[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only the embodiments of the present utility model, and for those of ordinary skill in the art, other drawings can be obtained according to the provided drawings without creative efforts.

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] Refer to Figure 1 , the embodiment of the present utility model provides a gypsum board production system, including a gypsum raw material warehouse 8 and a flue gas discharge pipeline. The gypsum raw material warehouse 8 is used to provide a storage space for storing gypsum raw materials. Specifically, the gypsum raw material warehouse 8 can be set in the form of buildings such as greenhouses or warehouses. The flue gas discharge pipeline is connected to a gypsum board production workshop (not shown in the figure) and a tail gas chimney 4. It is easy to understand that the flue gas generated during the production of gypsum boards reaches the tail gas chimney 4 through the flue gas discharge pipeline, and necessary environmental protection equipment is arranged on the flue gas discharge pipeline for environmental protection treatment of the flue gas.
[0024] The gypsum board production system further includes a heat exchanger 2 and a ventilation pipeline. The ventilation pipeline is connected to the heat exchanger 2 and the gypsum raw material warehouse 8. The heat exchanger 2 has a first channel and a second channel for heat exchange with each other. Among them, the first channel is connected to the flue gas discharge pipeline, and the second channel is connected to the ventilation pipeline. That is, the first channel is used for the flue gas to flow through, and the second channel is used for the air to flow through. During the production process, the air passes through the heat exchanger 2 and then reaches the gypsum raw material warehouse 8 along the ventilation pipeline. Since the air exchanges heat with the flue gas at the heat exchanger 2, the air is heated to a certain temperature and finally enters the gypsum raw material warehouse 8 in the form of hot air. The hot air can perform a certain degree of drying treatment on the gypsum raw materials stored in the gypsum raw material warehouse 8, thereby reducing the attached water content of the gypsum raw materials. It is easy to understand that if the gypsum raw materials contain a large amount of attached water, these attached waters will cause an increase in coal consumption during the raw material drying process in the drying workshop. However, the gypsum board production system of the present utility model performs a certain degree of drying treatment on the gypsum raw materials in the gypsum raw material warehouse 8. Therefore, it is beneficial to reduce the coal consumption in the drying workshop and achieve the purpose of energy conservation and consumption reduction.
[0025] At the same time, since the flue gas exchanges heat with the air at the heat exchanger 2, the temperature of the flue gas decreases. After the heat of the flue gas is displaced, it is finally used to dry the gypsum raw materials stored in the gypsum raw material warehouse 8, thereby reducing heat loss and waste. Moreover, the flue gas at a lower temperature is beneficial to reducing the evaporation amount in the desulfurization tower (not shown in the figure), thereby avoiding an increase in the whiteness of the tail gas; after the temperature of the flue gas decreases, it is beneficial to increase the residence time of the flue gas in the desulfurization tower and improve the desulfurization efficiency.
[0026] In a preferred embodiment, the gypsum board production system further includes a temperature monitoring device located in the gypsum raw material storage 8. The temperature monitoring device can monitor the temperature in the gypsum raw material storage 8, and the temperature data in the gypsum raw material storage 8 can be used to guide the setting of the ventilation volume.
[0027] In a preferred embodiment, the gypsum board production system further includes a humidity monitoring device 7 located in the gypsum raw material storage 8. The humidity monitoring device 7 can monitor the humidity in the gypsum raw material storage 8, and the humidity data in the gypsum raw material storage 8 can be used to guide the setting of the ventilation volume.
[0028] As Figure 1 shown, in this embodiment, the gypsum board production system may further include a spray washing device 3. The nozzle of the spray washing device 3 is located in the first channel of the heat exchanger 2. The spray washing device 3 can wash the inner wall of the first channel, thereby removing the dust on the inner wall, which is beneficial to avoiding the blockage of the heat exchanger 2 by the dust particles in the flue gas. Specifically, the heat exchanger 2 can be set as a tubular heat exchanger or a plate heat exchanger.
[0029] In this embodiment, the gypsum board production system may further include a first induced draft fan 5. The first induced draft fan 5 is arranged on the ventilation pipeline and is used to drive the gas in the ventilation pipeline along the direction from the heat exchanger 2 to the gypsum raw material storage 8. In order to achieve a better ventilation and drying effect, the aforementioned temperature monitoring device and / or humidity monitoring device 7 can be electrically connected to the first induced draft fan 5, and the air volume of the first induced draft fan 5 can be controlled by using the temperature and humidity data in the gypsum raw material storage 8 as feedback, thereby realizing the control of the temperature and humidity in the gypsum raw material storage 8.
[0030] In a preferred embodiment, the gypsum board production system further includes a temperature measuring device 6 arranged on the ventilation pipeline and used to measure the temperature of the air in the ventilation pipeline. Further preferably, the temperature measuring device 6 is located downstream of the first induced draft fan 5 on the ventilation pipeline. For example, the temperature measuring device 6 can be arranged at a position on the ventilation pipeline close to the gypsum raw material storage 8.
[0031] As Figure 1 shown, in this embodiment, the gypsum board production system may further include a second induced draft fan 1. The second induced draft fan 1 is arranged on the flue gas discharge pipeline and is used to drive the flue gas in the flue gas discharge pipeline along the direction from the gypsum board production workshop to the tail gas chimney 4. Specifically, the second induced draft fan 1 can be located upstream of the heat exchanger 2 on the flue gas discharge pipeline. For example, the second induced draft fan 1 can be arranged between the electrostatic precipitator (not shown in the figure) and the heat exchanger 2, that is, the flue gas first passes through the electrostatic precipitator, and then successively passes through the second induced draft fan 1 and the heat exchanger 2 and goes to the tail gas chimney 4.
[0032] In the present specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts among the various embodiments can be referred to each other.
[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
