2results about How to "Lower outlet temperature" patented technology

This invention discloses a high-temperature molten slag granulation system coupled with cyclone heat exchange and water mist, including a granulation chamber, a high-temperature molten slag transition device disposed at the top of the granulation chamber, a granulation disc disposed inside the granulation chamber and below the high-temperature molten slag transition device, and a transmission shaft and motor for driving the rotation of the granulation disc. A slag outlet is provided at the bottom of the granulation chamber, and multiple spray nozzles are evenly arranged circumferentially on the upper part of the inner side wall of the granulation chamber. At least four tangential high-pressure air inlets are provided circumferentially below the spray nozzles on the side wall of the granulation chamber, each high-pressure air inlet being connected to a high-pressure blower. An arc-shaped guide baffle is provided on the inner side of each high-pressure air inlet. The system of this invention has a compact structure and no additional moving parts. It can adapt to different working conditions such as blast furnace slag and steel slag by only adjusting the air pressure and water volume, and has broad industrial application value.

The utility model relates to the technical field of ozone tail gas destructors, and discloses an explosion-proof ozone tail gas destructor which comprises a machine shell, the machine shell is of a rectangular box body type structure, and the inner wall of the machine shell is provided with a processing cavity and an installation cavity through a partition plate. An explosion venting sheet, a gas heat exchanger, a catalytic converter and an electric heating pipe are sequentially arranged in the treatment cavity of the machine shell from top to bottom, and a gas inlet pipe is embedded in the back face of the machine shell. According to the explosion-proof ozone tail gas destructor, ozone tail gas enters equipment through a gas inlet pipe, sequentially flows through a gas heat exchanger, a conveying pipe, an electric heating pipe, a catalytic converter and a gas heat exchanger, is finally extracted by an axial flow fan and is discharged into the atmosphere, and the ozone tail gas is treated by adopting the principles of heating decomposition and catalytic decomposition in the whole scheme, the gas heat exchanger is arranged at the gas inlet end and can exchange heat with the heated tail gas, so that the gas inlet temperature is increased, the load of the electric heating pipe is reduced, the ozonolysis efficiency is improved, and the energy consumption is reduced.
