Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating device technology, specifically a deweighting tower heating device. Background Technology
[0002] A heavy component removal tower is a chemical separation device mainly used to remove heavy component impurities (such as water, high-boiling-point organic matter or inorganic impurities) from liquid or gas mixtures. Its core principle is to achieve separation by utilizing the differences in volatility or density of the components in the mixture. In existing deweight removal tower systems, an external coil is typically installed on the outside of the tower body. Hot water or steam is circulated through the external coil to heat the tower body. This serves two purposes: firstly, it assists the original heating device in heating the internal structure of the deweight removal tower, reducing heat loss and ensuring uniform heating of the material inside the tower, avoiding localized overheating or underheating, and saving energy consumption; secondly, it reduces the wall thickness of the deweight removal tower and improves the stability of the tower body. However, during the implementation of the existing technology, the inventors discovered that the heat exchange medium in the external coil enters from the bottom end and flows out from the top end. During the flow of the heat exchange medium, heat is lost, resulting in a large temperature difference between the top and bottom of the tower body. Furthermore, the heat exchanged medium enters the cold water pool through the return water pipe, resulting in ineffective heat utilization and wasted heat. Utility Model Content

[0020] Example 1: See Figures 1 to 2 This is a schematic diagram of the various structures of this utility model, including a tower body 1. A first coil 2 is spirally wound around the outer side of the tower body 1. The bottom end of the first coil 2 is connected to a first inlet pipe 3, and the top end of the first coil 2 is connected to a first outlet pipe 4. A second outlet pipe 5 is connected to one side of the first outlet pipe 4. A second coil 6 is spirally wound around the upper part of the tower body 1. The bottom end of the second coil 6 is connected to a second inlet pipe 7, and the top end of the second coil 6 is connected to a third outlet pipe 8. Hot water in the first coil 2 enters through the first inlet pipe 3 and flows out through the first outlet pipe 4 or the second outlet pipe 5. Hot water in the second coil 6 enters through the second inlet pipe 3 and flows out through the second outlet pipe 4 or the second outlet pipe 5. Water enters through pipe 7 and flows out through pipe 8. The first inlet pipe 3 is connected to a hot water inlet pipe, which is connected to a hot water pump. The first outlet pipe 4 is connected to a hot water return pipe, and the third outlet pipe 8 is connected to a hot water return pipe, which is connected to a cold water tank. The hot water after heat exchange enters the cold water tank. A valve is installed between the first outlet pipe 4 and the hot water return pipe. When the water in the first coil 2 enters the heater 9, the valve is closed. A valve is also installed between the heater 9 and the second outlet pipe 5. When the second coil 6 is not needed for heating, the valve of the first outlet pipe 4 is opened and the valve of the second outlet pipe 5 is closed. A heater 9 is installed at the upper part of the tower body 1. The heater 9 includes a tank 91. A controller assembly 98 is installed at the upper end of the tank 91. Several sets of electric heating tubes 93 are installed inside the tank 91. The controller assembly 98 is electrically connected to the electric heating tubes 93. The electric heating tubes 93 are energized to heat the water in the tank 91. Several flow-disrupting plates 97 are installed inside the tank 91 to turbulent the water entering the tank 91 so that the water can be heated evenly and quickly. A third water inlet is installed at the top of the tank 91, and a third water inlet is installed at the bottom of the tank 91. The fourth water outlet pipe 95 is equipped with a temperature sensor 96, which is electrically connected to the controller assembly 98. The controller assembly 98 is a PLC-based control circuit board. Program instructions are given to the controller assembly 98 through remote communication. The controller assembly 98 controls the power of the electric heating tube 93 based on the data from the temperature sensor 96 to keep the water temperature of the fourth water outlet pipe 95 constant. The second water outlet pipe 5 is connected to the third water inlet pipe 94 through a pipe, and the fourth water outlet pipe 95 is connected to the second water inlet pipe 7 through a pipe.
[0021] Specifically, a support rod 92 is provided on the side of the tank body 91, and the support rod 92 is connected to the side wall of the tower body 1.
[0022] Specifically, the internal cavity of the tank 91 is cylindrical, the electric heating tube 93 is a U-shaped tube and is vertically arranged, the bottom end of the electric heating tube 93 corresponds to the bottom of the tank 91, the electric heating tube 93 fills the entire internal cavity of the tank 91, the baffle 97 is semi-circular, and several holes are provided on the baffle 97 and the holes are arranged to match the electric heating tube 93. If the baffle 97 is arranged alternately on the left and right, the water entering the tank 91 flows in an S-shape, so that the water travels a longer distance and can be heated fully and evenly.
[0023] The working principle of this utility model: Hot water from the heating station enters the first coil 2 through the first inlet pipe 3 via a water pump, heating the outer wall of the tower body 1. The inlet water temperature of the first inlet pipe 3 is 80 degrees Celsius. The valve between the first outlet pipe 4 and the hot water return pipe is closed. After heat exchange, the hot water flows into the heater 9 through the second outlet pipe 5. The temperature of the second outlet pipe 5 remains at 60 degrees Celsius after heat exchange. The hot water enters the heater 9, where the electric heating element 93 heats the hot water to 70 degrees Celsius. The controller assembly 98... The power of the electric heating tube 93 is adjusted according to the data returned by the temperature sensor 96. Since the lower half of the tower body 1 only has the first coil 2, the heat loss is relatively large. Therefore, the second coil 6 only needs to be heated to 70 degrees Celsius. The hot water enters the second coil 6 through the second inlet pipe 7 to heat the outer wall of the tower body 1. At the same time, it works with the first coil 2 to heat the outer wall to minimize the temperature difference between the upper and lower parts of the tower body 1. The water in the second coil 6 flows out to the cold water pool or enters the heat station for circulation through the third outlet pipe 8. Temperature measuring devices can be installed at both the upper and lower ends of the tower body 1. The temperature measuring devices are electrically connected to the controller assembly 98. The temperature of the water discharged from the third water inlet pipe 94 is automatically controlled by the temperature difference between the upper and lower ends of the tower body 1, thereby reducing the temperature difference between the upper and lower ends of the tower body 1.
[0024] This invention heats the upper part of the tower body 1 by installing two coils in the upper half of the tower body 1, reducing the temperature difference between the top and bottom of the tower body 1 and making the heating of the material inside the tower more uniform. This device also heats the heat exchanged medium in a secondary heating process before it enters the second coil 6 to heat the tower body 1. Compared with the heat station directly supplying heat to the second coil 6, this reduces the hot water path, effectively utilizes heat, and saves energy consumption. By installing two coils in the upper half of the tower body 1, this device can better support the upper half of the tower body 1, improve the stability of the tower body 1, and has good practicality.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
[0026] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
