Description

Technical Field

[0001] This invention relates to a hydrolysis system, and more particularly to a high-temperature atomizing hydrolysis system equipped with a pressure relief device. Background Technology

[0002] An existing hydrolysis system (as shown in Chinese Utility Model Patent Publication No.: CN 2309715Y) includes a furnace body, a pot body composed of an inner cylinder and an outer cylinder, a safety valve communicating with the inner cylinder, and an exhaust valve communicating with the inner cylinder. In actual operation, feathers and an appropriate amount of water are added to the inner cylinder of the pot body, and the pot body is placed on the furnace body. The heat transfer medium in the multiple heating pipes on the furnace body is introduced into the interlayer cavity defined between the inner cylinder and the outer cylinder to perform hydrolysis on the feathers in the inner cylinder.

[0003] However, when performing depressurization operations, the exhaust valve needs to be opened to release water vapor. At this time, byproducts (such as particulates) generated during the hydrolysis operation are quite likely to be ejected along with the water vapor, causing pollution. Summary of the Invention

[0004] The purpose of this invention is to provide a high-temperature atomization hydrolysis system with a pressure relief device that can overcome the above-mentioned disadvantages.

[0005] This invention discloses a high-temperature atomized hydrolysis system with a pressure relief device, comprising a hydrolysis furnace and a pressure relief device. The hydrolysis furnace defines a reaction space and an exhaust port communicating with the reaction space. The pressure relief device includes a pressure relief pipe extending vertically and communicating with the exhaust port, and at least one auxiliary pipe disposed on the side of the pressure relief pipe away from the hydrolysis furnace, the auxiliary pipe extending radially along the pressure relief pipe and communicating with the exhaust port.

[0006] The high-temperature atomizing hydrolysis system with a pressure relief device according to the present invention has a pressure relief pipe having a small-diameter pipe section disposed on the top side of the hydrolysis furnace, a gradually expanding pipe section connected to the top end of the small-diameter pipe section, and a large-diameter pipe section connected to the top end of the gradually expanding pipe section. The gradually expanding pipe section gradually expands from the side approaching the small-diameter pipe section to the side approaching the large-diameter pipe section, and communicates between the small-diameter pipe section and the large-diameter pipe section.

[0007] The high-temperature atomization hydrolysis system with a pressure relief device according to the present invention includes two auxiliary pipes disposed on the side of the pressure relief pipe away from the hydrolysis furnace, and the auxiliary pipes together surround an axis that is substantially perpendicular to the vertical direction.

[0008] The high-temperature atomizing hydrolysis system with a pressure relief device of the present invention includes a hydrolysis furnace comprising a shell defining the reaction space and the exhaust port, and a stirring module disposed within the shell and located in the reaction space.

[0009] The high-temperature atomizing hydrolysis system with a pressure relief device of the present invention has an outer shell body and two support members disposed on the bottom side of the outer shell body. The length of the tube defined by the pressure relief device extending in the vertical direction is not less than the height of the furnace body defined by the outer shell body extending in the vertical direction.

[0010] The high-temperature atomization hydrolysis system with a pressure relief device of the present invention has a stirring module comprising a stirring support fixed inside the outer shell and located in the reaction space, a support rod rotatably disposed on the stirring support, and a plurality of stirring rods fixedly disposed at intervals along the left-right direction on the support rod.

[0011] The high-temperature atomization hydrolysis system with a pressure relief device of the present invention has a rod body and two plates respectively connected to the two ends of the rod body. The rod body defines a mounting hole for the support rod to be fixedly inserted.

[0012] The beneficial effect of the present invention is that by setting the pressure relief device to provide an appropriate buffer distance during pressure relief operations, a large amount of by-products generated during hydrolysis operations are prevented from overflowing into the air pollution treatment device, thereby reducing the load on the air pollution treatment device.

[0019] See Figure 1 and Figure 2 An embodiment of the high-temperature atomization hydrolysis system of the present invention, which includes a pressure relief device, is suitable for use in conjunction with a temperature control device (not shown), a pressure control device (not shown), and an air pollution treatment device (not shown) to perform hydrolysis operations.

[0020] The embodiment includes a hydrolysis furnace 1 and a pressure relief device 2 disposed on the hydrolysis furnace 1 along a vertical direction D1.

[0021] The hydrolysis furnace 1 defines a reaction space 10 for containing materials, an inlet 11 connected to the reaction space 10 for feeding materials, an inlet valve (not shown) located at the inlet 11, an outlet 12 connected to the reaction space 10 for discharging materials, an outlet valve (not shown) located at the outlet 12, a maintenance port 13 connected to the reaction space 10 for access by maintenance personnel, a maintenance cover (not shown) covering the maintenance port 13, two steam holes 14 connected to the reaction space 10 for allowing high-temperature atomized water vapor to pass through, and an exhaust port 15 connected to the reaction space 10. In this embodiment, both the inlet valve and the outlet valve are ball valves, and the maintenance cover is a flange blind plate.

