Description
Technical field
The utility model relates to a kind of energy-saving device of boiler, and is especially relevant with the normal pressure phase transformation energy-saving hot water generator that utilizes the boiler exhaust gas waste heat.
Background technology
In boiler industry, for avoiding heated surface at the end of boiler (as air preheater) that cold end corrosion takes place, the exhaust gas temperature of general industry boiler design is usually greater than 150 ℃, that have even up to 200 ℃, the exhaust gas temperature of organic heat carrier (conduction oil) boiler is more than 300 ℃, the exhaust gas temperature of large power plant boiler design also has 120-160 ℃, also has a large amount of middle low-temperature heat quantities not to be utilized, and energy waste is huge.
Summary of the invention
The purpose of this utility model provides a kind of safe, energy-efficient, corrosion-resistant, wear-resistant, not stifled ash, non-scaling, the normal pressure phase transformation energy-saving hot water generator that utilizes the boiler exhaust gas waste heat of long service life.
For achieving the above object, the utility model is achieved through the following technical solutions.Utilize the normal pressure phase transformation energy-saving hot water generator of boiler exhaust gas waste heat, comprise evaporimeter, condenser and tube connector, evaporimeter is connected with condenser by tube connector, and evaporimeter is located in the boiler back end ductwork.
The described normal pressure phase transformation energy-saving hot water generator that utilizes the boiler exhaust gas waste heat, its condenser comprises housing, heat exchanger tube, water inlet, delivery port, dewatering outlet, air inlet, the condensate water outlet, safety exhaust unit and tube sheet, heat exchanger tube are located in the housing, the housing below is located in dewatering outlet and condensate water outlet, air inlet and safety exhaust unit are located at the housing top, and heat exchanger tube is located on the tube sheet of both sides, and heat exchanger tube is the oblique symmetric form in both sides and distributes.
The described normal pressure phase transformation energy-saving hot water generator that utilizes the boiler exhaust gas waste heat, its safety exhaust unit be by tube connector, safety valve, and Pressure gauge and air bleeding valve are formed, and safety valve and Pressure gauge are located on the tube connector, and air bleeding valve is located at the exit of tube connector.
The utility model compared with prior art has following advantage: (one) is because the evaporimeter heat exchanger tube adopts the membrane type pipe, and phase-change heat-exchange, the outer enamel that is coated with of pipe, or heat exchange tube material adopts 09Crcusb, so have corrosion-resistant, wear-resistant, resistive connection is grey, stifled ash, compact conformation, good effect of heat exchange, characteristics such as flue gas resistance is little; (2) be that condenser adopts the normal pressure phase-change heat-exchange, so have characteristics such as safe, energy-efficient, compact conformation; (3) be to have realized separating of evaporimeter and condenser, help convenient the installation; (4) be owing to adopt the phase-change heat-exchange technology, thus this hot water generator exothermic coefficient is big, heat exchange efficiency is high, not scaling, do not produce characteristics such as oxygen corrosion, safe and reliable, long service life.
