The device is provided with a heating block, the temperature sensor and a control panel, so that a temperature control function of the device is achieved, functions of the device are enriched, and various treatment requirements of users are met.

Description

technical field [0001] The invention relates to the technical field of catalyst treatment, in particular to a recovery and treatment device for nickel-containing waste catalyst. Background technique [0002] With the development of the country's economy and the advancement of science and technology, people's research on chemistry has become more and more in-depth, and correspondingly more and more chemical catalysts have been used. Nickel-based catalysts generally refer to Raney nickel and Raney nickel. A solid heterogeneous catalyst composed of fine grains of nickel-aluminum alloy with a porous structure. It was first used by American engineer Raney as a catalyst in the hydrogenation process of vegetable oil. The preparation process is to use nickel-aluminum alloy with Concentrated sodium hydroxide solution treatment, in this process, most of the aluminum will react with sodium hydroxide and dissolve, leaving a very dry activated Raney nickel with micropores of different si...

[0002] With the development of the country's economy and the advancement of science and technology, people's research on chemistry has become more and more in-depth, and correspondingly more and more chemical catalysts have been used. Nickel-based catalysts generally refer to Raney nickel and Raney nickel. A solid heterogeneous catalyst composed of fine grains of nickel-aluminum alloy with a porous structure. It was first used by American engineer Raney as a catalyst in the hydrogenation process of vegetable oil. The preparation process is to use nickel-aluminum alloy with Concentrated sodium hydroxide solution treatment, in this process, most of the aluminum will react with sodium hydroxide and dissolve, leaving a very dry activated Raney nickel with micropores of different sizes, so that Nickel is a fine gray powder on the surface, but from a microscopic point of view, each tiny particle in the powder is a three-dimensional porous structure, which greatly increases its surface area, which brings great benefits. High catalytic activity, which makes Raney nickel widely used as a heterogeneous catalyst in the hydrogenation reaction of organic synthesis and industrial production. After these catalysts are used, if they are discharged randomly, they will cause serious environmental pollution. In addition, These catalysts often contain more usable components inside. In response to these problems, in order to better implement environmental protection and energy saving, we have proposed a new type of nickel-containing waste catalyst recovery and treatment device to better meet the needs of the market.
