Description

[Detailed explanation of the invention] (a) Field of industrial use This invention is an air conditioner for a textile factory, and when the factory air is circulated, a large amount of dust ( This relates to a device that removes wind cloth, glue scum, etc.) and supplies clean air into the factory.

(b) Conventional technology Conventionally, rotary air dust removers have been used to remove dust from the circulating air of air conditioners in textile factories. In order to remove it, a suction method using air current was used.

(c) Problems to be solved by the invention The conventionally used rotary air dust remover is
Since the material is made of cloth, dust attached to the material is removed by suction using airflow.
Dust could not be completely removed, causing clogging of the material and reducing the amount of air passing through, reducing the efficiency of the air conditioner. Particularly in textile factories, glue is used for the warp threads for weaving, and the glue is scattered into the air, and a large amount of the glue is contained in the return air for air conditioning. In addition, in textile factories with high humidity, the adhesive material becomes viscous due to moisture content, and sticks to the cloth material along with dust, making it extremely difficult to remove dust from the surface of the cloth material using air flow. was. Therefore, it is necessary to frequently replace the fabric lumber, which increases labor and expense, and the amount of air blown before and after changing the material changes significantly, causing large fluctuations in temperature and humidity within the factory, which poses a major problem for factory operations. Ta.

(d) Means for solving the problem The device of the present invention consists of a rotating drum with a hollow axis S positioned almost horizontally inside a dust removal chamber A equipped with an air intake port _A1 and an air discharge port _A2 . 1 is covered with a wire mesh 3, one end surface 4 of which is closed and the other end surface 5 is opened to communicate with the air discharge port _A2 , and pressurized through the hollow passage of the hollow shaft center S. The introduced flowing water W is caused to fall into a pipe 6 having substantially the same length as the rotating drum 1, which is positioned parallel to and facing the lowest circumferential surface of the rotating drum 1.
The flowing water W is ejected from a plurality of spray nozzles 7 installed on the lower surface of the pipe 6 toward the lowest peripheral surface of the rotating drum 1 when the rotating drum 1 rotates, and when the rotating drum 1 is stopped, the flowing water W is ejected. This is an intermittent water washing type air dust removal device in which the ejection is stopped and this rotation and stop are intermittently repeated. The intermittent water washing type air dust removal device according to the present invention (hereinafter referred to as "the device of the present invention") will be explained in detail below.

Figure 1 is a simplified plan view of the main parts of the device of the present invention, Figure 2 is a simplified elevational view of the main parts, Figure 3 is a simplified side view of the main parts, and Figure 4 is an explanation showing the state of connection and arrangement with the air conditioner. It is a diagram.

Fig. 4 A shows a dust removal chamber containing the device of the present invention, B shows an air conditioner, F ₁ shows an intake fan, F ₂ shows a blower fan, D ₁ shows a return air duct connecting the factory and the dust removal room,
_D2 is the ventilation duct that connects the air conditioner and the factory, and each is airtightly connected, so
Return air R・A from the factory enters the dust removal chamber A through the return air duct D ₁ and the air intake port A ₁ by the suction force of the intake fan F ₁ , and enters the rotating drum 1 of the device of the present invention in the direction of the arrow. . At this time, the wire mesh 3 covering the circumferential surface ₂ of the rotating drum 1 removes dust contained in the return air R.A, and turns it into clean air C.A. Juan F ₁ , air conditioner B,
Fresh air FA is sent to the factory through a blower fan F ₂ and a blower duct D ₂ .

As shown in FIG. 2, the open end surface 5 of the rotating drum 1
The air outlet of the dust removal chamber has a diameter slightly smaller than that of the
When the open end surface 5 is communicated with A ₂ , since the other end surface 4 of the rotating drum 1 is closed, the airflow flows through the wire mesh 3 covering the circumferential surface 2 of the rotating drum 1 as shown by the arrow. As the air passes through the air, all the dust contained in the air adheres to the three surfaces of the wire mesh, and the passed air is introduced into the intake fan F ₁ and the air conditioner B through the air outlet A ₂ .

Pressurized running water W is introduced into the hollow passage of the hollow shaft center S of the rotating drum 1, and the running water W is positioned parallel to the lowest circumferential surface of the rotating drum 1, as shown in the figure, on both end surfaces 4. , 5 is dropped onto a pipe 6 whose length is approximately the same as the width of the cylinder between the pipes 6 and 5, and sprayed from a plurality of spray nozzles 7 attached to the bottom surface of the pipe 6 toward the lowest circumferential surface. Running water W
Therefore, the dust adhering to the wire mesh surface 3 is peeled off from the wire mesh surface 3 and falls into the water receiver 8 provided under the rotating drum 1 along with the running water W, and the wire mesh surface 3 of the rotating drum 1 is cleaned. . The rotating drum 1 is intermittently driven by a deceleration motor M in a known manner, and the water W is ejected from the spray nozzle 7 in synchronization with the driving of the rotating drum 1.

A rubber slit band 9 is attached to the open end surface 5 of the rotary drum 1 to maintain airtightness with the air outlet _A2 and to smoothly drive the rotary drum 1. The dust and water that have fallen into the water receiver 8 are discharged to the outside of the dust removal chamber A through the discharge pipe 10, the water and the dust are separated by a known method, and the dust is automatically stored in a predetermined storage container.

The wire mesh used is made of corrosion-resistant stainless steel or synthetic resin.

