Description

Technical Field

[0001] This utility model relates to the field of waste heat collection technology, specifically to an input pretreatment device for waste heat collection. Background Technology

[0002] In industrial production, high-temperature waste heat resources are widely found in boiler flue gas and metallurgical furnace exhaust gases, and their recovery and utilization can significantly improve energy efficiency. However, high-temperature gases often contain impurities such as dust, sulfides, and solid particles. Existing waste heat collection devices mostly connect directly to the gas for heat exchange. After these impurities enter the device with the airflow, they easily deposit on the heat exchange surface, forming scale and reducing heat transfer efficiency. At the same time, the high-speed scouring of hard particles can wear down equipment components, and corrosive impurities can cause material degradation, leading to a shortened device lifespan, a surge in maintenance costs, and hindering the stable operation of the waste heat recovery system.

[0016] A connecting flange is fixedly connected to the connection between the second connecting pipe and the air inlet pipe, and the first connecting pipe is fixedly connected to the gas inlet through the connecting flange.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model provides an input pretreatment device for waste heat collection. The raw materials to be pretreated are fed into the pretreatment tank through the feed inlet. Then, high-temperature gas is introduced into the liquid separation mechanism to remove liquid substances such as water from the high-temperature gas.

[0019] 2. This utility model provides an input pretreatment device for waste heat collection. By injecting high-temperature mixed gas into the device through the mixed gas inlet, the gas will condense when it comes into contact with the guide plate and umbrella plate. The condensed liquid droplets will drip into the liquid collection tank and be discharged through the drain port. The separated gas is transmitted to the next process through the connecting pipe 2, thereby preventing water droplets in the gas from entering the heating tank and corroding it.

[0020] 3. This utility model provides an input pretreatment device for waste heat collection. The separated gas is introduced into the solid separation chamber through the inlet pipe. Large particles are filtered out by a filter screen, and small particles are filtered out by a dust adsorption plate. Particles filtered out by the baffle slide down to the left side of the filter screen due to its inclination. By pulling out the baffle, the particles fall into the collection box due to gravity, thus being discharged. The purified high-temperature gas enters the heating tank through the gas inlet. The material to be pretreated is injected into the pretreatment tank through the feed inlet. The liquid inside the pretreatment tank is indirectly heated by heating the liquid inside the heat-conducting tank, resulting in more uniform heating and preventing localized overheating. The connection is separated by a connecting flange, allowing for flexible adjustment of whether to remove water or solid impurities first, depending on the content of liquid and solid impurities in the mixed gas.

[0033] 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.

[0034] like Figure 1-5 As shown, this utility model has the following three specific embodiments.

[0035] Example 1

[0036] This utility model provides an input pretreatment device for waste heat collection, including a base 11, a heating tank 12 fixedly connected to the top of the base 11, a heat-conducting tank 13 fixedly connected inside the heating tank 12, a pretreatment tank 14 opened inside the heat-conducting tank 13, a feed inlet 15 fixedly connected to the upper right side of the pretreatment tank 14, a discharge outlet 16 fixedly connected to the lower right side of the pretreatment tank 14, a gas inlet 17 fixedly connected to the left side of the heating tank 12, the gas inlet 17 penetrating through the left side plate of the base 11 and extending into the interior of the base 11, and a gas outlet 18 fixedly connected to the top of the base 11.

[0037] It also includes a solid particle separation mechanism 2, a collection mechanism 3, and a liquid separation mechanism 4;

[0038] The solid particle separation mechanism 2 is located on the left side of the base 11 and is used to remove dust impurities from the high-temperature gas.

[0039] The collection mechanism 3 is located at the bottom of the solid particle separation mechanism 2 and is used to discharge the dust and impurities intercepted by the collection mechanism 3.

[0040] The liquid separation mechanism 4 is located on the left side of the solid particle separation mechanism 2 and is used to remove liquid impurities from the high-temperature gas.

[0041] In this embodiment, as Figure 1 As shown, the raw materials requiring pretreatment are fed into the pretreatment tank 14 through the feed inlet 15. Then, high-temperature gas is introduced into the liquid separation mechanism 4 to remove liquid substances such as water from the high-temperature gas. If droplets are allowed to enter the heating tank 12, the local temperature may drop sharply due to the heat absorption of the droplets during evaporation, or the corrosive components in the droplets may exacerbate equipment corrosion. After dehumidification, solid particles in the high-temperature gas can be removed by the solid particle separation mechanism 2, thereby preventing solid particles from entering the heating tank 12 and accumulating inside, thus increasing the service life of the device. The solid particles separated by the solid particle separation mechanism 2 can be discharged from the device by the collection mechanism 3 to prevent them from accumulating inside the device and affecting gas flow.

[0042] Example 2

[0043] The difference from Embodiment 1 is that this embodiment discloses a liquid separation mechanism 4.

