Abstract

The utility model discloses an additive injection device which is composed of an injection nozzle cylinder (1), a sealing plate (2), an oil and gas pipeline (3), a reinforcement pipe connector (4) and a flange (5). The additive injection device is characterized in that the injection nozzle cylinder (1) is inserted in the oil and gas pipeline (3), and the sealing plate (2) is located at the bottom of the injection nozzle cylinder (1) so as to overcome the defects that an additive in the prior art is uneven in injection and poor in effect.

Description

A kind of additive injection device
Technical field
The utility model relates to a kind of injection apparatus, particularly a kind of additive injection device.
Background technique
Corrosion is the important hidden danger that jeopardizes oil refining apparatus safety and steady operation, and it can cause equipment leakage or inefficacy, can cause accidents such as device shut-down and fire, blast when serious, therefore need take certain anti-corrosion measure to slow down or control the generation of corroding.The corrosion control at oil refining apparatus low temperature position is anticorrosion based on technology, and material antiseptic is auxilliary; Corrosion inhibitor is because to have a cost low, simple to operate, and instant effect, and be fit to characteristics such as long-term use is a kind of economy, technology anti-corrosion measure effective and commonly used.
The anticorrosion many additives of interpolation that need of petrochemical plant, as: preservative and corrosion inhibitor, the used low temperature corrosion inhibitor of petrochemical plant is mainly based on filming corrosion inhibitor, and corrosion inhibitor the quality of metal erosion control effect at the good and bad direct relation of steel surface film-formation result.In general; corrosion inhibitor is relevant with corrosion inhibitor performance, corrosion inhibitor adding amount and filling technology at the film-formation result of steel surface; and being corrosion inhibitor, injection nozzle adds a key equipment in the water-injecting technological system; corrosion inhibitor is delivered to the injection nozzle place after pressurizeing through high-pressure service pump; be ejected in the interior profit of pipeline; the corrosion inhibitor drop is distributed to more rapidly in the profit, and the internal surface with pipeline, equipment contacts then, is adsorbed on the metal surface and forms protective film.The key problem in technology of the technology of therefore annotating is injection nozzle, and its quality of injecting effect determines the protection effect of corrosion inhibitor.
The device that prior art is injected preservative and corrosion inhibitor is the main line that preservative and corrosion inhibitor ascending pipe is inserted into working fluid mostly, perhaps just the outlet port of preservative and corrosion inhibitor ascending pipe curves several curved youngsters, make the injection of its ascending pipe more even, but it does not pass through the calculating of fluid mechanics and spray angle, can not effectively be injected in additive in the working fluid, the anticorrosion corrosion mitigating effect of preservative and corrosion inhibitor is not given full play of, preservative and corrosion inhibitor have been wasted, anticorrosion and inhibition weak effect.
The model utility content
The purpose of this utility model just provides a kind of additive injection device, and is inhomogeneous to overcome the prior art additive injection, the defective of weak effect.
A kind of additive injection device of the utility model is made up of injection nozzle cylindrical shell 1, shrouding 2, oil-gas pipeline 3, reinforcement tube joint 4 and flange 5, is characterised in that: injection nozzle cylindrical shell 1 is inserted in the oil-gas pipeline 3, and shrouding 2 is positioned at injection nozzle cylindrical shell 1 bottom.
Described injection nozzle cylindrical shell 1 is cylinder, preferred cylindrical body.
Described injection nozzle cylindrical shell 1 is inserted in the oil-gas pipeline 3 by reinforcement tube joint 4 and flange 5.
Described injection nozzle cylindrical shell 1 is provided with 1~5 circular port 6, the circular port diameter is 1/8~1/3 of injection nozzle cylindrical shell 1 cylinder pipeline outer tube diameter, and the circular port 6 hole hearts of the most close shrouding 2 and the distance of shrouding 2 are injection nozzle cylindrical shell 1 cylinder pipeline outer tube diameter 1~2.Heart distance in hole is 0.5~1.5 times of injection nozzle cylindrical shell, 1 cylinder pipeline outer tube diameter between the circular port 6.
The perforate direction of described circular port 6 is identical with flow direction in the oil-gas pipeline 3.
Reinforcement tube joint 4 one ends are connected with oil-gas pipeline 3, preferred weld, and reinforcement tube joint 4 the other ends are connected the other end and are connected preferred weld with flange 5 with oil-gas pipeline 3.
Described oil-gas pipeline 3 is being installed the straight tube that injection nozzle cylindrical shell 1 installation place has 2~4m or 6~8 times of oil-gas pipeline 3 outer tube diameters at least.
Compared with prior art: a kind of additive injection device of the utility model has simple in structure, reliable performance, advantage such as easy to use.
A kind of additive injection device of the utility model is distributed to additive rapidly in the oil gas of pipeline, makes corrosion inhibitor form effective protective film in the metal surface, better plays anticorrosion corrosion inhibition.
