Description

Technical Field

[0001] The utility model relates to the technical field of condensing boilers, in particular to a gas condensing boiler unit. Background Art

[0002] Condensing boilers use efficient condensing waste heat recovery devices to absorb the sensible heat in the high-temperature flue gas discharged by the boiler and the latent heat released by the condensation of water vapor, so as to achieve the purpose of improving the thermal efficiency of the boiler. Fuel combustion will produce a large amount of CO2, NOX and a small amount of SO2. These substances are discharged into the atmosphere, which will cause the greenhouse effect and acid rain, and have a destructive effect on the environment. Condensing boilers can easily remove these harmful substances in the flue gas while condensing the water vapor in the flue gas.

[0003] Existing gas-fired condensing boiler units, such as an environmentally friendly self-circulating condensing boiler unit disclosed in Chinese patent application CN211575522U, record: simple structure, easy operation, heat in the flue gas can be utilized through the condenser to preheat the water to be heated, reduce gas consumption, and at the same time achieve water recycling to prevent waste of water resources, the cooled flue gas is introduced into the filter chamber through the filter tube, and then the flue gas is filtered through the first filter plate, the second filter plate and the third filter plate to prevent the low-temperature flue gas from being directly discharged into the air to cause environmental pollution, making the condensing boiler more environmentally friendly when in use.

[0004] When the above-mentioned gas condensing boiler unit is in use, since the condenser tube is vertically erected in the processing pipe, and the processing pipe is also provided with a fan and a wind collecting hood, the flue gas will be bifurcated when it contacts the front end of the condenser tube, and then will not contact the rear half of the condenser tube. The flue gas in the processing pipe will be directly discharged from the filter chamber, resulting in low preheating efficiency of the water in the condenser tube, and the heat in the flue gas is not completely absorbed, resulting in heat waste. Moreover, after the filter plate in the filter chamber has been used for a period of time, dust, dirt or other impurities will accumulate on the filter plate, causing blockage, affecting air circulation, and the filtration efficiency will decrease, making it impossible to effectively remove pollutants in the air.
