Abstract: A negative-pressure smoke-guiding fireproof building structure includes at least one vertical smoke discharge flue arranged in the building and in fluid communication with a transverse smoke discharge flue arranged in upper space of each floor. At least one natural air inlet window having a door and at least one smoke-gas discharge window having a door are arranged in a wall of each independent room off each floor. The doors normally seal the windows in a closed position and are capable of automatically opening at a fire hazard. The smoke-gas discharge window is in fluid communication with the transverse smoke discharge flue. With a simple structure, the building structure effectively prevents fire spreading to peripheral adjacent rooms when one room in the building catches fire, so as to prevent a larger fire hazard.

Abstract: A negative-pressure smoke-guiding fireproof building structure includes at least one vertical smoke discharge flue (1) arranged in the building and a transverse smoke discharge flue (2) arranged in upper space of each floor. The vertical smoke discharge flue (1) is in fluid communication with the transverse smoke discharge flue (2). At least one natural air inlet window (4) and at least one smoke-gas discharge window (5) are arranged in a wall (3-1) of each independent room (3) of each floor. The natural air inlet window (4) consists of an air inlet window (4-1), an air inlet window door (4-2) capable of sealing the air inlet window (4-1) in the normal state, and an air inlet window door opening mechanism capable of automatically opening the air inlet window (4-1) at a fire hazard.

Abstract: The present invention relates to apparatus for incinerating dangerous waste, and in particular, apparatus for incinerating dangerous waste in various forms. It comprises a continuous feeding device, an incineration furnace, a flue gas quenching device, a flue gas treating device, and an online monitoring system. The continuous feeding device includes device for feeding paste, powder, and solid device. The quenching device is connected to a steam boiler and a thermal oil tank, thus achieving comprehensive utilization of the thermal energy generated during incineration of the waste. Apparatus for incinerating dangerous waste according to the present invention enables sufficient combustion of the waste, recycling of the metal oxides or noble metals from the combustion flue gas and/or sinters and/or furnace ashes, effective elimination of the concurrent degradation and re-forming of dioxins.
