Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically a waste heat recovery device for boric acid production. Background Technology

[0002] Boric acid is an inorganic compound with the chemical formula H3BO3. It is a white crystalline powder with a slippery feel and no odor. It is widely used in the glass industry to improve the heat resistance and transparency of glass products, increase mechanical strength, and shorten melting time. A large amount of waste heat is generated during the boric acid processing. If this waste heat cannot be effectively recovered and utilized, it will result in energy waste. Therefore, it is necessary to use a recovery device to recover the waste heat.

[0003] Conventional waste heat recovery devices for boric acid production cannot fully recover waste heat, resulting in low energy utilization and energy waste. Furthermore, if adjustments are not made in a timely manner during the recovery process, the recovery efficiency will also be affected. Therefore, there is a need for a waste heat recovery device for boric acid production with higher waste heat recovery and utilization rates and the ability to make timely adjustments based on the recovery situation.

It has the advantages of higher waste heat recovery and utilization rate and timely adjustment according to the recovery situation. It solves the problems of general waste heat recovery devices for boric acid production failing to fully recover waste heat, resulting in low energy utilization and energy waste. Furthermore, if the recovery process cannot be adjusted in a timely manner according to the situation, the recovery efficiency will also be affected.

[0011] Compared with the prior art, this utility model provides a waste heat recovery device for boric acid production, which has the following beneficial effects:

[0012] 1.

The design of this utility model allows high-temperature boric acid solution or steam and other waste heat carriers to enter the waste heat pipe inside the heat exchange shell through the waste heat channel inlet. At the same time, cold water and other heat exchange media enter the heat exchange medium pipe through the heat exchange medium channel inlet under the drive of the circulation pump, so that the waste heat carrier and heat exchange medium can fully exchange heat in the heat exchange shell. This utility model has temperature sensors and flow meters installed at key parts such as the waste heat pipe and the inlet and outlet of the heat exchange shell to monitor the temperature and flow data of each part in real time.

[0018] 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.

[0019] Example 1:

[0020] Referring to Figures 1-3, a waste heat recovery device for boric acid production includes a base plate 1. A boric acid reaction vessel 3 is fixedly connected to the top of the base plate 1 via support legs 2. A waste heat channel inlet 4 is fixedly connected to the bottom of the boric acid reaction vessel 3. A heat exchange shell 6 is fixedly connected to the top of the base plate 1 via support blocks 5. A waste heat pipe and a heat exchange medium pipe are respectively arranged inside the heat exchange shell 6. The bottom of the waste heat channel inlet 4 is fixedly connected to the interior of the waste heat pipe. A waste heat channel outlet 7 is fixedly connected to the end of the waste heat pipe away from the waste heat channel inlet 4. A booster pump 8 is arranged at the top of the waste heat channel outlet 7. A connecting pipe 9 is fixedly connected to the output end of the booster pump 8. The end of the connecting pipe 9 away from the booster pump 8 is fixedly connected to the interior of the boric acid reaction vessel 3. A heat exchange medium channel outlet 10 is fixedly connected to the left side of the heat exchange medium pipe, and a heat exchange medium channel inlet 11 is fixedly connected to the right side of the heat exchange medium pipe. A glass 15 is fixedly installed on the outer surface of the boric acid reaction vessel 3. A feeding port 16 is opened at the top of the boric acid reaction vessel 3.

[0021] Working principle: First, boric acid raw material and reaction solution are added through feed port 16. After the reaction, the controller 13 opens the regulating valve 12 to allow the high-temperature boric acid solution or steam and other waste heat carriers to enter the waste heat pipe inside the heat exchange shell 6 through the waste heat channel inlet 4. At the same time, cold water and other heat exchange media enter the heat exchange medium pipe through the heat exchange medium channel inlet 11 under the drive of the circulation pump. This allows the waste heat carrier and the heat exchange medium to fully exchange heat in the heat exchange shell 6. The heat from the waste heat carrier is transferred to the heat exchange medium, raising its temperature. After heat exchange, the boric acid solution returns to the boric acid reaction tank 3 under the action of the booster pump 8, while the heat exchange medium exits from the heat exchange medium channel outlet 10 under the drive of the circulation pump. Through circulation, the heat exchange medium is heated to the boiling point to generate steam. The steam enters the steam generator for further pressurization and then drives the steam turbine to rotate. The steam turbine drives the generator to generate electricity, which can be transmitted to the factory's internal power grid for reuse. It can be used to drive motors, lighting systems, etc. in the boric acid production equipment.

[0022] In this implementation plan: the heat exchanger is an existing structure, which is common knowledge in the field. It is only used and not modified, so the internal piping connection is not shown.

[0023] Example 2:

[0024] Please refer to Figures 1-3. A regulating valve 12 is fixedly installed inside the waste heat channel inlet 4. A bracket 14 is fixedly connected to the top of the base plate 1. A controller 13 is fixedly installed on the front surface of the bracket 14. The inside of the bracket 14 is fixedly connected to the outer surface of the booster pump 8.

[0025] Working principle: Temperature sensors and flow meters monitor the temperature and flow data of each part in real time and transmit the data to controller 13. Controller 13 can make timely adjustments based on the waste heat recovery situation. For example, when the temperature of the waste heat carrier in the waste heat pipe is too high, controller 13 can appropriately increase the opening of regulating valve 12 to accelerate the flow of the waste heat carrier and improve heat exchange efficiency. When the temperature at the outlet 10 of the heat exchange medium channel in the heat exchange shell 6 does not reach the set value, controller 13 can increase the speed of the circulating pump to increase the flow of the heat exchange medium and enhance the heat exchange effect.
