Description
Technical Field
The utility model relates to an ammonium phosphate crystal waste water treatment technical field specifically is an ammonium phosphate crystal vacuum pump waste water recovery control system.
Background
The method has the following defects that ① the sewage enters the large sewage tank for unified treatment, the treatment load of the large sewage tank is increased, and simultaneously the amount of the discharged sewage exceeds the standard, ② the vacuum pump has certain influence on a cooling water system due to frequent start/stop, ③ the sewage generated by the vacuum pump contains a certain amount of sewage with larger water content and slight pollution degree and directly enters the sewage tank for discharging, and a large amount of water is wasted ④ the equipment service life is short and the failure rate is high due to frequent start/stop of the vacuum pump.
Disclosure of Invention
In order to solve the technical problem, the utility model provides an ammonium phosphate crystal vacuum pump waste water recovery control system, through the level gauge in cooling water pool and install the converter at the vacuum pump additional, can be balanced and automatic carry waste water to cooling water system's condenser tube, energy-conservation has prolonged equipment life simultaneously.
The utility model discloses the technical scheme who takes does:
ammonium phosphate crystal vacuum pump waste water recovery control system, including setting up the level gauge in the cooling water pond, the converter is connected to the level gauge, and the vacuum pump is connected to the converter, and the outlet pipe connection condenser tube of vacuum pump, condenser tube and cooling water pond intercommunication.
And a check valve is arranged on an outlet pipeline of the vacuum pump.
The liquid level meter is a BM26 magnetic turning plate liquid level meter.
The frequency converter is a Siemens MM440 frequency converter.
The utility model relates to an ammonium phosphate crystal vacuum pump waste water recovery control system, the technological effect as follows:
1: the waste water generated by the vacuum pump is completely merged into the cooling water pool without any overflow. And transfer links such as an underground collection tank, a large sewage pool in a factory and the like are omitted.
: meanwhile, the rotating speed of the vacuum pump is controlled by the liquid level meter, and the output wastewater amount of the vacuum pump is basically consistent when the vacuum pump works stably under negative pressure, so that the influence on a cooling water system is small.
: the frequency converter is adopted to intelligently control the vacuum pump, so that the frequent start/stop is avoided, the service cycle of the equipment is prolonged, and the labor intensity is reduced.
Drawings
Fig. 1 is a schematic view of the control system of the present invention.
Detailed Description
As shown in figure 1, ammonium phosphate crystal vacuum pump waste water recovery control system, including setting up level gauge 2 in cooling water pool 1, converter 3 is connected to level gauge 2, and vacuum pump 4 is connected to converter 3, and condenser tube 5 is connected to the outlet pipeline of vacuum pump 4, and condenser tube 5 communicates with cooling water pool 1.
And a check valve 6 is arranged on an outlet pipeline of the vacuum pump 4.
The liquid level meter 2 is a BM26 magnetic turning plate liquid level meter.
The frequency converter 3 is a Siemens MM440 frequency converter.
The implementation steps are as follows:
the liquid level meter 2 monitors the liquid level height of the cooling water pool 1 in real time, outputs a 4-20mA analog quantity signal, uses the analog quantity signal, is directly connected to the frequency converter 3 without a PLC (programmable logic controller), and when the cooling water pool 1 is at a higher liquid level, the frequency converter 3 drives the vacuum pump 4 to rotate at a low rotating speed; when the cooling water pool 1 is at a lower liquid level, the frequency converter 3 drives the vacuum pump 4 to operate at a low rotating speed and a high rotating speed; the frequency converter 3 realizes PID control on a motor of the vacuum pump, and the vacuum pump 4 realizes dynamic balance type conveying of wastewater to the cooling water pool 1, so that the vacuum pump 4 is prevented from being started/stopped frequently. The cooling water pool 1 has large water quantity and slight pollution degree, but directly discharges a large amount of fresh water to waste, and then adopts a treatment method mainly for perfecting a circulating cooling water system. In addition, in order to prevent the water of the cooling water pipe 5 from flowing back into the outlet pipeline of the vacuum pump 4, a check valve 6 is arranged to block the water from flowing back in one direction.
