Sodium bicarbonate wet feed carries out pneumatic conveying drying, and after moisture is up to standard, cooling obtains sodium bicarbonate finished product.Can be according to reality
Need the control parameter in this utility model production process of sodium bicarbonate is configured.
Specific implementation process of the present utility model:
First stage production process (draws the magma in carbonators magma pipeline as crystal seed):
From company's existing sodium bicarbonate device, carbonators goes out an alkali liquor mouth piece pipeline of extraction, by the alkali liquor with magma
It is incorporated into reaction crystalizer 1 from standby mouth 2, meanwhile opens mother liquor pipeline 14 and alkali liquor pipeloop
10 controls solid-to-liquid ratio within whole reaction crystalizer 1 is 0.05-0.15:1, after treating that liquid level reaches setting value,
Opening alkali liquor intake pipeline 15 and gaseous mixture intake pipeline 7, the liquid inlet volume of alkali liquor is 0.51m3/h-1m3/ h,
Mixed gas air inflow controls at 70m3/h-80m3/ h, makes fully to react between raw material, adjusts mother in course of reaction
Liquid conveying capacity, thin brilliant flow quantity of discharging is controlled by the first level chain control instrument 18, reacted magma
Constantly carried out outer loop by alkali liquor pipeloop 10, extend the reaction in reaction crystalizer 1 and knot
The brilliant time.Larger-size magma is expelled to stiff surge tank 22 carry out stiff from magma discharge pipe 20,
Sending into centrifuge 24 through magma pump 23, the sodium bicarbonate wet feed after being centrifuged the most at last carries out pneumatic conveying drying, water
After dividing content up to standard, cooling obtains sodium bicarbonate finished product, and product index reaches industry standard.
Mass content after testing: the product cut size that obtains<120 mesh (particle diameter>125 μm)>65%, 80 mesh-120
The mass content of mesh (125 μm particle diameter 180 μm) > 50%, 40 mesh-80 mesh (180 μm particle diameter 420 μm)
Mass content>5%,<40 mesh (particle diameter>420 μm)>10%.
Second stage production process (autogamy magma is as crystal seed):
The particle diameter produced first stage is that 40-80 mesh sodium bicarbonate solid particle is from the standby mouth of reaction crystalizer 1
2 add, and open mother liquor pipeline 14 and alkali liquor pipeloop 10 controls the solid-liquid within whole reaction crystalizer 1
Ratio is 5%-15%.After treating that liquid level reaches setting value, open alkali liquor intake pipeline 15 and gaseous mixture intake pipeline
7, the liquid inlet volume of alkali liquor is 0.51m3/h-1m3/ h, mixed gas air inflow controls at 70m3/h-80m3/ h,
Making fully to react between raw material, adjust mother solution conveying capacity in course of reaction, thin brilliant flow quantity of discharging is joined by the first liquid level
Lock control instrument 18 controls, and reacted magma constantly carries out outer loop by alkali liquor pipeloop 10,
Extend the reaction in reaction crystalizer 1 and crystallization time.Larger-size magma is from magma discharge pipe 20
It is expelled in stiff surge tank 22 carry out stiff, sends into centrifuge 24 through magma pump 23, be centrifuged it the most at last
After sodium bicarbonate wet feed carry out pneumatic conveying drying, after moisture is up to standard, cooling obtain sodium bicarbonate finished product, product refers to
Mark reaches industry standard.
After testing: the product that obtains<80 mesh (particle diameter>180 μm) mass content>75%, 40 mesh-80 mesh (180
μm<particle diameter<420 μm) mass content>40%,<40 mesh (particle diameter>420 μm)>35%.
From figure 3, it can be seen that the mean diameter of product that this utility model is produced has reached 363.1 μm.
It addition, as can be seen from Figure 4 and Figure 5, the product that this utility model is produced mainly exists with bar form,
Mainly grow up by the way of crystallization, rather than subsequent granulation processing realizes the increase of particle diameter.
Although being described function of the present utility model and work process above in conjunction with accompanying drawing, but this practicality is new
Type is not limited to above-mentioned concrete function and work process, and above-mentioned detailed description of the invention is only schematically
Rather than restrictive, those of ordinary skill in the art under enlightenment of the present utility model, without departing from
In the case of this utility model objective and scope of the claimed protection, it is also possible to make a lot of form, these are equal
Within belonging to protection of the present utility model.
