Description

Technical Field

[0001] The invention relates to the technical field of environmental protection technology and is a deep-buried storage device for carbon dioxide. Background Art

[0002] Carbon dioxide is a major greenhouse gas, and its emission has a significant impact on global climate change. In order to reduce carbon dioxide emissions and respond to climate change, deep burial storage technology has been widely studied and applied. Deep burial storage is a technology that can effectively reduce the release of carbon dioxide into the atmosphere by storing carbon dioxide gas underground for a long time. This technology involves capturing carbon dioxide and compressing it into a supercritical state, and then transporting it to a suitable geological layer, and permanently fixing it underground through geological sequestration. Commonly used geological layers include oil and gas fields, aquifers, and deep saline layers. The main advantage of deep burial storage technology is that it can reduce carbon dioxide emissions on a large scale and store carbon dioxide permanently underground to prevent it from entering the atmosphere. In addition, deep burial storage technology can also be combined with other carbon dioxide emission reduction measures (such as carbon capture and utilization technology) to form a comprehensive carbon emission reduction solution. However, deep burial storage technology also faces some challenges, such as the selection and evaluation of storage geological layers, storage safety and monitoring, and the cost and efficiency of the transmission and injection process.

[0003] Current deep buried carbon dioxide storage devices have some technical challenges and threats to storage safety. In the deep buried storage devices, carbon dioxide is compressed into a high-density supercritical state and stored underground. However, the cooling effect of carbon dioxide may not be ideal, resulting in an increase in temperature, which may have a negative impact on the physical properties and sealing of the geological layer, increasing the risk of carbon dioxide leakage. The storage device is buried deep underground, and crustal movement may affect the storage geological layer, breaking its sealing and increasing the risk of carbon dioxide leakage. Based on this, the present invention provides a deep buried carbon dioxide storage device to solve the problems raised in the above-mentioned background technology. Summary of the invention

[0009] The above-mentioned buffer mechanism may include a mounting seat, a buffer seat, a buffer rod, a buffer spring, and a buffer groove. The mounting seats are symmetrically arranged on both sides of the upper inner side of the tank body, and buffer rods are symmetrically arranged on both sides of the mounting seat. A buffer seat is arranged on the side of the mounting seat away from the buffer rod. A buffer spring is arranged on the buffer rod between the buffer seat and the mounting seat, and a buffer groove is opened in the buffer seat, and the buffer seat and the mounting seat cooperate with each other.

[0010] The buffer seat described above may be in a U-shaped structure, and the buffer seat and the inner cavity cooperate with each other.

[0011] The present invention has a reasonable structure and has the following beneficial effects: 1. The cooling trough is located below the cooling box, and multiple cooling pipes are arranged inside. The cooling pipes are located above the limit frame. The coolant is pumped out from the water tank by the pump and transported to the transmission trough through the delivery pipe. Due to the cooperation between the block and the cooling pipe, the block can control the coolant to enter the cooling pipes in different areas. A fixed plate is provided above the transmission trough, and a groove is provided on the upper surface of the fixed plate. This groove can cooperate with the sealing gasket on the push rod to prevent the liquid from entering the upper part and affecting the bidirectional motor. The bidirectional motor is installed on the motor seat and is started by control to work. The bidirectional motor can drive the turntable to rotate. A convex block is provided on one side of the turntable, and a push rod is provided in the groove. When the turntable rotates, the convex block can drive the push rod to move vertically in the groove. The baffle is located on the side of the push rod away from the transmission plate, and is used to block the movement of the push rod. By adjusting the position of the baffle, the vertical movement range of the push rod can be controlled. After the coolant is transported to the transmission groove, it can be dissipated through the cooling pipe and the objects in the tank body can be cooled. The block is located below the baffle and cooperates with the cooling pipe to control the coolant to enter the cooling pipes in different areas. Through the rotation of the bidirectional motor and the vertical movement of the push rod, the cooling box realizes the circulation of the coolant, and dissipates heat and cools the objects in the inner cavity through the cooling pipe. At the same time, the baffle and the block can control the coolant to enter the cooling pipes in different areas to meet the cooling needs of different parts. The use of sealing pads can prevent liquid from entering the upper part and protect the normal operation of the bidirectional motor.

[0012] 2. The drop pipe is located inside the storage tank. This design allows appropriate liquid or material to be injected into the anti-coagulation mechanism through the injection box, and then the liquid or material is guided to the storage tank through the drop pipe. A guide pipe is arranged away from the injection box, and a spray rack is arranged on one side of the guide pipe. This design allows the liquid or material to flow smoothly from the drop pipe into the guide pipe and be sprayed through the spray rack. Nozzles are arranged at equal distances on the spray rack. The nozzles can evenly spray or disperse the liquid or material and ensure that it can cover the required area. The range and intensity of the spraying can be controlled to meet the needs. A filter is arranged between the guide pipes on both sides, and the filter is a detachable device. The filter is used to capture impurities and particulate matter in the anti-coagulation mechanism and prevent them from entering the spray rack and the nozzle. Since the filter is detachable, the filter can be cleaned or replaced regularly to maintain the good operation and spraying effect of the anti-coagulation mechanism.

[0013] 3. The mounting seat is a support seat fixed on both sides of the upper inner side of the tank body, which is used to support and install the buffer seat and the buffer rod. The function of the buffer rod is to support the buffer seat and allow the buffer seat to move and deform during operation. The buffer seat is a U-shaped structure part, which is installed on the buffer rod and cooperates with the mounting seat. The buffer seat and the inner cavity also cooperate with each other. When the buffer mechanism is working, the buffer seat can move up and down on the mounting seat and can be deformed as needed. The buffer spring is arranged between the buffer rod and the buffer seat. The buffer spring provides elastic force to provide buffering and shock absorption effects during operation. When external force acts on the buffer mechanism, the buffer spring will be compressed or stretched, thereby absorbing the impact force and reducing the impact on the inner cavity.
