AI Technical Summary

Technical Problem

There is a problem of insufficient heat exchange during the heat exchange process of existing boilers, especially the waste of heat energy caused by vertical heat exchange method and the asymmetric heat exchange between low-temperature water and high-temperature flue gas.

Method used

The cyclone heat exchange method is adopted, and heat exchange is exchanged by setting high-temperature water and high-temperature flue gas, and heat exchanged with low-temperature flue gas. The heat exchange water is used to absorb heat in the gaps of the flue gas pipelines, and transport it to the heat exchange box for heating through the high-temperature pipeline to achieve full utilization of heat.

Benefits of technology

The adequacy of heat exchange is achieved, heat energy waste is avoided, the efficiency and energy saving effect of the boiler is improved, and the operation is simplified and the cost of energy conversion is reduced.

Abstract

The utility model relates to the technical field of boilers, and discloses an efficient energy-saving boiler which comprises a boiler assembly, a conveying assembly and a heat exchange assembly, the boiler assembly comprises a boiler body, a combustion chamber, a heat exchange chamber and a conveying chamber, the combustion chamber, the heat exchange chamber and the conveying chamber are arranged in the boiler body, and a plurality of smoke pipelines are arranged in the heat exchange chamber; the conveying assembly comprises a feeding hopper, a discharging hopper and a conveying belt which are installed on the furnace body, and the feeding hopper and the discharging hopper are connected with the conveying belt end to end. According to the efficient energy-saving boiler, by arranging the partition plate, the flowing direction of heat exchange water can be guided, the flowing direction of the heat exchange water is opposite to the exhaust direction of flue gas, when the heat of the flue gas is absorbed, the heat in the flue gas can be fully absorbed through the heat exchange water, and heat exchange is conducted through high-temperature water and high-temperature flue gas; the low-temperature water exchanges heat with the low-temperature flue gas, meanwhile, the heat exchange mode is cyclone heat exchange, heat exchange can be fully carried out, and then the problem of insufficient heat exchange is avoided.
