Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ammonia treatment, in particular to an ammonia emission absorption device. Background Art
[0002] Ammonia, a common gas in industrial production, requires strict control and handling due to its volatility and toxicity. If not properly handled or leaks during the production process, it can cause serious environmental pollution and health risks. Therefore, effective measures must be taken to collect and treat it to prevent its adverse effects on the environment and health.
[0003] Currently, ammonia is commonly treated in industry by dissolving it in water to form ammonia water. This is because ammonia has a high solubility in water, which facilitates subsequent processing. The usual operation method is to pass water into an ammonia tank or pass ammonia into water. However, the dissolution of ammonia in water is an exothermic reaction, which means that the dissolution process releases heat, causing the dissolution rate to slow as the temperature rises. In addition, as the concentration of the water surface in contact with ammonia increases, a very concentrated ammonia water layer will form. This may hinder the contact between water and ammonia in other parts of the body, affecting the overall treatment efficiency. Utility Model Content
[0004] In order to solve the above problems, the utility model proposes an ammonia emission absorption device which further accelerates the speed of ammonia dissolving in water, effectively reduces the temperature and prevents the formation of a concentrated ammonia water layer.
[0005] In order to solve the above-mentioned technical problems, the technical solution proposed in the present invention is: an ammonia emission absorption device, comprising a treatment box, an air inlet pipe connected to one side of the treatment box, an electric-controlled valve 1 being provided on the air inlet pipe, a stirring shaft being rotatably connected inside the treatment box, a plurality of stirring blades being connected to the stirring shaft, the stirring shaft being driven by a reduction motor fixed to the bottom surface of the treatment box, a cooling pipe running through the treatment box being connected to the bottom surface of the treatment box, a spray plate being connected to the upper wall of the treatment box, a water inlet pipe connected to the spray plate being connected above the treatment box, a water pump being connected to the water inlet pipe, a water outlet pipe being connected to the bottom of the treatment box, an electric-controlled valve 2 being provided on the water outlet pipe, and an air bag being connected to one side of the treatment box.
[0006] Furthermore, the air intake pipe is a multi-section arc-shaped pipe.
[0007] Based on the above characteristics, part of the ammonia gas can be temporarily stored, so that the temporarily stored ammonia gas can be dissolved as the water temperature drops after the introduction of ammonia gas is stopped, thereby improving the utilization rate of water.
[0008] Furthermore, the stirring blade is in the shape of an arc plate.
[0009] Based on the above characteristics, the contact area with water can be increased, further promoting the rapid dissolution of ammonia in water.
[0010] Furthermore, a plurality of evenly distributed spray heads are provided below the spray plate.
[0011] Based on the above characteristics, the evenly distributed spray heads can ensure that water is fully in contact with ammonia during the spraying process, thereby improving the efficiency and uniformity of ammonia dissolving in water.
[0012] Furthermore, a temperature monitor is connected to the side wall of the processing box.
[0013] Based on the above characteristics, the ammonia water in the treatment box can be monitored in real time, so as to adjust the cooling efficiency of the cooling pipe to ensure that the water temperature is maintained at a low temperature so that the ammonia gas can dissolve in the water quickly.
[0014] Furthermore, a water level monitor is connected to the inner wall of the processing box below and near the air inlet pipe port, and a waterproof groove is connected to the inner wall of the processing box between the air inlet pipe port and the water level monitor.
[0015] Based on the above characteristics, the water level monitor can be used in conjunction with the waterproof tank to monitor the water level, facilitate timely control of water inflow, and effectively prevent water from entering the intake pipe and causing pollution.
[0016] Compared with the prior art, the advantages of the present invention are: the arrangement of the spray plate and the spray heads evenly distributed thereunder can spray water into the treatment box and combine it with ammonia, which is beneficial to increasing the speed at which ammonia dissolves in water; the arrangement of the cooling pipe can continuously cool the water in the treatment box to ensure that the water is maintained at a low temperature, avoiding a decrease in the ammonia dissolution rate as the water temperature rises as the ammonia dissolves; in addition, the arrangement of the stirring blades can also promote the mixed dissolution of ammonia and water, and can also avoid the formation of a layer of ammonia water with a higher concentration, thereby ensuring that the ammonia dissolves evenly in the water and improving the dissolution rate.

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.
