Description

Technical Field

[0001] The invention relates to a zeolite wheel purification device, in particular to a conical high-efficiency zeolite wheel adsorption concentration purification device, belonging to the field of VOCs treatment technology and storage dehumidification and drying technology. Background Art

[0002] Among the existing organic gas treatment or dehumidification system equipment, the zeolite rotor is the most advanced treatment equipment. Traditional zeolite rotors are usually designed and manufactured as a whole, so they need to be installed and transported as a whole. The entire installation and transportation are difficult, and the zeolite module is difficult to replace, and the production and subsequent maintenance costs are high. For its specific structural design, the rotor air inlet is usually a mutation type, which makes the adsorption efficiency and stability of the overall equipment very low. In addition, when dealing with large air volumes of organic gases, the traditional zeolite rotor is bulky, which affects the spatial layout, and there is a contradiction between large air volume but small actual placement space. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a conical high-efficiency zeolite rotor adsorption concentration purification device with a simple structure, a high gas processing capacity under the same wind speed, a relatively small footprint, and a standardized zeolite module design, thereby making it easy to transport and install and having low production and subsequent maintenance costs.

[0004] In order to solve the above technical problems, the conical high-efficiency zeolite rotor adsorption concentration and purification device of the present invention includes a rotor shell, an adsorption gas inlet is arranged on the front side of the rotor shell, an adsorption gas outlet is arranged on the rear side of the rotor shell, a guide plate close to the adsorption gas inlet is arranged in the rotor shell, a zeolite rotor close to the adsorption gas outlet is arranged in the rotor shell, the VOCs gas entering from the adsorption gas inlet can be evenly dispersed through the guide plate and then discharged from the adsorption gas outlet through the zeolite rotor, a desorption gas inlet is arranged at the adsorption gas outlet, a desorption gas outlet is arranged on the rotor shell facing the zeolite rotor, and the high-temperature gas entering from the desorption gas inlet can desorb organic matter adsorbed on the zeolite rotor and discharge it through the desorption gas outlet.

[0005] A reduction motor is arranged in the rotor housing and is located behind the zeolite rotor. A transmission gear matched with the reduction motor is arranged at the bottom of the zeolite rotor.

[0006] The zeolite rotor comprises a conical zeolite module and a planar zeolite module arranged on the top surface of the conical zeolite module.

[0007] The adsorption gas inlet is a gradually expanding air inlet.

[0008] The matching angles among the tapered surfaces of the gradually diverging air inlet, the guide plate and the zeolite module enable the air intake direction to be perpendicular to the zeolite module.

[0009] The desorption gas inlet and the desorption gas outlet are both provided with a heat preservation layer.

