Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, the use of the terms of orientation such as "inside and outside" means inside and outside with respect to the outline of each member itself, unless otherwise specified; this is done solely for the purpose of facilitating the description of the invention and simplifying the description without indicating that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation and therefore should not be construed as limiting the invention. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The invention provides a fluid filling device, as shown in figure 1: the fluid filler comprises a first pipeline 1 and a second pipeline 2; wherein, the first end of the first pipeline 1 is used for connecting a first fluid source, and the second end of the first pipeline 1 leads to the next process; the first end of the second pipe 2 is used for connecting a second fluid source, the second end of the second pipe 2 extends into the first pipe 1, and the end surface of the second end of the second pipe 2 is close to the center line of the first pipe 1, so that the second fluid flowing into the first pipe 1 from the second pipe 2 and the first fluid in the first pipe 1 form turbulent flow. By means of the fluid filler, the tail end of the second pipeline 2 is inserted into the position close to the center line of the first pipeline 1, the second fluid is enabled to form turbulence with the first fluid after being injected into the first fluid, the first fluid and the second fluid can be mixed uniformly and rapidly, and corrosion to a pipeline comprising the first pipeline 1 is effectively prevented.
Preferably, the first pipe 1 comprises a first shell 11 and a first protective layer 12 covering the inner wall of the first shell 11. The first housing 11 can be protected from corrosion by the first fluid or by a mixed fluid formed by the first fluid and the second fluid by providing the first protective layer 12.
Preferably, the first protective layer 12 is a polytetrafluoroethylene layer. The use temperature can be suitable for the temperature environment of-250-260 ℃, and the corrosion resistance is strong and the chemical stability is good.
Preferably, the second pipe 2 includes a second casing 21 and a second protective layer 22 covering an inner wall of the second casing 21. The second casing 21 can be protected from the mixed fluid formed by the first fluid and the second fluid or from the second fluid by providing the second protective layer 22.
Preferably, the second protective layer 22 is a polytetrafluoroethylene layer. The advantages of using a polytetrafluoroethylene layer are as described above.
Preferably, the first pipeline 1 is formed by splicing a plurality of pipeline segments, wherein the first pipeline 1 and the second pipeline 2 are connected to a first connecting segment 13 located at the middle part of the plurality of pipeline segments. With the operation of the equipment, since the joint of the first pipeline 1 and the second pipeline 2 is easy to be damaged, if all the first protective layer 12 in the first pipeline 1 is replaced, the cost is high; through the segmentation setting, set up the second protective layer 22 at the position that the easy emergence of first pipeline 1 damaged and the first casing 11 part that this position corresponds into the first linkage segment 13 that can dismantle, like this, generally only need change first linkage segment 13 inside second protective layer 22 can, and needn't change whole second protective layer 22 in the first pipeline 1, very big saving the cost, moreover, the change work is simpler, easy to operate.
Preferably, the second pipe 2 is perpendicular to the first pipe 1, and both ends of the first connecting section 13 are equidistant from a center line of the second pipe 2. With this arrangement, since the second pipe 2 is perpendicular to the first pipe 1, and the second fluid flowing from the second pipe 2 into the first pipe 1 is similarly uniformly diffused in the first fluid in the first pipe 1, the abrasion of the second protective layer 22 is substantially symmetrically distributed centering on the center line of the second pipe 2, and therefore, the distances from both ends of the first connecting section 13 to the center line of the second pipe 2 are set to be equal. This makes it easier to handle when replacing the first connecting section 13 and also to machine the first connecting section 13.
Preferably, the second pipe 2 is formed by splicing a plurality of pipes, and the second pipe 2 comprises a second connecting section 23 extending from the outside of the first pipe 1 into the inside of the first pipe 1. This arrangement is mainly to prevent that at the moment when the first fluid source stops supplying the second fluid to the second pipe 2, the second fluid pressure in the second pipe 2 becomes lower, which may cause the first fluid to flow backward along the second pipe 2 under the pressure of the first fluid source, i.e. to move from the second end of the second pipe 2 to the first end of the second pipe 2, which may cause the second end of the second pipe 2 to be easily worn. Because, in order to reduce the maintenance cost, the second pipe 2 is configured to be composed of a multi-segment pipe splice in which the second connection segment 23 and the first connection segment 13 are connected, the length of the second connection segment 23 is determined according to the pressure of the first fluid source and the inner diameter size of the first pipe 1.
