The axially aligned tubular channels of the honeycomb carrier are coated with a catalytically active material such as platinum, rhodium, palladium, etc. and a heat-resistant material that provides a large surface area for the distribution of the catalytically active material. The high surface area heat resistant material is applied as a viscous slurry, such as finely divided gamma alumina. In the catalyst production process, from the point of view of cost and obtaining the desired level of catalytic performance, it is important to minimize the amount of slurry applied to the honeycomb carrier and to repeat the application when simultaneously applying high surface area materials and catalytically active materials. It is extremely important to be able to control the application process to produce consistent results.

とで反復性のある結果が得られる。(Prior Art) Various methods and devices for applying slurry to honeycomb carriers are known. For example, the US patent cylinder 3.5
According to No. 65,830, after a honeycomb carrier is immersed in a slurry, air is blown to remove the slurry and open the blocked passages. Such methods blow away the slurry, making it difficult to reuse the coating slurry. Next, JP-A-59
According to the alumina coating method for a honeycomb carrier disclosed in Japanese Patent No. 493140, after a fixed amount of slurry is applied, a vacuum pressure is applied to the honeycomb carrier to create a differential pressure on both end faces, thereby discharging excess slurry and clogging the honeycomb carrier. Open the passage. With this method, the coating slurry is collected in a vacuum tank, making it easy to reuse the coating slurry and providing excellent economic efficiency. Moreover, repeatable results can be obtained by applying a fixed amount of slurry.

担体の一端に大気圧の空気を与えることが必要である。(Problem to be Solved by the Invention) In the latter method, in order to apply a sufficient differential pressure to open the passage, atmospheric pressure air must be applied to one end of the honeycomb carrier in order to introduce an appropriate amount of air flow into the passage. It is necessary.

面に落下し通路を閉塞させるなど好ましくない。The inventor studied a method for guiding an appropriate amount of air from the slurry measuring section to the end face of the honeycomb carrier. However, with this method, the slurry adhering to the supply valve etc. tends to dry out, so if air is supplied after the slurry, the adhering slurry dries and solidifies, reducing the sealing performance of the supply valve and causing loss of repeatability in slurry quantification. Otherwise, the solidified slurry may fall onto the end face of the honeycomb carrier and clog the passage, which is undesirable.

ない。The inventor supplied slurry from a slurry meter to the upper end surface of the honeycomb carrier through a slurry injection device fixed to a connecting member that seals the outer circumferential wall of the end surface of the honeycomb carrier, and used a differential pressure between both end surfaces of the carrier. In an apparatus for applying slurry to a carrier, an attempt was made to separate the slurry measuring section from the slurry injection device and introduce air through this gap. However, when a slurry having a viscosity of several centipoise to several tens of centipoise is introduced, some of the slurry bounces off the end face of the honeycomb carrier and comes out through the gap between the slurry meter and the slurry injection device. The quantitative nature of the slurry is lost, and the slurry that comes out is likely to stick to surrounding equipment and solidify, making it difficult to collect and reuse the slurry and causing equipment failure. Furthermore, in order to uniformly apply the slurry to the honeycomb carrier, it is not preferable that the slurry meter outlet and the end face of the honeycomb carrier be separated by 40 cm or more.

The aim is to improve

ことを特徴とする。That is, the slurry injection device of the present invention injects slurry from an upper slurry meter onto the upper end surface of the honeycomb carrier, and uses the differential pressure between the both end surfaces of the honeycomb carrier into the tubular passages aligned in the axial direction of the honeycomb carrier. A slurry charging device used for applying slurry includes a cylindrical body whose inner shape is approximately the same as the cross-sectional shape of the honeycomb carrier, and a close wall that engages with a slurry meter at the top of the cylindrical body. The cylindrical body has an intake part on the side surface thereof that introduces enough air to remove the clogged slurry in the tubular passages of the honeycomb carrier, and the air taken in by this intake part changes direction two or more times. The honeycomb carrier is characterized in that it is provided with a structure in which it is supplied to the upper end surface of the honeycomb carrier.

ゴムを用いてもよい。The close wall used in this invention is preferably strong enough not to be drawn inward during depressurization treatment and flexible enough to bring the cylindrical body of the slurry charging device and slurry measuring device into close contact, such as NBRCR or SBR. Rubber such as may also be used.

とするのが好ましい。The intake part is bent at least twice so that the air taken in from the intake port on the side surface of the cylindrical body reaches the upper end surface of the honeycomb carrier so that the trajectory is not the same as the trajectory of the slurry droplets that bounced off the end surface of the honeycomb carrier. It has a structure that allows it to be supplied by changing direction. Such an intake part may have a shape with an intake port that opens upward, as in Example 1, which will be described later, or may have an intake port that opens on the side, as in Example 2, and has a horizontal air flow inside. It may also have a shape with a discharge port. In the former case, the bottom surface of the suction section is tilted inward and downward at an angle of 40° or more with respect to the horizontal direction, so that even slurry droplets of several hundred centipoise that have rebounded and adhered to the bottom surface of the suction section will slide off and be reapplied to the end surface of the honeycomb carrier. It is preferable that the

が好ましい。In the latter case, the slurry droplets that bounce back collide with the bottom surface of the suction section and fall, and even if the slurry droplets reach the surface, they fall due to the slope of the surface. Furthermore, the inventor has determined that the cross-sectional area is 67.9 to 12
0 cm" with 300 to 400 passages per square inch.
200 to 900 mm for applying slurry with centipoise viscosity and performing depressurization treatment to remove blockages in passages.
It has been found that purging with HzO is effective. In order to obtain the amount of air necessary for this purging, it is preferable that the intake section has an opening area of at least 10 cm2 or more.