[0044] Preferably, the liquid separation mechanism 4 includes a support base 41, which is located on the left side of the solid separation box 21. A liquid collection box 42 is fixedly connected to the top of the support base 41. The bottom of the liquid collection box 42 slopes downward from back to front. A drain port 48 is fixedly connected to the bottom front of the liquid collection box 42.

[0045] A liquid removal tank 43 is inserted into the top of the support base 41. A support 44 is inserted into the bottom of the inner wall of the liquid collection tank 42. The support 44 is inserted into the inside of the liquid removal tank 43. An umbrella plate 45 is fixedly connected to the top of the support 44. A guide plate 46 is fixedly connected to the side of the support 44. A connecting pipe 47 is fixedly connected to the top of the liquid removal tank 43. A mixed gas inlet 49 is fixedly connected to the front of the liquid removal tank 43. The mixed gas inlet 49 penetrates the side of the liquid removal tank 43 and extends into the inside of the liquid removal tank 43. The mixed gas inlet 49 is located on the front of the guide plate 46.

[0046] In this embodiment, as Figure 2-4 As shown, by injecting high-temperature mixed gas into the device through the mixed gas inlet 49, the gas will condense when it comes into contact with the guide plate 46 and the umbrella plate 45. The condensed liquid droplets will drip into the liquid collection tank 42 and be discharged through the drain port 48. The separated gas is transferred to the next process through the connecting pipe 47, thereby preventing water droplets in the gas from entering the heating tank 12 and corroding it.

[0047] Example 3

[0048] The difference from Embodiment 2 is that this embodiment discloses a particle separation mechanism 2 and a collection mechanism 3.

[0049] Preferably, the solid particle separation mechanism 2 includes a connecting pipe 26, which is fixedly connected to the left side of the gas inlet 17. A solid separation box 21 is fixedly connected to the left side of the connecting pipe 26. The connecting pipe 26 extends through the side plate of the solid separation box 21 and into the interior of the solid separation box 21. A sealing door 22 is hinged to the front of the solid separation box 21. A through hole is opened on the bottom left side of the inner wall of the solid separation box 21. A filter screen 23 is inserted into the interior of the solid separation box 21. The filter screen 23 is inclined downward from right to left. A bracket 24 is provided on the right side of the filter screen 23. The bracket 24 is fixedly connected to the bottom of the inner wall of the solid separation box 21. A dust adsorption plate 25 is inserted into the interior of the bracket 24. An air inlet pipe 27 is fixedly connected to the top of the solid separation box 21.

[0050] The collection mechanism 3 includes a baffle 31, which is inserted into the through hole of the solid separation box 21. A collection box 32 is provided at the bottom of the baffle 31 and is inserted into the bottom of the solid separation box 21.

[0051] A connecting flange 51 is fixedly connected to the connection between connecting pipe 27 and air inlet pipe 27, and connecting pipe 126 is fixedly connected to gas inlet 17 through connecting flange 51.

[0052] In this embodiment, as Figure 4 and 5As shown, the separated gas is introduced into the solid separation box 21 through the inlet pipe 27, and then large particles are filtered out through the filter screen 23, and small particles are filtered out through the dust adsorption plate 25. The particles filtered out by the baffle 31 slide down to the left side of the filter screen 23 due to its inclination. By pulling out the baffle 31, the particles will fall into the collection box 32 due to gravity and then be discharged. The purified high-temperature gas enters the heating tank 12 through the gas inlet 17. The material that needs to be pretreated is injected into the pretreatment tank 14 through the feed port 15. The liquid in the pretreatment tank 14 is indirectly heated by the liquid in the heat conduction tank 13, so that the heating is more uniform and local overheating is prevented. The connection is separated by the connecting flange 51. Then, the water removal or solid impurity removal can be flexibly adjusted according to the content of liquid and solid impurities in the mixed gas.

[0053] The working principle of this utility model is as follows.

[0054] High-temperature mixed gas is injected into the device through the mixed gas inlet 49. Upon contact with the guide plate 46 and umbrella plate 45, the gas condenses, and the condensed droplets drip into the liquid collection tank 42 and are discharged through the drain port 48. The separated gas is then transferred to the next process via connecting pipe 47, preventing water droplets in the gas from entering the heating tank 12 and causing corrosion. The separated gas is then introduced into the solid separation tank 21 through the inlet pipe 27, where large particles are filtered out by filter screen 23, and small particles are filtered out by dust adsorption plate 25. Particles filtered by baffle 31 pass through the inclined surface of filter screen 23. The particles slide obliquely to the left side of the filter screen 23. By pulling out the baffle 31, the particles will fall into the collection box 32 due to gravity, and then be discharged. The purified high-temperature gas enters the heating tank 12 through the gas inlet 17. The material that needs to be pretreated is injected into the pretreatment tank 14 through the feed inlet 15. Then, the liquid in the pretreatment tank 14 is indirectly heated by heating the liquid in the heat conduction tank 13, so that the heating is more uniform and local overheating is prevented. The connection is separated by the connecting flange 51. Then, the water removal or solid impurity removal can be flexibly adjusted according to the content of liquid and solid impurities in the mixed gas.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
