Abstract
The utility model discloses an ultraviolet digestion device. The ultraviolet digestion device comprises an ultraviolet lamp and a transparent tube which is arranged outside the ultraviolet lamp and is used for a water sample to flow. According to the utility model, by using the transparent tube which is arranged outside the ultraviolet lamp and is used for the water sample to flow, the water sample can flow circularly for digestion in the ultraviolet digestion device; the digestion efficiency is high; and the reagent amount is small.
Description
Technical field
The utility model relates to online environment monitoring and analytical chemistry field, in particular a kind of ultraviolet digestion instrument.
Background technology
Water sample is setting about carrying out need to carry out certain pre-service sometimes before the analyzing and testing.The solid matter of varying number is contained in most of natural water and various sewage, waste water regular meeting, thereby makes water turbidity.These solid matters possibly be inorganicss, also possibly be organism, like sandstone ore particle, aluminosilicate, carbonate, sulfate, iron oxide hyrate and various microorganism and plant and animal residues etc.When measuring the index of inorganicss such as metal,, need earlier through clearing up processing if when containing organism in the water sample.The purpose of clearing up is to destroy organism, dissolving suspension, the burning of various forms (valence state) is become single high valence state, so that measure.Water sample after clearing up should limpid, transparent, nothing deposition.Digestion system is widely used at online environment monitoring and analytical chemistry field etc.The method of clearing up has acid, alkali formula etc.But adopt acid to clear up, like nitric acid-sulfuric acid, nitric acid-perchloric acid, sulfuric acid-potassium permanganate etc. more.The form of clearing up also has high temperature to clear up with ultraviolet to clear up etc.It is the little organic compound by means of in shortwave (180nm-254nm) the ultraviolet ray irradiation decomposition water that ultraviolet is cleared up, like methyl alcohol, ethanol etc.When the strong ultraviolet lighting of the sufficient dosage that produces when ultraviolet equipment is mapped to water, liquid or air; Wherein each kind of bacterium, virus, microorganism, parasite or other pathogen are under the radiation of ultraviolet light UV-C; DNA, RNA in the cell tissue are destroyed; Thereby stop the regeneration of daughter cell; UV sterilizer under the situation of not using any chemical agent, in the short period (be generally 0.2-5 second) killed in the water, bacterium and virus in liquid or the air more than 99.9%.Scientific experimentation proves, wavelength possesses in the ultraviolet ray of 240-280nm the efficient sterilizing function is arranged.Adopt the on-line monitoring appearance of this ultraviolet digestion system to be applied to monitorings such as drinking water source ground, surface water, tap water, river, lake water, seawater, pollution source.But to the ultraviolet digestion system clear up efficient and little amount of reagent is had higher requirement.
Summary of the invention
The utility model problem to be solved provides the ultraviolet digestion instrument of a kind of high-level efficiency, little amount of reagent.
The technical scheme that the utility model ultraviolet digestion instrument is adopted is: the ultraviolet digestion instrument comprises the transparent tube in order to the water sample of flowing through that UV-lamp is outside with being arranged at UV-lamp.
In the such scheme, preferred said transparent tube is the spiral fashion transparent tube, and said spiral fashion transparent tube is surrounded on said UV-lamp outside surface.
In the such scheme, said spiral fashion transparent tube also is provided with airtight steel cage outward.
The beneficial effect of the utility model is: the utility model is through control pump, sample introduction stream switch, the open and close that goes out a kind stream switch, UV-lamp; Realization auto injection and water sample circulate in ultraviolet digestion instrument to be cleared up; Clear up the efficient height, amount of reagent is little.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:
Fig. 1 is the structural representation of the embodiment of the utility model;
Fig. 2 is the cross-sectional schematic of Fig. 1.
Embodiment
Like Fig. 1, shown in Figure 2, the ultraviolet digestion instrument comprises UV-lamp 1 and is surrounded on the spiral fashion transparent tube 2 on the UV-lamp 1 that spiral fashion transparent tube 2 is covered with airtight steel cage 3.
In the utility model specific embodiment when work,, at first, outside water sample gets into from spiral fashion transparent tube 2 inlets, and the water sample circulation system through the outside repeatedly loop is streamed through UV-lamp 1 outside surface, clears up and accomplishes the back from the outlet outflow.
The above is merely the preferred embodiment of the utility model; Can not be in order to restriction the utility model; Any modification of being done within every spirit and principle at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model claim.
Claims (3)
1. ultraviolet digestion instrument is characterized in that: said ultraviolet digestion instrument comprises the transparent tube in order to the water sample of flowing through that UV-lamp is outside with being arranged at UV-lamp.
2. ultraviolet digestion instrument according to claim 1, it is characterized in that: said transparent tube is the spiral fashion transparent tube, said spiral fashion transparent tube is surrounded on said UV-lamp outside surface.
3. like the said ultraviolet digestion instrument of claim 2, it is characterized in that: said spiral fashion transparent tube also is provided with airtight steel cage outward.
