Disinfector mixing device for supplementing residual chloride between pipe networks

Abstract

The invention relates to a water treatment device between pipe networks, particularly discloses a disinfector mixing device for supplementing residual chloride between the pipe networks and solves the problem of an existing mixer that a drug mixing effect cannot be met and head loss exists. The disinfector mixing device is characterized in that multiple flow diversion blades are fixedly arranged on the inner wall of a water transmission pipe; the front sections of the flow diversion blades are parallel to the axis of the water transmission pipe, and the rear sections are twisted along the same direction of the circumference of the water transmission pipe; the number of the flow diversion blades is 3 to 4; the total length of the flow diversion blades is 2 to 4 times the inner diameter of a pipe; the length of the front sections of the flow diversion blades is 0.2 to 0.5 time the total length of the flow diversion blades; a ratio of the height of the flow diversion blades to the inner diameter of the pipe is 0.3 to 0.35; a twisting angle is 30 to 40 degrees. The disinfector mixing device disclosed by the invention has the advantages that the flow diversion blades are arranged to form a circular blade cascade along the pipe wall, the middle part of the circular blade cascade is hollow, fluid in an outer ring is changed from a straight flowing state into a spiral flowing state, and the fluid is kept in spiral motion within a certain length after the fluid flows out of a water opening; drugs can be fully mixed by utilizing a spiral flow property; the number and the occupied flow choking area of mixing elements are reduced, and energy loss of water flow is reduced.

Description

technical field [0001] The invention relates to a water treatment device between pipe networks, in particular to a disinfectant mixing device for supplementing residual chlorine between pipe networks. Background technique [0002] The safety of water supply quality is an important issue related to human health and social stability. In order to ensure the water quality of the pipe network, the "Drinking Water Hygienic Standard" (GB5749-2006) clearly stipulates that during chlorine disinfection, after free chlorine is in contact with water for more than 30 minutes, the concentration of residual chlorine at the factory should not be less than 0.3mg / L. The water at the end of the pipe network should not be lower than 0.05mg / L. At present, the disinfection of most water plants is to add enough chlorine to the clean water tank at the front end of the pipe network at one time to ensure that the residual chlorine at the end of the pipe network reaches the standard. However, due to...
