The utility model greatly reduces the time of water sample digestion in the water quality monitoring process, the seal reaction for ten minutes under the temperature of 200 DEG C can attain the same oxidized effect as the reaction for two hours under the temperature of 146 DEG C in the standard method, and the actual COD value of sewage can be accurately measured.
Description
Technical field
The utility model relates to environment automatic on-line monitoring instrument device field, relates in particular to a kind of pressure dispelling reactor.
Background technology:
Chemical oxygen demand (COD) (Chemical Oxygen Demand) is a most important contamination index in the monitoring water environment, it can be in order to judge the relative content of reducing substances (mainly being organism) in the water body, effect for water quality monitoring and processing, it is an important parameters, for the improvement of water pollution control and quality of water environment provides foundation, the pressure dispelling reactor is the important component part of COD water quality on-line monitoring instrument device, reactor is the container of various liquid mixing heating, the reactor that opens wide heating is subjected to the influence of reaction solution and makes the temperature of backflow system generally not high, adopt under the normal pressure in the standard law (GB11914-89) and clear up, reaction conditions is 146 ℃ of following oxidations 2 hours, could be relatively near the actual value of sewage.If require heat time heating time short, under the situation, heating obviously is worthless to measurement result under the normal pressure really and accurately.Airtight heating has obtained application in chemico-analytic laboratory, but this technology is not applied in the COD automatic on-line monitoring instrument device.Because as a closed container, under heating condition, need to take into full account the maximum pressure that it can bear, under high-temperature condition, do not clear up organic problem fast and also there is a kind of device effectively to solve at present.
Summary of the invention
The utility model purpose is the pressure dispelling problem of reactor in COD automatic on-line monitoring instrument device that makes with glass material in order to solve.
The utility model provides a kind of pressure dispelling reactor, outer wall place at reactor is provided with heating source, the top of reactor is the condensation of gas chamber, reactor communicates with the condensation of gas chamber, this condensation of gas chamber is set in the cooling tube, and cooling tube is provided with cooling water intake and cooling water outlet, is provided with the sample introduction pipe between reactor and condensation of gas chamber, drain pipe is housed in the reactor, is equiped with temperature tester on the reactor outer wall.
We are according to the needs of real reaction condition, the pressure in the reactor is improved and be controlled in the 0.11-0.13MPa.Such reaction conditions can improve the temperature of reaction to 200 ℃ in the container, has shortened the time of clearing up water sample greatly, improves oxidation efficiency.In heating process, in order to guarantee safety, temperature in the reactor is infinitely increased, we in the upper design of reactor special water cooling plant, promptly at the peripheral suit of condensation of gas chamber one cooling tube, feed the chilled water that constantly flows in the cooling tube, when the hot gas that liquid produces in the reactor during heating constantly rises to condensation chamber, by ice-cold condensation locular wall cooling liquid, thereby the air pressure of the inside is controlled in the 0.13MPa, the continuous rising of pressure in the reactor when having avoided heating, because the pressure in the reactor has increased, make the temperature in the reactor reach as high as 200 ℃, under high like this temperature, making those may be in the critical organism of clearing up can nearly all be cleared up in the short time fully.
Advantage of the present utility model is, shortened the time of clearing up water sample in the water quality monitoring greatly, measurement data is accurate, can reach equal oxidation effectiveness in two hours 146 ℃ of reactions with standard law in 10 minutes 200 ℃ of lower seal reactions, the result of result who measures and standard law (GB-11914-89) is very close, thereby can measure the actual COD value of sewage accurately.Digestion process of the present utility model is in air-tight state, and the chlorion in the water is oxidized to chlorine, in case after reaching vapor liquid equilibrium, the chlorion in the water is just no longer oxidized, thereby has effectively suppressed the interference of chlorion.

Embodiment
It shown in the accompanying drawing most preferred embodiment of the present utility model.The outer wall 3 of reactor is provided with heating source, and the condensation of gas chamber 4 of reactor 2 tops communicates with reactor 2, and the condensation of gas chamber is set in the cooling tube 1, and chilled water flows in cooling tube 1 by cooling water intake 8 and cooling water outlet 6.Be provided with the sample introduction pipe between reactor and gas cooling chamber, the sample introduction pipe can have a plurality of, as sample introduction pipe 5 among the figure and sample introduction pipe 9, drain pipe 10 is housed in the reactor.Top, condensation of gas chamber is provided with blow-down pipe 7, is equiped with temperature tester 11 on the reactor outer wall 3.
When using the utility model pressure dispelling reactor to measure sewage, reaction liquid is through sample introduction pipe 5, and sample introduction pipe 9 enters reactor 2, sealing sample introduction pipe 5, blow-down pipe 7, sample introduction pipe 9 and drain pipe 10.To the reactor heating, solution is in 2 li pressurized power reactions of reactor by reactor outer wall 3 for well heater.Temperature in the reactor constantly increases makes the liquid gasification enter condensation of gas chamber 4, the outer wall of gas cooling chamber 4 is full of chilled water, make the steam liquefaction that produces owing to heating in the reactor, reach the purpose of cooling, make the maximum temperature maintenance in the entire container certain simultaneously.The temperature tester 11 of reactor can be measured the fluid temperature in the reactor at any time.
