Abstract
The utility model discloses a modified ou ye stove oxygen wind gap device, including the air compressor machine, the air outlet of air compressor machine passes through the compressed air pipe way and is connecting a circulating line, install pressure gauge on the compressed air pipe way in proper order, the trip valve, the flow measurement valve, cut valve and flow control valve soon for two, the utility model provides a check valve, exit end that compressed air pipe said is along the tangential direction of circulating line rather than being linked together, an oxygen hose passes from the circulating line, equipartition fixture sliding seat four intake pipe on the tangential direction pipe wall of this oxygen hose, four intake pipe are linked together with the internal perisporium of circulating line. After compressed air passes through the non return device, get into the oxygen house steward through compressed air pipeline and circulating line device, compressed air pass through that the circulating line device can be even with the oxygen mixing, can reduce oxygen consumption, practice thrift and smelt the cost.
Description
Technical field
This utility model relates to the Ou Ye stove oxygen wind gap device of a kind of improvement。
Background technology
Metallurgical Ou Ye stove mainly uses oxygen as combustion-supporting gas, coke or block burning of coal mainly rely on oxygen to enter in gasification furnace stove from air port, generate reducing gas after burning and produce heat, the technique of air port oxygen uses condition to be entered the oxygen of gasification furnace by air port (oxygen mouth), after this road oxygen enters from pylon, have to pass through valve control system and system of stopping leakage in the roof, finally enter oxygen endless tube 28 oxygen mouths of distribution。If unilaterally using out pure oxygen to send in stove, not only oxygen consumption is big, and it is not enough to will result in coal gas amount in stove, furnace heat distribution is irregular, the problems such as furnace charge reduction heat is inadequate, the theoretical temperature combustion before air port is higher simultaneously, and the working of a furnace and ferrum mouth will be caused not normal, air port breakage aggravation, gasification furnace normally produces and is limited。
Summary of the invention
The purpose of this utility model is in that to provide the Ou Ye stove oxygen wind gap device of a kind of improvement, it is possible to reduce oxygen consumption, saves smelting cost。
This utility model solves its technical problem and be the technical scheme is that the Ou Ye stove oxygen wind gap device of a kind of improvement, including air compressor machine, the air outlet of air compressor machine is connected to a circulating line by compressed air piping, compressed air piping is installed with pressure gauge successively, stop valve, flow rate measurement valve, cut valve and flow control valve soon for two, check-valves, the port of export of compressed air piping is coupled logical along the tangential direction of circulating line, a piece oxygen hose passes from circulating line, on the tangential direction tube wall of this oxygen hose, uniform interval is connected to four air inlet pipe, four air inlet pipe are connected with the internal perisporium of circulating line。
Technical characterstic of the present utility model is for utilizing compressed-air actuated production more simple than nitrogen and cost this feature low, utilize the compression air air compressor machine of air compressor plant, pass through pipeline, the construction and installation of pressure tester, shearing device and safety attachment and interlock, complete the function of this complete equipment。Compression air is delivered to pylon through compressed air piping after being pressurizeed by the compressor of air compression station, opens shearing device, and this device must possess reliable cut-out and reliably open dual-use function。Compression air, after the pressure that pressure detecting reaches working condition requirement, opens quick cutting device, and this quick cutting device can reliably fast shut-off and quickly open dual-use function。Owing to compressed-air actuated pressure is more than the oxygen pressure in endless tube, check valve apparatus is automatically opened up therefrom by pressure differential, this device is can be automatically switched off after compressed air pressure deteriorates to less than endless tube oxygen pressure, it is prevented that oxygen alters a kind of safety device to compressed air piping。Compression air is by, after check device, entering oxygen house steward by compressed air piping and circulating line device, and compression air can be blended with oxygen uniformly by circulating line device, it is possible to reduces oxygen consumption, saves smelting cost。
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is described in further detail。
Fig. 1 is attachment structure schematic diagram of the present utility model。
Detailed description of the invention
A kind of Ou Ye stove oxygen wind gap device of improvement, as shown in Figure 1, including air compressor machine 1, the air outlet of air compressor machine 1 is connected to a circulating line 12 by compressed air piping 9, compressed air piping 9 is installed with pressure gauge 2 successively, stop valve 3, flow rate measurement valve 4, cut valve 5 soon for two, 6 and flow control valve 7, check-valves 8, the port of export 10 of compressed air piping is coupled logical along the tangential direction of circulating line 12, a piece oxygen hose 11 passes from circulating line 12, on the tangential direction tube wall of this oxygen hose 11, uniform interval is connected to four air inlet pipe, four air inlet pipe are connected with the internal perisporium of circulating line 12。
