Method and device for cooling machine cabinet

The invention provides a method for cooling a machine cabinet, which comprises the following steps: injecting cold air into a machine cabinet from the lower part of the machine cabinet; delivering the cold air bottom-up in the machine cabinet to cool heating components in the machine cabinet; discharging hot air with high temperature after heat exchange from the upper part of the machine cabinet; cooling the discharged hot air; and injecting the cold air generated through cooling the hot air into the machine cabinet from the lower part of the machine cabinet, and cyclically cooling the machine cabinet. The invention also provides a device for cooling the machine cabinet, which comprises a machine cabinet which is provided with a hot air outlet on the upper part and a cold air inlet on the lower part, a blowing unit which is used for delivering the cold air injected from the cold air inlet bottom-up from the lower part of the machine cabinet, and a liquid cooling unit which is used for cooling the hot air discharged from the hot air outlet and injecting the cold air into the machine cabinet from the cold air inlet. The invention adopts the features that cold air subsidises and hot air rises based on the water cooling mode, and organically combines vertical cooling and water cooling, thereby effectively improving the cooling effect.

Process nozzle and system for gasifying water coal slurry and application thereof

The invention provides a process nozzle and a system for gasifying water coal slurry. The process nozzle comprises a first oxygen channel, a water coal slurry channel, a second oxygen channel, a first cooling water jacket and a cooling water coil, wherein the first oxygen channel comprises a first oxygen channel inlet and a first oxygen channel outlet; the water coal slurry channel comprises at least one water coal slurry channel inlet and a water coal slurry channel outlet; the second oxygen channel comprises a second oxygen channel inlet and a second oxygen channel outlet; the first cooling water jacket comprises a first cooling water jacket inlet and a first cooling water jacket outlet; and the cooling water coil comprises a cooling water coil inlet and a cooling water coil outlet. The process nozzle is characterized in that: the first oxygen channel is positioned at the central position of the process nozzle; the water coal slurry channel is positioned between the first oxygen channel and the second oxygen channel and surrounds the periphery of the first oxygen channel; and the second oxygen channel surrounds the periphery of the water coal slurry channel. The process nozzle reduces the length of combustion flame more effectively, reduces the ablation of flame on a refractory brick, promotes the mixing and atomization of water coal slurry and oxygen and improves gasification efficiency.

Fire extinguishing by explosive pulverisation of projectile based frozen gases and compacted solid extinguishing agents

This invention relates to a forest, terrain and urban fire fighting device and method, and more particularly, to a fire extinguishing system and method offering reduced risk of fire spread and safety of firemen. This extinguishing device consists of an encapsulated cryogenic projectile with a payload of solidified and frozen mixture of carbon dioxide, nitrogen, combination of gases and compacted solid extinguishing agents. These strategically located and cryogenically stored devices are launched at the outbreak of fire, aerially or terrestrially over a blaze. An embedded explosive charge is detonated at a predetermined and optimum height causing the solidified gases/compacted solid extinguishing agents to be dispersed instantaneously and forcefully over targeted and specified areas. The release of high pressure, low temperature oxygen exclusion gases penetrate the fire from above, chills the substrate and extinguishes the fire. As carbon dioxide is heavier than air it hangs as a cloud over the extinguished substratum effectively preventing reignition. Fly ash, fine quarry dust or any solid or semisolid extinguishing agent can also be made to disperse under force over the fires in the same mode which cuts off the oxygen supply to the burning substrates. By effectively checking and cooling the fuel complex substrate by successive pulverizations as needed this invention enables a low cost, scalable, and effective urban, terrain and forest fire intervention/extinguishing process.
