Description

Technical Field

[0001] This utility model relates to the field of humic acid production, and in particular to a cooling device for humic acid production. Background Technology

[0002] In the industrial production process of humic acid, steam cooling liquefaction is a key process that connects production links and ensures product quality. Its core requirement is to achieve efficient and uniform cooling of steam, while taking into account production flexibility and resource utilization efficiency.

[0003] Existing cooling equipment for humic acid production typically uses stainless steel condensers for cooling, with cooling water used to cool the steam inside the condenser pipes.

[0004] However, most existing condensers adopt a single pipeline design, which can only transport steam through a fixed path and cannot flexibly adjust the cooling path and cooling time according to the actual steam throughput. Therefore, a cooling device for humic acid production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a cooling device for humic acid production, which aims to improve the problems mentioned in the background art of the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cooling device for humic acid production, comprising a tank body, a top cover fixedly connected to the top of the tank body, an output pipe I fixedly connected through and to the top of the outer arc surface of the tank body, a short-range pipe fixedly connected to the top of the output pipe I, an output pipe II fixedly connected through and to the top of the outer arc surface of the tank body, a long-range pipe fixedly connected to the top of the output pipe II, the bottom ends of the output pipe I and the output pipe II being connected via a T-connector, the T-connector being provided in two sets, the other set of the T-connector being fixedly connected to the bottom ends of the short-range pipe and the long-range pipe, a switch valve rotatably connected to the outer arc surface of the T-connector, and a support column fixedly connected to the outer arc surface of the tank body.

[0007] As a further description of the above technical solution: A drain pipe is fixedly connected to the bottom of the tank, and a water supply pipe is fixedly connected through and to the top of the top cover. An inner ring pipe is fixedly connected to the output end of the water supply pipe, and an outer ring pipe is fixedly connected to the output end of the water supply pipe. Water outlet holes are opened on the outer arc surface of both the inner ring pipe and the outer arc surface of the outer ring pipe.

[0008] As a further description of the above technical solution: The bottom end of the short-range tube is inserted through and fixedly connected to the inner wall of the bottom of the outer arc surface of the tank.

[0009] As a further description of the above technical solution: The bottom end of the second output pipe is inserted through and fixedly connected to the inner wall of the bottom of the outer arc surface of the tank.

[0010] As a further description of the above technical solution: The inner tube is located inside the first output tube.

[0011] As a further description of the above technical solution: The outer ring tube is located outside the long-range tube.

[0012] This utility model has the following beneficial effects: 1. In this utility model, by setting up a dual-pipeline structure of short-path pipe and long-path pipe, and cooperating with two sets of three-way pipes with switching valves, the cooling path can be flexibly switched according to the actual processing volume and cooling requirements of humic acid vapor. For a small amount of vapor that needs to be cooled quickly, the short-path pipe passage is opened, and the residence time of the vapor is shortened by using the threaded pipe to achieve rapid liquefaction. For a large amount of vapor that needs to be fully cooled, the long-path pipe passage is switched to ensure deep liquefaction by extending the residence time of the vapor in the pipe.

[0013] 2. In this utility model, the double-layer annular layout of the inner and outer ring pipes corresponds to the inner side of the short-distance pipe and the outer side of the long-distance pipe, respectively. Combined with the inclined upward flat opening water outlet, the cooling medium is evenly sprayed on the outer wall of the two pipes in a water curtain shape, realizing all-round coverage of the pipes without dead angles, and avoiding the problem of uneven temperature caused by traditional single-sided spraying.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a cooling device for humic acid production, comprising a tank 1, which serves as the core load-bearing component of the cooling device, providing space for cooling water. A top cover 2 is fixedly connected to the top of the tank 1, and the top cover 2 and the tank 1 are designed to be sealed, effectively preventing leakage of materials or cooling media during the cooling process and ensuring the airtightness of the equipment operation. An output pipe 3 is fixedly connected through and to the top of the outer arc surface of the tank 1. The output pipe 3 is used to input steam from the humic acid production process and transport it to the inside of a short-distance pipe 4. A short-distance pipe 4 is fixedly connected to the top of the output pipe 3. The short-distance pipe 4 is configured as a threaded pipe, allowing the steam to spiral downwards inside the short-distance pipe 4. During the movement, the steam comes into contact with the short-distance pipe 4 through the cooling water, providing a cooling effect and thus liquefying the steam. An output pipe 5 is fixedly connected through and to the top of the outer arc surface of the tank 1. The output pipe 5 is used to transport steam from the humic acid production process to the inside of a long-distance pipe 6. The top of the output pipe 5 is fixedly connected to... A long-range pipe 6 is connected, which is longer than the short-range pipe 4, allowing for a longer cooling time for the steam inside the long-range pipe 6. Output pipe 1 3 and output pipe 2 5 are connected at their bottom ends by a tee pipe 7. Two sets of tee pipes 7 are provided; another set is fixedly connected to the bottom ends of the short-range pipe 4 and the long-range pipe 6. The tee pipe 7 serves to split and guide the flow, allowing adjustment of the material flow rate in the short-range pipe 4 and the long-range pipe 6 according to actual cooling requirements. A switch valve is rotatably connected to the outer arc surface of the tee pipe 7. 8. Switch valve 8 is existing technology. It can open and close the pipeline by rotation, thereby controlling the start and stop of material conveying. Support columns 9 are fixedly connected to the outer arc surface of tank body 1. The support columns 9 are evenly distributed at the bottom of the outer arc surface of tank body 1, providing stable support for the entire tank body 1 and ensuring the stability of the equipment during operation. The bottom end of short-distance pipe 4 passes through and is fixedly connected to the inner wall of the bottom of the outer arc surface of tank body 1. The bottom end of output pipe 2 5 passes through and is fixedly connected to the inner wall of the bottom of the outer arc surface of tank body 1.

