본 발명은 먼저 도 1에서 도시된 바와같이 각종 산업현장에서 발생하여 연도(10)로 배출되는 폐가스를 폐가스 흡입펌프(20)를 통하여 흡입하고, 이 흡입된 폐가스는 분진포집장치(30)로 보내져 흡입된 폐가스중에 함유된 분진을 분진포집장치(30)에서 필터링 되도록 하였다.First, the present invention sucks the waste gas generated in various industrial sites and discharged to the flue 10 through the waste gas suction pump 20 as shown in FIG. 1, and the sucked waste gas is sent to the dust collecting device 30. Dust contained in the inhaled waste gas was filtered in the dust collecting device 30.

이와같이하여 폐가스중에 함유된 분진성분을 포집하고난 폐가스는 폐가스 공급장치(40)를 통하여 처리제 수용탱크(50)의 저부에 골고로 공급된다. 그후 공급된 폐가스는 처리제 수용탱크(50)의 저부에 설치된 폐가스 분산장치(60)를 통하여 처리제와 골고루 섞인다. 이와같이 된 폐가스와 처리제는 온도콘트롤 장치(70)를 통하여 처리제가 저온으로 유지됨으로 화학반응을 촉진시킨다.In this way, the waste gas which has collected the dust components contained in the waste gas is supplied to the bottom of the treatment agent accommodating tank 50 through the waste gas supply device 40. Thereafter, the supplied waste gas is evenly mixed with the treating agent through the waste gas dispersing device 60 installed at the bottom of the treating agent receiving tank 50. Thus, the waste gas and the treatment agent promote the chemical reaction by maintaining the treatment agent at a low temperature through the temperature control device 70.

따라서 상기 폐가스중에 함유된 유해가스는 처리제와 함께 중화처리되어 무해가스가 된다. 그후 처리제 수용탱크(50)내의 상부에 설치된 부유물처리장치(80)는 처리제의 상부에 떠있는 부유물을 포집한다.Therefore, the harmful gas contained in the waste gas is neutralized with the treatment agent to become a harmless gas. Thereafter, the float treatment apparatus 80 installed on the upper portion of the treatment agent accommodating tank 50 collects the float floating on the upper portion of the treatment agent.

따라서 배출구(51)로 배출되는 가스는 무해가스이다.Therefore, the gas discharged to the discharge port 51 is a harmless gas.

이와같은 구성으로 이루어지는 폐가스처리과정은 더욱 구체적으로 설명하면 다음과 같다.The waste gas treatment process having such a configuration will be described in more detail as follows.

본 발명은 도 1에서 도시된 바와같이 연도(10)의 상부에 덕트(21)를 설치하고 이 덕트(21)의 중앙부분에는 폐가스 흡입펌프(20)를 설치하여 이 폐가스 흡입펌프(20)로 연도(10)에서 나오는 폐가스를 흡입시킨다.In the present invention, as shown in FIG. 1, the duct 21 is installed on the top of the flue 10 and the waste gas suction pump 20 is installed at the center of the duct 21 to the waste gas suction pump 20. Inhaling the waste gas from the flue (10).

그후 상기 폐가스 흡입펌프(20)로 흡입된 폐가스는 덕트(21)를 통하여 폐가스 흡입펌프(20)의 후방덕트(21)상에 설치된 분진포집장치(30)로 폐가스중의 분진을 포집한다.Thereafter, the waste gas sucked into the waste gas suction pump 20 collects dust in the waste gas through a duct 21 through a dust collecting device 30 installed on the rear duct 21 of the waste gas suction pump 20.

그리고 분진이 포집된 폐가스는 폐가스공급장치(40)즉 다수의 관(41)들을 통하여 처리제(90)가 수용되어 있는 처리제 수용탱크(50)의 저부에 공급된다.The waste gas collected in the dust is supplied to the bottom of the treatment agent accommodating tank 50 in which the treatment agent 90 is accommodated through the waste gas supply device 40, that is, the plurality of pipes 41.

이와같이하여 공급된 폐가스는 폐가스분산장치(60)즉 다수의 구멍(62)이 형성된 분산판(61)을 통과하면서 폐가스가 골고루 분산되게 되는 것이다. 그후 분산된 폐가스는 처리제(90)와 섞이면서 온도콘트롤장치(70)에 의해 처리제(90)의 온도가 저온을 유지함으로 화학반응이 촉진된다.The waste gas thus supplied passes through the waste gas dispersing device 60, that is, the distribution plate 61 in which the plurality of holes 62 are formed, so that the waste gas is evenly distributed. Thereafter, the dispersed waste gas is mixed with the treatment agent 90 and the chemical reaction is promoted by maintaining the low temperature of the treatment agent 90 by the temperature controller 70.

이렇게하여 폐가스중에 함유된 유해가스가 처리제(90)와 화학반응을 하게 되면 상기 유해가스는 중화되어 무해가스가 된다. 한편 무해가스가 된 가스는 배출구(51)를 통하여 대기중으로 배출되고 처리제(90)의 상부에 떠있는 부유물은 부유물은 포집장치(80)에서 포집된다. 단 상기 처리제는 순수물에 수산화나트륨(NaoH)을 혼합한 화합물이며 폐가스중에 함유된 유해가스는 F,Cl, No, So, Co, H2S이다.In this way, when the harmful gas contained in the waste gas is chemically reacted with the treatment agent 90, the harmful gas is neutralized to become a harmless gas. On the other hand, the gas which has become harmless gas is discharged into the atmosphere through the discharge port 51, and the floating matter floating on the upper portion of the treatment agent 90 is collected in the collecting device 80. However, the treatment agent is a compound in which sodium hydroxide (NaoH) is mixed with pure water, and the harmful gases contained in the waste gas are F, Cl, No, So, Co, and H 2 S.

이의 화학반응을 설명하면 다음과 같다.The chemical reaction thereof is as follows.

NaOH + HF → NaF + H20 FNaOH + HF → NaF + H 2 0 F

NaOH + HCl → NaCl + H20 ClNaOH + HCl → NaCl + H 2 0 Cl

NaOH + HNO3→ Na2NO3+ H2O NOx NaOH + HNO 3 → Na 2 NO 3 + H 2 O NO x

2NaOH + H2SO4→ Na2SO4+ 2H20 SOx 2NaOH + H 2 SO 4 → Na 2 SO 4 + 2H 2 0 SO x

2NaOH + H2CO3→ Na2C03+ 2H20 COx 2NaOH + H 2 CO 3 → Na 2 C0 3 + 2H 2 0 CO x

2NaOH + H2S = Na2S + 2H2O H2S2NaOH + H 2 S = Na 2 S + 2H 2 OH 2 S

이상과 같은 본 발명은 각종산업현장에서 발생하는 폐가스중에 함유된 유해가스를 간단하고 완벽하게 처리하여 대기중으로 방출시킴으로서 사회문제화 되고있는 대기오염을 예방할수 있는 효과가 있다.The present invention as described above has an effect that can prevent the air pollution that is becoming a social problem by simply and completely treating the harmful gas contained in the waste gas generated in various industrial sites to release to the atmosphere.
