Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an activated carbon treatment box for air purification in a heat treatment workshop. Background Technology

[0002] In industrial production processes, especially in heat treatment workshops, large amounts of smoke, harmful gases, and particulate matter are often generated. These pollutants not only endanger the health of operators but can also have long-term adverse effects on the surrounding environment. Heat treatment workshops typically employ a series of purification measures, among which spraying is a commonly used pretreatment method. Spraying can remove some smoke and particulate matter, but residual harmful gases and particles still require further purification in an activated carbon treatment box before being discharged at high altitude. In existing activated carbon treatment boxes, the gas to be treated enters from the side, flows laterally without changing direction, and is directly treated by the activated carbon layer before being discharged through the outlet. Firstly, increasing the airflow area requires vertically increasing the height, which hinders later maintenance and other operations. Secondly, it leads to uneven utilization of some activated carbon layers. Finally, replacing activated carbon requires shutting down the activated carbon treatment box, which results in significant economic losses in heat treatment workshops requiring continuous production. Utility Model Content

[0003] This invention provides an activated carbon treatment box for air purification in a heat treatment workshop, which solves the technical problems of low purification efficiency and inconvenience for continuous operation of activated carbon treatment layers in the prior art.

[0004] To solve the above problems, the activated carbon treatment box for air purification in heat treatment workshops provided by this utility model adopts the following technical solution:

[0005] The device includes a housing containing activated carbon. One end of the housing has an air inlet, and the other end has an air outlet. The housing is divided into an upper purification chamber and a lower purification chamber by a horizontal partition. Both the upper and lower purification chambers have removable drawers for holding the activated carbon. An air guide channel is formed within the partition, with one end open and opposite the air inlet. Both the upper and lower plates of the air guide channel have equalization holes. An inclined guide plate is located at the end of the partition near the air inlet, and a deflection limiting plate is located at the end of the partition near the air outlet.

[0006] Furthermore, both the upper and lower purification chambers are equipped with support plates for supporting the drawer structure. The support plates are arranged in a plurality of spaced-apart configurations. The front of the box body is provided with a groove, and the bottom edge of the groove is on the same horizontal plane as the upper surface of the support plate.

[0007] Furthermore, the support plates on both sides abut against the adjacent structures.

[0008] Furthermore, a flow channel is formed between the upper end face of the redirecting limiting plate and the top plate of the upper purification chamber, and a flow channel is formed between the lower end face of the redirecting limiting plate and the bottom plate of the lower purification chamber.

[0009] Furthermore, the flow channel is provided with a detachable U-shaped baffle, and the box body is provided with an installation groove corresponding to the U-shaped baffle.

[0010] Furthermore, one end of the U-shaped baffle is provided with a sealing baffle that covers the mounting groove.

[0011] Furthermore, the mounting groove is provided with a removable sealing plate.

[0012] Furthermore, a buffer cavity is formed on the side of the redirection limiting plate that is close to the air outlet.

[0013] The beneficial effects of the activated carbon treatment box for air purification in a heat treatment workshop provided by this utility model are:

[0014] In this invention, the housing is divided into upper and lower purification chambers by a partition. Air flows through the air guide channels and equalization holes to form a T-shaped three-dimensional flow, increasing the surface area of ​​the activated carbon facing the wind and allowing for more thorough contact between the air and the activated carbon, thus significantly improving purification efficiency. The air guide channels and equalization holes work together to slow down the airflow and prolong the residence time of the air in the chamber, ensuring that pollutants (such as VOCs and odors) are fully adsorbed by the activated carbon, resulting in a more thorough purification effect.

[0015] In this invention, by setting a deflection limiting plate and a buffer chamber, the air is purified and then flows into the air outlet through the flow channel. The buffer chamber design further balances the airflow pressure and reduces wind resistance and noise.

[0016] This utility model features a U-shaped baffle switching function: when replacing activated carbon, installing the U-shaped baffle can temporarily close the upper or lower chamber flow channel, allowing airflow to pass through a single chamber, while the activated carbon in the other chamber can be replaced offline, achieving non-stop maintenance, suitable for scenarios requiring continuous operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0025] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0026] An embodiment of the activated carbon treatment box for air purification in a heat treatment workshop provided by this utility model:

[0027] like Figures 1 to 3 As shown,

[0028] The device includes a housing 1, which contains activated carbon. One end of the housing 1 has an air inlet 11, and the other end has an air outlet 12. In actual use, the air to be purified enters through the air inlet 11, is treated by the activated carbon, and is then discharged through the air outlet 12.

