Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel jacket technology, specifically to a high-temperature resistant ceramic fiber jacket for an acidification vessel. Background Technology
[0002] A jacket is an outer sleeve added to the outside of a container (or pipe). Heating media such as steam, hot water, or hot oil can be introduced into the jacket to heat the material inside the container (or pipe), or cooling media such as cooling water or other cooling fluids can be introduced to cool the material inside the container (or pipe).
[0003] Existing high-temperature resistant ceramic fiber jackets for acidification reactors are generally directly fitted onto the outside of the reactor body for external heat circulation. However, a baffle plate is not installed in the sealed cavity between the jacket and the reactor to divide the sealed cavity into two heating chambers, ensuring a constant internal temperature after the set temperature is reached. Furthermore, the inner heating chamber lacks a heat-conducting plate that can contact the reactor to transfer heat from the inner chamber into the reactor, thus affecting the jacket's heat circulation conversion rate. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a high-temperature resistant ceramic fiber jacket for acidification reactors to solve the technical problems of existing high-temperature resistant ceramic fiber jackets for acidification reactors, which do not have a baffle plate installed in the sealed cavity between the jacket and the acidification reactor to divide the sealed cavity into two heating cavities, so that the internal temperature of the acidification reactor can be kept constant after reaching the set temperature. At the same time, the inner heating cavity does not have a heat-conducting plate that can come into contact with the reactor to transfer the heat in the heating cavity into the acidification reactor in a timely manner, thus affecting the jacket thermal cycle conversion rate of the acidification reactor.
[0005] According to the technical solution provided in the embodiments of this application, a high-temperature resistant ceramic fiber jacket for an acidification reactor includes a jacket body, which is sleeved on the outside of the acidification reactor body for internal heating of the acidification reactor body.
[0006] A partition is installed on the inner side of the outer shell of the jacket body so that the partition divides the cavity between the outer shell and the acidification vessel body into a first heating chamber and a second heating chamber. The first heating chamber is located outside the second heating chamber so that the first heating chamber and the second heating chamber can perform multi-stage circulating heating on the acidification vessel.
[0007] Several heat-conducting plates are arranged side by side and spaced apart in the second heating chamber, and each heat-conducting plate abuts against the outside of the acidification vessel body, so as to quickly transfer the heat in the jacket body into the acidification vessel.
[0008] Furthermore, both the partition and the heat-conducting plate are made of metal.
[0009] Furthermore, the heat-conducting plates are L-shaped, and each heat-conducting plate is provided with a plurality of staggered flow holes for the flow of the heating medium.
[0010] Furthermore, a first liquid inlet pipe is connected to the side of the outer shell, and a first liquid outlet pipe is connected to the bottom of the outer shell, so that the heating medium enters the first heating chamber from the first liquid inlet pipe and exits from the first liquid outlet pipe, for the heating medium to circulate and heat the first heating chamber.
[0011] Furthermore, a second liquid inlet pipe is connected to the side of the partition, which is used for the heating medium of the second heating chamber to enter, and a second liquid outlet pipe is connected to the bottom of the partition, which is used for the heating medium of the second heating chamber to exit.
[0012] Furthermore, the partition has a U-shaped cylindrical structure.
[0013] Furthermore, the outer shell is made of high-temperature resistant ceramic fiber material.
[0014] In summary, the beneficial effects of this application are as follows:
[0015] 1. By setting a U-shaped partition in the cavity between the jacket and the acidification reactor, the partition divides the cavity into a first heating cavity and a second heating cavity, so that the first heating cavity and the second heating cavity form an independent circulating heating system. This allows the jacket to inject or discharge heating medium into the second heating cavity according to the acidification temperature requirements inside the acidification reactor, thereby regulating the internal temperature of the acidification reactor. At the same time, heating medium can be injected into the first heating cavity as needed to keep the acidification reactor warm, thereby improving the heat conversion efficiency of the jacket to the acidification reactor and improving the practicality of the jacket.
[0016] Second, by setting several metal heat-conducting plates with staggered flow holes inside the second heating chamber, so that each heat-conducting plate abuts against the outside of the acidification vessel body, the heat in the heating medium flowing through the second heating chamber is promptly introduced into the acidification vessel, thereby improving the heat conversion efficiency of the heating medium and the practicality of the jacket.

[0028] As a preferred embodiment, please refer to Figure 3 and Figure 4 Several heat-conducting plates 150 are arranged in an L-shape, and each heat-conducting plate 150 is provided with several interlaced flow holes 151, so as to increase the contact between the heat-conducting plates 150 and the heating medium, so that the heating medium injected into the first heating chamber 130 flows through each heat-conducting plate 150, thereby introducing the heat of the heating medium into the acidification kettle.

[0033] The working principle of this high-temperature resistant ceramic fiber jacket for acidification reactor is as follows:
[0034] During the thermal circulation heating process of the acidification reactor using a high-temperature resistant ceramic fiber jacket, the jacket body 100 is fitted around the outside of the acidification reactor body 200. A partition 110 is installed in the cavity between the high-temperature resistant ceramic fiber outer shell 120 on the jacket body 100 and the acidification reactor body 200. The partition 110 divides the cavity into a first heating chamber 130 and a second heating chamber 140. Both the first heating chamber 130 and the second heating chamber 140 have independent thermal circulation systems. The second heating chamber 140 is located inside the first heating chamber 130 and is connected to the outside of the acidification reactor body 200. To improve the heat conversion efficiency between the heating medium inside the second heating chamber 140 and the acidification reactor body 200, several heat-conducting plates 150 with flow holes 151 are installed inside the second heating chamber 140 to allow several... A metal heat-conducting plate 150 rapidly introduces the heating medium flowing through the second heating chamber 140 into the acidification reactor body 200. Simultaneously, the first heating chamber 130 and the second heating chamber 140 on the jacket can, according to the temperature requirements of the acidification reactor, allow the heating medium from the second inlet pipe 180 to enter the second heating chamber 140. At the same time, the heating medium is discharged from the second drain pipe 190 connected to the bottom of the second heating chamber 140, so that the second heating chamber 140 circulates and heats the acidification reactor, thereby regulating the internal temperature of the acidification reactor. At the same time, as needed, the heating medium can be injected into the first heating chamber 130 from the first inlet pipe and discharged from the first drain pipe 170 in the first heating chamber 130, so that the first heating chamber 130 keeps the acidification reactor internally warm, thereby improving the heat conversion efficiency of the jacket for the acidification reactor and the practicality of the jacket.
[0035] The beneficial effects of this invention for a high-temperature resistant ceramic fiber jacket used in an acidification reactor are as follows:
[0036] 1. By setting a U-shaped partition 110 in the cavity between the jacket and the acidification reactor, the partition 110 divides the cavity into a first heating cavity 130 and a second heating cavity 140, so that the first heating cavity 130 and the second heating cavity 140 form an independent circulating heating system. This allows the jacket to inject or discharge heating medium into the second heating cavity 140 according to the acidification temperature requirements inside the acidification reactor, thereby regulating the internal temperature of the acidification reactor. At the same time, heating medium can be injected into the first heating cavity 130 as needed to keep the acidification reactor warm, thereby improving the heat conversion efficiency of the jacket to the acidification reactor and improving the practicality of the jacket.
[0037] Second, by setting a number of metal heat-conducting plates 150 with staggered flow holes 151 inside the second heating chamber 140, so that each heat-conducting plate 150 abuts against the outside of the acidification vessel body 200, the heat in the heating medium flowing through the second heating chamber 140 is promptly introduced into the acidification vessel, thereby improving the heat conversion efficiency of the heating medium and the practicality of the jacket.
