Description

Technical Field

[0001] This utility model relates to the field of spray device technology, specifically to a liquid ammonia loading spray device. Background Technology

[0002] When transporting liquid ammonia over long distances, the transport vehicles need to be parked at the liquid ammonia loading station. During loading, a filling arm is used to fill the tank truck with liquid ammonia. To ensure the safety of the loading operation, a spray system needs to be installed at the liquid ammonia loading station. This system can spray the tank of the tank truck to reduce its temperature and prevent safety hazards caused by high temperatures. It can also dilute and absorb leaked ammonia gas in the event of a leak, thus ensuring the safety of the loading station. The cooling water used for the cooling spray during loading can be recycled and reused, while the spray water used to absorb leaked liquid ammonia needs to be centrally collected and treated. Therefore, how to quickly treat the spray water is of paramount importance to ensuring the safe operation of liquid ammonia loading. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-2 As shown, this utility model embodiment provides a liquid ammonia loading spray device, including a water storage tank 1 placed below the ground at the liquid ammonia loading station. A grid plate 2 is provided on the top of the water storage tank 1. A water distribution tank 3 is provided on the ground on one side of the water storage tank 1. The water distribution tank 3 is suspended above the ground. Several water distribution pipes 4 are evenly distributed on the water distribution tank 3. The water distribution pipes 4 are arranged facing the side of the vehicle parking position. Several spray nozzles are evenly distributed on the water distribution pipes 4. A recovery tank 5 is also provided on the ground on one side of the water storage tank 1. A first water pump 6 and a second water pump 7 are provided in the water storage tank 1. The first water pump 6 is connected to the water distribution tank 3 through a pipeline. The second water pump 7 is connected to the recovery tank 5 through a pipeline. The water distribution tank 4 is also connected to the water supply pipeline through a water pipe 8. A control valve 9 is provided on the water pipe 8. An ammonia concentration sensor is also provided around the water storage tank 1. In conjunction with the control cabinet and PLC control system, the two water pumps and the control valve 9 are driven to work.

[0020] A filter assembly is installed inside the water storage tank 1 at the position below the corresponding grid plate 2.

[0021] The filter assembly includes a partition 10 disposed in a water storage tank 1, with a plurality of drain outlets evenly distributed on the partition 10, and a filter cylinder disposed below the partition 10 at the position corresponding to each drain outlet.

[0022] The filter cartridge includes a cartridge base 11 disposed at the bottom of the partition plate 10, and a mesh cylinder 12 with a top opening disposed at the bottom of the cartridge base 11. The top opening of the mesh cylinder 12 is fixedly connected to the bottom opening of the cartridge base 11.

[0023] The top of the partition plate 10 is provided with a bevel groove 13 that is wider at the top and narrower at the bottom at the position corresponding to each drain outlet. The upper edge of the cylinder seat 11 is located at the lowest end of the bevel groove 13. The bevel groove 13 allows the spray water flowing down to quickly flow into the filter cylinder and then into the water storage tank 1 through the filter cylinder.

[0024] The baffle 10 works in conjunction with the filter cylinder to filter the spray water flowing down, thereby preventing dust and other particles from entering the water storage tank 1 and thus protecting the water pump in the water storage tank 1. Impurities in the spray water flowing down are blocked by the mesh cylinder 12 at the bottom of the filter cylinder, and the filtered spray water flows down along the mesh of the mesh cylinder 12.

[0025] Several support beams 14 are evenly distributed inside the water storage tank 1 below the corresponding partition 10. The partition 10 is installed above the support beams 14, and the support beams 14 support the partition 10.

[0026] The partition 10 is supported below the grid plate 2.

[0027] An installation bracket 15 is set on the ground, and a water distribution tank 3 is set above the installation bracket 15.

[0028] A spray head 16 is installed at the spray outlet of the water distribution pipe 4.

[0029] The working principle of this utility model is as follows: When the tanker truck is parked above the grating plate 2, and liquid ammonia is being loaded, the first water pump 6 can be controlled by the control cabinet and the control system to pump the spray water in the water storage tank 1 to the water distribution tank 3. Then, the spray head 16 on the water distribution pipe 4 sprays cooling water onto the tank body of the tanker truck. The cooling water flowing down from the spray falls onto the grating plate 2 on the ground. Then, the cooling water flows into the water storage tank 1 for recycling through the mesh on the grating plate 2 and the filter cylinder on the partition plate 10. A water level monitoring probe can also be installed in the water storage tank 1. When the water level in the water storage tank 1 is too low, the water level monitoring probe sends a signal to the control system and activates the control valve 9 so that the water supply pipeline sends cooling water into the water distribution tank 3 through the water pipe 8. The water storage tank 1 can also be equipped with a water replenishment pipe to replenish cooling water into the water storage tank 1.

[0030] When ammonia leaks during filling, the ammonia concentration sensor will activate and send a signal to the control system, causing the control system to open the control valve 9, allowing cooling water in the water supply pipeline to enter the water distribution tank 3. The cooling water is then sprayed out through the water distribution pipe 4 to absorb the leaked ammonia. The cooling water that has absorbed the ammonia also flows into the water storage tank 1 through the grid plate 2. Then, the second water pump 7 starts and transports the cooling water that has absorbed the ammonia in the water storage tank 1 to the recovery tank 5 for centralized recycling and treatment.

[0031] Under the control of the control system, the two water pumps can perform spraying operations for different scenarios, thereby dealing with various problems that may occur during liquid ammonia filling.

[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
