Problems solved by technology
The inner wall of the traditional washing liquid nozzle is equipped with swirl parts to achieve gas-liquid two-phase collision, thereby achieving efficient mass transfer. However, when the operating conditions change, due to the fixed form of the internal swirl parts, the coverage and momentum of the liquid flow at the outlet of the nozzle Cannot be adjusted accordingly, which affects the mass transfer effect and ultimately leads to low efficiency of sulfur dioxide flue gas scrubbing

The invention relates to a gas-liquid countercurrent contact scrubber, and belongs to the industrial technical field. The technical problem to be solved by the invention comprises that the mass transfer effect of a conventional scrubber is poor and low scrubbing efficiency of sulfur dioxide flue gas is ultimately caused. According to the technical scheme, the gas-liquid countercurrent contact scrubber comprises an oxygen bottle, a dissolved oxygen tank, an oxygen distributor, a water pump, a reverse-jet scrubbing pipe, a nozzle, a waste water recovery tank and a demister; the oxygen distributor is arranged at the bottom of the dissolved oxygen tank; a gas outlet of the oxygen bottle is connected with the oxygen distributor through a pipeline; the nozzle is arranged in the middle of the reverse-jet scrubbing pipe, a water inlet end of the water pump is extended into the dissolved oxygen tank, a water outlet end of the water pump is connected with the nozzle, one end of the reverse-jet scrubbing pipe is extended into the bottom of the waste water recovery tank, and the upper part of the waste water recovery tank is provided with the demister. The gas-liquid countercurrent contact scrubber has the beneficial effects that the gas-liquid countercurrent contact scrubber has simple structure, and the flue gas scrubbing efficiency is greatly improved by perfect two-section type combination of a rotary jet section and a high-efficiency mass transfer section.
Description
technical field [0001] The invention belongs to the field of industrial technology, and in particular relates to a gas-liquid countercurrent contact scrubber. Background technique [0002] In industrial production processes such as oil refining, chemical industry and electric power, a large amount of sulfur dioxide flue gas will be produced. It is an effective and widely used wet desulfurization method to use "washing liquid" and flue gas countercurrent "impact", among which dynamic wave washing technology is the most representative. The inner wall of the traditional washing liquid nozzle is equipped with swirl parts to achieve gas-liquid two-phase collision, thereby achieving efficient mass transfer. However, when the operating conditions change, due to the fixed form of the internal swirl parts, the coverage and momentum of the liquid flow at the outlet of the nozzle The corresponding adjustments cannot be made, which affects the mass transfer effect and ultimately leads ...
