Description

Technical Field

[0001] This utility model relates to the technical field of hot cement cooling equipment, and in particular to a novel heat transfer composite cement cooler. Background Technology

[0002] In the modernization of the cement industry, finished product temperature control has become a core challenge restricting technological upgrades. Due to the physical characteristics of energy conversion in the grinding process, the temperature of cement exiting the mill is generally as high as 100-200℃, and even after transportation and storage, it remains above 80℃ upon leaving the factory. This sustained high temperature triggers multiple chain reactions: aging of conveying equipment, frequent false setting of cement due to gypsum dehydration, brittleness and breakage of packaging bags under high temperatures, and humid and hot environments in storage promoting cement particle agglomeration, severely affecting product homogeneity. Even more challenging is the fact that in special applications such as airport engineering, nuclear power engineering, and deep-sea infrastructure construction, the initial cement temperature must be strictly controlled below 65℃, placing almost stringent requirements on existing cooling technologies.

[0003] Current industry-standard cooling solutions primarily rely on single-medium heat exchange with air or water, achieving temperature drops of only 30-60°C. The inherent drawback of air cooling is its low specific heat capacity; to achieve effective cooling, an extremely large ventilation system is required, leading to a surge in equipment footprint and energy costs.

[0004] In contrast, the spiral lift cooler in water-cooling technology, which uses a water curtain on the outer wall of the cylinder for heat exchange, has become the mainstream in industrial applications, but it has exposed three technical bottlenecks: First, the precision-machined cylinder must ensure concentricity at the 0.05mm level, and the equipment manufacturing cost is 2-3 times that of conventional equipment; second, the continuously operating spiral lift device consumes 0.5-1 kWh of electricity per ton, while the water cooling system consumes more than 0.5 cubic meters of water per ton, resulting in high operating costs. Moreover, the cooling efficiency of the equipment decreases exponentially with the accumulation of scale, and the heat transfer coefficient drops by more than 40% after 6 months of operation.

[0005] Improved horizontal spiral coolers, exemplified by CN201753324U and CN101891061A, have improved heat exchange efficiency to some extent through structural innovations in hollow shafts and spiral blades. However, they have failed to overcome the fundamental limitations of traditional technologies: high installation, manufacturing, and operating costs, large equipment footprint, and low heat exchange efficiency. More importantly, the single heat exchange mode employed in existing cooling systems limits heat exchange efficiency and makes it difficult to cope with temperature gradient changes in cement particles during transport. This often results in rapid surface cooling while continuous heat accumulation inside, ultimately leading to uneven temperature distribution in the finished product.

[0006] Patent CN215288544U discloses a uniformly fed cement cooling device, comprising a cooling chamber with inlet and outlet hoppers at the upper and lower ends. Heat dissipation fins are fixedly installed on the outer wall of the cooling chamber. Heat exchange plates are arranged at an incline on both sides of the cooling chamber, and heat exchange components are installed on the heat exchange plates. Heat exchange tubes are embedded within the heat exchange components. Water inside the heat exchange tubes absorbs heat from the cement, thereby cooling the cement. Although this technology utilizes both air and water cooling, the heat exchange efficiency is relatively low because both are sensible heat exchanges. Furthermore, this technology has a fatal flaw: the heat exchange tubes carrying the flowing water are placed inside the hot cement to be cooled. Cement particles have a certain hardness, and after the heat exchange tubes have been running for a period of time, they may leak due to wear. The amount of cooling water is large, and if it leaks into the cement, it can react chemically with the cement, causing a major production accident. Therefore, how to isolate the cooling medium from the cement to be cooled and how to quickly and effectively transfer heat is a pressing problem that needs to be solved in this field.

[0007] Faced with increasingly stringent environmental regulations and energy efficiency standards, traditional cooling technologies are showing their limitations. The industry urgently needs to develop a composite, high-efficiency cooling device that can achieve a stable temperature drop of at least 80°C within a limited space, while controlling the energy consumption for cooling cement to below 0.3 kWh / t and eliminating concerns about production accidents. This technological breakthrough will not only improve cement quality but will also have a profound impact on promoting the green transformation of the building materials industry. Summary of the Invention

[0008] In order to overcome the problems of low cooling efficiency, high energy consumption, large footprint and potential production accidents in the existing technology, this utility model provides a heat transfer composite cement cooler.

