DETAILED DESCRIPTION

The present invention relates to a water cleaning device for welding fume purification equipment. The cleaning device of the present invention makes full use of circulating water to clean and wash the electrostatic precipitator, which can improve the utilization rate of water resources and better ensure the purification performance of the electrostatic precipitator. The present invention belongs to the field of environmental dust removal technology. The electrostatic precipitator selected by the present invention is the electrostatic precipitator disclosed in application number CN202322153499.7.

The water cleaning device uses the main pipeline to supply water, and multiple devices are cleaned in sequence. The cleaned sewage is discharged to the sewage main pipe and then transported to the sewage pool. The sewage pool also has a sedimentation function. After the sewage is fully precipitated, it is transported to the clean water tank through the filter and the filter water pump for the next cleaning. The entire cleaning process is automatically executed by the electromechanical equipment according to the set program. The following will be further explained in combination with the embodiments and drawings.

Example

A water-cleaning electrostatic precipitator comprises an electrostatic precipitator 1 and a circulation unit, wherein the electrostatic precipitator 1 comprises an inlet for connecting to a clean water source outlet of a clean water pump 4, an outlet for connecting to a sewage inlet of a sewage pump 13, a dust-containing gas 2 inlet and a clean air 3 outlet; the dust-containing gas 2 enters the electrostatic precipitator 1 through the dust-containing gas 2 inlet to separate the dust-containing gas 2 and smoke, and the dust-containing gas 2 is discharged through the clean air 3 outlet; the smoke is mixed into water to form sewage;

The circulation unit includes a sewage discharge unit and a water inlet unit. The sewage discharge unit includes the sewage pump 13 that pumps the sewage in the electrostatic precipitator 1 into the sewage tank 12 through the sewage discharge pipe; the water inlet unit includes a filter water pump 9 that filters and pumps the sewage in the sewage tank 12 into the clean water tank 10, and the water source in the clean water tank 10 flows into the water pipe through the clean water pump 4 and is pumped to the electrostatic precipitator 1; a clean water source interface 11 for water injection is provided above the clean water tank 10; the sewage discharge pipe includes a sewage discharge branch pipe 6 and a sewage discharge main pipe 7, and the sewage in the sewage discharge branch pipe 6 is collected and flows into the sewage discharge main pipe 7 to pass into the sewage tank 12; the sewage pump 13 is arranged on the sewage discharge branch pipe 6; an electromagnetic water valve 5 is provided on the pipeline connecting the clean water pump 4 and the electrostatic precipitator 1 and the sewage discharge pipe.

In a further optimization scheme, 1 to 4 sewage branch pipes 6 are arranged on each sewage trunk pipe 7 .

In a further optimization scheme, three sewage branch pipes 6 are arranged on each sewage trunk pipe 7 .

In a further optimization scheme, a temporary sewage outlet 8 is further provided on the sewage outlet of the sewage pump 13 .

In a further optimization scheme, the water pipe includes a water main pipe 14 and a water branch pipe 15; the clean water pump 4 pumps the water source in the clean water tank 10 through the water main pipe 14 to flow into the water branch pipe 15; the clean water pump 4 is arranged on the water branch pipe 15.

In a further optimization scheme, 2-8 water delivery branch pipes 15 are arranged on each of the water delivery main pipes 14 .

In a further optimized solution, six water delivery branch pipes 15 are arranged on each of the water delivery main pipes 14 .

During the working process of the present invention, first, the water-cleaning electrostatic precipitator is started, and the water source in the clean water tank 10 flows into each water delivery branch pipe 15 through the water delivery main pipe 14, and enters the electrostatic precipitator 1 through the clean water pump 4. The dust-containing airflow 2 enters the electrostatic precipitator 1 through the air inlet of the electrostatic precipitator 1. The electrostatic precipitator 1 starts to work, cleans the dust-containing airflow 2 into clean air 3, and discharges it from the exhaust port of the electrostatic precipitator 1. Then, the sewage pump 13 extracts the sewage that cleans the dust-containing airflow 2, flows into each sewage drainage branch pipe 6, and then collects it into the sewage drainage main pipe 7, and flows into the sewage tank 12 through the sewage drainage main pipe 7. Finally, the welding smoke will settle at the bottom of the sewage tank 12, and the sewage in the sewage tank 12 will be filtered again by the filter water pump 9 and flow into the clean water tank 10. The water source that flows into the clean water tank 10 will enter the electrostatic precipitator 1 again to clean the dust-containing airflow 2, forming a cycle.

When the circulating cleaning water is insufficient, clean water can be injected through the clean water source interface 11 arranged above the clean water tank.

In addition, a temporary sewage outlet 8 for emergency use is also provided at the sewage outlet of the sewage pump 13 .

Since the water quality requirements for cleaning water of electrostatic precipitator are not strict compared with municipal tap water, only relatively simple filtering treatment of sewage is needed to meet the cleaning needs, reducing unnecessary waste of energy and resources.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
