Problems solved by technology

[0003] At present, in chemical reactions, by-products may be corrosive acids or alkalis, and there is no corrosion-resistant reaction device that can transfer by-products while converting reactants into products; with the development of metallurgy and chemical technology, many production The process requires the transfer of by-products as soon as possible to realize the integration of reaction and separation, which is convenient for engineering strengthening; this requires the corresponding reaction device to be able to withstand high temperature and high pressure, and to be able to resist corrosion and transfer by-products under these conditions, so as to achieve a high conversion rate of reactants , high yield of products and zero discharge of waste liquid; and the existing reactor has no corresponding technical means to realize the formation of reactants and transfer of by-products under high temperature, high pressure and corrosive conditions

Abstract

The invention discloses an anti-corrosion and high-temperature-resistant reaction device integrating reaction and separation, which comprises a reaction kettle body, an anti-corrosion layer, a bracket, a reactant container, a separation aid box, a condensation conical frustum, a sealing gasket and a reaction kettle cover; Additional feed pipes for reactants, auxiliary agent input pipes, coolant inlet pipes, coolant outlet pipes, auxiliary agent vent pipes and product outlet pipes are added; among them, the condensate conical frustum is pre-embedded with a coil cooling structure, and the separation aid The outer bottom of the kit is an upward convex structure. This device can be used under the conditions of strong acid, strong alkali medium, high temperature and high pressure. The by-products are transferred and transformed, which reduces the reaction resistance and improves the conversion rate of materials in the kettle. , the product yield is high, the mother liquor is directly used for the next batch of synthesis, the reaction and separation are carried out simultaneously, the separation process does not need to consume additional transportation and heating energy, no need to build special separation equipment, energy saving, space saving, simple process, Economical and reasonable, conducive to engineering strengthening.

Description

technical field [0001] The invention relates to an anti-corrosion and high-temperature-resistant reaction device for reaction and separation, in particular to an anti-corrosion and high-temperature-resistant reaction device for reaction and separation in metallurgical and chemical industries. Background technique [0002] The reaction devices used in the metallurgical and chemical industries generally require a higher conversion rate of reactants. In addition to stirring, it is generally achieved by using a large amount of solvent, increasing the reaction temperature, prolonging the reaction time, adding reaction aids or catalysts, etc. ;Taking the hydrothermal synthesis material carried out in the reactor as an example, for the reaction process with by-product generation, add a large amount of solvent to dissolve the reactant, so as to mix uniformly and follow-up synthesis reaction; there is an upper limit for increasing the reaction temperature, and Other by-products will ...
