Description

Technical Field

[0001] This utility model relates to the field of energy reuse technology, specifically to a device for recovering waste heat from incinerators. Background Technology

[0002] Waste heat recovery devices for incinerators are used to recover excess heat generated during the operation of incinerators. Their core function is to improve energy efficiency, reduce energy costs, and reduce environmental pollution. During the process of treating waste or burning fuel, incinerators produce a large amount of high-temperature flue gas, which carries a large amount of heat energy. Waste heat recovery devices use heat exchange technology to recover this heat energy and convert it into usable energy forms such as steam, hot water, or electricity, thereby significantly improving the energy efficiency of the entire system.

[0003] According to a patent published on the China Patent Network, the patent title is: "A Waste Heat Recovery Device for an Incinerator," patent application number: 202321810037.1. This utility model discloses a waste heat recovery device for an incinerator, including a furnace shell. Inside the furnace shell, from front to back, are sequentially installed a secondary waste gas preheater, a thermal oil heat exchanger, a primary waste gas preheater, a fresh air preheater, and a hot water heat exchanger. An induced draft fan is installed at the rear end of the top of the furnace shell. One side of the furnace shell... A fan support frame is installed at the front end, and an exhaust gas fan is mounted on top of the fan support frame. This invention utilizes a primary exhaust gas preheater before the exhaust gas enters a secondary exhaust gas preheater. The temperature of the exhaust gas entering the furnace is controlled by a proportional valve and a high-temperature heat bypass valve. The exhaust gas preheating temperature is generally set at around 620℃ to avoid excessively high preheating temperatures that could cause the exhaust gas to burn in the heat exchange tubes and damage them, or excessively low preheating temperatures that could result in incomplete combustion and non-compliance with emission standards. However, the exposed transmission pipes of this waste heat recovery device pose a safety hazard as their high surface temperatures could potentially injure workers.

[0004] Therefore, it is necessary to redesign and modify the waste heat recovery device to effectively prevent the lack of protective measures and potential safety hazards. Utility Model Content