(E) Effect Since the device of the present invention has the above configuration,
Return air R・A from the factory is introduced into the dust removal chamber A from the air intake port A ₁ through the return air duct D ₁ .
Since the dust removal chamber A is airtight, the return air R.A passes through the wire mesh 3 as a material on the outer circumferential surface of the rotating drum 1, passes through the air outlet A ₂ , the intake fan F ₁ , and enters the air conditioner B. be introduced. Wire mesh 3 of rotating drum 1
The dust contained in the return air R・A is filtered and accumulated on the surface, and only the purified air C・A passes through the intake fan F ₁ and the air conditioner B and is adjusted to a predetermined temperature and humidity. Then, fresh air F.A is supplied by blower fan _F2.
The air will be blown to the factory through the air duct _D2 . The rotary drum 1 is intermittently driven by a deceleration motor M in a 1/4 to 1/6 rotation in the usual manner, but at the same time as it starts rotating, a powerful jet of water W is ejected from the spray nozzle 7. Therefore, during the rotation, the dust adhering to the outer surface of the lowest circumference of the rotary drum 1 is peeled off together with the running water W, and the dust is removed from the water receiver 8.
to fall. The rotating drum 1 slowly rotates from 1/4 to 1/6 of a turn, removes dust adhering to the wire mesh 3 surface from 1/4 to 1/6 of the circumferential surface 2, and then stops. At the same time as the rotating drum 1 stops, the jetting of the running water W also stops. After about 10 minutes, the rotating drum 1 starts rotating again, and the spray nozzle 7 sprays a powerful stream of water W.
Wash 1/4 to 1/6 of the circumference and stop. By repeating rotation (cleaning) and stopping as described above, the cleaned wire mesh 3 on the circumferential surface makes one revolution and returns to the lowest circumferential position again. Come and wash again and repeat. The dust exfoliated with the running water W falls into the water receiver 8,
It is discharged to the outside of the dust removal chamber A through the discharge pipe 10,
Water and dust are separated by a normal method, and the dust is automatically stored in a predetermined storage container.

In particular, the glue used in weaving factories is water-soluble, so by using water, the wire mesh 3
The pressurized jet water W can be easily peeled off from the
Therefore, the wire mesh 3 is completely cleaned, and a constant amount of air can always be obtained.

Immediately after cleaning, the three surfaces of the wire mesh of the rotating drum 1 are wet, making it easier for dust to adhere to them. Even if the mesh size of the wire mesh is larger than that of conventional cloth materials, the dust removal effect can be improved. Because of the air
Even if the three sides of the wire mesh are dry, the fibers attached to the mesh become material and increase the dust removal effect, so a large amount of passing air can be obtained compared to a dust removal device using conventional cloth material.

(f) Examples An example in a textile factory is shown below.

The external dimensions of the rotating drum of the device of this invention installed for air conditioner B with a processing air volume of 1500M ³ /min are:
2000mmφ×2200mmL, reduction motor M is 0.1kw×
1.5RPM, wire mesh 3 as material is SUS304
(100MESH), spray pump is 1.5kw x 20m x
It is 120/min.

The period of rotation of the rotating drum 1 and the spouting of flowing water is approximately 1
minute, during which the rotating drum 1 rotates 1/5 and stops.
After about 11 minutes, rotating drum 1 rotates 1/5 again,
A jet of running water will begin for 1 minute. By repeating this cycle of rotation and stopping for 12 minutes, the rotating drum 1 rotates once in about 1 hour, and the wire mesh 3 as a material
Dust can be removed from the surface.

By using this device, clogging of materials is eliminated, and while with conventional rotary air dust removers the average static pressure was 19 mmAq and the maximum static pressure was 25 mmAq, with the device of this invention, the average static pressure was 13 mmAq and the maximum static pressure was 15 mmAq. We were able to reduce the structure and installation area of the dust removal device by approximately 50%. In particular, with the conventional rotary air dust removal equipment used in textile factories, the material had to be replaced every four months due to clogging of the material, but by installing the device of this invention, there is no need to replace the material. We were able to eliminate personnel costs and expenses. In addition, with conventional rotary air dust removers, it is necessary to manually store the captured dust in the storage container again, which is unhygienic as the dust scatters and is disliked by workers. By using water, the device can automatically collect only dust, and does not require human intervention.Since the dust becomes wet and semi-solid, it is hygienic and does not scatter.

Also, because of the intermittent drive, the amount of water used can be reduced to 1/10 of that of continuous rotation.

(G) Effects of the invention Since the device of the present invention has the above configuration,
As a dust removal device when circulating the air within the factory in an air conditioner at a textile factory, it eliminates clogging of materials, makes it possible to supply a stable amount of air, and maintains a constant temperature and humidity inside the factory. In addition to greatly improving machine efficiency, it also eliminates the need to replace materials, helping to reduce labor costs and expenses, and improves air conditioning by increasing the amount of air passing through compared to conventional dust removal equipment. The structure and installation area of the device could be greatly reduced, and the power cost of the air conditioner could be reduced.

In addition, since the rotating drum is rotated intermittently and the water is spouted intermittently, the jet of water can be concentrated in localized areas, making it easier to remove dust and improve the quality of the material. It is possible to completely clean the water, and since water is spouted intermittently, the amount of water used can be greatly reduced.

Particularly in textile factories, the problem of glue material adhering dust to the surface of the material, causing clogging, has been completely solved by the device of the present invention, which uses running water.

In addition, since the captured dust is automatically stored in a storage container, no human intervention is required, and the work environment is improved by eliminating hygienic operations that are disliked by workers.

That is, the device of the present invention is an extremely useful intermittent water washing type air dust removal device that has many advantages as described above.
