Description
Technical field
The present invention relates to a kind of mineral hot furnace coal gas cooling device, particularly to a kind of automatic oil removing of mineral hot furnace coal gas except the cooling device of water, be mainly used in the coal gas cooling of iron alloy electric furnace and chemical industry furnace of calcium carbide.
Background technology
Mineral hot furnace is typical high energy consumption, high pollution industry.According to the industrial policy of China, turning down greatly, the sector just maximizes towards the type of furnace, the development of the smelting process of totally-enclosed, and gas purification problem can not be avoided.The current big-and-middle-sized mineral hot furnace coal gas commonly used wet scrubbing purification of China and recovery process, negative pressure operation, water is seriously polluted, and energy consumption is high, seriously corroded, and therefore, it is following mine heat furnace smelting and the developing direction of green technology that coal gas dry-method purifies technique.But, coal gas dry-method purifies technique and runs into new technical barrier, after i.e. using coal gas dry-method to purify technique, gas temperature reaches more than 100 DEG C, cannot directly enter gas chamber storage, about 60 DEG C storages need to be cooled to and just meet safety requirements, but in coal gas cooling procedure, moisture and tar in coal gas can separate out in a large number, the properly functioning of downstream gas fan can be affected as removed not in time, and have a strong impact on the heat transfer effect of cooler, therefore, research and develop a kind of automatic oil removing of mineral hot furnace coal gas except the cooling device of water and become the task of top priority.
Summary of the invention
It is an object of the invention to for the technical problem proposed in background technology, it is provided that a kind of automatic oil removing of mineral hot furnace coal gas is except the cooling device of water.
The technical solution of the present invention is: a kind of automatic oil removing of mineral hot furnace coal gas is except the cooling device of water, including air inlet loudspeaker, cooling tube, housing, escape pipe, cone bucket, exhaust stack, water sealing (sealing water) pipe, flashback tank, overflow pipe, draining valve；Described housing upper taps into air horn, and lower housing portion picks out tracheae, and housing bottom connects cone bucket, and enclosure interior arranges cooling tube；Water receiving tube sealing bottom cone bucket, water sealing (sealing water) pipe inserts in flashback tank, and flashback tank top connects exhaust stack, and flashback tank sidepiece connects overflow pipe, and run in bottom flashback tank fuel tap；Coal gas upper entering and lower leaving, cools down water bottom in and top out, countercurrent heat exchange.
Further, described cooling tube is snakelike metal tube, and described snakelike metal tube is light pipe, or finned tube.
Further, many groups of described cooling tube layout, parallel running.
This device has coal gas cooling, water seal for coal gas, automatic oil draining draining and venting of dust explosion several functions simultaneously, i.e. while coal gas cooling, tar and water that wash rice goes out are collected in the flashback tank of bottom by gravity, are automatically drained out continuously by overflow pipe, and form water seal partition in water sealing (sealing water) pipe；Once coal gas explodes, can be from flashback tank top exhaust stack venting of dust explosion；Each parts form integrated apparatus.
The operation principle of this device is: coal gas of high temperature enters air horn from top, flow through spiral coil cooling tube to lower the temperature, coal gas after cooling is discharged by discharge pipe, water and tar that in cooling procedure, wash rice goes out are pooled to flashback tank under gravity and form water seal, playing the effect of isolation air, solidifying water and tar are automatically drained out through overflow pipe；If it occur that gas explosion, the exhaust stack pressure release of flashback tank top, protection device can be passed through.
The invention has the beneficial effects as follows: be provided simultaneously with coal gas cooling, water seal for coal gas, automatic oil draining draining and venting of dust explosion several functions, and each parts form integrated apparatus, have good cooling results, compact conformation, easy to maintenance, take up an area less, the feature such as reduced investment, it is adaptable to coal gas enters the advanced treating before cabinet.
