Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a condensation device for waste gas treatment. Background Technology

[0002] Industrial emissions often have harmful effects on the environment and human health. Before being released into the atmosphere, they must be treated to meet emission standards; this process is called waste gas purification and treatment (hereinafter referred to as waste gas treatment). Common waste gas treatment methods include absorption, adsorption, condensation, catalytic conversion, and combustion.

[0003] The condenser is the core equipment in the condensation treatment method. It uses metal plates to efficiently transfer heat to achieve the condensation and recovery of certain substances (volatile organic compounds, etc.) in the waste gas. When the condenser is used to treat heavily polluted or viscous waste gas, scale easily forms on the outer wall of the heat exchanger, requiring timely cleaning to ensure the performance and efficiency of the heat exchanger. Therefore, those skilled in the art continue to strive to find condenser devices that are easy to clean and maintain. Utility Model Content

[0034] Furthermore, the terms "first" and "second" are used only to distinguish between different terms in description and do not have any special meaning.

[0035] Combination Figure 1 and Figure 2As shown, the condensation device for waste gas treatment in this embodiment mainly includes: a main shell 1, N first heat exchangers 2, N second heat exchangers 3, and a cold source pipeline 4, where N is a natural number greater than or equal to 1. A partition (not shown) is provided in the inner cavity of the main shell 1, which divides the inner cavity of the main shell 1 into an inlet channel and an outlet channel, which are connected to the bottom of the partition. The main shell 1 is provided with an inlet 11 and an outlet 12. The inlet 11 connects the inlet channel to the outside to allow the gas to be purified to enter, and the outlet 12 connects the outlet channel to the outside to allow the purified gas to exit. The N first heat exchangers 2 and N second heat exchangers 3 are detachably connected to the main shell 1, with the first heat exchangers 2 located in the outlet channel and the second heat exchangers 3 located in the inlet channel. Each first heat exchanger 2 includes a first liquid inlet 211 and a first liquid outlet 212, and each second heat exchanger 3 includes a second liquid inlet 31 and a second liquid outlet 32. A cold source pipeline 4 is used to connect the first heat exchanger 2 to a cold source, and also to connect the second heat exchanger 3 to a cold source, for the transmission of cold source energy. The cold source can be cooling water or other sources.

[0036] Using the above scheme, the heat exchange components of this device consist of N independently set first heat exchangers 2 and N independently set second heat exchangers 3. When it is necessary to clean and maintain one of the heat exchangers, it can be disassembled individually without affecting the normal operation of other heat exchangers, thus improving the convenience of cleaning and maintaining the condensing device.

[0037] Preferably, both the air inlet 11 and the air outlet 12 are located at the top of the main body shell 1.

[0038] Combination Figures 3 to 5 As shown, the first heat exchanger 2 includes a shell and an S-shaped flow channel disposed within the shell. The first liquid inlet 211 and the second liquid outlet 32 ​​are disposed on the shell and are respectively connected to the beginning and end of the S-shaped flow channel.

[0039] Specifically, the shell of the first heat exchanger 2 is rectangular, and it includes a front plate 21 and a rear plate 22 disposed opposite to each other. (See relevant references.) Figure 5 As shown, the S-shaped flow channel includes multiple transverse plates 23, which are arranged at intervals from top to bottom. Odd-numbered transverse plates 23 (e.g., the 1st, 3rd, 5th, 7th...) have one end connected to the front plate 21 of the casing, while the other end is spaced from the rear plate 22; in other words, there is a gap between the other end and the rear plate 22. Even-numbered transverse plates 23 (e.g., the 2nd, 4th, 6th, 8th...) have one end connected to the rear plate 22 of the casing, while the other end is spaced from the front plate 21 (or, in other words, there is a gap between them). This arrangement of the multiple transverse plates 23 allows the cold source to flow in an S-shape, increasing the heat exchange time and improving heat exchange efficiency by enlarging the cold source flow path.