[0009] The technical solution adopted to achieve the above objectives is: a heat transfer composite cement cooler, comprising:

[0010] a) Independent hot cement flow sealing cavity and cooling cavity, wherein the cement flow sealing cavity is provided with a cement inlet at the top and a cement outlet at the bottom, and the cooling cavity is provided with an air inlet on the lower side wall and an air outlet at the top;

[0011] b) The heat transfer assembly mainly consists of an evaporation unit and a condensation unit forming a closed vacuum structure. The evaporation unit contains a heat transfer medium and is located inside a cement flow-sealed cavity. The condensation unit is located inside a cooling cavity.

[0012] c) A water circulation system, including a water tank located at the bottom or below the cooling chamber, a water pump connected to the water tank in sequence via pipelines, and a spray device at the top of the condensation unit;

[0013] d) A hot cement distribution device installed on the upper part of the cement flow sealing cavity;

[0014] e) A cement conveying power unit installed on the outer wall of the cement flow sealed cavity;

[0015] f) A dust removal device installed on the side of the evaporation unit;

[0016] g) An axial flow fan or induced draft fan installed at the air outlet.

[0017] Furthermore, the installation elevation of the evaporation unit is lower than that of the condensation unit.

[0018] Furthermore, the cement conveying power device is at least one of an acoustic device, a mechanical vibration device, a pulse jet device, or a compressed air conveying device.

[0019] Furthermore, the outer wall of the heat exchange surface of the evaporation unit is provided with a wear-resistant and corrosion-resistant coating.

[0020] Furthermore, the amount of heat medium charged in the heat transfer component is 5%-100% of the volume of the evaporation unit.

[0021] Furthermore, the vacuum level within the heat transfer assembly is 10. -4 -10 -1 Pa.

[0022] Furthermore, the water tank is equipped with a water supply pipeline, a chemical dosing device, and a sewage discharge pipeline.

[0023] Furthermore, the water supply pipeline, the chemical dosing device, and the sewage discharge pipeline are all equipped with automatic control devices.

[0024] Furthermore, the axial flow fan or induced draft fan and the water pump are equipped with frequency conversion control devices.

[0025] Furthermore, it also includes an intelligent control system, comprising: a temperature sensor and a cement flow rate monitoring probe installed within the cement flow sealed cavity; temperature sensors installed on the heat exchange surfaces of the evaporation and condensation units; a temperature sensor, a water level sensor, a water quality monitoring probe, and a PLC controller installed within the water tank. The PLC controller dynamically adjusts the fan speed, spray water volume, and spray pressure based on the cement temperature, condensation unit temperature difference, and cement flow rate feedback from the sensors. The PLC controller also controls valves to perform water replenishment, chemical dosing, and wastewater discharge operations based on feedback from the temperature and water level sensors within the water tank and water quality detection.

[0026] The beneficial effects of this utility model are as follows: 1. Superior cooling capacity: Through theoretical calculations, it can cool cement at a high temperature of 200℃ to 70℃, a temperature reduction of 130℃, far exceeding traditional equipment (30-60℃). The principle is that the water circulation system sprays water onto the condensing unit through a spray device, forming a water film on the surface of the condensing unit. Through water flow heat transfer and water evaporation phase change heat transfer, the condensing unit is subjected to enhanced cooling. Combined with air convection in the cooling sealed cavity and phase change (or convection) heat transfer of the heat transfer medium in the heat transfer components, a three-in-one composite cooling system is formed, which can improve the unit heat exchange efficiency by more than 40%, and is suitable for ultra-large-scale production lines.

[0027] 2. Energy-saving, water-saving, and environmentally friendly: Due to the absence of a spiral lifting device and an oversized ventilation system, the power consumption per ton of equipment is only 0.15 kWh / t, a reduction of 60%-85% compared to traditional spiral lifting systems (0.5-1 kWh / t) and water-air combined systems (0.4-0.5 kWh / t). Water consumption is only 0.05 m³ / t, with circulating water usage only about 1 / 10 of that of traditional spiral lifting systems, resulting in significant water savings. The fully enclosed design achieves "zero dust and low steam emissions," completely solving the environmental problems associated with traditional equipment.

