The liquid sampling device has the advantages that samples can be taken out from each effect evaporator conveniently under vacuum environment without stopping the vacuum pump during evaporation, and accordingly evaporation is performed stably and highly efficiently, and the liquid sampling device is applicable to vacuum systems.
Description
Technical field
The utility model belongs to the sampler of determining material property, and is particularly a kind of in the evaporation equipment operational process, carries out the device of liquid sampling from its vacuum environment.
Background technology
Evaporation is widely used in chemical field as a kind of chemical engineering unit operation.Its purpose generally has: the solution that obtains to concentrate is directly as chemical products or semi-manufacture; Remove solvent by evaporation, solution is carried dense, separate out product through crystallisation by cooling again to hypersaturated state; Remove impurity, obtain pure solvent.Because the solvent vaporization needs to absorb a large amount of heats, therefore evaporation operation is a large amount of catabiotic processes, the secondary steam of giving birth to the generation of Steam Heating solution evaporation still has great latent heat, so the utilization again of secondary steam has determined the economy of evaporation technology to a great extent.And the secondary steam of low potential temperature utilizes again, must reduce the saturation temperature of back single-effect evaporator and keep certain heat transfer temperature difference to guarantee enough expulsive forces, so the mode of operation of evaporator mostly is the triple effect evaporation vacuumizing.
Although the purpose of evaporation operation is a separating substances, but the essence of its process is the transmission of heat rather than the transmission of material, the speed of solvent vaporization depends on the intensity of thermal source, and the potential temperature of giving birth to steam and secondary steam is different, so, the evaporation rate of triple effect is different, so, must control the solution concentration of triple effect according to design concentration, just can make the operation of the constant stability and high efficiency of evaporation process, and the fluctuation of inlet amount, quality of steam, follow-up linking technology makes all the action need of evaporator constantly change and regulation and control.At present, the instrument and meter that much is used to monitor concentration is arranged, but in view of evaporation operation has characteristics such as the high temperature that is different from other chemical industry operation, high pressure, high leakproofness, the radioactive density meter that only is installed on evaporator external is more suitable, but it costs an arm and a leg, and there is potential harm in radioactive source to human body.So, do not destroying under the safe operation state of vacuum environment, the solution in the evaporator is carried out sample analysis seem particularly important, also need simultaneously some the sample sampling in the evaporation process is preserved.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned difficulty of taking a sample under vacuum environment, a kind of vacuum sampling device to be provided, and this device can guarantee in the evaporator operational process, need not stop vacuum pump and directly safety sampling smoothly from each single-effect evaporator.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of fluid sampling device that is used for vacuum system, by stop valve, the sampling hut, atmospheric valve, extraction valve, exhaust tube is formed, the sampling hut is a pipeline section, length is determined according to the sample volume of each plan, the two ends, sampling hut are provided with external thread, one end links to each other with the stop valve of same diameter, and other end outlet is connected with atmospheric valve, and stop valve one end is provided with the internal thread stainless steel ball valve, be connected with the joint external thread of evaporator during use, at sampling hut's top side wall perforate welding exhaust tube, exhaust tube and sampling hut are 15 °～75 ° gradients installations, and the exhaust tube other end and extraction valve are for being threaded, the extraction valve outer end is provided with screw thread, lateral with the vacuum trunk line during use is connected, and the extraction valve bottom installs articulation a little more than stop valve additional between extraction valve and the lateral.
The beneficial effects of the utility model are, in evaporation process, can stop vacuum pump and under vacuum environment, from each is imitated, take out sample comparatively easily, in time analyze the concentration of current solution, control the solution concentration of each effect in strict accordance with design parameter, make evaporation process stable, carry out efficiently.
The utility model is applicable to the vacuum system fluid sampling device that the solution in the evaporator is carried out sample analysis.
