Description

Technical Field

[0001] This utility model belongs to the technical field of heat energy exchange equipment, and in particular relates to a skid-mounted integrated heating device. Background Technology

[0002] In the field of heat exchange, traditional heating systems typically employ a decentralized equipment layout, with heat exchangers, circulating pumps, valves, and control systems installed independently in a machine room, connected by numerous pipes to achieve heat exchange. However, this type of traditional system faces several technical bottlenecks in practical applications:

[0003] 1. Traditional heat exchange stations require dedicated machine rooms, resulting in large floor space requirements due to dispersed equipment layout (e.g., a small to medium-sized community heat exchange station typically occupies 50-100 square meters). Furthermore, the piping layout is complex, with numerous elbows, valves, and other connectors. For space-constrained scenarios such as industrial parks and renovations of older residential areas, traditional systems are difficult to adapt, sometimes requiring large-scale structural modifications to buildings, increasing construction costs and timelines. In addition, on-site installation is cumbersome, requiring extensive welding and pipe insulation work, leading to low construction efficiency and a high risk of leaks.

[0004] 2. The dispersed layout of equipment makes fault diagnosis difficult, requiring regular manual inspections. Furthermore, maintenance necessitates shutting down part or all of the system, affecting the continuity of heating. For example, when heat exchangers become scaled or circulating pumps malfunction, extensive pipework must be disassembled for repairs, with single maintenance costs reaching several thousand yuan and downtime lasting several hours.

[0005] 3. Traditional systems often employ non-standard designs, making them difficult to adapt to different heat sources (such as industrial waste heat, geothermal energy, and gas-fired boilers). When the type of heat source changes, a complete overhaul is required. Furthermore, fixed modular designs cannot flexibly expand with increasing heating demand. If the heating area needs to be increased, a new heat exchange station is often required, resulting in high initial investment costs.

[0006] Therefore, a skid-mounted integrated heating device is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figure 1 As shown, this embodiment provides a skid-mounted integrated heating device, including: a skid, a heating device fixedly connected to the skid, the heating device including a heat exchanger 3-1, the cold medium inlet of the heat exchanger 3-1 being connected to a cold medium inlet pipe, the cold medium outlet being connected to a cold medium outlet pipe, the hot medium inlet of the heat exchanger 3-1 being connected to a hot medium inlet pipe, and the hot medium outlet being connected to a hot medium outlet pipe; the ends of the cold medium inlet pipe, the cold medium outlet pipe, the hot medium inlet pipe, and the hot medium outlet pipe that are away from the heat exchanger 3-1 all extend out of the skid; a sampling component, a dosing component, and a hot medium power component are provided on the hot medium inlet pipe; a cold medium power component is provided on the cold medium inlet pipe.

[0025] This utility model adopts a skid-mounted integrated design, which enables the overall transportation and rapid installation of the equipment, significantly reducing on-site construction and installation time. The heat exchanger 3-1, in conjunction with the inlet and outlet pipelines for cold and hot media, can efficiently complete heat exchange to meet heating needs. Power components are installed on the cold and hot media inlet pipes respectively, which can accurately control the medium circulation flow and pressure, ensuring stable system operation. The sampling component on the hot media inlet pipe facilitates real-time monitoring of the medium status, and the dosing component can add chemicals in a timely manner to maintain system cleanliness, effectively preventing pipe scaling and equipment corrosion. The overall structure is compact and reasonable, which not only improves heating efficiency but also facilitates system maintenance and management. It is suitable for various heating scenarios and has strong practicality and economy.

[0026] The scheme was further optimized by setting up two sets of both the cold medium power assembly and the hot medium power assembly, which are connected in parallel to the cold medium inlet pipe and the hot medium inlet pipe, respectively.

[0027] The parallel redundant configuration, in which two sets of cold medium power components and hot medium power components are connected in parallel to their corresponding pipelines, ensures that the system can continue to operate even when a single power component is under maintenance or fails, greatly improving the reliability and continuity of the heating system. In addition, the parallel structure facilitates the rotation and maintenance of equipment, avoiding the shutdown of the entire system due to the failure of a single component, and effectively improving the practicality and ease of operation and maintenance of the heating device.

[0028] The scheme is further optimized. The cold medium power assembly includes a low-temperature circulating pump inlet valve 1-1, a low-temperature circulating pump 1-2, a low-temperature pump outlet check valve 1-3, and a low-temperature pump outlet valve 1-4. The low-temperature circulating pump inlet valve 1-1, the low-temperature circulating pump 1-2, the low-temperature pump outlet check valve 1-3, and the low-temperature pump outlet valve 1-4 are arranged sequentially along the flow direction of the cold medium.

