Description
In order to adapt to the needs of aspects such as modern blast furnace cloth control and high top pressure operation, non-bell furnace top charging equipment is used widely gradually, and a vitals of nuclear equipment is distributor transmission case and transmission rig (seeing USPat. № 3814403 and 3880302) thereof.Its principal feature is to utilize epicyclic transmission mechanism to make distributor chute both around blast furnace medullary ray rotation, the own inclination angle of change at any time again, thus control provides means preferably to blast furnace material distribution.But, only resolve the cooling of transmission case and prevent that the furnace high-temperature raw gas from entering the works better of transmission rig in the ability guard box because transmission case is to place the equipment that is subjected to the invasion and attack of furnace high-temperature raw gas on the top cone.Existing technology is continuously to lead to cold air (nitrogen after the pressurization or purified gas) in transmission case, and the cold air after using through transmission case constantly enters in the stove again, and the furnace high-temperature raw gas of resisting enters in the transmission case.
Practice shows, but though in transmission case, constantly lead to normal temperature and dustless Working environment in the cold air guard box, but for cooling gas continuously except the press that will be equipped with at least two about 500KW and factory building thereof and relevant operating device, still need and set up by pressurization machine room (general with oxyen manutactory together), want millions of first investments of polyvoltine for this reason to the relevant facility of the pipeline of iron work blast furnace furnace roof with other.On the other hand,, make annual production maintenance costs also will increase nearly 1,000,000 yuan spending, influence the economic benefit of this new technology because daily cold air consumption is big.Nitrogen enters the calorific value that will reduce blast furnace gas in the stove, also is a shortcoming.
In order to overcome the shortcoming of above-mentioned air cooling transmission case, the present invention proposes a kind of water-cooled water-sealed formula distributor of not wanting any external cold air.The characteristics of this distributor are to adopt by coal gas in the stove from the water-cooled transmission case and the outside draining of U-shaped pipe hydrolock water exhaust system thereof of all pressing.The water-cooled transmission case is in the moving housing of a side in the stove and quiet housing and all is provided with heat insulation and water-cooled and anti-sealing and enters facility in the stove, and, furnace gas is provided with the dust separating designated lane of water for freeing in and out transmission case, make the furnace gas that enters in the case promptly pass through water cooling and water dedusting in the ingress, and stay the environment that forms the cold conditions pure qi (oxygen) in the case for a long time, simultaneously the pure qi (oxygen) in the case all the time with stove in the high temperature raw gas form the dynamic pressure balance.Transmission rig in the transmission case removes moving housing and passes moving housing and enters part in the stove and need water cooling and anti-sealing enter in the stove, and other all parts are in the environment that the cold conditions pure qi (oxygen) surrounds, and therefore also just do not need water-cooled.
The U-shaped pipe hydrolock water exhaust system of transmission case is to utilize the shaft height to rise to the formed U-shaped pipe draining up to tens of meters in shaft top again after furnace roof causes ground, it is continuously draining but also can prevent that the coal gas of any pressure in the stove from leaking from water exhaust system not only, therefore guarantees carrying out smoothly of blast furnace high top pressure operation.
