Embodiment Construction
[0017] See Figure 1-Figure 3 , A medium-pressure boiler with a fully automatic water adding device, which includes a boiler body 6, a residual pressure and waste heat recovery tower 5 is arranged on the boiler body 6, a water pipe 27 is connected to the waste heat recovery tower 5, and the mouth of the water pipe 27 is installed Float controller 16, in the waste heat recovery tower 5, there are No. 1 water addition tank 12, No. 2 water addition tank 25 and soda water conversion tank 10. The lower part of the soda water conversion tank 10 has a third water inlet 28, and the bottom of the soda water conversion tank 10 is connected to the boiler The waste heat return pipe 29 of the body 6 and the mouth of the waste heat return pipe 29 are equipped with a check valve 9. The No. 1 water filling tank 12 and the No. 2 water filling tank 25 are respectively equipped with booster pipes 14 and 14 from the steam in the boiler body 6 The second booster pipe 23 is controlled by the No. 1 ta...

The utility model relates to a medium-pressure boiler provided with a full-automatic water adding device, comprising a boiler body which is provided with an excess pressure and heat recovery tower that is internally connected with a tap water pipeline provided with a floating ball controller at a pipe orifice; the excess heat recovery tower is internally provided with three tanks, wherein the lower part of a steam-water conversion tank is provided with a No. 3 water inlet, and the bottom thereof is connected with an excess heat return water pipe provided with a check valve; the two water adding tanks are internally provided with ascending pipes and controlled by pressure increasing valves, provided with water adding outlets and connected with water adding valves as well as provided with pressurizing spaces and respectively provided with emptying pipes and exhaust check valves; the steam-water conversion tank is internally provided with a plurality of muffling pipes, the bottom is provided with a steam-water conversion hole which is communicated with the ascending pipes, and a steam conversion valve is used for controlling steam-water conversion; and the valves implement automated procedures by a small relay and a time relay. The medium-pressure boiler utilizes the self steam pressure to add water, uses the physical principle that the steam is light and the water is heavy, and adopts the natural flow direction of high-low difference to automatically add water, thus recovering the excess heat of the boiler and saving energy.
Description
Technical field [0001] The invention relates to a boiler, in particular to a low-pressure boiler with a fully automatic water adding device. Background technique [0002] Since the British Watt invented the steam engine for more than two hundred years, all boiler water refilling is done by motors and water pumps that can achieve greater than the boiler steam pressure. With the rapid development of modern industry, not only the industrial industries that use steam as power or heat exchange have become broader, but the capacity of their boilers has also increased. Although high-tech and new materials have solved the problems of high-power motor manufacturing technology and high-temperature and high-pressure water pump materials, they have failed to change the method of boiler water supply, which has caused the boiler's electric pump water supply method to continue to be used today. A high-pressure boiler is like a 100-ton boiler. The power of a single motor of its feed pump needs ...
