Abstract
The utility model relates to a sulphuric acid evaporator, which comprises an evaporator casing and a heat exchanger positioned at the inner lower part of the evaporator casing. The sulfuric acid evaporator is characterized in that the heat exchanger comprises a heating tube, a distance sink tube, a first tube plate, a second tube plate, a deflecting plate, a fixed rod, a steam inlet tube, a steam outlet tube and a cover plate. The sulfuric acid evaporator solves that diluted sulfuric acid of 20% to 70 % is concentrated into finished product acid of more than 90 %. The utility model has the characteristics of high evaporation efficiency, low energy consumption and corrosion resistance.
Description
Technical field
The utility model relates to a kind of sulfuric acid evaporator, and the method that is applicable to vacuum concentration is concentrated into finished acid more than 90% with the dilute sulphuric acid of 20%-70% through heating evaporation.
Background technology
Interchanger generally comprises heater assembly and evaporator room two portions, and the pattern of vaporizer has varied, but all can not solve dilute sulphuric acid etching problem at high temperature.Thereby to use maximum be to adopt iron pan as vaporizer.Heating component is with fire coal or fuel oil direct heating, so iron pan is exactly the direct evaporation chamber.Can produce a large amount of ferric sulfate in this vaporizer operational process, cause iron pan to damage, stop up process system, simultaneously energy consumption height, also contaminate environment.
Summary of the invention
The purpose of this utility model is to have proposed a kind of vaporization efficiency height, low, the corrosion resistant sulfuric acid evaporator of energy consumption at above-mentioned deficiency.
The above-mentioned purpose order is achieved through the following technical solutions.
A kind of sulfuric acid evaporator comprises
Evaporator shell-top has the horizontal enamel still that two interfaces and two ends are respectively equipped with interface, and is supported on the ground with leg;
Interchanger-the be positioned at bottom of evaporator shell;
It is characterized in that interchanger comprises following parts:
Steam inlet pipe-its quantity is two, lays respectively at the top and the bottom of the air chamber of evaporator shell one end;
Steam outlet pipe-the be positioned at bottom that evaporator shell one brings out steam chest;
Cover plate-be 16MnR, be positioned at an end of evaporator shell one end air chamber, and weld mutually with the shell of inlet plenum.
Heating tube-its structure is the tantalum pipe that finger-type is arranged, what be built-in with logical steam at the tantalum pipe leaves the stainless steel tube or the carbon steel pipe in gap with tantalum pipe bottom, steam is come out from the gap of stainless steel tube or carbon steel pipe and tantalum pipe, and forming in the tantalum pipe is heating steam, and the tantalum pipe is outward a dilute sulphuric acid;
Spacing tube-be polyfluortetraethylene pipe, its quantity is two groups, lays respectively at the upper and lower of the heating tube of finger-type arrangement;
First tube sheet-be provided with the hole of inserting heating tube thereon is connected by the interface of bolt with evaporator shell one end;
Second tube sheet-be provided with the hole of the stainless steel tube of inserting logical steam thereon, between inlet plenum and discharge chamber;
Traverse baffle-be polyfluortetraethylene plate, support heating tube and spacing tube, its quantity is 3-4, is provided with the hole of inserting heating tube and spacing tube on its plate, and is provided with flow-guiding mouth;
Fixed link-be polytetrafluoroethylmaterial material, its quantity are 1-2, its underpart respectively with intermediary traverse baffle Joint, its upper end and evaporator shell Joint.
A kind of sulfuric acid evaporator according to claim 1 is characterized in that first tube sheet is tantalum/stainless steel clad plate.
The utility model has solved dilute sulphuric acid with 20%-70% and has been concentrated into finished acid more than 90%, has the vaporization efficiency height, and energy consumption is low, corrosion resistant characteristics; Environmental pollution improves.
