Description

Technical Field

[0001] This utility model relates to the field of flue gas denitrification technology, specifically to an automated ammonia evaporation system. Background Technology

[0002] Ammonia evaporation systems are mainly used to convert liquid ammonia into gaseous ammonia. They are widely used in SCR denitrification systems, chemical process cooling, and wastewater treatment. Depending on the heat source, they are mainly divided into two types: steam-heated and hot-air-heated.

[0003] Chinese utility model patent CN214050483U discloses an ammonia evaporator, belonging to the field of alkaline etching solution circulation. It includes an evaporator and a heating tank. The bottom of the evaporator is fixedly connected to the bottom of the heating tank via a liquid delivery pipe. A sampling tube is fixedly fitted onto one side of the bottom of the evaporator. A feed pipe and a return gas pipe are fixedly connected to one side and the top of one side of the evaporator, respectively. A glass tube and an outlet gas pipe are fixedly fitted onto the other side and the top of the other side of the evaporator. This ammonia evaporator, by incorporating an evaporator, heating tank, liquid delivery pipe, connecting pipe, outlet gas pipe, and outlet check valve, facilitates the evaporation of ammonia into ammonia gas during alkaline etching and transports the ammonia gas to the alkaline etching solution circulation system. This avoids the problems of large volume expansion and explosion that can easily occur when directly adding ammonia or liquid ammonia to the alkaline etching solution circulation system, thus improving the safety of ammonia replenishment during alkaline etching solution replenishment.

[0004] However, during the implementation of the relevant technologies, the following problems were found in the above solutions: poor safety protection effect, inability to effectively control major leakage accidents, and when pipelines rupture or valves are damaged, a large amount of ammonia gas will be released. This high concentration of ammonia gas will spread rapidly and uncontrollably, which can easily cause mass injuries to personnel on site and spread to other areas of the plant and even outside the plant, causing safety incidents. Utility Model Content

[0005] This invention proposes an automated ammonia evaporation system, which solves the problems of poor safety protection in related technologies, inability to effectively control major leakage accidents, and the release of large amounts of ammonia gas when pipelines rupture or valves are damaged. These high-concentration ammonia gases will spread rapidly and uncontrollably, which can easily cause mass injuries to personnel on site and spread to other areas of the plant or even outside the plant, causing safety incidents.

[0006] The technical solution of this utility model is as follows: An automated ammonia evaporation system, comprising: The protective enclosure and the evaporator and heating tank housed within it; Ammonia detectors and fire detectors are symmetrically and fixedly installed on the inner top wall of the protective box for detection. The drive assembly is located on top of the protective enclosure; A T-shaped tube fixedly mounted on the drive assembly; Multiple nozzles are horizontally arranged and fixedly installed on the T-shaped tube; Water supply components are installed in the rack at the rear of the protective box; And a hose fixedly connected to the water supply assembly, with the other end of the hose fixedly connected to the T-shaped pipe.

[0007] Preferably, a support frame is fixedly installed on the inner bottom wall of the protective box, and both the evaporator and the heating tank are located on top of the support frame; An exhaust fan is fixedly installed on the inner top wall of the support frame via a fixing bracket. The exhaust end of the exhaust fan is fixedly connected to a connecting pipe. A storage box is provided in the placement rack on the rear side of the protective box, and the other end of the connecting pipe is connected to the storage box.

[0008] Preferably, the protective box has rectangular openings on both sides, and two sponges are symmetrically arranged on the inner side of the rectangular openings, and the sponges are fixedly connected to the protective box.

[0009] Preferably, the drive assembly includes two L-shaped plates symmetrically fixedly installed on the top of the protective box, with a screw rod disposed between the two L-shaped plates, and both ends of the screw rod being rotatably connected to the L-shaped plates; A first inverted U-shaped bracket is threaded onto the outer wall of the screw. A second inverted U-shaped bracket is fixedly installed at both ends of the first inverted U-shaped bracket through the strip-shaped opening at the top of the protective box. The T-shaped tube is fixedly installed on the inner side of the second inverted U-shaped bracket. A motor is fixedly mounted on one of the L-shaped plates, and the output end of the motor is fixedly connected to the screw.

