Description

Technical Field

[0001] This utility model relates to the technical field of ammonia-air mixer equipment, and in particular to a high-efficiency and energy-saving ammonia-air mixer based on urea hydrolysis for ammonia production. Background Technology

[0002] The working principle of the ammonia-air mixer is mainly based on the Venturi effect, which achieves uniform mixing of ammonia and air through a specific structural design.

[0003] Specifically, low-pressure air enters through the air inlet of the ammonia-air mixer, passes through the mixer, and reaches the Venturi mixing tube formed by the pipe narrowing. At this point, relatively high-pressure ammonia gas enters the mixer through the ammonia inlet and is guided to the Venturi nozzle through an internal pipe. The ammonia gas is ejected from the Venturi nozzle; due to the high ejection velocity, a negative pressure zone is formed around it, creating an adsorption effect that draws air into the Venturi mixing tube. Within the diffusion chamber of the Venturi mixer, the ammonia and air are uniformly mixed according to a set ratio, and finally delivered to the point of use.

[0004] Existing ammonia-air mixers require a large amount of electrical equipment for auxiliary operation, which increases the overall cost of use and installation. They also have the drawback of not being able to effectively solve the problem of uneven mixing of ammonia and air, causing many inconveniences and affecting normal operation.

[0005] Therefore, this utility model provides a high-efficiency and energy-saving ammonia-air mixer based on urea hydrolysis for ammonia production. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency and energy-saving ammonia-air mixer based on urea hydrolysis for ammonia production.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency and energy-saving ammonia-air mixer based on urea hydrolysis for ammonia production, comprising a mixer cylinder,

[0008] A dilution air inlet is installed at one end of the mixer cylinder, and an ammonia inlet pipe is installed at the top of the mixer cylinder. An ammonia inlet is installed at the top of the ammonia inlet pipe. The ammonia inlet is used to guide ammonia into the interior of the mixer cylinder, and the dilution air inlet is used to guide air into the interior of the mixer cylinder.

[0009] The dilution air inlet has a central cylinder installed inside, and a spiral blade is installed on the outside of the central cylinder. The central cylinder and the spiral blade are used to mix ammonia and air.

[0010] A nozzle is installed on one side of the central cylinder, and an elbow is installed at one end of the nozzle. The top end of the elbow is connected to the bottom of the ammonia inlet pipe. A blocking plate is installed on the outside of the nozzle, and the blocking plate is located on the side of the nozzle away from the elbow. The elbow is used to assist in the introduction of gas into the interior, and the nozzle is used to assist in the delivery of gas to one side of the spiral blades for subsequent mixing.

[0011] In a preferred embodiment, the dilution air inlet includes a first sealing flange and first positioning bolts. The first sealing flange is installed at one end of the mixer cylinder. A first air inlet cavity is formed in the middle of the first sealing flange. Multiple equidistant first positioning bolts are threaded onto the outer side of the first sealing flange, and these bolts are arranged in a ring around the first air inlet cavity to facilitate connection between multiple mixer cylinders. The ammonia inlet includes a second sealing flange and second positioning bolts. A second sealing flange is installed at the top end of the ammonia inlet pipe. A second air inlet cavity is formed in the middle of the second sealing flange. Multiple equidistant second positioning bolts are threaded onto the outer side of the second sealing flange, and these bolts are arranged in a ring around the second air inlet cavity. By using a second sealing flange and a second air inlet cavity at the top of the ammonia inlet pipe for positioning and installation when connecting to other pipes, the flexibility of equipment use is improved.

[0012] The technical effect of adopting the above-mentioned further solution is that multiple first positioning bolts are distributed in a circular shape at equal intervals around the first air inlet cavity, which helps to connect multiple mixer cylinders.

[0013] In a preferred embodiment, a mixer outlet is installed at the end of the mixer cylinder away from the dilution air inlet. The mixer outlet has a first sealing flange and a first positioning bolt with the same structure inside, thereby limiting the two sides of the mixer cylinder when it is used as a whole, which facilitates the subsequent installation and connection of multiple devices at both ends. The dilution air inlet has a cylindrical structure, which is practical, simple, easy to process, and convenient to install.

[0014] The technical effect of adopting the above-mentioned further solution is that when the mixer cylinder is used as a whole, the two sides are limited, which facilitates the subsequent installation and connection of multiple devices at both ends.

[0015] In a preferred embodiment, the spiral blades are spiral-shaped and there are three sets of spiral blades. By welding three sets of spiral blades onto the central cylinder and placing them at a certain angle, the mixing time of ammonia and air is increased, allowing the air and ammonia to mix fully and thus improving the mixing efficiency.

[0016] The technical effect of adopting the above-mentioned further scheme is that the three sets of spiral blades are at a certain angle, which increases the mixing time of ammonia and air, allowing air and ammonia to mix fully, thereby improving the mixing efficiency.

[0017] In a preferred embodiment, the outer side of the ammonia inlet pipe is provided with equally spaced oblique holes, the diameter of which is 15mm and the radial angle of which is 60°. The overall structure does not use electrical equipment for operation, thus saving overall installation and usage costs.

[0018] The technical advantage of adopting the above-mentioned further solution is that the overall structure does not use electrical equipment for auxiliary operation, thus saving the overall installation and use costs.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. This utility model is simple to use, easy to process, and convenient to install, by using a dilution air inlet, a mixer cylinder and an ammonia inlet together;

[0021] 2. This utility model, by setting up a spiral blade and a central cylinder, constitutes a complete swirling device. By utilizing the rotating flow field, the mixing time of ammonia and air is increased, allowing air and ammonia to be fully mixed, thereby improving the mixing efficiency.

[0022] 3. The swirling device of this utility model can quickly achieve uniform mixing in a very short distance, eliminating uneven stratification. The second positioning bolts are distributed in a circular shape at equal intervals around the second air inlet cavity. The positioning installation is carried out by using a second sealing flange at the top of the ammonia inlet pipe and the second air inlet cavity to connect with other pipes, which improves the flexibility of the equipment during use. The first positioning bolts are distributed in a circular shape at equal intervals around the first air inlet cavity to assist in the connection of multiple mixer cylinders. The overall structure does not use electrical equipment to assist in operation, saving the overall installation and use costs. Attached Figure Description
