본 발명은 양질의 망초와 염산의 제조방법과 그 제조장치에 관한 것으로서, 특히 반응탱크와 싸이쿠론장치 및 염반응탱크가 일련으로 구성되는 하나의 장치에서 염분과 So2가스 및 수증기와 공기를 유동반응시켜 짧은 시간에 염분이 없는 양질망초와 염산을 다량으로 생산할 수 있게 하여 제품의 제조원가를 절감시킬 수 있고 또한 생산량을 극대화 시킬 수 있을 뿐아니라 장치자체를 소형화시켜 시설비도 절감할 수 있도록 한 양질의 망초와 염산의 제조방법 및 그 장치에 관한 것이다.The present invention relates to a method for producing high quality forget-me-not and hydrochloric acid, and an apparatus for manufacturing the same, in particular, a salt, So 2 gas, water vapor, and air flow in one apparatus consisting of a reaction tank, a cyclone apparatus, and a salt reaction tank. It is possible to produce a large amount of high quality salt-free forget-me-not and hydrochloric acid in a short time, thereby reducing the manufacturing cost of the product and maximizing the yield, and minimizing the device itself to reduce the facility cost. The present invention relates to a method for producing forget-me-not and hydrochloric acid, and an apparatus thereof.

일반적인 종래의 망초와 염산의 제조방법을 보면 높이가 약 5m정도되는 대형탱크를 수개 설치하고 이를 각각 동시에 가동시키면서 각 탱크내에 2~3㎜ 정도의 입방체로된 염을 장입하고, 동탱크를 가열버어너로 가열하여 내부온도가 약 500~550℃ 정도로 유지되게 가열하면서 So2가스, 수증기, 공기등을 적당량 각각의 탱크내에 투입하면 장입된 성형열층을 상기 가스, 수증기, 공기등이 통과하면서 상호 반응하여 조망초와 염산을 생산하게 되는데 이 기간은 약 3~4주간 정도이며, 이때에 대략 반응이 완료되어 작업을 정지하고, 조망초를 반출하고, 다시 상기와 같이 성형열을 동탱크내에 가하고, 염을 장입하는 동작방법을 반복하여, 조망초와 염산을 생산하였던 것이다. 상기와 같은 종래의 방법에 의해 생산된 조망초는 염분이 미반응으로 다량함유되어 다시 별도의 정제장치에 의하여 정제하여야 하는 등 작업공수가 증가되어 생산기간이 길어져 생산성이 저하되어 제조원가를 상승시키는 요인이 되었고, 또한 인력과 시간의 손실이 많고, 전체적인 설비가 크고 복잡하여 시설비가 과다하게 투자되며, 이에 따라 경제성이 저하되고, 생산비의 과중등으로 기업성이 결여되어 실효가치가 없었던 것이다.According to the conventional manufacturing method of the forget-me-not and hydrochloric acid, several large tanks having a height of about 5 m are installed, and each of them is operated at the same time, and a salt of 2 to 3 mm cube is charged into each tank, and the copper tank is heated. When heated by an inner and heated to maintain an internal temperature of about 500 ~ 550 ℃, and So 2 gas, steam, air, etc. are introduced into each tank, the charged forming heat layer passes through the gas, water vapor, air, etc. It is produced for about 4-4 weeks, and this period is about 3-4 weeks, at which time the reaction is completed, stop the work, take out the view and then the forming heat is added to the copper tank as described above, By repeating the operation of charging the salt, it was to produce the perichocho and hydrochloric acid. Viewed flowers produced by the conventional method as described above have a large amount of unreacted salt, which must be purified again by a separate refining apparatus, and thus increase the labor time, resulting in a long production period, resulting in a decrease in productivity. In addition, there is a lot of loss of manpower and time, and the overall equipment is large and complex, so the facility cost is excessively invested. As a result, the economic feasibility is low, and due to the excessive production cost, there is no effective value.

In the reaction tank 2, a salt inlet 8 is installed at an upper portion thereof, and an inclined guide feather 9 and a heating tube 10 for guiding salt injected therein. It is installed through this ″ ㄹ ″ shape. In addition, the upper part of the reaction tank (2) is connected to the air inlet pipe 11 and the So 2 gas injection pipe 12 and the steam injection pipe 13 is configured, the lower burner 14 for heating Is configured.

또한 상기 싸이쿠론장치(4)의 하부에는 망초배출구(15)가 그리고 일측에는 연돌(16)이 설치되고, 이와 염반응탱크(7)는 연결도관(6)에 의해서 연결설치 구성된다. 또한 상기 염반응탱크(7)의 하부로는 가열장치(17)와 망초배출구(15′)가 연결설치되며, 상단 일측에는 공지의 염산흡수장치(18)와 연결되는 Hcl 도관(19)이 연결구성된다. 상기와 같이 구성된 본 발명의 장치는 공지의 제어콘트롤에 의해서 연속적인 동작이 가능하도록 구성되어 있다.In addition, the lower part of the cyclone device (4) is the forage outlet 15 and the chimney 16 is installed on one side, and the salt reaction tank (7) is connected to the installation by the connecting conduit (6). In addition, the lower portion of the salt reaction tank (7) is connected to the heating device (17) and the forget-out outlet (15 '), the upper side is connected to the Hcl conduit 19 is connected to the known hydrochloric acid absorbing device (18) It is composed. The device of the present invention configured as described above is configured to enable continuous operation by a known control control.

