Description

슬러지 건조장치Sludge drying equipment

본 고안은 하수처리장, 식품공장, 제지공장등 각종 산업공장에서 배출되는 슬러지를 악취와 분진등이 발생치 않도록 완전건조하는 슬러지 건조장치에 관한 것이다.The present invention relates to a sludge drying apparatus for completely drying the sludge discharged from various industrial plants such as a sewage treatment plant, a food factory, a paper mill, and the like to prevent odors and dusts.

종래 하수처리장등 각종 산업체 공장에서 배출되는 슬러지는 필터프레스에 의거하여 수분을 분리하는 방법과 가열하여 열건조하는 방법으로 처리하고 있으나, 전자는 수분이 분리된 슬러지를 다시 건조하거나 연소시켜야 되는 번거러움이 있으므로 근래에 와서는, 후자의 방법을 많이 사용하고 있는바, 종래 열건조장치는 슬러지를 단순히 가열시켜 건조하게 되므로 건조실에서 발산되어 배출되는 증기에 수분이 혼합되어 그대로 배출하는 과정에서 악취가 많이 발생하는 문제점이 있었고 또한 분진도 대량 배출되어 별도의 집진시설을 필요로 하므로 기계설비 비용이 과다하게 소요되는등 여러가지의 많은 폐단이 있었다.Conventionally, sludge discharged from various industrial factories, such as sewage treatment plants, is treated with a method of separating water based on a filter press and a method of heating and heating to dry it. Therefore, in recent years, the latter method has been used a lot, the conventional heat drying apparatus is simply heated by heating the sludge to dry, so that a lot of odor occurs in the process of discharging as it is mixed with moisture in the steam discharged from the drying chamber In addition, since a large amount of dust is discharged and requires a separate dust collecting facility, there are many wastes such as excessive cost of machinery equipment.

본 고안은 이와같은 점을 감안하여 건조실에서 가열로 인해 배출되는 가스를 증기와 분리하여 이를 연소실에서 재연소시키므로서 재연소와 함께 수분을 완전히 제거하여 악취의 발생을 해소한 것인데 이를 첨부도면에 의거 상술하면 다음과 같다.In view of the above, the present invention separates the gas discharged by heating in the drying chamber from the steam and re-burns it in the combustion chamber, thereby completely eliminating moisture along with the re-burning to eliminate the occurrence of odor. The above is as follows.

To the upper part of the steam separator (b) and the plurality of coolant feed water nozzles 11 and 11 'installed therein, and inductively connects the gas pipe 12 which is discharged to the lower part to the combustion chamber 3, The ceramic reburner in which the ceramic tubes 16 and 16 'are interpolated innumerably in the cylindrical body 15 having the upper and lower portions formed by the stainless steel net 14 in the exhaust pipe 13 connected to the upper part of 17) is characterized in that by installing.

도면중 미설명부호 18은 재회수관이고, 19는 슬러지 투입관(5)에 설치한 개폐판이며, 20은 개폐판(19)을 작동시키는 실린더이고, 21은 급수관이다.In the figure, reference numeral 18 is a reclaimed pipe, 19 is an opening and closing plate installed in the sludge inlet pipe 5, 20 is a cylinder for operating the opening and closing plate 19, 21 is a water supply pipe.

이와 같이된 본 고안은 슬러지가 슬러지 이송관(2)의 이송스크류(1)에 의거 이송되어 슬러지 투입관(5)을 통해 건조실(4)로 낙하 투입되면 슬러지는 건조실(4)의 내부에서 회전되는 교반축(7)의 교반익(6)(6')에 의거 뒤집어지면서 섞이고 교반이 이루어지게 되는데, 건조실(4)은 단열재로 둘러싸인 연소실(3)의 내부에 설치되어 있고 연소실(3) 내부의 건조실(4)의 저부에는 주버너(8)와 보조버너(9)(9')가 설치되어 있으므로 연소실(3)과 건조실(4)은 버너(8)(9)(9')의 화염에 의해 가열되므로서 건조실(4) 내부의 슬러지는 교반익(6)(6')에 의해 교반되면서 가열건조가 이루어지게 된다.The present invention as described above is sludge is rotated in the drying chamber (4) when the sludge is transferred to the drying chamber 4 through the sludge feed pipe (2) is transferred to the drying chamber 4 through the sludge feed pipe (2). The mixing blade is turned upside down according to the stirring blades 6 and 6 'of the stirring shaft 7 to be mixed and agitated. The drying chamber 4 is installed inside the combustion chamber 3 surrounded by a heat insulating material and is inside the combustion chamber 3. The combustion chamber 3 and the drying chamber 4 are flames of the burners 8, 9, 9 'because the main burner 8 and the auxiliary burners 9, 9' are provided at the bottom of the drying chamber 4 of the combustion chamber. As it is heated by the sludge inside the drying chamber (4) is heated and dried while stirring by the stirring blades (6) (6 ').

