[0001] The present invention relates to the technical field of mining environmental protection equipment, and in particular to a separable mining carbon neutralization equipment. Background Art

[0002] Carbon neutrality refers to the measurement of the total amount of greenhouse gas emissions directly or indirectly generated by an enterprise, group or individual over a certain period of time, and the realization of "zero carbon dioxide emissions" by offsetting their own carbon dioxide emissions through tree planting, energy conservation and emission reduction. As a new form of environmental protection, it has been adopted by more and more large-scale events and conferences, promoting green life and production and realizing green development in the whole society.

[0003] Specifically, carbon neutrality means controlling the emissions of carbon dioxide. For places such as mines, due to the large amount of carbon dioxide emissions, they are places that need to be monitored closely in carbon neutrality.

However, there are many impurities in the gas in places such as mines, which can easily cause damage to the treatment equipment during treatment, especially the carbon neutralization equipment used in mines, which is more easily damaged by impurities in the gas. In the prior art, the gas is usually simply filtered before treatment.

The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and obvious to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be put into practice without these specific details.

[0035] It can be understood that, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another entity or operation, and are not intended to express or imply any actual relationship or order between these entities or operations.

[0036] The terms "comprises," "comprising," or any other variation thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0037] Reference Figures 1 to 8 As shown, a separable mining carbon neutralization device comprises a front-stage component 1 for separating carbon dioxide from gas, a rear-stage component 2 for adsorbing the carbon dioxide separated by the front-stage component 1, and an air pump 3 for allowing gas to enter the front-stage component 1 and allowing the carbon dioxide output by the front-stage component 1 to enter the rear-stage component 2; The front stage assembly 1 comprises a cylinder 11, in which a filter screen 12, a filter 13, a dust collector 14 and a separation membrane 15 are arranged, and the gas flows through the filter screen 12, the filter 13, the dust collector 14 and the separation membrane 15 in sequence; The rear stage assembly 2 includes an adsorption box 21 and an adsorbent 22 filled in the adsorption box 21; The air pump 3 is provided with a flow controller for controlling the flow of the air pump 3, the adsorption box 21 includes an exhaust pipe 23, the exhaust pipe 23 is provided with a post-sensor for detecting the carbon dioxide content in the exhaust pipe 23, and the outlet of the air pump 3 is provided with a pre-sensor for detecting the carbon dioxide content in the gas output by the air pump 3, and the air pump 3 is also provided with a controller, and the post-sensor and the pre-sensor both communicate with the controller; The gas enters the filter 13 from the filter screen 12, the filtered matter that does not pass through the filter screen 12 falls from the filter screen 12 under the action of gravity, and the gas that passes through the filter screen 12 enters the filter 13; Impurities in the gas entering the filter 13 are retained in the filter 13. The gas passing through the filter 13 is dust-removed by the dust collector 14 and then contacts the separation membrane 15. The carbon dioxide separated by the separation membrane 15 enters the air pump 3, and other gases separated by the separation membrane 15 are discharged. Specifically, the gas separated by the separation membrane 15 can be discharged directly, or the gas separated by the separation membrane 15 can also enter other processing equipment for other processing.

[0038] The gas entering the air pump 3 is output to the adsorption box 21 by the air pump 3. The gas is detected by the post-positioned sensor before entering the adsorption box 21. The gas entering the adsorption box 21 is adsorbed by the adsorbent 22 in the adsorption box 21 and then discharged from the exhaust pipe 23. The post-positioned sensor detects the carbon dioxide content in the exhaust pipe 23. The controller controls the flow controller according to the parameters detected by the front sensor and the rear sensor.

[0039] The air pump 3 is a common device in the prior art.

[0040] The front sensor and the rear sensor are common electronic components in the prior art.

[0041] The controller is a common electronic device in the prior art.

[0042] The flow controller may be a frequency converter. For example, the flow controller controls the flow of the air pump 3 by changing the rotation speed of the power element of the air pump 3 .

[0043] The flow controller may also be a flow control valve, that is, the flow control valve is used to control the flow of the gas entering the subsequent component 2.

[0044] The greater the gas flow rate entering the subsequent stage component 2, the shorter the reaction time between the gas and the adsorbent 22, and the worse the gas treatment quality. Conversely, the smaller the gas flow rate entering the subsequent stage component 2, the longer the reaction time between the gas and the adsorbent 22 or the more complete the reaction, the better the gas treatment quality. In practical applications, the flow rate of the gas entering the subsequent stage component 2 can be determined based on the carbon dioxide content in the gas.

[0045] Reference Figures 1 to 8As shown, in some embodiments, an air supply pipe 24 is provided in the adsorption box 21, and the air supply pipe 24 is connected to the air pump 3. The air supply pipe 24 is provided with a guide pipe 25, and the guide pipe 25 is communicated with the air supply pipe 24. The gas in the guide pipe 25 enters the adsorption box 21 from the bottom of the adsorbent 22.

[0046] The adsorbent 22 may be liquid, or may be solid, such as adsorbent particles, etc. Generally, the gas should contact the adsorbent 22 from the lower end of the adsorbent 22, and then the gas rises in the adsorbent 22, and contacts and reacts well with the adsorbent 22, thereby improving the gas treatment quality.

[0047] Since the gas enters the adsorbent 22 from below the adsorbent 22, the gas can also stir the adsorbent 22 when moving upward in the adsorbent 22, so that the gas has good contact performance with the adsorbent 22. No independent stirrer is required in the adsorbent 22.

[0048] The preferred adsorbent 22 in this embodiment is an adsorbent 22 in a liquid state.

[0053] The upper end of the air supply pipe 24 extends beyond the liquid level of the adsorbent 22 , which can prevent the adsorbent 22 from entering the air supply pipe 24 . The adsorbent 22 will not enter the air supply pipe 24 , thereby making the air pump 3 less likely to be damaged.

[0056] The explosion-proof sand 34 plays an explosion-proof function. In this solution, the air pump 3 is the only electrical component, and the motor may generate electric sparks during operation. By providing the explosion-proof sand 34, the motor explosion can be effectively avoided or the mine safety can be improved.

In addition, the mining carbon neutralization equipment will be assembled. In addition, the rear stage assembly 2 is located above the front stage assembly 1, and the mining carbon neutralization equipment occupies a small space.

[0059] In some embodiments, the filter 13 is a sand filter filled in the cylinder 11 . A partition 17 is also provided in the cylinder 11 . The partition 17 is located between the dust collector 14 and the filter 13 .

[0060] The gravel filter refers to gravel filled in the cylinder 11, and filtering is performed using the gaps between the gravel.

[0061] In some embodiments, the dust collector 14 includes a sealed cavity 141, which is filled with dust removal liquid 412. An air inlet pipe 18 is provided in the sealed cavity 141, and the upper end of the air inlet pipe 18 extends out of the liquid surface of the dust removal liquid 412.

[0062] The dust removal liquid 412 may be water.

[0063] The cylinder 11 can be integral or split.

[0064] When the cylinder 11 is split, the sealing performance of the sealing cavity 141 should be ensured. For example, the partition plate 17 can be welded to a part of the cylinder 11.

It can be understood that the above description is only some implementation plans of the subject technical solution of the present invention, and some details may be omitted during the specific implementation.

[0066] In addition, in some embodiments of the above invention, multiple embodiments may be implemented in combination, and various combinations are not listed one by one due to space limitations.