이상과 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

먼저 본 발명장치(1)의 선단 반응탱크(2)를 하부의 가열버어너(14)로서 가열시켜 내부온도가 약 500~550℃ 정도로 가열되면 반응탱크(2)의 상부 염주입구(8)를 통하여 분쇄된 염분을 투입함과 동시에 So2가스 주입관(12)을 통하여 So2가스를 정량 주입하고, 공기주입관(11)과 수증기주입관(13)을 통하여 각각 공기와 수증기를 적당량 투입하여 준다. 이때 투입되는 반응탱크(2) 내부에 설치된 경사안내깃(9)들에 의해서 내.외측으로 변경이동하면서 하강하게 되는 것이다. 이때 반응탱크(2)내에 주입되는 염분과 So2가스 및 수증기와 공기가 유동반응하면서 상기 반응탱크(2)의 하부에 도달하게 되면 이 하측에 설치되어 있는 특수 휀(3)이 작동하여 강한 풍압으로 하강하는 반응물을 강하게 배출시키면 이에 연결된 배출도관(5)을 통해 반응탱크(2) 일측의 싸이쿠론장치(4)로 공급된다.First, the tip reaction tank 2 of the present invention device 1 is heated as a lower heating burner 14, and when the internal temperature is heated to about 500 to 550 ° C., the upper salt inlet 8 of the reaction tank 2 is opened. While the crushed salt is added through the So 2 gas injection tube 12, the So 2 gas is injected quantitatively, and an appropriate amount of air and steam through the air injection pipe 11 and the steam injection pipe 13, respectively give. At this time, the inclined guide feathers (9) installed in the reaction tank (2) to be introduced is to change while moving in and out. At this time, when the salt injected into the reaction tank 2 and the So 2 gas, water vapor and air flows to reach the lower portion of the reaction tank 2, the special fin (3) installed on the lower side is operated to generate a strong wind pressure. Strongly discharging the descending reactant is supplied to the cyclone apparatus 4 on one side of the reaction tank 2 through the discharge conduit 5 connected thereto.

이때 싸이쿠론장치(4)가 동작하여 반응물을 고형물과 기체의 대부분을 분리하여 주면, 기체는 가열된 연결도관(6)을 통하여 성형 염반응탱크(7)로 보내지고, 이때 싸이쿠론장치(4)에서 분리된 망초는 하부 망초배출구(15)를 통하여 1차로 제조된 망초가 배출되게 된다.At this time, the cyclone apparatus 4 operates to separate the reactants from the solids and most of the gas, and the gas is sent to the molded salt reaction tank 7 through the heated connecting conduit 6, wherein the cyclone apparatus 4 ) Is separated from the first through the lower forget-me-not outlet 15 is the first manufactured forget-me-not.

또한 염반응탱크(7)에 보내진 기체는 500~550℃로 가열되는 염반응탱크(7) 내부로 통과하면서 내부에 채워진 염과 당시 반응을 하게 된다. 이때 생성된 2차 망초는 염반응탱크는(7) 하부에 망초배출구(15′)를 통하여 배출되고 반응된 기체는 이 염반응탱크(7) 상부에 연결된 Hcl 도관(19)을 통하여 공지의 Hcl 흡수장치(18)로 유도되어 염산이 제조되어 진다.In addition, the gas sent to the salt reaction tank 7 is reacted with the salt filled therein while passing through the salt reaction tank 7 heated to 500 ~ 550 ℃. At this time, the secondary manganese produced by the salt reaction tank (7) at the bottom through the outlet port (15 ') and the reacted gas through the Hcl conduit (19) connected to the top of the salt reaction tank (7) known Hcl Hydrochloric acid is produced by introducing into the absorber (18).

이상에서 설명한 바와같이 본 발명은 분말염을 가열되는 반응탱크에 So2가스와 수증기 및 공기와 함께 주입하여 유동반응되게 하면서 휀으로서 싸이쿠론장치로 보내지고 여기서 기체와 고형물이 분리되어 1차로 망초를 제조하고, 이어 기체는 다시 염이 채워진 염반응탱크를 거치면서 반응하여 2차로 망초가 제조되어지며, 이때 생성된 가스는 Hcl 도관을 통하여 Hcl 흡수장치로 보내지게 되어 여기서 염산이 제조되는 것이다.As described above, the present invention is a powder salt is injected into the heated reaction tank together with So 2 gas, water vapor and air to flow the reaction while being sent to the cyclone device where the gas and solids are separated to the primary forage Then, the gas is reacted again through a salt-filled salt reaction tank, whereby a second step is prepared, and the generated gas is sent to the Hcl absorber through the Hcl conduit where hydrochloric acid is produced.

이때 투입되는 So2가스는 염의 당량보다 과잉상태로 하는 것이 좋다. 이와같이 일련의 장치를 염분과 수증기 및 So2가스와 공기가 유동되어 반응하면서 통과하는 공정으로 양질의 망초와 염산이 제조되므로, 단위 시간당 작업능률이 극대화되어 제품의 제조원가를 절감시킬 수 있고, 또한 장치자체의 설비를 간소화 할 수 있고 경제적이고, 현실적으로 부합 될 수 있어 기업성을 충족시킬 수 있으며, 제조공정시간이 짧아 많은 량을 적은 인력과 시간으로 생산할 수 있는 획기적인 발명인 것이다.At this time, the So 2 gas to be introduced is preferably in an excess state than the equivalent of salt. In this way, high-quality forget-me-not and hydrochloric acid are produced by passing through a series of devices through the reaction of salt, water vapor, So 2 gas, and air, which maximizes the work efficiency per unit time and reduces the manufacturing cost of the product. It is a revolutionary invention that can simplify its own equipment, meet economical and realistically meet the enterprise, and can produce a large amount with a small manpower and time due to the short manufacturing process time.
