本発明は蒸気エゼクタ−のデフユーザー構造を変えで、

特殊エゼクタ−である。[Detailed description of the invention] The present invention changes the differential user structure of the steam ejector,
By installing a Panful block with a step change in shape similar to a circle (quasi-shaped or polygonal pyramid, etc.) inside, the reduced area effect of the double pipe is created, and the Panful block The purpose is to convert the passing fluid with high velocity energy into effective pressure energy by applying a large flow resistance to the fluid.
It is a special ejector.

ルギーへの効率の高い変換を可能にする事が出来た。The high-speed steam flow blown into the differential user sucks bleed gas from the suction chamber and travels straight through the differential user, but the cone-shaped baffle block installed later creates a double cylinder that gradually shrinks. Due to the resistance phenomenon to the passing fluid caused by the flow path and conical shape, the fluid passes through while being pressed against the inner wall of the differential user on the outer periphery. By simultaneously applying the shock of wall pressure immediately after the steam starts running at high speed, we were able to achieve a rapid and highly efficient conversion of velocity energy into pressure energy.

換を可能にし、大きな成果を挙げる事が出来た。The conventional ejector has four tapered ends as shown in Figure 1.
') Tefyuuser, 5. Def user throat, 6
The result is a combination of three differential users, a differential user that spreads out at the end, and its total length is about 21@ of the inner diameter of the differential user throat, and the steam flow ejected from the nozzle uses a relatively long distance to reduce the pressure. However, the aim of this ejector is to compress oil and air in the shortest distance possible, and as a result of various experiments and trials, the length of the conventional ejector is approximately 1/2 of the length of the differential user. By using a differential user with a dimensional ratio of 115, which is a combination of a straight pipe-based differential user and one conical baffle block, it is possible to effectively convert velocity energy into pressure energy, achieving great results. I was able to do something.

ての対応としては、一度設定された条件下で稼動する事
で、此の面から来る、余佑取り過ぎの弊害も出で、エネ
ルギーの労費に連がる可能性も大きい。The ejector must maintain stable performance over a long period of time, and must satisfy the most severe load conditions considered at the time of planning and design. As a response to the actual operation, once the system is operated under the set conditions, the negative effects of using too much surplus space will arise from this aspect, which will lead to higher labor costs for energy. There's a big possibility.

の重要な変動要因である。In addition to these variable load conditions, the conditions for this ejector vary greatly depending on the region, but the temperature of the condensing water that occurs due to seasonal changes is also large, ranging from 3 to 4 degrees Celsius to 32 degrees Celsius.
~33 degrees C1 In Southeast Asia, it is 36 degrees ~4
The change in radiation pressure caused by the temperature difference from 0 degrees Celsius and the influence on suction pressure are important fluctuation factors for extremely large energy savings.

However, this ejector could be designed by incorporating variable elements into the equipment elements as follows.

られる。-1- Adjustment of expansion ratio Nozzle expansion ratio adjustment requires selection of a more effective expansion ratio due to fluctuations in suction conditions. Leaks, raw material differences,
In addition to fluctuations in steam or paper generation due to differences in operating conditions, there are disturbance factors due to changes in cooling water temperature due to seasonal fluctuations. There are many possible variations in conditions on the suction side.

事を可能にした。Due to these factors, in addition to adjusting the reduction area ratio within the differential user described in the next section, the relative position between the nozzle 3 in the diagrams shown in Figures 2 and 6 and the tip of the baffle block 9 will be changed. This makes it possible to adjust the nozzle expansion ratio.

が極めて大きい。-2- Adjustment of Compression Ratio The factors that cause the compression ratio to vary are the load fluctuations described in the previous section, and the influence on the operation of the condensing cooling water, which has large seasonal fluctuations, is extremely large.
此の冷却水温度の大巾な変動は結果として圧縮比に大き
な影響を与え、実際の高い真空を得る場合大きく実仕事
量が変って来る。As a result, this wide fluctuation in cooling water temperature has a large effect on the compression ratio, and the actual amount of work required to obtain an actual high vacuum changes greatly.

出来た。This ejector is a method of adjusting the device to accommodate fluctuations in compression ratio by changing the differential user reduction area ratio. This was achieved by adjusting the double flow path with the outer peripheral surface of the block, that is, by changing the longitudinal position of the backful block inside the differential user.

By adjusting this, we were able to create a facility that could adjust the area ratio in response to changes in the compression ratio.

Seasonal changes in condensate temperature have a very large effect on the compression ratio.

orr = 6.3 Naturally, the amount of work is small in the winter, and if this compression ratio is commensurate with the amount of steam required, the amount of steam used in the winter should be around 30%. Since the ejector has a fixed area ratio and expansion ratio,
There is almost no difference in the amount of steam during the winter season.
