[0002] Coal gas fermentation to ethanol is a new technology that uses carbon monoxide as a carbon source to produce ethanol through bacterial bio-fermentation. After the fermentation wastewater is distilled to extract ethanol, a certain amount of bacterial protein is contained in the wastewater, which greatly increases the difficulty of sewage treatment. At the same time, the bacterial protein contained in the wastewater has a single component and a high crude protein content. It is a high-value-added protein feed that can be widely used in aquatic products, livestock and poultry feeding. Bacterial protein powder can replace part of fish meal in the feed industry to reduce the dependence of high-grade protein feed on marine fish, which has great environmental and economic significance.

DETAILED DESCRIPTION

[0029] In order to enable technicians in the technical field to which the present application belongs to understand the present application more clearly, the technical solution of the present application is described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0030] In the embodiments of the present application, as shown in the attached Figure 1 and attached Figure 2As shown, a cyclone separator includes a cyclone separator body 110 and a coarse slag processing device 120, the cyclone separator body 110 includes a cylindrical section 111, a conical section 112 and a discharge pipe 113 which are connected in sequence, the large diameter end of the conical section 112 is close to the cylindrical section 111, and the small diameter end of the conical section 112 is away from the cylindrical section 111 and is connected to the discharge pipe 113; the coarse slag processing device 120 is arranged at the conical section 112 and is connected to the conical section 112, the coarse slag processing device 120 includes a connecting pipe 121, a first valve 122 and a discharge unit 123, the connecting pipe 121 is connected to the conical section 112; the first valve 122 is arranged at the connecting pipe 121; the discharge unit 123 is connected to the connecting pipe 121, and the discharge unit 123 is used to collect coarse slag.

[0031] The cyclone separator 100 includes a cylindrical section 111, a conical section 112 and a discharge pipe 113 which are interconnected, wherein the cylindrical section 111, the conical section 112 and the discharge pipe 113 are sequentially connected along the axial direction, and an air inlet 115 and an air outlet 116 are provided at the top of the cylindrical section 111, wherein the air inlet 115 is connected to the drying tower 210, and the air outlet 116 is connected to the bag dust collector 220.

[0032] The coarse residue processing device 120 is used to collect the coarse residue in the cyclone separator 100, that is, to collect the larger coarse materials or foreign objects in the cyclone separator 100. In some embodiments, the cyclone separator 100 can be used in the protein drying system 200. In the protein drying system 200, the drying tower 210 in the protein drying system 200 separates the protein powder with larger particle size by centrifugal force at the air outlet; since the air outlet of the drying tower 210 enters tangentially from the air inlet 115 of the cyclone separator 100, and the lower part gradually narrows to the conical section 112, the cyclone separator 100 will rotate to produce external rotation and internal rotation, thereby causing some relatively large coarse materials or foreign objects to rotate in the cyclone separator 100. During the operation of the cyclone separator 100, some relatively large coarse materials or foreign objects have been rotating in the cyclone separator 100 due to "anticyclonic reasons". The coarse slag processing device 120 is disposed in the conical section 112 and is in communication with the conical section 112. The coarse slag processing device 120 includes a connecting pipe 121, a first valve 122, and a discharge unit 123. The connecting pipe 121 is in communication with the conical section 112; the first valve 122 is disposed in the connecting pipe 121; the discharge unit 123 is in communication with the connecting pipe 121, and the discharge unit 123 is used to collect coarse slag. By arranging the coarse slag processing device 120 in the conical section 112, when there is an abnormal sound in the cyclone separator 100, the first valve 122 can be opened, and the coarse slag or foreign matter can enter the discharge unit 123 through the connecting pipe 121 by centrifugal action, so as to timely collect the coarse slag or foreign matter rising with the "anticyclone".

[0033] Therefore, in the present application, a coarse slag treatment device 120 is provided in the conical section 112 of the cyclone separator body 110. By opening the first valve 122, the coarse slag or foreign matter rising due to the "anticyclone" can be timely collected into the discharge unit 123, reducing the rotation of coarse materials or foreign matter in the cyclone separator 100 all the time, reducing on-site noise pollution, and at the same time reducing the abrasion of the inner wall of the cyclone separator 100 by coarse materials or foreign matter, increasing the service life of the cyclone separator 100. In addition, it also prevents coarse materials or foreign matter from entering subsequent rotating equipment, reducing other mechanical damages and improving production efficiency.

