問題点が残されている。(Conventional technology and its problems) In bag filters used to remove soot dust, harmful gases, etc., it is necessary to prevent clogging of the filter cloth due to sticky dust, mist, etc. in the gas to be treated such as dust-containing gas, and to remove harmful components. For removal, a treatment method has been known in the past in which a pre-coating layer of pre-coating powder such as slaked lime, calcium carbonate, clay, activated carbon, etc. is formed as an adsorbent on the filter cloth surface of a bag filter. However, in this conventional method, powder is supplied into the gas to be treated at the inlet side of the gas to be treated, and the powder is attached to the gas by temporarily passing through the filter cloth surface. In a typical bottom inlet type bag filter in which the gas to be treated is introduced from the lower part of the filter cloth 21 as shown in Figure 2, when the diameter of the powder particles supplied into the gas to be treated becomes large, the powder is mixed with the gas to be treated. Without reaching the filter cloth surface, it falls directly into the hopper 23 at the bottom of the dust collection chamber 22, and as an example of this, commonly commercially available slaked lime powder with an average particle size of about 40 to 100μ is supplied into the gas to be treated. According to the results of an experiment in which the water was passed through the surface of the filter cloth 21 at a normal filtration speed, more than 70% of the supplied amount did not reach the surface of the filter cloth 21 and directly fell into the hopper 23. The utilization rate of powder is extremely low and uneconomical, and furthermore, in order to increase the utilization rate of powder with the above method, it is necessary to reduce the particle size of the powder or increase the filtration rate. However, it is not practical because it has no effect unless it is changed in units of several times to ten times, and
As shown in FIG. 3, in the case of a top inlet type bag filter in which the gas to be treated is introduced from the upper part of the filter cloth 24, the utilization rate of the powder to the filter cloth 24 is similar to that of the bottom inlet type described above under appropriate conditions. However, it still has the drawback of not reaching an economically sufficient utilization rate. Also,
JP-A-51-121866 discloses a technique for resupplying powder by returning it from a powder storage tank to a duct that sends it above a cylindrical filter cloth, which has fallen into a hopper. The powder supply air shown is designed to pass through the filter surface of the cylindrical filter cloth in the same way as the dust collection air, so the flow rate of the powder supply air is such that the cylindrical filter cloth will not be damaged. Therefore, the problem remains that it is difficult to precoat a uniform precoat powder layer over the entire surface of the filter cloth due to incomplete dispersion of the powder.

１内へ粉体を供給するようにしてもよい。(Example) Next, the method of the present invention will be explained in detail using the bag filter shown in FIG. 1 as an example. At the same time, a dust collection chamber of a bag filter is provided with an inlet duct 5 for supplying gas to be treated and an outlet duct 6 for discharging treated gas on one side, and has a hopper 7 at the bottom. On the other hand, there is a hopper 7 where fallen soot dust or powder accumulates.
A circulation duct 8 is provided, the ends of which are connected to an inlet pipe 10 whose ends are located slightly above the lower discharge port and above the upper partition plate 3, and a fan provided in the middle of the circulation duct 8; The operation of the gas circulation device 9 such as an ejector generates an airflow from the bottom to the top in the circulation duct 8, which is sucked in from the bottom of the dust collection chamber 1, passes through the circulation duct 8, and flows into the top of the dust collection chamber 1. and is adapted to generate a circulating gas flow which is circulated by 10
has one end in communication with the circulation duct 8 and the other end in communication with an air supply source or outlet duct 6 (not shown) to supply powder for precoating to the cylindrical filter cloth 2 together with air or treated gas into the dust collection chamber 1. This is an introduction pipe designed to feed the powder, and the supply device 11 for the pre-coat powder is installed in the middle, and during normal operation of such a bag filter, the inlet duct 5
The inlet damper 12 provided in the circulation duct 8 is opened, and the lower damper 13 and upper damper 14 of the circulation duct 8 are closed to prevent the gas to be treated and the removed soot and dust from entering the circulation duct 8. The gas to be treated is introduced into the dust collection chamber 1 through the inlet duct 5, passes through each cylindrical filter cloth 2 to remove dust, harmful gases, etc. from the gas to be treated, and is then transferred to the outlet duct 6 as clean gas.
