Abstract
The invention relates to an anticorrosion cabinet used for isolating electronic equipment from coal gas. A cabinet body is formed by a front panel, a rear panel, a left panel, a right panel, a top plate and a bottom plate in a defined mode, sealing rubber mats are arranged on the connecting edges, and therefore the cabinet body is sealed completely. An air inlet hole is formed in the center of the bottom plate of the anticorrosion cabinet, cable holes with the ventilation capacity are formed in the rear panel, and the section area of the air inlet hole is slightly larger than the ventilation area of the cable holes. The right amount of compressed air is introduced from the air inlet hole, the flow can ensure that the whole anticorrosion cabinet is filled with the compressed air, and positive pressure is formed in the cabinet. The front panel is made of armorplate glass and used for observing operation signal indicator lamps in the electronic equipment in the cabinet. Air flowability in the cabinet body is high, so that heat of the electronic equipment is dissipated easily; due to the positive pressure kept in the cabinet body, air mixed with the coal gas can be effectively prevented from flowing into the anticorrosion cabinet, and the electronic equipment is effectively isolated from the coal gas.

Embodiment
In order to understand technology contents of the present invention in detail, will be described as follows by embodiment and accompanying drawing.
The object of the invention is to set up a space, electronic equipment is placed wherein, make the gas isolation outside its effective and space, thus reach the effect preventing gas corrosion.And this difficult point is wherein exactly how to prevent the coal gas outside space from entering space, if by space sealing, inherently because cannot effectively dispel the heat when not having air flow and cause electronic equipment to run in space, have influence on the stable operation of electronic equipment equally.So will there be certain sealing in this space, and there is again free air-flow to move, more can effectively the air exclusion being mixed with coal gas outside space be come.So just can guarantee the stable operation of this space inner electronic equipment.
As Figure 1-3, the master for the anticorrosion cabinet by electronic equipment and gas isolation of the present invention depending on, overlook, a left side looks schematic diagram.The anticorrosion cabinet of the present embodiment comprises the cabinet 10 surrounded by left panel 4, right panel 5, top board 6, base plate 7, front plate 8 and rear board 9, has fresh air inlet 2 in the central authorities of base plate, and below, the down either side of plate 9 has two cable aperture 1 respectively.Another embodiment also can arrange fresh air inlet 2 again immediately below front plate 8, certainly also can arrange fresh air inlet 2 on other plates.Preferred fresh air inlet 2 only arranges 1, certainly also can arrange more than 2 or 2.Described fresh air inlet 2 introduces appropriate compressed air, and cable is through leaving space after described cable aperture 1 for ventilating.Other embodiment can set out air holes separately, and at this moment cable aperture 1 is preferably only for running through cable, is just sealed by cable aperture 1 after cable laying.Certainly also can coexist with the cable aperture 1 with air-out function by exhaust vent, but total cross-sectional area that condition is fresh air inlet 2 is greater than the air-out area that exhaust vent cross section and cable aperture 1 aeration portion are formed jointly, certain hole arranges too many calculating draught area and arranges installation and all bothers, strengthen cost, therefore preferably cable aperture 1 is the mode of exhaust vent, not only can save cost, also effectively can ensure sealing.
Customize one according to the volume placing electronic equipment and be about greater than electronic equipment cumulative volume 3-12 doubly, preferably 10 times and there is the anticorrosion cabinet of better sealing, and the front plate 8 of anticorrosion cabinet is that toughened glass cast, be mainly used in the run signal indicator light observing cabinet inner electronic equipment.Left panel 4, right panel 5, top board 6 and rear board 9 are all aluminium alloy panel, and aluminium alloy panel quality is light, good rigidly, corrosion-resistant, durable in use, have good isolated and antisepsis to coal gas.Described base plate 7 is ground, can be floor tile, serves as base plate 7 to reduce the materials of anticorrosion cabinet by ground.The thickness of described armorplate glass is 4mm, and the thickness of described aluminium alloy panel is 3mm.
In order to ensure the circulation of gas in anticorrosion cabinet, the compressed air fresh air inlet 2 that a radius is 40mm is configured with in the central authorities of cabinet inner bottom plating 7, be provided with in anticorrosion cabinet both sides simultaneously and place cable connection and two cable aperture 1 possessing ventilation function, radius is all 40mm, owing to having certain cable connection in cable aperture 1, through accurately measuring, 60% of two perforate sectional areas shared by cable connection, can be calculated thus:
S
cable aperture=2S
fresh air inlet
S
ventilate=S
cable aperture× 40%
S
ventilate=2 × S
fresh air inlet× 40%=0.8S
fresh air inlet<S
fresh air inlet
So draught area part is slightly less than the area of fresh air inlet, create condition for keeping being in barotropic state in cabinet.
Compressed air adopts the on-the-spot instrument wind provided, and dry and temperature is at about 20 DEG C, and compressed air pressure is more than 0.5Mpa, and be greater than atmospheric pressure under operating mode, compressed air flow velocity is 5m3/h simultaneously, and anticorrosion cabinet amasss as 2m
3, and fresh air inlet sectional area is slightly larger than draught area, comprehensive above condition, pressure-fired is defined in anticorrosion cabinet, and ensure that the circulation of air, while effectively having completely cut off the outside air containing coal gas, also for the electronic equipment in cabinet creates good running environment.
Anticorrosion cabinet detail specifications size is as follows:
The volume of separate unit electronic equipment main frame 3 is 0.4 × 0.18 × 0.42=0.03m
3, and in order to ensure that heat radiation between main frame 3 and attendant safeguard to possess enough operating spaces, so the interval between every platform main frame 3 is preferably 0.2m, be 0.35m with the difference height on cabinet top, be 0.35 meter with cabinet front and back side spacing summation.If place 6 main frames 3, then the length of putting of main frame 3 is 6 × 0.18+7 × 0.2=2.48m, thus anticorrosion cabinet be sized to length: 2.5m, wide 1.0m, high 0.8m.
The anticorrosion cabinet of isolated coal gas of the present invention extremely effectively makes the gas isolation outside electronic equipment and cabinet, positive pressure energy is kept effectively to prevent coal gas from flowing in cabinet in cabinet, can effectively completely cut off the air being mixed with coal gas, reach antiseptic effect, and there is in cabinet the better air flow property of air quality, be conducive to the heat radiation of electronic equipment; The stable operation of control system electronic equipment is ensure that with extremely low cost.Greatly reduce the consumption of electronic equipment standby redundancy, changed once to extend by original every three months and most within 2 years, change once.Ensure that the stability of control system in addition, thus ensure that the safe and stable operation of production.
Through the compressed air air quantity calculated, tolerance will be economized on to greatest extent, and reduce costs, and the vibration influence avoiding tolerance excessive caused is to the operation of electronic equipment.