Preferably, the first pipe 1 includes a through hole 111 formed on a pipe wall of the first pipe 1 for passing the second pipe 2 therethrough; the outer surface of the second pipe 2 and the inner wall of the through hole 111 are connected without a gap. By the arrangement, the fluid can be prevented from flowing out from the joint of the first pipeline 1 and the second pipeline 2, and pollution and damage to the outside can be prevented.
In a second aspect the present invention provides a fluid injection method for mixing sulphuric acid and mash, the method employing injecting a second fluid into a linearly flowing first fluid such that the second fluid creates turbulence within the first fluid, wherein the first fluid is mash and the second fluid is sulphuric acid. This enables the first fluid and the second fluid to be mixed uniformly and rapidly.
Preferably, the second fluid may be added to the first fluid in a direction perpendicular to the flow direction of the first fluid. Therefore, on one hand, the first fluid and the second fluid can be mixed uniformly as fast as possible, and on the other hand, the first fluid can be prevented from flowing back to the second fluid. If there is an included angle between the first fluid and the second fluid, it is not favorable for turbulence when the flow direction between the first fluid and the second fluid is acute; when the flow direction between the first fluid and the second fluid is obtuse, although it is easier to form turbulence, the first fluid may flow back into the second fluid, thereby affecting the final result. The direction of the second fluid perpendicular to the flowing direction of the first fluid is added into the first fluid, so that the first fluid and the second fluid are mixed uniformly as fast as possible, and the first fluid can be prevented from flowing back to the second fluid.
Preferably, the second fluid is injected into the first fluid using an injector comprising a valve according to the above. The technical advantages of this method of filling fluid are similar to those of the above-described fluid filler and will not be described in detail herein.
To further illustrate the invention, a fluid addition method for adding sulfuric acid to mash is further described, in which method the first fluid in the first conduit 1 is provided as mash and the first fluid in the second conduit 2 is provided as sulfuric acid. The second pipeline 2 is set into a two-section structure: a second connecting section 23 and a third flow-through section 24. Wherein, the second connecting section 23 and the third flow-through section 24 are connected through the first connecting unit 3; the first connection unit 3 may be provided as a loose-flange connection for ease of connection. The second pipe 2 is manufactured by inserting the end surface of the second connecting section 23 facing the end of the first pipe 1 into the vicinity of the center line of the first pipe 1 and welding the outer wall of the second connecting section 23 and the inner wall of the through-hole 111. The first pipeline 1 is provided with a three-section structure: a first connecting section 13, a first flow-through section 14 and a second flow-through section 15, the first connecting section 13 being arranged between the first flow-through section 14 and the second flow-through section 15. The second flow-through section 15 is connected with the first connecting section 13 by the third connecting unit 5, and the first flow-through section 14 is connected with the first connecting section 13 by the second connecting unit 4. Wherein, the second connecting unit 4 and/or the third connecting unit 5 also adopt ring loose flanges. The first end of the first conduit 1 opens into a first fluid source providing mash, which mash flows from the second flow-through section 15 into the first conduit 1 and then out of the first conduit 1 from the first flow-through section 14 and into the next process step; the first end of the second pipe 2 leads to a second fluid source providing sulfuric acid; the sulfuric acid flows through the third flow section 24 into the second conduit 2 and is then injected into the mash in the first conduit 1 through the second connecting section 23 and forms a turbulent flow. In order to create turbulence, in addition to bringing the end surface of the second end of the second pipe 2, i.e. the end surface of the end of the second connecting section 23 facing away from said third flow-through section 24, close to the vicinity of the centre line of the first pipe 1, it is necessary to give the sulfuric acid and mash a certain velocity and pressure so that the sulfuric acid and mash form turbulence to achieve a fast and uniform mixing of sulfuric acid and mash. The rapid and uniform mixing of the sulfuric acid and the mash can reduce the corrosion to a pipeline comprising the first pipeline 1 on the one hand, and can effectively inhibit the growth of mixed bacteria and simultaneously reduce the damage to beneficial bacteria as much as possible and improve the production quality of alcohol on the other hand.

Including each of the specific features, are combined in any suitable manner. The invention is not described in detail in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
