After that, if a wet type dust collector 3 using K such as spray water is installed, the K gas temperature will be lowered to about 60°C and the dust in the gas will be removed.
従って、ガスの顕熱は大部分がスプレー水に持ち去られ
、有効に熱回釈することは出来なかったそれは次の理由
によるためで゛ある。Therefore, most of the sensible heat of the gas was carried away by the spray water, and the heat could not be effectively converted for the following reasons.

It is a well-known fact that dust containing as the main component is present at a concentration of about 12 Of/N-. In that round,
When a convection heat exchanger, which is effective in recovering heat from medium-low temperature gas, is used, the dust accumulates in the heat exchanger tubes, interfering with normal use. Therefore, it is difficult to use a convection type heat exchanger.
本発明者らは以上の問題点を解決するために対流式の熱

式による集塵装置4に導く。The converter gas containing 00 as the main component is generated from the mouth of the converter 1, burns for 11 seconds, and reaches a temperature of about 1500°C. The sensible heat of the gas is recovered from the nine radiant heat exchanger tK installed at the top of the converter.
'j! After the temperature reaches 1,00°C to 1,000°C, the dust is introduced into a dry type dust collector 4.
乾式による集塵装置の設置理−は次の様であも1つには
対流式の熱交換器の便用に問題ない様にダストを除去す
るためである。The installation procedure for the dry type dust collector is as follows.One of the reasons is to remove dust so that there is no problem in using the convection type heat exchanger.
19には湿式による集塵装置は転炉ガスの温度を低下せ
しめるために顕熱を有効に利用で11′&へよって乾式
を使用する。In 19, a wet type dust collector effectively utilizes sensible heat to lower the temperature of the converter gas, and in 11' and 11', a dry type dust collector is used.
1つKFi湿式の集塵装置であると集塵装置によ〉捕集
しきれなかつえ飛散微小ダストが湿潤する丸め、後の対
流式O熱交換SSで増積し易い。If the KFi wet type dust collector is used, the scattered microscopic dust that cannot be completely collected by the dust collector becomes wet and is likely to accumulate during the subsequent convection type O heat exchange SS.
以上の層内によ〉設置す為集塵機は乾式であらねばなら
ない。Since the dust collector is installed within the above layers, it must be a dry type.
図には衝央反転式による集塵装置を示し九がナイターン
による方式もより有効でTo為。The figure shows a dust collector using the center-inversion type, and the number 9 indicates that the night-turn type is also more effective.

収を行う。The collected dust is discharged outside the system by a water seal type dust discharge device SK.Thereafter, most of the dust in the gas is removed and the dust is 111 degrees 50yN1.
After the temperature becomes less than 1/2, the heat is introduced into a convection heat exchanger 6 for heat recovery.
以上の装置によ妙転炉ずスのJII熱の大半を効率よく
回収する。The above device efficiently recovers most of the JII heat from the converter.
顕熱を十分に回収され温度が300℃以下になった2転
炉廃ガスは環境汚染ならびに燃料としての使用上問題な
き様にダスト談縦を5(kd/ N−以下にするために
2次集塵装置7へと導かれる。The waste gas from the second converter reactor, whose temperature has dropped to below 300°C after sufficient sensible heat recovery, is sent to the secondary converter in order to reduce the dust content to below 5 (kd/N-) to avoid environmental pollution and use as a fuel. The dust is guided to the dust collector 7.
本方弐による装置をiso≠−の転炉に設置しての効果

較し3〜4倍の熱量である。Regarding the amount of heat recovery, is it 300t from 1soo'c? , it is possible to recover the sensible heat of the converter gas up to 1000 kW), which results in a calorific value of approximately 4 x 1 v- of molten steel. This is 3 to 4 times the amount of heat compared to the conventional method.
