Description

Technical Field

[0001] This utility model relates to the field of tank heat control technology, and more specifically, to a tank heat control system for chemical production. Background Technology

[0002] The tanks used in chemical production processes are generally large in volume, which leads to uneven heat exchange during heat exchange, resulting in uneven heat distribution and insensitive heat control. In existing technologies, heat exchange tubes are usually coiled around the outside of the tank, and the winding heat exchange tubes completely wrap around the outer wall of the tank to regulate the heat inside the tank. For example, the patent with publication number CN209260107U discloses a blast furnace soft water expansion tank. Specifically, it uses coiled heat exchange tubes on the outer wall of the expansion tank body to improve the heat exchange efficiency of the heat exchange tubes. However, the heat exchange medium inside can only enter from one end of the coiled heat exchange tubes and exit from the other end. When it is applied to large tanks used in chemical production, the temperature of the heat exchange medium gradually increases or decreases, and by the time it reaches the vicinity of the outlet end, it can no longer play a significant heat regulation effect, resulting in uneven heat regulation inside the tank. Based on the above description, there is an urgent need for a heat control system that can uniformly regulate the heat of large chemical production tanks. Utility Model Content

Detailed Implementation

[0015] Example 1 Please see Figures 1 to 3 The present invention provides the following technical solution: a heat regulation system for tanks used in chemical production, which is suitable for situations where the heat of large tanks needs to be uniformly regulated in chemical production.

[0016] Specifically, such as Figure 1 and Figure 2 As shown, a heat control system for a tank in chemical production includes a shell 1 and a tank 2, and also includes a pair of heat exchange devices 3 and a pair of heat collection devices 4; the tank 2 is disposed inside the shell 1; a heat exchange annular gap 5 is provided between the tank 2 and the shell 1; the pair of heat exchange devices 3 are disposed opposite to each other at both ends of the shell 1; the heat exchange devices 3 are connected to the heat exchange annular gap 5; the pair of heat collection devices 4 are disposed opposite to each other at the end of the heat exchange annular gap 5 away from the heat exchange devices 3; the heat collection devices 4 are disposed between the shell 1 and the tank 2.

[0017] The specific implementation process is as follows: heat exchange medium is introduced into both ends of the heat exchange annular gap 5 through a pair of heat exchange devices 3. After the heat exchange medium is introduced, it gradually diffuses along the arc wall of the tank 2 to both ends, thereby exchanging heat with the tank 2. The pair of heat collection devices 4 can play a role in stabilizing the flow, that is, reducing the flow velocity of the heat exchange medium that diffuses to the end away from the heat exchange device 3, so as to fully exchange heat with the tank 2. In addition, the pair of heat exchange devices 3 are arranged opposite each other, so that the two heat exchange mediums reaching the heat collection device 4 cancel each other out and further reduce the flow velocity, thereby avoiding uneven local heat adjustment of the tank 2 due to heat reduction when the heat exchange medium is near the end of the heat exchange.

[0018] In this embodiment, the heat exchange medium can be either liquid or gas; this embodiment takes gas as an example.

[0019] In this embodiment, the outer ring of the tank body 2 is provided with multiple inserts, and the shell 21 is provided with an opening groove for the inserts to be inserted, thereby realizing that the tank body 2 is stably installed inside the shell 1, and the heat exchanged medium is extracted from the bottom of the shell 1 through the exhaust pipe 8.

[0020] Specifically, such as Figure 1 and Figure 2 As shown, the heat exchange device 3 includes a hot air blower 31, multiple air inlet pipe groups 32 and air outlet pipe groups 33; one end of the air inlet pipe group 32 is connected to the hot air blower 31; the other end of the air inlet pipe group 32 is connected through the air outlet pipe group 33; the air outlet pipe group 33 is connected to the heat exchange annular gap 5.

[0021] In this embodiment, the hot air blower 31 sends hot air into the air inlet pipe group 32, and further passes the hot air into the heat exchange annular gap 5 through the air outlet pipe group 33 for heat exchange.

[0022] Specifically, such as Figure 1 and Figure 2 As shown, the air inlet duct assembly 32 includes an air inlet main pipe 321 and multiple parallel air inlet branch pipes 322; one end of the air inlet main pipe 321 is connected to the hot air blower 31; the other end of the air inlet main pipe 321 is connected to the air outlet duct assembly 33; and the air inlet branch pipes 322 are connected between the hot air blower 31 and the air inlet main pipe 321.

[0023] In this embodiment, multiple parallel air inlet branch pipes 322 can provide sufficient hot air to the air outlet pipe group 33 together with the main air inlet pipe 321, ensuring that sufficient heat is provided for heat exchange of the tank 1; similarly, when it is necessary to cool the tank 2, a cold air fan can be used for cooling.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the air outlet duct assembly 33 includes a main air outlet 331 and multiple parallel air outlet branch ducts 332; the main air outlet 331 is connected to the heat exchange annular gap 5 through the air outlet branch ducts 332.

[0025] In this embodiment, multiple air outlet branch pipes 332 are connected at intervals along the vertical direction to the heat exchange annular gap 5, thereby enabling the heat exchange medium to be uniformly transferred to various parts of the tank 2.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, the heat collection device 4 includes multiple first partitions 6 and multiple second partitions 7; the multiple first partitions 6 and multiple second partitions 7 are alternately arranged at the end of the heat exchange annular gap 5 away from the heat exchange device 3.

[0027] In this embodiment, multiple first baffles 6 and multiple second baffles 7 are alternately arranged at the end of the heat exchange annular gap 5 away from the heat exchange device 3, thereby forming a stagnant S-shaped flow channel, which plays a role in stagnant flow and speed reduction, so as to facilitate slow heat exchange between the heat exchange medium and the tank 2.

[0028] In this embodiment, multiple first partitions 6 are spaced apart along the circumferential direction on the inner sidewall of the shell 1; the end of the first partition away from the shell 1 extends toward the outer sidewall of the tank 2; multiple second partitions 7 are spaced apart along the circumferential direction on the outer sidewall of the tank 2; the end of the second partition 7 away from the tank 2 extends toward the inner wall of the shell 1.

[0029] In this embodiment, the gaps between multiple first baffles 6 gradually decrease towards the end furthest from the heat exchange device 3; similarly, the gaps between multiple second baffles 7 gradually decrease towards the end furthest from the heat exchange device 3. This further ensures that the flow rate of the heat exchange medium changes accordingly as the heat changes, thereby causing variations in the heat exchange time in different areas of the tank 2 and achieving uniform heat control in all parts of the tank 2.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
