Problems solved by technology

However, in the process of treating organic waste gas by the biological trickling filtration method in the prior art, due to the insoluble volatile organic compounds, the mass transfer effect between the gas-liquid phase is poor, the utilization rate of the filler is low, and the processing capacity of the biological purification system is not fully utilized, so the enhanced gas The mass transfer of volatile organic compounds between liquid phases can improve the treatment effect of biological trickling filter towers on volatile organic compounds

Embodiment 1

[0031] refer to figure 1 , this embodiment provides a gas-liquid mass transfer tank 107 , including: a tank body 102 , an inlet pipe 109 , a Venturi tube 111 , a liquid inlet pipe 119 , and a delivery pump 137 .

[0032] In this embodiment, the inside of the tank body 102 has a cavity for containing the working fluid, and the cavity is divided into a first space 123 and a second space 125 by the working fluid. The working liquid is placed in the second space 125 .

[0033]Among them, the working liquid can be various liquids used to treat exhaust gas, and further can be a mixed aqueous solution of non-ionic surfactant Tween 80 with nutrients added and solubilized. The added nutrients are available for microorganisms What is required for growth, the addition of surfactants can also increase the mutual solubility effect between gas and liquid, thereby also enhancing the gas-liquid mass transfer effect accordingly.

[0034] In this example, see figure 1 and figure 2 , the nu...

Abstract

The invention provides a gas-liquid mass transfer box and a bio-trickling filter and belongs to the technical field of volatile organic compound control. The gas-liquid mass transfer box comprises a box body, a gas inlet pipe for conveying working gas, a Venturi tube, a liquid inlet pipe and a conveying pump for pumping working liquid. The liquid inlet pipe is connected with the conveying pump in a matched mode. The gas inlet pipe, the liquid inlet pipe and the Venturi tube communicate with one another in the box body. Gas and liquid are sufficiently mixed according to the working principle of the Venturi tube, and the mass transfer effect of organic waste gas is improved. The bio-trickling filter comprises a filter body, a spraying system and the gas-liquid mass transfer box. The filter body is provided with a liquid storage section, a gas distribution section and a filler section for fixing filler, and the liquid storage section, the gas distribution section and the filler section are connected in sequence. The gas-liquid mass transfer box is connected with the gas distribution section through a pipeline. The bio-trickling filter sufficiently utilizes the mass transfer effect of the gas-liquid mass transfer box, and the treatment capacity of a biological purification system is brought into play efficiently.

Description

technical field [0001] The invention relates to the technical field of volatile organic compounds treatment, in particular to a gas-liquid mass transfer box and a biological trickling filter tower. Background technique [0002] With the rapid development of electronics, energy, chemical industry, medicine and other industries, more and more pollutants enter the atmosphere. Volatile Organic Compounds (VOCS) in petrochemical, paint, printing and other industrial production processes, as well as malodorous exhaust gas produced in sealable areas such as organic solvent sewage treatment plants, animal husbandry plants and landfills. There are many kinds of volatile organic compounds and they are widely distributed. Since most VOCs are toxic, odorous, and some have carcinogenic effects, organic waste gas pollution can undergo photochemical reactions with nitrogen oxides and hydrocarbons under sunlight, and halocarbon VOCs can be The destruction of the ozone layer has become anoth...
