Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of disinfection and sterilization of drainage and ventilation systems, and particularly relates to a disinfection and sterilization system and a working method thereof. BACKGROUND

[0002] In the toilet system of a medical system, when the water seal of the toilet is damaged or there is no water seal, pathogenic gas may flow out of the discharge port of the toilet, which is easy to cause the spread of pathogens, and in the toilet system of a medical system, the gas at the end of the ventilation pipe of the toilet is usually not disinfected, and is directly discharged on the roof, so that pathogenic bacteria may overflow with dust and sol, which poses a certain safety hazard to personnel and bedding airing, activities, etc. in the roof of a hospital for preventing and treating various types of infectious diseases. The chlorine dioxide molecule has strong oxidizing power, mainly attacks the electron-rich or electron-donating atomic groups (such as the enzyme and sulfide, nitride containing sulfhydryl in amino acid), forcibly steals electrons, oxidizes and decomposes the amino acid in the microorganism, and makes it lose activity and change properties, so as to achieve the purpose of disinfection and sterilization. At the same time, chlorine dioxide can dehydrate with odor substances (such as H2S, SOH, -NH2, etc.), and make the odor substances rapidly oxidize and transform into other substances, which has effective function. In addition, bacteria, viruses and fungi are all single-cell low-level organisms, and their enzyme systems are distributed on the membrane surface and are easy to be inactivated by the attack of chlorine dioxide. The enzyme systems in human and animal cells are protected by organelles and the protection system, so as to avoid the attack and damage of the enzyme systems. Chlorine dioxide has broad-spectrum, high-efficiency and inactivation effects on microorganisms, but is safe and harmless to humans and animals. Therefore, it is necessary to research a disinfection and sterilization system for the drainage and ventilation system of a medical system and even residential, hotel and other public areas according to the characteristics of chlorine dioxide.

[0036] The medicine concentration online detection feedback system mainly comprises a spraying area medicine concentration online detection device 64, a medicine concentration on-site display and signal transmission device 70 and a controller 71; the spraying area medicine concentration online detection device 64 is arranged inside the ventilation riser 41 and the drainage riser 42, and is electrically connected between the spraying area medicine concentration online detection device 64 and the medicine concentration on-site display and signal transmission device 70 and the controller 71; the controller 71 is connected with the dissolving pool liquid level sensor 10, the dissolving pool liquid level sensor 13, the first spraying area control electromagnetic valve 14, the second spraying area control electromagnetic valve 15, the first medicine adding pressure pump 16, the second medicine adding pressure pump 17 and the dissolving pool water outlet electromagnetic valve 18 in a wired or wireless manner.

[0037] The ultraviolet disinfection device 65 and the ventilation cap 51 are arranged on the top of the ventilation pipe, the top end of the ventilation cap 51 is a cap section, the lower end is a cylindrical section, the ventilation cap 51 is provided with a ventilation hole on the side of the cylindrical section, the ultraviolet disinfection device 65 is arranged on the straight section of the ventilation pipe outside the roof, and below the ventilation cap 51.

[0038] The medicine spraying devices 61 are distributed in the upper, middle and lower parts of the ventilation riser 41 and the top part of the drainage riser 42, the length of the ventilation riser 41 and the drainage riser 42 can be increased or decreased, but they cannot be arranged in other parts of the drainage riser 42 to avoid affecting the drainage efficiency of the drainage pipe.

[0039] When the spraying area medicine concentration online detection device 64 is arranged in the ventilation riser 41, it is arranged on the straight section of the ventilation pipe outside the roof, and can be arranged above the medicine spraying devices 61 and below the ultraviolet disinfection device 65 or above the bottom of the ventilation riser 41 and below the medicine spraying devices 61.

[0041] To enhance the airtightness of the pipeline, the atomizing nozzle 50 of the spray system is pre-sealed and built into the dedicated spray system fitting 43, which is externally connected to the ventilation riser 41 or the drainage riser 42.

[0042] An automatic air vent valve 60 is installed at the top of the agent dosing pipeline 52, and a vent valve 62 is installed at the bottom. The automatic air vent valve 60 is used to automatically release air when the air pressure in the pipeline is too high. The vent valve 62 facilitates the release of disinfectant in the system during system maintenance. The end can be discharged to the floor drain of the well through a hose.

