本発明は、高濃度の含じんガスのみを有効に抽気し、小

クロン集じん装置に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a cyclone collection system with high collection efficiency that effectively extracts only highly concentrated dust-containing gas and collects the dust with a small dust collector. This relates to dust equipment.

もにサイクロン外に排出される。Conventionally, there has been a cyclone that has an inner cylinder hanging down inside the upper part of the outer cylinder, introduces dust-containing gas from the upper part of the outer cylinder, extracts dust from the lower part of the outer cylinder, and discharges the dust-removal gas from the inner cylinder. Generally used. In this conventional cyclone, dust that is not collected by the cyclone is discharged from the cyclone together with the exhaust gas.
一方、サイクロン出口管内には旋回流が残存し、ダスト

る。On the other hand, a swirling flow remains in the cyclone outlet pipe, and the dust settles and separates on the wall soil of the outlet pipe, so that most of the dust discharged with the exhaust gas collects near the wall of the outlet pipe.

スト濃度は３００ｇ／Ｎ ｎ？にもなる。FIG. 5 shows an example of dust distribution inside the cyclone outlet pipe. That is, the outlet pipe diameter is D1 and the average dust concentration is 1008/N n? Then, dust will collect on the inner wall of the outlet pipe to a depth of about 0.8D, and the maximum dust concentration on the pipe wall will be 300g/N n? It also becomes.

行、１５２頁参照）。As one method of collecting dust in the cyclone exhaust by utilizing the movement of dust in the outlet pipe, as shown in Figs. 6 and 7, a small A method of attaching a cyclone (child cyclone) 3 is known (see "Dust Collector" (new edition) edited by Kou Iitani, published by Nikkan Kogyo Shimbun on January 10, 1961, p. 152).

３に送られるガス中のダスト濃度が低下し、全体として
ダストの捕集効率の上昇があまり見られなかった。However, with the parent-child cyclone described above, it is difficult to extract only high-concentration gas containing gas, so the dust concentration in the gas sent to the child cyclone 3 decreases, and the overall dust collection efficiency does not increase much. I couldn't see it.

The outlet pipe of the parent cyclone has a double cylindrical structure to effectively extract only high-concentration gas containing gas and collect it in a dust collector such as a child cyclone, increasing the overall collection efficiency. The purpose of this invention is to provide a cyclone dust collector with

１３．１４はダスト抜出口である。[Means and effects for solving the problems] The cyclone dust collector of the present invention will be described with reference to FIGS. 1 to 3. A small inner cylinder 5 is further attached to the gas discharge side of the inner cylinder 4.
are arranged concentrically to form a double cylindrical structure, a gas discharge passage 6 is connected to this small inner cylinder 5, and one or more small cyclones (child cyclones) are connected to the peripheral edge of the inner cylinder 4 via a small duct 7.
, a leaflet duster 8 such as a dust chamber is connected. The gas discharge passage 10 of the leaflet duster 8 is connected to the gas discharge passage 6 of the parent cyclone 1 either directly or via an induced fan 11 . 12 is a gas containing rod duct,
13 and 14 are dust extraction ports.

などの小葉じん器へ送り込まれる。The size of the small inner cylinder 5 attached to the inside of the inner cylinder 4 (outlet pipe) is made to have an inner diameter of 80 to 85% of the inner diameter of the inner cylinder 4. In this way, if the exhaust air between the inner cylinder 4 and the small inner cylinder 5 is extracted to the small leaf duster 8 such as a child cyclone, 70 to 80% of the dust contained in the exhaust air will be removed from the small leaf duster 8 such as a child cyclone. It is sent to the leaf duster.

量は半減する。On the other hand, the collection efficiency of the leaf duster 8 varies depending on the type of leaf duster, but it is thought that an efficiency of at least 70 to 75% can be obtained. Therefore, the collection rate for the dust discharged from the parent cyclone 1 equipped with the leaf duster 8 such as the child cyclone is approximately 0 to 80% of the amount of dust in the parent cyclone exhaust introduced into the leaf duster 8 such as the child cyclone. Since the collection efficiency of small leaf dusters such as child cyclones is near 0 to 75%, it becomes 49 to 60% multiplied by these values.
When the cyclone dust collector of the present invention is used, the amount of dust discharged is halved compared to when a conventional cyclone is used.

It passes through a cyclone (not shown), a C2 cyclone 15, and a C3 cyclone 16 in this order, and is sent to the final stage cyclone (C, cyclone 17) while exchanging heat with the raw material sent from the upper stage cyclone. FIG. 4 shows a C4 cyclone 17 employing the cyclone dust collection device of the present invention. The gas that has undergone heat exchange in the C4 cyclone 17 passes from the small inner cylinder 5 of the C4 cyclone through the gas discharge path 6 to S
The P fan 18 discharges it to the outside of the yarn.

ることができる。At this time, in the conventional cyclone shown in FIGS. 6 and 7, the heated raw material and gas are not completely separated,
Approximately 100g/Nrd of raw material was discharged. The heated raw material discharged outside the system together with this exhaust gas causes a deterioration in the heat consumption of the firing system and S
This resulted in worsening of P fan power consumption. However, if the cyclone dust collector of the present invention is used, the amount of raw materials discharged outside the system will be significantly reduced by 40 to 50 g/N n? ), heat consumption and power consumption are reduced, and operating costs can be reduced.

This has the effect of greatly improving the dust collection efficiency as a whole.
