Description

Technical Field

[0001] The utility model relates to the technical field of condensation recovery devices, in particular to a condensation recovery device. Background Art

[0002] The waste gas emitted by some factories and laboratories may contain a large amount of volatile organic compounds, which are important precursors of urban haze and photochemical smog. They mainly come from coal chemical industry, petrochemical industry, fuel coating manufacturing, solvent manufacturing and use, etc. Most industrial waste gases have a special unpleasant odor and are toxic, irritating, teratogenic and carcinogenic. Benzene, toluene and formaldehyde in particular can cause great harm to human health. With my country's increasing attention to the environment and the vigorous promotion of green chemical industry, various industries have begun to devote themselves to the recovery and treatment of industrial waste gases. At present, the conventional treatment methods for VOCs mixed gases include adsorption, thermal storage combustion and catalytic combustion (RTO and RCO), liquid absorption and biological treatment.

[0003] After searching, it was found that the announcement number was CN213253086U, and the name was a waste gas condensation recovery device. The application pointed out that the existing treatment methods have problems such as poor treatment effect, low recovery rate, short equipment safety distance, poor explosion-proof performance, high investment cost, etc., and it is difficult to treat industrial waste gas with a high concentration of volatile organic compounds. By arranging a plurality of baffles staggered left and right in the inner cavity of the condensation tank, the baffles and the condensation tank form a tortuous gas passage, so that the waste gas has a long residence time when entering the condensation tank, and the waste gas tumbles left and right in the condensation tank to increase the degree of chaos, which is conducive to the waste gas to fully contact with the U-shaped condenser tube and enhance the condensation and liquefaction effect; the baffle is arranged to be tilted downward, so that the condensed and liquefied organic matter can flow directly along the baffle to the bottom of the condensation tank, and through the multiple U-shaped condensers in each condensation tube group are arranged together, and the multiple condensation tube groups are arranged side by side, they can be fully and evenly distributed in the inner cavity of the condensation tank. It is beneficial for the exhaust gas to fully contact with the U-shaped condenser, thereby improving the condensation and liquefaction effect; the two end openings of the U-shaped condenser are located at the top, which is more convenient for connecting to circulating cold water. The circulating cold water equipment only needs to be placed above the condenser tank, reducing the space occupancy rate. At the same time, by providing a spherical convex portion on the U-shaped condenser, the heat exchange area between the condenser and the exhaust gas can be increased, and the condensation and liquefaction efficiency of volatile organic matter in the exhaust gas can be improved. However, when the application is in use, it is difficult to achieve efficient tumbling of the exhaust gas by relying solely on the baffle of the baffle. The heat exchange area increased by the spherical convex portion is limited. At the same time, the specific surface area of ​​the U-shaped condenser is not large enough when distributed in a plane, and the heat exchange efficiency is not high enough. Further improvements can be made. At the same time, there is a lack of structure above the solenoid valve to prevent gas from entering the liquid storage tank. When the liquid inside the condenser tank is completely discharged, the uncondensed gas will also enter the liquid storage tank, causing pollution of the recycled material and leakage of the gas, which also affects the work efficiency. Further improvements can also be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
