Abstract
Graphitic synthetic furnace described in the utility model, stove cylinder shell is made up of two graphite linings material, is divided into being interconnected successively from bottom to top: synthesis stage, cooling section, absorber portion and upper cover.Cooling section is jacket structured, and chuck lower end is communicated with cold water inlet, and upper end is communicated with vapour outlet.Steel urceolus or stirrup can be also had, to strengthen casing rigidity outside described synthesis stage and the housing of cooling section.Synthetic furnace housing erosion resistance of the present utility model is strong, and resistance to compression impact resistance intensity is high, high insulating effect, the long perfomance life of synthetic furnace.
Description
Technical field
The utility model relates to a kind of hydrochloric acid synthetic furnace, particularly relates to a kind of hydrochloric acid synthetic furnace that can improve synthetic furnace body of heater compressive strength and heat insulation effect.
Background technology
Traditional HCL, SO
2, N
2, the burst strength of synthetic tower tower body that adopts in the compound probability such as dimethylbenzene is on the low side, insulation effect is not good enough, and security incident is more, and energy consumption is larger.
Application number be 2012104937461 invention provide a kind of hydrochloric acid synthetic furnace of water cooled wall type graphite furnace cylinder, cooling-part comprises stove cylinder, water inlet pipe, steam outlet pipe.Graphite furnace cylinder is spliced by polylith graphite circle, each graphite circle after resol double-steeping through 130 DEG C of-380 DEG C of pyroprocessing.The joint flange of stove cylinder and water inlet pipe, steam outlet pipe is that high temperature steel is made, and the furnace shell of compound component and absorption piece is that carbon steel is made.Splicing seams between two graphite circles is tongue and groove shape; Splicing seams adopts the cementing connection of resol, through the solidification treatment of 130 DEG C of-240 DEG C of temperature after cementing.The poor-performing of the resistance to internal gas pressure of this stove cylinder shell and external impact.
Summary of the invention
Utility model object: the utility model provides the graphitic synthetic furnace for fields such as hydrochloric acid synthesis that a kind of burst strength is high, insulation effect is good.
Technical scheme:
Graphitic synthetic furnace described in the utility model, is divided into and is interconnected successively from bottom to top: synthesis stage, cooling section, absorber portion and upper cover, stove cylinder shell is made up of two graphite linings material.Two graphite linings material refers to that internal layer is graphite linings, and skin is soft graphite layer, and materials at two layers fits tightly together.The internal layer of cooling section is wherein jacket structured, and chuck lower end is communicated with cold water inlet, and upper end is communicated with vapour outlet.
During fabrication, between described graphite linings and soft graphite layer, be added with the adhesivess such as resistant to elevated temperatures Phenol aldehyde resin, and can be passed through the process that is heating and curing.
Described graphite linings is respective independently segmentation structure at described synthesis stage, cooling section, absorber portion and upper cover, then fits together, is convenient to making and installation; And soft graphite layer surrounds structure (pipeline locally, valve or instrument connector place can leave small-sized perforate or fluting) for the entirety be connected, make body of heater Integral sealing effective, high insulating effect.
Described synthesis stage and cooling section; press larger in bearing because internal temperature is higher; position is lower easily to be touched by boundary's object by mistake; soft graphite layer also has steel urceolus or stirrup outward; to protect soft graphite layer; strengthen bulk strength, be convenient to be fixedly connected with the ground of production plant or other facility.
The utility model is used for principle of work during hydrochloric acid synthesis:
Hydrogen and chlorine enter synthesis stage, synthesizing chlorinated hydrogen in synthesis stage; High-temp chlorination hydrogen rises, and enter cooling section, a part of combustion heat passes to water coolant in synthesis stage and cooling section by stove cylinder and interchanger, and then the combustion heat is converted to the heat content of water; Directly can make thermal water utilization after output furnace cylinder, or become saturated vapor utilization.Hydrogen chloride gas after cooling continues to rise, and enters absorber portion, and while absorber portion rises, absorbed by the absorption liquid (water) flowed from top to bottom, absorption liquid acid concentration is enhanced; The absorption liquid being enhanced concentration flows downward, and exports output by concentrated hydrochloric acid; Another part gas continues to rise, and discharges outside body of heater carry out later stage recycling with tail gas form.
Beneficial effect: synthetic furnace inwall erosion resistance of the present utility model is strong, and because soft graphite has snappiness, bilayer structure makes it can tolerate the high pressure of internal gas, the intensity of tolerance external impact collision is high.Due to a large amount of reaction heat that building-up reactions produces, can byproduct steam, the adiabatic heat insulating effect of Whole Equipment is good, isothermal holding that substantially need not be extra.Fully can reclaim thermal source, reduce the disadvantageous effect to workshop condition, and speed of response and combined coefficient can be improved.The steel urceolus that the outer local of bilayer structure adopts or stirrup, can either protect soft graphite layer, strengthen bulk strength further, facilitates again the ground of equipment and production plant or other facility to be fixedly connected with, guarantee device security, extension device work-ing life.
