Description
Technical field
The utility model relates to a kind of radon chamber toxic emission automaton.
Background technology
The standard set-up that radon chamber is demarcated as emanometer, researchers are devoted to how to guarantee that the condition such as radon consistence, humiture in radon chamber keeps constant, but after radon chamber completes demarcation, radon gas in radon chamber just becomes waste gas, these waste gas is needed to process, make the radon consistence in radon chamber return to normal level, radon chamber could be opened and the instrument of the inside is taken out; Generally, this concentration is tens times of ambient concentration even hundred times, if directly by the radon discharge in radon chamber, can cause radioactive contamination like this to the environment around radon chamber; If allow radon natural decay in radon chamber, expend time in longer, be unfavorable for increasing work efficiency; Conventional method utilizes activated charcoal to the suction-operated of radon, discharged by the radon gas in radon chamber, but the suction-operated of activated charcoal is limited after charcoal absorption; Therefore, the utility model proposes a kind of radon chamber toxic emission automaton, after the test that radon chamber completes instrument, the radon waste gas in radon chamber is processed, environmental radiation contact scar can not be caused, and can increase work efficiency.
Summary of the invention
The utility model is intended to propose a kind of radon chamber toxic emission automaton, this device can after radon chamber staking-out work terminates, discharge again after radon waste gas in radon chamber is processed, do not cause the radioactive contamination of environment, and do not affect normal staking-out work.
To achieve these goals, a kind of radon chamber toxic emission automaton that the utility model proposes, it comprises main control unit, radon chamber waste gas storage element, radon chamber toxic emission unit, radon consistence monitoring means and display unit.
Described radon chamber toxic emission automaton, its physical arrangement is by radon chamber by gas exhaust duct, pneumatic pump, solenoid valve and waste gas reservoir vessel and gas exhaust duct, and solenoid valve, pneumatic pump are connected.
Described radon chamber toxic emission automaton, its control section is connected with solenoid valve, pneumatic pump by digital independent transport module, main control unit by emanometer.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the utility model radon chamber toxic emission automaton.
Fig. 2 is the structural representation of the utility model radon chamber toxic emission automaton.
Embodiment
As a kind of preferred version, STM32 selected by processor described in the utility model, and this chip internal is integrated with ADC acquisition function block.
Below in conjunction with accompanying drawing, the utility model is further described.
The theory diagram of the radon chamber toxic emission automaton that Fig. 1 provides for the utility model, comprises main control unit, radon chamber waste gas storage element, radon chamber toxic emission unit, radon consistence monitoring means and display unit.Main control unit is primarily of STM32 controller, buffer circuit composition; Radon chamber waste gas storage element is primarily of radon chamber, gas exhaust duct, pneumatic pump, solenoid valve, waste gas reservoir composition; Radon chamber toxic emission unit is primarily of waste gas reservoir vessel, solenoid valve, aspiration pump, gas exhaust duct, activated charcoal composition; Radon consistence monitoring means is primarily of emanometer, digital independent transport module composition; Display unit is made up of LED and display screen.
The structural representation of the radon chamber toxic emission automaton that Fig. 2 provides for the utility model, arrow points is airflow direction; By radon chamber is connected by gas exhaust duct, solenoid valve, pneumatic pump with waste gas reservoir, then waste gas reservoir is connected by gas exhaust duct, solenoid valve, pneumatic pump and container that activated charcoal is housed; Radon chamber is also directly connected by gas exhaust duct, solenoid valve, pneumatic pump and container that activated charcoal is housed; Air enters in environment through gas exhaust duct, pneumatic pump by the container that activated charcoal is housed.
Described radon chamber toxic emission automaton, concrete implementation step is as follows.
1. radon chamber toxic emission: at radon chamber timing signal, open the pneumatic pump that the solenoid valve between waste gas reservoir and the container that activated charcoal is housed, pneumatic pump and activated carbon container lead to environment to open, air in waste gas reservoir is taken away, calculate according to the radon consistence in the volume ratio of radon chamber and waste gas reservoir and radon chamber and need pumpdown time, after reaching this time, close above-mentioned all devices; After radon chamber staking-out work terminates, open radon chamber and waste gas stores the solenoid valve and pneumatic pump that go, by the radon waste gas suction waste gas reservoir in radon chamber, waste gas reservoir internal gas pressure close to atmospheric pressure or according to the radon consistence in theory calculate radon chamber close to normal level time, stop being vented in waste gas reservoir; Then the solenoid valve between radon chamber and environment is opened, prevent radon chamber from bearing atmospheric pressure overlong time, calculate solenoid valve opening time, when radon chamber internal gas pressure is close to normal atmosphere (An), the pneumatic pump that solenoid valve between radon chamber and the container that activated charcoal is housed, pneumatic pump and activated carbon container lead to environment is opened, carries out flow gas cleaning.
2. Concentration Testing and display: when radon chamber carries out toxic emission, radon consistence in radon chamber reduces gradually, emanometer detects the radon consistence in radon chamber in real time, emanometer simultaneously in waste gas reservoir also needs the radon consistence in inspection instrument, emanometer in two containers imports data into controller in real time by digital independent transport module, and after controlling data to be carried out process, display in real time on a display screen; When the radon consistence in radon chamber returns normal level, just can open radon chamber and take out by the instrument demarcated.
3. toxic emission in waste gas reservoir: after radon chamber has been demarcated, radon waste gas in radon chamber is all stored in waste gas reservoir, according to the Decay Law of radon, radon consistence in reservoir can reduce, after a period of time, the change of radon consistence is observed by the emanometer in waste gas reservoir, when concentration reaches discharging standards, just the radon waste gas in reservoir can be discharged, if staking-out work is more frequent, multiple waste gas reservoir can be added in systems in which, if demarcate infrequently, just can deposit in reservoir always, radon consistence can be reduced to normal level gradually.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
