Abstract

A silt filtering device for water used for boilers is disclosed. The device includes a tank body. The two sides of the upper part of the tank body are respectively communicated with a water inlet and a backwashing water outlet. The bottom of the tank body is communicated with a water outlet and a backwashing water inlet. The middle of the tank body is provided with a sand-stone composite filtration layer. The device achieves purification filtration of a water source through the sand-stone composite filtration layer. The device is simple in structure and low in cost and filtration purification effects are good.

Description

technical field [0001] The invention relates to the technical field of boiler water treatment, in particular to a cement sand filter device for boilers. Background technique [0002] In the production of industrial boilers, the water source is generally groundwater or river water. However, the hardness of groundwater or river water is usually high, especially in the dry season when the water volume is small, and the upstream ore washing wastewater flows in, causing the water source to be turbid, and the sediment content in the rainy season is low. Very high, therefore, need to soften the water treatment of the water source. [0003] At present, softening water treatment devices generally use ion exchangers to purify and soften water sources, which is not only costly, but also has a complex structure and is not easy to operate and maintain. Contents of the invention [0004] The object of the present invention is to provide a cement sand filtering device for a boiler, whic...
