Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of catalytic combustion, in particular to a molecular sieve adsorption box. Background Art
[0002] Ventilation ducts are metal or composite pipes used in ventilation and air-conditioning projects in industrial and civil buildings. They are a kind of municipal infrastructure for air circulation and reducing the concentration of harmful gases. Usually, ventilation ducts are connected to fans. The main reason for adsorption is a "surface force" generated by the molecular gravity acting on the solid surface. When the fluid flows through, some molecules in the fluid collide with the adsorbent surface due to irregular motion, resulting in molecular concentration on the surface, which reduces the number of such molecules in the fluid and achieves the purpose of separation and removal.
[0003] In the existing related technical solutions, during the actual use of the ventilation duct, a large amount of dust and dirt will remain inside the ventilation duct after a long period of work, and some of the dust will fly out from the inside of the ventilation duct, causing damage to the human respiratory tract and easily affecting human health. In addition, since a large amount of dust is blown into the air, it is not conducive to environmental protection. Catalytic combustion equipment often uses honeycomb activated carbon blocks as adsorption and desorption agents, but its regeneration and recycling cycle is only about 50 times, about 1-2 years. Molecular sieves are often used in zeolite wheels, with an unlimited recycling cycle and a lifespan of more than 5 years. Therefore, a molecular sieve adsorption box is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-3 The molecular sieve adsorption box in this embodiment includes a box body 1, a baffle 2 is arranged inside the box body 1, four jacks 3 are opened on the top of the baffle 2, four slide slots 4 are opened on the front and rear sides of the box body 1, a molecular sieve 5 is arranged inside the slide slot 4, a top plate 6 is fixedly installed on the top of the molecular sieve 5, a handle 7 is fixedly installed on the top of the top plate 6, a replacement structure 8 is arranged on the top of the box body 1, a through hole 9 is opened inside the baffle 2, an air inlet pipe 10 is fixedly connected to the left side of the box body 1, and an air outlet pipe 11 is fixedly connected to the right side of the box body 1 The replacement structure 8 includes a fixed seat 801, a rotating rod 802, a movable plate 803, a moving rod 804, a fixed bin 805 and a spring 806. Four fixed seats 801 are fixedly installed on the top of the box body 1, a rotating rod 802 is arranged inside the fixed seat 801, and a movable plate 803 is fixedly installed on the outer surface of the rotating rod 802. Moving rods 804 are arranged on the opposite sides of the two groups of movable plates 803. Four fixed bins 805 are fixedly installed on the inner top wall of the box body 1, and a spring 806 is fixedly installed inside the fixed bin 805.
[0024] like Figure 1 and Figure 2 As shown, the two groups of movable plates 803 are arranged to be symmetrical on the left and right, and the bottoms of the two groups of movable plates 803 are in contact with the tops of the four top plates 6. When the movable plates 803 are in contact with the top plates 6, the spring 806 applies force to the moving rod 804, so that the molecular sieve 5 can be fixed in the slide groove 4.
[0025] like Figure 1 and Figure 3 As shown, the bottoms of the four moving rods 804 penetrate the four movable plates 803 and extend to the bottom of the four movable plates 803. The connections between the four moving rods 804 and the four movable plates 803 are all set to be fixed connections. When the moving rods 804 move downward, they drive the movable plates 803 to rotate around the rotating rod 802.
[0026] like Figure 1 and Figure 3 As shown, the bottom ends of the four moving rods 804 pass through the box body 1 and extend to the inside of the four fixed compartments 805. The bottoms of the four moving rods 804 are fixedly connected to the tops of the four springs 806. The springs 806 provide an upward force to the moving rods 804 so that the movable plate 803 will not move away from the top plate 6.
[0027] like Figure 1 and Figure 2 As shown, the baffle 2 divides the space of the box body 1 into an adsorption zone and an air intake zone from top to bottom. The right end of the air intake pipe 10 penetrates the box body 1 and extends to the air intake zone. When the smoke passes through the through hole 9 to reach the adsorption zone, the molecular sieve 5 adsorbs the smoke in the adsorption zone.
[0028] like Figure 1 and Figure 2 As shown, the left end of the air outlet pipe 11 passes through the box 1 and extends to the inside of the adsorption area. The bottoms of the four molecular sieves 5 are fixedly installed with plugs, and the sizes of the four plugs and the four holes 3 are all adapted to allow the molecular sieves 5 to work stably inside the box 1.
[0029] When implementing, follow these steps:
[0030] 1) First, connect the pipe to the air inlet pipe 10 to allow the combustion smoke to enter the box 1;
[0031] 2) The smoke then passes through the through hole 9 and enters the adsorption area, where the four molecular sieves 5 adsorb the smoke simultaneously;
[0032] 3) When the molecular sieve 5 reaches the end of its service life, the moving rod 804 is pressed to tilt the movable plate 803;
[0033] 4) Finally, the old molecular sieve 5 is taken out from the chute 4 and replaced with a new molecular sieve 5 .
[0034] In summary, the molecular sieve adsorption box is provided with a replacement structure 8. When the molecular sieve 5 reaches its service life, it is necessary to replace the molecular sieve 5. The moving rod 804 is pressed to rotate the movable plate 803 around the rotating rod 802. The moving rod 804 presses the spring 806 downward, and the spring 806 is compressed to make the bottom plate of the movable plate 803 away from the top plate 6. Then, the handle 7 is held to lift the molecular sieve 5 and replace it with a new molecular sieve 5. Then, the moving rod 804 is released, the spring 806 rebounds, and the movable plate 803 fixes the top plate 6, thereby completing the replacement function of the molecular sieve 5. The molecular sieve adsorption box is provided with a through hole 9. When the catalytic combustion equipment needs to be adsorbed, the pipeline is connected to the air inlet pipe 10 to allow the combustion smoke to enter the inside of the box body 1 and reach the air inlet area. Then, the smoke passes through the through hole 9 and enters the adsorption area. The four molecular sieves 5 adsorb the smoke at the same time, and then the clean air that has been adsorbed flows out of the box body 1 from the air outlet pipe 11, thereby completing the adsorption function of the catalytic combustion equipment.
