[0013] Figure 1 It is a schematic structural diagram of an embodiment of the present utility model; Specific implementation manner
[0014] Next, the present utility model will be further described in conjunction with the accompanying drawings.
[0015] An industrial SO2 gas content detection device includes a spray tower and an atomizing spray structure; the spray tower includes an absorption chamber and a water accumulation chamber arranged up and down, a conductivity meter is installed on the bottom pipeline of the water accumulation chamber, and the conductivity meter is connected to an alarm through a host computer;
[0016] The bottom of the absorption chamber is provided with an air inlet pipe, and the top is provided with an air outlet; the atomizing spray structure includes a fan-shaped atomizing nozzle and a water supply pipe. One end of the water supply pipe is connected to a water source, and the other end extends into the absorption chamber and is provided with a fan-shaped atomizing nozzle for forming a water atomization environment in the absorption chamber.
[0017] Further, the spray water introduced into the water supply pipe is deionized water.
[0018] Further, an electric control valve is provided on the air inlet pipe, and the electric control valve is electrically connected to the host computer.
[0019] Further, a transparent window is provided on the side wall of the absorption chamber opposite to the fan-shaped atomizing nozzle.
[0020] Referring to Figure 1 , in this embodiment, the gas discharged from the three-stage absorption tower enters the atomizing spray absorption device. The spray water is deionized water. The gas with a conductivity ≤ 5 μs / cm enters from the bottom of the absorption device. The deionized water sprays through the fan-shaped atomizing nozzle to absorb SO2 in the gas. The conductivity of the deionized water after absorbing SO2 increases accordingly. By actually detecting the conductivity of the absorption liquid after spraying, the linear relationship between the conductivity and the inlet sulfur dioxide content is obtained, and the absorption operation condition of the SO2 spray tower can be reflected.
[0021] Through the connection between the conductivity meter and the host computer, not only can the content of sulfur dioxide be monitored manually, but also the combustion amount of sulfur can be reduced in time through the electronic control system (the conductivity meter as the sensor, the host computer as the controller, and the alarm and the electric control valve on the air inlet pipe as the actuators), avoiding sulfur waste.
