Electrostatic lampblack purifying device with fire extinguishing device

Abstract

The invention relates to an electrostatic lampblack purifying device capable of automatically sprinkling to extinguish fire, which can overcome the problem that the traditional electrostatic lampblack purifying device with a fire-fighting mechanism can not be protected in power-cut. The electrostatic lampblack purifying device comprises a shell, a front reducing air duct, a back reducing air duct, a direct-current high-voltage power supply, a honeycomb cylindrical electric field, a control box and a water-control sprinkling fire-extinguishment device, wherein the front end of the shell is hermetically connected with the front reducing air duct, the back end of the shell is hermetically connected with the back reducing air duct, and the front reducing air duct is further provided with a fireproof valve which is connected with a lampblack inlet and a direct exhaust valve through a tee air duct. Because the front end of the device is provided with the fireproof valve and the direct exhaust valve, an overtemperature control circuit can automatically close the fireproof valve and open the direct exhaust valve to exhaust lampblack when the temperature inside the device is detected beyond a set temperature. As a hydraulic control valve is adopted, fire-fighting water is opened by a mechanical device, therefore, flame detection and fire-extinguishment work can be normally carried out in power cut condition compared with a power-controlled fire-fighting valve.

Description

technical field [0001] The invention relates to the technical field of electrostatic oil fume purification, in particular to an electrostatic oil fume purification equipment with a fire extinguishing device. technical background [0002] Due to the advantages of high removal efficiency, convenient operation and management, and strong adaptability, the electrostatic oil fume purification equipment has been widely used in the treatment of oil fume exhaust gas and dust in various industrial fields. [0003] Existing electrostatic oil fume purification equipment with fire-fighting mechanism such as patent No. 03242233 at present. Disposable products need to be replaced or re-added fire extinguishing agent after use, and if the fire source is not generated inside the purifier, the safety of the equipment cannot be guaranteed; another electrostatic purification equipment with a fire protection mechanism such as the patent number ZL200720054539.0 "with The fire-fighting system of ...
