Description

Electrostatic smoke purification equipment

technical field

The utility model relates to the technical field of smog purification, in particular to an electrostatic smog purification device.

Background technique

An existing electrostatic smog purification equipment consists of a casing, a main control box, multiple DC high-voltage power supplies, and multiple wide-spaced honeycomb cylindrical electric fields installed in the casing. One side of the casing is equipped with 1-3 fans for inspection and maintenance. There is an oil discharge hole on the side of the middle door and the bottom of the casing to discharge waste oil outward. The so-called wide-spacing honeycomb cylindrical electric field means that the distance between the cathode needle and the anode cylinder is within the range of 175-250mm. It can be seen that the wide-spacing honeycomb cylindrical electric field has a larger volume and requires a higher DC high voltage value, reaching 35KV -90KV, so the DC high-voltage power supply has high cost, large volume, high insulation requirements, and long construction period. In small-scale projects, the wide-spacing honeycomb cylindrical electric field has insufficient dust collection area and low driving speed, so the purification rate is not high and the purification effect is not significant enough. Each wide-space honeycomb cylindrical electric field is powered by a DC high-voltage power supply, and multiple DC high-voltage power supplies are concentrated on the top of the casing, which is inconvenient for maintenance. Because the casing bottom plate is a flat plate, the waste oil cannot be collected and recycled in time.

The purpose of the utility model is to provide an electrostatic smoke purification device with small volume and convenient maintenance, which can obtain high purification efficiency and can collect and recycle waste oil in time.

The technical solution proposed by the utility model is as follows: an electrostatic smog purification equipment, including a casing, a main control box, a DC high-voltage power supply, a plurality of honeycomb cylindrical electric fields, and the main control box is installed on the front side of the casing The casing is equipped with honeycomb cylindrical electric fields arranged in rows and layers, at least one narrow-pitch honeycomb cylindrical electric field is installed in the casing, and each narrow-pitch honeycomb cylindrical electric field is installed in front of the airflow There are porous air-uniform partitions, and small maintenance doors corresponding to each row of narrow-space honeycomb cylindrical electric fields are evenly distributed on one side of the casing. The bottom plate of the casing has an inclination, and the oil discharge port is located on the inclined bottom plate. lowest end.

A front electric box is installed on the outer side of each small inspection door, and a DC high-voltage power supply is installed in the box to supply power to the corresponding row of narrow-spaced honeycomb cylindrical electric fields. The casing is equipped with 1-45 narrow-pitch honeycomb cylindrical electric fields arranged in rows and layers, the number of rows is 1-5, and the number of layers is 1-3. Preferably, an inclined oil sump is arranged in the middle of the bottom plate of the casing, and the oil discharge port is arranged at the lowest end of the inclined oil sump. The distance between the cathode needle and the anode cylinder of the narrow-pitch honeycomb cylindrical electric field is preferably selected within the range of 20-50mm.

Compared with the prior art, the utility model has the following beneficial effects:

(1) The distance between the cathode needle and the anode tube is called the narrow-pitch honeycomb cylindrical electric field below 150mm. Because the utility model has adopted the narrow-pitch honeycomb cylindrical electric field, the distance between the cathode and the anode is selected as 20-50mm. Compared with the existing electrostatic smog purification equipment, under the same volume, the number of honeycomb cylindrical electric fields is larger, the dust collection area is larger, and the air flow it withstands is driven at a higher speed. When 10-25KV DC high voltage is selected, it can Ensure that the corona current density is high, and the dust can be fully charged, ensuring that the equipment reaches a very high purification efficiency of more than 95%. In front of the narrow-spacing honeycomb cylindrical electric field, a porous air-uniform partition is installed, which can filter dust and oil with large particles well, and make the air volume flowing through the anode cylinders of each electric field roughly consistent, thus ensuring Each electric field anode cylinder is fully utilized, which improves the purification efficiency.

(2) Because the utility model designs the bottom plate of the casing into a small slope or stamps an oil collecting groove with a small slope on the bottom plate, the oil discharge port is arranged at the lowest end of the oil collecting groove, which greatly facilitates the collection of waste oil, and The recovered waste oil has high purity and can be recycled.

(3) Since each row of narrow-pitch honeycomb cylindrical electric fields is equipped with a maintenance small door, the corresponding high-voltage DC electric field is installed outside the small door through the front electric box, so it is very convenient for the inspection, maintenance and maintenance of the equipment.

The utility model is mainly suitable for purifying the oil smoke, oil mist and dust produced in the production processes of dyeing and finishing, leather, heat treatment, metal processing, food processing and chemical industries.
