Device and method for synergistically enhancing two-fluid atomization performance

Abstract

The invention discloses a device and a method for synergistically enhancing a two-fluid atomization performance. The device is formed by connecting multiple stages of two-fluid atomization units in series, wherein the output of a gas-liquid mixing unit in the previous stage of two-fluid atomization unit is connected with the input of a liquid feeding unit in the next stage of two-fluid atomization unit; the output of the last stage of two-fluid atomization unit is used as the output of the whole device; and a heating device is further arranged in the liquid feeding unit. According to the device and the method for synergistically enhancing the two-fluid atomization performance provided by the invention, liquid or fog drops are heated, so that the acting force between liquid molecules is reduced, and the liquid drops can be broken easily. Through the multi-stage series connection mode, the flow of gas-liquid mixed liquid is greatly increased compared with the previous stage, the reaction in each two-fluid atomization device unit is more violent compared with the previous stage, the effect of generating high-speed jet flow with low energy consumption can be achieved, and the quality of generated fog drops is higher.

Description

technical field [0001] The invention belongs to the technical field of atomization and dust removal, and in particular provides a device and method for synergistically enhancing the performance of two-fluid atomization, which are used to reduce the content of particulate matter with a particle size less than or equal to 2.5 μm in the atmosphere. Background technique [0002] With the rapid growth of my country's social economy and the rapid advancement of urbanization and industrialization, the huge demand for resources and energy consumption have added a heavy environmental burden to social development. The generation and diffusion of a large amount of atmospheric particulate matter (PM2.5, PM10, TSP, etc.) not only adds many health and safety risks to urban residents, but also causes permanent damage to employees from pneumoconiosis. The deadline for rectification or even shutdown of production poses a serious threat to my country's sustainable development strategy and ecol...
