Abstract
The invention is applied to ultraviolet sewage treatment in the field of environmental protection. Lamp tubes, the conventional equipment for ultraviolet sewage treatment, have low electrode efficiency and short lives, have large floor areas because of using open channels for flowing and have poor effects. The invention adopts the microwaves sent out by magnetrons as the energy sources. The ultraviolet quartz lamp tubes are arranged in a cylindrical microwave resonance cavity body, are filled with mercury and protective gases, emit ultraviolet light under microwave excitation, have no electrodes and have long lives. A facility for current to flow in and out, with a cylindrical well type structure, and a spiral diversion facility installed in the facility for current to flow in and out canenable water to be fully contacted with the ultraviolet rays, thus obtaining good sterilization effects. The floor area of the invention is only a small percentage of that of the conventional equipment for ultraviolet sewage treatment.
Description
Technical field
The invention belongs to the environmental protection equipment technical field, particularly ultraviolet wastewater is handled sterilization equipment.
Background technology
Bacterium in the water is killed under ultraviolet irradiation, and this is a new developing technology in recent years, is the effective ways of water treatment, is applied in the water sterilization field, is called as ultraviolet water and handles sterilization equipment.Existing ultraviolet water is handled the form that sterilization equipment generally adopts the open channel overcurrent, and floor space is big, regulates the equipment complexity of flow.The core component quartz burner of equipment has electrode, and its shortcoming is that photoelectric conversion rate is low, and luminous efficiency is along with progressively decay duration of service, the life-span only about 10000 hours, the replacing fluorescent tube that this equipment claimed is frequent, maintenance cycle is short and expense is big.
Summary of the invention
The microwave that the present invention adopts microwave magnetron to send at the problems referred to above is done energy source; ultraviolet quartz burner more than one or one is housed in a cylindrical microwave resonant cavity; be filled with mercury and protective gas in the pipe; for example nitrogen, neon, argon gas; under microwave excitation, form ionization, send ultraviolet.Do not have electrode and filament on the fluorescent tube, work-ing life can be more than 50000 hours.The wave frequency that the microwave quartz burner sends is the hundred times of general ultraviolet line lamp, and it has very strong penetration power, and sterilization effect is better in the sewage of muddiness.The microwave UV-lamp does not have the optical attenuation phenomenon in whole lifetime, can expend a large amount of electric energy for the compensation light decay.Because the microwave UV-lamp does not have electrode, so underwater portion is not electrically connected in well, maintenance of the equipment is very easy.
Ultraviolet ray needs a metastable flow in sterilizing process.The present invention adopts cylindrical well type structured, and water enters counterbalance cell from the ingress, and certain water storage is arranged in the counterbalance cell, can play mitigation when the water inlet short period of time surpasses rated flow; When water inlet surpasses rated flow for a long time, can flow out, make the water that flows into ultraviolet disinfector at equilibrium from the overflow weir that is installed in counterbalance cell top.An outlet is arranged below counterbalance cell, and sewage upwards enters in the uv steriliser from the bottom from flowing into the bottom along the borehole wall here again.Uv steriliser is a cylindrical tubular container, and its inside is provided with microwave disinfection by ultraviolet light fluorescent tube, and water flows out from the top through the water after the sterilization here by the ultraviolet sterilization and disinfection.This structure remains certain water yield in well, equipment can can't not move inadequately because of the water yield, and the generation high water head that also can not meet with obstruction because of flow velocity is too high influences aquifer yield.For prolonging time, the raising sterilization effect that water contacts with quartz burner, the volution diaphragm that makes water form eddy flow has been installed on barrel.This device promptly can prolong water and the time that ultraviolet ray contacts, and also can make water fully obtain the irradiation at short distance of UV-light, and sterilization effect is better.The present invention promptly can be applicable to sewage, tap water and handles, and also can be applied in to make sterilization and disinfection equipment in the industry such as nectar and use.Whole water treatment device is cylindrical similar to well, floor space be traditional open channel cross streamed ultraviolet wastewater disinfection equipment 1/10th to 1/20th.
Description of drawings
Accompanying drawing 1 is the main structure chart of disinfection well for ultraviolet sewage treatment by using microwaves
Accompanying drawing 2 is vertical views of Fig. 1
Accompanying drawing 3 is local structure figure of microwave ultraviolet generator among Fig. 1
Embodiment
Water is from the 1 inflow counterbalance cell 3 that enters the mouth, counterbalance cell has certain water storage, the overcurrent of short period of time can be eased in counterbalance cell, when water inlet surpasses rated flow for a long time, can overflow from overflow port 2, reach the purpose of equilibrium water flow, the height official post water that the horizontal plane in the counterbalance cell is higher than water outlet 6 its generations flows out smoothly.The 16th, the water in the flow-guiding mouth, counterbalance cell is between this mouthful inflow borehole wall 12 and the uv steriliser urceolus 11, and the volution water conservancy diversion inlet 15 from the bottom flows in the uv steriliser urceolus 11 again.Rise along being installed in column 13 volution diaphragm 14 on every side, discharge from exporting 6.These devices promptly can prolong water and the time that ultraviolet ray contacts, and also can make water fully obtain the irradiation at short distance of UV-light, and sterilization effect is better.Arrow direction among the figure is a water (flow) direction.Dividing plate 7 works to prevent out that entry is in line.
Microwave is produced by the magnetron 4 that is fixed on the transmitter 5, is located at the top of ultraviolet generator, is positioned at the top of horizontal plane.The microwave that is produced by magnetron 4 is transmitted in the cylindrical cavity 9, and resonator cavity is made of the net metal thing, and its effect has three: the one, microwave is transmitted to quartz burner inside; The 2nd, see through ultraviolet; The 3rd, prevent microwave leakage.Some electrodeless quartz burners 10 are housed in resonator cavity; the effective silica glass of UV-lamp is made, and is in the partial vacuum state in the pipe, is filled with mercury and protective gas; for example: nitrogen, neon, argon gas form mercury vapour generation ionization and send UV-light under the effect of microwave.In the microwave resonator outside, there is a cylindrical quartz glass sleeve pipe 8 to prevent that current from entering in the resonator cavity, appear ultraviolet ray simultaneously, in uv steriliser urceolus 11, load onto some such quartz burners the water that flows through is carried out sterilization and disinfection.Uv steriliser urceolus 11 is that cylindrical upper and lower opening is made with stainless steel, and the borehole wall 12 is cylindrical objects, can make also and can make with other metallic substance or non-metallic material with Steel Concrete.
