Description

Technical Field

[0001] This utility model relates to the technical field of raw material pre-melting device for drying room using waste heat of air compressor, specifically a raw material pre-melting device for drying room using waste heat of air compressor. Background Technology

[0002] In industrial production, the pre-melting of raw materials in drying ovens requires a continuous and stable heat source. Traditional methods often rely on boiler rooms for power supply or electric heating, which not only consumes large amounts of fossil fuels or electricity, leading to high energy costs, but also generates additional carbon emissions due to low energy conversion efficiency. Meanwhile, air compressors widely used in industrial settings generate significant waste heat during operation. This waste heat is often directly discharged into the environment through exhaust, resulting in energy waste and potentially affecting the stability of air compressor operation due to insufficient heat dissipation, creating an energy supply-demand mismatch where the drying oven requires heat while the air compressor releases heat.

[0003] Existing waste heat recovery devices have significant limitations: First, they are limited to a single form of waste heat recovery, mostly targeting only hot water or hot air, and cannot simultaneously meet the hot air demand of the drying room and the hot water demand of the boiler room and tank area. Second, the heat transfer path is long, the heat exchange efficiency is low, and there is a lack of flexible diversion control structure, making it difficult to adjust the waste heat distribution according to actual operating conditions. Third, the equipment layout is unreasonable, and hot water storage and transportation rely on pump equipment, which increases energy consumption and further reduces the cost-effectiveness of energy utilization. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pre-melting device for drying oven raw materials that utilizes the waste heat of an air compressor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pre-melting device for raw materials in a drying room that utilizes the waste heat of an air compressor, comprising: a platform, a hot water storage tank, a heat exchanger, an air compressor, a boiler room soft water storage tank, a heated hot water tank, soft water pipes, hot water pipes, and valves.

[0006] The hot water storage tank is connected to an external soft water supply via a soft water pipe, and a valve is installed on the soft water pipe. The hot water storage tank is connected to the boiler room soft water storage tank and the heat tracing hot water tank via hot water pipes, and valves are installed on the hot water pipes.

[0007] As a further description of the above technical solution: The hot water storage tank is fixedly arranged above the platform, and a heat exchanger is arranged below the platform.

[0008] As a further description of the above technical solution: The air compressor has a tee at the exhaust end. One end of the tee is connected to an exhaust switch via a pipe, and the other end of the tee is equipped with an airflow fan. The pipe on the airflow fan is connected to the drying room.

[0009] As a further description of the above technical solution: The heat exchanger is connected to the air compressor via a pipeline, and the outlet of the heat exchanger is connected to the hot water storage tank via a hot water pipe.

[0010] As a further description of the above technical solution: A hot water controller is fixedly arranged on one side of the hot water tank to control the temperature and flow rate of the hot water in the heat tracing system.

[0011] As a further description of the above technical solution: The hot water tracing tank has a capacity of 0.5t, and the boiler room soft water storage tank has a capacity of 2t. As a further description of the above technical solution: The hot water storage tank is 1.7m. 3 The resin storage tank, the soft water pipe is made of PPR pipe, the air compressor is a 90kw air compressor, and the valve is a stainless steel float valve.

[0012] This utility model has the following beneficial effects: 1. By setting up the exhaust tee and airflow fan of the air compressor, the waste heat of the air compressor is precisely directed to the drying room in the form of hot air, which can be used to replenish water for the boiler room and provide heat tracing for the tank area. This enables the cascade utilization of waste heat, hot air and hot water, which greatly improves energy efficiency and reduces production energy costs.

[0013] 2. By leveraging the platform to create a height difference between the hot water storage tank and other storage tanks, and coordinating with valve control, hot water can flow by gravity, reducing the investment in pump equipment and energy consumption; the heat exchanger is connected to the air compressor nearby, shortening the heat transfer path and enhancing the efficiency of waste heat recovery.
