Description

Technical Field

[0001] The invention relates to the technical field of tubular heat exchangers, in particular to a dynamic tubular heat exchanger used for high-viscosity materials. Background Art

[0002] The dynamic tube heat exchanger for high viscosity materials is a specially designed heat exchange equipment suitable for processing fluids or materials with high viscosity. This type of heat exchanger usually consists of a group of pipes that can be used to heat, cool or evaporate high-viscosity materials. In order to increase the heat transfer efficiency, tubular heat exchangers usually use special heat exchange tube designs, such as spiral or threaded pipe inner walls, which increase the heat transfer surface area and can also help break the viscosity of the material. In order to prevent the material from accumulating and clogging in the pipe, tubular heat exchangers usually use a high-speed flow design to maintain the fluidity of the material through high-speed flow and reduce the effect of viscosity on the heat transfer effect. Due to the particularity of high-viscosity materials, tubular heat exchangers are usually designed to be easy to clean and maintain, such as detachable pipe components or easily accessible heat exchange surfaces for regular cleaning and maintenance to maintain the performance of the heat exchanger. Due to the particularity of high-viscosity materials, tubular heat exchangers usually use corrosion-resistant, high-temperature-resistant and wear-resistant materials to ensure the stability and durability of the equipment in long-term operation. In general, dynamic tubular heat exchangers for high-viscosity materials are heat exchange equipment specially designed for processing high-viscosity materials. They have the characteristics of efficient heat transfer, easy cleaning and maintenance, and are widely used in the processing of high-viscosity materials in chemical, petroleum, food and other industries;

[0003] Since high-viscosity materials have poor fluidity, the heat exchange efficiency will be reduced. At the same time, the fluidity of high-viscosity materials will be further reduced after the temperature drops. Therefore, it is necessary to increase the fluidity of high-viscosity materials in the heat exchanger, reduce the cleaning of high-viscosity materials in the later stage, and ensure that the heat exchanger can achieve maximum heat exchange.

[0005] In order to solve the problem that the high viscosity material has poor fluidity, the heat exchange efficiency will be reduced, and the fluidity of the high viscosity material will be further reduced after the temperature is reduced, it is necessary to increase the fluidity of the high viscosity material in the heat exchanger, reduce the cleaning of the high viscosity material in the later stage, and ensure that the heat exchanger can achieve the maximum heat exchange. The present invention provides the following technical solutions:

[0007] A heat exchange component is disposed inside the heat-insulating housing.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] As a preferred solution of the dynamic tubular heat exchanger for high-viscosity materials described in the present invention, wherein: the air intake cylinder is connected to an air intake pipe, and the air exhaust cylinder is connected to an exhaust pipe.

[0010] As a preferred embodiment of the dynamic tubular heat exchanger for high-viscosity materials described in the present invention, a reserved valve body is provided on the outer surface of the thermal insulation shell, a first air-release main valve pipe is provided on the outer surface of the thermal insulation shell, a first air-release auxiliary valve pipe is provided on one side of the first air-release main valve pipe, a second air-release main valve pipe is provided on the outer surface of the thermal insulation shell, and a second air-release auxiliary valve pipe is provided on one side of the second air-release main valve pipe.

[0011] As a preferred solution of the dynamic tubular heat exchanger for high-viscosity materials described in the present invention, an observation window and a monitoring chamber are provided on the outer surface of the heat-insulating shell.

[0012] As a preferred solution of the dynamic tubular heat exchanger for high-viscosity materials described in the present invention, a support frame is provided at the bottom of the heat-insulating shell, and support rods connected to support blocks are provided on the support frame.

[0013] As a preferred solution of the dynamic tubular heat exchanger for high-viscosity materials described in the present invention, the heat exchange component includes a gas transmission pipe body, a heat dissipation sheet and a pipe body assembly plate.

[0014] As a preferred solution of the dynamic tubular heat exchanger for high-viscosity materials described in the present invention, the gas delivery pipe body is corrugated, and the inner cavity of the gas delivery pipe body is uniformly engraved with inner tube heat dissipation grooves.

[0015] As a preferred embodiment of the dynamic tubular heat exchanger for high-viscosity materials described in the present invention, wherein: a heat dissipation guide strip is provided on the heat dissipation sheet, the heat dissipation guide strip is consistent with the flow direction of the liquid, and avoidance waist-shaped holes that cooperate with the gas delivery pipe body are evenly spaced on the heat dissipation sheet, and the two ends of the gas delivery pipe body are connected to the avoidance assembly holes evenly spaced on the pipe body assembly plate.

[0016] The beneficial effects of the present invention are as follows: a plurality of main deflation valve pipes and auxiliary deflation valve pipes are arranged in the heat-insulating shell, and the high-pressure gas in heat exchange in the heat-insulating shell is released in time, and an observation window is reserved to observe the situation inside the heat-insulating shell at any time, and the air pressure inside the heat-insulating shell is controlled and observed in time to prevent the heat-insulating shell from having too high air pressure. A plurality of main deflation valve pipes and auxiliary deflation valve pipes are arranged in the heat-insulating shell, which can relieve pressure while avoiding excessive heat loss inside the heat-insulating shell.

