Abstract

PURPOSE:To remove floating substances in unmanned way which adhere to the surface of an ultraviolet ray generating tube by jetting air from a gas spraying apparatus every prescribed time to cause turbulence in a liquid to be sterilized and separating and removing the adhering substances from the ultraviolet generating tube. CONSTITUTION:One end of a quartz sleeve 16 containing an ultraviolet ray generating tube 2 is attached by a holding sleeve 14 to a vertical pipe 11 for attaching ultraviolet ray generating tube. The other end is elastically supported through an O-ring by a holding sleeve 17 which is forked into two and attached to a vertical pipe 12. Jetting air to be sprayed is carried out based on the pollution of the surface of the quartz sleeve 16 containing the ultraviolet ray generating tube 2. That is, an ultraviolet ray detecting sensor which can measure the intensity of ultraviolet ray is installed at the position apart from the ultraviolet ray generating tube 2 by 1cm and when the ultraviolet absorptivity of the liquid to be sterilized lowers, air in a gas spraying apparatus is jetted out based on the signals from the sensor.

In order to solve the above-mentioned problems, the ultraviolet disinfection apparatus according to the present invention has an ultraviolet ray generating tube for inactivating microorganisms (harmful bacteria such as pathogenic bacteria) to be disinfected in a disinfection chamber. It is placed in a liquid and an air diffuser is installed below the ultraviolet ray generating tube and below the disinfection chamber. From the air diffuser, air is jetted every lapse of a fixed time to make the liquid to be disinfected turbulent. Due to the turbulent flow of the liquid to be disinfected, the deposits on the ultraviolet ray generating tube are separated and removed. Further, in order to perform air injection from the air diffuser unattended, a plurality of air injection ports attached to the upper portion of the air diffuser automatically open and close.

The air diffuser comprises an air diffuser, an air diffusing chamber, a partition for partitioning the air diffusing chamber, and an air injection port lid, and the air injection port lid is always closed so that the lid moves only when air is diffused and air is blown. It is preferable that it has a structure for jetting.

The air injection port lid can be moved up and down and is normally closed, but it may have a structure that floats up only when air is diffused. Further, in order to reduce the cost, it is desirable that the air diffuser has a compact structure that can be manufactured in a factory, and that the air diffuser can be attached in a cartridge system below the ultraviolet ray generating tube. Further, the air diffuser may be attached not to the entire lower surface of the ultraviolet ray generating tube but to a part thereof, and the position may be moved periodically.

The function of stirring the liquid around the ultraviolet ray generating tube in order to remove the deposits on the ultraviolet ray generating tube will be described.
The air diffuser of the air diffuser is installed horizontally in the air diffuser in a direction parallel to the ultraviolet ray generating tube. Install the air outlet nozzle on top of the diffuser. At least one or more outlet nozzles are attached to each space in which the diffusion chamber is partitioned by the partition wall.

The blast air is supplied from a compressor provided outside the disinfection chamber. It may be supplied by branching from another work air pipe. The blast air is supplied to the air diffusing chamber after a certain period of time. This is because it takes a certain amount of time for floating substances to adhere to the ultraviolet ray generation tube. However, the liquid to be disinfected around the ultraviolet ray generating tube should be stirred before a large amount of the deposit is deposited. This is so that the attached matter can be easily separated and removed.

When compressed air is supplied to the air diffuser from the air diffuser, the compressed air accumulates in the air diffuser because the air injection port lid provided on the upper part of the air diffuser is closed. The air pressure in the air diffusing chamber rises, the spout lid opens upward, and air is jetted into the disinfection chamber. If the air supply to the air diffuser is stopped after a certain period of time, the injection port cover is closed due to the weight of the injection port cover. Therefore, the action of ultraviolet rays is not hindered by aeration.

If the air supply to the air diffusing chamber is automatically turned on / off, the above operation is repeated unattended. A plurality of partition walls are provided in the air diffusing chamber at right angles to the flow of the liquid to be disinfected. The reason why the partition wall is provided in the air diffusing chamber is to prevent the liquid in the air diffusing chamber from becoming a short-circuit flow without being disinfected.
