본 발명은 석회석을 가열 열분해하여 생석회를 제조하는 석회소성로에 관한 것으로, 보다 상세하게는 소성조업시 발생되는 더스트에 의해 순환가스가 선회실로 흡입되지 못하여 순환가스의 흐름이 원활하지 않게 됨으로써 하부버너의 연소공기 부족, 연소불량, 조로관리의 불안정 등을 유도하여 제품의 품위를 저하시키는 것을 방지할 수 있도록 한 석회소성로 순환가스 선회실의 누적 더스트 배출장치에 관한 것이다.The present invention relates to a calcining furnace for producing quicklime by heating and pyrolyzing limestone, and more particularly, because the circulating gas is not sucked into the swivel chamber by dust generated during the firing operation, so that the flow of the circulating gas is not smooth. The present invention relates to a cumulative dust discharge device of a calcination furnace circulating gas swirling chamber which can prevent deterioration of product quality by inducing combustion air shortage, poor combustion, unstable management of a furnace.

종래 베켄베치 타입의 석회소성로는 도 1 및 도 2의 도시와 같이, 장입호퍼(1)에서 운전 설정된 생산량에 따라 원석불출피더(2)에 의해 석회석(33)이 베켄베치 킬른에 장입 되는데 30~40 mmH2O 정도의 부압으로 운전되기 때문에 장입호퍼(1)는 2중으로 밀폐된 구조로 이루어지며 간헐적으로 장입된다.1 and 2, limestone 33 is charged into the Beckenbech kiln by the raw stone discharge feeder 2 according to the production amount set in the charging hopper 1 as shown in FIGS. 1 and 2. Since it is operated at a negative pressure of about 40 mmH 2 O, the charging hopper 1 has a double sealed structure and is intermittently charged.

베켄베치 킬른에 장입된 석회석(33)은 예열대(52)에서 배가스와의 접촉에 의해 열교환이 이루어져 탄산칼슘의 분해온도까지 예열되어진다. 하강한 석회석(33)은 소성대(53)에서 연료인 C.O.G의 연소 즉, 상부버너(21)와 하부버너(8)에 의해 열을 얻어 탈탄산이 행해지고, 산화칼슘이 되어 냉각대(54)에 들어간다.Limestone 33 charged in the Beckenbech kiln is heat-exchanged by contact with the exhaust gas in the preheating zone 52 and is preheated to the decomposition temperature of calcium carbonate. The lowered limestone 33 is burned in the baking table 53 to burn COG as fuel, that is, heat is obtained by the upper burner 21 and the lower burner 8, and decarbonate is performed to form calcium oxide. Enter

냉각대(54)에서는 생석회가 밑에서 넣어진 냉각공기와 열교환하고 고온의 생석회는 100℃까지 냉각되며, 생산된 생석회는 테이블디스챠지(11)에 의해 테이블디스챠지 하단으로 불출되고, 제품불출피더(16)에 의해 제품공정으로 불출된다.In the cooling zone 54, the quicklime is exchanged with the cooling air put underneath, and the hot lime is cooled to 100 ° C, and the produced quicklime is discharged to the bottom of the table discharge by the table discharge 11, and the product discharge feeder ( 16) is dispensed into the product process.

소성중 베켄베치 킬른에서 발생된 레큐배가스와 킬른배가스는 총배가스로 합해진 후 사이클론(13)으로 집진되며, 팬(12)에 의해 배기되고 벤츄리스크루버(18)에서 집진수에 의해 수세식으로 집진된 후에 슬러지는 집진수폰드(17)로 보내짐과 동시에 집진된 총배가스(15)는 굴뚝(26)으로 배기되게 된다.Recue gas and kiln flue gas generated in the Beckenbeck kiln during firing are combined into total flue gas and collected in a cyclone (13), exhausted by a fan (12), and collected by washing with a dust in the venturi screw (18). Later, the sludge is sent to the dust collecting pond 17 and the collected total exhaust gas 15 is exhausted to the chimney 26.

그런데, 로 본체의 내부에는 강제냉각방식의 중통(25)이 설치되어 있으므로 로의 축방향에 구성된 소성대(53)의 범위는 넓은 반면 원석이 통과되는 폭은 좁은 형태를 가진다.By the way, since the barrel 25 of the forced cooling system is installed in the furnace body, the range of the firing table 53 formed in the axial direction of the furnace is wide while the width of the raw stone passes is narrow.

