Abstract
A reactor for preventing degradation reaction aims to solve the problems that an inside coating of an existing reactor is provided with baked enamel and sprayed polytetrafluoroethylene, and when the coating is damaged, iron ions on the tank skin of the existing reactor lead to chemical degradation of polyacrylamide gel, so that the polyacrylamide gel with reduced molecular weight loses mechanical strength. The reactor for preventing degradation reaction comprises a tank (1), a metal alloy coating (2) is sprayed on the inner wall of the tank (1), and a coating layer (3) is sprayed on the outer side of the metal alloy coating (2). The reactor for preventing degradation reaction is mainly used for producing polyacrylamide.
Description
Technical field
The utility model relates to a kind of agitated reactor.
Background technology
The material that the agitated reactor of polyacrylamide colloid is housed is generally carbon steel; Because the polyacrylamide viscosity that reaction generates is very big; Therefore; Need on the agitated reactor inwall, brush and have and the sticking materials with function of polyacrylamide, prevent polyacrylamide colloid wall built-up after being pushed out agitated reactor, cause discharging not smooth.Existing agitated reactor inside coating has roasting enamel and spray to gather tetrafluoro; The sticking characteristic of wherein gathering tetrafluoro is best, but can't field patch after its damages the same with enamel, and enamel needs the W-response still to transport sintering again back; Gather the tetrafluoro coating in case damage, when receiving external force, can become to open into opening.When coating is damaged; When if the agitated reactor tank skin is carbon steel material; Iron ion can cause the polyacrylamide colloid chemical degradation, makes the polyacrylamide colloid molecular weight and molecular weight, the forfeiture mechanical strength; The inefficacy polyacrylamide colloid lump that is bonded on the tank skin increases gradually, coating well damage when receiving thrust.Many and time of polyacrylamide colloid on being bonded at the agitated reactor tank skin can make the quality of the polyacrylamide colloid that generates with afterreaction descend when long, and influence is produced.
The utility model content
The purpose of the utility model is to have roasting enamel and spray to gather tetrafluoro for solving existing agitated reactor inside coating; When coating is damaged; The iron ion of agitated reactor tank skin can cause the polyacrylamide colloid chemical degradation; Make the polyacrylamide colloid molecular weight and molecular weight, the problem of forfeiture mechanical strength provides a kind of agitated reactor that prevents degradation reaction.
The utility model comprises tank body, and the inner-wall spraying of said tank body has metal alloy coating, and the outside of said metal alloy coating is coated with dope layer.
The utility model has the advantages that: the utility model spray metal alloy coat is the characteristic that changes the stainless steel metal alloy for the tank body material characteristic that makes carbon steel into; Avoid the material (iron ion) of tank body that the polyacrylamide colloid in the tank body is produced degradation; When the dope layer local damage; Metal alloy coating plays insulating effect, thereby makes polyacrylamide colloid can not produce degradation reaction with mother metal (carbon steel tank skin), and the dope layer of local damage can not continue to enlarge.Dope layer 3 has gasproof erosion, ageing-resistant, characteristics that wearability is high.
Description of drawings
Fig. 1 is the overall structure front view of the utility model, and Fig. 2 is the I partial enlarged drawing of Fig. 1.
The specific embodiment
The specific embodiment one: combine Fig. 1 and Fig. 2 that this embodiment is described, this embodiment comprises tank body 1, and the inner-wall spraying of tank body 1 has metal alloy coating 2, and the outside of said metal alloy coating 2 is coated with dope layer 3.Metal alloy coating layer 2 using nickel-chromium-nickel alloy (NiCrNiAi) materials, nickel-chromium-nickel alloy coating and the steel has good adhesion, but also has a certain toughness, steel equipment to adapt to the deformation of the normal range, heat swelling shrinkage does not occur under such circumstances Alice skin, shell, nickel-chromium-nickel alloy coating has a certain impact and abrasion, as spray coating pores large, interconnected pores, and extending from the surface to the substrate, reducing protective effect of the covering layer covering the non-stick coating layer was closed, the porosity rate is reduced, improving the corrosion resistance, wear resistance, on the other hand as nickel-aluminum-nickel-chromium alloy spray coating the surface of the base material so that the anchor effects increase, brush coating layer 3 of the bonding strength increases.The effect of dope layer 3 is that polyacrylamide colloid that tank body 1 internal reaction is generated flows out agitated reactor and hanging pot wall not smoothly under the pressure of 0.4mp.Dope layer 3 adopts nano-macromolecule material, and nano-macromolecule material is made up of nano-ceramic powder and curing agent, and curing agent is made up of fluororesin, polyurethane, phenolic aldehyde and acrylic acid etc.
The specific embodiment two: combine Fig. 2 that this embodiment is described, the thickness of the metal alloy coating 2 of this embodiment is 0.15mm～0.3mm.Other composition is identical with the specific embodiment one with annexation.
The specific embodiment three: combine Fig. 2 that this embodiment is described, the thickness of the dope layer 3 of this embodiment is 0.15mm～0.3mm.Other composition is identical with the specific embodiment one or two with annexation.
Claims (3)