[0028] 3. The device operates intelligently and stably. The axial flow fan or induced draft fan and water pump adopt variable frequency control technology to avoid unnecessary energy loss due to temperature fluctuations. The device monitors the temperature, heat transfer medium flow rate, and condensation unit temperature difference at different detection points in real time. Through PLC control program, it automatically adjusts the fan speed, water spray pressure, and water spray volume to ensure long-term stable cooling effect.

[0029] 4. The device is compact and occupies a small area. Due to the elimination of the need for a large water circulation system (such as a cooling tower or water storage tank) and the improvement of heat exchange efficiency, this device can reduce infrastructure investment by more than 30% and reduce the floor space by 30%-50% compared with traditional devices.

[0030] 5. Low maintenance cost, no mechanical stirring parts, and the overall equipment has a service life of over 10 years. Attached Figure Description

[0052] Example 1: A heat transfer composite cement cooler, such as Figures 1-3 As shown, it includes: a hot cement flow sealing cavity 1 and a cooling cavity 2, which are independent of each other and arranged side by side.

[0053] The cement flow sealed cavity 1 provides a cooling space for hot cement. It has a cement inlet 3 at the top and a cement outlet 4 at the bottom. A uniform distribution device 14 for evenly distributing hot cement is located in the upper part of the cavity, and a cement conveying power device 15 to promote the flow of hot cement is located on the outer wall of the cavity. The cement conveying power device can be one or a combination of several of the following: an acoustic device, a mechanical vibration device, a pulse jet device, or a compressed air conveying device. This embodiment uses an acoustic device. To improve wear and corrosion resistance, a wear-resistant and corrosion-resistant layer is also provided on the inner wall of the cement flow sealed cavity.

[0054] The cooling chamber 2 is a place for the flow of cooling medium. An air inlet 5 is opened on the bottom side wall of the cooling chamber and an air outlet 6 is set at the top. Two axial flow fans 17 are provided at the air outlet to force air convection through the cooling chamber.

[0055] The heat from the hot cement is exchanged with a cooling medium through a heat transfer assembly, which consists of an evaporation unit 8 and a condensation unit 9 forming a closed vacuum structure. The evaporation unit 8 contains the heat transfer medium and is located inside the cement flow-through sealed cavity 1, while the condensation unit 9 is located inside the cooling cavity 2. The evaporation unit 8 is installed at a lower elevation than the condensation unit 9, allowing the heat transfer medium to circulate using gravity. To further improve the heat exchange efficiency of the heat transfer assembly, a vacuum of 10⁻⁵ is applied inside the assembly. -4 Pa. Furthermore, a ceramic wear-resistant and corrosion-resistant coating is provided on the outer wall of the heat exchange surface of the evaporation unit 8 to improve the service life of the evaporation unit and reduce the maintenance cost of the heated surface. To prevent cement from adsorbing on the heat exchange surface of the evaporation unit 8 and forming a heat insulation layer, a dust removal device 16 is also provided at the heat exchange surface. The dust removal device can use sonic cleaning, mechanical vibration cleaning, or air cannon cleaning. In this embodiment, a mechanical vibration cleaning device is used. The heat transfer medium in the heat exchange assembly can be water, ethanol, acetone, or Freon, etc. The amount of heat transfer medium charged is determined by thermal calculation based on the amount of heat exchange. In this embodiment, the amount of heat transfer medium charged in the heat transfer assembly is 5% of the evaporation unit volume.

[0056] The water circulation system includes a water tank 10 located below the cooling chamber 2, a water pump 12 connected to the water tank via a pipe 11, and a spray device 13 located above the condensing unit 9. The spray device forms a uniform water film on the surface of the condensing unit to enhance heat exchange. The water tank is equipped with a water replenishment pipe 18, a chemical dosing device 19, and a sewage discharge pipe 20. Water replenishment, chemical dosing, and sewage discharge operations are performed based on the water level, temperature, and water quality analysis results of the water tank.

[0057] The device is also equipped with an intelligent control system, including: frequency converters for the axial flow fan and water pump; a temperature sensor 21 and a cement flow rate monitoring probe 22 installed in the cement flow sealed cavity; a temperature sensor 23 and a temperature sensor 24 installed on the surface of the evaporation unit and the condensation unit; a temperature sensor 25, a water level sensor 26, and a water quality monitoring probe 27 installed in the water tank; and a PLC controller 28 that is linked to the frequency converter axial flow fan, water pump, and various pipeline valves.

