Detailed Description
The invention will be further described with reference to the following drawings and specific embodiments:
as shown in fig. 1 and 2, an explosion-proof dust removal system comprises an air inlet pipe 10, wherein the air inlet pipe 10 is correspondingly communicated with an inert powder feeding pipe 2, the inert powder feeding pipe 2 is correspondingly connected with a spiral powder feeding machine 1, the air inlet pipe 10 is correspondingly communicated with a dust remover 3, the dust remover 3 is correspondingly communicated with a fan 13 through a connecting pipeline 12, the other end of the fan 13 is correspondingly communicated with an air return pipe 8, the dust remover 3 is correspondingly connected with a dynamic pressure detector 6, an explosion suppressor 5 and a flameless explosion venting device 4 are correspondingly arranged on the dust remover 3, and the explosion suppressor 5 is correspondingly electrically connected with the dynamic pressure detector 6.
The dynamic pressure detector 6 can detect the rising rate of the dynamic pressure in the dust remover 3 in real time, monitor whether the chamber of the dust remover 3 explodes or not, and once the explosion is judged, the dynamic pressure detector and the explosion suppressor 5 perform linkage reaction, and the explosion suppressor 5 sprays explosion suppression agent to the chamber of the dust remover 3 within milliseconds to prevent the explosion.
As shown in fig. 3 and 4, an isolation valve 7 is correspondingly disposed on the return air pipe 8. And the air inlet pipe 10 is correspondingly provided with an explosion-proof valve 9. The dynamic pressure detector 6 is arranged on the top of the dust remover 3. The explosion suppressor 5 is provided in the side wall of the dust separator 3. The flameless explosion venting device 4 is arranged at the top of the dust remover 3. And a fan silencing room 11 is correspondingly arranged on the outer side of the fan 13.
Inert dust is continuously fed into an air inlet pipe 10 of the dust remover through an inert powder feeding pipe 2 and a spiral powder feeding machine 1, so that the concentration of explosive dust is reduced, and the probability of explosion is reduced. In practical application, a wind speed sensor can be arranged on the air inlet pipe 10, the wind speed in the pipe is monitored to be not lower than a dust explosion-proof safety standard value, and explosion risks caused by explosion dust accumulation are avoided; a differential pressure sensor is arranged on the dust remover 3, the differential pressure of the filter cylinder is monitored, the back flushing system is started when the differential pressure exceeds a safe range value, explosive dust accumulated on the surface of the filter cylinder is removed, and explosion risks caused by the accumulation of the explosive dust are avoided.
The explosion-proof valve 9 can block pressure and flame when explosion occurs, so that front-end production equipment is protected; the return air pipe is provided with an isolation valve. When explosion happens, pressure and flame are blocked, and personnel and equipment in a workshop are protected;
the explosion suppressor 5 can spray an explosion suppressor to the dust remover to stop explosion and occurrence when detecting that the explosion is about to occur; the dust remover 3 is provided with a flameless explosion venting device 4, so that energy generated by explosion is released when the explosion occurs, the flame is blocked from being sprayed out, and the safety of equipment and personnel is guaranteed.
The existing common scheme has no explosion-proof and explosion-suppression components or only selects one of the explosion-proof and explosion-suppression modes, so that the potential safety hazard of explosion exists when explosive dust is treated, and the safety of personnel and equipment cannot be effectively protected when the explosion occurs. The utility model relates to an explosion-proof dust pelletizing system adopts multiple explosion-proof and explosion suppression measure, and the possibility with the explosion falls to minimum, even the explosion takes place also can carry out effectual protection to personnel and equipment, avoids causing the emergence of huge economic loss and major incident.
