Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The utility model provides a honeycomb formula flue gas condensing system.
As shown in fig. 1, the system comprises a flue access pipe 1, a heat exchange shell pipe 2, a baffle plate 3, flue gas heat exchange pipes 4, heat exchange tube plates 5, a flue pipe 6, a circulating water pipe 7 and a condensed water discharge pipe 8, wherein the flue pipe 6 is connected with the flue access pipe 1, the heat exchange tube plates 5 are arranged on one sides of the flue access pipe 1 far away from the flue pipe 6, the heat exchange shell pipe 2 is arranged between the two heat exchange tube plates 5, a plurality of flue gas heat exchange pipes 4 are connected between the two heat exchange tube plates 5, the flue gas heat exchange pipes 4 penetrate through the baffle plate 3, the circulating water pipe 7 is connected to two ends of the heat exchange shell pipe 2, and the condensed water discharge pipe 8 is connected below the flue access pipe 1; the heat exchange shell tube 2, the baffle plate 3, the flue gas heat exchange tube 4 and the circulating water tube 7 are connected to form a honeycomb type high-efficiency flue tube heat exchanger.
The flue gas heat exchange tube is used for cooling flue gas and condensing water vapor in the flue gas, so that the exhaust temperature of the flue gas and the water content in the flue gas are greatly reduced; the final result of cooling the flue gas and reducing the water content in the flue gas is that the circulating water absorbs a large amount of heat of the flue gas and condensation heat of water vapor;
the flue gas passes through the flue pipe of the flue gas heat exchange pipe and exchanges heat with the circulating water through the pipe wall of the flue pipe;
the smoke heat exchange tube absorbs heat energy discharged by smoke by water, cold water passes through the heat exchange shell tube and absorbs heat energy of the smoke to form hot water, and the hot water with the increased temperature is used for life or heating;
the condensed water discharging device of the system discharges the formed condensed water after condensing the water vapor in the flue gas, and the condensed water can be recycled.
When the system is applied, one or more than one of the systems can be used in parallel or in series according to the size of a boiler.
During installation, the entire system is connected into the boiler flue. High-temperature flue gas generated by the boiler passes through the flue gas heat exchange tube 4, and heat in the flue gas is transferred to circulating water outside the tube wall of the flue gas heat exchange tube 4 through the flue gas heat exchange tube 4, so that the boiler is used for daily life or heating. Condensed water formed after the temperature of the flue gas in the flue gas heat exchange tube 4 is reduced is discharged through a condensed water discharging device.
Because the temperature of flue gas is higher, the heat exchange tube wall is thin, and heat exchange efficiency is high, so entire system heat transfer temperature difference is very little.
