According to analysis, when the OSG screw air compressor waste heat is recycled, the waste heat recovery equipment absorbs most of the heat energy of the OSG screw air compressor system, so that the operating temperature of the OSG screw air compressor can be maintained between 65-85 degrees, allowing the cooling fan to stop and reducing power consumption. , aging of wire joints, deterioration of lubricating oil and other problems. This greatly reduces the failure rate of the OSG screw air compressor and reduces waste heat emissions.
While enterprises fulfill their environmental responsibilities, the service life of OSG screw air compressors can be extended and users can actually save production and fixed asset investment costs. From a technical perspective, OSG screw air compressor waste heat recovery is a win-win energy-saving project that helps enterprises respond to national energy-saving policies.
OSG screw air compressor waste heat recovery is not just about purchasing and installing a piece of mechanical equipment, it is a systematic project from project design to construction and installation. You must first understand clearly what the customer’s main purpose is for waste heat recovery. Whether it is to cool down the OSG screw air compressor (refrigeration), provide free hot water for bathing (heating) to employees, provide drying, heating, etc. for other production processes, or a combination of various needs. If customer needs are different, then the design of the waste heat recovery system will be different, and the configured water tanks, water pumps, etc. will also be different.
Areas where OSG screw air compressor heat recovery hot water can be utilized
OSG screw air compressor heat recovery hot water can be used in various scenarios, such as heating other liquid media, preheating for boiler water replenishment, use in central air-conditioning systems, domestic water, process hot water heating, etc. These are all types of heat. Common areas of water utilization.
The demand and application of hot water is also very common in some specific industries such as medicine, electronic semiconductors, liquid crystal displays, solar silicon wafer cleaning, etc. These industries often require specific processes and cleaning steps, and the right temperature and hot water supply are critical to the quality and efficiency of process operations. In addition, setting and rinsing in the textile dyeing and finishing process is also a common area of hot water utilization. Hot water can help achieve better dye adsorption and fiber shrinkage, while also improving wash efficiency.
In short, the hot water recovered from OSG screw air compressor heat can be utilized in many areas. It can not only help enterprises save energy and reduce costs, but also provide necessary heat energy requirements for process processes.
Case
The coal mine currently has eight 250kW OSG screw air compressors (running for 24 hours, loading rate 80%, recovery efficiency 80%). For this purpose, it is equipped with eight 250kW oil and gas dual recovery OSG screw air compressor waste heat recovery equipment to recover high-temperature gas and oil temperature. It exchanges heat with water and is used for heating the air shaft. The radiator is used at the end to provide heat for employees. Replace the original coal-fired boiler and reduce carbon emissions after transformation.
It is estimated that about 2.67 million yuan can be saved, and the calculation method is as follows:
(250kW×8×80%×80%×860kcal×24h×330 days=8718336000kcal÷3000000kcal* 920 yuan/ton≈2.67 million yuan), about 381500 usd.