[0010] Preferably, two linear slide rails are symmetrically fixedly installed on the top of the protective box, and the first inverted U-shaped frame is slidably connected to the linear slide rails by a slider.

[0011] Preferably, a protective cover is fixedly installed on the top of the protective box, and ventilation openings are provided on both sides of the protective cover. A filter screen is provided inside the ventilation opening, and the filter screen is fixedly installed on the protective cover.

[0015] The working principle and beneficial effects of this utility model are as follows: The inside of the protective box is monitored by an ammonia detector and a fire detector. Once a leak or fire is detected, the controller on the outside of the protective box automatically activates the water supply component and the drive component. Then, the water supply component supplies water to the T-shaped pipe through a hose and sprays it out from the nozzle. At the same time, the drive component moves the T-shaped pipe to achieve large-area spraying, which can extinguish the fire or quickly absorb and dissolve the leaked high-concentration ammonia gas in water to form dilute ammonia water, which is then discharged to an external collection box connected to the drain pipe, thus preventing large-scale spread and controlling the impact of the accident within the plant area.

[0016] The ammonia gas leaking from the protective box can be extracted by the exhaust fan. Then, with the help of the connecting pipe, the extracted ammonia gas can be transported to the storage box for storage, thereby further improving the safety protection effect and preventing the ammonia gas from accumulating in the confined or poorly ventilated space. This fundamentally eliminates the acute poisoning accident and potential explosive environment caused by the concentration reaching the dangerous limit. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0021] Please see Figure 1 - Figure 6 An automated ammonia evaporation system includes: Protective box 1 and evaporator 2 and heating tank 3 installed inside protective box 1; Ammonia detector 4 and fire detector 5 are symmetrically and fixedly installed on the inner top wall of the protective box 1 for detection. The drive assembly 6 is located on the top of the protective box 1; T-shaped tube 7 is fixedly installed on drive assembly 6; Multiple nozzles 8 are horizontally arranged and fixedly installed on the T-shaped tube 7; Water supply component 9 is installed in the shelf behind the protective box 1; And a hose 10 fixedly connected to the water supply assembly 9, with the other end of the hose 10 fixedly connected to the T-shaped pipe 7.

[0022] This utility model provides an automated ammonia evaporation system. In use, an ammonia detector 4 and a fire detector 5 are used for detection within the protective box 1. When the ammonia detector 4 and the fire detector 5 detect an ammonia leak or fire in the protective box 1, they connect and transmit a signal to a controller outside the protective box 1. The controller then automatically activates the water supply component 9 and the drive component 6. The activated water supply component 9 supplies water to the T-shaped pipe 7 through the hose 10. The water in the T-shaped pipe 7 is then sprayed out from the nozzle 8. Simultaneously, the drive component 6 moves the T-shaped pipe 7 and the nozzle 8, thereby achieving large-area spraying. This can extinguish fires or quickly absorb and dissolve leaked high-concentration ammonia in water to form dilute ammonia water, which is then drained to an external collection box connected to the drain pipe 19, preventing large-scale spread and controlling the impact of the accident within the device area.

[0023] Furthermore, rectangular openings are provided on both sides of the protective box 1, and two sponges 15 are symmetrically arranged on the inner side of the rectangular openings, and the sponges 15 are fixedly connected to the protective box 1.

[0024] Specifically, the rectangular opening on the protective box 1 allows the feed pipes of the evaporator 2 and the heating tank 3 to be connected to the external pipes, ensuring that materials such as ammonia can enter the evaporator 2 and the heating tank 3. At the same time, the sponge 15 can seal the rectangular opening, effectively preventing leaked ammonia from being discharged from the rectangular opening without affecting the connection between the external pipes and the feed pipes of the evaporator 2 and the heating tank 3.

[0025] Furthermore, the drive assembly 6 includes two L-shaped plates 61 symmetrically fixedly installed on the top of the protective box 1, with a screw 62 provided in the middle of the two L-shaped plates 61, and both ends of the screw 62 being rotatably connected to the L-shaped plates 61. A first inverted U-shaped bracket 63 is threaded onto the outer wall of the screw 62. The two ends of the first inverted U-shaped bracket 63 pass through the strip-shaped opening at the top of the protective box 1 and are fixedly installed with a second inverted U-shaped bracket 64. The T-shaped tube 7 is fixedly installed on the inner side of the second inverted U-shaped bracket 64. A motor 65 is fixedly mounted on one of the L-shaped plates 61, and the output end of the motor 65 is fixedly connected to the screw 62.

