Problems solved by technology
[0002] At present, the laboratory does not have special equipment for toxicity experiments on volatile organic compounds. During the experiment, organic pollutants tend to volatilize outward, which reduces the accuracy of experimental data. Moreover, organic compounds in water volatilize into the air, reducing the The concentration of organic matter in the water, thereby reducing the toxicity of the polluted water body and affecting the experimental data

The invention discloses a volatile organic compound toxicity test device, which aims to solve the problem that air leakage is easy to occur during the volatile organic compound toxicity test, and the water has the opportunity to volatilize into the air to reduce the toxicity of the water body, which affects the accuracy of the experimental data. . The invention comprises a closed test box and a piston cylinder. Water is housed in the test box, and the bottom of the test box is connected with an air intake pipe. The pumping pipe is connected between the piston barrel, the pumping piston is installed in the piston barrel, and the rotating shaft is installed outside the piston barrel, and the pull rope is wound on the rotating shaft, and the pulling rope is connected to the pumping piston; the ring pipe and the fan are installed in the experiment box, and the lower part of the ring pipe is placed in water. , the upper part of the annular pipe is tangentially connected to the air outlet pipe, the air outlet pipe is connected to the air outlet of the fan, the air inlet of the fan is placed above the water surface in the test box, and a number of air outlet holes are arranged at intervals on the part of the annular pipe placed in the water.
Description
Technical field [0001] The present invention relates to an organic toxic experimental device, and more particularly, it involves a volatile organic toxic experimental device. Background technique [0002] At present, the laboratory is a toxicity experiment in a toxicity experiment, which is prone to except for organic pollutants during the experiment, and reduces the accuracy of the experimental data, and the organic matter in the water is volatilized, and the organic matter in the water is volatilized into the air, and the water is volatilized into the air, lowered The organic material concentration in the water reduces the toxicity of the contaminated water, affecting the experimental data. Inventive content [0003] The present invention overcomes the volatile organic toxic experiment, it is prone to leakage phenomena, and the opportunity to volatilize the toxicity to the air to reduce the toxicity of the water, affecting the premieration of the experimental data, provides a ...
