Reaction kettle prepared from active tantalum metal, active zirconium metal, active titanium metal and low-alloy-steel composite plate

Abstract

The invention discloses a reaction kettle prepared from active tantalum metal, active zirconium metal, active titanium metal and a low-alloy-steel composite plate. The reaction kettle comprises a first cylinder body, wherein the top of the first cylinder body is fixedly connected with an upper seal head, the left side of the top of the upper seal head is communicated with a material inlet, the interior of a stirring port is rotatably communicated with a transmission device, and a shaft seal device is fixedly connected in the stirring port; the inner wall of the shaft seal device is rotatably connected with the transmission device. According to the reaction kettle prepared from the active tantalum metal, the active zirconium metal, the active titanium metal and the low-alloy-steel compositeplate, zonal corrosion resistance is effectively achieved, the cost is reduced, the integral use effect of equipment is ensured, and effective zonal material selection is achieved; a zirconium material is applied to a contact medium part of a stirring device according to medium corrosion properties and the corrosion resistance requirements of materials, a baffle assembly is used as the main partof the stirring device, and a supporting-type stirring design structure is selected, so that the reaction effectiveness of each section is ensured, and the effective and reliable reaction functions ofa reactor are guaranteed.

Description

technical field [0001] The invention relates to the technical field of reaction kettles, in particular to a reaction kettle prepared by active metals such as tantalum, zirconium and titanium and low-alloy steel composite plates. Background technique [0002] In the equipment of fine chemical equipment, the reactor, as a key production equipment, needs to withstand the corrosion of raw materials and reaction media while under high temperature, high pressure and other conditions. Due to changes in chemical production products, reaction processes, raw materials, and reaction conditions, Reactor product structure and corrosion resistance requirements are completely different. Due to the corrosiveness of the medium, low alloy steel materials, stainless steel, etc., are easily corroded during use, causing leakage or even safety accidents, endangering life safety. Active metals such as tantalum and zirconium materials have Good corrosion resistance. However, tantalum, zirconium, an...

[0002] In the equipment of fine chemical equipment, the reactor, as a key production equipment, needs to withstand the corrosion of raw materials and reaction media while under high temperature, high pressure and other conditions. Due to changes in chemical production products, reaction processes, raw materials, and reaction conditions, Reactor product structure and corrosion resistance requirements are completely different. Due to the corrosiveness of the medium, low alloy steel materials, stainless steel, etc., are easily corroded during use, causing leakage or even safety accidents, endangering life safety. Active metals such as tantalum and zirconium materials have Good corrosion resistance. However, tantalum, zirconium, and titanium are expensive. If the entire equipment is made of tantalum, zirconium, and titanium, the manufacturing cost will be high
