Description

Technical Field

[0001] This utility model relates to the field of dechlorination oven technology, specifically a high-temperature dechlorination oven. Background Technology

[0002] In scenarios requiring high-temperature dechlorination, such as the purification of chemical intermediates, the recycling of chlorinated plastics, and the removal of chlorine residues from metal surfaces, traditional dechlorination ovens typically use heating tubes to directly heat the internal space of the oven to promote the volatilization and release of chlorine from the materials. However, such equipment has significant drawbacks in heat utilization: the heat generated by the heating tubes is only transferred to the materials through radiation and natural convection, and a large amount of heat is lost due to heat dissipation and exhaust processes. At the same time, in order to maintain the high-temperature environment inside the oven, energy needs to be continuously consumed for heating. Especially when the batch size is large or the dechlorination temperature requirement is high, the problem of energy waste is prominent, resulting in high energy consumption and high processing costs in the dechlorination process. Existing technologies cannot achieve heat recycling and are difficult to adapt to the energy-saving and environmental protection requirements of high-energy-consumption scenarios. Therefore, we need to provide a high-temperature dechlorination oven. Utility Model Content

[0003] The purpose of this utility model is to provide a high-temperature dechlorination oven, which is equipped with heating tubes inside the oven to heat the interior, and is also equipped with an air supply component that can utilize the residual heat of the heating tubes to heat the outside air before supplying it into the oven, thereby realizing the utilization of the heat source and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature dechlorination oven, comprising: The enclosure includes a housing, a track, a moving platform, and a heat circulation mechanism. The moving platform and track are installed inside the housing. The track is used for adjusting the movement of the moving platform. The heat circulation mechanism is installed inside the housing and is used to heat the material on top of the moving platform to achieve dechlorination. The heat circulation mechanism includes a heating box, heating pipes, and a gas supply component. The heating box is embedded in the top of the box body and has two heating pipes inside. The gas supply component is installed inside the heating box and is used to supply hot air to the box body.

[0005] Preferably, the air supply component includes an air intake fan, a heat-insulated air intake pipe, a heat-conducting pipe, and an exhaust section.

The exhaust end of the heat-insulated air intake pipe is equipped with a heat-conducting pipe, and both exhaust ends of the heat-conducting pipe are equipped with exhaust sections.

[0015] 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.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a high-temperature dechlorination drying oven, comprising: Box 1, track 2, moving platform 3, and heat circulation mechanism 4. The moving platform 3 and track 2 are installed inside the box 1. The track 2 is used for the movement adjustment of the moving platform 3. The heat circulation mechanism 4 is installed inside the box 1 and is used to heat the material on the top of the moving platform 3 to achieve dechlorination. The heat circulation mechanism 4 includes a heating box 41, heating pipes 42 and air supply component 43. The heating box 41 is embedded in the top of the box 1. Two heating pipes 42 are provided in the heating box 41. The air supply component 43 is installed in the heating box 41 and is used to supply hot air to the box 1. Specifically, a heating tube 42 is installed inside the heating chamber 41 to heat the interior of the chamber 1, and an air supply component 43 is provided to utilize the waste heat of the heating tube 42 to heat the outside air before it is introduced into the chamber 1, thus realizing the utilization of the heat source. By recovering the waste heat of the heating tube 42 through the air supply component 43, the outside air is preheated in the heating chamber 41 before being sent into the chamber 1, avoiding the problem of direct heat loss from the heating tube 42 in traditional equipment. When the preheated air enters the chamber 1, the temperature difference is small, which can reduce the temperature fluctuation inside the chamber, making the material more evenly heated, the dechlorination reaction more stable, and reducing the risk of material deterioration caused by local overheating. In addition, the utilization of waste heat reduces the continuous workload of the heating tube 42, which not only extends the service life of the heating tube 42, but also reduces the overall energy consumption of the equipment.

