In this embodiment, the controller may be a PLC. In other embodiments, the controller may also be a single-chip microcomputer.
When a leak occurs in the gas tank in the storage chamber 110, the leaked special gas enters the gas discharge pipe 200 along with the gas flow and enters the sampling pipe 210, and is detected by the sensor. At this time, the sensor sends an electric signal to the controller, and the controller controls the display screen to display relevant alarm information after receiving the electric signal so as to prompt relevant personnel to take corresponding countermeasures.
The gas detector is disposed in the exhaust pipe 200, so that the leaked gas is more easily detected by the gas detector at the first time, because the special gas is more than air, and the leaked gas generally flows downwards to be deposited at the bottom of the storage chamber 110. And so set up, even if the ventilation system breaks down, lead to the insufficient or no exhaust volume of the exhaust volume in the cabinet body 100, the special gas that leaks also can flow down to the blast pipe 200 because of self gravity effect to be detected by the gas detector, thereby realize timely, accurate gas detection and warning. In other embodiments, the gas detector may be disposed at the lower or bottom of the storage chamber.
The working principle and the process of the gas distribution cabinet 10 are as follows:
gas tanks containing various types of special gases are stored in the storage chamber 110 of the cabinet 100. External air enters the storage chamber 110 of the cabinet 100 from the air inlet 120, flows through the storage chamber 110, flows from the air outlet 130 to the exhaust duct 200 (see fig. 4 for details, arrows indicate the general flow direction of air), and is then sent to the scrubber. When the special gas in the gas tank leaks, the special gas is mostly heavier than air (i.e. has a density greater than that of air), so that the special gas is generally deposited downwards at the bottom of the storage cavity 110 under the action of self gravity, and the special gas can quickly enter the exhaust pipe 200 from the exhaust port 130 along with the external air under the driving action of the external air entering the storage cavity 110, and finally is conveyed to the washing tower for treatment. Upon entering the exhaust pipe 200, it is detected by the gas detector and displayed and alerted on the display screen to prompt the relevant personnel to take relevant action.
To sum up, the gas distribution cabinet 10 comprises a cabinet body 100 and an exhaust pipe 200, wherein the cabinet body 100 is provided with a storage cavity 110, and an air inlet 120 and an air outlet 130 which are respectively communicated with the storage cavity 110, the air inlet 120 and the air outlet 130 are respectively positioned on two opposite side walls of the cabinet body 100, the air inlet 120 is higher than the air outlet 130, and the exhaust pipe 200 is arranged on the side wall of the cabinet body 100 and is communicated with the air outlet 130 and is used for being communicated with a washing tower through a pipeline. The gas distribution cabinet 10 adopts a top-down ventilation mode, that is, the gas inlet 120 is higher than the gas outlet 130, so that the flow direction of most special gases can be complied, and the leaked and deposited special gases can be rapidly discharged out of the cabinet body 100 through the gas outlet 130, thereby improving the ventilation effect and efficiency. And by arranging the air inlet 120 and the air outlet 130 at opposite sides respectively, the air flow can purge more space inside the cabinet 100, thereby further improving ventilation effect and preventing environmental pollution and safety accidents (such as poisoning, casualties, etc.).
Meanwhile, the air inlet 120 of the cabinet 100 is arranged at the upper part of the cabinet 100, and the air outlet 130 is arranged at the lower part of the cabinet 100, so that the fire-fighting and fire-extinguishing by using CO2, spray water and the like are facilitated. When a fire disaster occurs due to special gas leakage in the cabinet body 100, the flame can move upwards, and in this case, the exhaust port 130 and the exhaust pipe 200 are positioned at the lower part of the cabinet body 100 to better isolate the gas distribution cabinet 10 and the whole ventilation system, so that the fire disaster is prevented, and the safety of the gas distribution cabinet 10 is further improved.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