[0029] The inlet valve 1-1 of the low-temperature circulating pump can cut off the inflow of cold medium during equipment maintenance or repair, providing safe operating conditions for the maintenance of the low-temperature circulating pump 1-2 and related pipelines. The low-temperature circulating pump 1-2, as the power source for cold medium circulation, can provide stable circulation power for the cold medium on the low-temperature side, ensuring that the flow rate and pressure of the cold medium on the low-temperature side meet the operating requirements of the heating system. The outlet check valve 1-3 of the low-temperature pump is installed at the outlet of the low-temperature circulating pump 1-2, which can effectively prevent the cold medium from flowing back when the circulating pump stops, avoiding damage to the impeller of the low-temperature circulating pump 1-2 or fluctuations in system pressure due to reverse flow of fluid, and ensuring the safe operation of the low-temperature circulating system. The outlet valve 1-4 of the low-temperature pump is located after the outlet check valve 1-3 of the low-temperature pump and can be used to adjust the circulation flow rate of the cold medium on the low-temperature side, so as to accurately control the heat exchange efficiency on the low-temperature side according to the changes in the actual heating load. This component, through the orderly arrangement and coordinated operation of its various parts, not only ensures the reliability and stability of the low-temperature side cold medium circulation system, but also facilitates the operation and maintenance management of the low-temperature side circulation system. At the same time, it reduces the energy loss of the cold medium during the circulation process and improves the overall operating efficiency of the heating device.

[0030] The scheme is further optimized. The heat medium power component includes a high-temperature end circulating pump inlet valve 2-7, a high-temperature end circulating pump 2-6, a high-temperature end pump outlet check valve 2-5, and a high-temperature end pump outlet valve 2-4. The high-temperature end circulating pump inlet valve 2-7, the high-temperature end circulating pump 2-6, the high-temperature end pump outlet check valve 2-5, and the high-temperature end pump outlet valve 2-4 are arranged sequentially along the flow direction of the heat medium.

[0031] The inlet valve 2-7 of the high-temperature circulating pump can precisely cut off the inflow of high-temperature cold medium during system maintenance or repair, ensuring the safe maintenance of the high-temperature circulating pump 2-6 and related pipelines. The high-temperature circulating pump 2-6, as the core power component, provides stable power for the circulation of cold medium under high-temperature conditions, ensuring that the high-temperature cold medium participates in the heat exchange process at the set flow rate and pressure, meeting high-load heating demands. The outlet check valve 2-5 of the high-temperature pump is installed at the outlet of the high-temperature circulating pump 2-6, effectively preventing backflow of the high-temperature cold medium when the circulating pump stops. This avoids thermal shock damage to the impeller of the high-temperature circulating pump 2-6 or sudden changes in system pressure due to reverse fluid flow, ensuring the operational safety of the equipment under high-temperature conditions. The outlet valve 2-4 of the high-temperature pump is located downstream of the outlet check valve 2-5, allowing for flexible adjustment of the circulation flow rate of the high-temperature cold medium according to actual heating load changes. Working in conjunction with the high-temperature circulating pump 2-6, it achieves precise control of the heat exchange efficiency on the high-temperature side. Through the orderly layout and functional coordination of its components, this component not only ensures the reliability and stability of the high-temperature cold medium circulation system in high-temperature environments, but also adapts to the characteristics of high-temperature media to reduce pipeline heat loss. At the same time, it facilitates the operation and maintenance management of high-temperature systems, significantly improving the energy utilization efficiency and operational continuity of heating devices under high-temperature conditions.

[0032] The scheme is further optimized by setting the sampling component in front of the dosing component. The sampling component includes a sampling pipeline connected to the inlet pipe of the hot medium. The sampling pipeline is connected in sequence to the sampling water valve 2-13 and the measuring instrument 2-14 along the flow direction of the hot medium. The end of the sampling pipeline is connected to the first sewage tank 2-15.

