Embodiment 1

[0026] Such as figure 1 As shown, the device of the present invention includes a fluid mixer 1, a fluid dynamic sound wave generator 3 and a gas-liquid separator 4, and the fluid mixer includes a mixing pipeline and an atomizing nozzle 2, wherein the atomizing nozzle 2 is arranged in the mixing pipeline On the pipe wall, the mixing pipe preferably adopts a pipe with a variable cross-sectional area. The change of the cross-sectional area causes the change of the gas pressure and flow in the pipe, and the speed of the gas can be controlled within a certain range. The outlet of the fluid mixer 1 is connected to the fluid dynamic sound wave generator. Connect the outlet of the hydrodynamic acoustic wave generator to the inlet of the gas-liquid separator, and the gas-liquid separator separates the purified gas from the washing liquid containing pollutants.

[0027] The hydrodynamic sound wave generator can be selected from Hartmann sound wave generator, Pallman sound wave generator...

Abstract

The invention discloses a method and device for washing and hot mass transfer of pollutants in gas. The method comprises the following steps: (1), atomizing washing liquid; (2), mixing gas fluid containing pollutants with the atomized washing liquid so as to obtain mixed fluid; (3), after the mixed fluid is subjected to washing and hot mass transfer through a sound wave generator, carrying out gas-liquid separation, so as to obtain purified gas and washing liquid containing the pollutants. According to the method, after the pollutants with a certain energy and speed are mixed with the washing liquid, full collision, breaking, adsorption, coagulation and energy transfer are carried out in a pressure field generated by the sound wave generator, so that efficient washing and hot mass transfer of the pollutants are realized.

Description

technical field [0001] The invention belongs to the field of pollution control, in particular to a method and device for washing pollutants in gas and heat and mass transfer. Background technique [0002] With the rapid development of domestic industry, the problem of air pollution is becoming more and more severe. In recent years, severe smog has frequently appeared in some areas of the country, which has brought a greater threat to the health of urban residents and caused panic and widespread concern among citizens. Inhalable Particulate matter is the chief culprit of this problem and is the primary pollutant of urban air pollution in our country. Inhalable particulate matter is easy to carry heavy metal particles and chemical carcinogens due to its large specific surface area, and its small particle size results in low removal efficiency. Combustion of coal, oil, gas and other fuels and solid waste There are a large number of inhalable particulate matter in the gaseous p...