[0010] The desorption gas inlet is vertically arranged at the adsorption gas outlet.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By rationally arranging the gradually expanding inlet and guide plate in the rotor shell, the airflow can be evenly distributed, greatly improving the overall adsorption efficiency and stability. The structural design of the conical zeolite module and the flat zeolite module placed on the top of the conical zeolite module can not only reduce the volume of the entire equipment and effectively reduce the floor space, but also greatly increase the gas processing capacity. At the same time, the modular structural design of the zeolite rotor is convenient for production, transportation and installation. In addition, the adsorption and desorption structure formed reduces the difficulty of processing and assembly, and reduces the cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The conical high-efficiency zeolite rotor adsorption concentration purification device of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] In the description of the present invention, it should be noted that the terms "top", "bottom", "left side", "right side" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] As shown in the figure, the conical high-efficiency zeolite rotor adsorption concentration purification device of the present invention comprises a rotor shell 1, which adopts a sheet metal structure and is integrally sealed without leakage; the front side of the rotor shell 1 ( Figure 1The left side in the middle is defined as the front side) and a gradually expanding adsorption gas inlet 4 is provided. Specifically, the gradually expanding adsorption gas inlet 4 includes a rectangular opening, and the rectangular opening is internally connected to a gradually expanding air inlet plate for dispersing the airflow. The rear side ( Figure 1 The right side in the middle is defined as the rear side) and is provided with an adsorbed gas outlet 5. Of course, it can be seen from the figure that the side of the runner housing 1 close to the gradually expanding adsorbed gas inlet 4 is set as a conical outer contour structure, and the main part of the runner housing 1 is set as a cylindrical structure. A guide plate 8 close to the adsorbed gas inlet is arranged in the runner housing 1, and a zeolite runner close to the adsorbed gas outlet is arranged in the runner housing 1, that is to say, the zeolite runner is arranged in the cylindrical structure, and the guide plate 8 enters the cylindrical structure part from the conical outer contour structure part, and guides the gas flow before the gas enters the planar zeolite module 31 and the conical zeolite module 32. A reduction motor 2 is arranged in the runner housing 1 and is located behind the zeolite runner. A transmission gear matching with the reduction motor 2 is arranged at the bottom of the zeolite module. The wheel is driven by the reduction motor 2 and is connected with gears to achieve uniform rotation; the VOCs gas entering from the adsorption gas inlet 4 can be evenly dispersed through the guide plate 8 and then discharged from the adsorption gas outlet 5 through the zeolite wheel. A desorption gas inlet 6 is arranged on the side wall of the adsorption gas outlet 5. As can be seen from the figure, the desorption gas inlet 6 can be vertically arranged at the adsorption gas outlet, and a desorption gas outlet 7 facing the zeolite module is arranged on the top of the wheel shell 1. The desorption gas outlet 7 can be perpendicular to the air inlet direction. The high-temperature gas entering from the desorption gas inlet 6 can desorb the organic matter adsorbed on the zeolite module and discharge it through the desorption gas outlet 7. The adsorption and desorption structure thus formed has no dedicated cooling partition area, but can still complete the cooling function, thereby reducing the difficulty of processing and assembly and reducing costs.

[0019] Furthermore, the zeolite rotor comprises a conical zeolite module 32 and a planar zeolite module 31 arranged on the top surface of the conical zeolite module 32, wherein the conical zeolite module 32 serves as the main part of the zeolite rotor, and its outer surface forms an outer conical structure, and the planar zeolite module 31 is arranged on the top of the conical zeolite module 32, that is, the planar zeolite module 31 is directly opposite to the gradually expanding adsorption gas inlet 4, thereby greatly increasing the exhaust gas flow area, and increasing the processed air volume under the same wind speed. Of course, the outer conical structure of the zeolite rotor can flexibly adjust the plane size and depth size according to the on-site space conditions to meet the performance and space requirements. In addition, since the zeolite rotor comprises a conical zeolite module 32 and a planar zeolite module 31 arranged on the top surface of the conical zeolite module 32, its modular form can be designed according to actual needs and standardized production, which is convenient for production, transportation and installation.

[0020] Furthermore, the matching angles among the gradually expanding air inlet, the guide plate 8 and the conical surface of the zeolite module can make the air intake direction perpendicular to the zeolite module. Specifically, by matching the angles of the gradually expanding air inlet, the guide plate and the outer conical surface of the zeolite rotor, the air intake direction is perpendicular to the zeolite rotor and parallel to the honeycomb pores, thereby reducing wind resistance.

[0021] Furthermore, the desorption gas inlet 4 and the desorption gas outlet 5 are both provided with a thermal insulation layer, which plays a role of heat insulation and reduces the energy consumption of the system.

[0022] Here’s how it works:

[0023] VOCs gas enters from the adsorption gas inlet 4, is guided by the guide plate 8, and is adsorbed on the planar zeolite module 31 and the conical zeolite module 32. The purified gas is discharged from the adsorption gas outlet 5; high-temperature gas enters from the desorption gas inlet 6, desorbs the organic matter adsorbed on the planar zeolite module 31 and the conical zeolite module 32, and the gas accompanied by high-concentration organic matter is discharged through the desorption gas outlet 7 to enter the next-level equipment for treatment. Driven by the reduction motor 2, the zeolite wheel is always in low-speed operation to realize the alternating conversion of adsorption and desorption.

[0024] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
