Abstract
The utility model relates to an energy-saving internal-heating alkali solution purification device. According to the utility model, an elevation device is arranged on a side of a boiler body. The elevation device drives a moving rack positioned above an upper end opening of the boiler body. A heating coil is arranged on the moving tack. The inlet and the outlet of the heating coil communicate with a hot flue gas source. According to the utility model, the moving rack which can elevate vertically is arranged on the upper end of the boiler body; the heating coil is arranged on the moving rack; hot flue gas is delivered in the heating coil; and the heating soil directly extends into the alkali solution and carries out heat exchange with the alkali solution. Heat exchange efficiency is high, evaporation effect is good, and the moving rack can be lifted or lowered automatically so as to be adapted to the level of the alkali solution. With an outer cover arranged on the moving rack, the discharge of evaporated water vapor can be accelerated, such that evaporation effect is improved. The hot flue gas can adopt the tail gas of the combustion of a byproduct hydrogen, such that energy consumption is further saved.
Description
Technical field
The utility model belongs to sodium hydroxide solution evaporation purifying plant, especially a kind ofly adds the heat alkali liquid purifying plant in energy-saving.
Background technology
Alkali factory carries out the volume production of chlorine by a large amount of saturated aqueous common salts of electrolysis, byproduct is sodium hydroxide solution and hydrogen, hydrogen directly burns, and sodium hydroxide solution carries out evaporation process, with recovery NaOH, the more normal Ni-hard pot of this processing procedure, it is directly with straight fire heating, add a small amount of sodium nitrate with oxidation of impurities during heating, and add appropriate sulphur toning.
When above-mentioned Ni-hard pot uses, its bottom surface arranges burning things which may cause a fire disaster, transfer heat to a pot body by burning things which may cause a fire disaster, then pass to solution, constantly make the solvent evaporation, obtain at last melting without water sodium hydroxide, but this mode of heating heat loss is more, causes the thermal efficiency low, and the continuous crystallization of internal wall pot body, affect heat transfer, cause equally the reduction of the thermal efficiency.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides rational in infrastructure, the thermal efficiency is high adds the heat alkali liquid purifying plant in energy-saving.
The technical scheme that the utility model is taked is:
A kind ofly add the heat alkali liquid purifying plant in energy-saving, comprise a pot body, it is characterized in that: a lowering or hoisting gear is installed on limit, pot side, this lowering or hoisting gear drives one and is positioned at the described pot of movable stand above the body upper end open, one heat(ing) coil is installed, the import of this heat(ing) coil and the outlet hot flue gas of connection source on this movable stand.
And described movable stand upper surface spiral-lock one outer cover is installed an extraction fan in the exhaust outlet of this outer cover upper end, uniformly on described movable stand makes a plurality of through holes.
And, described lowering or hoisting gear comprises support, leading screw, screw and motor, described support vertically is arranged on the outer wall of described pot body, leading screw vertically is installed in support, this leading screw is by the motor-driven of support upper end installation, at leading screw outer rim suit screw, the connecting rod that this screw outer rim fills from support near the pot body side surface on made opening stretch out and connect described movable stand.
Advantage of the present utility model and good effect are:
In the utility model, but the movable stand of a vertical lifting is set in pot body upper end, on this movable stand, heat(ing) coil is installed, the hot flue gas of circulation in heat(ing) coil, heat(ing) coil stretches into direct in alkali lye and alkali lye carries out heat exchange, the thermal efficiency is high, evaporation effect is good, but and movable stand automatic-ascending or descend to adapt to the height of alkali lye, the outer cover of installing on movable stand can make the steam of evaporation accelerate to drain, increased the effect of evaporation, hot flue gas can use the tail gas of byproduct combustion of hydrogen, has saved again the consumption of the energy.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment, the utility model is further illustrated, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind ofly add the heat alkali liquid purifying plant in energy-saving, as shown in Figure 1, comprise pot body 11, innovation of the present utility model is: a lowering or hoisting gear is installed on limit, pot side, this lowering or hoisting gear drives one and is positioned at the described pot of movable stand 10 above the body upper end open, one heat(ing) coil 9 is installed, the import 5 of this heat(ing) coil and the outlet hot flue gas of connection source on this movable stand.
In the utility model, described movable stand upper surface is by brace 4 spiral-lock one outer covers 3, and this outer cover upper end exhaust outlet 6 interior installation one extraction fans 7 uniformly on described movable stand are made a plurality of through holes 8.
Lowering or hoisting gear comprises support 2, leading screw 16, screw 15 and motor 1, described support vertically is arranged on the outer wall of described pot body, leading screw vertically is installed in support, this leading screw is by the motor-driven of support upper end installation, at leading screw outer rim suit screw, the connecting rod 13 that this screw outer rim fills from support near the pot body side surface on made opening 14 stretch out and connect described movable stand.
In the utility model, but the movable stand of a vertical lifting is set in pot body upper end, on this movable stand, heat(ing) coil is installed, the hot flue gas of circulation in heat(ing) coil, heat(ing) coil stretch into alkali lye 12 interior directly and alkali lye carry out heat exchange, the thermal efficiency is high, evaporation effect is good, but and movable stand automatic-ascending or descend to adapt to the height of alkali lye, the outer cover of installing on movable stand can make the steam of evaporation accelerate to drain, increased the effect of evaporation, hot flue gas can use the tail gas of byproduct combustion of hydrogen, has saved again the consumption of the energy.
