Description

Technical Field

[0001] This utility model relates to the field of steam waste heat recovery technology, specifically to a steam waste heat recovery and utilization device. Background Technology

[0002] Steam generation depends on fuel combustion or electrical energy consumption to heat water to a high temperature and high pressure state. In essence, it is an energy carrier that carries a large amount of heat energy.

[0003] When steam is used in industry, direct discharge not only wastes energy but also has a negative impact on the environment, either directly or indirectly. After steam completes its primary core use, although its temperature and pressure will decrease, it still retains heat and physical properties that can be converted into secondary energy. These properties are highly compatible with the large amount of "secondary energy demand" in daily life.

[0004] Now, a steam waste heat recovery and utilization device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a steam waste heat recovery and utilization device to solve the problem mentioned in the background art that direct emissions not only waste energy, but also indirectly or directly cause negative impacts on the environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steam waste heat recovery and utilization device, including a tank body, four sets of support legs are fixedly connected to the bottom end of the tank body, and a waste heat recovery and utilization structure is provided inside the tank body;

[0007] The waste heat recovery and utilization structure includes a fixed base, which is fixedly connected to the top of the tank body. An air inlet is provided at the top left side of the tank body. A condensing coil is fixedly connected inside the fixed base. An air outlet is provided at the top of the condensing coil. An inner cylinder is provided inside the fixed base. A top cover is provided at the top of the inner cylinder.

[0008] As a further technical solution of this utility model, the condenser coil, the fixed seat, and the air outlet are internally connected, the outer diameter of the top cover matches the inner diameter of the fixed seat, the top cover fits into the fixed seat, and the top cover moves up and down inside the fixed seat.

[0009] As a further technical solution of this utility model, an installation box is fixedly connected to the middle of the tank body, an inlet is opened at the top of the installation box, multiple sets of activated carbon boxes are arranged inside the installation box, an outlet is opened at the bottom of the installation box, a collection chamber is fixedly connected to the bottom of the tank body, and a drain is fixedly connected to the bottom of the right side of the tank body.

[0010] As a further technical solution of this utility model, the liquid inlet, activated carbon box, and liquid outlet are internally connected, the liquid collection chamber and liquid drain are internally connected, and multiple sets of activated carbon boxes are evenly arranged.

[0011] As a further technical solution of this utility model, a filter tube is fixedly connected to the left side of the air inlet, an insulation sleeve is fitted on the outside of the filter tube, a limit ring is fixedly connected inside the filter tube, and a filter basket is installed inside the limit ring.

[0012] As a further technical solution of this utility model, the size of the filter basket matches the limiting ring, the inner diameter of the insulation sleeve matches the outer diameter of the filter tube, and the insulation sleeve is tightly fitted to the filter tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the steam waste heat recovery and utilization equipment not only realizes the heating of the medium or items inside the inner cylinder, but also realizes the recovery of steam condensate, and also realizes the interception of large particulate matter carried in the steam;

[0014] (1) By setting up an air inlet, a fixed seat, a condensing coil, an air outlet, an inner cylinder and a top cover, the steam waste heat would cause energy waste if it were directly discharged. When in use, the steam enters the condensing coil through the air inlet, and the heat is transferred to the fixed seat through the condensing coil. The fixed seat is equipped with an inner cylinder, thereby heating the medium or items inside the inner cylinder, avoiding direct contact between the steam and the items to be heated. At the same time, the reuse of the steam waste heat reduces the dependence on other heat sources and reduces energy consumption and operating costs.

[0015] (2) By setting up an installation box, liquid inlet, activated carbon box, liquid outlet, liquid collection chamber and liquid drain, when in use, steam passes through the condenser coil and is converted from gas to liquid. Due to the process, a small amount of volatile organic compounds, solvent residues, grease or odor substances will be mixed into the steam. The condensed liquid enters the activated carbon box. Activated carbon has a strong adsorption capacity and can effectively adsorb organic pollutants, odors, pigments and some heavy metal ions in the water, thereby purifying the liquid. The purified liquid enters the liquid collection chamber and can be discharged from the liquid drain. It can be reused as boiler feedwater, production process water or cleaning water, etc., reducing the consumption of fresh tap water and reducing water resource costs.

[0016] (3) By setting up filter tubes, limiting rings, filter baskets and insulation sleeves, steam often carries various impurities during the generation or transportation process. When hard particles in the steam flow with the high-speed airflow, they will cause scouring and wear on the inner walls and pipes of subsequent equipment. Long-term operation will lead to equipment damage or blockage. When in use, by fixing the filter tubes to the left side of the air inlet, the filter basket can effectively intercept large particles carried in the steam, thereby protecting the subsequent equipment.

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] Example: Please refer to Figure 1-4 A steam waste heat recovery and utilization device includes a tank 1, four sets of support legs 2 are fixedly connected to the bottom end of the tank 1, and a waste heat recovery and utilization structure is provided inside the tank 1.