그리고, 로 외부에는 레큐피레이터(4)를 설치하여 연소공기블로어(5)에 의해 공급되는 각 버너의 인젝터(7) 작동공기를 예열하고 중통냉각공기 블로워(24)에 의해 중통(25)을 강제냉각시킨 중통냉각공기(27)는 2차공기 링튜브(23)에 모아지며 각 버너의 2차공기로서 사용되고 남는 것은 2차공기 방산조절변(28)에 의해 방산2차공기(29)로서 대기로 방산된다.Then, a recuperator 4 is installed outside the furnace to preheat the operating air of the injector 7 of each burner supplied by the combustion air blower 5, and the central cylinder 25 is opened by the central cooling air blower 24. Forced cooling medium cylinder cooling air (27) is collected in the secondary air ring tube (23) and used as secondary air of each burner and left as secondary air (29) dissipated by secondary air dissipation control valve (28). Dissipated to the atmosphere

베켄베치 킬른 정지시에도 중통냉각공기 블로워(24)는 중통(25)의 변형을 방지하기 위하여 계속 가동되는데, 이때는 중통(25)을 강제냉각시킨 후 2차공기 링튜브(23)에 모아지고 난 후 전량 2차공기 방산조절변(28)에 의해 대기로 방산된다.Even when the Beckenbech kiln stops, the central cool air blower (24) continues to operate to prevent deformation of the main cylinder (25). In this case, the central cylinder (25) is forcedly cooled and collected in the secondary air ring tube (23). After the total amount is discharged to the atmosphere by the secondary air dissipation control valve 28.

중통냉각공기 블로워(24)는 베켄베치킬른 정지시 뿐만 아니라 정전 등의 경우에도 계속 가동되어야 하므로 전원 인입의 2중화와 더불어 비상발전기를 갖추어 상시 가동 가능한 상태를 유지하도록 이루어진다. Since the medium-cooled air blower 24 should be operated continuously as well as at the time of the Beckenbeckian kiln stop, such as a power outage, it is equipped with an emergency generator along with the duplication of power supply to maintain the state of continuous operation.

이때, 석회소성로 내부를 순환하는 순환가스(34)는 냉각대(54)에서 생석회를 냉각하고 상승하는 냉각공기와 하부버너연소실(9)에서의 연소가스 일부가 드라이빙공기(37)의 흡입에 의해 발생되므로 분생석회를 다량 포함하게 된다.At this time, in the circulating gas 34 circulating in the lime kiln, the cooling air rising and cooling the quicklime in the cooling zone 54 and a part of the combustion gas in the lower burner combustion chamber 9 are sucked by the driving air 37. As a result, it contains large amounts of conidia.

그런데, 소성조업이 진행될 수록 순환가스(34)에 함유된 분생석회가 선회실(22)에 쌓이면서 더스트화되고, 누적더스트의 양이 많아지면서 순환가스(34)의 흐름을 방해하게 되어 순환가스(34)의 흐름이 원활하지 않게 된다.However, as the firing operation proceeds, the condensed lime contained in the circulating gas 34 is dusted as it accumulates in the turning chamber 22, and the amount of accumulated dust increases, which hinders the flow of the circulating gas 34 and thus the circulating gas ( 34) the flow is not smooth.

이로 인해, 하부버너(8)의 연소공기 부족현상, 이에 따른 연소불량, 조로관 리의 불안정에 기인한 생석회의 품질하락, 부압이 안정적으로 유지되지 못하여 유발되는 역화에 의한 안전사고의 위험 등 상당한 문제들을 파생시키게 된다.Due to this, there is a considerable problem such as a shortage of combustion air of the lower burner 8, resulting in poor combustion, deterioration of quicklime due to instability of blast furnace management, and a risk of safety accident due to backfire caused by inability to maintain negative pressure. To derive them.