[0034] To facilitate the installation of the coarse slag treatment device 120 on the cyclone separator 100, in some embodiments, as shown in the appendix Figure 1 An installation hole 114 for connecting the connecting pipe 121 is provided in the conical section 112, that is, an installation hole 114 is provided in the conical section 112 of the cyclone separator 100, and the connecting pipe 121 is installed at the installation hole 114 of the cyclone separator 100. In certain embodiments, the connection hole and the cyclone separator 100 can be connected by seamless welding to ensure the sealing performance of the connection between the cyclone separator 100 and the coarse slag treatment device 120. In certain embodiments, the size of the installation hole 114 needs to be larger than the size of foreign matter or coarse slag to facilitate the entry of coarse slag or foreign matter into the discharge unit 123 from the installation hole 114.

[0035] In some embodiments, as shown in the appendix Figure 1 The connecting pipe 121 is arranged at an angle with the axis of the conical section 112, and the installation hole 114 is opened on the side wall of the conical section 112. To facilitate the connection between the connecting pipe 121 and the conical section 112, the connecting pipe 121 is perpendicular to the axis of the conical section 112. After the connecting pipe 121 is connected to the conical section 112, the smoothness and sealing performance of the gas are ensured.

[0036] In other embodiments, as shown in the appendix Figure 1 The installation hole 114 is located above the blanking pipe. The position of the "anticyclone" is generally near the connection between the conical section 112 and the blanking pipe. Therefore, by arranging the installation hole 114 above the position of the anticyclone, the coarse slag or foreign matter rising with the "anticyclone" can be timely collected.

[0037] To facilitate the discharge unit 123 to process the coarse slag or foreign matter, in some embodiments, as shown in the appendix Figure 1As shown, the discharge unit 123 includes a collection bin 1231 and a discharge pipe 1232 communicating with the collection bin 1231. The collection bin 1231 is provided with a collection cavity, and the discharge pipe 1232 is provided with a second valve 1233. By opening the first valve 122, the coarse slag or foreign matter rising in the "anticyclone" rises in the conical section 112 and is collected into the discharge unit 123 through the connecting pipe 121, that is, the coarse slag or foreign matter can enter the collection bin 1231. When it is necessary to discharge the coarse slag or foreign matter collected in the collection bin 1231, the second valve 1233 can be opened, and the coarse slag or foreign matter can be discharged through the discharge pipe 1232. In some embodiments, in order to facilitate the treatment of the coarse slag or foreign matter, a collection bag (not shown in the figure) can be sleeved in the discharge pipe 1232, and then collected through the collection bag.

[0038] In some embodiments, as shown in the appendix Figure 1 As shown, in order to facilitate the discharge of the coarse slag or foreign matter through the discharge pipe 1232, the discharge pipe 1232 is arranged at an angle with the axis of the collection bin 1231. In some embodiments, the discharge pipe 1232 is perpendicular to the axis of the collection bin 1231.

[0039] In order to facilitate the collection of the coarse slag or foreign matter in the collection bin 1231 through the discharge pipe 1232, in some embodiments, as shown in the appendix Figure 1 As shown, the collection bin 1231 has a first end and a second end arranged oppositely, and the inner diameters of the first end and the second end show a gradually increasing trend. The inner diameter of the collection bin 1231 can increase linearly, non-linearly or in a gradient manner from the first end to the second section. The increasing trend of the collection bin 1231 from the first end to the second section can facilitate the entry of the coarse slag or foreign matter into the collection bin 1231 under the action of the centrifugal force in the cyclone separator 100.

[0040] In some embodiments, as shown in the appendix Figure 1 As shown, the discharge pipe 1232 is arranged at the second end of the collection bin 1231, and the coarse slag or foreign matter can slide from the first end to the second end along the inner wall of the collection bin 1231, facilitating falling into the discharge pipe 1232.

[0041] In some embodiments, as shown in the appendix Figure 1 As shown, the collection bin 1231 is conical, facilitating the sliding of the coarse slag or foreign matter from the first end to the second end along the inner wall of the collection bin 1231 and falling into the discharge pipe 1232. In some embodiments, the first end of the collection bin 1231 is communicated with the connecting pipe 121, and a portal manhole 1234 is provided at the second end of the collection bin 1231, that is, the axis of the collection bin 1231 is horizontally arranged. In addition, a portal manhole 1234 is provided at the second end of the collection bin 1231, which facilitates the entry of the staff or inspection of the interior of the container when the collection bin 1231 is blocked or the like, facilitating maintenance and cleaning.

[0042] In addition, in order to further facilitate the staff to enter or inspect the interior of the container, in some embodiments, the side of the collection bin 1231 close to the portal manhole 1234 is cylindrical.

