The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

As shown in Figures 1-4, this utility model is a centralized vaporization and intelligent concentration control disinfection system, including a host 1, a gas transmission branch 2, and the upper end of the host 1 is equipped with a gas transmission branch 2;

The gas transmission branch 2 includes a connecting hose 201, a gas transmission pipeline 202, and a micro-hole nozzle 203;

The host 1 includes a solvent purification box 101, a host housing 102 is sleeved around the outside of the solvent purification box 101, a fan 1010 is installed on the top of the host housing 102, and a connecting hose 201 is connected to the output end of the fan 1010. The connecting hose 201 is far away from the host housing. One end of 102 is horizontally sleeved and connected with a gas pipeline 202. The upper end of the gas pipeline 202 is installed and fixed with multiple sets of micro-hole nozzles. An air pump 104 is installed and fixedly connected to the air hole 103, a gas pipe 105 is installed at the bottom of the air pump 104, and a vaporization plate 106 is fixedly connected to the bottom of the air pipe 105. The air pump 104 is connected and fixed through the air pipe 105 and the vaporization plate 106. 107. A concentration display 108 is embedded on the surface of the host casing 102 above the water injection port 107, and a solvent concentration sensor 109 is provided at the bottom of the inner cavity of the solvent purification tank 101.

Among them, the total area of all the micro-orifice nozzles 203 on the pipeline is the same as the area of the fan 1010, the connecting hose 201 is connected to the gas pipeline 202 through the connecting pipe 1011, and the gas pipeline 202 is provided with micro-orifice nozzles at intervals. 203, and evenly distributed on the outer wall of the gas pipeline 202, the solvent concentration sensor 109 is a photodiode sensor with a fast response speed.

A specific application of this embodiment is: when a disinfection system with centralized vaporization and intelligent concentration control is in use, a disinfectant (such as chlorine dioxide) is concentratedly vaporized in a disinfection solvent purification box 101, and the disinfection gas volatilized It is extracted from the upper space of the solvent purification box 101 by the fan 1010, and is transported through the pre-laid gas pipeline 202. There is a micro-hole nozzle 203 at every interval on the gas pipeline 202, in order to let all the micro-hole nozzles come out. 203 can have the same air output. The total area of all the micro-hole nozzles 203 on the pipeline is similar to the area of the fan 1010, and it shows the characteristic that the farther away from the solvent purification tank 101, the larger the aperture;

Secure a specific solvent concentration sensor 109 in the solution. The concentration detection method is to detect the light transmittance of the solution. For example, a high-concentration chlorine dioxide solution appears dark yellow. As the concentration of chlorine dioxide in the solution decreases, The color of the chlorine dioxide solution gradually changes from dark yellow to light yellow until it is completely transparent, that is, the higher the concentration of the chlorine dioxide solution, the darker the color, the lower the light transmittance, on the contrary, the higher the light transmittance, which is about a 10 cm pipe At the two ends, a device that can generate a light source and a sensor that are sensitive to light are respectively placed. Because the chlorine dioxide solution is yellow, the light source uses light with a wavelength between 450 and 480 nm to illuminate. The light at this wavelength is easy to be Yellow absorption can achieve a better detection effect. The photosensitive sensor adopts a photodiode, which has a fast response speed and can filter the interference of ambient light, and the signal output changes linearly with the change of light intensity, which can achieve a more accurate detection effect. When the pipe sinks into the solution, the pipe will be filled with chlorine dioxide solution. One end of the pipe will be irradiated with a light source with constant light intensity. With the difference in light absorption capacity of the chlorine dioxide solution of different concentrations, the photosensitive sensor can output the same as the concentration of chlorine dioxide. The positively correlated analog voltage can be calculated by the internal program of the single-chip microcomputer to determine the chlorine dioxide content in the solution, and the concentration of the chlorine dioxide solution can be displayed on the concentration display 108 in real time, and the fan 1010 can be adjusted according to the concentration. Rotation speed and gas output of vaporization plate 106;

In order to maintain the concentration of the disinfectant (such as chlorine dioxide) in the space at an appropriate level, it is not only necessary to pass through the gas pipeline 202, but also to be able to effectively control the volatilization intensity of the disinfectant solution. Install a fan 1010 at the air outlet of the solvent purification box 101 and place a vaporization disk 106 at the bottom of the solvent purification box 101. The vaporization disk 106 absorbs the outside air through the air pump 104, scatters the air stones, enters the solution, and the scattered air forms countless in the solution. Small bubbles, increase the volatilization area of the solution, change the volatilization capacity of the solution, strengthen and control the volatilization capacity of the disinfectant (such as chlorine dioxide) solution by adjusting the power of the vaporization plate, 106, when the disinfectant is at a high concentration, the air pump 104 stops or When running at low power, the fan 1010 also runs at low power; as the concentration of the disinfectant decreases, the power of the vaporization plate 106 and the fan 1010 increase, until the concentration of the disinfectant is too low, the machine stops and waits for the disinfectant to be replaced.