[0023] Combined with attachment Figure 1 , Attachment Figure 2 An ammonia emission absorption device includes a treatment box 1, one side of which is connected to an air intake pipe 2, and an electric control valve 3 is provided on the air intake pipe 2. The air intake pipe 2 is a multi-section arc pipe, which can temporarily store some ammonia, so that the temporarily stored ammonia can be dissolved as the water temperature drops after the ammonia is stopped, thereby improving the utilization rate of water.
[0024] Combined with attachment Figure 1 , Attachment Figure 2 A stirring shaft 4 is rotatably connected inside the treatment box 1, and a number of stirring blades 5 are connected to the stirring shaft 4. The stirring shaft 4 is driven by a reduction motor 6 fixed to the bottom surface of the treatment box 1. The stirring blades 5 are arc-shaped plates, which can increase the contact area with water and further promote the rapid dissolution of ammonia in water.
[0025] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 A cooling pipe 7 is connected to the bottom surface of the treatment box 1 and passes through the treatment box 1. A temperature monitor 15 is connected to the side wall of the treatment box 1, which can monitor the ammonia water in the treatment box 1 in real time, thereby adjusting the refrigeration efficiency of the cooling pipe 7 to ensure that the water temperature is maintained at a low temperature so that the ammonia gas can dissolve quickly in water.
[0026] Combined with attachment Figure 2 A spray plate 8 is connected to the upper wall of the treatment box 1, and a number of evenly distributed spray heads 14 are provided below the spray plate 8. The evenly distributed spray heads 14 can ensure that water is fully in contact with ammonia during the spraying process, thereby improving the efficiency and uniformity of ammonia dissolving in water.
[0027] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 4A water inlet pipe 9 connected to the spray plate 8 is connected to the top of the treatment box 1. A water pump 10 is connected to the water inlet pipe 9. A water outlet pipe 11 is connected to the bottom of the treatment box 1. The water outlet pipe 11 is equipped with an electric control valve 12. An air bag 13 is connected to one side of the treatment box 1. A water level monitor 16 is connected to the inner wall of the treatment box 1, below and near the port of the air inlet pipe 2. A waterproof groove 17 is connected to the inner wall of the treatment box 1, between the port of the air inlet pipe 2 and the water level monitor 16. The water level monitor 16 and the waterproof groove 17 can monitor the water level, facilitate timely control of water inflow, and effectively prevent water from entering the air inlet pipe 2 and causing contamination.
[0028] Specific implementation methods of the present utility model: the device is fixed in a suitable position, the end of the air inlet pipe 2 is connected to the external ammonia discharge device, the cooling pipe 7 is connected to the external refrigeration equipment, the water inlet pipe 9 is connected to the external water supply equipment, the device is connected to the external power supply, the electric control valve 3 is opened, and ammonia is introduced into the treatment box 1 through the air inlet pipe 2, and the water pump 10 is turned on at the same time, and water is added into the treatment box 1 through the water inlet pipe 9. The water is sprayed out through the spray head 14, and the water is mixed with the ammonia during the falling process. The reduction motor 6 is turned on, and the reduction motor 6 drives the stirring shaft 4 to rotate, and the stirring shaft 4 drives the stirring blade 5 to rotate. As the water level rises, the stirring blade 5 continuously stirs the water to promote the uniform dissolution of ammonia in water. At the same time, the external refrigeration equipment is turned on to make the coolant flow through the cooling pipe 7 to cool the water to prevent the water temperature from being too high and affecting the dissolution of ammonia in water. At the same time, the temperature monitoring The device 15 detects the water temperature. If the water temperature continues to rise, the refrigeration equipment is controlled to improve the refrigeration efficiency. The water level monitor 16 can also monitor the water level. When the water level is flush with the water level monitor 16, an alarm is sounded. At this time, the electric control valve 13 and the water pump 10 are closed, and the introduction of ammonia and water is stopped. The electric control valve 2 12 is opened to discharge the ammonia water from the outlet pipe 11. When the ammonia in the water is saturated, the ammonia cannot be dissolved in water and will enter the air bag 13. The water saturation can be judged by the swelling of the air bag 13. At this time, the electric control valve 13 and the water pump 10 are also closed, and the electric control valve 2 12 is opened to discharge the ammonia water. During the process, as the cooling pipe 7 continues to work, the water temperature drops, and the ammonia temporarily stored in the air bag 13 and the air inlet pipe 2 can continue to enter the water for dissolution, ensuring full utilization of the water. After the ammonia water is discharged, the electric control valve 2 12 is closed, the electric control valve 13 and the water pump 10 are opened, and the ammonia treatment is carried out again.