Although filtration is performed by discharging the powder to the outside, if the powder is to adhere to the filter surface of the cylindrical filter cloth 2, the inlet damper 12 of the inlet duct 5 is closed to prevent the dust collection chamber 1 from being exposed. The introduction of the processing gas is stopped, and the dust adhering to the filter cloth surface and the dirty precoat layer that has been deposited in advance are removed by shaking, backwashing, etc., which are generally performed, and the filter cloth is installed at the bottom of the hopper 7. Discharge to the outside from the discharge device 15,
Next, if the lower damper 13 and upper damper 14 of the circulation duct 8 are opened and the gas circulation device 9 is activated, the inside of the circulation duct 8 is moved downward from the upper part of the dust collection chamber 1 through the cylindrical filter cloth 2 and the lower part of the hopper. A more upward airflow is generated, and a circulation path dedicated to precoating is formed that circulates and flows in the dust collection chamber 1 and the circulation duct 8 separately from the dust suction path. If the pre-coat powder is supplied at a predetermined ratio to the circulating gas flow circulating through the dedicated circulation path, and is allowed to join the circulating gas flow in a suspended state and introduced into the dust collection chamber 1, a portion of the combined gas will be While passing through the cylindrical filter cloth 2, the precoating powder is suspended by the suction force to the outlet duct 6 and adheres to the surface of the cylindrical filter cloth 2 to form a precoat layer. The remaining pre-coating powder that has fallen to the hopper 7 side without adhering to the filter cloth 2 surface is collected by the circulation gas flow sucked into the circulation duct 8 from below the dust collection chamber 1, and is passed through the circulation duct 8. It rises with the circulating gas flow and is again supplied to the filter cloth surface of the dust collection chamber 1. When the supply of a predetermined amount of powder for precoating is completed during repetition of such operation, the supply device 11
If the gas circulation device 9, etc. continues to operate for a while, the pre-coat powder in the dust collection chamber 1 will be repeatedly supplied to the cylindrical filter cloth 2 as described above, and most of it will be filtered out. When it adheres to the fabric surface and the desired precoat layer is formed in this way, the gas circulation device 9 is stopped to stop the circulation gas flow, and the introduction of air into the introduction pipe 10 is also stopped to remove the lower damper 13 and the upper damper. 14 is closed, and then the inlet damper 12 is opened to introduce the gas to be treated into the dust collection chamber 1, and normal operation is resumed. Although the introduction pipe 10 is connected above the circulation duct 8, it may be connected below the circulation duct 8 or directly into the dust collection chamber 1.
1 may be attached to a location other than the introduction pipe 10 to supply powder into the dust collection chamber 1.

である。(Effects of the Invention) As described above, the present invention provides a dedicated pre-coat circulation system that circulates from the upper part of the dust collection chamber 1 through the cylindrical filter cloth 2 and the lower part of the hopper to the upper part of the dust collection chamber 1 from the circulation duct 8. A route is formed separately from the dust collection route from the inlet duct 5 for supplying the gas to be treated through the cylindrical filter cloth 2 to the outlet duct 6 for discharging the treated gas, and the circulating gas flow circulates through this pre-coating dedicated circulation route. The pre-coat layer is formed on the filter cloth surface by the suction force from the outlet duct 6 generated in the dust suction path while the pre-coated powder is placed on the filter cloth 2 and passes through the inside of the cylindrical filter cloth 2. A uniform pre-coat layer can be formed on the entire surface of the filter cloth without damaging it, and the rate of adhesion of the pre-coated powder to the filter cloth surface can be increased to significantly improve the yield, and the particle size is particularly small. It is possible to use general coarse powder without using powder, and it is extremely effective and
This is a significant contribution to the industry as an economical method of supplying powder for pre-coating in bag filters.
