Description of the invention (I) The present invention relates to a structure of a ventilation system. The trench has a duct. Its content is a hollow filter body, such as a filter fiber that can produce a high 1 P leather from M The bag-shaped filter body is made, and the open end of the passing body is sealingly connected to the walls of the duct: | The ventilation system typically includes a central air treatment unit and fans, whose function is to supply air through the duct And exhaust (this is what the duct wants). The processed air is distributed to the openings in the duct system, so that the indoor air can be exchanged at a predetermined flow rate in the room M, and such things related to the ventilation system. These openings have ribs for the devices to function separately. K blows air into the relevant room and removes the old gas from then on. These devices are also equipped with adjustment mechanisms that can be set to deliver and remove the exact amount of air in and out of these rooms. Those who are familiar with this technology must be familiar with the problems associated with such adjustment mechanisms. As the airflow propulsion method, traditionally, a low-pressure differential pressure is used between the room and the duct, and part of it is also based on the economic aspect of Kalu: The conventional method of controlling the supply airflow and exhaust airflow by the rib low pressure difference is practical It is difficult to be satisfied, and a satisfactory result cannot be obtained, even if there are professionals who are present to assist. A result that could have been more satisfactory was not sufficient because of time-consuming * That is, when expanding the system, the entire system needs to be adjusted or rotated to adjust the system. To facilitate the adjustment of the system, a constant flow device has been developed, which The system can also maintain a constant air flow when making changes. However, these devices require a higher pressure difference and a higher energy input than the previous case-3-This paper standard is applicable to the Chinese National Standard (CNS) Α4 specification (210Χ 297 mm) (please read the notes on the back first Please fill out this page again.)--1T Printed by the Employees Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy Printed A7 B7 by the Employees Consumer Cooperative of the Central Bureau of Economics of the Ministry of Economy V. Description of the invention (V), and it still produces unacceptable sound , It must be inserted into the ventilation. The sound absorber in the system plus M attenuation. Each of these devices suffers from high costs, although the total cost will be reduced by avoiding the use of professionals to perform the aforementioned system adjustments. The Μ pressure difference is about 20 OPa, and a Μ stable air flow can be obtained in the holes of the duct, even when the duct system is expanded. The condition for this is that the pressure drop caused by the air flowing through the system is much lower than the pressure difference. This pressure drop becomes basically constant throughout the system. This solution is ideal. If it does not produce sound, it needs to include a complicated sound absorber. However, the desired bass intensity can be obtained in many different ways. For example > Bass strength can be effectively reduced by adding rib filter fiber plus M, because it can produce completely silent pressure reduction. This type of fiber has not previously been used with R added for the purpose of deliberately producing a relatively high pressure drop: however, this type of fiber has a highly beneficial second effectiveness. For example, it can improve the quality of air and the environment. When using a suitable filter material, such as F 8 5 (EU 7), the catheter system will be dust-free, thereby eliminating the need to clean the system and protecting it from being carried on large primary particles The harm of allergens, bacteria and even viruses "It is not difficult to see that in order to achieve the desired balance in this system, there is a problem. That is, a large number of filters are required to generate different pressure drops from each other: Combined with high pressure drop; 1 body to solve the aforementioned air balance problem.

Description of the invention (>) According to the present invention, is this purpose false? #It is achieved by adding K to the air flow in the balance system duct, which is specifically to throttle or ban the volume of air flow in each body. The volume of the filter body can be throttled or forbidden after the filter body is arranged, and it is best to implement by adding a filter adjustment line or an equivalent device to the bottom of the filter body, by which The bottom of the filter body can be oiled to the desired length of the filter body, that is, to the extent required to obtain the desired air flow: Such a filter body is adjusted to benefit a significant fact, that is, when it is aided by sleeves. When the filter body is folded in half at the bottom of the body, the air flow rate decreases almost linearly with the decrease of the filter body length: by the throttle mechanism of the rib machine, a small part of the throttle effect of the filter body can be obtained. The other case is that, by setting a rod at the bottom of the filter body and turning or twisting the rod M at an appropriate angle with respect to the open end of the filter body, a mutual effect can be obtained. Naturally, the effective length of the filter body can also be shortened by a rib-tightening member or the like. For this adjustment, it is best to use a filter body equipped with the air supply device, in which case the full length of the filter body is easy to reach.

Description of the invention (f) The bottom 7 of the filter is a filter adjustment line 8 < it spans the arms 10 on the collar 6 Carrying stalk 9: The movement of the filter body is full of points with the auxiliary line 1]. The bottom 7 of the filter body indicated by 3 is passed; the body adjustment line 8 is drawn into the body of the filter body * the line is tightly Fishing in a slot 12 on the wall of the duct: the air flow is shown by the medicine head i 3, and the magnitude of the air flow at different lengths of the body is shown in the fourth figure 1 although the ; The body 3 is entirely located in the path of the air flow, but the air flow is almost proportional to the shortening of the length of the filter body. A relatively accurate adjustment of the air flow rate can be achieved by observing the mark 14 on the line 8: The second figure shows another embodiment in which a filter body adjustment rod 2 Ο Μ end is connected to a filter body 3 Bottom 7. The other end of the rod 20 is provided with a grip 22 and can be clamped into a recess 23 of an annular cross member 24. The rod 20 and the filter body can be rotated to a certain degree, which allows the desired air flow to pass through the filter body, after which the rod is pressed into the recess 23: the third image shows an opening connected to an air supply port And enter the bag filter 3 in the room. The filter body can be adjusted with M to provide the desired air flow. The method is to first move a pair of cross members 31 to the opening α along the glaze quotient of the filter body, and identify the opposite side of the filter body 3 The transverse structure is clamped together, so that the effective length of the filter body is reduced, and at the same time, the nitrogen flow through the opening 30 is stopped to stop the movement of the transverse member, and then the transverse member is firmly screwed in for Get the correct location of the required air flow. The filter body is then equipped with M-can be easily removed to facilitate the change of the protective cover 32 of the extinction body.

Only pull the wire 8 ^ so that the German body is shortened from 4 0 cni to 10 cm, and the air flow close to 3 0 0 m 3 / h can be reduced to more than 10 0 m3 / h > The latter half is actually linear. It is understood that the present invention is not limited to the described and illustrated embodiments, but is within the scope of the invention defined by the following patent applications, and can be modified in various ways. For example, the filter body can be shortened by rolling up from the bottom end and locking the rolled portion of the filter body in a suitable manner (for example, by a rib-stapler). The corresponding reduction in the effective surface area can be achieved by adding a κ to the appropriate displacement of a ring along the extinction body. Those who operate the mechanisms shown in Figures 1 and 2 can also drive motors. The shape structure outside the body and its bottom can also be changed by adding K in different ways.