이와 같이 건조실(4)이 가열되어 내부의 슬러지가 가열 건조되면 슬러지에 포함된 수분으로 인해 증기가 발생되는데 건조실(3)에 설치된 슬러지 투입관(5)에는 증기배출관(10)이 연결되어 그 단부가 냉각수 급수노즐(11)(11')이 다수개 설치된 증기와 가스분리기(나)의 상부에 연결되어 있으므로 슬러지 투입관(5)의 개폐판(19)을 닫은 상태에서 건조실(4)이 가열되면 그 내부에서 발생된 많은 양의 증기와 가스는 증기배출관(10)을 통해 증기와 가스분리기(나)로 유입되어 냉각수 급수노즐(11)(11')에서 분사되는 냉각수에 의거 포집되는데 이때, 수증기는 냉각수와 혼합되어 비중에 의해 저부로 낙하되고 증기가 분리된 가스만이 하부의 가스관(12)을 통해 연소실(3)로 다시 유입되어 버너(8)(9)(9') 화염에 의한 재연소가 이루어져 완전연소가 되며, 완전연소된 연소실(3)의 배기가스는 이에 연결설치된 배기관(13)을 통해 대기중으로 방출되어지게 된다.As such, when the drying chamber 4 is heated and the sludge inside is heated and dried, steam is generated due to the moisture contained in the sludge. The steam discharge pipe 10 is connected to the sludge inlet pipe 5 installed in the drying chamber 3 and the end thereof The drying chamber 4 is heated while the opening and closing plate 19 of the sludge inlet pipe 5 is closed since the cooling water feed nozzles 11 and 11 'are connected to the upper portion of the steam separator and the gas separator (b). When a large amount of steam and gas generated therein is introduced into the steam and gas separator (b) through the steam discharge pipe (10) is collected based on the cooling water sprayed from the cooling water feed nozzles (11) (11 '), Water vapor is mixed with the cooling water and dropped to the bottom by specific gravity, and only the gas from which steam is separated is introduced again into the combustion chamber 3 through the lower gas pipe 12, and burned by the burners 8, 9, 9 '. Complete combustion, complete combustion The exhaust gas 3 is be emitted into the atmosphere through the exhaust pipe 13 connected thereto are installed.

한편, 배기관(13)에는 원통체(15)의 내부에 세라믹튜브(16)(16')를 무수히 내삽한 세라믹 재연소기(17)가 설치되어 있으므로 배기관(13)으로 배출되는 배기가스는 스텐레스망(14)을 통해 세라믹튜브(16)(16')를 거친 다음 다시 상부의 스텐레스망(14)을 통해 대기중에 배출되므로 배기가스는 세라믹튜브(16)(16')의 보열성과 열보존성등으로 인해 더욱 가열되어 거의 완전 연소상태로 재연소된 후 대기중에 배출되므로 대기오염을 방지하고 악취가 발생되지 않게 되는 것이다.On the other hand, since the exhaust pipe 13 is provided with a ceramic reburner 17 in which the ceramic tubes 16 and 16 'are inserted innumerably in the cylindrical body 15, the exhaust gas discharged to the exhaust pipe 13 is made of stainless steel. After passing through the ceramic tubes 16 and 16 'through 14, the exhaust gas is discharged to the atmosphere through the upper stainless steel net 14, so that the exhaust gas retains heat retention and heat retention of the ceramic tubes 16 and 16'. Because of this, it is further heated to be re-burned to a nearly complete combustion state and then discharged into the atmosphere, thereby preventing air pollution and preventing odors.

이와같이 본 고안은 건조실(4)에서 발생되는 가스를 증기와 분리시켜 이를 다시 연소실(3)에서 재연소시키므로서 완전연소가 이루어져 악취 발생이 전혀 없고, 분진이 발생하지 않아 2차 집진시설을 필요로 하지 않으므로 기계 설비 부담이 경감되는등 그 효과가 매우 크다.As such, the present invention separates the gas generated in the drying chamber 4 from the steam and re-burns it again in the combustion chamber 3 so that complete combustion occurs and no odor is generated and dust is not generated. Therefore, the effect is very large, such as the burden on the mechanical equipment is reduced.
