Multitube-structure ozone generator and manufacture method thereof

Abstract

The invention discloses a multitube-structure ozone generator and a manufacture method thereof. The multitube-structure ozone generator overcomes problems in prior arts that ozone yield is low, a demand of treating a large amount of wastewater is not met and welding deformation cannot be controlled through conventional manufacture methods. The multitube-structure ozone generator is characterized by comprising a supporting frame of heat conversion tubes, and the supporting frame consists of fixed pulling rods, an upper tube sheet, a lower tube sheet and baffle plates; more than 1000 heat conversion tubes are inserted into the supporting frame from heat conversion tube holes in the upper tube sheet, pass through heat conversion tube holes in the shell-side baffle plates, and extend out through heat conversion tube holes in the lower tube sheet; and a high-voltage discharge tube is inserted into a bottom orifice of each heat conversion tube. The manufacture method comprises performing numerical-control drilling, performing numerical-control match drilling, performing vertical assembling, threading the heat conversion tubes, assembling an anti-deformation tool, and performing welding sealing on the heat conversion tubes with the upper tube sheet and the lower tube sheet. The beneficial effects comprise that the multitube-structure ozone generator exerts stabilizing and supporting effects on the 1104 high-voltage discharge tubes in terms of structures and has a good cooling effect, the manufacture method is employed for strictly controlling the welding deformation and ensuring the assembly requirements of the high-voltage discharge tubes and the heat conversion tubes after welding, and the demand of treating a large amount of wastewater is met.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, and particularly relates to an ozone generator and a manufacturing method thereof, more specifically to a multi-tube structure ozone generator and a manufacturing method thereof which use oxygen to generate ozone through a high-voltage discharge tube reaction. Background technique [0002] Ozone is an allotrope of oxygen. Under normal temperature, normal state and normal pressure, the lower concentration of ozone is a colorless gas. When the concentration reaches 15%, it appears light blue. Ozone is soluble in water. At normal temperature and normal pressure, the solubility of ozone in water is about 13 times higher than that of oxygen and 25 times higher than that of air. Ozone is a strong oxidant, which can destroy and decompose the cell wall of bacteria, destroy the metabolism and reproduction process of bacteria, and can also oxidize and decompose pollutants in water. , cy...
