The invention discloses a boiler gray
water treatment and recycling device. The device comprises a tank shell, three-stage reaction zones, a
sedimentation zone and a clear water zone are arranged in the tank shell, a water inlet is arranged in a
primary reaction zone, the lower part of the
primary reaction zone is provided with a water passing port communicated with a secondary
reaction zone, thesecondary
reaction zone is communicated with the upper part of a
tertiary reaction zone, the lower part of the
tertiary reaction zone is communicated with the
sedimentation zone, the lower part of thesedimentation zone is provided with a mud collection zone and a mud
discharge pipe, the upper part of the mud collection zone is provided with an inclined
pipe sedimentation zone, the upper part of the inclined
pipe sedimentation zone is provided with an overflow tank communicated with a
water discharge tank, the lower part of the clear water zone is provided with a filter bin, the top of the filter bin is connected to an automatic
backwashing device, the lower part in the filter bin is provided with a filter zone, the bottom of the filter zone is provided with a water drain port communicatedwith the clear water zone, the clear water zone is connected to a
water storage tank through a water outlet pipe, the
water discharge tank is communicated with the filter bin through a downcomer, thetail end of the downcomer is provided with a guide cover and the upper part of the guide cover is communicated with the
water discharge tank through a gas
discharge pipe. The boiler gray
water treatment and recycling device has a
small footprint and less water usage.
