Abstract
The utility model discloses an anti-corrosion protective device for computers of an operation station of a distributed control system, belongs to the technical field of chemical equipment, and is used for anti-corrosion protection of the computers of the operation station of the distributed control system in trichlorosilane production. The anti-corrosion protective device consists of an operation desk, a nitrogen gas source, and a gas pipeline, wherein the operation desk has a hollow sealed structure; the computers of the distributed control system are put in the operation desk; the nitrogen gas source is communicated with the operation desk through the gas pipeline; one side of the operation desk is provided with an exhaust fan; and the gas pipeline connecting the nitrogen gas source and the operation desk is provided with a control valve and a filter. The inert gas is selected for protecting the computers and auxiliary equipment, and prevents external corrosive gas from intruding the computers and auxiliary equipment, so that the computers and the auxiliary equipment cannot be corroded by the corrosive gas, components are prevented from being damaged, the equipment can normally work for a long period, the smooth production is ensured, safe accidents are avoided and the production cost is reduced. The device has the advantages of simple integral structure, safety, convenience for installation and practicability.
Description
Technical field
The utility model relates to the anti-corrosion protection device of Distributed Control System active station computer in a kind of trichlorosilane production, belongs to technical field of chemical.
Background technology
Distributed Control System active station during trichlorosilane is produced is the nucleus equipment of production process of trichlorosilane control, and all technological parameters and interlocked control all show execution at active station in process of production.In process of production, owing to receive the erosion of etchant gas in the environment, computer circuitry in the active station and wiring board are easy to corroded, and want removable parts computer and auxiliary equipment every half a year, have influenced the continuity of producing, and have promoted production cost.Even more serious is, in case active station computer and auxiliary equipment are damaged, not only influences Chemical Manufacture, also can cause and produce and security incident, produces unpredictable consequence.Carry out smoothly for what guarantee to produce, avoid taking place security incident, reduce production costs, be necessary to take effective anticorrosive measure that existing active station is improved.
The utility model content
The utility model technical problem to be solved provides the Distributed Control System active station computer erosion protection system simple in structure, safe, easy to use that a kind of etchant gas that can reduce in the environment corrodes computer equipment.
The technical scheme that solves the problems of the technologies described above is:
A kind of Distributed Control System active station computer anti-corrosion protection device; It is made up of operating desk, nitrogen source of the gas, gas pipeline; Operating desk is the hermetically-sealed construction of hollow; The computer of Distributed Control System control is placed in the operating desk, and the nitrogen source of the gas is connected with operating desk through gas pipeline, and a side of operating desk is equipped with ventilating fan.
Above-mentioned Distributed Control System active station computer anti-corrosion protection device is equipped with control valve and filter on the gas pipeline of said connection nitrogen source of the gas and operating desk.
The usefulness of the utility model is: adopt the Distributed Control System active station computer anti-corrosion protection device of this structure, select airtight protection computer of inert gas and auxiliary equipment for use, stoped external corrosion property gas to be invaded; Make the erosion of computer and servicing unit protect it from corrosion property gas; Prevent the damage of components and parts, equipment can be run well by long period, guarantee carrying out smoothly of production; Avoid taking place security incident, reduce production costs.This device has simple, safe, easy for installation, the practical advantage of overall structure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark is following among the figure: operating desk 1, nitrogen source of the gas 2, control valve 3, filter 4, gas pipeline 5, ventilating fan 6, computer 7.
The specific embodiment
The utility model selects for use inert gas that computer and auxiliary equipment are protected, and has stoped external corrosion property gas to be invaded, and prevents that components and parts from damaging, and guarantees the equipment long-term operation.
Show among the figure that the utility model is made up of operating desk 1, nitrogen source of the gas 2, control valve 3, filter 4, gas pipeline 5 and ventilating fan 6.
Operating desk 1 is the hermetically-sealed construction of hollow, and the computer 7 of Distributed Control System control is placed in the operating desk 1.
Nitrogen source of the gas 2 is connected with operating desk 1 through gas pipeline 5, and gas pipeline 5 adopts the copper pipe of ￠ 10 * 2, and the air inlet of the gas pipeline 5 of nitrogen source of the gas 2 is installed in centre position, operating desk 1 below.
Be connected control valve 3 and filter 4 are installed on the gas pipeline 5 of operating desk 1 one sides, the opposite side of operating desk 1 is equipped with ventilating fan 6, and ventilating fan 6 usefulness screws are fixed on the top of operating desk 1 opposite side, guarantees that gas drains the heat that machine sends.
The utility model is through the nitrogen-sealed replacement aeration, and the heat that the equipment of taking away sends through control valve 3 control throughputs, reaches optimum balance.
