The characteristics of ature of coal is different, the danger that system is accidentally burnt and exploded unavoidably.Wherein detonation factors mainly have the concentration of coal dust, gas
CO contents and the factor such as oxygen content and temperature severe overweight, exist and are exploded by running into open flame source in body mixture.
Coal dust is piled up temperature of long duration and is raised and spontaneous combustion easily occurs, typically with inert gas (CO2、N2) and the fire extinguishing material such as foam, powder enter
Row fire extinguishing.Airduct of the pulverized coal system containing coal dust can typically add anti-riot valve to avoid dust stratification from causing coal dust firing and blast, add
Extinguishing device adds automatic monitoring device, and by investment is limited, the CO detections of some key points can only be abandoned, and result is
Increased the potential safety hazard of production system.

Fig. 3 is the flow chart of detection control.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Illustrated with reference to Fig. 1 and Fig. 2, a kind of coal dust shop safety servicing unit based on sensor detection, including CO detections
Controller, CO detection controllers are used to control the gas sensor of sample gas disposal unit and connection sample gas disposal unit, at sample gas
Reason unit is connected with sampling probe by sampling pipe, and gas sensor is provided with acoustic-optic alarm and linkage, linkage dress
Putting can drive air accumulator to open its deflation valve, and inert gas (CO is housed in air accumulator2、N2), CO detection controllers are also associated with
Temperature sensor.
Wherein, CO detections controller includes control module, communication module, display module and power module, with reference to pid algorithm
And AD conversion, realize detection to the sampling of module, filtering, and to gas sensor and temperature sensor, pressure switch
Detection, the control of gas storage tank valve.Sample gas disposal unit is provided with aspiration pump, sample gas is extracted by sampling pipe, on sampling pipe
Sampling position magnetic valve and blowback position magnetic valve are provided with, and are connected with air water filter and spinner flowmeter.
During the device busy, sampling probe is first arranged on the suitable position of coal mill, Pulverized Coal Bin, dust-precipitator and associated conduit
Put；In the instrument box under the work of aspiration pump, the sample gas of the sample point rough dusting first at sampling probe, via sampling pipe
Into instrument box；Under the work of detection controller；
Then, sampling position magnetic valve in sample gas disposal unit, blowback position magnetic valve work successively, and air water filter will
Gas in pipeline is not changed gas according to the acceptable pressure of analytical instrument, temperature, flow, water content, dustiness
The treatment of composition, removes moisture and small dust, and the sample gas after filtering is passed by triple valve, spinner flowmeter into gas again
It is analyzed in sensor；
Subsequently, as shown in figure 3, CO detects that controller obtains CO concentration and shows and export corresponding simulation letter by detection
Number (4-20mA), CO detection controllers carry out linkage intervention to testing result in real time, and sound and light alarm is sent when transfiniting, and then pass through
Temperature sensor testing equipment internal temperature, and output temperature analog signal (4-20mA), then by CO concentration of analog signal and temperature
Degree analog signal coordinates, and judges whether to be the value that transfinites via detection controller logic, is to open linkage, drives gas storage
Tank valve, discharges inert gas, coordinates the fire extinguishing material such as foam, powder to be put out a fire, while gas cylinder feedback signal is received, otherwise
Continue normal detection.