[0017] The air supply component 43 includes an air intake fan 431, a heat-insulated air intake pipe 432, a heat-conducting pipe 433, and an exhaust section 434. The heat-insulated air intake pipe 432 is embedded in one side of the heating box 41, and the air intake end is equipped with an air intake fan 431. The exhaust end of the heat-insulated air intake pipe 432 is equipped with a heat-conducting pipe 433, and both exhaust ends of the heat-conducting pipe 433 are equipped with exhaust sections 434. Furthermore, the heat-insulating air inlet pipe 432 is made of aluminum silicate fiber. One end of it is embedded and fixed in the reserved installation hole on the side wall of the heating box 41 and communicates with the inside of the heating box 41. The other end extends to the outside of the heating box 41 and is sealed to the air outlet of the air intake fan 431 through a flange. The end of the heat-insulating air inlet pipe 432 located inside the heating box 41 is welded to the air inlet end of the heat-conducting pipe 433. The heat-conducting pipe 433 is made of 310S high-temperature resistant stainless steel. Its two exhaust ends are respectively connected to two exhaust parts 434 through threaded sealing. The heat-insulating air inlet pipe 432 can prevent the heat inside the heating box 41 from being lost to the outside through the pipe, ensuring the heating efficiency of the outside air. The 310S stainless steel heat-conducting pipe 433 can withstand high temperatures above 800℃ and has good thermal conductivity, which can efficiently absorb the waste heat of the heating pipe 42.

[0018] The heat pipe 433 is installed in a serpentine shape inside the housing 1 and is located at the bottom of the two heating pipes 42; It is worth noting that the heat pipe 433 is distributed in a serpentine, meandering manner inside the housing 1, and its entire structure is located 3-5 cm directly below the two heating pipes 42. The serpentine structure extends the airflow path in the heating chamber 41, which can more fully absorb the residual heat of the heating pipes 42 and increase the air heating temperature. At the same time, the position located directly below the heating pipes 42 can maximize the utilization of the radiant heat of the heating pipes 42, solve the problem of insufficient heating of traditional straight-pipe air supply pipes, and improve the air preheating effect.

[0019] The exhaust section 434 includes an exhaust pipe 4341 and an air frame 4342. The air inlet of the exhaust pipe 4341 is connected to the exhaust outlet of the heat pipe 433. The exhaust outlet of the exhaust pipe 4341 is provided with multiple air frames 4342. It should be noted that the exhaust pipe 4341 is made of the same 310S high-temperature resistant stainless steel as the heat pipe 433. Its air inlet end is sealed to the exhaust end of the heat pipe 433, and its exhaust end is welded to the air inlet of the air frame 4342. The air frame 4342 is a rectangular frame structure made of aluminum alloy. The exhaust pipe 4341 and the heat pipe 433 are made of the same material, which ensures the connection stability in high-temperature environments. The air frame 4342 blows the hot air flow toward the material, which solves the problem of local overheating of the material caused by the concentrated airflow of the traditional exhaust port, making the material more evenly heated and the dechlorination reaction more stable.

[0020] The top of the mobile platform 3 is equipped with a perforated ceramic frame 5 via a mounting bracket, and the perforated ceramic frame 5 is a modified ceramic frame; Furthermore, the porous ceramic frame 5 is made of cordierite, and its surface is loaded with active ingredients of calcium oxide and magnesium oxide through an impregnation method. The modified porous ceramic frame 5 utilizes the chemical adsorption of calcium oxide and magnesium oxide with chlorine-containing gas to enhance the chlorine capture capacity.

