Summary of the Utility Model

[0003] In order to solve the technical problems of unstable humidifying flow and incomplete sewage discharge in the water tank humidifying water supply in the prior art, the present application proposes a water tank sewage discharging and spraying system, which solves the above technical problems.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] The utility model provides a water tank sewage discharging and spraying system, including: a water tank; a first pipeline, on which a first water pump is configured, the water inlet of the first water pump is communicated with the water tank, the water outlet of the first water pump is communicated with a filter, the downstream of the filter is communicated with a heat exchanger, the downstream of the heat exchanger is communicated with a flow meter, the downstream of the flow meter is communicated with a liquid distributor for spraying, and the water sprayed out from the liquid distributor flows back into the water tank; a second pipeline, on which a second water pump is configured, the water inlet of the second water pump is communicated with the bottom of the water tank, the water outlet of the second water pump is communicated with a water flow switch, and the downstream of the water flow switch is communicated with an external drainage port.

[0006] Further, the first pipeline is arranged in the box body, and the water sprayed out from the liquid distributor of the first pipeline flows back into the water tank through the bottom plate of the box body.

[0007] Further, the heat exchanger is a plate heat exchanger.

[0008] Further, the flow meter is a vortex flow meter.

[0009] Based on the above technical solution, the technical effects that the utility model can achieve are as follows:

[0010] The water tank sewage spraying system of the present utility model pumps water from the water tank through a first water pump, passing through a filter. After the filter becomes dirty and blocked, the water flow rate decreases. A flow meter is added upstream of the liquid distributor for spraying to detect the water flow rate, so as to remind to replace the filter, avoid insufficient humidification water flow rate. At the same time, a second water pump configured on the second pipeline can drain the dirty sewage in the water tank, eliminate the dirt at the bottom of the water tank, avoid sediment sludge from polluting the system, and at the same time avoid the damage of bacterial pollution, reduce the spread of bacteria, increase the drainage speed, make the water drain completely. Reasonable humidification and drainage control can reduce energy consumption and reduce the impact on the environment, meeting the requirements of energy conservation and environmental protection, and solving the technical problems of unstable humidification water supply flow rate and incomplete sewage discharge in the prior art.