[0029] In this embodiment, the housing 1 is divided into an upper purification chamber 13 and a lower purification chamber 14 by a horizontal partition 2. Activated carbon is placed in both the upper purification chamber 13 and the lower purification chamber 14. An air guide channel 21 is formed in the partition 2. One end of the air guide channel 21 is open and faces the air inlet 11. The upper plate and the lower plate of the air guide channel 21 are provided with flow equalization holes 22.

[0030] The air to be treated enters through the air inlet 11 and then enters the air guide trough 21, followed by corresponding flow equalization holes 22 into the upper purification chamber 13 and the lower purification chamber 14. This increases the surface area of ​​the activated carbon exposed to the wind, improving the purification effect and efficiency. Furthermore, the combined effect of the horizontal air guide trough 21 and the vertical flow equalization holes 22 forms a T-shaped three-dimensional flow distribution system, which slows down the airflow and enhances the purification effect.

[0031] In this embodiment, both the upper purification chamber 13 and the lower purification chamber 14 are equipped with detachable drawer structures 3 for holding activated carbon. It should be noted that the bottom surface of the drawer structure 3 is a porous mesh structure, which facilitates vertical ventilation.

[0032] Specifically, both the upper purification chamber 13 and the lower purification chamber 14 are provided with support plates 131 for supporting the drawer structure 3. The support plates 131 are arranged in several spaced intervals. The front of the box body 1 is provided with a slot 15, and the bottom edge of the slot 15 is on the same horizontal plane as the upper surface of the support plate 131.

[0033] In use, the drawer structure 3 can be disassembled and installed through the slot 15, facilitating the replacement of the activated carbon inside. The outer end face of the drawer structure 3 is provided with a baffle plate covering the slot 15, and the baffle plate is detachably connected to the side of the box body 1 by bolts.

[0034] After the baffle plate of drawer structure 3 is fixedly installed, the rear end face of drawer structure 3 abuts against the rear end face of upper purification chamber 13 or lower purification chamber 14.

[0035] In this embodiment, a sloping guide plate 4 is provided at the end of the partition 2 that is close to the air inlet 11. Two symmetrically arranged sloping guide plates 4 are used. The sloping guide plates 4 allow the air to be processed to enter the air guide trough 21.

[0036] In this embodiment, the support plates 131 on both sides abut against the adjacent structures.

[0037] A deflector plate 5 is provided at the end of the partition 2 that is close to the air outlet 12. A buffer cavity 17 is formed on the side of the deflector plate 5 that is close to the air outlet 12.

[0038] Specifically, the side of the support plate 131 on the left abuts against the side of the corresponding redirecting and limiting plate 5; the support plate 131 on the right in the upper purification chamber 13 abuts against the corresponding inclined guide plate 4; and the support plate 131 on the right in the lower purification chamber 14 abuts against the side wall of the lower purification chamber 14. The main purpose is to form a closed structure on the outer side of the support plate 131 on the side, preventing air entering the upper purification chamber 13 or the lower purification chamber 14 from being directly discharged without being treated by activated carbon.

[0039] In this embodiment, a flow channel 51 is formed between the upper end face of the redirection limiting plate 5 and the top plate of the upper purification chamber 13, and a flow channel 51 is formed between the lower end face of the redirection limiting plate 5 and the bottom plate of the lower purification chamber 14.

[0040] The flow channel 51 is equipped with a detachable U-shaped baffle 52. The housing 1 is provided with a mounting groove 16 corresponding to the U-shaped baffle 52, and one end of the U-shaped baffle 52 is provided with a sealing baffle 521 covering the mounting groove 16. The sealing baffle 521 is detachably fixed to the side of the housing 1 by bolts.

[0041] A removable sealing plate 161 can also be installed at the mounting slot 16.

[0042] In normal use, the U-shaped baffle 52 is not installed, and the sealing plate 161 is installed in the mounting groove 16 with bolts, ensuring a seal at the mounting groove 16. At this time, the flow channel 51 is in a free-flowing state and can be used normally.

[0043] When activated carbon needs to be replaced, the activated carbon in the upper purification chamber 13 can be replaced first. At this time, the U-shaped baffle 52 at the upper end of the deflection limiting plate 5 is installed. After the U-shaped baffle 52 is installed, its upper surface is in close contact with the lower surface of the top plate of the upper purification chamber 13, thus blocking the flow channel 51 at the upper end of the deflection limiting plate 5. The air to be treated will then pass through the activated carbon in the lower purification chamber 14 for treatment, thus ensuring that the activated carbon can be replaced without stopping the operation. The same method can be used to replace the activated carbon in the lower purification chamber 14.

[0044] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0045] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