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 창안한 것인 바, 순환가스에 함유된 더스트가 선회실에 쌓이지 못하도록 주기적으로 이를 제거처리하여 가스의 순환을 원활하게 함으로써 제품의 품위 향상은 물론 연료의 과다 소비를 막고 생산량도 가일층 향상시킬 수 있도록 한 석회소성로 순환가스 선회실의 누적 더스트 배출장치를 제공함에 그 목적이 있다.The present invention has been devised to solve such a conventional problem, by periodically removing the dust contained in the circulating gas to prevent the dust from accumulating in the turning room to smooth the circulation of the gas as well as improve the product quality as well as fuel The aim is to provide a cumulative dust discharge device for the circulating gas circulating chamber of the lime kiln to prevent excessive consumption and further improve production.

본 발명의 상기한 목적은, 석회소성로의 하부버너가 설치되고 순환가스가 순환되는 부분인 선회실의 하단면과 제품불출피더의 인접상측인 디스차징챔버를 연통되게 연결시키는 더스트배출관과; 상기 더스트배출관의 길이 중앙부에 형성된 서지호퍼를 중심으로 그 상측인 선회실을 향한 길이 일부에 이를 선택적으로 개폐하도록 설치된 상부전동댐퍼와; 상기 서지호퍼를 기점으로 상기 상부전동댐퍼와 대향되는 위치의 더스트배출관상에는 상기 상부전동댐퍼와 반대작동되게 설치된 하부전동댐퍼를 포함하여 구성되는 것을 특징으로 하는 석회소성로 순환가스 선회실의 누적 더스트 배출장치를 제공함에 의해 달성된다.The above object of the present invention, the lower burner is installed in the lime burner furnace and the dust discharge pipe for connecting the discharging chamber adjacent to the upper surface of the product discharge feeder and the lower surface of the turning chamber which is the circulating gas circulation portion; An upper electric damper installed to selectively open and close a portion of the length of the dust discharge pipe toward the swinging chamber at an upper side of the surge hopper formed at the center of the dust discharge pipe; Cumulative dust discharge of the lime-fired furnace circulating gas swing room, characterized in that it comprises a lower electric damper installed opposite to the upper electric damper on the dust discharge pipe at the position opposite to the upper electric damper starting from the surge hopper. By providing a device.

이하에서는, 첨부도면을 참고하여 본 발명을 보다 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 3은 본 발명 장치의 설치상태를 보인 것이고, 도 4는 본 발명 장치의 요 부를 확대하여 보인 것이다.Figure 3 shows the installation of the device of the present invention, Figure 4 is an enlarged view of the main portion of the device of the present invention.

도 3 및 도 4에 따르면, 선회실(22)의 하단면에는 더스트배출관(80)의 상단이 연결되고, 상기 더스트배출관(80)의 하단은 제품불출피더(90)의 인접 상측공간인 디스차징챔버(92)와 연통되게 연결된다.According to FIGS. 3 and 4, the upper end of the dust discharge pipe 80 is connected to the lower end surface of the turning room 22, and the lower end of the dust discharge pipe 80 is discharged as an adjacent upper space of the product discharge feeder 90. It is connected in communication with the chamber 92.

뿐만 아니라, 상기 더스트배출관(80)의 하단을 별도의 더스트포집용기와 같은 것과 연결시켜 곧바로 포집처리할 수도 있을 것이다.In addition, the lower end of the dust discharge pipe 80 may be connected to the same as a separate dust collection container and may be collected immediately.

그리고, 상기 더스트배출관(80)의 길이 일부에는 서지호퍼(29)가 설치되고, 상기 서지호퍼(29)를 기준으로 하여 그 상측인 상기 선회실(22) 측을 향한 더스트배출관(80)의 일부에는 상부전동댐퍼(84)가 설치되고, 상기 서지호퍼(29)를 기준으로 그 하측인 상기 제품불출피더(90)측 길이 일부에는 하부전동댐퍼(86)가 설치된다.In addition, a part of the length of the dust discharge pipe 80 is provided with a surge hopper 29, and a part of the dust discharge pipe 80 toward the pivot chamber 22, which is an upper side thereof, based on the surge hopper 29. The upper electric damper 84 is installed, and the lower electric damper 86 is installed at a part of the length of the product dispensing feeder 90 that is lower than the surge hopper 29 as a reference.

