Abstract

PURPOSE:To reduce air passing resistance by automatically and rapidly removing the greater part of dust separated at the surface of a partition wall, by withdrawing dust-containing gas separated by the partition wall to recirculate the same to the inlet part of the partition wall. CONSTITUTION:A gas intake pipe 8 is penetrated into a hopper 5 in order to withdraw dust-containing gas from the lower parts of porous tubular bodies 2. The intake pipe 8 is connected to the suction port of a blower 9 and further connected to a dust-containing gas introducing pipe 11 connected to a dust- containing gas introducing port 4 from the emitting port of the blower 9 through a recirculation pipe 10. By operating the recirculation route of dust-containing gas, dust-containing gas also flows in the lower part of the porous tubular bodies 2 and, therefore, the dust adhered to the lower inner surface of each porous tubular body 2 is also easily fallen in the hopper 5. It is effective that the recirculation amount of dust-containing gas is adjusted to 5-25% of the feed-in amount of dust-containing gas.

アを設けである。FIG. 1 shows a conventionally proposed device for removing dust from dust-containing gas using a porous pipe body. A plurality of porous tube bodies 2 having air permeability are vertically arranged side by side, supported at both ends by tube sheets 3, and housed in the can body 1. A dust-containing gas inlet 4 is attached to the upper lid of the can body 1, and a hopper 5 for retaining separated dust is attached to the lower side of the can body 1. A dust outlet 6 equipped with a valve for removing dust is provided on the lower side of the hopper 5. The body of the can body 1 is provided with a clean gas extraction lower.

して通気抵抗を少なくすることが必要である。When the dust-containing gas is supplied through the inlet 4, the dust-containing gas enters each porous tube 2, and due to the pressure difference between the inside and outside of the porous tube 2, the clean gas flows into the tube wall of the porous tube 2. through the porous tube body 2
It goes outside and is taken out of the can body 1 through the clean gas take-out lower. On the other hand, the dust that is blocked from passing by the inner wall of the porous tube body 2 is caused to fall by the kinetic energy of the downward flow of the dust-containing gas, and the dust aggregates with each other and is attracted by its own gravity. It falls and is stored in the hopper 5. The dust in the hopper 5 is intermittently taken out through the dust outlet 6. During this time, part of the dust coagulates and adheres to the vicinity of the inner wall to form an overlayer of dust, and most of the dust falls, and the dust-containing gas is constantly removed. Of course, if you repeatedly remove dust,
Since the amount of dust clogging the holes on the inner wall of the porous tube body 2 increases, it is necessary to remove the dust by backwashing or the like after use for a certain period of time to reduce ventilation resistance.

通気抵抗が増加して通気機能を実質的に失なってくる。One of the features of such a dust removal device is that it can process a relatively large amount of dust-containing gas considering its installation area, and although it varies depending on the dust removal device specifications and operating conditions, it is generally used at the inlet of the porous tube body 2. The flow rate of the dust-containing gas is 15 to 15 m7 seconds, and the kinetic energy of the dust-containing gas is large in the upper part of the porous tube 2, so that the separated dust adhering to the inner wall can easily fall. However, since the clean gas flows out through the porous pipe body 2, the flow velocity of the dust-containing gas decreases as it goes downward in the pipe, and since the dust outlet 6 is usually open, the porous At the lower end of the tube body 2, the flow velocity of the dust-containing gas becomes zero. Therefore, if we also consider that the kinetic energy of the dust-containing gas is zero, and that the kinetic energy of the dust-containing gas also contributes greatly to mutual agglomeration of dust, it is assumed that at the lower part of the porous tube 2, Dust adhering to the inner wall is difficult to fall off, and the ventilation resistance in this area increases and the ventilation function is essentially lost.

これが逐次上方に波及していき、全体としての通気機能

This dust removal method is characterized in that dust-containing gas is extracted from the lower part of the partition wall and circulated to the upper part of the partition wall.

ちる。In the apparatus shown in FIG. 2, a gas suction pipe 8 enters the hopper 5 in order to extract dust-containing gas from the lower part of the porous tube body 2. In the case where a large number of porous tubes 2 are installed in parallel as in this example, the position of the tip of the suction tube 8 and the It is necessary to consider the shape. In addition, it is necessary to take measures to prevent as much as possible from inhaling the separated and falling dust. The suction pipe 8 is connected to the suction port of the blower 9. The discharge port of the blower 9 is connected to a circulation pipe 10 , and the tip of the circulation pipe 10 is connected to a dust-containing gas introduction pipe 11 that is connected to the dust-containing gas introduction port 4 . Although not shown in the drawings, the circulation pipe 10 and the suction pipe 8 are provided with a pulp and a meter for adjusting the flow rate and pressure of the dust-containing gas to be circulated.

