Abstract
A kind of grey crystallization apparatus of soda ash weight is the utility model is related to, including hydration machine, centrifuge and fluid bed, hydration machine are connected by magma pump with centrifuge, the discharge gate of centrifuge is connected with fluid bed, and thickener is connected between the hydration machine and centrifuge；The filtrate port of the centrifuge and the inlet of hydration machine are connected, and filtrate heat exchanger is connected between centrifuge and hydration machine.This programme cools down to filtrate by increasing filtrate heat exchanger, stable hydration machine reaction temperature, improves hydration machine solid-to-liquid ratio.Increase thickener, extend magma crystallization time.Under production capacity same case, hydration machine start number of units is reduced, saves electric energy.Realize the lifting of heavy soda ash quality and the decline of energy consumption.
Description
Technical field
The utility model provides a kind of grey crystallization apparatus of soda ash weight, belongs to technical field of chemical.
Background technology
In heavy soda ash production process, the quality of crystallization is directly connected to product quality and energy consumption height.Use at present
Light soda ash is crystallized to form heavy soda ash again by the method for liquid-phase hydration, and material reaction can discharge largely in hydro-combination process
Heat, it is too high or too low for temperature all to influence crystalline quality.Especially in summer, hydration machine temperature drift more than 99 DEG C after crystallize become
Difference, solid-to-liquid ratio reduce, and grain size number reduces, fine powder amount increase.Soda ash fine powder after alkali sieves is returned to system and crystallized again, from
And cause yield reduction, power consumption increase.
The content of the invention
To solve the above problems, this programme discloses a kind of grey crystallization apparatus of soda ash weight, concrete scheme is：
A kind of grey crystallization apparatus of soda ash weight, including hydration machine, centrifuge and fluid bed, hydration machine pass through magma pump and centrifugation
Machine is connected, and the discharge gate of centrifuge is connected with fluid bed, and thickener is connected between the hydration machine and centrifuge；The centrifugation
The filtrate port of machine and the inlet of hydration machine are connected, and filtrate heat exchanger is connected between centrifuge and hydration machine.
Further, the hydration machine is rotary drum hydration machine, and the rotary drum of rotary drum hydration machine is provided with heat exchange jacket, described
After filtrate heat exchanger is connected with heat exchange jacket, then it is connected with the inlet of hydration machine.
Further, the filtrate heat exchanger is plate type heat exchanger.
Beneficial point of the present utility model is：This programme is cooled down, stable water by increasing filtrate heat exchanger to filtrate
Conjunction machine reaction temperature, improve hydration machine solid-to-liquid ratio.Increase thickener, extend magma crystallization time.Under production capacity same case, subtract
Few hydration machine start number of units, saves electric energy.Realize the lifting of heavy soda ash quality and the decline of energy consumption.In improvement project, utilize
Filtrate after cooling is exchanged heat in advance with hydration machine, is approached the magma temperature in filtrate temperature and rotary drum, low temperature can be avoided to filter
Liquid is directly entered in rotary drum the problem of causing temperature inequality, can further improve crystalline quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The grey crystallization apparatus of a kind of soda ash weight as shown in Figure 1, including hydration machine 1, centrifuge 5 and fluid bed 7, hydration machine 1
Be connected by magma pump 3 with centrifuge 5, the discharge gate of centrifuge 5 is connected with fluid bed 7, the hydration machine 1 and centrifuge 5 it
Between be connected with thickener 4；The filtrate port of the centrifuge 5 is connected with the inlet of hydration machine 1, between centrifuge 5 and hydration machine 1
It is connected with filtrate heat exchanger 6.
The hydration machine 1 is rotary drum hydration machine, and the rotary drum of rotary drum hydration machine is provided with heat exchange jacket 2, and the filtrate is changed
After hot device 6 is connected with heat exchange jacket 2, then it is connected with the inlet of hydration machine 1.
The filtrate heat exchanger 6 is plate type heat exchanger.
This programme cools down to filtrate by increasing filtrate heat exchanger, stable hydration machine reaction temperature, improves hydration machine
Solid-to-liquid ratio.Increase thickener, extend magma crystallization time.Under production capacity same case, hydration machine start number of units is reduced, saves electricity
Energy.Realize the lifting of heavy soda ash quality and the decline of energy consumption.In improvement project, carried out using the filtrate after cooling and hydration machine
Pre- heat exchange, approaches the magma temperature in filtrate temperature and rotary drum, low temperature filtrate can be avoided to be directly entered in rotary drum and cause temperature
The problem of uneven, it can further improve crystalline quality.
