のであつた。 Slaked lime slurry is injected into the reaction evaporation tower, which removes harmful gases from exhaust gas emitted from garbage incineration equipment, boilers, and other combustion equipment, to treat harmful gases, so slurry-like substances adhere to the inner walls of the tower. It accumulates and reduces its function. In addition, slurry-like substances adhere to the inner wall surface of the drying chamber of general spray drying equipment used in the process of manufacturing powdered milk, etc., and gradually accumulate and become solid, reducing the drying function. In the past, when the deposits adhering to the wall surface gradually solidified and developed into layers, it was unavoidable to temporarily suspend operation and remove the deposits manually. This work of removing deposits not only significantly lowers the efficiency of operation, but also requires a great deal of labor to remove them.

６にフランジを介して連結されている。 Next, the present invention will be explained based on an embodiment shown in the drawings. This embodiment is a device for a reaction evaporation tower installed to reduce harmful hydrogen chloride components contained in waste gas from a garbage incinerator to below legal standards and release them into the atmosphere. The main part of the reaction evaporation column 1 is a cylindrical reaction evaporation chamber 2 with an open bottom, and a constriction part 3 is formed at the bottom of the cylindrical reaction evaporation chamber 2. The lower part of the throttle section 3 communicates with an untreated gas supply chamber 4 having a circular planar cross section. The untreated gas supply chamber 4 has an eccentric supply port 5 opened on the side wall, and a chemical (slaked lime slurry) injection pipe 6 whose upper part opens to the throttle section 3 of the reaction evaporation column 1 in the center.
is erected, and further provided with a rotary valve 7 guided in a trap type on the circumferential side and driven by a motor (not shown). A processing gas exhaust port 8 is opened in the upper side wall of the reaction evaporation chamber 2.
An exhaust pipe equipped with an exhaust pump or an exhaust fan (not shown) is connected to the exhaust pipe. Chemical injection pipe 6
A nozzle 9 is attached to the tip of the nozzle 9, and the nozzle 9 injects the chemical into the reaction evaporation chamber 2 in a widening direction at the constriction portion 3. A cross-shaped rotating member 11 is horizontally and rotatably suspended from the upper end plate 10 in the upper part of the reaction evaporation chamber 2, and the end of the rotating member 11 extends to the vicinity of the side wall of the reaction evaporation column 1. Rotating member 11
A plurality of chains 12 are attached to the chain 12 in a hanging manner. Reference numeral 13 denotes a hanging shaft erected at the center of the rotating member 11, the upper end of which passes through the upper end plate 10 via a bearing 17, and a reducer installed on a pedestal 14 fixed to the center of the end plate 10.

ルブ７によつて塔外に除去される。 A plurality of pieces 20 are attached to the wall surface of the reaction evaporation chamber 2. When the dust incinerator is operated, the exhaust pump or exhaust fan of the exhaust pipe (not shown) is driven at the same time, and the exhaust gas of the dust incinerator, that is, the untreated gas is discharged from the gas supply port 5 as shown by the white arrow 18. When the untreated gas is sucked into the gas supply chamber 4, it is given a swirling motion by the eccentric mounting of the gas supply port 5, and is accelerated by the throttle of the throttle section 3, and rises while swirling inside the reaction evaporation chamber 2. On the other hand, the slaked lime slurry forced into the chemical injection pipe 6 is radially injected diagonally upward from the nozzle 9 in the direction of the arrow shown by the solid line. Sufficient mixing and contact is carried out within the chamber, reacting with hydrogen chloride in the untreated gas, producing calcium chloride, and eliminating hydrogen chloride, which was a harmful component in the untreated gas. Since the temperature of the exhaust gas in the reaction evaporation chamber 2 is about 300°C, the fine particles of calcium chloride containing water are solidified and fall to the bottom of the untreated gas supply chamber 4 by gravity, whereupon the untreated gas is released. As it rotates, it is moved toward the circumference, and during the rotation, it falls into the trap-shaped socket of the rotary valve 7 and is removed by the valve 7 from the column.

出れる。 However, a portion of the ejected fine particles of the slaked lime slurry and a portion of the generated slurry calcium chloride adhere to the chains 12 and the inner wall surface of the reaction evaporation chamber 2 and solidify, forming successive layers. The suspended chain 12 is forcibly rotated and removed before the deposits form a layer on the inner circumferential wall surface of the reaction evaporation chamber 2. In other words, after the required time has elapsed while the furnace is in operation. The motor 15 is rotated (2 to 10 r.Pm) to drive the rotating member 11 and the chain 12 is rotated along the inner wall surface of the reaction and evaporation chamber 2, and the centrifugal force strongly rubs the wall surface and the inner wall of the reaction and evaporation chamber 2 is rotated. A piece 20 having a protrusion B larger than the clearance A between the chain 12 and the inner wall of the reaction and evaporation chamber 2 is installed at an appropriate position, and by hitting the chain 20 with the piece 20, a shock is applied to the chain 2 and the chain 2 is scaled. prevent. At the same time, the deposits attached to the chain 12 are also removed. These peeled substances are removed to the outside via the rotary valve 7. After rotating the chain 12 for a predetermined period of time, the motor 15 is stopped.
In this manner, the operation for removing deposits is performed every time a required period of time has elapsed during furnace operation. Further, the treated gas from which harmful components have been removed is discharged into the atmosphere through the discharge port 8 together with evaporated water.

Furthermore, although the suspended length of the chain extends to the connecting portion with the constricted portion 3 in the illustrated example, it may be extended further to the constricted portion 3 without any problem.