[0058] The PLC controller dynamically adjusts the fan speed, spray water volume, and spray pressure based on the cement temperature, condensation unit temperature difference, and cement flow rate fed back by sensors. The PLC controller also performs water replenishment, chemical dosing, and wastewater discharge operations based on feedback from temperature and water level sensors in the water tank and water quality testing results.

[0059] The working process of this device is as follows: High-temperature cement enters the cement flow sealed cavity through the top cement inlet. Under the action of the cement uniform distribution device, a uniform material layer is formed. Under the action of the cement conveying power device, the cement material layer flows through the evaporation unit, making full contact with the heat exchange surface of the evaporation unit. The heat released by the hot cement is transferred to the heat medium through the wall of the evaporation unit. After the heat medium absorbs heat and vaporizes, the steam enters the condensation unit through the vacuum channel. In the condensation unit, the steam releases latent heat and liquefies through a triple cooling mechanism: the sprayed water film absorbs most of the heat through sensible heat exchange, the air convection driven by the axial flow fan further enhances the heat exchange, and at the same time, the latent heat released by the phase change of the heat medium is transferred to the cooling medium through the wall of the condensation unit. The liquefied heat medium flows back to the evaporation unit by gravity, forming a closed loop. After absorbing heat, the cooling water flows into the water tank for recycling. The water supply pipeline, the chemical dosing device, and the sewage discharge pipeline maintain water quality stability.

[0060] The intelligent control system integrates multiple sensors to collect real-time data on cement temperature, flow rate, condensation unit temperature difference, water tank temperature, water level, and water quality. It dynamically adjusts fan speed, spray pressure, cleaning frequency, and water replenishment, chemical dosing, and sewage discharge operations. The frequency conversion control of the axial flow fan and water pump is matched to real-time heat load changes, avoiding energy waste. The cleaning device maintains the cleanliness of the heat transfer surface through periodic vibration or pulse jet cleaning, preventing an increase in thermal resistance.

[0061] The advantages of this device stem from the synergistic effect of multiple heat transfer mechanisms: spray water cooling directly absorbs heat through sensible heat exchange; air convection breaks the thermal boundary layer to improve heat transfer efficiency; and the phase change of the heat transfer medium utilizes latent heat to significantly increase the unit heat transfer. The vacuum environment reduces heat conduction loss through gas molecules and simultaneously lowers the boiling point of the heat transfer medium to accelerate the phase change process. The closed-loop water system design significantly reduces water consumption, and the fully sealed structure prevents dust escape, meeting environmental protection requirements. The intelligent control system not only maintains stable system operation but also maximizes energy savings.

[0062] Theoretical calculations show that this device can cool cement from 200℃ to 70℃, a temperature reduction of 130℃. Electricity and water consumption per ton of cement are reduced to 0.15 kWh and 0.05 m³, respectively. Overall energy efficiency is improved by 60%-85% compared to traditional equipment, water savings reach 80%-90%, and the footprint is reduced by 30%-50%.

[0065] The cooling chamber 2 has an air inlet 5 on its bottom side wall and an air outlet 6 on its top. A fan 17 is provided at the air outlet to force air convection through the cooling chamber.

[0066] The heat from the hot cement is exchanged with a cooling medium through a heat transfer assembly. The heat transfer assembly consists of an evaporation unit 8 and a condensation unit 9 connected by a sealed pipe 7, forming a closed vacuum structure. The evaporation unit 8 contains the heat transfer medium and is located inside the cement flow sealed cavity 1, while the condensation unit 9 is located inside the cooling cavity 2. To further improve the heat exchange efficiency of the heat transfer assembly, a vacuum of 10⁻⁶ is applied inside the heat transfer assembly. -1 Pa. Furthermore, a silicon carbide wear-resistant and corrosion-resistant coating is provided on the outer wall of the heat exchange surface of the evaporation unit to improve the service life of the evaporation unit and reduce the maintenance cost of the heated surface. To prevent cement from adsorbing on the heat exchange surface of the evaporation unit 8 and forming a heat insulation layer, a dust removal device 16 is also provided at the heat exchange surface. The dust removal device can use acoustic dust removal, mechanical vibration dust removal, or air cannon dust removal; in this embodiment, an acoustic dust removal device is used. The heat transfer medium in the heat exchange assembly can be water, ethanol, acetone, or Freon, etc., and the amount of heat transfer medium charged in the heat transfer assembly is 100% of the volume of the evaporation unit.
