Description

Technical Field

[0001] The utility model relates to the technical field of carbonization maintenance equipment, in particular to a multi-bin type carbonization maintenance device. Background Art

[0002] Low-carbon technologies can be divided into three categories according to the implementation stage: source carbon reduction, process carbon reduction, and terminal carbon fixation. Carbon dioxide curing cement-based materials belongs to terminal carbon fixation technology, which mainly utilizes the characteristics of alkaline silicate clinker minerals in cement that generally have carbonation activity. Through carbonization reaction, a structure with carbonate minerals as the skeleton and amorphous silicate as the cementing body is formed, and it has excellent carbon fixation effect and mechanical properties.

[0003] The carbonization reaction of cement-based materials is a relatively intense exothermic process. In large-volume curing devices, concentrated carbonization heat release often causes a sharp rise in temperature inside the curing device, causing the cured products to release a large amount of water vapor, thus affecting the subsequent carbonization reaction process. At the same time, due to the difference in density between carbon dioxide and other gases, large-volume curing devices often have uneven distribution of carbon dioxide concentration, resulting in differences in the final performance of the products.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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.

[0026] Combine the following Figure 1 The utility model describes a multi-chamber carbonization curing device.

[0027] In view of the problems of concentrated carbonization heat release and uneven distribution of carbon dioxide concentration in the carbonization device in the conventional technology, the embodiment of the utility model provides a multi-chamber carbonization curing device, including a plurality of carbonization chambers 1 arranged at intervals and a connecting pipe 4.

[0028] Specifically, each carbonization bin 1 is provided with an air inlet 2 and an air outlet 3, and a connecting pipe 4 is used to connect each carbonization bin 1. The connecting pipe 4 includes a main pipe 5 and a plurality of first branch pipes 6 and a second branch pipe 7 respectively provided on the main pipe 5. The main pipe 5 is provided with a main air inlet 8 and a main air outlet 9, and carbon dioxide gas can be introduced through the main air inlet 8, and waste gas can be released through the main air outlet 9. In order to facilitate the connection of each carbonization bin 1, the adjacent first branch pipe 6 and the second branch pipe 7 are used to communicate with the air inlet 2 and the air outlet 3 of the corresponding carbonization bin 1 respectively. It can be understood that a first branch pipe 6 and a second branch pipe 7 form a group of branch pipes, and a plurality of groups of branch pipes are provided on the main pipe 5, and each group of branch pipes is used to connect a corresponding carbonization bin 1. Further, the first branch pipe 6 and the second branch pipe 7 are respectively provided with a first valve 10 and a second valve 11, and the opening and closing of the corresponding carbonization bin 1 can be controlled by the first valve 10 and the second valve 11. The multi-chamber carbonization curing device provided by the utility model can avoid the phenomenon of concentrated heat release during carbonization by setting up multiple independent carbonization chambers 1 and connecting them through a connecting pipe 4. At the same time, the air supply through the multiple carbonization chambers 1 also solves the impact of uneven distribution of carbon dioxide concentration.

[0029] Since the first branch pipe 6 and the second branch pipe 7 are directly connected to the main pipe 5, in order to make the intake air flow in one direction, a first one-way valve 13 is provided on each first branch pipe 6, and the first one-way valve 13 can ensure that the intake air directly enters the carbonization bin 1 from the first branch pipe 6, but does not flow into the carbonization bin 1 from the first branch pipe 6. It should be noted that after the product is placed in the carbonization bin 1 and the bin body is closed, the first valve 10 and the second valve 11 need to be opened, and the carbon dioxide gas enters each carbonization bin 1 from the main pipe 5 in turn to perform the carbonization maintenance operation.