[0043] In some embodiments, as shown in the appendix Figure 1 The first valve 122 is a blind plate valve. The blind plate valve can be an 8-shaped blind plate valve. The 8-shaped blind plate valve can completely cut off the fluid when closed, and can provide an unobstructed channel when opened. The second valve 1233 is a butterfly valve.

[0044] In some embodiments, as shown in the appendix Figure 1 The cyclone separator 100 further includes a controller and more than one noise detector 130. The noise detector 130 is arranged in the conical section 112, that is, the noise detector 130 arranged in the conical section 112 can timely detect whether there is coarse slag or foreign matter in the cyclone separator 100. In some embodiments, there can be 3 noise detectors 130, and the 3 noise detectors 130 are all arranged in the conical section 112. Among them, the 3 noise detectors 130 can be located on the same horizontal plane of the conical section 112, or on different horizontal planes. In other embodiments, the 3 noise detectors 130 are located on the same horizontal plane of the conical section 112, and the 3 sets of noise detectors 130 are evenly distributed on the same horizontal plane, which can more comprehensively detect whether there is coarse slag or foreign matter in the cyclone separator 100. In addition, in order to avoid misoperation, at least 2 of the 3 noise detectors 130 need to detect the noise of the coarse slag or foreign matter touching the wall before the coarse slag treatment device 120 is started.

[0045] For the convenience of the controller operation, in some embodiments, as shown in the appendix Figure 1 The first valve 122 and the second valve 1233 are both electric valves. The controller is electrically connected to the noise detector 130, the first valve 122 and the second valve 1233. That is, when the noise detector 130 detects coarse slag or foreign matter, the first valve 122 can be controlled by the controller to open, and the second valve 1233 to close. After the coarse slag or foreign matter is collected, the first valve 122 is closed and the second valve 1233 is opened.

[0046] In some embodiments, as shown in the appendix Figure 1 The noise detector 130 is located above the connection between the connecting pipe 121 and the conical section 112. It can timely detect the coarse slag or foreign matter in the cyclone separator 100, and the collection work of the coarse slag or foreign matter can be carried out.

[0047] Thus, the noise detector 130 can timely detect whether there is coarse slag or foreign matter inside the cyclone separator 100. When the noise detector 130 reaches the set decibel value, the collection work of the coarse slag or foreign matter can be carried out.

[0048] In some embodiments, in order to improve the durability of the coarse slag processing device 120, the connecting pipe 121, the collecting pipe and the collecting bin 1231 are all made of stainless steel.

[0049] In the second aspect of this application, as attached Figure 2 As shown, a protein drying system 200 is provided, comprising the above-mentioned cyclone separator 100. The protein drying system 200 has all the features of the cyclone separator 100 in the above-mentioned embodiment, which will not be described in detail here.

[0050] In some embodiments, as shown in the attached Figure 2 As shown, the protein drying system 200 also includes a drying tower 210, a bag dust collector 220, a Du Kang cone 230 and an air duct 240. The drying tower 210 is connected to the air inlet of the cyclone separator 100; the bag dust collector 220 is connected to the air outlet of the cyclone separator 100; the Du Kang cone 230 is connected to the discharge pipe 113 of the cyclone separator 100, and a rotary unloading valve 231 is provided on the Du Kang cone 230; and the air duct 240 is connected to the Du Kang cone 230.

[0051] When the protein powder-containing gas enters the air inlet 115 of the cyclone separator 100 tangentially from the air outlet of the drying tower 210 through pipeline transportation, the airflow is guided in the column and runs in a spiral shape. The larger protein powder, coarse slag and foreign matter lose inertia after touching the barrel wall. The protein powder falls along the barrel wall under the action of gravity, enters the lower end Du Kang cone 230 for collection, and is unloaded to the air delivery pipe 240 through the rotary discharge valve 231, and is pneumatically transported to the packaging system for packaging. Coarse slag and foreign matter can be collected by the coarse slag processing device 120, and the remaining gas containing smaller particle protein powder will generate an anticyclone after the cone section touches the bottom. After the gas runs to the upper end of the cyclone separator 100 through the anticyclone, it comes out from the upper end air guide cylinder and is transported to the bag filter 220 through the pipeline to capture smaller particle protein powder again.

[0052] Through the above embodiments, the present application has the following beneficial effects or advantages:

[0053] 1) The present application provides a coarse slag processing device at the lower end of the cyclone separator, which can timely process and collect the coarse slag or foreign matter, reduce the wear of the coarse slag or foreign matter on the inner wall of the cyclone separator, reduce noise pollution, and increase the service life of the equipment.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0055] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the spirit and scope of this application.
