High-pressure boiler provided with full-automatic water adding device

Abstract

The utility model relates to a high-pressure boiler provided with a full-automatic water adding device, comprising a boiler body which is provided with a water tower that is internally connected with a tap water pipeline provided with a self-contained floating ball controller; the water tower that is internally provided with three water adding tanks, the upper parts of which are respectively connected with a steam ascending pipe, and the steam ascending pipes that are arranged under the water tank are respectively connected with an emptying valve laterally, connected with a steam pipeline andcontrolled by the respective steam ascending pipe; the lower parts of the three water adding tanks are respectively connected with the bottom of the water tower and controlled by a water feeding valve inside the tank; the bottoms of the three water adding tanks are respectively connected with a water adding pipe of the boiler and controlled by a water adding valve; the pipelines are arranged at the lower parts, communicated with each other and controlled a steam-water conversion valve; an excess pressure and heat return water pipe is connected to the bottom of the water tower from the boiler body, and a check valve is installed at an outlet of the excess pressure and heat return water pipe; and the valves implement automated procedures by a small relay and a time relay. The high-pressure boiler utilizes the self steam pressure to automatically add water and recovers the excess heat of the boiler, thus saving energy.

Description

technical field [0001] The invention relates to a boiler, in particular to a high-pressure boiler with a fully automatic water adding device. Background technique [0002] Since the British Watt invented the steam engine for more than 200 years, all boiler water additions have relied on motors and water pumps that can achieve greater than the steam pressure of the boiler. With the rapid development of modern industry, not only the industries that use steam as power or heat exchange are more extensive, but the capacity of boilers is also increasing. 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 not changed the method of boiler water supply, resulting in the electric pump water supply method of boilers being used until now. For a high-pressure boiler such as a 100-ton boiler, the power of a single motor of its feed pump needs 3200 kWh, and the an...
