Description

미분기의 죽탄제거용 고압분사기{High pressured water sporay for removing coal gruel of pulverizer}High pressured water sporay for removing coal gruel of pulverizer

본 발명은 유연탄을 사용하는 화력발전소의 미분기에 관한 것으로, 더욱 상세하게는 미분기 내벽에 부착되게 되는 죽탄 제거가 간편하게 하여 작업 편이성을 제공할 수 있게 한 화력발전소 미분기의 죽탄제거용 고압분사기에 관한 것이다.The present invention relates to a pulverizer of a coal-fired power plant using bituminous coal, and more particularly, to a high-pressure jet sprayer for pulverizing coal dust of a coal-fired power plant, which makes it easier to remove the bamboo charcoal attached to the inner wall of the pulverizer. .

잘 알려진바와 같이 화력발전소에서는 유연탄을 사용하여 필요한 전력을 얻도록 되어 있다.As is well known, coal-fired power plants use bituminous coal to get the power they need.

하지만 화력발전소의 경우 연료로 이용되는 유연탄 특히 강우량이 상대적으로 많거나 지속적인 우천시에는 죽탄의 생성으로 미분기의 중앙파이프(CENTER PIPE) 내벽에 달라붙게 되고, 이처럼 미분기에 죽탄이 부착 및 고착되게 되는 경우 미분기가 막히는 현상(PLUGGING)이 종종 발생하게 되어 이를 제거하도록 되어 있다.However, in the case of thermal power plants, bituminous coal used as fuel, especially in rainy weather or in case of rainy weather, is produced when bamboo coal is attached to the inner wall of CENTER PIPE due to the formation of bamboo charcoal. Plugging often occurs and is intended to eliminate it.

따라서 미분기에 생성되는 죽탄을 모두 제거하지 않으면 미분기의 운전불가로 인해 전력을 안정되게 공급하지 못하는 원인이 되었다.Therefore, if all the bamboo charcoal generated in the mill is not removed, the operation of the mill will not be able to supply power stably.

그리하여 종래에는 죽탄 제거를 위해 미분기의 맨홀을 통해 중앙 파이프의 하부측에서 소방호스를 이용하여 정비원이 직접 물을 분사시키는 방법을 통해 죽탄을 제거하고 있다.Thus, conventionally, bamboo charcoal is removed through a method of directly injecting water using a fire hose at the lower side of the central pipe through the manhole of the pulverizer to remove bamboo charcoal.

이처럼 종래에는 단순한 형태로 된 소방호스와 정비원에 의한 인위적인 방법 즉, 수작업을 통해 미분기의 죽탄 제거하고 있어 이들 작업시 죽탄 낙하에 의한 안전사고의 위험성이 상존 하였다.As such, in the conventional art, the fire hose and the maintenance method by the maintenance person, that is, by removing the bamboo charcoal in the powder by manual labor, have the risk of safety accident due to the bamboo charcoal falling during these operations.

또한, 석탄 공급장치(Coal Feeder)의 상부에서 물을 분사하게 되는 경우 주변을 오염시키게 되는 문제점이 있었다.In addition, when water is injected from the upper portion of the coal feeder (Coal Feeder) there was a problem that will pollute the surroundings.

그리고 작업자의 손이 미치지 아니하거나 구석진 곳은 별도의 보조장치(길이가 긴 파이프 또는 "ㄱ" 환봉)에 소방호스를 고정하게 되나 이 경우 작업 준비시간 및 본 작업시간이 많이 소요되는 문제점이 있었다.And the worker's hand does not reach or the corner where the fire hose is fixed to a separate auxiliary device (long length pipe or "a" round bar), but in this case there was a problem that the work preparation time and this work time takes a lot.

상기한 종래의 문제점은 미분기에 생성되는 죽탄제거 작업이 정비원이 직접 소방호스를 이용하여 물을 분사하게 됨으로써 그에 따른 안전사고의 위험성 및 정비시간 등이 많이 소요되는데서 비롯되었던 것이다.The conventional problem is that the bamboo charcoal removal work generated in the differentiator originates from the fact that the maintenance worker directly sprays water using the fire hose, resulting in high risk of safety accidents and maintenance time.

이에 본 발명에서는 상기한 바와 같은 종래의 문제점을 해소하기 위해서, 죽탄 제거작업이 미분기 내부가 아닌 외부에서 보다 간편하고 신속하게 이루어질 수 있게 하여 정비 작업중에 발생할 수 있는 각종 안전사고 예방 및 정비시간 등을 단축시킴에 있는 것이다.Accordingly, in the present invention, in order to solve the conventional problems as described above, the bamboo charcoal removal operation can be made more easily and quickly in the outside, not inside the mill, to prevent various safety accidents and maintenance time that can occur during maintenance work. It is in shortening.