[0043] A method for operating a disinfection, sterilization, and deodorization system includes the following steps:

[0044] Step 1: As Figures 5-8 As shown, in the automatic reagent preparation system, when the controller 71 starts or receives an alarm signal from the solution tank level sensor 13, the manual opening of the screw-cap inlet 11 allows chlorine dioxide tablets to be added into the dissolving tank 1. The controller 71 then initiates the disinfection and deodorization program: the electrically controlled valve at the dissolving tank inlet pipe 6 opens, allowing water from the main inlet pipe 4 to flow into the dissolving tank 1. When the dissolving tank level sensor 10 detects that the water level has reached its maximum, the electrically controlled valve at the dissolving tank inlet pipe 6 automatically closes, and the main inlet pipe 4 stops supplying water to the dissolving tank inlet pipe 6. During a settling time t1, the dissolving tank stirring device 7 operates to increase the dissolution rate. After a running time t2, it automatically shuts off. A high concentration of reagent is formed in solution tank 1. The solenoid valve 18 of the outlet pipe of the dissolving tank is opened, and the high concentration of reagent in solution tank 1 is pumped to solution tank 2. The electric control valve at the inlet pipe 5 of solution tank is opened to allow water to enter solution tank 2. When the solution tank level sensor 13 detects that the solution tank water level has reached its maximum, the electric control valve at the inlet pipe 5 of solution tank is automatically closed, the inlet pipe 4 stops supplying water to the inlet pipe 5 of solution tank, and the water flows from the inlet pipe 5 of solution tank into solution tank 2 to dilute the high concentration of reagent in solution tank 2. The first solution tank stirring device 8 and the second solution tank stirring device 9 operate to accelerate the dilution rate. After the running time t3, they are automatically shut down, and the working concentration of reagent is formed in solution tank 2. Thus, the reagent preparation work is automatically completed.

[0045] Step Two: As Figure 2 , Figure 4As shown, the automatic dosing system is started by the controller 71: when the system is started or the online detection device 64 detects that the concentration of the medicament in the spray area is insufficient for a certain period of time (the time is consistent with the disinfection cycle, for example, the disinfection cycle is twelve hours, and the certain period of time is twelve hours), the first spray area control electromagnetic valve 14 is opened to supply the medicament to the atomizing nozzle 50 in the ventilation riser pipe 41, or the second spray area control electromagnetic valve 15 is opened to supply the medicament to the atomizing nozzle 50 in the drainage riser pipe 42 (both can not be opened at the same time), and the first spray area control electromagnetic valve 14 and the second spray area control electromagnetic valve 15 are automatically started synchronously, and the first medicament dosing pump 16 or the second medicament dosing pump 17 in the pipeline is started synchronously, so that the inside of the ventilation riser pipe 41 and the drainage riser pipe 42 is sprayed and disinfected and deodorized through the medicament dosing pipeline 52 and the medicament spraying device 61. When the online detection device 64 detects that the concentration of the medicament in the ventilation riser pipe 41 and the drainage riser pipe 42 reaches a certain value, the first spray area control electromagnetic valve 14 and the second spray area control electromagnetic valve 15 opened in the foregoing step are closed, and the first medicament dosing pump 16 and the second medicament dosing pump 17 opened in the foregoing step are closed, and thus the automatic medicament dosing work in one area is completed.

[0046] Step three: After the online detection device 64 detects the concentration of the medicament in each area, the concentration of the medicament can be displayed on the screen display of the integrated medicament dissolving tank through the RS425 protocol, and then the data is transmitted to the graphic display connected to the controller 71 through the TCP / IP protocol in the signal transmission device 70, so as to inform the staff of the state of the entire disinfection system. In the online detection feedback system of the medicament concentration, taking the chlorine dioxide effervescent tablets and the chlorine dioxide solution as examples, the online detection device 64 is a chlorine dioxide online concentration tester, which can monitor the concentration of free chlorine dioxide in the ventilation riser pipe 41 and the drainage riser pipe 42 in real time, and feedback the signal to the display connected to the controller 71 in time. When the concentration of the medicament in the ventilation riser pipe 41 and the drainage riser pipe 42 is insufficient and the solution pool 2 does not reach the minimum water level, the system can repeatedly perform step two. When the solution pool 2 reaches the minimum water level and the concentration of the medicament in the ventilation riser pipe 41 and the drainage riser pipe 42 is insufficient, the controller 71 sends a prompt action to the staff, and the staff repeats step one according to the prompt.

[0047] The t2 and t3 are the theoretical residence time t of the medicament, and the theoretical residence time t is:

[0048]

[0049] Wherein: k is the reaction rate constant,

[0050] c0 - concentration of the material at the inlet,

[0051] c i - concentration of the material at the average residence time t,

[0052] The residence time t2 or t3 of each reactor is determined according to the concentration of the reagent in the dissolving tank and the working concentration of the solution;

[0053] The quantitative relative relationship between the reaction vessels of the dissolving tank (1) and the solution tank (2) is c1*V1=

[0054] c2*V2

[0055] Wherein: c1 - the concentration of the reagent in the dissolving tank (1), V1 - the effective volume of the dissolving tank (1), c2 - the concentration of the reagent in the solution tank (2), V2 - the effective volume of the solution tank (2), which is used to deduce the size of the reaction vessels of the dissolving tank (1) and the solution tank (2).

[0056] The specific embodiments are only an explanation of the present application, which is not a limitation of the present application, and those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
