Description

A kind of pressurised atomised distributor of self-driving machine

[technical field]

The utility model relates to a kind of pressurised atomised distributor of self-driving machine, which utilizes the gas of institute's in-line Body flows kinetic energy driving vane structure rotation, and rotary motion is the rotary motion of pressurization screw rod by soft-axle transmission structure transmitting, It will be sprayed after liquid neutrality medium pressurization from inlet tube from spray head, form the protection of neutrality liquid medium in inner wall of the pipe Layer, to reduce the corrosion of pipeline where corrosive goods are verified.

[background technique]

In oil refining and chemical plant installations, due to containing corrosive substance in raw material, reacted in order to prevent in following process The corrosion leakage risk of Cheng Zhong, device and equipment, the gas of the liquid injection reaction process usually by a certain amount of with neutrality In phase stock media, play the role of neutralizing the corrosive substance in phase feed medium.Simultaneously higher in corrosion risk Distributor is arranged in position, the inner wall of position pipeline where the liquid of the neutrality of injection is evenly distributed in, in inner wall of the pipe Liquid medium protective layer is formed, to achieve the effect that the perishable position of protection.

And as the research to neutrality injected media deepens continuously, how using least protective agent to reach maximum Protecting effect, low discharge, high concentration protective agent injection mode under, make protective agent efficiently inner wall of the pipe formed protect Layer, the operation energy-saving for device are of great significance to.

However the atomizer of conventional tiny flow quantity atomization distributor (flow is generally between 5~50Kg/h) designs hardly possible It spends larger, spray head aperture must be reduced in order to obtain preferable atomizing effect, realize atomization effect by the way that auxiliary agent is pressurizeed speedup Fruit, and too small spray head aperture is usually blocked by the impurity in auxiliary agent, influences equipment long-term operation.It is infused according to direct branch pipe Enter, atomizing effect is poor, and medium is unrestrained in raindrop shape after inlet tube enters pipeline, in duct bottom aggregation, trickling, injection Liquid medium protective layer adequately cannot be formed in inner wall of the pipe with property medium, etch-proof technique purpose can not be played.

[utility model content]

Described in background technology to solve the problems, such as, the utility model devises a kind of pressurised atomised distribution of self-driving machine Device is rotated using the gas flowing kinetic energy driving vane structure of institute's in-line, and rotary motion is transmitted by soft-axle transmission structure For the rotary motion for being pressurized screw rod, will be sprayed after the liquid neutrality medium pressurization from inlet tube from spray head, in inner wall of the pipe Neutrality liquid medium protective layer is formed, to reduce the corrosion of pipeline where corrosive goods are verified.

To achieve the goals above, the utility model uses following design structure:

A kind of pressurised atomised distributor of self-driving machine, including inlet tube, shell, driving snake, drive shaft bearing, vane Bar, vane main shaft, driving vane, driven axle bearing, pressurization screw rod, atomizer, the shell are divided into running part and pressurization Drive shaft bearing, the vane main shaft and drive shaft bearing are installed in the lower entrances setting aperture of shell running part in part Socket installation with one heart connects vane bar in the front end of the vane main shaft, in the front end of vane bar connection driving wind Cup, in the front end of the rear end of vane main shaft connection driving snake, the rear end connection pressurization screw rod of the driving snake, in institute Driven axle bearing is installed in the outlet setting aperture for stating shell running part, and the pressurization screw rod and driven axle bearing concentric locking collar connect peace Dress is connected with inlet tube on the top of the shell compression portion, and the pressurization screw rod is located at the inner cavity of shell compression portion, institute The outlet connection atomizer for stating shell compression portion, forms the pressurised atomised distributor of self-driving machine.

The driving vane quantity is odd number, along using vane main shaft as the circumference uniform distribution of axis.

The high speed rotation of the vane main shaft is transferred to pressurization screw rod by driving snake.

There is screw thread shape runner on the pressurization screw rod, the liquid medium from inlet tube can be pressurized after accelerating and be sprayed from atomization Head sprays, and liquid medium forms wide-angle spray cone shape from after atomizer ejection.

Wherein the inlet tube carrys out liquid pipe line with outside and connect, and the type of attachment of screw thread or flange can be used.This reality simultaneously With it is novel can integral installation to place pipeline center position, any injecting position, any pouring agent flow quantity can be used.

Due to using above-mentioned design structure, the utility model is had the advantages that

1, overall structure is simple, and all parts are easy to process, convenient for whole assembly.

2, pneumatic structure is compact, and drive efficiency is high.

3, dispersion effect is good, the neutrality medium of injection efficiently and uniformly can be scattered to inner wall of the pipe, protective agent makes Use ultrahigh in efficiency.

4, wide adaptation range, when the variation range of decanting point pouring agent flow quantity is larger, the utility model can have well Using effect.
