Description

Technical Field

[0001] The utility model relates to the technical field of environmental flue gas analysis, in particular to a purification material placement device for a laboratory. Background Art

[0002] Ambient flue gas has a complex composition, requiring a combination of different purification materials to achieve optimal purification results. In practice, different purification materials are typically stacked layer by layer to form a filter. To develop purification materials with improved performance, laboratory simulations and evaluations are necessary. However, there is currently a lack of equipment capable of simulating the placement of purification materials in actual application environments.

[0003] Existing mature methods, such as the invention patent with publication number CN116947151A, the invention name of which is: an internal purification treatment system for experimental equipment, use a grid method for stacking, and its essence is to make the filter material itself into a mesh shape; for example, the utility model patent with publication number CN219072554U, the invention name of which is: a cell laboratory air purification and drying device, and the utility model patent with publication number CN218516339U, a laboratory biological safety cabinet air inlet grille, both use this method for stacking, which is commonly used.

[0004] However, in the experimental verification phase, making the purification material into the above-mentioned shape requires a lot of process and is too difficult, which is not conducive to improving the experimental efficiency; and the method of directly stacking the purification materials similar to the water purification method is not conducive to subsequent separation and analysis.

[0005] In short, there is an urgent need to design a purification material placement device that can be used for flue gas purification analysis to solve the problem of evaluating different purification materials in flue gas purification analysis.

[0006] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0035] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0036] Example 1

[0037] like Figures 1-4 As shown, a laboratory purification material placement device includes a basic component 1 and a stackable component 2.

[0038] In this embodiment, the basic component 1 includes a main body 11, a first connecting part 12 arranged at the upper end of the main body 11, and a second connecting part 13 arranged at the lower end of the main body 11. The overall shape of the basic component 1 is a cross, the diameter of the main body 11 is larger, and the diameter of the first connecting part 12 is smaller. The main body 11, the first connecting part 12 and the second connecting part 13 are internally provided with a first air flow channel running axially therethrough, and a first screen 14 is installed in the first air flow channel.

[0039] The stackable component 2 includes a lower connecting portion 21 and an upper connecting portion 22, wherein the lower connecting portion 21 is used to adapt to the first connecting portion 12 of the base component 1 or the upper connecting portion 22 of other stackable components 2 to achieve connection, and the upper connecting portion 22 is used to adapt to the lower connecting portion 21 of other stackable components 2 to achieve connection, and a second air flow channel axially penetrating therethrough is provided inside the stackable component 2, and a second screen 23 is provided in the second air flow channel, wherein the stackable component 2 is generally in an inverted T shape, and the diameter of the lower connecting portion 21 is larger than the diameter of the upper connecting portion 22.

[0040] The second connection portion 13 of the base component 1 and the upper connection portion 22 of the stackable component 2 are also used for external connection, such as connection with an interface of experimental equipment.

[0041] The purification material placement space is formed between the first screen 14 and the adjacent second screen 23, and between two adjacent second screens 23, for storing the purification material. Figure 2 The middle represents the inner area between the positions 5 where the screen is located.

[0042] The pore size of the screen is 10-200 meshes, which can prevent most of the purification materials from passing through, but can ensure the passage of airflow.

[0043] In this embodiment, the first connecting portion 12, the upper connecting portion 22 and the lower connecting portion 21 are matched threaded connection structures, and the second connecting portion 13 is a threaded connection structure. When stacking, the connection and locking are achieved by threaded connection. To ensure sealing, a sealing ring 3 is provided at the connection between the main body 11 and the first connecting portion 12 of the basic component 1 and at the connection between the lower connecting portion 21 and the upper connecting portion 22 of the stackable component 2.

[0044] In other embodiments, the first connection portion, the upper connection portion and the lower connection portion are matched socket connection structures or lock connection structures. The second connection portion is also a socket connection structure or a lock connection structure.

[0045] By matching components, different connection forms are formed, which require sealing and connection stability.

[0046] In this embodiment, the base component 1 and the stackable component 2 are both made of stainless steel, and both the base component and the stackable component are of an integrated structure.

[0047] In other embodiments, the material may be other heat-conducting materials, and the structure may be designed as a split structure.

[0048] Working principle description:

When in use, the purification material is placed in the purification material placement space by opening the basic component 1 and the stackable component 2, and then re-tightened. The second connection part 13 of the basic component 1 and the upper connection part 22 of the stackable component 2 are then connected to the air path of the equipment to allow the flue gas to pass through. The components of the purified flue gas and the intercepted components are then analyzed respectively to make a simulated evaluation of the purification material.

[0050] Example 2

[0051] like Figure 5 As shown, in this embodiment, the number of the stackable components 2 is designed to be two, and the two stackable components 2 are stacked one by one on the base component 1.

[0052] In other embodiments, more stackable components can be stacked.

[0053] In this embodiment and other embodiments, the number of stackable components 2 can be increased to increase the space for placing purification materials, so that different purification materials can be placed in different combinations. After connecting them in a set manner, they are connected to the air path of the equipment to simulate and evaluate the purification effect of the flue gas.

[0054] Example 3

[0055] To ensure uniform specifications of the purification material placement space, the first screen 14 is located in the transition area between the main body 11 and the first connecting part 12 of the base component, and the second screen 23 is located in the transition area between the lower connecting part 21 and the upper connecting part 22.

The heating module 4 is mounted on the outside of the assembled basic components and stackable components. The heating area of ​​the heating module at least covers all the purification material placement spaces.

[0058] The heating module 4 may be a heating sleeve with a built-in resistance wire or thermocouple to achieve heating and temperature control by electric heating.
