Description

Rainwater automatic collection system of recycling

Technical Field

The utility model relates to a rainwater recovery system field of recycling, especially a rainwater automatic collection system of recycling.

Background

In chemical production, public works need to consume a large amount of water resources, particularly a circulating water system, and a large amount of circulating water is evaporated and consumed during operation. The general factory uses industrial water for the consumption and supplement of circulating water, the consumption of the industrial water is large, the cost price is high, and the production cost is high; the rain season time of the environment of the plant area is long, the precipitation is large, the rainwater treatment cost is high, and the treatment pressure of a sewage station is large; finally, in rainy seasons, the operation pressure of public works is high, and the requirement of high-load production cannot be met.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's shortcoming, provide a rainwater automatic collection system of recycling, can reduce the handling capacity of the unqualified rainwater of mill, reduce rainwater treatment cost, reduce sewage station operating pressure, for high load production provides the guarantee, collect simultaneously qualified rainwater and supply water reuse as the circulating water, reduce the public works water resource consumption of mill, reduction in production cost.

The purpose of the utility model is realized through the following technical scheme: the utility model provides a rainwater automatic collection system of recycling, includes the rainwater pipe network, the catch basin, the cistern, the level gauge, the immersible pump, automatic control system and COD on-line monitoring ware, the rainwater pipe network inserts the catch basin, COD on-line monitoring ware water inlet sets up at the catch basin bottom of the pool, the cistern passes through cistern pipeline and catch basin bottom intercommunication, be provided with the valve on the cistern pipeline, the immersible pump sets up at the catch basin bottom of the pool, and the outlet conduit on the immersible pump inserts the sewage station, the level gauge sets up in the catch basin side, and the automatic control system input is connected with level gauge and COD on-line monitoring ware, and the automatic control system output is connected with immersible pump and valve. In rainy days, rainwater in a factory is intensively discharged to a water collecting tank through a rainwater pipe network, a liquid level meter transmits detected liquid level information to an automatic control system, the automatic control system controls a COD (chemical oxygen demand) online monitor to measure rainwater indexes and perform qualified judgment, and then the judgment result is fed back to the automatic control system, if the rainwater indexes are unqualified, the automatic control system starts a submersible pump to discharge the rainwater in the water collecting tank to a sewage station for treatment, so that environmental pollution is avoided; if the rainwater index is qualified, the automatic control system opens the valve to drain water to the reservoir so as to relieve the rainwater treatment pressure and simultaneously serve as circulating water to supplement water for recycling. And if the liquid level meter does not detect the liquid level information, stopping the operation of the whole system.

Preferably, the automatic control system is provided with an alarm device, a lighting switch, a monitoring switch and a reservoir valve switch.

Preferably, the automatic control system adopts a PLC control system.

Preferably, the liquid level meter adopts an outer liquid level meter.

The utility model has the advantages of it is following:

the automatic rainwater collecting and recycling system can reduce the treatment capacity of unqualified rainwater in a factory, reduce the rainwater treatment cost, reduce the operating pressure of a sewage station, provide guarantee for high-load production, collect qualified rainwater to be recycled as circulating water supplementing water, reduce the water resource consumption of public works in the factory and reduce the production cost.

Fig. 1 is a schematic structural view of the present invention;

in the figure: 1-rainwater pipe network, 2-water collecting tank, 3-water storage tank, 4-liquid level meter, 5-submersible pump, 6-automatic control system, 7-sewage station, 8-COD on-line monitor, and 9-valve.

Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1, a rainwater automatic collection system of recycling, including rainwater pipe network 1, catch basin 2, cistern 3, level gauge 4, immersible pump 5, automatic control system 6 and COD on-line monitoring ware 8, rainwater pipe network 1 inserts catch basin 2, COD on-line monitoring ware 8 water inlet sets up at catch basin 2 bottoms of ponds, cistern 3 passes through cistern pipeline and catch basin 2 bottoms intercommunication, be provided with valve 9 on the cistern pipeline, immersible pump 5 sets up at catch basin 2 bottoms of ponds, and the outlet conduit on the immersible pump 5 inserts sewage station 7, level gauge 4 sets up in catch basin 2 sides, and automatic control system 6 input is connected with level gauge 4 and COD on-line monitoring ware 8, and automatic control system 6 output is connected with immersible pump 5 and valve 9.

The working process of the utility model is as follows:

in rainy days, rainwater in a factory is intensively discharged to a water collecting tank 2 through a rainwater pipe network 1, a liquid level meter 4 transmits detected liquid level information to an automatic control system 6, the automatic control system 6 controls a COD (chemical oxygen demand) online monitor 8 to measure rainwater indexes and perform qualified judgment, a judgment result is fed back to the automatic control system 6, if the rainwater indexes are unqualified, the automatic control system 6 starts a submersible pump 5, and rainwater in the water collecting tank 2 is discharged to a sewage station 7 for treatment, so that environmental pollution is avoided; if the rainwater index is qualified, the automatic control system 6 opens the valve 9 to drain water to the water storage tank 3 so as to relieve the rainwater treatment pressure and simultaneously serve as circulating water to supplement water for recycling. If the liquid level meter 4 does not detect the liquid level information, the whole system stops running.
