[0002] Dimethyl carbonate has a pungent odor and is irritating and toxic to the human respiratory tract, digestive system, skin and eyes. Contact with skin and eyes may cause symptoms such as stinging, redness and swelling. Inhalation of high concentrations may cause coughing, sore throat and even suffocation.

[0003] When the existing dimethyl carbonate tank truck is unloading, the feed port on the top of the dimethyl carbonate storage tank needs to be opened, because during the unloading process, a vacuum is gradually formed in the tank, making it difficult to continue unloading. Therefore, the feed port on the top of the tank needs to be opened to allow air to enter to balance the air pressure and complete normal unloading. However, since the feed port on the top of the tank is open, dimethyl carbonate gas will be discharged to the outside, which is not good for the health of workers and will pollute the atmosphere. Utility Model Content

[0004] The utility model aims to provide a dimethyl carbonate tank truck unloading auxiliary device, which solves the problem that when unloading, due to the opening of the feed port on the tank top, dimethyl carbonate gas will be discharged to the outside, which is not conducive to the health of workers and will pollute the atmosphere.
