Abstract

The invention relates to a multi-section vertical variable diameter guide cylinder central air-lift loop reactor, belonging to the field of high-concentration industrial waste water treatment equipment. Comprises an outer cylinder, a variable diameter guide cylinder and an inverted U-shaped tube pressure gauge, wherein the two openings of the inverted U-shaped tube pressure gauge are respectivelycommunicated with the upper end opening and the lower end opening of the outer cylinder; a plurality of variable diameter guide cylinders are vertically arranged in the outer cylinder; the smaller endof the variable diameter guide cylinder is upward; a microplate is arranged below the larger end of the variable diameter guide cylinder; and a sewage inlet is arranged at the bottom of the outer cylinder. The structure and combination of the outer cylinder, the microplate and the variable diameter guide cylinder can improve the mixing effect, increase the coalescence and crushing efficiency of bubbles, increase the gas content and further improve the overall reaction efficiency; At the same time, the invention occupies a small area and saves space.

Description

technical field [0001] The invention relates to the field of high-concentration industrial wastewater treatment equipment, in particular to a multi-segment vertical variable-diameter guide cylinder central airlift loop reactor. Background technique [0002] With the rapid development of the brewing industry and the improvement of human living standards, the production and sales of wine, sauce and vinegar have increased significantly. While consuming a large amount of food, the discharge of brewing industrial wastewater will inevitably increase, so the environmental problems brought about are becoming more and more serious; In the brewing industry, wine accounts for the largest proportion. Wine is produced with water as the medium, and a large amount of cleaning water and process water are required in the brewing process. The beer industry is the most water-consuming industry, and its sewage production accounts for the total water consumption. Beer industry wastewater mainly ...