[0033] The sampling water valve 2-13 controls the sampling flow rate and process of the heat medium, facilitating safe and convenient sample acquisition by operators. The measuring instrument 2-14 monitors the physicochemical parameters of the heat medium in real time, such as pH value, conductivity, and temperature, providing data support for system operation status assessment and chemical dosing. The first wastewater tank 2-15 collects waste medium after sampling, preventing direct discharge of the heat medium and avoiding environmental pollution or safety hazards. This sampling component is located in front of the dosing component, allowing for precise monitoring of the initial state of the heat medium before the addition of chemicals. This ensures that the dosing component adds chemicals such as corrosion inhibitors and scale inhibitors as needed based on actual medium parameters, effectively preventing scaling in heat medium pipelines and equipment corrosion, improving heat exchange efficiency, and extending the service life of the heating device. Simultaneously, real-time monitoring data can promptly detect abnormal heat medium parameters, providing a basis for system fault diagnosis and maintenance, reducing operation and maintenance costs, and ensuring the stable and efficient operation of the heating system.

[0034] The scheme is further optimized. The dosing assembly includes a chemical tank 2-12, which is connected to the heat medium inlet pipe through a dosing pipeline. Two sets of dosing control components are connected in parallel on the dosing pipeline. The dosing control components include a dosing pump inlet valve 2-11, a dosing pump 2-10, a dosing pump outlet check valve 2-9, and a dosing pump outlet valve 2-8. The dosing pump inlet valve 2-11, the dosing pump 2-10, the dosing pump outlet check valve 2-9, and the dosing pump outlet valve 2-8 are arranged sequentially along the flow direction of the chemical in the dosing pipeline.

[0035] The reagent tank 2-12 is connected to the hot medium inlet pipe through the dosing pipeline. The two sets of dosing control components connected in parallel on the dosing pipeline each include a dosing pump inlet valve 2-11, a dosing pump 2-10, a dosing pump outlet check valve 2-9, and a dosing pump outlet valve 2-8, and each component is arranged sequentially along the direction of reagent flow. This structure has the following significant advantages and technical effects: The reagent tank 2-12 can store corrosion inhibitors, scale inhibitors, and other reagents, and is connected to the heat medium inlet pipe through the dosing pipeline, providing a carrier for the reagent injection system; the parallel design of the two sets of dosing control components forms a redundant configuration. When one set of components needs maintenance or fails, the other set can maintain normal reagent dosing, ensuring continuous corrosion and scale prevention treatment of the system and improving the reliability of the heating device; in each set of dosing control components, the dosing pump inlet valve 2-11 can control the flow of reagent into the dosing pump 2-10, facilitating equipment maintenance; the dosing pump 2-10 provides power for reagent injection, ensuring accurate dosing of reagents according to the set dosage; the dosing pump outlet check valve 2-9 can prevent reagent backflow, avoiding reagent recirculation back to the reagent tank 2-12 or affecting the normal operation of the dosing pump 2-10; the dosing pump outlet valve 2-8 can flexibly adjust the reagent flow rate, adding reagents as needed according to changes in system load. Through parallel redundancy design and orderly coordination of various components, this component not only achieves continuous and accurate dosing of reagents, but also dynamically adjusts the dosage according to the parameters of the heat medium, effectively preventing scaling in heat medium pipelines and corrosion of equipment, improving heat exchange efficiency, extending the service life of heating devices, and facilitating component rotation, inspection and maintenance, thus reducing system operation and maintenance costs.

[0036] The scheme is further optimized by connecting a drain pipe to the heat medium outlet pipe, a drain valve 2-16 to the drain pipe, and a second drain pool 2-17 to the end of the drain pipe.

[0037] The drain pipe connects to the heat medium outlet pipe, allowing for the timely discharge of impurities, dirt, or deposited pollutants generated during the heat medium circulation process. This prevents impurities from accumulating in the heat medium system, which could lead to pipe blockage or reduced heat exchange efficiency. The drain valve 2-16, installed on the drain pipe, precisely controls the opening and closing of the drain operation, facilitating regular or on-demand draining based on system operating conditions. This ensures draining efficiency while preventing unnecessary loss of heat medium. The second drain tank 2-17, serving as the end-of-pipe collection device, centrally collects the heat medium and impurities discharged during the draining process, preventing direct wastewater discharge that could cause environmental pollution or safety hazards. It also facilitates unified treatment or monitoring of the discharged medium. This structure, through the coordinated operation of the drain pipe, drain valve 2-16, and second drain tank 2-17, not only achieves convenient draining and impurity removal from the heat medium system, effectively maintaining the cleanliness of the heat exchange equipment, improving heat exchange efficiency, and extending the service life of the heating device, but also meets environmental protection requirements through centralized draining design, reduces system maintenance costs, and ensures the stable and efficient operation of the heating system.

