Abstract
The utility model relates to a high-temperature high-pressure micro-reflux water sample digestion instrument for monitors, which is composed of a casing and a liquid chamber with unequal diameters. An upper end opening and a lower end opening of the liquid chamber are respectively a safety opening and a feeding opening, a heating area and a micro-reflux area are respectively arranged inside the safety opening and the feeding opening, a heating film is uniformly plated on the outer wall of the liquid chamber corresponding to the heating area, and a spiral heating film is plated on the outer wall of the liquid chamber corresponding to the micro-reflux area. The utility model utilizing the heating films to stably and reliably heat the heating area and the micro-reflux area, which can not only effectively heat liquid entering the heating area under constant temperature and constant pressure, but also realize micro-reflux of liquid in the micro-reflux area in a spiral heating form. The utility model has the advantages of simple structure, high digestion efficiency, safety, reliability and the like, can be widely used for laboratory instruments or on-line monitoring instruments needing to perform chemical reaction for water samples under conditions of high-temperature and high-pressure, and realizes fast digestion of the water samples.
Description
Technical field
The utility model relates to a kind of monitor little backflow water sample of High Temperature High Pressure digestion instrument.
Background technology
Along with the fast development of industrial economy, make in the city problem of environmental pollution serious day by day, environmental pollution has become by the major issue of whole society's common concern.Along with the improving constantly of people's environmental consciousness, more and more pay attention to for content of harmful in the water and control thereof in recent years, therefore, the environment water quality monitoring is to administer the prerequisite that water pollutes.In measuring water body during some pollution factors, need under the little back flow reaction environment of High Temperature High Pressure, the measured matter in the detected water sample be changed into the high material of a kind of selectivity, be clearing up of water sample, detect by methods such as luminosity colorimetric or titration then, the stability of digestion process and height circulation ratio have directly determined the accuracy of measurement result.In the prior art, realize that the mode that the little backflow of water sample High Temperature High Pressure is cleared up mainly contains following several: the first adopts the method for aluminium block to the liquid chamber heating, promptly adopt the aluminium block heating to realize the accurately control of stepped temperature, this kind type of heating presents little reflux state certain degree of difficulty is arranged being heated liquid, even if realize this function reluctantly, but the precision of its temperature control is also very low, and this device volume is huge, is difficult to guarantee the accuracy and the reliability of instrument as the core component of water quality monitoring (WQM) instrument.It two is to adopt the method for heater strip to the liquid chamber heating, being about to nichrome wire is wrapped on the glass housing of liquid chamber, because the resistance of heater strip is inhomogeneous, cause the resistance of the heater strip of winding to differ greatly, cause heat-up time that the heating power difference causes and heating to clear up effect and differ very big, finally cause the accuracy of the Monitoring equipment determination data that adopts this type of heating and consistence to be difficult to assurance.It three is to adopt the method for microwave to the liquid chamber heating, and this kind method is the cost height not only, and the danger of microwave leakage unavoidably occurs, so this kind type of heating is used for the key part of the on-line monitoring instrument of unattended duty, and its reliability is very poor.
Summary of the invention
The utility model purpose be to provide a kind of simple in structure, can overcome prior art deficiency, stable, reliable, the safe little backflow water sample of High Temperature High Pressure digestion instrument.
The utility model purpose be achieved in that this monitor with the little backflow water sample of High Temperature High Pressure digestion instrument by housing be assemblied in the housing waney liquid chamber and form, the upper and lower port of described liquid chamber is respectively safety mouth and fluid inlet, be divided into heating zone and little recirculating zone in it, evenly be coated with heating film on the liquid chamber outer wall of heating zone correspondence, be coated with the spirrillum heating film on the liquid chamber outer wall of little recirculating zone correspondence.
The technical progress that the utility model is obtained: the little backflow water sample of this High Temperature High Pressure digestion instrument adopts heating film that reliable and stable heating is carried out in heating zone and little recirculating zone, not only can effectively guarantee the liquid that enters into the heating zone is heated under constant temp and pressure, but also can realize little backflow in little recirculating zone of spirrillum type of heating.Advantages such as this device has simple in structure, clears up the efficient height, and is safe and reliable can be widely used in carrying out water sample the Laboratory Instruments or the on-line monitoring instrument of chemical reaction under high-temperature and high-pressure conditions, realize clearing up fast water sample.
Description of drawings
Fig. 1 is the utility model one-piece construction synoptic diagram.
Embodiment
Be that embodiment is to the utility model further instruction below with the accompanying drawing.As shown in Figure 1, this monitor with the little backflow water sample of High Temperature High Pressure digestion instrument by housing 1 be assemblied in the housing 1 waney liquid chamber 2 and form, the upper and lower port of described liquid chamber 2 is respectively safety mouth 11 and fluid inlet 4, be divided into heating zone 3 and little recirculating zone 8 in it, heating zone 3 is 1: 1.5～1: 2 with the volume ratio of little recirculating zone 8, and present embodiment is 1: 1.8.Evenly be coated with heating film 7 on liquid chamber 2 outer walls of heating zone 3 correspondences, be coated with spirrillum heating film 9 on liquid chamber 2 outer walls of little recirculating zone 8 correspondences, described heating film 7 can be METAL HEATING PROCESS film or oxidation heating film, and present embodiment is the METAL HEATING PROCESS film.The power supply lead wire 10,5 of heating film 7,9 is located at the upper and lower end parts of heating zone 3 and little recirculating zone 8 respectively, when power connection plating in the heating zone 3 and the heating film 7,9 of little recirculating zone 8 produce heat energy simultaneously, heat by the water sample in 3 pairs of liquid chambers in heating zone 2, and in little recirculating zone 8 of spirrillum type of heating, water sample is realized clearing up fast of little backflow.Be the convenient temperature that monitors in the heating zone 3,3 top is provided with temperature-measuring port 6 in the heating zone.
