Description of the Related Art In a dry type electrostatic precipitator, it is necessary to wash the inside of the apparatus regularly (usually once or twice every six months) in order to perform inspection work and repair work. Conventionally, cleaning wastewater generated by cleaning has been passed through a drainage pit under a dry electrostatic precipitator, purified by a wastewater treatment device, and then discharged into a river or the like. Then, in recent years, the regulation of nitrogen in wastewater has been enforced by the revision of the Enforcement Ordinance of the Water Pollution Control Act in the wastewater standards discharged into rivers.

１程度で処理可能である。Next, a method for treating cleaning and drainage of the dry electrostatic precipitator of the present invention using the apparatus constructed as described above will be explained. Prior to performing inspection work or repair work inside the dry electrostatic precipitator 10, water is sprayed from the cleaning device 20 into the device 10 to wash and wash the inside of the device 10. The washed waste water that has been washed is discharged from the lower end of the hopper 10D of the dry electrostatic precipitator 10 and stored in the storage tank 26. Then, after the inspection work and the repair work are completed and the operation of the dry electrostatic precipitator 10 is started, the supply pump 32 is operated to wash the cleaning wastewater stored in the storage tank 26 from the spray device 28 to the inlet side flue. 12
Spray inside. At this time, the gas temperature of the combustion exhaust gas 16 introduced into the dry electrostatic precipitator 10 through the inlet side flue 12 is, for example, about 130 ° C in the case of a heavy oil boiler, and the gas temperature is 120 ° C. In the following cases, the dust collection performance of the dry electrostatic precipitator 10 is likely to be affected. Therefore, the control device 44 compares the temperatures from the upstream temperature sensor 46 that detects the gas temperature of the cleaning wastewater before spraying and the downstream temperature sensor 48 that detects the gas temperature after spraying, and determines the gas temperature of the spraying gas. The second, so that the drop falls within 10 ° C,
The opening degree of the third solenoid valves 38, 40 is adjusted. As a result, the spray amount of the cleaning drainage can be automatically controlled so as not to affect the dust collection performance of the dry electrostatic precipitator 10. By the way, when the amount of sprayed cleaning wastewater is calculated by a reduction of the gas temperature of 5 ° C, the inlet gas amount of the dry electrostatic precipitator 10 is 80%.
In the case of 10,000 Nm 3 / hour, the spray amount is about 2 t / hour. And, if it is a cleaning drainage of 300 tons, it is 6 to 7
It can be processed in a day, and if it is 1000t of cleaning wastewater, it is 2
It can be processed with about 1.

る。Further, the above-mentioned inlet gas amount (800,00
(0 Nm 3 / hour) is reduced to about 1/2 to 1/3 in the case of night, so the spray amount is adjusted according to the degree of reduction. As described above, according to the method for cleaning and treating drainage of the dry electrostatic precipitator of the present invention, the cleaning drainage generated by washing with water in the apparatus 10 at the time of cleaning the dry electrostatic precipitator 10 is the dry electrostatic precipitator 10 itself. Since it is possible to treat the wastewater, it is not necessary to use a wastewater treatment device for treating the washing wastewater as in the conventional case.

After that, when the second to fourth electromagnetic valves 38, 40, 42 are closed and the first electromagnetic valve 24 is opened to perform the final cleaning with the clean water from the cleaning device 20, the amount of cleaning drainage generated Can be reduced.

However, it can also be used for treating wastewater such as desulfurization equipment wastewater and air heater wastewater. Further, an upstream temperature sensor 46 and a downstream temperature sensor 48 are provided to detect the gas temperature of the combustion exhaust gas,
Although the difference is detected, the downstream temperature sensor 48
Only the gas temperature may be provided so that the gas temperature does not fall below the set temperature.

Therefore, it is not necessary to use a wastewater treatment device for purifying washing wastewater as in the conventional case. This eliminates the facility cost of the wastewater treatment equipment and the running cost of the wastewater treatment.

As a result, a small-scale wastewater treatment device is sufficient, so that the facility cost of the wastewater treatment device and the running cost of the wastewater treatment can be significantly reduced.
