Description
Technical field
The present invention relates to the concentricity testing devices of a kind of OC distributor diffuser pipe and fumarole, and in particular to one kind is applicable in
Concentricity between the corresponding hole of metal tube whether the detection device within deviation range, be particularly suitable for OC distributor
The concentricity that diffuser pipe and jet pitch of holes are 20~200mm detects and a fairly large number of concentricity is suitble to detect.
Background technique
Oxychlorination reactor is the important equipment of VCM (vinyl chloride) process units, in use, oxychlorination reactor
In OC (spout is closed) distributor it is easy to wear.The main reason for abrasion is that the Concentricity tolerance of diffuser pipe and fumarole is big,
The air-flow of the ethylene and recyclegas that come out fumarole completely liquidates and melts from the oxygen and hydrogen chloride come out with diffuser pipe
Reaction is closed, the air-flow of fumarole, which is directly washed on diffuser pipe with the catalyst inside tower, leads to diffusion pipe abrasion, for a long time
Washing away causes diffuser pipe to damage.Therefore, the key problem for avoiding OC distributor device from wearing is control diffuser pipe and fumarole
Concentricity tolerance is within 1.6mm.Currently, commonly the method for the Concentricity tolerance of detection diffuser pipe and fumarole has 2 kinds.
One, it is measured using angle square, it is specific as shown in Figure 1, the small straight section of angle square 6 is close to 5 edge of fumarole, the observation long straight section of angle square
It is bonded situation on the outside of diffuser pipe 4, thus measured deviation value.This method is related to manual operation factor, influences on measurement result
Greatly, inefficient.Two, as shown in Fig. 2, 7 top outer diameter of pipe fitting tooling is identical as diffusion pipe outside diameter using " convex " type pipe fitting tooling 7,
Pipe fitting tooling, which is accurately placed in fumarole top, ensures that pipe fitting tooling and fumarole are coaxial, then measures diffuser pipe and fumarole
Concentricity tolerance, since there are deviations for the spacing in practical set between diffuser pipe and fumarole, according to the size needs of spacing
The different pipe fitting tooling of production height, the method measurement result is relatively accurate, but inefficient, need to make the tooling of various specifications,
It is cumbersome, while pipe fitting tooling can not fix, movement can occur because of touching leads to measurement inaccuracy.
Summary of the invention
It is an object of the present invention to provide the concentricity testing devices of a kind of OC distributor diffuser pipe and fumarole, being capable of high efficiency
Measurement OC distributor diffuser pipe and fumarole concentricity whether in deviation range.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of concentricity testing device of OC distributor diffuser pipe and fumarole, is made of core pipe 1 and casing 2, described
Core pipe 1 is made of two symmetrical semicircle 3 splits of core pipe semicanal, and the core pipe semicanal 3 is by top for being set in diffusion
The boss composition that semicircle tube body and lower part outside pipe 4 are used to protrude into fumarole 5, the internal diameter of core pipe 1 is diffuser pipe after split
Outer diameter Φ D+1.6mm；The tube wall inclination makes core pipe 1 have taper, the taper and core pipe 1 of 2 inner wall of casing
Taper it is consistent, casing 2 is set in outside core pipe 1 from 1 upper end of core pipe.
Preferably, the semicanal that the core pipe semicanal 3 is integrally formed.
Preferably, the outer wall inclination of the tube body increases tube body wall thickness from top to bottom.
Preferably, the length of the tube body is greater than the spacing of diffuser pipe and fumarole.
Preferably, the boss is in semi-cylindrical, and the radius of boss is equal to the radius of fumarole, it is ensured that 1 lower end of core pipe
It is fixed in fumarole and avoids core pipe mobile, to improve measuring accuracy.
Preferably, the upper surface of the casing 2 is flushed with 1 top of core pipe.
The concentricity that detection device of the present invention is suitable for diffuser pipe and jet pitch of holes is 20~200mm detects.According to expansion
Pressure pipe and the spacing of fumarole determine the height of core pipe.
The permission maximum deviation of the concentricity of diffuser pipe and fumarole is 1.6mm in OC distributor.
A kind of concentricity detecting method of OC distributor diffuser pipe and fumarole, comprising: by casing 2 along diffusion bottom of the tube set
Enter to make casing to be located at diffuser pipe upper outside, symmetrically placed being set in outside diffuser pipe of two core pipe semicanals 3 is pieced together into core pipe
1, and protrude into the boss of 3 lower part of core pipe semicanal in fumarole, it is inserted in casing 2 from 1 upper end of core pipe, if core pipe 1 is smoothly inserted in
In casing 2 and flush the upper surface of casing 2 with 1 top of core pipe, then the concentricity of diffuser pipe and fumarole meets deviation requirement.
Detection device of the present invention is also applied for the Concentricity tolerance between the detection corresponding hole of metal tube.
Beneficial effects of the present invention:
The core pipe of detection device of the present invention is put together by two symmetrical core pipe semicanals, is convenient for from diffuser pipe and fumarole
Spacing in penetrate into fumarole and cover outside diffuser pipe, avoid diffuser pipe can not being inserted in core pipe and being stretched using entire round tube
Into the problem in fumarole.Casing plays a part of finally to detect, if core pipe can smoothly be inserted in casing and can be assembled to
Core pipe upper end flushes, and can illustrate concentricity within desired deviation range.
Rationally, measurement result is accurate for detection device of the present invention design, high-efficient, more particularly suitable for quantity, arrangement is close
The OC distributor diffuser pipe of collection and the concentricity of fumarole detect, and greatly improve product quality.