[0038] The scheme is further optimized as follows: a low-temperature hot water outlet valve 1-5 is connected to the cold medium outlet pipe; a low-temperature heat exchange inlet valve is connected to the end of the cold medium inlet pipe near heat exchanger 3-1; a high-temperature heat exchange inlet valve is connected to the end of the hot medium inlet pipe near heat exchanger 3-1, and a hot medium inlet valve 2-18 is connected to the end away from heat exchanger 3-1; a high-temperature hot water outlet valve 2-3 is connected to the end of the hot medium outlet pipe near heat exchanger 3-1, and a hot medium discharge valve 2-19 is connected to the end away from heat exchanger 3-1.

[0039] The low-temperature hot water outlet valve 1-5 connected to the cold medium outlet pipe can control the output flow rate of the cold medium after heat exchange on the low-temperature side, which facilitates the adjustment of the heating supply according to the heating demand on the user side. The low-temperature heat exchange inlet valve on the cold medium inlet pipe near the heat exchanger 3-1 can control the flow rate of the cold medium entering the heat exchanger 3-1, and cooperates with the low-temperature hot water outlet valve 1-5 to achieve precise control of the heat exchange process on the low-temperature side. The high-temperature heat exchange inlet valve on the hot medium inlet pipe near the heat exchanger 3-1 can control the flow rate of the hot medium into the heat exchanger 3-1, while the hot medium inlet valve 2-18 far from the heat exchanger 3-1 is used to control the on / off of the hot medium entering the heating device from the heat source side. The two valves work together to adjust the input of the hot medium according to the change of the heat source load. The high-temperature hot water outlet valve 2-3 on the hot medium outlet pipe near the heat exchanger 3-1 is used to control the flow rate of the hot medium out of the heat exchanger 3-1, while the hot medium discharge valve 2-19 far from the heat exchanger 3-1 can cut off the discharge path of the hot medium during system maintenance or shutdown. This structure, through the orderly arrangement of various valves, enables flow control and on / off management of cold and hot media at the inlet and outlet of heat exchanger 3-1 and the main pipeline of the system. It not only facilitates the isolation of cold and hot media circulation loops by closing the corresponding valves during system maintenance to ensure maintenance safety, but also dynamically adjusts the media flow according to the actual heating load to optimize heat exchange efficiency. At the same time, the precise control of valves reduces energy loss during media transportation, thereby improving the stability and economy of the heating device.

[0040] The scheme is further optimized so that the cold medium inlet pipe and the cold medium outlet pipe are connected to a cold medium bypass at the end near the heat exchanger 3-1, and a low temperature bypass valve 1-6 is installed on the cold medium bypass; the hot medium inlet pipe and the hot medium outlet pipe are connected to a hot medium bypass at the end near the heat exchanger 3-1, and a high temperature bypass valve 2-2 is installed on the hot medium bypass.

[0041] The cold medium inlet pipe and the cold medium outlet pipe are connected to the cold medium bypass at the end near the heat exchanger 3-1, and a low-temperature bypass valve 1-6 is installed on the cold medium bypass. The hot medium inlet pipe and the hot medium outlet pipe are connected to the hot medium bypass at the end near the heat exchanger 3-1, and a high-temperature bypass valve 2-2 is installed on the hot medium bypass. This structure has the following significant advantages and technical effects: The combination of the cold medium bypass and the low-temperature bypass valve 1-6 can open the bypass channel when the heat exchanger 3-1 is under maintenance or malfunctions, allowing the cold medium to bypass the heat exchanger 3-1 and circulate directly between the cold medium inlet pipe and the cold medium outlet pipe, avoiding the shutdown of the entire heating system due to the maintenance of the heat exchanger 3-1, and ensuring the continuity of heating. The setting of the hot medium bypass and high-temperature end bypass valve 2-2 can adjust the bypass flow when the hot medium flow demand changes. For example, under low load conditions, part of the hot medium can flow back directly to the hot medium outlet pipe through the hot medium bypass, reducing the flow of hot medium through heat exchanger 3-1 and avoiding energy waste. The two sets of bypass systems can flexibly adjust the distribution ratio of cold and hot medium between the main circuit and the bypass through the on / off control of the bypass valves, so as to achieve precise adjustment of the heat exchange efficiency of heat exchanger 3-1. At the same time, it can serve as an emergency channel to maintain system operation when the main circuit pipeline or valve is blocked, effectively improving the operational reliability and operating condition adaptability of the heating device and reducing system operation and maintenance costs.
