TECHNICAL FIELD
[0001] The utility model relates to energy recycling technical field, concretely is heat energy recycling drying system. BACKGROUND
[0002] In the steel wire manufacturing industry, the fine specification product with diameter 0 and 1.5mm needs to pass through hot lime soaking treatment and subsequent drying process, but such traditional process has energy waste problem. For example, in the production site of the applicant, the bottom of lime pool is heated by natural gas combustion, and the high-temperature flue gas (600-800 DEG C) is directly discharged, and the heat loss can reach more than 85%, at the same time, the drying process needs to burn natural gas additionally, and the comprehensive energy consumption of unit product reaches 12.7MJ / kg. SUMMARY
[0003] The utility model provides heat energy recycling drying system can solve the technical problem of high heat energy consumption in the soaking and drying two processes of product.
[0004] The application provides the following technical scheme:
[0005] The heat energy recycling drying system comprises a soaking pool for soaking products, a heating component for heating the soaking pool, a recess is formed on the ground as a mounting groove for the heating component, a drying component comprising an oven, a hollow support for placing products is arranged in the oven, the mounting groove is connected with the bottom pipeline of the oven, and a through hole is formed on the top of the oven as an exhaust port.
[0006] Beneficial effects:
[0007] 1. Improve energy utilization rate: the mounting groove where the heating component is located is connected with the pipeline of the oven, and the residual heat of the heating component is used for drying process, which significantly improves the energy utilization rate. The high-temperature flue gas generated by heating the soaking pool is recovered, and the residual heat is transmitted to the oven, realizing the drying treatment of steel wire products. This design not only reduces the heat loss of direct discharge, but also avoids the need for additional natural gas combustion for drying, greatly reduces the comprehensive energy consumption of unit product, and realizes significant energy-saving effect.
[0008] 2. Provide a relatively sealed heat energy gathering environment: the mounting groove not only provides an installation environment for the heating component for heating the soaking pool, but also forms a relatively sealed heat energy gathering environment under the covering of the bottom panel of the soaking pool. This design effectively reduces heat loss and enhances heat energy gathering effect. The setting of oxygen pipeline further optimizes the combustion condition, ensures sufficient combustion of fuel, and improves thermal efficiency. At the same time, the sealed environment helps to maintain a higher temperature, so that more heat can be transferred to the oven, further improving the drying effect and energy utilization rate.
[0009] 3. Accelerate heat energy transfer: The installation of oxygen pipelines not only creates the necessary conditions for combustion heating but also accelerates the transfer of heat energy. Adequate oxygen supply ensures a more complete and efficient combustion process, and the high-temperature flue gas generated can quickly transfer to the oven, rapidly and uniformly drying the steel wire products placed on the hollow support.
[0010] Further, as an improvement, an acceleration flow guide component is arranged in the pipeline to enhance the flow of heat energy.
[0011] Beneficial effects: This design significantly improves the flow speed and transfer efficiency of heat energy in the pipeline. The acceleration flow guide component optimizes the fluid dynamics inside the pipeline, reducing heat loss during transmission, ensuring that more heat can be quickly and uniformly transferred to the oven. This improvement not only improves the efficiency of heat energy utilization but also shortens the drying time, improving overall production efficiency.
[0012] Further, as an improvement, a sliding block is arranged on the top of the hollow support.
[0013] Beneficial effects: When placing steel wire on the hollow support in the oven, the sliding block is pulled out, the steel wire is placed on the sliding block, and then the sliding block is pushed back into the oven to perform the drying step. The setting of the sliding block saves the labor needed to adjust the position of the steel wire.
[0014] Further, as an improvement, the acceleration flow guide component is a spiral flow guide fixed on the inner wall of the pipeline.
[0015] Beneficial effects: The design of the spiral flow guide significantly improves the heat transfer efficiency and fluid flow stability in the heat transfer pipeline. By arranging spiral flow guides on the inner wall of the pipeline, the hot air flow can be guided to flow along a spiral path, increasing the contact area between hot air and the inner wall of the pipeline, thereby improving heat conduction efficiency.
[0016] Further, as an improvement, the acceleration flow guide component is a tapered section fixed in the middle section of the pipeline.
[0017] Beneficial effects: The design of the tapered section significantly improves the transmission speed and efficiency of the hot air flow in the pipeline. By arranging a tapered section in the middle section of the pipeline, the Bernoulli principle can be used to accelerate the airflow when passing through the tapered section, thereby increasing the transmission speed and kinetic energy of the hot air flow. This design not only enhances the transfer efficiency of heat energy but also enables heat to reach the target area in a shorter time, accelerating the drying speed of the product.
[0018] Further, as an improvement, the outlet of the pipeline in the oven is horizontally oriented towards the side wall of the oven.
[0019] Beneficial effects: By setting the pipeline outlet horizontally towards the side wall of the oven, the high-temperature gas entering the oven can flow along the side wall, forming a uniform air circulation. This layout avoids the direct impact of hot air on the product, reducing the problem of uneven product quality caused by local overheating. At the same time, it also prevents water droplets on the product from falling into the pipeline. BRIEF DESCRIPTION OF DRAWINGS

In the embodiment, the heating component 200 mainly comprises a gas pipeline 202, a burner 203, an oxygen pipeline 204 and an igniter, wherein the burner 203 is arranged in the installation groove 201 corresponding to the center of the bottom of the soaking pool 100, the gas pipeline 202 is responsible for conveying natural gas to the burner 203, the oxygen pipeline 204 is responsible for conveying oxygen to the installation groove 201, and the igniter is installed on the side of the burner 203 at a distance of 100mm from the flame outlet. The igniter is made of high-temperature resistant ceramic material to ensure its long-term stable operation. The specific structure of the heating component 200 is not described here, which mainly heats the soaking pool 100 by generating a flame.
