Process and apparatus for implementing automatic stirring by using self-energy of chemical reaction

Abstract

The invention belongs to ta process and apparatus for implementing automatic stirring by using self-energy of a chemical reaction, comprising a lower reactor. The lower reactor is connected with an upper reactor through a rise pipe, a joint of the rise pipe and the reactor is tangent to a tubular wall of the reactor, a central barrel with a downward opening is welded to the top end of the reactor and used for collecting clear liquid produced by a reaction; stirring is achieved through a pressure difference between level difference of the upper and lower reactors and a density difference between fluids in the rise pipe and a down pipe; the upper reactor is connected with the lower reactor through the down pipe and is used for charging concentrate into the lower reactor for stirring; an outer circular top gas outlet of the upper reactor is connected sequentially with a defroster and a condenser and is used for collecting condensate, non-condensable gas is liquid sealed and discharged or fed for post-treatment. The whole system makes full use of characteristics of the apparatus so as to stir the materials, with no extra stirring equipment required; it is also possible to recycle concentrate and clear liquid, secondarily utilize the condensate, effectively reducing production cost.

Description

technical field [0001] The invention belongs to a chemical process device, specifically a process and a device for realizing automatic stirring by utilizing the energy of the chemical reaction itself. Background technique [0002] For the leaching of metals (and alloys) and other bulk or granular materials, most of them are first refined (atomized or milled) to facilitate stirring and leaching. Tank”; other pressure reaction equipment (especially pressure reaction equipment with high requirements for corrosion resistance) is difficult to manufacture the stirring device, and the dynamic sealing part is expensive and fragile. In engineering, a large number of chemical reactions are exothermic reactions that often need to be cooled, which wastes the heat of reaction and the energy of gas generated by the reaction. Contents of the invention [0003] The purpose of the present invention is to provide a simple and economical process and device, which uses the fluid density diff...
