Description
Technical field:
The present invention relates to steelmaking equipment technical field, more particularly to a kind of compressed air oil removing de-watering apparatus.
Background technology:
, it is necessary to be passed through compressed air into the molten iron of melting during steel-making, removed by the oxygen in compressed air in molten iron
Unnecessary carbon.Because air contains vapor in itself, and supercharging equipment needs to use lubricating oil, fat etc., therefore compression is empty
It is unavoidable containing a large amount of vapor and amount of grease in gas, molten iron is such as passed directly into, grease can be empty with compression at high temperature
Oxygen in gas reacts rapidly, causes blast, and influence molten iron level is stable, and the accident of splashing is caused when serious;Water also can be in high temperature
Under be decomposed to form after hydrogen and oxygen, hydrogen emersion molten iron the problems such as causing to burn with anger, explode, influence production safety.
Existing compressed air removes water waste-oil scavenger, generally coagulates the oily mode of water-setting using low temperature fin after simple refrigeration,
Because the contact area of compressed air and fin is limited, water removal deoiling effect is unstable.

The cleaning frequency of filter cylinder, while preventing the impurity such as the dust in compressed air pollution obstruction lamination filter cylinder.
Further, the design also include blast pipe filter ring, blast pipe filter ring be ring pipe, installed in upper spacer with
It is circular layout between lower clapboard, along shell body inwall, blast pipe filter ring is vented with there are multiple exhaust branch pipes to connect between heat-preservation cylinder
Active carbon filter core is filled with pipe filter ring, the iron powder not adsorbed on a small quantity by spindle magnetic roller is filtered out by blast pipe filter ring, prevented
It is passed through molten iron influence product component with compressed air.
It is preferred that, dispenser is made up of middle pipe, power transmission shaft and spreading cone, and middle pipe stretches into guarantor by top cover labyrinth central openings
Warm cylinder, dispenses cone and is fastened on middle ttom of pipe end, dispenses cone upper end and is connected with power transmission shaft, heat-preservation cylinder inwall inwardly swells at spreading cone
Shape, makes the throat that area of space formation is collected in the heat-preservation cylinder, power transmission shaft operationally drives spreading cone to rotate, by low temperature iron powder
Outwards spread out, after the throat formed swelled from heat-preservation cylinder inwall constrained into centralized, pass twice through compression air flow channel, enter one
Step improves the flocculating result of moisture.
The present invention coagulates the operation principle of water by lamination oil removing and low temperature iron powder, effectively increases compressed air oil removing water removal
Effect, makes the production operation security for being passed through compressed air processing step during steel-making get a promotion.