[0017] 2. The insulated shell may generate high-pressure gas during the heat exchange process. By setting the main air release valve pipe and the auxiliary air release valve pipe, the internal high-pressure gas can be released in time to avoid safety risks to the equipment or working environment due to excessive air pressure. The situation inside the insulated shell can be observed in real time through the observation window, including changes in air pressure. By controlling the opening and closing of the main air release valve pipe and the auxiliary air release valve pipe, the air pressure inside the insulated shell can be adjusted to keep it within a safe range. One of the main functions of the insulated shell is to maintain temperature stability during the heat exchange process. By setting the main air release valve pipe and the auxiliary air release valve pipe, excessive heat loss inside the insulated shell can be avoided while releasing pressure, thereby ensuring heat exchange efficiency and energy utilization.

[0018] The beneficial effects of the present invention are as follows: an in-tube heat dissipation slot is arranged in the inner chamber of the gas transmission pipe body, and when hot gas circulates, the heat exchange efficiency is higher, and the heat exchange efficiency can be further improved for high-viscosity materials. The corrugated shape increases the circulation time and surface area, and the in-tube heat dissipation slot increases the air resistance and the heat exchange area. The heat dissipation sheet and the heat dissipation guide strip on the heat dissipation sheet are arranged in the same flow direction as the liquid, which increases the fluidity of the liquid and can prevent the liquid from being retained for a certain period of time. At the same time, the heat exchange area of ​​the liquid can be increased, thereby improving the heat exchange efficiency.

[0019] Second, setting up an in-tube heat dissipation trough in the inner chamber of the gas transmission pipe body can improve the efficiency of heat exchange. This design uses the corrugated shape to increase the circulation time and surface area of ​​the hot gas, thereby increasing the heat transfer. Especially for high-viscosity materials, the corrugated shape can further improve the heat exchange efficiency. At the same time, the setting of the heat dissipation trough in the pipe also increases the air resistance and the heat exchange area. The advantage of this is that it can promote the hot gas to contact the pipe wall more fully and enhance the heat transfer effect. In addition, the heat dissipation sheet and the heat dissipation guide strips on the heat dissipation sheet are set in the same flow direction as the liquid. This design can increase the fluidity of the liquid, prevent liquid retention, and increase the heat exchange area of ​​the liquid. This setting can increase the flow rate and uniformity of the liquid during the heat exchange process, thereby further improving the heat exchange efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the outer surface of the heat-insulating shell 101 is also provided with an observation window 107 and a monitoring room 108;

[0035] like Figure 1 As shown, the heat-insulating shell 101 plays a role of heat insulation protection to prevent heat loss and the influence of the external environment on the components. The air inlet cylinder 102 and the exhaust cylinder 103 are used for the medium entering and exiting the heat exchange component 200, and are respectively connected to the air inlet pipe 102a and the exhaust pipe 103a. The liquid inlet pipe body 101-1 and the liquid discharge pipe body 101-2 are connected to the outer surface of the heat-insulating shell 101, and are used for introducing feed and discharging discharge. The valve body 104 is reserved for installing and controlling the valve so as to adjust the flow and pressure of the medium when necessary. The first air relief main valve pipe 105 and the first air relief auxiliary valve pipe 105a are used to discharge the gas in the medium and perform pressure relief operation when necessary. The second air relief main valve pipe 106 and the second air relief auxiliary valve pipe 106a are also used to discharge the gas in the medium and perform pressure relief operation when necessary.

[0036] Further, the air inlet cylinder 102 and the exhaust cylinder 103: the air inlet cylinder 102 and the exhaust cylinder 103 are used to guide the medium to enter and leave the heat exchange component 200, ensuring the smooth flow of the medium to achieve the effect of heat exchange, the liquid inlet pipe body 101-1 and the liquid discharge pipe body 101-2: the liquid inlet pipe body 101-1 and the liquid discharge pipe body 101-2 are connected to the outer surface of the heat-insulating shell 101, and are used to introduce feed and discharge discharge to ensure the normal supply and discharge of the medium, the reserved valve body 104: the reserved valve body 104 is used to install and control the valve, so as to adjust the flow and pressure of the medium when necessary, so as to realize the control and regulation of the heat exchange process, the first air relief main valve pipe 105 and the first air relief auxiliary valve pipe 105a: the first air relief main valve pipe 105 and the first air relief auxiliary valve pipe 105a Used to discharge the gas in the medium. When pressure relief operation is required, exhaust can be carried out through these channels to ensure the safe operation of the system. The second air relief main valve pipe 106 and the second air relief auxiliary valve pipe 106a: The second air relief main valve pipe 106 and the second air relief auxiliary valve pipe 106a are also used to discharge the gas in the medium, and perform pressure relief operation when necessary to ensure the stability and safety of the system.

