Rainwater dynamic balance type fire water tank water purifying device

Abstract

The invention relates to a rainwater dynamic balance type fire water tank water purifying device. The device comprises a fire water tank, a rainwater collecting tank, a self-priming centrifugal pump and a double-layer filter material filter, the top of the rainwater collecting tank is connected with the first rainwater riser, the fire water tank is connected with the water inlet of the first rainwater riser, the water outlet tube of the water tank is provided with a float ball valve, a solenoid valve and a second rainwater riser are arranged at the bottom of the rainwater collecting tank, twoends of the solenoid valve are respectively connected with the rainwater collecting tank and the second rainwater riser, one end of the self-priming centrifugal pump is connected with the rainwater collecting tank, the other end of the self-priming centrifugal pump is connected with the double-layer filter material filter, the double-layer filter material filter is connected with the fire water tank, and a support is arranged at the bottom of the double-layer filter material filter. The device solves the problems of poor quality of long-term stored water in the fire water tank of a high-rise building and high energy consumption in water renewing in a traditional way, and utilizes initial rainwater to realize the purpose of purifying water in the fire water tank on the premise of ensuring the dynamic balance of the water volume of the fire water tank.

Description

technical field [0001] The invention belongs to the technical field of water quality purification, and in particular relates to a rainwater dynamic balance fire water tank water purification device. Background technique [0002] The fire water supply is the guarantee of building safety. The fire water tank water is the initial water supply source of the sprinkler system inside the building. important role. [0003] At present, the fire water supply system of the building is set separately. The first filling of the fire water tank is supplied by the fire pump. The water volume is designed in strict accordance with the specification requirements. The water quality requires no corrosion, no large impurities, and no influence on normal use. Due to the low probability of building fires, after the fire water tank is filled with water for the first time, if it is not used, the stored water is usually not replaced for a long time. In this case, the water quality will inevitably det...

Problems solved by technology

Due to the low probability of building fire, after the fire water tank is filled for the first time, if it is not used, the stored water is usually not replaced for a long time. In this case, the water quality will inevitably deteriorate and bacteria will grow, which will seriously affect the normal use.

Some of them are simply treated by adding disinfectants. This method leads to sedimentation in the lower part of the fire water tank. The sediments exist for a long time and are difficult to clean up completely. Most of them do not take any water purification measures, which makes the water quality of the fire water tank have great hidden dangers.
