Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange of hydrogen peroxide and menthane, in particular to a heat exchange structure for the production of hydrogen peroxide and menthane. Background Art

[0002] At present, p-menthane hydroperoxide is a chemical substance, which is mainly used as an initiator for organic polymerization reactions, such as an initiator for styrene-butadiene rubber, a cross-linking agent for unsaturated polyesters, and also for the preparation of fragrances, etc. When p-menthane hydroperoxide is produced, a reactor is often used to mix and react it.

[0003] Hydrogen peroxide is an oxidizing agent. When it comes into contact with flammable substances, it will produce a violent reaction and release a large amount of heat energy. Menthane is a flammable liquid. When it comes into contact with hydrogen peroxide, its boiling point may change due to the heat generated by the reaction. It is necessary to use a heat exchanger to exchange heat between hydrogen peroxide and menthane.

[0004] However, when heat is exchanged between hydrogen peroxide and menthane through a heat exchanger in the market, it is difficult to monitor the pressure inside the heat exchanger, resulting in excessive pressure inside the heat exchanger, causing poor heat transfer effect, pipeline blockage and increased energy consumption. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] The utility model aims to provide a heat exchange structure for producing menthane with hydrogen peroxide, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat exchange structure for producing peroxymonane, comprising a heat exchanger, wherein multiple groups of equally spaced flow guide positioning plates are fixedly installed on both sides of the heat exchanger, multiple groups of equally spaced heat exchange tubes are fixedly installed in the multiple groups of flow guide positioning plates, a circulation cover is connected and installed on one side of the heat exchanger, and a pressure detection mechanism is detachably installed inside the circulation cover;

[0007] The pressure detection mechanism includes a detection plate fixedly installed inside the circulation cover, a detection cover fixedly installed in the middle of the detection plate, a sealing plate slidably installed inside the detection cover, an anti-pillar fixedly installed on one side of the sealing plate, and a pressure sensor fixedly installed in the middle of the inner wall of the circulation cover, and the pressure sensor and the anti-pillar correspond to each other.

[0008] As an optional solution of the technical solution of the present application, the outer wall of the support column is sleeved with a spring, and the inner wall of the detection cover and the outer wall of the support column on both sides of the spring are detachably installed, so that the support column can be reset.

[0009] As an optional solution of the technical solution of the present application, a diverter hood is installed on the other side of the heat exchanger, a diverter plate is fixedly installed in the middle of the diverter hood, and a second joint is installed on the top and bottom of the diverter hood to separate the introduced reactants.

[0010] As an optional solution of the technical solution of the present application, the top and bottom of the heat exchanger are connected and installed with a first joint. The first joint and the second joint at the top are both air inlets, and the first joint and the second joint at the bottom are both air outlets, which can perform heat exchange on the introduced liquid.

[0011] As an optional solution of the technical solution of the present application, a connecting pipe is installed on one side of the diverter hood, and a storage tank is installed on the other side of the connecting pipe. A solenoid valve is detachably installed on the connecting pipe, which can introduce high temperature pressure into the storage tank.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The technical solution of the present application continuously introduces high-temperature reactants into the diversion hood from the second joint, and then introduces them into the circulation hood from the heat exchange tube in turn. The high-temperature air pressure will introduce the reactants on the bottom side of the circulation hood from the bottom heat exchange tube to the bottom of the diversion hood, and discharge them from the second joint at the bottom to complete the heat exchange. At the same time, with the pressure detection mechanism installed inside the circulation hood, as the high-temperature reactants are continuously introduced, the sealing plate located in the detection hood will drive the anti-pillar to move and squeeze the pressure sensor on the inner wall of the circulation hood to detect the internal pressure of the circulation hood, so as to avoid excessive pressure and affect the heat transfer effect.

[0014] 2. The technical solution of the present application is connected to a connecting pipe installed on one side of the diversion hood, and a storage tank is installed on the other side of the connecting pipe. When the pressure sensor inside the circulation hood reaches the set pressure value, it will transmit a signal to the control processor, open the solenoid valve on the connecting pipe, and transmit the high-temperature air pressure to the storage tank, so as to avoid affecting the heat transfer effect and increasing energy consumption.

[0021] In this technical solution, after the high-temperature reactants are continuously introduced into the diverter hood 15 from the second joint 16, they will be introduced into the circulation hood 14 from the heat exchange tube 11 in turn. The high-temperature gas pressure will introduce the reactants on the bottom side of the circulation hood 14 from the bottom heat exchange tube 11 into the bottom of the diverter hood 15, and discharge them from the second joint 16 at the bottom to complete the heat exchange. At the same time, in conjunction with the pressure detection mechanism installed inside the circulation hood 14, as the high-temperature reactants are continuously introduced, the sealing plate 22 located in the detection hood 21 will drive the anti-pillar 23 to move and squeeze the pressure sensor 25 on the inner wall of the circulation hood 14 to detect the internal pressure of the circulation hood 14 to avoid excessive pressure and affect the heat transfer effect.