They play an important role in the heat exchange system to ensure the normal operation and safety of the system;

[0037] A plurality of main deflation valve pipes and auxiliary deflation valve pipes are arranged on the heat-insulating shell 101 to timely release the high-pressure gas in heat exchange inside the heat-insulating shell 101, and an observation window 107 is reserved to observe the situation inside the heat-insulating shell 101 at any time, and timely control and observe the air pressure inside the heat-insulating shell 101 to prevent the heat-insulating shell 101 from having too high air pressure. A plurality of main deflation valve pipes and auxiliary deflation valve pipes are arranged on the heat-insulating shell 101 to relieve pressure while avoiding excessive heat loss inside the heat-insulating shell 101;

[0038] Furthermore, the heat-insulating shell 101 may generate high-pressure gas during the heat exchange process. By providing a main air-release valve pipe and a secondary air-release valve pipe, the internal high-pressure gas can be released in time to avoid safety risks to the equipment or the working environment due to excessive air pressure. The situation inside the heat-insulating shell 101, including changes in air pressure, can be observed in real time through the observation window. By controlling the opening and closing of the main air-release valve pipe and the secondary air-release valve pipe, the air pressure inside the heat-insulating shell can be adjusted to be kept within a safe range. One of the main functions of the heat-insulating shell 101 is to maintain temperature stability during the heat exchange process. By providing the main air-release valve pipe and the secondary air-release valve pipe, the excessive loss of heat inside the heat-insulating shell can be avoided while releasing the pressure, thereby ensuring heat exchange efficiency and energy utilization.

[0039] like Figure 3-Figure 6 As shown, the bottom of the heat-insulating housing 101 is equipped with a support frame 109, and the support frame 109 is provided with a support rod 109a for connecting the support block. The heat exchange assembly 200 includes a gas delivery pipe body 201, a heat dissipation sheet 202 and a pipe body assembly plate 203. The gas delivery pipe body 201 is corrugated, and the inner chamber 201a of the pipe is uniformly engraved with an inner heat dissipation groove 201a-1. The heat dissipation sheet 202 is provided with a heat dissipation guide strip 202b, which is consistent with the flow direction of the liquid. Waist-shaped holes 202a are evenly spaced on the heat dissipation sheet 202, which are matched with the gas delivery pipe body 201, and the two ends of the gas delivery pipe body 201 are connected with the avoidance assembly holes 203a evenly spaced on the pipe body assembly plate 203.

[0040] The heat-insulating housing 101 is used to provide external heat insulation protection for the heat exchange component and maintain the flow of heat energy inside the component. The support frame 109 and the support rod 109a are used to support the bottom of the heat-insulating housing 101 to ensure the stability and structural strength of the component. The gas transmission pipe body 201 is used to guide the flow of the medium and transport the medium from one end to the other end. The heat dissipation sheet 202 promotes the transfer and dissipation of heat by contacting with the medium to achieve the heat exchange process. The pipe body assembly plate 203 is used to connect and support the gas transmission pipe body 2 01 at both ends to ensure the overall structure and stability of the assembly. The heat dissipation slot 201a-1 in the tube is located in the tube chamber 201a of the gas delivery tube body 201, providing the function of increasing the heat exchange surface and improving the heat dissipation effect. The heat dissipation guide strip 202b is located on the heat dissipation sheet 202 to guide the flow of the medium and increase the efficiency of heat exchange. The waist-shaped hole 202a and the avoidance assembly hole 203a are used to connect and match the gas delivery tube body 201 and the tube body patchwork plate 203 to ensure the close combination and correct installation of the assembly.

[0041] An in-tube heat dissipation trough 201a-1 is arranged in the in-tube chamber 201a of the gas transmission pipe body 201, which has a higher heat exchange efficiency when hot gas circulates. For high-viscosity materials, the heat exchange efficiency can be further improved. The corrugated shape increases the circulation time and surface area. The in-tube heat dissipation trough 201a-1 increases the air resistance and the heat exchange area. The heat dissipation sheet 202 and the heat dissipation guide strip 202b on the heat dissipation sheet 202 are arranged in the same flow direction as the liquid, which increases the fluidity of the liquid and can prevent the liquid from being retained. At the same time, it can also increase the heat exchange area of ​​the liquid, thereby improving the heat exchange efficiency.

[0042] It is worth mentioning that an in-tube heat dissipation groove body 201a-1 is arranged in the tube chamber 201a of the gas transmission pipe body 201, which can improve the efficiency of heat exchange. The design uses the corrugated shape to increase the circulation time and surface area of ​​the hot gas, thereby increasing the heat transfer. Especially for high-viscosity materials, the corrugated shape can further improve the heat exchange efficiency. At the same time, the setting of the in-tube heat dissipation groove body 201a-1 also increases the air resistance and increases the heat exchange area. The advantage of this is that it can promote the hot gas to contact with the tube wall more fully and enhance the heat transfer effect. In addition, the heat dissipation plate 202 and the heat dissipation guide strip 202b on the heat dissipation plate 202 are arranged in the same flow direction as the liquid. Such a design can increase the fluidity of the liquid and prevent liquid retention. At the same time, it can also increase the heat exchange area of ​​the liquid. This setting can increase the flow rate and uniformity of the liquid during the heat exchange process, thereby further improving the heat exchange efficiency.
