Description

Technical Field

[0001] The utility model relates to a distillation tower, in particular to an anti-clogging ethanol distillation tower. Background Art

[0002] After production, the company discharges low-concentration ethanol, which contains protein wastewater. The low-concentration ethanol needs to be distilled, which requires the use of an ethanol distillation tower.

[0003] In the prior art, an ethanol distillation tower includes a tower body, inclined hole plates, and valve plates. A distillation chamber is formed at the bottom of the tower body, which is used to store low-concentration ethanol to be distilled. A feed port is provided in the middle of the tower body, and several layers of valve plates and inclined hole plates are installed in the tower body. The several layers of valve plates are all arranged below the feed port, and inclined hole plates are all arranged above the feed port. The low-concentration ethanol to be distilled is heated in the distillation chamber, and the ethanol evaporates, while water vapor also moves upward from the distillation chamber.

[0004] Although the ethanol distillation tower can distill ethanol, the ethanol distillation tower still has the following problems: Figure 1 As well as the inclined hole plate shown in 2, the inclined hole plate is provided with a plurality of inclined holes, the inclined holes being smaller; Figure 3 As shown, the floating valve plate includes: a plate body and a floating valve, the plate body is provided with an air vent, the diameter of the air vent is larger than the diameter of the inclined hole, and a floating valve that can float up and down is installed in the air vent; since the low-concentration ethanol discharged by the company contains a large amount of protein, although the floating valve in the floating valve plate below the feed port makes the steam tend to move horizontally, so that the protein can fully contact the floating valve plate, and then the protein can be blocked and attached to the floating valve plate, but since there is still protein entering from above the feed port, the inclined hole plate is blocked, which in turn causes the entire ethanol distillation tower to malfunction, and after the inclined hole plate is blocked, it is difficult to clean out the protein because the inclined hole is inclined and small. Utility Model Content

[0005] The utility model provides an anti-clogging ethanol distillation tower, which solves the problem in the prior art that the inclined perforated plates above the feed inlet are easily clogged because the inclined perforated plates above the feed inlet are all arranged thereon.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The utility model discloses an anti-clogging ethanol distillation tower, comprising: a tower body and a filter assembly, a distillation chamber is formed at the bottom of the tower body, a filter assembly is installed in the tower body and is located above the distillation chamber, and a feed inlet is provided in the middle of the tower body; the filter assembly comprises: a lower filter plate group and an upper filter plate group, the lower filter plate group is located between the feed inlet and the distillation chamber, and the upper filter plate group is located above the feed inlet; the lower filter plate group comprises a plurality of floating valve plates arranged up and down; the upper filter plate group comprises: a protein blocking group and a filter blocking group, the protein blocking group is located below the filter blocking group and is located next to the feed inlet, and the protein blocking group comprises at least two floating valve plates arranged up and down.

[0008] Preferably, the filter blocking group includes a plurality of inclined hole plates arranged up and down, and the inclined hole plates are provided with inclined holes.

[0009] Preferably, the protein barrier group comprises three valve trays.

[0010] Preferably, the floating valve trays are all detachably connected to the tower body.

[0011] Preferably, the floating valve tray comprises a plate body and a floating valve. The plate body is detachably connected to the tower body. A plurality of vents are provided on the plate body. The floating valves are installed in the vents. The floating valves can float relative to the plate body buoy.

[0012] Preferably, the floating valve includes: a valve top cover, an anti-slip foot and an extrusion push ring. The valve top cover is equipped with an anti-slip foot. The connection between the anti-slip foot and the valve top cover is elastic. An anti-slip hook is formed at the bottom end of the anti-slip foot. A plate is installed between the anti-slip hook and the valve top cover. The anti-slip hook is used to limit the detachment of the floating valve from the plate. There are at least two anti-slip feet. All anti-slip feet are surrounded by an extrusion push ring. The extrusion push ring is located between the anti-slip hook and the valve top cover. The extrusion push ring is used to bring all anti-slip hooks close to each other.

[0013] Preferably, the extrusion push ring includes: a ring body and a convex ring, the ring body is a hollow cylindrical structure, the inner wall of the ring body protrudes to form a convex ring, and the convex ring is used to squeeze all the anti-detachment hooks close to each other.

[0014] Preferably, a guide block is provided on the valve top cover, and the ring body and the guide block are positioned by screws.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present application, first, all the filter assemblies composed of valve plates and inclined hole plates are classified relative to the feed port. In order to avoid protein in low-concentration ethanol clogging the lower filter plate group below the feed port, the lower filter plate group is entirely composed of valve plates arranged up and down; then, since the treatment target of the present application is low-concentration ethanol with a higher protein concentration, it is very likely that protein will clog the upper filter plate group, so more than two valve plates are set near the feed port in the upper filter plate group, and more than two valve plates near the feed port in the upper filter plate group replace the inclined hole plates in the prior art. Since the possibility of protein entering above the feed port is small, at least two valve plates are designed above the feed port, and the optimal number is three valve plates above the feed port, thereby reducing the possibility of protein entering the inclined hole plate at the top of the tower body, and the possibility is almost 0, thereby reducing the possibility of the entire tower body being blocked, so that the tower body can be used normally for a long time. After a certain period of time, only the valve plates need to be cleaned because the upper inclined hole plates have no possibility of blockage.

