advantages of being convenient to disassemble and assemble and capable of reducing the using amount of chemical injection agents by more than 5-25%.
Description
Technical field
The utility model relates to the natural gas transport field of petrochemical industry, particularly a kind of natural gas line combined type atomizing and filling apparatus.
background technique
In the oil gas course of conveying of oil, chemical industry, different requirements due to technique, often in natural gas line, inject the different chemical injectants such as some a small amount of or micro-liquid corrosion inhibitor, alcohols and odorant class, the chemistry injectant quality of mixing with rock gas, has directly affected the utilization ratio of chemical injectant.The atomizing and filling apparatus of existing natural gas line injectant is complex structure not only, and dismounting is extremely inconvenient.
summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of natural gas line combined type atomizing and filling apparatus of simple in structure, easy accessibility is provided.
The utility model is achieved like this: a kind of natural gas line combined type atomizing and filling apparatus, by to being clipped in the inner sleeve between two flanges of pipeline, overcoat, nozzle and two groups of " O " RunddichtringOs form, it is characterized in that: inner sleeve coordinates for intermittently coordinating with outer inner room, inner sleeve and overcoat are sealed respectively the fitting surface of inner sleeve and overcoat by two groups of " O " RunddichtringOs, and in inner sleeve, between overcoat and two groups of " O " RunddichtringOs, form an annular for liquid space, having put a chemical agent hand-hole outward communicates for liquid space with annular, the inwall of inner sleeve is venturi tube structure, atomizer nozzle is by being threaded on the conical surface of diffusion frustum of Venturi tube outlet.
The ratio d/D of the flowing hole diameter d that the structure proportion of the overcurrent curved surface of the Venturi tube of above-mentioned inner sleeve inwall is Venturi tube and the D of natural gas line diameter is 0.65～0.99, the ratio L/d of flowing hole length L and flowing hole diameter d is 0.25～6, and the angle of throat δ that frustum is shunk in import is 45 °～150 ° with the angle of the angle of flare β of outlet diffusion frustum.
The quantity of above-mentioned atomizer nozzle is 3～36.
Its beneficial effect is: simple in structure, easy to process, advantage that atomizing effect is good and stable not only, also has easy accessibility and can reduce the good result of 5～25% chemical injectant consumption.
Accompanying drawing explanation
