Abstract
The invention discloses ammonium sulfate crystallization equipment. The ammonium sulfate crystallization equipment comprises a crystallization pump (1), a centrifugal machine (2), an ammonium sulfate crystallization tank (3) and a saturator (4), wherein the ammonium sulfate crystallization tank (3) and the saturator (4) are connected through a main backflow pipeline (7); an auxiliary backflow pipeline (5) is further arranged between the ammonium sulfate crystallization tank (3) and the saturator (4), and the outlet of the auxiliary backflow pipeline (5) is communicated with the main backflow pipeline (7). By virtue of the technical scheme, the problem that gas is brought by mother liquid to flow back to the centrifugal machine from the backflow pipelines due to the long-time discharging of ammonium sulfate is solved; the loading speed and the backflow quantity are increased without changing the crystallization pump, the yield of ammonium sulfate is increased, and the resistance of the saturator is reduced; the operating accidents caused by the reasons are reduced, and the labor intensity of workers is lowered; the ammonium sulfate crystallization equipment is particularly applicable to the modification of equipment in the prior art and is high in net economic benefit.

The invention belongs to the technical field of the ammonium sulfate process in coke-oven gas production.More specifically, the present invention relates to a kind of sulphur crystalline ammonium equipment.
Background technology
At present, coke-oven gas deamination-Spray Saturator method produces the crystallizer tank that thiamine process configures, and has considered the coupling of material loading speed and quantity of reflux and the exhausting problem of backflow mother liquor.But, on equipment in the prior art, be not equipped with corresponding equipment.
For ensureing the continous-stable of saturex operation, corresponding transformation must be carried out to it.
Summary of the invention
The invention provides a kind of sulphur crystalline ammonium equipment, its objective is and ensure the continuous of saturex operation and stability.
To achieve these goals, the technical scheme that the present invention takes is:
Sulphur crystalline ammonium equipment of the present invention, comprise crystallization pump, whizzer, sulphur crystalline ammonium groove, saturex, described sulphur crystalline ammonium groove is connected by main reflux line with saturex, described sulphur crystalline ammonium groove and saturex are also provided with additional reflow pipeline, and the outlet of described additional reflow pipeline is communicated with main reflux line.
The top drilling of described main reflux line is connected with diffuse channel, and the height of described diffuse channel is higher than the height of saturex.
Described crystallization pump, to the ammonium sulfate liquor pipeline of sulphur crystalline ammonium groove, is the high speed mother liquor inlet pipe be tangentially connected with the junction of sulphur crystalline ammonium groove.
The present invention adopts technique scheme, solves the long-time discharging of sulphur ammonium and causes reflux line, and mother liquor band gas is from reflux line " adverse current " to the problem of whizzer; Under the condition not changing crystallization pump, increase material loading speed and quantity of reflux, improve sulphur ammonium output, reduce saturex resistance; Reduce the work accident because above-mentioned reason causes, reduce labor strength; Be particularly suitable for the transformation to existing processing unit, economic benefit clear height.
Accompanying drawing explanation
Brief description is marked as follows in content shown in accompanying drawing and figure:
Fig. 1 is the structural representation of the sulphur crystalline ammonium groove in the present invention;
Fig. 2 is that Spray Saturator of the present invention produces position structural representation in sulphur ammonium.
Be labeled as in figure:
1, crystallization pump, 2, whizzer, 3, sulphur crystalline ammonium groove, 4, saturex, 5, additional reflow pipeline, 6, diffuse channel, 7, main reflux line, 8, sulphur ammonium crystal grain, 9, high speed mother liquor inlet pipe.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technical scheme.
Structure of the present invention as shown in Figure 1 and Figure 2, be a kind of sulphur crystalline ammonium equipment, comprise crystallization pump 1, whizzer 2, sulphur crystalline ammonium groove 3, saturex 4, described sulphur crystalline ammonium groove 3 is connected by main reflux line 7 with saturex 4.
Ammonium sulfate liquor crystallizer tank is that the mother liquor containing sulphur crystalline ammonium bottom sulphur ammonium saturex 4 is pumped to eminence groove tank by a kind of crystallization pump 1 that utilizes.
During work, under the drive of whizzer 2, high speed mother liquor tangentially enters sulphur crystalline ammonium groove 3 by pipeline, and rotate to outlet in sulphur crystalline ammonium groove 3 inner high speed, return saturex 4, sulphur crystalline ammonium precipitates at sulphur crystalline ammonium groove 3.
In order to solve prior art Problems existing and overcome its defect, realize the goal of the invention ensureing the continuous of saturex operation and stability, the technical scheme that the present invention takes is:
As shown in Figure 1 and Figure 2, sulphur crystalline ammonium equipment of the present invention, wherein, sulphur crystalline ammonium groove 3 and saturex 4 are also provided with additional reflow pipeline 5, and the outlet of described additional reflow pipeline 5 is communicated with main reflux line 7.
On original crystallizer tank body, identical crystallization reflux line is designed with script in an additional road, is merged on main reflux line.The design that technique scheme of the present invention changes prior art is not enough, improves material loading speed, can also effectively prevent return line reflux.Utilize existing equipment, practicing every conceivable frugality cost in principle, reaching requirement of the present invention.
The top drilling of described main reflux line is connected with diffuse channel 6, and the height of described diffuse channel 6 is higher than the height of saturex 4.
At main reflux line top drilling, increase to saturex height, this height is as diffuse channel.
The ammonium sulfate liquor pipeline of described crystallization pump 1 to sulphur crystalline ammonium groove 3 is the high speed mother liquor inlet pipe 8 be tangentially connected with the junction of sulphur crystalline ammonium groove 3.
The present invention is under the situation do not stopped production at crystallization pump, utilizes stand-by facilities to complete transformation.
Effect of the present invention is:
1, solving the long-time discharging of sulphur ammonium causes reflux line, mother liquor band gas from reflux line " adverse current " to the problem of whizzer;
2, under the condition not changing crystallization pump, increase material loading speed and quantity of reflux, improve sulphur ammonium output, reduce saturex resistance;
3, reduce the work accident because above-mentioned reason causes, reduce labor strength;
4, be particularly suitable for existing technological transformation, economical and practical.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