[0018] Reference Figure 1 , Figure 4A drain pipe 10 is fixedly connected to the bottom of the tank body 1. The drain pipe 10 is mainly used to discharge the internal cooling water or excess cooling medium of the tank body 1. Its fixed connection to the bottom of the tank body 1 facilitates the natural drainage of liquid and reduces residue. A water supply pipe 11 is fixedly connected through the top of the top cover 2. The water supply pipe 11 serves as the input channel for the cooling medium. The design of penetrating the top cover 2 allows the cooling medium to be directly transported into the tank body 1. The fixed connection ensures the sealing of the cooling medium during transportation and prevents leakage. The water supply pipe 11 can be connected to the drain pipe 10. A filtration system and compressor are installed in the middle to achieve the effect of cooling water recycling. An inner ring pipe 12 is fixedly connected to the output end of the water supply pipe 11. The annular structure of pipe 12 allows the cooling medium to be evenly sprayed onto the outer wall of short-distance pipe 4 through water outlet 14. The output end of water supply pipe 11 is fixedly connected to outer ring pipe 13, which is located around the outer ring of long-distance pipe 6. This allows the cooling medium to be evenly sprayed onto the outer wall of long-distance pipe 6 through water outlet 14. Together with inner ring pipe 12, it forms an inner and outer double-layer structure, improving the uniformity of cooling. Water outlet 14 is provided on the outer arc surface of inner ring pipe 12 and outer arc surface of outer ring pipe 13. The water outlet 14 is set as a flat opening that is inclined upward, so that the sprayed cooling medium comes into contact with short-distance pipe 4 and long-distance pipe 6 in a water curtain shape. Inner ring pipe 12 is located inside short-distance pipe 4, and outer ring pipe 13 is located outside long-distance pipe 6.

[0019] Working principle: The steam generated during the humic acid production process first enters the equipment through output pipe 3 and output pipe 5, which are connected to a set of three-way pipes 7 at the top. Output pipe 3 is responsible for delivering the steam to the short-distance pipe 4, and output pipe 5 is responsible for delivering the steam to the long-distance pipe 6. The operator can adjust and switch between using the short-distance pipe 4 or the long-distance pipe 6 by rotating the switch valve 8 on the outer arc surface of the three-way pipe 7 according to the actual cooling needs. If a small amount of steam needs to be cooled quickly, open the switch valve 8 corresponding to the short-distance pipe 4 and close the switch valve 8 corresponding to the long-distance pipe 6. If a large amount of steam needs to be cooled sufficiently, adjust the switch valve 8 in the opposite direction. This allows the steam to be distributed to different pipes as needed.

[0020] Cooling water is input through a water supply pipe 11 that penetrates and is fixed to the top cover 2. Since the output end of the water supply pipe 11 is fixedly connected to the inner ring pipe 12 and the outer ring pipe 13 respectively, the cooling medium flows into both pipes simultaneously. Because the inner ring pipe 12 is located inside the short-distance pipe 4 and the outer ring pipe 13 is located outside the long-distance pipe 6, and both have upward-sloping, flat-opening water outlet holes 14 on their outer arc surfaces, the cooling medium is sprayed in a water curtain-like pattern through the water outlet holes 14, evenly covering the outer walls of the short-distance pipe 4 and the long-distance pipe 6. The steam diverted to the short-distance pipe 4... The short-circuit pipe 4 is a threaded pipe that spirals downwards along the pipe. During this process, it comes into contact with the water curtain-like cooling medium sprayed by the inner ring pipe 12, and gradually liquefies after absorbing heat. The steam diverted to the long-circuit pipe 6, because the long-circuit pipe 6 is longer than the short-circuit pipe 4, stays in the pipe for a longer time, and continues to come into contact with the water curtain-like cooling medium sprayed by the outer ring pipe 13, fully absorbing heat and achieving deep liquefaction. The cooling medium that has completed heat absorption moves downwards along the inner wall of the tank 1, collects at the bottom of the tank 1, and is discharged through the drain pipe 10 fixed at the bottom of the tank 1. The discharged cooling medium can be connected to the water supply pipe 11 through a pipeline. A filtration system and compressor are installed in the middle of the connecting pipeline. After purification and temperature regulation, the cooling medium is reintroduced to the water supply pipe 11, realizing the recycling of the cooling medium. Then, the liquefied humic acid liquid in the short-circuit pipe 4 and the long-circuit pipe 6 is discharged from the equipment through another set of tee pipes 7 at the bottom and enters the subsequent stage.
