Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste heat recovery technology, specifically a waste heat recovery and recycling device for malt syrup production. Background Technology
[0002] Malt syrup is made from high-quality starch through liquefaction, saccharification, decolorization, filtration, and fine concentration. Maltose is the main component of the product. In the production process of malt syrup, the raw materials need to be cooked at high temperature and concentrated, which generates a lot of waste heat. Waste heat recovery and recycling devices are needed to utilize the waste heat.
[0003] Conventional malt syrup production equipment lacks the function of waste heat recovery, resulting in the direct release of large amounts of waste heat into the environment. This not only causes significant energy waste and increases production costs but also causes thermal pollution to the environment. Furthermore, the steam generated during the high-temperature cooking process usually contains some impurities, which may affect the heat transfer efficiency of the equipment and reduce the waste heat recovery effect if there is no filtration structure. Therefore, there is a need for a malt syrup production waste heat recovery and recycling device with a filtration structure. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a waste heat recovery and recycling device for malt syrup production. It has the advantages of being able to recover waste heat and having a filtration structure. This solves the problem that general malt syrup production equipment does not have the function of recovering waste heat, and a large amount of waste heat is directly emitted into the environment, which not only causes a great waste of energy and increases production costs, but also causes thermal pollution to the environment. In addition, the steam generated during the high-temperature cooking process usually contains some impurities. Without a filtration structure, it may affect the heat transfer efficiency of the equipment and reduce the waste heat recovery effect.

[0012] Compared with the prior art, this utility model provides a waste heat recovery and recycling device for malt syrup production, which has the following beneficial effects:
[0013] 1. Traditional malt syrup production equipment lacks the function of waste heat recovery, and the absence of a filtration structure reduces the effectiveness of waste heat recovery. This invention addresses this by introducing the high-temperature steam generated during malt syrup production into a heat exchanger to exchange heat with the cooling medium inside the heat exchange box. The steam, still relatively hot after heat exchange, is then stored in a heat storage tank, achieving full recovery and recycling of waste heat. This invention also filters impurities from the steam using a filter screen. The filter screen can be lifted by a handle periodically for cleaning or replacement.
[0014] 2. This waste heat recovery and recycling device integrates the functions of fully recovering and utilizing waste heat and has a filtration structure. The device can add or replenish cooling medium for heat exchange through the replenishment port. Opening the second valve will discharge the high-temperature cooling medium after absorbing waste heat and transport it to various heat utilization equipment, such as preheating raw materials and heating production water. After the cooling medium releases heat and its temperature decreases, it can be returned to the heat exchange box for recycling. The device has a controller installed on the outer surface of the heat storage tank. The controller can control the opening and closing of the valve and vacuum pump. Pressure and temperature sensors are also installed inside, which can be displayed in real time on the display screen. Attached Figure Description

[0019] 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.
[0020] Example 1:
[0021] Referring to Figures 1-2, a waste heat recovery and recycling device for malt syrup production includes a base plate 1. A production device 2, a heat exchange box 3, and a heat storage tank 4 are fixedly installed on the top of the base plate 1. A first connecting pipe 5 is fixedly connected to the right side of the production device 2. A heat exchanger 6 is installed inside the heat exchange box 3. The left side of the heat exchanger 6 is fixedly connected to the right side of the first connecting pipe 5. A second connecting pipe 7 is fixedly connected to the right side of the heat exchanger 6. The right side of the second connecting pipe 7 is fixedly connected to the left side of the heat storage tank 4. A vacuum pump 8 is fixedly installed on the right side of the heat storage tank 4. The input end of the vacuum pump 8 is fixedly connected to the inside of the heat storage tank 4. A third connecting pipe 9 is fixedly connected to the output end of the vacuum pump 8. A first valve 16 is fixedly installed inside the first connecting pipe 5. A replenishment port 17 is opened on the top of the heat exchange box 3. An outlet 18 is fixedly connected inside the heat exchange box 3. A second valve 19 is fixedly installed inside the outlet 18. A controller 20 is fixedly installed on the front surface of the heat storage tank 4. A pressure relief valve 21 is provided on the top of the heat storage tank 4.
[0022] Working principle: Malt syrup is produced in production equipment 2. During the production process, the high-temperature cooking and concentration of raw materials will generate a large amount of waste heat. First, the heat exchange box 3 is filled with cooling medium through the replenishment port 17. Then, the controller 20 opens the first valve 16 to introduce high-temperature steam into the heat exchanger 6 through the first connecting pipe 5 to exchange heat with the cooling medium in the heat exchange box 3. The steam after heat exchange is still relatively hot and enters the heat storage tank 4 through the second connecting pipe 7 for storage. The controller 20 opens the second valve 19 to discharge the high-temperature cooling medium after absorbing waste heat and deliver it to various heat utilization equipment, such as preheating raw materials and heating production water. After the cooling medium releases heat and its temperature decreases, it can be returned to the heat exchange box 3 for recycling. The controller 20 opens the vacuum pump 8 to discharge the steam in the heat storage tank 4 for secondary utilization, thus achieving the effect of fully utilizing waste heat.
[0023] Example 2:
[0024] Please refer to Figures 1 and 3. The first connecting pipe 5 is fixedly connected to a filter box 10. The filter box 10 has a slot 11 inside. The slot 11 has a block 12 inside. The inner surface of the block 12 is fixedly connected to a filter screen plate 13. The outer surface of the filter screen plate 13 is fixedly connected to a connecting block 14. A handle 15 is fixedly installed on the top of the connecting block 14.
[0025] Working principle: After steam is discharged from production equipment 2, it first passes through the first connecting pipe 5. Malt syrup may contain some solid particles, proteins and other components. During high-temperature cooking, these substances may volatilize with the steam. In addition, some impurities such as rust and dirt may also be mixed into the steam from equipment pipes. The filter screen 13 can filter these impurities. Through filtration, impurities in the steam can be effectively removed, ensuring the normal operation and efficiency of the waste heat recovery system. Every once in a while, the filter screen 13 can be lifted by the handle 15 through the connecting block 14. The clip 12 at the bottom of the cleaned filter screen 13 can be inserted into the slot 11 opened in the filter box 10 to complete the replacement.