호스(2)가 연결되는 급수구(12)에는 본체(1)에 공급되는 유량과 압력 등을 제어할 수 있도록 된 차단밸브(7)가 부설되어 있다.The water inlet 12 to which the hose 2 is connected is provided with a shutoff valve 7 which can control the flow rate and the pressure supplied to the main body 1.

이와 같이 구성 결합된 본 발명의 작동 관계 등을 보다 구체적으로 설명하면 다음과 같다.When described in more detail the operating relationship and the like of the present invention coupled to the configuration as follows.

미분기의 중앙 파이프에 죽탄이 생성되어 이를 제거하고자 할 때는 먼저 본체(1)의 일측단 즉, 고압노즐(3)이 부설되는 절곡된 부위를 미분기의 맨홀을 통해 그 내측으로 일정한 길이만큼 장입되게 밀어 넣는다.When bamboo charcoal is formed in the central pipe of the differentiator and is to be removed, first, one end of the main body 1, that is, the bent portion where the high-pressure nozzle 3 is placed, is pushed to the inside through the differentiation manhole by a predetermined length. Put it in.

그런 다음 지지부재(4)의 안치대(5)를 맨홀의 턱에 고정되게 고정구를 이용하여 고정하게 되면 맨홀에 삽입되는 본체(1)가 좌,우로 요동하는 일이 없게 된다.Then, when the fixing stand 5 of the support member 4 is fixed to the jaw of the manhole by using a fastener, the main body 1 inserted into the manhole does not swing left and right.

이 상태에서 본체(1)에 부설되는 차단밸브(7)를 개방하여 본체(1)로 공급되는 유량과 압력을 조절하게 되면 본체(1)의 내측으로 유입되는 물은 그 선단에 고정되는 고압노즐(3)을 통해 고압의 형태로 분사되어지며 미분기의 중앙파이프에 생성된 죽판을 모두 제거할 수 있게 된다.In this state, when the shutoff valve 7 attached to the main body 1 is opened to adjust the flow rate and the pressure supplied to the main body 1, the water flowing into the main body 1 is fixed to the tip of the high pressure nozzle. It is sprayed in the form of high pressure through (3), and it is possible to remove all the bamboo plate formed in the central pipe of the grinding machine.

이때 본체(1)는 지지부재(4)에 지지된 상태에서 각각의 가이드 홀(66)과 홀더(6) 및 축핀(54)에 의해 본체(1)를 전,후방향은 물론 상,하,좌,우 방향으로도 자유롭게 움직이도록 구성되어 있어 작업자는 힘들이지 아니하고서도 죽탄 제거작업을 수행할 수 있는 것이다.At this time, the main body 1 is supported by the support member 4, each of the guide hole 66, the holder 6 and the shaft pin 54, the front and rear, as well as up, down, It is configured to move freely in the left and right directions, so that the worker can perform the bamboo charcoal removal without effort.

이상에서 설명한 바와 같이 본 발명은 미분기의 중앙 파이프에 고착되는 죽탄의 제거작업이 기기의 외부에서 간단한 기구장치로 구성된 고압분사기의 고압노즐을 전,후방향은 물론 좌,우,상,하 방향으로 이동시키면서 죽탄에 분사하게 되면 죽탄 제거작업이 간편하고 신속하게 이루어질 수 있을 뿐만 아니라, 정비 소요시간 단축에 의한 돌발사고 신속한 대처가 가능하여 고객 신뢰도 또한 크게 향상되는 이점이 있게 된다.As described above, in the present invention, the high pressure nozzle of the high-pressure injector composed of a simple mechanism is removed from the outside of the machine to remove the bamboo charcoal stuck to the central pipe of the grinding machine in the left, right, up and down directions as well as in the front and rear directions. When spraying bamboo charcoal while moving, not only can the bamboo charcoal removal work be done easily and quickly, but also the sudden response due to the shortened maintenance time can be promptly dealt with, which greatly improves customer reliability.

따라서 종래와 같이 정비원이 직접 소방호스를 이용하여 물을 분사시키는데 다른 제반 문제점 등이 모두 일소되게 되는 작용 효과가 있는 것으로 전국 유연탄 발전소의 모든 미분기에 적용하게 아주 유용하게 사용되어질 수 있게 된다.Therefore, as a conventional technician has the effect that all the other problems, such as all the problems to be directly sprayed by the fire hose directly fired to be applied to all the different mills of bituminous coal power plants nationwide can be very useful.
