Description of the invention (>) > The adsorption column is then contained in a tank or sleeve (such as active column and zeolite). Many production equipment for semi-conducting components will collect pipelines The connection is also known. Because some of the lotus production processes in the quail production equipment do not occur simultaneously, a mixed gas mixture will form in the collection pipeline, and some of its components will repulse each other and form new Yes, some are harmful compounds. In the prior art, there may be the following defects: at least a part of the gas brew will condense in the conspicuous tube, and it will not only be sublimated at a later time. It causes high maintenance and purification costs, and poses a danger to the people who perform this work. Linli especially endangers certain "chemicals" whose meeting air thinness reverses the formation of hydrotalic acid, in the form of liquid brewing Exist in the pipeline system mentioned above . Only a few drops of hydrofluoric acid will cause heavy corrosion of the skin, and the fluorinated castor in the form of steam and gas will cause significant damage to the respiratory organs. Because it will produce better purification on the surface in the exhaust gas purification system. Effect, so some of the aforementioned condensate condensed in the pipeline, and some will be accepted. However, the cleanliness of the pipeline shows a great risk to the lumps, witnesses and equipment: because of Some of the suspicions have caused the convex »connection to form an unsealed shape, or even corrode through the pipeline. In addition, the exhaust gas reverse expansion (Rueckdiffusion) will be observed in the vacuum pump, where, for example, the drying pump process will be affected Dry j ».

V. Invention description (4) a is set on a common base frame and this pumping ae is placed on the separator Afterwards, because the general pressure can only be generated by pumping iaa, so the «known device is neither pre-Culu and is not suitable for use as a vacuum lotus. The pollution of the connecting pipe will not be separated due to separation The known arrangement order of Qiyu Fengfeng Temple is produced. The purpose of the present invention is to propose a type of β that has been described in Changyang, which has a vacuum system that clearly reduces the installation area, in the formation of «knots. It will stop with the results mentioned earlier, but at least it will be limited in the main quality μ. According to the present invention, the solution to this object can be achieved by the vacuum system described at the two ends: Yiyi vacuum pump The device has a europium, three-lobe, dry-type rotor pump, which is used for a kappa fan between 1 (Γ2 «bar and 1100 mbar. This type of three-blade dry rotor pump has the following characteristics and viscosity: 1. The release of coarse gas from the gas. 2. Low pressure fluctuations. According to the usage method of the present invention, the pumps are integrated into a component unit from the purification device to obtain a large disturbance. In addition to this, the lotus transfer method of the purification device in Kalu can be improved. , When it involves a furnace operated by flame. In addition, exhaust silencers can be eliminated. There is an additional benefit of 歭 榇: the exhaust gas path is not increased by the silencer and its internal surface area. As a result, the energy consumption is reduced, and the potentially dangerous cleaning position disappears, because the muffler is a kind of mailing material that is easy to condense.

At the end of the pipe, there is a cone «_ which is not further shown. S has a cut-off pipe 9b from the switching valve 22 to the exhaust pipe 12. In normal equipment operation , The cut-off pipe 9b is closed. Only in a short moment, when it is replaced or cleaned and burned "21 and / or the retort chamber 26, the exhaust gas can be directly introduced into the exhaust pipe 12. 2 shows: the whole vacuum The system can also be installed with seepage 3, which makes the moving position more convenient. However, in the pipeline reach adapter 8 and vacuum pump device 4 The module unit between the suction tank is equipped with a filter 31 and a closing valve 32. The latter has an advantage: it can also be used for the replacement and / or maintenance of the purification device when the vacuum pump device is turned on the surface, so that The start can be maintained at all times. Therefore, this equipment can be ready to rotate at full speed immediately to avoid the condensation of harmful substances in the vacuum pump device. The closing valve 32 is controlled by the controller 16 equipped with it, , There is no need for external control and wiring. The assembly is completely sealed, so there will not be too much pollution.. A central controller 16 is installed above the middle frame 14 and the controller 16 has An input keyboard 17 and a display device 18. The controller 16 controls the nickel pump 19 and the vacuum pump device 4 and / or the current M paper format through some data lines and uses the Chinese 8 standard (CNS) A4 specifications (210X297mm) •; f, ml- .ϋ ^ —-nn-^ 1 ^ 1 fl ^ i (please read the note $ item on the back and then fill in this page) Cooperation Du Yin «.315312 A7 B7 V. Description of invention (?) The controller is connected, and the two lines shown here represent all 19 lines. With the central controller 16 and 19, control commands such as Ma Fengliang, flush valve and cold water blue can be sent. Conversely, the adjustment signal The controller 15 will be notified via the line 19, and if necessary, the information will also be transmitted to the display device 18 for display. In addition, the central controller 16 is controlled by many data lines and control channels 20 and the purification device 10 Together, as in the above example, some of the roads are only represented by two suspected roads. In the Qi Huanfeng takeover 9, for example, the S force and Zhandu of the Qiju are passed to the control through the suspected 20 Fu器 16. 16. Similarly, the flame monitoring, temperature monitoring, water flow control, and the device of the Dong Dong holding device are also controlled by the same method. By discussing the important director of the waste pipe, we came to show the handling of the suction tube. The control yoke number is transmitted from the controller 16 to the purification device 10 in the opposite direction. Used for water washing, heat flow, and one that may exist in the tube. Thus, the volume data and the control signal of the beta device of the purification device 10 can be displayed in the indicator device 18. In addition, information such as adjustment commands and rated values can also be entered into the keyboard 16 keys to control the M 16. It can be known from _1 that the only controller can be used on the two devices by configuring the vacuum pump device 4 on the one hand and the purification device 10 on the other by the narrow space. The controller also does not require an additional placement position, but can be installed on the vacuum pump device 4. This results in a very compact vacuum system, which can be replaced by the replacement system in the shortest period of time. The whole material of the Shitou system and the purification device are in the view of the operator shell, which can avoid the control path between the two controllers. • If the aforementioned devices are placed in different places Installation is quite daunting -1 〇- This paper is again applicable to the Chinese National Elephant Standard (CNS) Α4 specifications (210 > < 297mm) ^^^ 1 · utt n ^ — I n ^ i I (please read the back first Note $ item and then fill this page)
