<Operation>
Operation | movement of the waste gas processing equipment 1 and the chemical | medical agent blowing apparatus 5 is demonstrated using FIG. 1 and FIG.

  As shown in FIG. 1, exhaust gas generated in a combustion facility (not shown) is reduced in temperature reducing device 2 to a processing temperature in bag filter 4 by cooling water. The temperature-reduced exhaust gas flows through the gas duct 3 and flows into the bag filter 4. At this time, in the gas duct 3, the medicine blown from the medicine blowing device 5 and the exhaust gas are mixed. Thereby, in the gas duct 3 and the bag filter 4, the acidic gas contained in the exhaust gas reacts with the drug, and the acidic gas is neutralized.

  In the bag filter 4, dust contained in the exhaust gas, reaction products during the neutralization treatment, and the like are removed by a filter cloth. The exhaust gas from the bag filter 4 is attracted by the induction fan 7 and discharged into the atmosphere via a chimney (not shown).

  As shown in FIG. 2, in the medicine blowing device 5, the air for transportation flows into the gas duct 3 through the transportation pipe 51 by the blower 53. The transport pipe 51 is supplied with a medicine from a quantitative feeder 56. As a result, the medicine is transferred through the transport pipe 51 by air and blown into the gas duct 3.

  An adhesion preventing agent is sprayed from the spray nozzle 61 to the transport pipe 51. Specifically, the anti-adhesive agent is supplied to the spray nozzle 61 by the pump 63. At the same time, compressed air is supplied to the spray nozzle 61 by the air compressor 64. In the spray nozzle 61, the adhesion preventing agent is mixed with compressed air, and the adhesion preventing agent is pressurized. As a result, the mist-like adhesion preventing agent is sprayed from the spray nozzle 61 together with the compressed air.

  The sprayed anti-adhesive agent is mixed with the air from the blower 53 in the transport pipe 51. The air containing the adhesion preventing agent flows through the transport pipe 51 and is mixed with the drug at the connection portion 58. At this time, for example, the particles of the anti-adhesive agent adhere to the slaked lime particles, and the slaked lime particles are coated with the anti-adhesive agent. As a result, slaked lime particles can be prevented from adhering to the inside of the transport pipe 51. A mixed fluid of air, a medicine and an anti-adhesion agent is blown into the gas duct 3 from the medicine blowing device 5.

<Effect>
The effects obtained by the exhaust gas treatment facility 1 and the chemical blowing device 5 are as follows.

(1)
In the medicine blowing device 5, the medicine supplied into the transport pipe 51 is sent to the gas duct 3 by the blower 53. At this time, the adhesion preventing agent is sprayed into the transport pipe 51 by the adhesion preventing agent supply device 60. For this reason, it can prevent that a chemical | medical agent adheres to the transport piping 51. FIG.

  Moreover, since the adhesion preventing agent is an alcohol aqueous solution, it is possible to prevent the adhesion of the drug at an inexpensive running cost.

(2)
In this case, the particles of the adhesion preventing agent can be made fine by the spray nozzle. Thereby, the adhesion preventing effect can be enhanced. In addition, since the spray nozzle 61 is a two-fluid nozzle, the spray state of the spray nozzle 61 can be improved by using compressed air, and the particles of the adhesion preventing agent can be made finer. Thereby, the adhesion preventing effect can be further enhanced.

(3)
In the medicine blowing device 5, the spray nozzle 61 is arranged on the upstream side of the connection portion 58 in the transport pipe 51. For this reason, it can prevent reliably that a chemical | medical agent adheres to the transport piping 51. FIG.

  Further, since the spray nozzle 61 is disposed on the downstream side of the blower 53 in the transport pipe 51, the adhesion preventing agent does not affect the blower 53.

(4)
The spray particle diameter of the spray nozzle 61 is 10 [μm] or less. For this reason, it becomes easy for the particles of the anti-adhesive agent to uniformly adhere to the particles of the drug, and the adhesion preventing effect is enhanced.

(5)
The supply amount of the adhesion preventing agent is in the range of 100 to 400 [weight ppm] with respect to the amount of the drug supplied from the drug supply device. For this reason, adhesion of a medicine can be prevented reliably.

(6)
As described above, in the exhaust gas treatment facility 1, it is possible to prevent the chemical from adhering to the transport pipe 51, and to stabilize the amount of chemical sprayed. Thereby, the performance of the exhaust gas treatment facility 1 can be improved.

[Second Embodiment]
In the first embodiment described above, slaked lime is used as an example of the medicine. Here, another embodiment will be described using a sodium-based drug whose main component is sodium bicarbonate as an example. The schematic block diagram of the chemical | medical agent blowing apparatus 105 which concerns on FIG. 3 at 2nd Embodiment is shown. In addition, about the same structure as 1st Embodiment, while using the same code | symbol, the detailed description is abbreviate | omitted.

