Abstract
The invention discloses a pressure modulating method and device of desiliconisation machine and self-evaporator system in the alumina manufacturing course, which is characterized by the following: controlling the pressure of desiliconisation machine and self-evaporator system separately; making desiliconisation machine and self-evaporator system non-association; guaranteeing constant pressure by pressure adjustment through two-grade valve; stabilizing the manufacturing course; simplifying the controlling operation; adopting electric or pneumatic valve; saving investment obviously.
Description
Technical field
The present invention relates to a kind of in aluminum oxide production process, the control method and the setting device of desilicator and flash-pot system pressure.
Technical background
In the desiliconizing crude liquid obtained process of existing alumina producing, system pressure in desilicator and the flash-pot is to rely on the variable valve on the flash-pot steam outlet pipe to change, there are the following problems for this control method: desilicator is related with flash-pot pressure, pressure in the desilicator is subjected to the influence of flash-pot, desiliconization pressure transient; The slip amount that enters flash-pot is uncontrollable; Adopt electronic or the Pneumatic pressure adjusting, cost an arm and a leg the cost height.
Summary of the invention
The present invention is exactly for a kind of desilicator that provides and the control method and the setting device of flash-pot system pressure are provided, and its objective is for the variation that alleviates the desilicator pressure that brings owing to the flash-pot pressure transient, has stablized the desilicator operational condition, has guaranteed desiliconization effect.
In order to achieve the above object, the present invention is achieved in that the control method of desilicator and flash-pot system pressure, and the pressure of desilicator and flash-pot is separated control, reaches its design pressure respectively, makes desilicator not take place related with flash-pot.
It is to make slip enter the desilicator reaction that described pressure with desilicator system and flash-pot system separates control, and reacted slip comes out from desilicator, and by valve regulated pressure, slurries enter flash-pot self-evaporatint n. cooling.
The setting device of desilicator and flash-pot system pressure, it comprises desilicator, flash-pot and is used to be connected the charge tube of desilicator and flash-pot, wherein set up the twice valve on charge tube.
Described valve is a gate valve.
Advantage of the present invention: the present invention is by the control to increase twice valve opening, realization is to the easy control of desilicator pressure and follow-up flash-pot pressure, alleviated the variation of the desilicator pressure that brings owing to the flash-pot pressure transient, stablize the desilicator operational condition, guaranteed desiliconization effect.This control method is easy and simple to handle; Owing to be to have increased by two gate valves only, with respect to adopting electronic or the pneumavalve adjusting, the effect of reducing investment outlay is obvious.
Description of drawings
Fig. 1 is the structural representation of desilicator of the present invention and flash-pot system pressure setting device.
Among the figure: 1, valve; 2, desilicator; 3, flash-pot; 4, charge tube.
Embodiment
The invention will be further described below in conjunction with accompanying drawing, but protection scope of the present invention is not limit by embodiment.
The control method of desilicator and flash-pot system pressure separates control with the pressure of desilicator and flash-pot, reaches its design pressure respectively, makes desilicator not take place related with flash-pot.It is to make slip enter desilicator 2 reactions that the pressure of desilicator system and flash-pot system is separated control, reacted slip comes out from desilicator 2, slip in the desilicator 2 is regulated pressure through the valve of being located on the charge tube 1, and slurries enter flash-pot 3 self-evaporatint n.s cooling.
The setting device of desilicator 2 and flash-pot 3 system pressures, it comprises desilicator 2, flash-pot 3 and is used to be connected the charge tube 4 of desilicator 2 and flash-pot 3 that wherein set up twice valve 1 on charge tube 4, valve 1 is a gate valve.
Claims (3)
1, the control method of desilicator and flash-pot system pressure, the pressure of desilicator and flash-pot is separated control, make desilicator not take place related with flash-pot, wherein the pressure of desilicator system and flash-pot system being separated control is to make slip enter desilicator (2) reaction, reacted slip comes out from desilicator (2), regulate pressure by twice valve (1), slurries enter flash-pot (3) self-evaporatint n. cooling.
2, the setting device of desilicator and flash-pot system pressure, it comprises desilicator (2), flash-pot (3) and is used to be connected desilicator (2) and the charge tube (4) of flash-pot (3), it is characterized in that setting up twice valve (1) on charge tube (4).
3, the setting device of desilicator according to claim 2 and flash-pot system pressure is characterized in that described valve (1) is a gate valve.
