Description

Technical Field

[0001] The utility model belongs to the field of gas boilers, in particular to a condensing energy-saving device for gas boilers. Background Art

[0002] The gas boiler condensing energy-saving device is an advanced energy utilization equipment. Before the flue gas is condensed, the flue gas will be filtered first. Through filtering, impurities and particulate matter in the flue gas can be removed, and then relatively pure water vapor is allowed to enter the condenser. In the condenser, the water vapor is cooled to form liquid, realizing energy recovery and utilization, which significantly reduces energy waste. However, at present, this type of device has the disadvantage of being inconvenient to disassemble and assemble in actual applications. The inconvenient disassembly and replacement of the filter components is a prominent problem. Due to the unreasonable design structure of the device and the lack of a convenient disassembly and assembly mechanism, when the filter components need to be replaced or cleaned, the operation is very cumbersome, which consumes a lot of time and manpower. The filtering effect of the filter components that have not been replaced for a long time will gradually decrease, and it will not be able to effectively remove impurities in the flue gas, which will affect the subsequent condensation process and energy recovery effect. In order to solve this problem, it is necessary to develop a gas boiler condensing energy-saving device. Utility Model Content