[0040] like Figure 4 and Figure 5 As shown, the shell of the first heat exchanger 2 also includes a top plate 24 and a bottom plate 25 disposed opposite to each other. A first liquid inlet 211 and a first liquid outlet 212 are both disposed on the front plate 21. The first liquid inlet 211 is located between the top plate 24 and the uppermost horizontal plate 23, and the first liquid outlet 212 is located between the bottom plate 25 and the lowermost horizontal plate 23. That is to say, the cold source flows in from the top of the first heat exchanger 2 and flows out from its bottom.

[0041] like Figure 2 As shown, the main body shell 1 has multiple windows 13, and each first heat exchanger 2 penetrates into the inner cavity of the main body shell 1 through one window 13. Preferably, the front plate 21 of the shell of the first heat exchanger 2 is larger than the window 13 so that the window 13 can be blocked to prevent gas in the intake channel from escaping. The front plate 21 of the first heat exchanger 2 is connected to the main body shell 1 by bolts or other fasteners. When a first heat exchanger 2 is disassembled, a sealing plate (not shown) can be used to block the corresponding window 13 to prevent gas in the intake channel from escaping and ensure that the condenser can work normally.

[0042] Preferably, a handle may also be provided on the front plate 21 of the first heat exchanger 2 to facilitate the installation and removal of the first heat exchanger 2 by personnel.

[0043] Using the above scheme, the first heat exchanger 2 is installed on the main body shell 1 like a drawer, making it easy to assemble and disassemble.

[0044] The shell of the first heat exchanger 2 also includes two side plates arranged opposite each other. Angle steel 26 can be connected to the outer wall of each side plate, and the angle steel 26 is arranged vertically. With this design, the angle steel 26 can strengthen the shell as a whole and guide the gas flow.

[0045] The structure and installation method of the second heat exchanger 3 are roughly the same as those of the first heat exchanger 2. The difference is that the second liquid inlet 31 is located below the second heat exchanger 3, while the second liquid outlet 32 ​​is located above the second heat exchanger 3. That is to say, for the second heat exchanger 3, the second liquid inlet 31 is located between the bottom plate 25 and the lowest horizontal plate 23, and the second liquid outlet 32 ​​is located between the top plate 24 and the highest horizontal plate 23.

[0046] like Figure 1As shown, the cold source pipeline 4 may specifically include N first branch pipes 41, N second branch pipes 42, and N third branch pipes 43, where N is a natural number greater than or equal to 1. The first inlet 211 of each first heat exchanger 2 is connected to the cold source through a first branch pipe 41, and the second outlet 32 ​​of each second heat exchanger 3 is connected to the cold source through a third branch pipe 43. The first outlet 212 of a first heat exchanger 2 is connected to the second inlet 31 of a second heat exchanger 3 through a second branch pipe 42. Thus, the cold source enters the first heat exchanger 2 through the first branch pipe 41, then enters the second heat exchanger 3 through the second branch pipe 42, and finally flows out through the third branch pipe 43 in a cycle.

[0047] Preferably, a valve (not shown) is provided on each first branch pipe 41. In this way, when it is necessary to disassemble a heat exchanger, simply closing the valve on the corresponding first branch pipe 41 will cut off the flow of cold source in the corresponding heat exchanger.

[0048] like Figure 1 As shown, the condensation device in this embodiment also includes a water receiving tray 6 disposed at the bottom of the main body shell 1, which is used to receive waste liquid.

[0049] The condensation device in this embodiment also includes a fan 5 located at the air outlet 12 of the main body shell 1. The fan 5 can force the gas in the air outlet channel to be extracted, thereby increasing the airflow speed.

[0050] In summary, the fluid flow inside the condenser in this embodiment is as follows: high-temperature gas enters the intake channel from the intake port 11 of the main body shell 1 and completes a heat exchange with the cold source in the second heat exchanger 3 in the intake channel. Then, the gas flows from the bottom of the intake channel to the outlet channel and completes a second heat exchange with the first heat exchanger 2 in the outlet channel before flowing out from the outlet port 12. The cold source flows through the cold source pipeline 4 in sequence through the first heat exchanger 2 and the second heat exchanger 3 before flowing out.

[0051] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