<Configuration of drug blowing device>
As shown in FIG. 3, the medicine blowing device 105 mainly includes a transport pipe 151 connected to the gas duct 3, a medicine supply device 152, a medicine crusher 159, a blower 153 as a blower, and an adhesion preventing agent. It has the adhesion prevention agent supply apparatus 60 for supplying, and the control apparatus 154 which controls operation | movement of each apparatus.

  The drug supply device 152 includes a drug storage tank 155 for storing a drug and a quantitative supply machine 156 for supplying the stored drug to the drug crusher 159. The fixed amount feeder 156 is provided in the lower part of the medicine storage tank 155, and is connected to the first transport pipe 151a.

  The drug pulverizer 159 is an apparatus for pulverizing the drug supplied from the drug supply device 152 to the extent that it can be transported by air, and is connected to the quantitative supply device 156 by the first transport pipe 151a. Further, the second crushing pipe 151b is connected to the medicine crusher 159. The spray nozzle 61 of the anti-adhesive agent supply device 60 is provided in the second transport pipe 151b. That is, the spray nozzle 61 is disposed on the upstream side of the drug crusher 159.

  The inlets of the first transport pipe 151a and the second transport pipe 151b are open to the atmosphere. A first damper 157a is provided in the first transport pipe 151a. A second damper 157b is provided in the second transport pipe 151b. The air distribution of the first transport pipe 151a and the second transport pipe 151b is adjusted by the first damper 157a and the second damper 157b. For example, the amount of air is adjusted by both dampers 157a and 157b so that the amount of air flowing through the second transport pipe 151b is larger than the amount of air flowing through the first transport pipe 151a.

  The blower 53 is a device that forms a flow of air for transporting the medicine, and is disposed on the downstream side of the medicine crusher 159. The suction side of the blower 153 is connected to the drug crusher 159 by a third transport pipe 151c, and the discharge side of the blower 153 is connected to the gas duct 3 by a fourth transport pipe 151d.

<Operation>
As shown in FIG. 3, in the medicine blowing device 105, the air flow for transportation is formed by the blower 153. Specifically, air is sucked from the inlet of the second transport pipe 151b, and an amount of air corresponding to the opening degree of the first damper 157a and the second damper 157b flows into the first transport pipe 151a and the second transport pipe 151b. .

  The air from the first transport pipe 151 a flows into the medicine crusher 159 together with the medicine supplied from the fixed amount feeder 156. On the other hand, the air from the second transport pipe 151 b flows into the drug crusher 159 together with the adhesion preventing agent sprayed from the spray nozzle 61 of the adhesion preventing agent supply device 60. That is, the transport air, the drug, and the adhesion preventing agent flow into the drug pulverizer 159.

  In the drug crusher 159, the drug is finely pulverized in order to increase the reaction efficiency with the acid gas. At this time, since the adhesion preventing agent flows through the inside of the drug crusher 159, it is possible to prevent the drug from adhering to the drug crusher 159. The pulverized drug is discharged from the drug pulverizer 159 together with the transport air and the anti-adhesive agent and sucked into the blower 153. In the blower 153, the transport air, the medicine and the anti-adhesion agent are mixed and discharged. In this way, the medicine is blown into the gas duct 3.

  In this case, since the blower 153 is disposed on the downstream side of the fixed amount feeder 156 and the medicine crusher 159, there is a possibility that the medicine adheres to the blower 153. However, since the adhesion preventing agent is supplied by the spray nozzle 61 on the upstream side of the blower 153 (more specifically, on the upstream side of the drug crusher 159), it is possible to prevent the drug from adhering to the inside of the blower 153, Abnormal vibration of the blower 153 can be prevented. Moreover, it can prevent that a chemical | medical agent adheres inside the chemical | medical agent grinder 159 and the transport piping 51. FIG.

For example, when the spray nozzle 61 is disposed on the upstream side (suction side) of the blower 53 or when the spray nozzle 61 is disposed on the downstream side of the connection portion 58, the transport nozzle 51 Can prevent the adhesion of drugs.

  In the second embodiment described above, the spray nozzle 61 is disposed on the upstream side of the drug crusher 159. However, the arrangement of the spray nozzle 61 is not limited to this. For example, even when the spray nozzle 61 is disposed between the drug pulverizer 159 and the blower 153, adhesion of the drug to the blower 153 and the transport pipe 151 can be prevented. Further, even when the spray nozzle 61 is disposed on the downstream side of the blower 153, it is possible to prevent the drug from adhering to the transport pipe 151.

(5)
In the above-described embodiment, the spray nozzle 61 is a two-fluid nozzle. However, the type of the spray nozzle 61 is not limited to two fluids. For example, when the air temperature for transportation is high (for example, when using a recirculated gas obtained by circulating a part of the exhaust gas, the temperature is about 160 degrees) The spray nozzle 61 may be a single fluid nozzle. In this case, the air compressor 64 becomes unnecessary.
