Intelligent modularized boiler flue gas waste heat energy water heating device

Abstract

The invention provides an intelligent modularized boiler flue gas waste heat energy water heating device. The device mainly comprises an intelligent controller, a tubular heat exchanger, a superconducting heat pipe heat exchanger, a clean water flow pipeline and a high-temperature flue gas passage. Both the tubular heat exchanger and the superconducting heat pipe heat exchanger are formed by combining a plurality of single modules with the same structure and the uniform specification. The clean water flow pipeline is arranged in each module by section, and the clean water flow pipeline and the high-temperature flue gas passage respectively form a main pipeline and a main passage which are communicated by combination of the modules. Because of the modularized combined structure, the device is small in integral volume and fast and convenient in installation, maintenance and module replacement, and does not affect the integral operation; the number of the modules can be increased or reduced according to the actual requirement, so that the device meets the requirement for recycling the heat energy of flue gas or other waste gas of boilers of different tonnage, and has strong adaptability and universality and high heat efficiency; and the device can realize automatic operation and safety monitoring in the whole process.

Description

technical field [0001] The invention relates to energy saving and emission reduction and waste heat energy reuse technology, in particular to the waste heat energy reuse technology of boiler flue gas, in particular to an intelligent modular boiler flue gas waste heat energy water heating device. Background technique [0002] Boilers are commonly used equipment in industrial production. According to monitoring statistics, the operating efficiency of industrial boilers in my country is generally low, generally only reaching 85-90% of the original design index. The main reason is that the amount of smoke exhausted by boiler combustion is large and the temperature is high (180-220C°); the second is that the carbon content of the unburned ash is too high. In order to improve the operating efficiency of boilers, relevant scientific and technical personnel have carried out a number of researches. But for a long time, the status quo of large boiler flue gas discharge and high temp...
