Abstract

This invention discloses a low-temperature construction insulation system for epoxy mortar acid-resistant bricks in the field of chemical construction technology. It includes an insulation shed assembly for forming an insulation space, as well as a heating assembly, a layered insulation assembly, and a ventilation assembly. By setting up the layered insulation assembly, this invention effectively reduces the phenomenon of high-temperature air rising and low-temperature air sinking within the insulation space. Furthermore, the invention incorporates a through-slot with a diameter larger than that of the combustion device, and the air inlet is aligned with the upper end of the combustion device. This allows for the formation of a right-to-upper-lower airflow near the combustion device under airflow regulation, enabling a large amount of high-temperature airflow to enter the lower layers. Consequently, the temperature of the air layers decreases gradually from bottom to top, and this step-by-step insulation avoids excessive temperature differences between adjacent air layers. This significantly reduces the amount of thermal radiation, which helps to reduce fuel consumption.

Description

Technical Field

[0001] This invention relates to the field of chemical construction, specifically to a low-temperature construction insulation system for epoxy mortar acid-resistant bricks. Background Technology

[0002] Epoxy mortar and acid-resistant bricks are common combination materials used in chemical plants, storage tanks, trenches and other areas to deal with highly corrosive media. Epoxy mortar is used as a high-strength bonding and sealing layer, and acid-resistant bricks are laid on the base surface that needs to be protected to form a protective layer.

[0003] During the curing process, epoxy mortar and acid-resistant bricks need to be cured in an environment above 15℃ for 3-7 days. In ultra-low temperature construction environments, the curing time needs to be extended. When constructing epoxy mortar and acid-resistant bricks in low-temperature environments, the existing insulation solution is to build an insulation shed, and then lay electric heating blankets and insulation cotton quilts on the protective layer. Charcoal is continuously burned in the insulation shed to raise the temperature, and ventilation fans are used to prevent carbon monoxide from exceeding the standard. The shortcomings of this solution are: the heated air rises and the cold air falls in the insulation shed, resulting in a temperature difference between the top and bottom of the shed, a large temperature difference between the two sides of the shed roof and the two sides of the insulation cotton quilt, and the heat loss due to radiation is still relatively fast. In the extreme low temperature environment of -25℃, there is a problem of high energy consumption. Summary of the Invention

[0004] The purpose of this invention is to provide a low-temperature construction insulation system for epoxy mortar acid-resistant bricks, which solves the problem of rapid heat loss caused by the temperature difference between the top and bottom of the existing insulation shed.

Heating components include a heat tracing device covering the surface of epoxy mortar acid-resistant bricks, an insulation covering, and a combustion device for heating the insulated space. The layered insulation component includes several retractable insulation panels, which are spaced apart after being lowered to divide the insulation space into several air layers. The surface of the insulation panels is provided with a through groove with a diameter larger than that of the combustion device. A ventilation assembly, used for ventilation and for distributing flow to several air layers; The heat-insulating shed assembly has an air inlet, the height of which is aligned with the upper end of the combustion device. Temperature sensors are installed in several air layers to distribute the flow rate according to the temperature of each air layer, so that the temperature of each air layer decreases from bottom to top.

[0006] As a preferred embodiment of the present invention, the heat-insulating shed assembly includes a frame and an insulation cloth erected outside the frame. This embodiment uses a frame and insulation cloth to erect the heat-insulating shed, which are common materials in construction engineering, easy to implement and readily available.

By setting the specific position of the ventilation component, this embodiment makes the airflow from the outside to the inside of the heat preservation shed form, and makes the temperature of each air layer tend to be uniform while exchanging air.

[0008] As a preferred embodiment of the present invention, the ventilation assembly includes a negative pressure ventilation fan disposed at the center of the top of the insulation shed assembly. The bottom of the negative pressure ventilation fan is provided with an extension cylinder that penetrates the insulation board.

In this embodiment, an extension cylinder is provided, and the flow rate of air drawn from each air layer by the extension cylinder is further adjusted by the adjustment device to regulate the temperature.

[0009] As a preferred embodiment of the present invention, the adjusting device includes an inner cylinder rotatably disposed inside the extension cylinder. The surface of the inner cylinder is provided with an adjusting groove for aligning the air groove. The inner cylinder rotates to control the opening of the air groove by adjusting the adjusting groove. This embodiment further provides a specific structure for the adjusting device, which adjusts the opening of the air groove by rotating the inner cylinder to cause the adjusting groove to be misaligned with the air groove.

