Description

Technical Field

[0001] The present invention relates to the technical field of VOCs treatment, and particularly to a controllable negative pressure volatile organic compound swirl cooling component. Background Art

[0002] According to the definition of the World Health Organization, VOCs are various organic compounds with boiling points from ℃ to ℃ at normal temperature. In China, VOCs refer to organic compounds with a saturated vapor pressure greater than 70 Pa at normal temperature and a boiling point below 260 °C under normal pressure, or all organic compounds with a vapor pressure greater than or equal to 10 Pa and volatility at 20 °C. The main components of VOCs are: hydrocarbons, halogenated hydrocarbons, oxygenated hydrocarbons, and nitrogenous hydrocarbons, which include: benzene series, organic chlorides, Freon series, organic ketones, amines, alcohols, ethers, esters, acids, and petroleum hydrocarbon compounds, etc.

[0003] Currently, for VOCs gases, a multi-stage spraying method is mostly used in the front stage to capture various condensable organic matters therein and reduce the gas temperature. Since the chemical compositions and physical properties such as temperature and condensation point of different VOCs gases are different, the residence time required for them in the front-stage spraying is also different. According to the properties of different VOCs gases, how to reasonably control their residence time in the spraying section, effectively save energy and improve the treatment efficiency is an urgent problem to be solved at present. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a controllable negative pressure VOCs swirl cooling component, which can linearly adjust the residence time of different VOCs gases in the spraying section according to their chemical compositions and physical properties such as temperature and condensation point, and effectively reduce the energy consumption of the equipment and improve the treatment efficiency of the controllable negative pressure volatile organic compound swirl cooling component.

The front section of the intake pipe is connected with a multi-stage spraying device. The rear section of the cyclone pipe is connected with a non-condensable gas cooling pipe manifold. The VOCs gas that has not been completely cooled by the multi-stage spraying in the front section flows through the intake pipe, the flow-accumulating diffusion pipe, the confluence pipe, and the cyclone pipe in turn under the negative pressure condition. The opening degree of the flow-accumulating diffusion pipe is adjusted by the electric actuator, the connecting rod, and the conical valve, and the magnitude of the negative pressure is linearly adjusted to control the residence time of the VOCs gas in the multi-stage spraying device in the front section, effectively reducing the energy consumption of the equipment.
