Description

Technical Field

[0001] The utility model relates to the field of chemical processing equipment, in particular to a high-efficiency calcium chloride crude distillation kettle. Background Art

[0002] In an existing crude distillation kettle structure for recovering calcium chloride neutralized solution, the neutralized solution is transported to the crude distillation kettle via a filtrate pump, steam distilled, and the temperature in the kettle is controlled to 135° C., and the neutralized solution is then fed to the next process by gravity. However, since the heat provided by the steam is collected from the outside to the inside of the crude distillation kettle, the neutralized solution in the kettle is heated unevenly, which increases the heating time and reduces the distillation efficiency of the crude distillation kettle. Therefore, it is necessary to develop an efficient crude distillation kettle for calcium chloride that can uniformly heat the neutralized solution in the kettle, reduce the heating time, and thus improve the distillation efficiency of the crude distillation kettle. Utility Model Content

[0003] In response to the above technical problems, the utility model provides an efficient calcium chloride crude distillation kettle, which can evenly heat the neutralized liquid in the kettle, reduce the heating time, and thus improve the distillation efficiency of the crude distillation kettle, so as to solve the problems of uneven heating of the neutralized liquid in the existing kettle and increased heating time.

[0004] In order to solve the above technical problems, the utility model describes a high-efficiency calcium chloride crude steamer, comprising a cylinder, the top end of the cylinder is fixedly connected to a first head, the bottom end is fixedly connected to a second head, the first head is fixedly connected to a liquid inlet pipe, the second head is fixedly connected to a liquid outlet pipe, the outside of the cylinder is fixedly connected to an insulation barrel, a steam chamber is formed between the insulation barrel and the cylinder, one side of the insulation barrel is fixedly connected to a steam inlet pipe, the other side is fixedly connected to a steam outlet pipe, a number of guide plates are staggered and fixedly connected to the two side walls of the cylinder, and the liquid outlet pipe passes through the insulation barrel and extends to the outside thereof.

[0005] Furthermore, a support frame is fixedly connected between the insulation barrel and the cylinder.

[0006] Furthermore, the inner wall of the first head is provided with a thermal insulation layer.

[0007] Furthermore, the liquid inlet pipe and the liquid outlet pipe are connected to ball valves, and the steam inlet pipe and the steam outlet pipe are connected to control valves.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] The utility model divides the interior of the crude distillation kettle into a plurality of interconnected spaces by staggeredly and fixedly connecting a plurality of guide plates on both side walls of the cylinder body, thereby realizing stratification of the neutralization liquid entering the crude distillation kettle, thereby increasing the heating area of the liquid and the flow path of the neutralization liquid in the cylinder body. The distillation efficiency of the calcium chloride crude distillation kettle is improved through stratification and heat conduction of the guide plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 、 2 The shown embodiment is a high-efficiency calcium chloride crude steamer, comprising a cylinder 1, a first head 2 fixedly connected to the top end of the cylinder 1, a second head 3 fixedly connected to the bottom end, the first head 1 fixedly connected to a liquid inlet pipe 5, the second head 2 fixedly connected to a liquid outlet pipe 6, an insulating barrel 8 fixedly connected to the outside of the cylinder 1, a steam chamber 9 formed between the insulating barrel 8 and the cylinder 1, a steam inlet pipe 7 fixedly connected to one side of the insulating barrel 8, and a steam outlet pipe 10 fixedly connected to the other side. In order to increase the flow of liquid from the liquid inlet pipe 5 to the liquid outlet pipe 6, a number of guide plates 12 are staggered and fixedly connected to the inner side walls of the cylinder 1, and the liquid outlet pipe 6 passes through the insulating barrel 8 and extends to the outside thereof.

[0015] In order to facilitate the flow of the neutralized liquid into the crude steam kettle, the guide plate 12 is arranged obliquely.

[0016] In order to form a stable steam chamber 9 between the cylinder 1 and the insulation barrel 8, a support frame 11 is fixedly connected between the insulation barrel 8 and the cylinder 1.

[0017] In order to prevent the first head 2 which is not within the coverage of the insulation barrel 8 from losing heat, an insulation layer 4 is fixedly connected to the inner side of the first head 2 to block heat exchange.

[0018] In order to conveniently control the volume of the neutralizing liquid entering the crude steam kettle, and to control the temperature inside the crude steam kettle by controlling the flow rate of the steam entering the steam chamber 9, ball valves are connected to the ends of the liquid inlet pipe 5 and the liquid outlet pipe 6, and control valves are connected to the ends of the steam inlet pipe 7 and the steam outlet pipe 10.

[0019] In order not to affect the circulation of steam in the steam chamber 9, the support frame 11 adopts a U-shaped support frame.

[0020] The working process of this embodiment is as follows:

[0021] When using the calcium chloride crude steam kettle, first open the control valve at the end of the steam inlet pipe 7 to allow steam to enter the steam chamber 9 through the steam inlet pipe 7, and then open the control valve at the end of the steam outlet pipe 10 to allow steam to circulate in the steam chamber 9. At the same time, open the ball valve at the end of the liquid inlet pipe 5 to allow the neutralized liquid to flow into the liquid inlet pipe 5 through the filtrate pump and thus enter the cylinder 1. The neutralized liquid flows along the guide plate 12. After the liquid volume in the cylinder 1 meets the standard, close the ball valve at the end of the liquid inlet pipe 5. When the internal temperature of the cylinder rises to 135°C, open the ball valve at the end of the liquid outlet pipe 6 to allow the neutralized liquid to flow into the next process. After the work is completed, close the ball valve at the end of the liquid outlet pipe 6 and the control valve at the end of the steam inlet pipe 7. After the steam in the steam chamber 9 is discharged, close the control valve at the end of the steam outlet pipe 10.
