Description

Technical Field

[0001] The utility model relates to the field of intelligent temperature control of chemical reaction tanks, and more specifically, to an intelligent temperature control device for chemical reaction tanks. Background Art

[0002] Many chemical reactions in the chemical industry need to be carried out at a specific temperature. The production process of many chemical products even requires dozens of temperature conversions and insulation processes to complete. The reaction tank with a temperature control device can realize the heating and insulation functions of the reactants in the tank. It is a basic device in the chemical industry to generate chemical products through chemical reactions. The existing chemical reaction temperature control devices mostly use electric heating rods or heaters to directly heat the tank. This heating method is prone to cause the reaction tank to be heated more locally and the rest to be heated less, resulting in uneven heating of the reactants in the reaction tank, affecting the chemical reaction and producing more impurity reactants. At the same time, the reactants near the heating rod or heater will dry out due to heat, which will bring pressure to the later cleaning of the inside of the reaction tank. The commonly used reaction tanks have a general insulation effect. For chemical reactions that need to be heated to a certain temperature for insulation, a temperature control device is usually required to continuously heat the reaction tank to offset the temperature loss caused by the cooling of the tank itself, which consumes a lot of energy. For some chemical reactions that require rapid cooling, most common temperature control devices achieve this through natural cooling, while some achieve this through the addition of refrigeration equipment. However, the above two cooling methods have major defects in cooling speed and energy saving. Summary of the invention

[0046] An upper cover 2 is fixedly arranged on the upper part of the temperature control tank body 1 .

[0047] Embodiment 2:

[0048] On the basis of Example 1, an intelligent temperature control device for a chemical reaction tank enters a standby state, and the operator completes the temperature control setting of the intelligent temperature control device of the reaction tank through the central controller 9 according to the reaction process and temperature requirements of the reactants. After the reactants are poured into the temperature control tank body 1, the central controller controls the I# circulation heating module 29, II# circulation heating module 30, and III# circulation heating module 31 in the temperature control box 4 to heat the heating oil in the heating chamber through the temperature control loop A5, the temperature control loop B6, and the temperature control loop C7. At this time, the circulating oil pump A18 in the I# circulation heating module 29 is operated to make the heating oil in the temperature control loop A5 circulate in the pipeline, and the heating module A15 heats the pipeline to continuously increase the temperature of the heating oil in the pipeline. Among them, the working principles of the II# circulation heating module 30 and the III# circulation heating module 31 are the same as those of the I# circulation heating module 29.

[0049] In the process of continuous heating of reactants in a temperature-controlled tank body 1 by an intelligent temperature control device for a chemical reaction tank, a heater temperature sensor 11 distributed in a heating chamber 3 and a temperature sensor 10 distributed on the inner wall of the temperature-controlled tank body 1 transmit their respectively collected temperature information back to a central controller 9, which analyzes and determines the temperature information, thereby accurately controlling the heating speed of each temperature control circuit and the flow speed of the heating oil in the circuit.

[0050] The specific control methods are: 1. Control the number of temperature control circuits started; 2. Separately control the heating speed and flow speed of the heating oil in the temperature control circuit; 3. Alternately start the three temperature control circuits.

[0051] During this process, in order to make the temperature of the heating oil in the heating chamber 3 more uniform and heat up faster, the central controller 9 will start the temperature rise and fall auxiliary control box 12 in a timely manner. After the temperature rise and fall auxiliary control box 12 is started, the auxiliary heat circulation pump 26 arranged inside it circulates the heating oil in the heating chamber 3 through the oil inlet pipe 13 and the oil return pipe 14, avoiding local overheating of the heating oil and making the heating oil heated more evenly, so that the reactants in the temperature control tank 1 are finally heated evenly.

[0052] Since the heating oil in the temperature control loop has the characteristic of thermal expansion and contraction, when the intelligent temperature control device for chemical reaction tank continuously heats the reactants in the temperature control tank body 1, the heating oil in each temperature control loop expands due to the heat, and the constant pressure valve set between the collector and the circulating heating module will automatically open when the pressure of the heating oil in the temperature control loop exceeds a certain value. At this time, the heating oil in the temperature control loop will pass through the constant pressure valve, collector 25, and oil pipeline 21, and finally be stored in the oil storage tank 8. On the contrary, when the temperature of the heating oil in the temperature control loop drops from high to low to a certain degree, the volume of the heating oil therein will shrink. At this time, after the pressure difference on both sides of the corresponding constant pressure valve reaches a certain value, the constant pressure valve automatically opens, and the heating oil will flow from the oil storage tank 8 through the oil pipeline 21, collector 25 and constant pressure valve into the corresponding temperature control loop until the pressure difference on both sides of the constant pressure valve returns to the set range.

[0053] For some chemical reactions that need to be heated to a certain temperature and kept warm for a certain period of time, each temperature control circuit cooperates with the temperature increase and decrease auxiliary control box 12 to achieve the heat preservation process of the reactants in the temperature control tank 1 with lower energy consumption.

[0054] For some chemical reactions that require rapid cooling, the central controller controls each temperature control circuit to stop working, and the temperature rise and fall auxiliary control box 12 continues to run. At this time, while the auxiliary heat circulation pump 26 arranged in the temperature rise and fall auxiliary control box 12 is running, the return oil pump 28 starts to run, and the heating oil with a higher temperature in the return oil pipe 14 is extracted. The proportional valve 27 is opened under the control of the central controller 9, and the heating oil with a lower temperature in the oil replenishment pipe 35 is mixed with the heating oil with a higher temperature in the return oil pipe 14 in proportion. Under the action of the auxiliary heat circulation pump 26, the oil enters the heating chamber 3 through the oil inlet pipe, and the oil temperature in the heating chamber 3 gradually decreases, thereby finally achieving rapid cooling of the reactants in the temperature control tank body 1 without cooling too fast, resulting in excessive reaction debris.

[0055] The external oil storage tank 38 supplies and discharges the heating oil to the temperature rise and fall auxiliary control box 12 through the external oil storage tank oil outlet pipe 39 connected to the oil replenishment pipe 35 and the external oil storage tank oil return pipe 40 connected to the oil drain pipe 37.

[0056] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