前述の如く、この装置において含塵ガスの循環系路を作

Since the dust-containing gas flows also in the lower part of the porous tube body 2, the dust adhering to the inner surface of the lower part of the porous tube body 2 easily melts and falls into the pipe 5. The dust-containing gas sucked through the suction pipe 8 is mixed with new dust-containing gas because the circulation pipe 10 is connected to the introduction pipe 11, and is sent into the porous tube body 2 again. .

な集塵率の維持に有効で望ましい。As the amount of dust-containing gas sucked into the suction pipe 8 increases, the gas flow velocity within the porous tube body 2 increases, and more dust adhering to the inner wall of the porous tube body 2 falls. is,
The ventilation resistance of the porous tube body 2 is reduced, the amount of clean gas taken out is increased, and the gas flow rate inside the tube 2 is increased. This will cause turbulence and the separated dust will be sucked in at the same time.
In addition, a dust filtration layer that is preferable for maintaining an appropriate dust collection rate is not formed, which is undesirable. Moreover, the power of the blower 9 is wasted. In order to drop the dust adhering inside the porous tube 2, it is generally desirable that the flow velocity of the dust-containing gas in the lower part of the porous tube 2 is 13 m/sec or more. Furthermore, if the flow velocity of the dust-containing gas is increased from El 3 m/sec to 7 seconds, the amount of falling dust will also increase, but if it exceeds 4 m/sec, the above-mentioned problems will occur, so the gas flow velocity should be reduced to 0. It is particularly desirable to maintain the velocity between .5 and 4 m/sec. In addition, the gas flow rate at the lower part of the porous tube body 2 is set to a3
The circulation rate of dust-containing gas to maintain the speed of ~4m/sec is 5 times the amount of dust-containing gas fed into this device (same as the amount of clean gas obtained).
~25% is effective and desirable for reducing power costs and maintaining an appropriate dust collection rate.

φ型でかつ簡便な除塵設備を第３図、第４図に示す。Since it is desirable that the dust separated and fallen into the circulating dust-containing gum is not entrained, the position and shape of the tip of the suction tube 8 are taken into consideration as described above.
A dust removal equipment using inertia or centrifugal force is installed in the middle of the process, and the dust-containing gas is extracted through the equipment. This makes it possible to collect dust in the dust-containing gas and part or ephemeral part of the dust that is sucked in after separation and fall, and reduces the dust load when it is circulated into the upper part of the porous tube body 2. It can be reduced. Such a φ-type and simple dust removal equipment is shown in FIGS. 3 and 4.

好ましい。In the above description, a porous tube was used as an example of the porous partition wall, but a plate-shaped body or the like may be used instead of the tube. The partition walls can be made of various materials such as ceramics, glass, carbon steel, and sintered metals, but ceramics are generally preferred because they have excellent heat resistance, thermal shock resistance, and corrosion resistance.

Dust-containing gases are discharged at temperatures that reach even higher temperatures. To recover heat from such dust-containing gas, it is necessary to remove dust to produce clean gas, but conventional dust removal methods such as bag filters and electric precipitators cannot be applied to such high-temperature dust-containing gas. It was something. One of the features of the method of the present invention is that it can be applied to such high-temperature dust-containing gas.

値が大である。The dust removal method of the present invention is configured and functions as described above,
By maintaining the flow velocity of the metal gas in the lower part of the porous partition at a desired value, the dust adhering to the lower part of the partition can be smoothly peeled off and fallen, and the ventilation resistance of the partition can be reduced. Therefore, the interval between backwashing and other treatments can be lengthened, and the operating rate of the dust removal device can be improved. Furthermore, if the dust-containing gas is simply extracted, the extracted dust-containing gas will still contain dust, so in order to recover heat from now on, it will be necessary to perform dust removal treatment that involves a considerable amount of heat loss. The method of the invention simply circulates the dust-containing gas above the partition wall, without requiring any special equipment for such treatment or the associated installation space, and with the same heat loss as with new dust-containing gas. It is possible to reduce dust and remove dust efficiently. Therefore, the dust removal method of the present invention has great industrial utility value.
