Organic liquid volatilizing and treating device with controllable conditions

Abstract

The invention discloses an organic liquid volatilizing and treating device with controllable conditions. The device comprises a tank body, a temperature controlling device, a pressure controlling device, an absorbing device, a condensing recovery device, a membrane separation device and an activated carbon adsorption device. The device can individually conduct VOC sample collection on various kinds of organic liquid, VOC source spectrums volatilized by all the kinds of organic liquid are obtained, and the interference of other VOC discharging sources is avoided; the actual temperature and pressure of the tank body can be simulated, and VOC discharging source spectrums of a storage tank can be sampled under different conditions of the four seasons, so that the collected VOC source spectrumsamples meet the actual discharging conditions; common organic gas treatment methods of an absorbing method, a condensing method, a membrane separation method, an adsorption method and the like can beindividually selected or used in a combining mode, so that VOC species in the sample organic gas is consistent with the actual conditions, and the discharging conditions of VOC species of gas generated and volatilized by different kinds of organic liquid after the treating device can be differentiated.

Description

technical field [0001] The invention relates to an organic liquid volatilization and treatment device, in particular to a condition-controllable organic liquid volatilization and treatment device, which belongs to the technical field of environmental monitoring instruments. Background technique [0002] The petrochemical and chemical industry uses a large number of storage tanks to store organic liquids. Due to the volatilization of organic liquids, the discharge of storage tanks has become an important source of VOC in the atmosphere. Since various VOC species have different impacts on the atmospheric environment and human health, and there are many types of organic liquids stored in storage tanks, the VOC species and composition characteristics produced by volatilization are also different. Therefore, it is necessary to quantify the storage process of various different liquids. The proportion of various VOC species emitted in the environment is used to determine the source...

Problems solved by technology

Moreover, in actual operation, the gases discharged from multiple storage tanks are often collected and processed in a unified manner, and it is impossible to distinguish the discharge information of the storage tanks that store a specific substance.