[0010] As a preferred embodiment of the present invention, the inner surface of the inner cylinder is provided with a spiral blade, and a tension spring is provided between the inner cylinder and the extension cylinder to control the rotation stroke of the inner cylinder by means of the airflow intensity of the ventilation component.

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1

[0018] like Figure 1-6 As shown, a low-temperature construction insulation system for epoxy mortar acid-resistant bricks includes an insulation shed component 1 for forming an insulation space, a heating component 2, a layered insulation component 3, and a ventilation component 4. The heating component 2 includes a heat tracing device 25 covering the surface of the epoxy mortar acid-resistant bricks, an insulation covering 26, and a combustion device 22 for heating the insulation space. The layered insulation component 3 includes several retractable insulation panels 31. The insulation panels 31 are spaced apart after being lowered to divide the insulation space into several air layers. The surface of the insulation panel 31 is provided with a through groove 32 with a diameter larger than that of the combustion device 22. The ventilation component 4 is used for ventilation and to distribute the flow rate to the several air layers. The heat preservation shed component 1 has an air inlet 13, and the height of the air inlet 13 is aligned with the upper end of the combustion device 22. Temperature sensors 6 are installed in several air layers to distribute the flow rate according to the temperature of each air layer, so that the temperature of each air layer decreases from bottom to top.

[0019] This embodiment effectively reduces the phenomenon of high-temperature air rising and low-temperature air falling within the insulation space by setting up a layered insulation component 3. Furthermore, it sets up a through groove 32 with a diameter larger than that of the combustion device 22, and the height of the air inlet 13 is aligned with the upper end of the combustion device 22. This allows an airflow from the upper right to the lower right to be formed near the combustion device 22 under the air layer flow regulation, so that a large amount of high-temperature airflow enters the lower layer. As a result, the temperature of the air layer can decrease layer by layer from bottom to top. The step-by-step insulation avoids excessive temperature difference between adjacent air layers, thereby greatly reducing the amount of radiation caused by thermal radiation, which is conducive to reducing fuel consumption.

[0020] In this embodiment, the combustion device 22 needs to be suspended in the air to prevent the ground from being scalded by the high temperature. This results in the high temperature zone generated by the combustion device 22 being located at an intermediate height. Therefore, an air inlet 13 is set at the height of the high temperature zone. The temperature is then controlled by drawing gas at different flow rates from each air layer. This allows the high temperature zone generated by the combustion device 22 to flow from top to bottom through the channel 32, so that the high temperature airflow can enter the lowest air layer.

[0021] Preferably, the insulation shed component 1 includes a frame 11 and an insulation cloth 12 erected outside the frame 11. This solution uses the frame 11 and the insulation cloth 12 to erect the insulation shed, which are common materials in construction engineering, easy to implement and readily available.

[0022] Preferably, the ventilation component 4 is located in the middle of the heat preservation space, the combustion device 22 is arranged around the ventilation component 4, and the air inlets 13 are all arranged on the heat preservation shed component 1 near the combustion device 22. By setting the specific position of the ventilation component 4, this solution makes the airflow from the outside to the inside of the heat preservation shed form, and makes the temperature of each air layer tend to be uniform while exchanging air.

[0023] Preferably, the ventilation assembly 4 includes a negative pressure ventilation fan 41 located at the center of the top of the insulation shed assembly 1. The bottom of the negative pressure ventilation fan 41 is provided with an extension cylinder 42 that penetrates the insulation board 31. The side wall or bottom wall of the extension cylinder 42 is provided with air grooves 43 corresponding to each air layer. An adjustment device for adjusting the opening of the air grooves 43 is provided inside the extension cylinder 42. In this solution, the extension cylinder 42 is provided, and the flow rate of air drawn from each air layer by the extension cylinder 42 is further adjusted by the adjustment device to regulate the temperature.

[0024] Preferably, the adjusting device includes an inner cylinder 44 rotatably disposed inside the extension cylinder 42. The surface of the inner cylinder 44 is provided with an adjusting groove 45 for aligning the air groove 43. The inner cylinder 44 rotates to make the adjusting groove 45 control the opening of the air groove 43. This solution further provides a specific structure for the adjusting device, which drives the adjusting groove 45 to be misaligned with the air groove 43 by rotating the inner cylinder 44, thereby adjusting the opening of the air groove 43.