[0021] Multiple auxiliary seats 6 are installed on both sides of the top of the mobile platform 3. The auxiliary seats 6 are located in the air frame 4342 and the air outlet direction is set in an arc shape. A main seat 7 with arc surfaces on both sides is provided at the center of the top of the mobile platform 3. Both the auxiliary seat 6 and the main seat 7 are made of ceramic fiber reinforced composite material. The auxiliary seat 6 is symmetrically installed on both sides of the top of the moving platform 3 by bolts, and the main seat 7 is fixed to the center of the top of the moving platform 3 by welding. The ceramic fiber reinforced composite material has good high temperature resistance and heat insulation, which prevents the seat from deforming at high temperatures. The arc-shaped surface of the auxiliary seat 6 can guide the hot air blown out by the air frame 4342 upward, while the arc-shaped surface of the main seat 7 plays a converging role for the hot air, so that the hot air flows more concentratedly to the material on the porous ceramic frame 5, which solves the problem of uneven distribution of hot air and improves the heating efficiency of the material.

[0022] The bottom of the heating box 41 is embedded with a heat-conducting plate 8, and the surface of the box body 1 is equipped with a high-temperature resistant circulating gas pipe. The heat-conducting plate 8 at the bottom of the heating box 41 is made of aluminum nitride ceramic material with a thickness of 3-5mm. It is fixed to the opening at the bottom of the heating box 41 by high-temperature resistant adhesive. The high-temperature resistant circulating gas pipe on the surface of the box 1 adopts a double-wall corrugated pipe structure and is made of Inconel 600 alloy. One end of the pipe is connected to the inside of the box 1, and the other end is connected to the external purification device. The pipe is equipped with a flow control valve. The aluminum nitride ceramic heat-conducting plate 8 has a high thermal conductivity, which can quickly transfer the heat in the heating box 41 to the box 1, thereby improving the heating efficiency. The circulating gas pipe with double-wall corrugated pipe structure has good flexibility and high temperature resistance, which is convenient for installation and adapts to the thermal expansion and contraction of the box 1. The flow control valve can adjust the exhaust volume to keep the gas pressure in the box 1 stable, which solves the problem of poor exhaust or unstable gas pressure affecting the dechlorination effect of traditional equipment.

[0023] The track component 2 includes a high-temperature resistant wheel set 21 and a guide rail 22. The bottom of the moving platform 3 is provided with two high-temperature resistant wheel sets 21, and the bottom of the inner wall of the box 1 is provided with a guide rail 22 for guiding the movement of the high-temperature resistant wheel sets 21.

[0024] The 42 heating elements and 431 air intake fan involved in this application are all implemented using existing mature technologies and are connected to an external PLC controller and power supply. This is a conventional technical means in this field, so the specific circuit connection, control logic and working process will not be described in detail.

[0025] Both the housing 1 and the heating chamber 41 of this device are insulated boxes, and the intake fan is a high-temperature resistant fan. The heating pipe 42 is activated to heat the interior of the heating chamber 41. A heat-conducting plate 8 is located at the bottom of the heating chamber 41 to transfer heat to the interior of the housing 1. The intake fan is activated, and a filter screen is installed at the intake of the fan to intercept impurities. Air enters the heat-conducting pipe 433 through the insulated intake pipe 432. The heat-conducting pipe 433 is distributed in a serpentine pattern within the heating chamber 41, extending the airflow path and allowing for better heating of the air. The hot air is discharged from the air frame 4342 through the exhaust pipe 4341, and the air frame 4342 blows the hot air towards the auxiliary seat 6 and... The main seat 7, and the auxiliary seat 6, have an arc-shaped surface on the side near the air frame 4342, which can guide hot air upward to the dechlorinated object. The object is placed on the porous ceramic frame 5. Since the porous ceramic frame 5 has undergone surface modification, it enhances the capture ability of chlorine-containing gas through chemical adsorption, which significantly improves the dechlorination effect. The bottom of the moving platform 3 is equipped with a high-temperature resistant wheel set 21, which moves within the guide rail 22 and plays a role in positioning and installing the moving platform 3. At the same time, the surface of the box 1 is equipped with a high-temperature resistant circulating air pipe, which can exhaust the air inside the box 1. The exhaust air needs to be purified.
