Description

장입차의 탄화실 배기장치{APPARATUS FOR EXHAUST GAS OF COKES OVEN IN CHARGING CAR}Carbon chamber exhaust system of charge vehicle {APPARATUS FOR EXHAUST GAS OF COKES OVEN IN CHARGING CAR}

본 발명은 탄화실에 석탄을 공급하는 장입차의 탄화실 배기장치에 관한 것으로, 보다 상세하게는 탄화실내에 석탄을 장입할 때 발생하는 가스와 분탄을 배기하는 장입차의 탄화실 배기장치에 관한 것이다.The present invention relates to a carbonization chamber exhaust system of a charging vehicle for supplying coal to a carbonization chamber, and more particularly, to a carbonization chamber exhaust system of a charging vehicle for exhausting gas and coal dust generated when charging coal into the carbonization chamber. will be.

일반적으로 코크스 오븐(Cokes oven)은 도 1에 도시된 바와 같이 사각형 구조를 갖추고 내부에 다수의 격벽(8)을 형성하여 다수개의 탄화실(1,2)을 갖추며, 각각의 탄화실(1,2) 상부에는 복수의 ,예컨대 4개의 장입구(3a,3b,3c,3d)들이 형성되어 있다. 또한, 탄화실(1,2)내에서 발생하는 코크스가스(cokes gas)를 외부로 배출시키는 상승관(4)이 탄화실(1,2)마다 각각 형성되고, 코크스 장입차(10)가 코크스 오븐의 상부를 왕복이동하면서 각각의 탄화실(1,2)에 석탄을 장입하도록 되어 있다.In general, a coke oven (Cokes oven) has a rectangular structure as shown in Figure 1 and forms a plurality of partitions 8 therein to have a plurality of carbonization chamber (1, 2), each carbonization chamber (1, 2) A plurality of, for example, four charging holes 3a, 3b, 3c and 3d are formed at the top. In addition, ascending pipes 4 for discharging cokes gas generated in the carbonization chambers 1 and 2 to the outside are formed for each carbonization chamber 1 and 2, respectively, and the coke charging vehicle 10 is coke. Coal is charged in each of the carbonization chambers 1 and 2 while reciprocating the upper part of the oven.

상기와 같이 코크스오븐의 탄화실(1)내로 석탄을 장입하는 과정에서 다량의 가스와 분탄이 탄화실 내부에서 발생하기 때문에 석탄을 비산시키지 않고 장입하기 위해서는 상기 발생가스와 분탄을 외부로 배출시켜야 한다.As described above, since a large amount of gas and coal are generated inside the carbonization chamber in the process of charging coal into the carbonization chamber 1 of the coke oven, the generated gas and the coal dust must be discharged to the outside in order to charge the coal without scattering. .

상기 상승관(4)을 통하여 가스와 분진을 배출시키나, 상승관(4)으로부터 멀리 떨어진 제3 장입구(3c) 및 제4 장입구(3d)에서 발생하는 가스와 분진은 제1,2장입구를 통해 유입되는 석탄 및 가스의 흐름에 막혀 장입중인 탄화실(1)의 상승관(4)을 통한 배출이 용이하지 않다.The gas and the dust are discharged through the riser 4, but the gas and the dust generated at the third and third charges 3c and 3d away from the riser 4 are discharged in the first and second pieces. It is not easy to discharge through the rising pipe 4 of the carbonization chamber 1 being charged because it is blocked by the flow of coal and gas flowing through the inlet.

따라서, 종래에는 도1에 도시된 바와 같이 제3 장입구(3c) 및 제4 장입구(3d)에서 발생하는 가스와 분진을 제3,4 피더콘(11c,11d)에 연결된 인접구 배기관(12)을 통하여 인접 탄화실(2)로 이송한 후 인접 탄화실의 상승관(7)을 통해 외부로 배출하도록 하였다.Therefore, conventionally, as shown in FIG. 1, the gas and dust generated at the third charging hole 3c and the fourth charging hole 3d are connected to the third and fourth feeder cones 11c and 11d. 12) was transferred to the adjacent carbonization chamber (2) and then discharged to the outside through the rising pipe (7) of the adjacent carbonization chamber.

도 2는 상기 피더콘(11)과 인접구 배기관(12)의 연결상태를 보여준다.2 shows a connection state between the feeder cone 11 and the adjacent mouth exhaust pipe 12.

그러나, 종래와 같은 인접로 배기장치에 의할 경우, 인접탄화실(2)은 코크스화가 진행중인 미건류상태에 있으므로 인접구 배기관(12)을 인접구에 연결시 인접구의 리드(6)를 개방하는 과정에서 공기가 유입되어 코크스의 품질에 나쁜 영향을 주고, 인접탄화실(2)내의 산소성분의 증가로 폭발의 위험이 있으며, 공기유입으로 인한 연소로 인접탄화실(2)내부의 국부과열로 인한 내화물의 손상으로 로체 수명저하의 원인이 되고 있다. 또한 탄화실가스의 유출로 인하여 대기환경 오염이 발생하는 문제점이 있다.However, in the case of the conventional furnace exhaust apparatus, the process of opening the lid 6 of the adjacent port when the adjacent carbon exhaust pipe 12 is connected to the adjacent port because the adjacent carbonization chamber 2 is in an undry state in which coking is in progress. Air is introduced from the air and adversely affect the quality of the coke, and there is a risk of explosion due to the increase of oxygen content in the adjacent carbonization chamber (2), and due to local overheating in the adjacent carbonization chamber (2) Damage to the refractory causes a reduction in furnace life. In addition, there is a problem that the pollution of the air environment due to the leakage of carbonization chamber gas.

상기와 같은 문제점을 해결하기 위하여, 본 발명은 인접로 배기장치를 사용하지 않고 장입 피더콘의 일측에 장착된 가스포집관을 이용하여 탄화실내에 발생하는 가스 및 분탄을 포집하여 배출함으로써 인접 탄화실로의 공기유입을 방지하여 탄화실 내화물 손상방지, 코크스 품질안정 및 가스와 분탄이 대기중으로 비산되어 발생하는 환경오염 문제점을 해결하는 장입차의 탄화실 배기장치를 제공하는데 그목적이 있다.In order to solve the above problems, the present invention collects and discharges the gas and the coal generated in the carbonization chamber to the adjacent carbonization chamber by using the gas collection pipe mounted on one side of the charging feeder cone without using an exhaust device adjacently. The purpose of the present invention is to provide a carbonization chamber exhaust system for charging vehicles to prevent the inflow of carbon dioxide to prevent refractory damage to the carbonization chamber, to stabilize the coke quality and to solve the environmental pollution caused by the scattering of gas and coal into the atmosphere.