[0025] Preferably, a spiral blade 46 is provided on the inner surface of the inner cylinder 44, and a tension spring 47 is provided between the inner cylinder 44 and the extension cylinder 42 to control the rotation stroke of the inner cylinder 44 by means of the airflow intensity of the ventilation assembly 4. In this solution, the spiral blade 46 is provided to drive the inner cylinder 44 to rotate, thereby adjusting the opening of the air groove 43. As an alternative implementation method, this embodiment can also be provided with an independent drive device to drive the inner cylinder 44 to rotate.

[0026] Preferably, the combustion device 22 is provided with a support 21 for suspension at the bottom, and a flue pipe 23 is provided at the upper end of the combustion device 22. The flue pipe 23 passes through the insulation board 31, and a heat sink 24 is provided on the outer surface of the flue pipe 23. In this solution, a combustion device is specifically provided. Alternatively, a gasoline drum can be modified. A feeding door for putting coal is opened on the middle side surface of the gasoline drum, and a combustion rack is placed inside the gasoline drum. Coal is placed on the combustion rack. An air inlet is opened at the bottom of the gasoline drum, and a flue pipe 23 is welded to the top of the gasoline drum, extending out to the outside of the insulation shed assembly 1.

[0027] Preferably, the layered insulation component 3 also includes a winding device 34 and a winding rope connecting the winding device 34 and the bottom insulation board 31. A connecting rope 33 is provided between each adjacent insulation board 31 and between the top insulation board 31 and the frame 11. This solution provides a specific structure for controlling the lowering and retraction of the insulation board 31. Four winding devices 34 are provided, which are respectively set at the four corners of the top of the frame 11 to suspend the four corners of the bottom insulation board 31.

[0028] Preferably, a carbon monoxide concentration sensor 5 is also installed at the bottom of the negative pressure ventilation fan 41 to prevent personnel from being poisoned.

[0029] Specific implementation: In this embodiment, the frame 11 has dimensions of 24m × 24m × 2.5m. A crossbeam is erected at the center of the top of the frame 11, and a ventilation assembly 4 is installed on the crossbeam. Door curtains for personnel to enter and exit are set at both ends of the insulated shed. Four combustion devices 22 are set, located inside the frame 11 near the four corners. Please refer to [link / reference]. Figure 1 The air layers are divided into the first air layer to the fifth air layer from bottom to top. Since this scheme uses a combustion device 22 modified from a gasoline drum, the high temperature area is in the third air layer and the fourth air layer. The fifth air layer is heated only by the residual heat of the exhaust pipe 23 and the natural radiation of the fourth air layer. In this embodiment, only the flow rates of the third and fourth air layers need to be adjusted to concentrate the airflow from the first and second air layers to achieve the effect of gradually decreasing temperature. Therefore, in this embodiment, the inner cylinder 44 only needs to adjust the opening of the corresponding air grooves 43 of the third and fourth air layers. By adjusting the opening of the air grooves 43, a large amount of airflow flows downward from the through grooves 43, moves laterally through the first and second air layers, and heats the first and second air layers. The first air layer enters from the bottom of the extension cylinder 42, and the second air layer enters from the side wall of the extension cylinder 42, so that the flow rate of the first air layer is greater than that of the second air layer, thereby making more high-temperature airflow pass through the first air layer, and the temperature of the first air layer is higher than that of the second air layer. The cross-sectional area of ​​the air slot 43 corresponding to the third air layer is larger than that of the fourth air layer, so that the high-temperature airflow passing through the third air layer is always greater than that of the fourth air layer during the opening adjustment process, thereby making the temperature of the third air layer higher than that of the fourth air layer. Based on the readings of the temperature sensors 6 in each air layer, the airflow ratios of the first and second air layers, as well as the third and fourth air layers, are dynamically adjusted. This causes the air layer temperature to decrease gradually from bottom to top. Under the requirement of ventilation, the airflow effectively reduces the temperature difference between the layers, greatly reducing the rate of air loss and helping to save coal.

[0030] When manual entry is required, the insulation board 31 can be rolled up by the winding device 34, and the entry can be determined based on the reading of the carbon monoxide concentration sensor 5.

[0031] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
