High-voltage pulse electric field sterilizing device for aquaculture

Abstract

The invention discloses a high-voltage pulse electric field sterilizing device for aquaculture. The high-voltage pulse electric field sterilizing device comprises a water treatment chamber for communicating a first water storage tank and a second water storage tank, wherein a water pump is arranged between the first water storage tank and the water treatment chamber; the water treatment chamber is provided with a high-voltage pulse circuit; the high-voltage pulse circuit comprises a high-voltage pulse generator connected with a power source and a pulse treatment vessel; the pulse treatment vessel comprises an earth electrode plate and a high-voltage electrode plate connected with the high-voltage pulse generator; and a channel allowing a water flow to pass through is arranged between the earth electrode plate and the high-voltage electrode plate. The high-voltage pulse electric field sterilizing device is mainly applied to spawn incubation in the aquatic product field and aquaculture water of aquaculture ponds of adult fishes of famous-quality fishes and special fishes and adult shrimp raising ponds, can rapidly achieve the aims of sterilizing, insect killing and alga removal of water in the ponds through the matching of the water pump and the pulse treatment vessel and is wide in application range because of adapting to the existing different ranges and kinds of aquaculture.

Description

technical field [0001] The invention relates to a high-voltage pulse electric field sterilizing device for aquaculture, in particular to a high-voltage pulse electric field sterilizing device for sterilizing and eliminating harm in pond water such as fish egg hatching and adult fish breeding in the field of aquatic products, and belongs to the field of water treatment equipment. Background technique [0002] In the aquaculture system of the existing circulating water model, fish excrement and bait residues will inevitably be produced in the aquaculture water body, and there are a large number of microorganisms and harmful substances. The traditional treatment method is to put them into the aquaculture water body Disinfectant, because the disinfectant itself is toxic, and the toxicity will be enriched in the body of aquatic products, it will cause harm to human health. At present, with the increasing improvement of my country's industrial wastewater treatment technology, in o...

[0003] Patent document CN103588258A (a sterilizing system for aquaculture, 2014.02.19) discloses a sterilizing system that integrates at least one of an ion generator, a high-voltage pulse generator or an ultraviolet generator and can improve the aquaculture environment. The range of action of the system is small, therefore, the bactericidal effect is not ideal

[0004] Patent document CN101147613 (High-voltage pulse electric field sterilization treatment device for liquid food, 2008.03.26) discloses a treatment device that can sterilize liquid food with high-voltage pulse electric field, which solves the high cost and technical difficulty of the existing high-voltage pulse electric field sterilization device Large size and unreasonable structure of the sterilization chamber. However, due to the different composition of the bacterial populations that need to be killed in the existing aquaculture and food, the required sterilization effects are different. The parameters that need to be considered in the design are: pulse amplitude, pulse The cycle, number of pulses, and pulse frequency are all different, so it is not suitable for the sterilization treatment of existing aquaculture