[0026] Specifically, the motor 65 drives the screw 62 to rotate, and the rotating screw 62 then drives the first inverted U-shaped frame 63 connected to it by threads, so that the second inverted U-shaped frame 64 can drive the T-shaped tube 7 to move, thereby enabling the nozzle 8 to achieve large-area spraying.

[0027] Furthermore, two linear slide rails 20 are symmetrically fixedly installed on the top of the protective box 1, and the first inverted U-shaped frame 63 is slidably connected to the linear slide rails 20 via a slider.

[0028] Specifically, the linear guide rail 20 enables the screw 62 to stably drive the first inverted U-shaped frame 63 to move, while also preventing the screw 62 from contacting the edge of the top strip opening of the protective box 1, thereby reducing the wear of the first inverted U-shaped frame 63.

[0029] Furthermore, a protective cover 16 is fixedly installed on the top of the protective box 1. Ventilation openings are provided on both sides of the protective cover 16. A filter screen 17 is provided inside the ventilation opening and is fixedly installed on the protective cover 16.

[0030] Specifically, the protective cover 16 can protect the strip opening at the top of the protective box 1, preventing debris from entering the interior of the protective box 1 through the strip opening. At the same time, the ventilation holes and filter screen 17 on the protective cover 16 can ensure the circulation of air inside and outside the protective box 1.

[0031] Furthermore, multiple U-shaped frames 18 are arranged inside the protective box 1, and both ends of the U-shaped frames 18 are fixedly connected to the protective box 1. The U-shaped frames 18 are located below the hose 10.

[0032] Specifically, the U-shaped bracket 18 can block the hose 10, preventing the middle part of the hose 10 from drooping and contacting the evaporator 2 and the heating tank 3.

[0033] Furthermore, a drain pipe 19 is fixedly installed on the rear side of the protective box 1, and a solenoid valve is provided on the outer wall of the drain pipe 19.

[0034] Specifically, open the valve on the drain pipe 19 to allow the dilute ammonia water on the bottom wall of the protective box 1 to be drained from the drain pipe 19 to the external collection box connected to the drain pipe 19.

[0035] Furthermore, the water supply assembly 9 includes a water tank 91 located in the shelf behind the protective box 1. A water pump 92 is fixedly installed on the top of the water tank 91, and a hose 10 is fixedly connected to the output end of the water pump 92. A water pump pipe 93 is fixedly connected to the input end of the water pump 92, and the other end of the water pump pipe 93 extends to the inside of the water tank 91.

[0036] Specifically, water is drawn from the water tank 91 by the water pump 92 and the water pipe 93, and then the drawn water is transported to the T-shaped pipe 7 through the hose 10, so that the interior of the protective box 1 can be sprayed. Example

[0037] Based on Embodiment 1, in this embodiment: a support frame 11 is fixedly installed on the inner bottom wall of the protective box 1, and the evaporator 2 and the heating tank 3 are both located on the top of the support frame 11. An exhaust fan 12 is fixedly installed on the inner top wall of the support frame 11 by a fixing bracket. A connecting pipe 13 is fixedly connected to the exhaust end of the exhaust fan 12. A storage box 14 is provided in the placement rack on the rear side of the protective box 1, and the other end of the connecting pipe 13 is connected to the storage box 14.

[0038] The technical solution provided in this embodiment is as follows: when the controller on the protective box 1 starts the water supply component 9 and the drive component 6, the exhaust fan 12 is started at the same time, so that the exhaust fan 12 can extract the ammonia gas leaking from the protective box 1. Then the extracted ammonia gas is transported to the storage box 14 through the connecting pipe 13 for storage, thereby further improving the safety protection effect, preventing ammonia gas from accumulating in a closed or poorly ventilated space, and fundamentally eliminating acute poisoning accidents and potential explosive environments caused by the concentration reaching the dangerous limit.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