[0017] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below with reference to the accompanying drawings and specific embodiments:

[0027] like Figure 4 As shown, the utility model discloses an anti-clogging ethanol distillation tower, comprising: a tower body 3 and a filter assembly, a distillation chamber is formed at the bottom of the tower body 3, a filter assembly is installed in the tower body 3 and is located above the distillation chamber, and a feed port 30 is provided in the middle of the tower body 3; the filter assembly comprises: a lower filter plate group 41 and an upper filter plate group 42, the lower filter plate group 41 is located between the feed port 30 and the distillation chamber, and the upper filter plate group 42 is located above the feed port 30; the lower filter plate group 41 includes a plurality of floating valve tower plates arranged up and down; the upper filter plate group 42 includes: a protein blocking group and a filter blocking group, the protein blocking group is located below the filter blocking group, and the protein blocking group is located next to the feed port 30, and the protein blocking group includes at least two floating valve tower plates arranged up and down.

[0028] The filter barrier group includes a plurality of inclined hole plates 1 arranged up and down, and the inclined hole plates 1 are provided with inclined holes 10. The design of the inclined hole plates 1 is

[0029] The protein barrier group includes three valve trays.

[0030] The valve trays are all detachably connected to the tower body 3 to facilitate cleaning of the valve trays.

[0031] like Figures 5 to 7 As shown, the floating valve tower plate includes: a plate body 21 and a floating valve 22. The plate body 21 is detachably connected to the tower body 3. A plurality of vents are opened on the plate body 21. The floating valve 22 is installed in the vents. The floating valve 22 can float relative to the buoy of the plate body 21.

[0032] The float valve 22 includes a valve top cover 221, an anti-slip foot 222, and a squeeze-pushing ring 223. The valve top cover 221 is mounted with an anti-slip foot 222. The connection between the anti-slip foot 222 and the valve top cover 221 is elastic. An anti-slip hook is formed at the bottom of the anti-slip foot 222. A plate 21 is mounted between the anti-slip hook and the valve top cover 221. The anti-slip hook is used to prevent the float valve 22 from separating from the plate 21. There are at least two anti-slip feet. Each anti-slip foot is surrounded by an squeeze-pushing ring 223. The squeeze-pushing ring 223 is located between the anti-slip hook and the valve top cover 221. The squeeze-pushing ring 223 is used to bring all the anti-slip hooks 228 closer together, allowing the plate 21 to float between the valve top cover 221 and the anti-slip hook. Under the elastic force of the anti-slip foot 222, the anti-slip hook 228 is in an open state, at which point the anti-slip hook cannot pass through the vent hole in the plate 21. Through the design of the extrusion push ring 223, it is possible to push one extrusion push ring 223 to make all the anti-detachment hooks move closer to each other, so that all the anti-detachment hooks pass through the vent hole at one time, so that the entire floating valve 22 is separated from the vent, making it convenient to remove the floating valve 22 and clean the plate body 21.

[0033] The anti-slip hook 228 is an anti-slip foot that protrudes radially from the valve top cover 221. The anti-slip hook 228 extends in a direction away from the axial centerline of the valve top cover 221. A notch 31 is provided on the valve top cover 221, and the notch 31 is aligned with the anti-slip hook. This allows the anti-slip hook, the anti-slip foot, and the valve top cover 221 to be formed in a single upper and lower mold. The notch design ensures that the anti-slip foot with the anti-slip hook is already formed after being pulled out of the mold, facilitating demoulding. This also eliminates the need for subsequent bending to form a bend between the anti-slip foot and the valve top cover 221. The thinner connection between the anti-slip foot and the valve top cover 221 allows for elasticity at the connection, ensuring both strength at the anti-slip foot and the valve top cover 221 and the formation of the anti-slip hook in a single mold.

[0034] The surface of the anti-slip foot away from the axial center line of the valve top cover 221 is an extrusion surface, which is used for extrusion with the extrusion push ring 223.

[0035] The extrusion and pushing ring 223 includes: a ring body 224 and a convex ring 225. The ring body 224 is a hollow cylindrical structure. The inner wall of the ring body 224 protrudes to form a convex ring 225. The convex ring 225 is used to squeeze all the anti-detachment hooks closer to each other. The convex ring 225 squeezes all the anti-detachment hooks closer to each other.

[0036] A guide block 226 is provided on the valve top cover 221 , and the ring body 224 and the guide block 226 are positioned by screws 227 . The guide block 226 guides the ring body 224 to move between the anti-off hook and the valve top cover 221 .

[0037] The ring body 224 is provided with ventilation holes to prevent the installation of the ring body 224 from affecting the exhaust.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
