Embodiment Construction

[0024] An ultraviolet disinfection device is installed on the drainage pipe. The ultraviolet disinfection device has the function of structural optimization, enhanced contact intensity of exhaust and ultraviolet disinfection, can effectively disinfect the exhaust, and can monitor the intensity of ultraviolet disinfection through a sensor.

[0025] Such as figure 1 As shown, the exhaust gas in the drainage extension vent pipe 6 enters the housing 1 of the disinfection device. The housing 1 of the disinfection device is provided with a partition 3, which divides the disinfection device into a number of connected spaces to increase the amount of disinfection. For the flow distance of the gas, an ultraviolet disinfection tube 2 is set in each space. The exhaust gas passes through the partition 3 and then exits to the drainage extension vent pipe 6.

[0026] The partition 3 of the present invention is used to increase the exhaust radiation disinfection time of the exhaust in the housin...

Abstract

The invention belongs to the public health technical field of sewage and waste water drainage pipe systems in building water supply and drainage, and relates to an ultraviolet sterilizing device for drainage ventilating pipes. The technical solution is: a disinfection device is arranged on the drainage extension vent pipe, and the inner cross section of the shell of the disinfection device is larger than the pipe inner diameter area of ​​the drainage extension vent pipe. The shell of the disinfection device is provided with a partition, which divides the disinfection device into several connected spaces and increases the flow distance of the gas to be sterilized. An ultraviolet disinfection tube is arranged in each space. The device has the function of high-efficiency sterilization, increases the irradiation residence time of the gas in the drain pipe within the same volume, increases the irradiation amount of the gas in the drain pipe in the device, and also has the function of sensing the irradiance of the Internet of Things.

Description

Technical field [0001] The invention belongs to the public health technical field of sewage and wastewater drainage pipeline systems in building water supply and drainage, and particularly relates to building drainage pipeline systems. Background technique [0002] In the building drainage system, ventilation and drainage are equally important. Sewage or wastewater needs to be exchanged with the air in the atmosphere to balance the pressure when the pipe system is exhausted. For the ventilation and disinfection of sewage and waste water pipe drainage in infectious departments in medical institutions, it is necessary to strengthen the public health safety of the air environment of medical institutions. [0003] The drainage design of conventional medical institutions requires disinfection of their domestic drainage (sewage and wastewater), especially hospital sewage must be disinfected, and the gas discharged from the sewage drainage pipe is generally not disinfected. In fact, the ...
