Heating equipment for preparing sample

Abstract

The invention belongs to the technical field of nuclear power, and particularly relates to heating equipment for preparing a sample. A water sample to be treated is contained in each heating vessel; each heating pot can perform water bath heating on a heating vessel in the heating pot at a preset temperature; a condensing pipe of the condensing equipment is respectively communicated with each heating vessel, the vacuum device and the waste liquid collecting container through pipelines, and the vacuum device can suck to form a negative pressure environment in the condensing pipe in a working state, so that steam generated by heating a water sample to be treated in each heating vessel enters the condensing pipe through the pipeline; and the condensing pipe condenses the entering steam to form condensate which flows into the waste liquid collecting container. A relatively closed loop is formed among the plurality of heating vessels, the condensing pipe, the waste liquid collecting container and the vacuum device, so that steam overflow in the preparation process is greatly reduced, and the humidity of the laboratory environment is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to a heating device for preparing samples. Background technique [0002] The total β radioactivity content in water can directly reflect the radioactivity level in the water body, and is an important indicator for judging the monitoring of radioactive pollution in water. Carry out monitoring of the total β level of surface water, groundwater, and drinking water around the nuclear power plant, and accumulate data on the total β radioactive level of the water around the nuclear power plant to provide scientific and rapid judgment basis for nuclear and radiation emergencies, which is more conducive to providing the surrounding environmental water body under the normal operation of the nuclear power plant Baseline data for the indicator. [0003] The "Thick Source Method for the Determination of Total β Radioactivity in Water Quality" (HJ 899-2017) stipulates that whe...

Problems solved by technology

The evaporation and concentration takes a long time, consumes a lot of energy, and the temperature is not easy to control. If the control is not good, bumping may occur

Heating with an electric heating plate will generate a large amount of condensed water in the laboratory, which will increase the humidity in the laboratory and affect the service life of other instruments in the laboratory
