Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide, and in particular to a carbon dioxide compression device. Background Technology

[0002] Carbon dioxide is a colorless and odorless gaseous compound composed of one carbon atom and two oxygen atoms bonded together by covalent bonds. It plays an important role in the carbon cycle in nature. In the industrial field, carbon dioxide is an important chemical raw material that can be used to produce carbonated beverages, dry ice, urea, etc. In agriculture, applying carbon dioxide as fertilizer can improve the photosynthetic efficiency of crops.

[0003] However, it is difficult to pre-treat carbon dioxide gas during the compression process. Untreated carbon dioxide gas is often mixed with impurities such as water vapor, dust, and sulfides. Water vapor will condense into liquid water during compression, which will accelerate the electrochemical corrosion of metal equipment. Dust particles will aggravate the mechanical wear of key components such as compressor blades and pistons under the scouring of high-speed airflow. Sulfides will corrode the inner wall of the equipment and reduce the purity of carbon dioxide, affecting the quality of downstream products. To address these issues, we propose a carbon dioxide compression device. Utility Model Content

A support seat is fixedly connected to the upper surface of the supporting base plate, and the upper surface of the support seat is fixedly connected to the bottom surface of the filter cover.

[0010] In a further embodiment, the output end of the compressor is fixedly connected to an exhaust pipe, and the top end of the exhaust pipe is fixedly connected to an exhaust flange.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a first and a second filter screen inside the filter cover to efficiently intercept dust particles. Larger particles are first blocked by the first filter screen, while the second filter screen further removes finer particles, preventing dust from causing wear on compressor blades, pistons, and other components during compression. In addition, the molecular sieve plate and activated carbon adsorption layer inside the adsorption cylinder allow the molecular sieve to adsorb water vapor, preventing liquid water from causing electrochemical corrosion of the equipment, while the activated carbon adsorption layer adsorbs sulfides, preventing them from corroding the inner wall of the equipment and improving the purity of carbon dioxide. Thus, this compression device achieves the effect of pre-treating carbon dioxide gas. Attached Figure Description

The outer surface of the first sealing cap 9 is fixedly connected to a first connecting pipe 10. Utilizing the molecular sieve plate 11 and activated carbon adsorption layer 12 inside the adsorption cylinder 4, after the gas enters the adsorption cylinder 4 from the first connecting pipe 10, it first passes through the upper molecular sieve plate 11, which uses its microporous structure to adsorb water vapor and small molecule impurities, and then passes through the lower activated carbon adsorption layer 12, whose rich pore structure adsorbs organic impurities such as sulfides, thus achieving deep purification of the gas.

[0022] In a further embodiment, the filter assembly 3 includes a filter cover 301, the inner ring of which is threadedly connected to a first filter screen 303 and a second filter screen 302, one end of the first connecting pipe 10 is movably connected to a second connecting pipe 5, one end of the second connecting pipe 5 passes through the filter cover 301 and extends into the interior of the filter cover 301, a second threaded connecting seat 304 is fixedly connected to the outer surface of the filter cover 301, the inner ring of the second threaded connecting seat 304 is threadedly connected to a second sealing cap 305, and one end of the second sealing cap 305 is fixedly connected to an injection pipe 306.

The gas after preliminary filtration enters the adsorption cylinder 4 through the second connecting pipe 5 and the first connecting pipe 10. Inside the adsorption cylinder 4, the gas first passes through the molecular sieve plate 11 above, which uses the adsorption characteristics of the molecular sieve to remove water vapor and some small molecule impurities. Then it passes through the activated carbon adsorption layer 12 below. The porous structure of the activated carbon can adsorb organic impurities such as sulfides and odor substances, completing deep purification. The pre-treated carbon dioxide gas enters the compressor 2 through the air inlet pipe 13 for compression. The compressed carbon dioxide gas is discharged through the exhaust pipe 15 and transported to the subsequent equipment through the exhaust flange 14.
