Abstract

Disclosed is a combined water tank type boiler waste heat recovery device. A heat absorption water tank is arranged on the combined water tank type boiler waste heat recovery device. A heat absorption water tank water inflow tube and a heat absorption water tank water outflow tube are arranged on the heat absorption water tank. The combined water tank type boiler waste heat recovery device is characterized in that a u-shaped flue is arranged in the heat absorption water tank, multiple metal cooling sheets are arranged on the u-shaped flue, a smoke inlet of the u-shaped flue is connected with a boiler chimney, and a smoke outlet of the u-shaped flue is connected with a draught fan; a hot water reserve tank is further arranged on the combined water tank type boiler waste heat recovery device; a thermal-insulation layer is arranged outside the hot water reserve tank, a hot water reserve tank water inflow tube and a hot water reserve tank water outflow tube are arranged on the hot water reserve tank, and a thermal-insulation layer is arranged around the heat absorption water tank; a temperature control valve is arranged on the heat absorption water tank water inflow tube of the heat absorption water tank, and a temperature control water pump is further arranged between the heat absorption water tank water outflow tube of the heat absorption water tank and the hot water reserve tank.

Description

technical field [0001] The invention relates to a boiler waste heat recovery device, in particular to a composite water tank type boiler waste heat recovery device. Background technique [0002] Traditional boiler waste heat recovery devices generally use a hot water tank outside the chimney to absorb the heat of the chimney by the thermal fusion of water. Although this method can also recover heat, its recovery efficiency is low and energy waste is large. Contents of the invention [0003] The object of the present invention is to provide a waste heat recovery device for composite water tank boilers with simple structure and high efficiency. [0004] The present invention utilizes a heat-absorbing tank and a reserve heat-water tank. When the water in the heat-absorbing tank reaches the set temperature, the temperature-controlled water pump is started to inject hot water into the reserve heat-water tank for storage, and the two water tanks are installed outside Insulation...