[0022] The hydrolysis furnace 1 includes a shell 16 defining the reaction space 10, the feed inlet 11, the discharge outlet 12, the maintenance port 13, and the exhaust port 15, and a stirring module 17 disposed within the shell 16 and located in the reaction space 10. In this embodiment, the capacity of the hydrolysis furnace 1 is between 5 and 15 cubic meters. The material consists of at least one of poultry and livestock feathers and poultry and livestock by-products (e.g., head, claws).

[0023] The outer casing 16 has an outer casing body 161 and two support members 162 disposed on the bottom side of the outer casing body 161.

[0024] The stirring module 17 has a stirring support 171 fixed inside the outer shell 16 and located in the reaction space 10, a support rod 172 rotatably disposed on the stirring support 171, and a plurality of stirring rods 173 fixed at intervals along a left-right direction D2 on the support rod 172.

[0025] Each stirring rod 173 has a rod body 174 and two plates 175 respectively connected to both ends of the rod body 174. The rod body 174 defines a mounting hole 176 for the support rod 172 to be fixedly inserted.

[0026] See Figure 3 , 4 and Figure 5The pressure relief device 2 includes a pressure relief pipe 21 extending along the vertical direction D1 and communicating with the vent 15, two auxiliary pipes 22 disposed on the side of the pressure relief pipe 21 away from the hydrolysis furnace 1, and a sensor (not shown) disposed in one of the auxiliary pipes 22 for detecting the pressure or temperature of the corresponding area. The length W1 of the pipe body defined by the extension of the pressure relief device 2 along the vertical direction D1 is not less than the furnace height W2 defined by the extension of the outer shell body 161 of the hydrolysis furnace 1 along the vertical direction D1. In this embodiment, the inner diameter (diameter) of the pressure relief pipe 21 is between 15 and 25 inches.

[0027] The auxiliary pipe 22 extends radially along the pressure relief pipe 21 and connects to the exhaust port 15, and together they surround an axis L1 that is substantially perpendicular to the vertical direction D1. The auxiliary pipe 22 is used to connect to the air pollution treatment device so that the water vapor generated in the hydrolysis furnace 1 can be introduced into the air pollution treatment device. It is worth mentioning that the number of auxiliary pipes 22 can be adjusted to one or more as needed.

[0028] The pressure relief pipe 21 has a small-diameter pipe section 211 disposed on the top side of the hydrolysis furnace 1, a gradually expanding pipe section 212 connected to the top end of the small-diameter pipe section 211, and a large-diameter pipe section 213 connected to the top end of the gradually expanding pipe section 212. The gradually expanding pipe section 212 gradually expands from the side approaching the small-diameter pipe section 211 to the side approaching the large-diameter pipe section 213, and communicates between the small-diameter pipe section 211 and the large-diameter pipe section 213.

[0029] In actual operation, the material is placed into the reaction space 10 through the inlet 11. Then, the inlet 11, outlet 12, maintenance port 13, and vent 15 are closed. The temperature control device increases the temperature of the reaction space 10, and the pressure control device increases the pressure of the reaction space 10. Subsequently, the material in the reaction space 10 is stirred by the stirring module 17 to perform hydrolysis. Finally, water vapor and incomplete reaction byproducts are discharged to the pressure relief device 2 by opening the vent 15, and the main product and remaining byproducts are discharged by opening the outlet 12.

[0030] Therefore, this embodiment has the following advantages:

[0031] (i) By setting the pressure relief pipe 21 and the auxiliary pipe 22 of the pressure relief device 2, an appropriate buffer distance and a gradually expanding buffer space are provided, thereby preventing the by-products (such as particles) generated during the hydrolysis operation from overflowing into the air pollution treatment device in large quantities with the steam during the pressure relief operation. This not only reduces the load on the air pollution treatment device, but also reduces the probability of by-products contaminating the sensor.

[0032] (ii) By ensuring that the length W1 of the tube body defined by the pressure relief device 2 extending along the vertical direction D1 is not less than the height W2 of the furnace body defined by the outer shell body 161 of the hydrolysis furnace 1 extending along the vertical direction D1, the required buffer distance is provided to prevent byproducts (such as particles) generated during the hydrolysis operation from overflowing into the air pollution treatment device in large quantities with the steam, thereby reducing the load on the air pollution treatment device.

[0033] In summary, the high-temperature atomization hydrolysis system of the present invention, equipped with a pressure relief device, can prevent the large-scale overflow of its byproducts, and thus effectively achieves the purpose of the present invention.

[0034] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