상기 상부 및 하부전동댐퍼(84,86)들은 전원의 통전에 의해 선택적으로 작동되면서 상기 더스트배출관(80)의 일부를 완전히 밀폐할 수 있도록 구성되는데, 통상 전자석을 응용한 댐퍼구조를 취함이 바람직하다.The upper and lower electric dampers 84 and 86 are selectively operated by energization of a power source, and are configured to completely seal a part of the dust discharge pipe 80. It is preferable to take a damper structure using an electromagnet. .

특히, 소성로의 내부 부압 유지를 위해 상기 상하부전동댐퍼(84,86)는 동시에 개방될 수 없는 구조를 가져야 한다. 즉, 적어도 어느 하나는 반드시 폐쇄되어 있어야 한다.In particular, in order to maintain the internal negative pressure of the kiln, the upper and lower electric dampers 84 and 86 should have a structure that cannot be opened at the same time. That is, at least one must be closed.

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

종래 기술중에서 서술했던 석회소성로의 가스 흐름관계에 의해 순환하던 더스트를 함유한 순환가스가 선회실(22)로 유입되면서 선회실(22)의 바닥면에 더스트 가 떨어지게 된다.As the circulating gas containing the dust circulated by the gas flow relationship of the lime baking furnace described in the prior art flows into the turning chamber 22, the dust falls on the bottom surface of the turning chamber 22.

떨어진 더스트는 자중이나 혹은 순환가스 및 작동공기 등의 압력변화에 의해 선회실(22)의 하단면에 연결설치된 더스트배출관(80)을 통해 낙하되게 된다.The fallen dust is dropped through the dust discharge pipe 80 connected to the lower surface of the swinging chamber 22 due to its own weight or pressure change such as circulating gas and working air.

낙하된 더스트는 상부전동댐퍼(84)에 의해 밀폐된 상태를 유지하고 있는 부위에 누적되게 되고 이 지점은 선회실(22)보다 훨씬 하방향에 위치되게 된다.The dropped dust accumulates in the part which is kept closed by the upper electric damper 84, and this point is located much lower than the turning chamber 22. As shown in FIG.

주기적인 신호나 혹은 운전자의 작업신호에 의해 상부전동댐퍼(84)가 개방되게 되면 누적되어 있던 더스트는 서지호퍼(82)측으로 완전 배출되게 된다.When the upper electric damper 84 is opened by a periodic signal or a driver's work signal, the accumulated dust is completely discharged to the surge hopper 82.

그 전에, 소성로의 부압 유지를 위해 하부전동댐퍼(86)는 밀폐된 상태를 유지하게 된다.Before that, the lower electric damper 86 is kept closed in order to maintain the negative pressure of the kiln.

서지호퍼(82)를 통해 원활한 흐름성을 갖게 된 더스트는 다시 하강하여 하부전동댐퍼(86)의 상측에 머무르게 되고, 이때 상부전동댐퍼(84)가 폐쇄되게 된다.The dust having a smooth flow through the surge hopper 82 is lowered again to stay on the upper side of the lower electric damper 86, the upper electric damper 84 is closed.

상부전동댐퍼(84)의 폐쇄에 따른 제어신호가 수신되면 그와 동시에 하부전동댐퍼(86)가 개방되면서 그 상측에 머무르고 있던 더스트들을 하측으로 완전 배출처리하게 된다.When the control signal according to the closing of the upper electric damper 84 is received, the lower electric damper 86 is opened at the same time to completely discharge the dust staying on the upper side to the lower side.

따라서, 소성로의 부압에는 변동을 주지않으면서 선회실(22)에 누적되던 더스트를 용이하게 제거할 수 있게 된다.Therefore, it is possible to easily remove dust accumulated in the swinging chamber 22 without causing fluctuations in the negative pressure of the kiln.

이상에서 상세히 설명한 바와 같이, 본 발명은 선회실에 더스트의 누적이 없어져 순환가스의 순환작용이 원활하게 유지됨으로써 연소효율의 향상은 물론 로내 부압을 균일하게 유지할 수 있어 로황관리가 유리하고 고품위 소성제품을 생산할 수 있게 된다.As described in detail above, in the present invention, there is no accumulation of dust in the turning room, so that the circulation operation of the circulating gas is smoothly maintained, thereby improving combustion efficiency as well as maintaining the negative pressure in the furnace uniformly, so that the furnace sulfur management is advantageous and high quality plastic products. Will be able to produce.