[0024] Please see Figure 1-4 A steam waste heat recovery and utilization device also includes a waste heat recovery and utilization structure, which includes a fixed base 4, the fixed base 4 is fixedly connected to the top of the tank body 1, the top left side of the tank body 1 is provided with an air inlet 3, the fixed base 4 is fixedly connected to a condensing coil 5, the top of the condensing coil 5 is provided with an air outlet 6, the air inlet 3 is provided with an inner cylinder 7, and the top of the inner cylinder 7 is provided with a top cover 8.

[0025] The condenser coil 5, the fixed base 4, and the air outlet 6 are internally connected. The outer diameter of the top cover 8 matches the inner diameter of the fixed base 4. The top cover 8 fits into the fixed base 4 and moves up and down inside the fixed base 4.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, direct discharge of steam waste heat would result in energy waste. During use, steam enters the condenser coil 5 through the air inlet 3, and the heat is transferred to the fixed base 4 through the condenser coil 5. The fixed base 4 is equipped with an inner cylinder 7, thereby heating the medium or items inside the inner cylinder 7, avoiding direct contact between steam and the items to be heated. At the same time, the reuse of steam waste heat reduces dependence on other heat sources and reduces energy consumption and operating costs.

[0027] An installation box 9 is fixedly connected to the middle of the inside of the tank body 1. The top of the installation box 9 is provided with a liquid inlet 10. Multiple sets of activated carbon boxes 11 are installed inside the installation box 9. The bottom of the installation box 9 is provided with a liquid outlet 12. A liquid collection chamber 13 is fixedly connected to the bottom of the inside of the tank body 1. A liquid drain 14 is fixedly connected to the bottom of the right side of the tank body 1. The liquid inlet 10, activated carbon boxes 11, and liquid outlet 12 are internally connected. The liquid collection chamber 13 and liquid drain 14 are internally connected. The multiple sets of activated carbon boxes 11 are evenly arranged.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, steam passes through the condenser coil 5 and is converted from gas to liquid. Due to the process, a small amount of volatile organic compounds, solvent residues, grease, or odorous substances may be mixed into the steam. The condensed liquid enters the activated carbon box 11. Activated carbon has extremely strong adsorption properties and can effectively adsorb organic pollutants, odors, pigments, and some heavy metal ions in the water, thereby purifying the liquid. The purified liquid enters the collection tank 13 and can be discharged from the drain port 14. It can then be reused as boiler feedwater, process water, or cleaning water, reducing the consumption of fresh tap water and lowering water resource costs.

[0029] A filter tube 15 is fixedly connected to the left side of the air inlet 3. An insulation sleeve 18 is fitted on the outside of the filter tube 15. A limit ring 16 is fixedly connected inside the filter tube 15. A filter basket 17 is installed inside the limit ring 16. The size of the filter basket 17 matches the size of the limit ring 16. The inner diameter of the insulation sleeve 18 matches the outer diameter of the filter tube 15. The insulation sleeve 18 and the filter tube 15 are tightly fitted together.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, steam often carries various impurities during its generation or transportation. When hard particles in the steam flow with the high-speed airflow, they can cause erosion and wear on the inner walls and pipes of downstream equipment. Long-term operation can lead to equipment damage or blockage. In use, by fixing the filter tube 15 to the left side of the air inlet 3, the filter basket 17 can effectively intercept large particles carried in the steam, thereby protecting downstream equipment.

[0031] Working Principle: In use, this invention addresses the energy waste caused by directly discharging waste steam. Firstly, steam enters the condenser coil 5 through the inlet 3, and heat is transferred to the mounting base 4 via the condenser coil 5. The mounting base 4 contains an inner cylinder 7, which heats the medium or items inside the inner cylinder 7, preventing direct contact between the steam and the heated items. Simultaneously, the reuse of waste steam reduces reliance on other heat sources, lowering energy consumption and operating costs. Secondly, after passing through the condenser coil 5, the steam transforms from a gas into a liquid. Due to the process, a small amount of volatile organic compounds, solvent residues, grease, or odorous substances may be mixed into the steam. The condensed liquid enters the activated carbon box 11, where activated carbon possesses strong adsorption properties. It can effectively adsorb organic pollutants, odors, pigments and some heavy metal ions in water, thereby purifying the liquid. The purified liquid enters the collection tank 13 and can be discharged from the drain port 14. It can be reused as boiler feedwater, production process water or cleaning water, etc., reducing the consumption of fresh tap water and reducing water resource costs. During the generation or transportation of steam, it often carries various impurities. When hard particles in steam flow with the high-speed airflow, they will cause scouring and wear on the inner walls and pipes of subsequent equipment. Long-term operation will lead to equipment damage or blockage. When in use, by fixing the filter tube 15 to the left side of the air inlet 3, the filter basket 17 can effectively intercept large particles carried in the steam, thereby protecting the subsequent equipment.
