The invention relates to the field of comprehensive treatment of flue gas, in particular to a system for detecting a real-time pH value of condensate water from a natural gas boiler and neutralizing and discharging wastewater. The system comprises a gas inlet pipe, a flue gas channel, a NaOH water tank, a pH value controller, pH value sensors and a neutralizing tank, wherein the gas inlet pipe iscommunicated with a gas inlet end of the flue gas channel, the NaOH water tank is communicated with the flue gas channel through a second connection pipe, the bottom of the flue gas channel is provided with a NaOH water solution tank, and the pH value controller is connected with the pH value sensors and electromagnetic valves through transmission lines. A first liquid inlet of the neutralizing tank is communicated with an overflow opening of the NaOH water solution tank through an overflow pipe, and a second liquid inlet of the neutralizing tank is communicated with a primary condensate waterpipe. Through the real-time value monitoring structure composed of the NaOH water tank, the NaOH water solution tank, the pH value controller, the pH value sensors and the neutralizing tank, the pH value controller monitors the pH value of the NaOH water solution tank and the pH value of the neutralizing tank in real time, when the pH values fluctuate, the flow rate of the NaOH water tank is controlled by the corresponding electromagnetic valve, and dynamic equilibrium of the whole system area is kept.
Description
technical field [0001] The invention relates to the field of flue gas comprehensive treatment, in particular to a natural gas boiler condensed water pH real-time value detection and waste water neutralization treatment discharge system. Background technique [0002] With the popularization and use of natural gas condensing boilers, the flue gas emitted by them contains NO 2 Such acidic gases cause certain harm to the environment. At present, acidic gases can be adsorbed and removed by spraying some alkaline solutions, but in actual use, real-time pH value detection has not been achieved, resulting in the failure of the entire system to achieve dynamic equilibrium. The waste liquid after neutralization has not been uniformly treated, which is inconvenient for management. Contents of the invention [0003] The present invention can absorb and remove acid gas by spraying some alkaline solutions, but in actual use, the pH real-time value detection is not done, so that the who...
