Detailed Description
The invention will be further explained with reference to the drawings.
A ventilation method for a production plant according to the present invention, as shown in fig. 1 and 2, comprises the steps of: s10: detecting the oxygen concentration in the production workshop; s20: and comparing the oxygen concentration with a first preset concentration value, and controlling the ventilation device 30 to ventilate when the oxygen concentration is lower than the preset concentration value until the oxygen concentration reaches a second preset concentration value. Specifically, the ventilation method comprises the following steps: gas detection device 10, control device 20, and ventilation device 30. The gas detection device 10 is used for detecting the oxygen concentration in the production workshop and generating a gas density detection signal; further, the gas detection device 10 is an oxygen concentration sensor, and the oxygen concentration sensor can effectively detect the oxygen concentration in the closed space; a control device 20 electrically connected to the gas detection device 10; a ventilation device 30 electrically connected to the control device 20, and including an exhaust port for exhausting the gas in the production plant to the outside, and a ventilation port for sucking the outdoor air into the production plant; it is worth to be noted that the first preset concentration value is smaller than the second preset concentration value.
The control device 20 is configured to receive the gas density detection signal, compare the gas density detection signal with a first preset concentration value in the control device 20, and when the gas density detection signal is lower than the first preset concentration value, the control device 20 controls the ventilator 30 to ventilate until the gas density detection signal reaches a second preset concentration value. The ventilation method can realize air replacement between a workshop and the outside, thereby ensuring the health of workers in the workshop, and has the advantages of simple structure, convenient installation and low manufacturing cost.
That is, the gas detection device 10 detects the oxygen concentration in the production plant in real time and converts the oxygen concentration into a gas density signal, the control device 20 receives the gas density signal, and when the gas density detection signal is lower than a first preset concentration value, the control device 20 controls the ventilation device 30 to ventilate until the gas density detection signal reaches a second preset concentration value. When the gas density detection signal is higher than the first preset concentration value, the ventilator 30 does not operate.
Further, in the step S10, an oxygen concentration sensor is included. Specifically, the ventilation device 30 is plural; specifically, the ventilation devices 30 are respectively arranged at a plurality of positions of the production workshop and are electrically connected with the control device 20, and when the gas density detection signal is lower than a first preset concentration value, the control device 20 controls the plurality of ventilation devices 30 to perform ventilation simultaneously, so that the ventilation efficiency of the production workshop is improved.
Preferably, in step S20, a filter element is disposed at the air outlet of the ventilation device 30 for filtering large particles of impurities in the gas in the plant. Preferably, the exhaust port is provided with a filter element for filtering large-particle impurities in gas in the workshop, specifically, the filter element is detachably mounted at the exhaust port, and the large-particle impurities in the workshop can be filtered by the filter element, so that pollution to outdoor air is avoided, and the environment is protected; the filter element is detachably arranged at the air outlet, so that the filter element is convenient to detach and replace.
Preferably, in step S10, oxygen concentrations are detected at different heights in the plant. Specifically, the gas detection devices 10 are multiple and are sequentially arranged along the height of the workshop, and the gas detection devices 10 are arranged at different spatial heights of the workshop, so that the gas in the production workshops with different heights can be detected simultaneously, and the detection reliability of the gas detection devices 10 is ensured.
Compared with the prior art, the ventilation method for the production workshop can effectively produce gas in the workshop, improves the air quality of the workshop, and is simple in structure and convenient to install.
