Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a double-layer condenser for chemical reactions. Background Art

[0002] In chemical processing, the condenser is a commonly used temperature control equipment and separation equipment. The existing condensers mainly adopt the tube row type. In order to improve the heat exchange effect, the tube row is usually made into a spiral or serpentine arrangement to improve the condensation effect. Although the heat exchange effect is improved to a certain extent by extending the heat exchange pipeline, this also causes the volume of the condenser to increase. In order to improve the heat exchange efficiency, the double-layer condenser disclosed in the patent publication number CN205007615U uses the cylindrical outer bottle body and the inner bottle body to form an insulation layer to ensure that the temperature loss in the bottle body is slow, thereby improving the energy utilization rate; further, a fixed screen is set to effectively fix the spiral condensation coil, increase the contact area between the spiral condensation coil and the inner bottle body, and ensure stability. However, although the above-mentioned condenser has a structure of arranging an insulation layer in the outer cylinder to avoid heat loss, it still uses a spiral tube row, which is complex and inconvenient to clean. In view of this, in-depth research was conducted on the above-mentioned problem, and thus this case was produced. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides an implementation scheme: the condensing tube of the double-layer condenser in the above-mentioned patent disclosure is designed with a spiral structure. Although the pipeline is extended to make the condensation effect better, its pipeline design is complicated, the production difficulty is high and it is not convenient for maintenance. Therefore, the present application uses a straight tube section on the condensation heat exchange tube. Specifically, a double-layer condenser for chemical reaction includes a condenser main pipe 1. The condenser main pipe 1 is the main support structure of the equipment and is also the external heat exchange space for the condensation heat exchange medium. The two ends of the condenser main pipe 1 are respectively connected to a first condensation liquid inlet 7 and a first condensation liquid outlet 8. The two ends of the condenser main pipe 1 are connected to the first condensation liquid inlet 7 and the first condensation liquid outlet 8. A pair of main material pipe sleeves 2 are coaxially connected at the end, and a feed pipe 3 and a discharge pipe 4 are respectively arranged on the pair of main material pipe sleeves 2. The pair of main material pipe sleeves 2 are used to circulate the fluid that needs to be condensed, wherein the main material pipe sleeve 2 connected to the feed pipe 3 is used to pass the fluid that needs to be condensed, and is isolated from the condensing medium flowing through the condenser main pipe 1 under the insulating effect of the first end plate 5, and is divided into a plurality of material through pipes 6 through a plurality of first through holes, flows into the main material pipe sleeve 2 connected to the discharge pipe 4, and then is discharged, and heat exchange and condensation are carried out with the heat exchange medium in the condenser main pipe 1 through the plurality of material through pipes 6. This is a heat exchange structure for external heat exchange of the condensed material;

[0021] At the same time, in order to improve the heat exchange efficiency, a pair of heat exchange tube sleeves 9 are arranged in a pair of main material tube sleeves 2. The pair of heat exchange tube sleeves 9 are the second working area of ​​the condensing medium. The pair of heat exchange tube sleeves 9 and the pair of main material tube sleeves 2 are isolated and sealed through a pair of second end plates 10, and are connected to each other through a plurality of internal heat exchange tubes 13. The second condensation liquid inlet 11 passes the heat exchange medium through the plurality of internal heat exchange tubes 13 to the side of the second condensation liquid outlet 12. The plurality of internal heat exchange tubes 13 are used to penetrate the plurality of material through pipes 6 to fully exchange heat inside the condensing material, so that the material can be fully condensed inside, so that the material is condensed evenly and the heat exchange efficiency is improved. In this way, the inner and outer double-layer condensation structure is used to improve the condensation efficiency, and the heat exchange parts are all straight pipe sections, which are easy to install and maintain.

[0022] As a preferred solution, further, a pair of main material pipe sleeves 2 are cylindrical pipe structures with both ends penetrated, which is convenient for installation and maintenance.

[0023] As a preferred solution, further, the pair of heat exchange tube sleeves 9 are cylindrical tubes with one end open and the other end blind, and a pair of second end plates 10 are respectively fixed on the open ends of the pair of heat exchange tube sleeves 9.

[0024] As a preferred solution, further, a pair of main material tube sleeves 2 and a pair of heat exchange tube sleeves 9 and the condenser main pipe 1 are respectively connected to each other through flange plates 14, which are tightly connected and convenient for disassembly and maintenance.

[0025] As a preferred solution, further, a pair of first control valves and a pair of second control valves are respectively provided on the first condensation liquid inlet 7 and the first condensation liquid outlet 8, and the second condensation liquid inlet 11 and the second condensation liquid outlet 12. The flow rate and switching of the heat exchange medium can be effectively improved through the first control valves and the second control valves.

[0026] As a preferred solution, further, a plurality of internal heat exchange tubes 13 coaxially pass through a plurality of material through tubes 6, and the diameter of the internal heat exchange tubes 13 is smaller than that of the material through tubes 6, which provides a circulation space for the fluid after heat exchange and facilitates the passage of materials.

[0027] In summary, it can be generally known that the double-layer condenser for chemical reactions adopts an inner and outer double-layer structure design to divert and guide the heat exchange fluid, and cooperates with the inner and outer double-layer condensation heat exchange medium to fully condense and exchange heat for the material, shortening the length requirement for the heat exchange pipeline, reducing the length requirement for the heat exchange pipeline, and facilitating subsequent disassembly and maintenance. At the same time, the inner and outer double-layer structure design will not lead to a decrease in heat exchange efficiency, so that the two are balanced.
