Palladium-plating catalyst, preparation method and application in deoxidization of water circulation system

Abstract

The invention discloses a palladium-plating catalyst, a preparation method and application in deoxidization of a water circulation system. The preparation method comprises that: dried ion resin or active carbon is soaked in a 2 to 10 permillage palladium chloride solution for 1 hour for reaction to generate a mixture of which the surface of the resin or the active carbon is plated with palladium, and the mixture is filtered, dried and added with a reducing agent to remove chloride ions in the mixture; the mixture is repeatedly soaked by pure water and dehydrated in circulation until the pH value in the water is 7; and the mixture is filtered and washed by water to control the conductivity of the mixture below 6 mu S / cm, and then filtered to prepare resin or active carbon palladium-plating catalyzing particles. The resin or active carbon palladium-plating catalyzing particles and hydrogen are together added into the water circulation system; and at normal temperature, the hydrogen can be reacted with oxygen in the water to reduce the oxygen content in the water, so that the water is recycled under the condition of no oxygen, the service life of equipment can be prolonged, the maintenance period is reduced, the economic benefit is improved, and the water is not polluted at the same time.

Description

technical field [0001] The invention relates to a deoxygenation technology of a water circulation system, in particular to a palladium-plated catalyst and its preparation method and its application in the deoxidation of a water circulation system. Background technique [0002] In the prior art, water circulation systems, especially closed water circulation systems, are widely used in industrial and agricultural production and people's lives. For example, in the cooling system of large generators, or in the cooling system of other electromechanical equipment, water is a good cooling medium, cheap and non-toxic, non-combustible, no explosion hazard, and has unparalleled advantages compared to other cooling media. [0003] Above-mentioned prior art has following shortcoming at least: [0004] Metals are easily oxidized by oxygen ions in water, producing oxides that cause adverse consequences such as blockage of waterways, increase maintenance costs, and shorten the service lif...
