Description
Technical field
The utility model relates to plumbing, sewage, middle water treatment field, particularly a kind of ultraviolet sterilizer.
Background technology
Ultraviolet is the part of electromagnetic spectrum, and wavelength is between 100～400nm, and the germicidal wavelength scope is mainly between 200-300nm.UV-light can't reach sterilisation purpose by reproduction by the hereditary material DNA of break virus, bacterium and other microorganism thereby it is lost activity.The sterilisation effect of UV disinfection system is relevant with uv dosage, is directly proportional with ultraviolet light intensity, time shutter.Microorganism is not reproducible breeding in human body, will natural death or eliminated by immune function of human body, thus can not cause disease infection to propagate.Disinfection by ultraviolet light is a kind of physical disinfection method, without any need for chemical substance, can not produce chemical residual material and chemical by-product, is a kind of disinfection technology of safe, healthy, environmental protection.At present, the disinfection by ultraviolet light technology is widely used in fields such as plumbing sterilization, purifying air.
Present stage, for not with the ultraviolet sterilizer of automatic cleaning function, basic comprising can be divided into electrical control system, reaction two parts.For simplified manufacturing technique and reduce cost, all fluorescent tubes that sterilizer is supporting and quartz socket tube are uniformly distributed in shared single cavity.
Practical application effect for many years shows that this many tubes adopt the design of the single cavity of common can bring following deficiency and negative impact:
(1) for ultraviolet sterilizer, one of key element of design is will guarantee that the uitraviolet intensity of any point all can meet in the cavity to reach the desired minimum uitraviolet intensity of disinfection standard.The design of traditional uv reactor of the shared same single cavity of many tubes, for reducing cavity cost and difficulty of processing, manufacturers adopts the standard pipe fitting to process substantially.Because of the increase and decrease of cavity pipe diameter is to have the level that has of industry standard to change, the diameter of standard pipe fitting often is not the desired gauge of reactor cavity.Therefore cause the un-reasonable phenomenon of " even adopt same model fluorescent tube, the fluorescent tube width between centers in the sterilizer of different size is not of uniform size ".
(2) the circular cavity section is adopted in the design of traditional uv reactor of the shared same single cavity of many tubes usually, can not accomplish the uniform distribution of distance between all fluorescent tubes.Therefore, the uitraviolet intensity difference of reactor each point is very big, causes the low sharp utility ratio of UV-light energy, does not meet the aim of " energy-conserving and environment-protective ".
(3) mode of the shared same single cavity of many tubes causes to holding all fluorescent tubes and has to increase cavity diameter, causes the flow rate of water flow difference of cavity cross-section each point to increase thus, and water body very easily causes the waterpower short circuit in cavity.For the less cavity of larger amt fluorescent tube or intake-outlet distance has been installed, the waterpower short circuit is inevitable especially.
(4) generally speaking, the ultraviolet sterilizer that has closed cavity is installed on the water supply and sewerage pipeline with certain hydraulic pressure usually, and therefore, that ultraviolet sterilizer must adapt to that high hydraulic pressure brings is withstand voltage, the application requiring of seal aspect.Many tubes adopt the sterilizer of single cavity, will cause following consequence in high hydraulic pressure applications:
A. for unsettled hydraulic condition, especially " water hammer " phenomenon that may regional area forms in the sterilizer cavity when unexpected unlatching of water pump, valve is to cause quartz socket tube disruptive key factor.For the form of traditional uv reactor of the shared same single cavity of many tubes, directly impact because of all quartz socket tubes are subjected to current, deal with this type of application conditions, have only increase quartz socket tube wall thickness to improve its compressive property.Because of receptivity and its wall thickness exponent function relation of quartz socket tube to UV-light, the increase of wall thickness of quartz tube will increase the absorption effect of its UV-light greatly, and the water body that causes being sterilized can not reach disinfection standard because of water middle-ultraviolet lamp undercapacity.
The design of traditional uv reactor of the shared same single cavity of b. many tubes because of cavity diameter is big, for meeting withstand voltage standard, must increase considerably the wall thickness of cavity.Cause equipment cost high thus.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of ultraviolet sterilizer that has the built-up type individual cavity, and it is simple in structure and can improve sterilization effect.Traditional uv reactor that can effectively overcome " the shared same single cavity of many tubes " causes the shortcoming of " equipment cost is high, withstand voltage properties is poor, sterilisation effect instability, equipment be difficult to stdn " in actual applications inevitably, with the application prospect that advances ultraviolet sterilizer in fields such as municipal living water, process water, pool direct-drinking water, hotel's direct-drinking water, middle water reuse, fishery cultivatings greatly.