[0030] There are many ways to set up the main pipeline 5. It can be a strip-shaped pipeline with an air inlet 2 and an air outlet 3 formed at both ends. In other optional embodiments, in order to promote the circulation of gas, the main pipeline 5 is annular, and each carbonization bin 1 is arranged in a ring shape and is connected to the main pipeline 5. In this way, by controlling the opening and closing of the valve, the gas circulates on the main pipeline 5, which improves the carbonization effect while reducing the amount of gas. Furthermore, in the technical solution provided by the utility model, the main air inlet 8 and the main air outlet 9 are arranged adjacent to each other. In order to enable the gas to circulate in one direction, a second one-way valve 14 is provided on the main pipeline 5 on the side of the main air outlet 9 away from the main air inlet 8, so as to prevent the main air outlet 9 from circulating in one direction. Figure 1 Taking the arrangement shown in as an example, the gas circulates in reverse in the main pipeline 5.

[0031] Since multiple carbonization bins 1 are arranged on the main line 5, multiple third valves 12 are also arranged on the main line 5 so that the gas can be recycled after passing through each carbonization bin 1 in sequence. Each third valve 12 is located between two adjacent first valves 10 and second valves 11. When performing carbonization maintenance, each third valve 12 needs to be closed, and the gas circulates into each carbonization bin 1 in sequence from the first valve 10 and the second valve 11, and circulates in the entire multi-bin carbonization maintenance device. Furthermore, in some cases, some carbonization bins 1 may not need to be used. Therefore, for carbonization bins 1 without materials, the first valve 10 and the second valve 11 can be closed, and the third valve 12 can be opened, so that the gas will not enter the empty carbonization bin 1.

[0032] Furthermore, since the weight of carbon dioxide gas is heavier than that of air, in the technical solution provided by the present utility model, the carbonization bin 1 includes a cylinder and a cover, the air inlet 2 is arranged on one side of the cylinder, and the air outlet 3 is arranged on the cover. That is, the height of the air inlet 2 is arranged lower than that of the air outlet 3 to promote the transmission of gas in the bin and prevent carbon dioxide from being deposited at the bottom due to its high density. In an optional embodiment, please refer to Figure 1 The air inlet 2 is arranged on the side wall of the cylinder near the bottom.

[0033] Furthermore, a pressure concentration detector 15 is also provided on the main pipe 5. It should be noted that when the pressure concentration detector 15 detects that the gas concentration in the main pipe 5 is significantly lower than the set value, the main gas outlet 9 of the main pipe 5 needs to be opened to discharge the waste gas. This means that after the carbonization is completed, the main air inlet 8 of the main pipe 5 needs to be closed first, and the main gas outlet 9 needs to be opened to discharge the waste gas. If carbon dioxide-containing flue gas is used for maintenance, an exhaust gas device can be installed at the exhaust end.

[0034] Furthermore, the main pipeline 5 is also provided with a plurality of temperature and humidity controllers 16 for monitoring and regulating the temperature and humidity in each carbonization bin 1. The temperature and humidity detector may be provided with one for each carbonization bin 1, or may be provided with one for multiple carbonization bins 1. In an optional embodiment, at most three adjacent carbonization bins 1 are provided with one temperature and humidity controller 16.

[0035] The following is a brief description of the use process of the device: put the products into multiple independent carbonization bins 1 and close the bin body, open the main air inlet 8 of the main line 5, keep the main air outlet 9 closed, and the carbon dioxide gas enters the main line 5. Due to the presence of the first one-way valve 13 and the second one-way valve 14, the gas circulates counterclockwise. Open the air inlet 2 and air outlet 3 of the independent carbonization bin 1 containing the products, and close the third valve 12 between the air inlet and outlet 3 of the independent carbonization bin 1, so that the air flow continuously passes through multiple independent carbonization bins 1 and forms an internal circulation in the entire device; at this time, the temperature and humidity in the carbonization bin 1 can be monitored and regulated by multiple temperature and humidity controllers 16, and the gas pressure and concentration in the carbonization bin 1 can be monitored by the pressure concentration detector 15. When the carbonization is completed, first close the main air inlet 8 of the main line 5, and open the main air outlet 9 to discharge the exhaust gas.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
