Description

Technical Field

[0001] This utility model relates to the field of carbonization furnace technology, specifically to a tar protection device that combines a thermal barrier and condensation collection for a carbonization furnace. Background Technology

[0002] During the continuous and stable operation of the carbonization furnace, the raw materials are placed in a high-temperature environment. This extreme condition induces a series of complex and intertwined physical and chemical changes within the raw materials. A large amount of tar is generated during these complex physical and chemical changes. After being generated, the tar rises with the continuously flowing airflow within the furnace. However, the airflow and temperature distribution inside the carbonization furnace are not uniform. Due to the combined influence of various factors such as the furnace's structural characteristics, the arrangement of heating elements, and the distribution of the raw materials within the furnace, there are significant differences in airflow velocity and temperature at different locations within the furnace. This uneven distribution of airflow and temperature causes the tar to lose its stable movement during its ascent. When the tar drips onto the battery felt, it quickly penetrates the fiber structure of the battery felt, altering its physical and chemical properties. For example, the tar may clog the pores of the battery felt, affecting its permeability; some components of the tar may also react chemically with the battery felt material, leading to a decrease in the battery felt's strength and a deterioration in its insulation performance.

[0003] Severely affecting the performance of battery felt directly impacts the quality of subsequent products. Current technology has yet to provide a comprehensive and effective solution. Therefore, developing a highly efficient tar protection system is of significant practical importance. It can not only improve product quality and reduce production costs and risks for enterprises, but also promote the further development of carbonization furnace production technology.

[0004] In view of this, we propose a tar protection device that combines a thermal barrier and condensation collection for a carbonization furnace. Utility Model Content

[0005] The purpose of this invention is to provide a tar protection device that combines a thermal barrier and condensation collection for a carbonization furnace, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tar protection device combining a thermal barrier and condensation collection for a carbonization furnace includes a carbonization furnace body. A thermal barrier assembly is installed inside the furnace body, positioned above a battery felt. Condensation collection assemblies are symmetrically arranged on both sides of the furnace body. Each condensation collection assembly includes a condenser pipe, a collection tank, and a circulating cooling system. The condenser pipe is fixedly installed on both sides of the furnace body, the collection tank is located below the condenser pipe, and the circulating cooling system is located outside the furnace body and connected to the condenser pipe.

[0008] Preferably, the heat barrier assembly is made of a high-temperature resistant heat insulation material, and the heat barrier assembly is corrugated.

[0009] Preferably, the inner wall of the carbonization furnace is symmetrically provided with slots, and the two sides of the heat barrier component are provided with blocks, which are engaged in the slots.

[0011] Preferably, the distance between the thermal barrier assembly and the battery felt is 15cm to 25cm.

[0012] Preferably, the condenser tubes are fixedly installed in a serpentine shape on both sides inside the carbonization furnace body.

[0013] Preferably, the condenser tubes are spirally fixed on both sides inside the carbonization furnace body.

[0014] Preferably, the circulating cooling system is a circulating water cooling system or a liquid nitrogen cooling system consisting of a cooling tower and a circulating water pump.

[0015] Preferably, the thermal barrier assembly is inclined downwards at both ends.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The tar protection device of this carbonization furnace, combining a thermal barrier and a condensation collection system, utilizes the thermal barrier component to initially reduce the risk of tar contamination of the battery felt by blocking hot airflow and condensing some of the tar. The condensation collection component then effectively collects the remaining tar, further enhancing the protective effect. The synergistic effect of both components reduces the likelihood of tar dripping onto the battery felt from multiple perspectives, effectively ensuring the quality of the battery felt and consequently guaranteeing the performance and stability of subsequent products. This provides strong support for the efficient and stable production of the carbonization furnace. Attached Figure Description

[0025] Example 1

[0026] Please see Figures 1-2 As shown, this utility model provides a technical solution:

[0027] A tar protection device combining a thermal barrier and condensation collection for a carbonization furnace includes a carbonization furnace body 5. A thermal barrier assembly 1 is installed inside the carbonization furnace body 5 and is positioned above a battery felt. Condensation collection assemblies are symmetrically arranged on both sides inside the carbonization furnace body 5. Each condensation collection assembly includes a condensation pipe 2, a collection tank 3, and a circulating cooling system 4. The condensation pipe 2 is fixedly installed on both sides inside the carbonization furnace body 5. The collection tank 3 is located below the condensation pipe 2. The circulating cooling system 4 is located outside the carbonization furnace body 5 and is connected to the condensation pipe 2.

[0028] Furthermore, the thermal barrier component 1 is made of a high-temperature resistant thermal insulation material, which is a ceramic fiber felt or a novel high-temperature resistant composite thermal insulation material.

[0029] In this embodiment, aluminum silicate fiber felt is selected as the high-temperature resistant insulation material for the thermal barrier assembly. Aluminum silicate fiber felt has excellent high-temperature resistance and can work stably for a long time in environments up to 1200°C, while also having good thermal insulation effect.

[0030] Furthermore, the heat barrier component 1 is wavy. Compared to a planar structure, this shape increases the contact area with the rising hot airflow by approximately 35%, thereby improving the condensation effect of the rising tar on the heat barrier component 1.

