The solubility in water is very low, but it is easily soluble in ammonia water. The air mixed explosion limit is 12.5% to 74%. After entering the human body, carbon monoxide will combine with hemoglobin in the blood, which will prevent hemoglobin from combining with oxygen, causing hypoxia in the body tissues and leading to suffocation and death. During the entire coal powder preparation process, it is necessary to monitor the carbon monoxide in the powder selector, the inlet and outlet of the coal powder bin dust collector, and the raw coal bin in real time to prevent accidents and ensure normal production.
[0003] The existing carbon monoxide concentration detection is carried out through a carbon monoxide analyzer. The carbon monoxide analyzer is equipped with either a coarse filter or a fine filter. The coarse filter can only filter coarse particles but not fine particles, which will interfere with the determination of carbon monoxide; the fine filter can filter both coarse and fine particles, but the filter is easily clogged and requires frequent maintenance, and the overall practicality is poor.

[0006] Preferably, four footings are installed at the four corners of the bottom of the detection box in a rectangular array. By providing the four footings, the detection box can be stably supported.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] When the utility model is used, the gas in the powder selector, the coal powder bin dust collector and the raw coal bin enters the purification chamber from the air inlet pipe. When the gas enters the air inlet pipe, it will be filtered through the filter to remove coarse particles. The water pump works to send external water source into the spray pipe, and sprays out from the nozzle to purify the gas and remove dust and fine particles. The purified gas enters the detection chamber from the air outlet pipe one and is sucked away from the air outlet pipe two by the air pump. During the flow of the gas in the detection chamber, the carbon monoxide detector will detect the carbon monoxide concentration in the gas. After the detection is completed, the vibration motor will work to vibrate the dust on the filter into the dust storage barrel. It only needs to clean the dust in the dust storage barrel regularly, so as to filter out coarse and fine particles at the same time without clogging and without maintenance in the later stage, thereby improving the practicability of the device.
