Pressure-equalizing bleeding device for ejecting furnace-top tank gas by high pressure gas

Abstract

The invention discloses a pressure-equalizing bleeding device for ejecting furnace-top tank gas by high pressure gas. The pressure-equalizing bleeding device comprises a pressure-equalizing bleeding pipeline, a pressure-equalizing bleeding valve, a primary pressure-equalizing valve, a secondary pressure-equalizing valve, a cyclone cinder valve, a cyclone dust collector, a bag-type dust collector, a gravitational dust collector and a clean gas network. The pressure-equalizing bleeding device further comprises an ejector comprising two inlets and an outlet. A forced recovery valve and a working gas valve are respectively disposed on a pipeline connected with the ejecting gas inlet. A check valve is disposed on an outlet pipeline of the ejector. The ejector is further provided with a bypass pipeline, and a natural recovery valve is disposed on the bypass pipeline. When pressure-equalized gas bleeds from a tank, the pressure-equalized gas is recovered to the clean gas network through devices such as the bag-type dust collector and the ejector. Therefore, environmental pollution and resource waste due to direct entry of the pressure-equalized gas in atmosphere is avoided.

AI Technical Summary

Benefits of technology

This patented device helps reduce harmful emissions from industrial processes that use compressed gases like air or nitrogen for various purposes. It uses an apparatus called bagsfilter/ejectors to return pressurised materials back to their source without causing damage on surrounding areas due to leaks during transportation. Additionally, this system has lower costs compared with previous systems because it only requires one piece of equipment instead of multiple pieces connected together at once.

Problems solved by technology

This patented technical problem addressed in this patents relates to reducing greenhouse gases from blast production processes while minimizing harmful exhaust emissions generated when unbalanced fluctuations occur due to changes made over time or other factors such as changing atmospheres. Current methods involve adding water mist to control particulate matter levels in the materials used in blasts making up the charge. However, these techniques are limited because they result in significant amounts of wasted chemical products being introduced into the world' s oceans with negative impact on both ecosystems and human health concerns.