[0031] In this embodiment, the inner wall of the carbonization furnace body 5 is symmetrically provided with slots 51, and the two sides of the heat barrier component 1 are provided with blocks 11. The blocks 11 are engaged in the slots 51, which facilitates the disassembly and installation of the heat barrier component 1.

[0032] Furthermore, during installation, the distance between the heat barrier assembly 1 and the battery felt is 15cm to 25cm to ensure that the heat barrier assembly 1 can effectively block the rising hot airflow. Preferably, in this embodiment, the heat barrier assembly 1 is installed approximately 20cm above the battery felt.

[0033] In this embodiment, the condenser tube 2 is fixedly arranged in a serpentine shape on both sides inside the carbonization furnace body 5. This design increases the contact area between the condenser tube 2 and the tar, allowing the tar that has not been condensed by the heat barrier component 1 to be fully condensed by the condenser tube 2 and collected in the collection tank 3.

[0034] It is worth noting that in this embodiment, the condenser tube is made of 304 stainless steel, which is not only corrosion-resistant but also has good thermal conductivity. The collection tank is made of high-temperature resistant polytetrafluoroethylene and is placed about 5cm directly below the condenser tube to collect the condensed tar liquid.

[0035] In this embodiment, the circulating cooling system 4 is a circulating water cooling system consisting of a cooling tower and a circulating water pump. The circulating water pump transports the cooling water in the cooling tower to the condenser 2 through pipelines. The water outlet of the condenser 2 returns to the cooling tower for cooling and reuse.

[0036] The circulating cooling system 4 provides cooling water at a temperature of 18°C ​​to the condenser 2. The cooling water circulates continuously within the condenser 2 under the action of the circulating water pump, carrying away the heat released during tar condensation.

[0037] During the operation of the carbonization furnace, the internal temperature reaches 1000℃-1200℃. The raw materials undergo a series of reactions at this high temperature, producing a large amount of tar, which rises with the hot airflow. The heat barrier component 1 comes into play first; its corrugated structure increases the contact area with the hot airflow, successfully blocking approximately 45% of the hot airflow. Simultaneously, the heat barrier component 1 exchanges heat with the rising hot airflow, and some of the tar rapidly condenses into liquid on its surface. The tar that is not blocked by the heat barrier component 1 continues to flow with the airflow to both sides of the furnace body, where it further condenses into liquid under the action of the condenser pipe 2 and drips into the collection tank 3 below. After a week of continuous operation and testing, technicians conducted a detailed inspection of the battery felt and found no obvious traces of tar contamination. Furthermore, performance tests were conducted on products produced using this protective device, and all indicators met quality standards. The product qualification rate increased from 80% to 95%, effectively ensuring product quality and reducing production costs.

[0038] Example 2

[0039] This embodiment is a further improvement on embodiment 1.

[0040] In this embodiment, the thermal barrier component 1 uses a novel alumina-mullite composite fiber felt as a high-temperature resistant insulation material. This composite fiber felt combines the advantages of alumina and mullite, exhibiting higher high-temperature resistance and better insulation performance, and can operate stably in high-temperature environments above 1300℃.

[0041] Furthermore, the wave shape of the heat barrier component 1 is inclined downwards at both ends. Through optimized design, the contact area with the rising hot airflow is increased by 15% compared to a normal wave-shaped structure. During installation, the heat barrier component is installed about 15cm above the battery felt to maximize its function of blocking hot airflow and condensing tar.

[0042] In the condensation collection assembly, the condenser tubes are made of 316L stainless steel, a material with superior corrosion resistance that can withstand the complex environment inside the furnace. The condenser tubes 2 are arranged in a spiral structure on both sides of the furnace body. This spiral structure increases the contact time and area between the tar and the condenser tubes 2, further improving the condensation effect. The collection tank 3 is made of high-purity quartz glass and is placed approximately 3cm below the condenser tubes. Quartz glass has excellent high-temperature resistance and corrosion resistance, ensuring that the collected tar liquid will not damage the collection tank 3. The circulating cooling system uses a liquid nitrogen cooling system, delivering liquid nitrogen to the condenser tubes through pipes to provide a cooling environment as low as -15°C. The liquid nitrogen rapidly vaporizes inside the condenser tubes 2, absorbing a large amount of heat, allowing the tar to condense quickly.

[0043] In actual operation, the temperature of the carbonization furnace is controlled between 1100℃ and 1300℃. When the hot gas stream carrying tar rises, the heat barrier component 1 blocks approximately 55% of the hot gas stream, causing a large amount of tar to condense into liquid on its surface. The spiral condenser 2 further enhances the condensation effect of the remaining tar, increasing the tar collection volume in the collection tank by approximately 40% compared to when the system was not used. After a period of operation, testing of the battery felt showed that it was not contaminated by tar. Simultaneously, performance evaluation of the produced products showed that all performance indicators met the requirements of high-end products, production efficiency increased by approximately 20%, product quality was significantly improved, and the company's competitiveness in the market was enhanced.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
