Abstract
The utility model relates to an automatic coal gas leakage detection, alarm and ventilation device used in a semi-closed space, which consists of a host computer 1, a sensor 5, a combined aural and visual alarm 6, a fan motor 3 and a chimney 2. The fan motor 3 is installed outside the semi-closed space. An air pipe 4 is connected with the fan motor 3 and arranged in the semi-close space. The air pipe 4 is connected with an air suction hood 7. The sensor 5 and the combined aural and visual alarm 6 are installed beside the air suction hood 7. The sensor 5, the combined aural and visual alarm 6 and the fan motor 3 are respectively connected with the host computer 1. The utility model has the advantages that the coal gas detection device and the automatic ventilation device are integrated, the safety performance of the device is improved and the carbon monoxide poisoning accidents are reduced.
Description
Technical field
The utility model relate to a kind of in the semi-hermetic space gas leak detection alarm and can be immediately air exhausting device automatically.
Background technology
Coal gas is the important energy source of industrial production and daily life, along with rapid development of economy, the use of coal gas more and more widely, there is leakage in various degree in coal gas in processes such as production, storage, conveying, the gas safety accident happens occasionally.Therefore, reduce the work position gas concentration, guard against gas poisoning and fire incident be the emphasis of enterprise security manager work.Coal gas is the carbon monoxide colorless and odorless, is easy to burning, if carbon monoxide content reaches in the air, the people is poisoned in short-term at 0.05% o'clock.The gas leak detector that uses has polytype at present, generally all has gas leak detection alarm function.But for the working space of semi-hermetic, after warning device was reported to the police, because it is not smooth to ventilate, the coal gas of leakage can not in time be discharged, and caused the poisoning personnel can not obtain relief in time, caused casualties.
Summary of the invention
The purpose of this utility model is the problem that exists at present gas alarm device, and the device of a kind of coal gas detection alarm simultaneously air draft is provided,
Technical solution of the present utility model is: coal gas detection alarm air exhausting device, form by computer control main frame, sensor, audible-visual annunciator, blower motor, chimney, chimney is connected with blower motor, blower motor is installed in outside the semi-hermetic space, airduct is connected with blower motor, and airduct is located in the semi-hermetic space, connects suspended hood on the airduct, at suspended hood next door sensor installation and audible-visual annunciator, sensor, audible-visual annunciator, blower motor are connected with the computer control main frame respectively.
Operation principle: when gas leak takes place in the semi-hermetic space, this space then becomes the gas leak zone, detect the gas concentration of leakage gas by a plurality of coal gas monitoring sensors that are installed in this zone, convert 4～20mA normalized current signal to through transmitter and be sent to the computer control main frame, main frame carries out on-line monitoring to each measuring point, shows the measuring point concentration value in real time.As gas leak, and concentration reaches first order when setting value, is installed in on-the-spot audible-visual annunciator and begins to report to the police, and reminds the field operation personnel to take care.When leakage gas concentration continuation rising, when reaching second level setting value, the secondary sound and light alarm; Simultaneously, start blower motor work automatically, leakage gas causes chimney by exhaust duct and discharges, and reduces this zone gas concentration.When the measuring point gas concentration is lower than setting value, blower motor quits work automatically, and alarm stops to report to the police.
The beneficial effects of the utility model are: coal gas monitoring and air exhausting device are automatically combined, and perfect device ' makes the timely emptying of coal gas of leakage, has reduced the generation of gas poisoning.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Coal gas detection alarm air exhausting device, form by computer control main frame 1, sensor 5, audible-visual annunciator 6, blower motor 3, chimney 2, chimney 2 is connected with blower motor 3, blower motor 3 is installed in outside the semi-hermetic space, airduct 4 is connected with blower motor 3, and airduct 4 is located in the semi-hermetic space, connects suspended hood 7 on the airduct 4, at suspended hood 7 next door sensor installations 5 and audible-visual annunciator 6, sensor 5, audible-visual annunciator 6, blower motor 3 are connected with computer control main frame 1 respectively.
Operation principle: the gas concentration that detects leakage gas by a plurality of coal gas monitoring sensors 5 that are installed in this zone, convert 4～20mA normalized current signal to through transmitter and be sent to computer control main frame 1,1 pair of each measuring point of main frame carries out on-line monitoring, shows the measuring point concentration value in real time.As gas leak, and concentration reaches first order when setting value, is installed in on-the-spot audible-visual annunciator 6 and begins to report to the police, and reminds the field operation personnel to take care.When leakage gas concentration continuation rising, when reaching second level setting value, the secondary sound and light alarm; Simultaneously, start blower motor 3 work automatically, leakage gas causes chimney 2 by airduct 4 and discharges, and reduces this zone gas concentration.When the measuring point gas concentration is lower than setting value, blower motor 3 quits work automatically, and audible-visual annunciator 6 stops to report to the police.
