Description

Filtering and descaling device for boiler makeup water Technical Field The utility model relates to the technical field of water treatment, in particular to a filtering and descaling device for boiler makeup water. Background Most of heating systems of heating companies in northeast areas adopt a two-ring design, water is supplemented by a hot water heating furnace from underground water, and the water is connected with a primary net backwater main pipe through a sodium ion exchanger and enters a hearth water cavity together. The water cavity of the hearth is provided with a bundling pipe or a boiler coil, and water in the bundling pipe is primary net circulating water. And the backwater of a heating user is fed to the circulating pump to the water heater through the main heat supply network backwater pipe, and is fed to the user for heat exchange after being heated to the main primary heat supply network water supply pipe, so that the whole process of primary network circulating water heating and backwater heating is completed. The primary network has entered the aging period with the increase of the service life, and the accidents of running, overflowing, dripping and leaking during the heating are frequent. After the annual heating period is over, the system equipment cannot be subjected to water seal maintenance, and the primary pipe network pipeline is subjected to water drainage, emptying and maintenance, so that the inner wall of the pipeline after water drainage is severely oxidized and corroded. When water is injected before the beginning of the annual heating period, iron rust in the inner wall of the primary pipe network falls off, the iron rust content in water is very serious, the iron ion content reaches 31.5mg/l when the iron rust content is highest, the corrosion degree of a pipeline is quite serious, the safe operation of system equipment is further threatened, the service life of the primary pipe network system equipment is also reduced, great hidden danger is caused for the safe heating of enterprises, and the enterprise operation cost is increased. Disclosure of utility model In view of the above-mentioned shortcomings and disadvantages of the prior art, the present utility model provides a filtering and descaling device for boiler makeup water, so as to solve the problem of high iron content of boiler scale deposition in the prior art. In order to achieve the above purpose, the main technical scheme adopted by the utility model comprises the following steps: The utility model provides a filter scale removal device for boiler makeup water, includes epitheca, inferior valve, and the epitheca is fixed to be set up in inferior valve upper portion, and epitheca, inferior valve inside intercommunication each other, epitheca top is equipped with the delivery port, is equipped with the booster pump on the delivery port, and epitheca inside is by supreme impeller seat, impeller and the scale removal net of catalyst alloy of having set gradually down, inferior valve bottom is equipped with the water inlet, and inferior valve inside is equipped with the filter material that is used for filtering aquatic impurity. Further, a pressure sensor is arranged on a pipeline behind the booster pump, and the booster pump is electrically connected with the pressure sensor. Further, the descaling net is provided with a plurality of layers from bottom to top in the upper shell. Further, the bottom of the lower shell is provided with supporting legs.
