Embodiment Construction

[0010] As shown in Figure 1, the present invention includes a gas distribution system, a sample positioning frame, a heating device, a vacuum system and a solvent recovery system. The air distribution system includes an air source 9, a pressure reducing valve 8, an air distribution cabin cover 7, an air distribution cabin 6 and a thin air blowing tube 5, the heating device includes a temperature control device 11 and a water bath 1, and the sample positioning frame is provided with a sample fixing frame 2 1. A graduated sample concentrator 3 is arranged on the sample holder, and the vacuum system includes a vacuum pump 12 , a vacuum chamber 4 and a vent valve 10 . The connection structure of the equipment is shown in the figure. The air source 9 and the pressure reducing valve 10 are connected to the side of the air distribution cabin 6. The upper surface of the air distribution cabin is open. 7 is located at the gas distribution cabin 6 upper ends. The gas distribution chamb...

Abstract

The present invention relates to experiment device for sample concentration, which comprises air distribution system composed of air source, pressure reducing valve, air distribution hatch cover, air distribution hatch and air blow tubule; sample location frame with calibrated sample concentrator; heater composed of temperature control device and water bath; vacuum system composed of vacuum pump, vacuum hatch and atmospheric valve; and solvent recovery system. Inert gas or air passes tubule with high speed for the negative pressure of vacuum hatch and differential pressure of two ends of tubule and forms high speed air flow to blow and clean liquid sample in concentration tube, gasify and bring out liquid solvent quickly, and decrease concentration time; meantime, use solvent recovery system to decrease pollution.

Description

technical field [0001] The invention relates to an experimental device used for sample concentration and solvent recovery by a negative pressure environmental protection concentrator. Background technique [0002] The negative pressure environmental protection concentrator is mainly used for the concentration of extraction liquid samples containing organic solvents, and can process multiple samples at a time. Usually, the negative pressure environmental protection concentrator is composed of a gas distribution system, a sample positioning frame, a heating device and a solvent recovery system. The pressurized inert gas passes through the gas distribution system (the gas distribution cabin cover is required) or the normal pressure air passes through the gas distribution system (the gas distribution cabin cover is not required), and passes through the thin blowing tube with pressure difference at both ends to form a high-speed airflow blowing It is fixed on the sample position...
