Environment-friendly efficient boiler deoxidant

The invention discloses an environment-friendly efficient boiler deoxidant which is prepared from the following raw materials in parts by weight: 20-25 parts of dimethyl ketoxime, 13-18 parts of diacetylmonoxime, 10-12 parts of acetaldoxime, 12-17 parts of carbazide, 6-10 parts of a dispersing agent, 5-10 parts of a pH regulator, 3-7 parts of a catalyst and 30-40 parts of purified water. And the used oxime raw materials such as dimethyl ketoxime, diacetylmonoxime and acetaldoxime have relatively strong reducibility, have the characteristics of low toxicity, high efficiency and high speed in the aspect of oxygen removal, and play a role in passivation protection on the surface of the boiler. And meanwhile, the stability is high, and a good oxygen removal function is achieved within a wide temperature and pressure range. The three substances are mixed with carbazide which also has a deoxidizing effect to enhance the deoxidizing capability, and meanwhile, the dispersing agent, the catalyst and the pH regulator a
