Abstract
Description
Technical Field
[0001] This utility model relates to a carbon monoxide purification device, belonging to the technical field of gas purification equipment in the metallurgical industry. Background Technology
[0002] Currently, some laboratories need to use carbon monoxide as a reducing gas in their experiments. However, the amount of carbon monoxide used is extremely small and the frequency of use is low. Purchasing high-purity carbon monoxide is costly and involves long storage periods, posing significant safety hazards. If carbon monoxide is prepared by reacting charcoal with carbon dioxide, the charcoal contains untreated organic matter and fumes generated during the reaction. These substances will enter subsequent processes along with the generated gas. Long-term use will cause the gas pipelines and flow meters of the equipment to become blackened and adhered to by substances. This will result in viscous organic matter entering the gas flow meters, leading to inaccurate measurements and affecting experimental results.
[0003] Therefore, it is necessary to design a carbon monoxide purification device to remove trace amounts of volatiles and fumes generated during the reaction from the carbon monoxide. Utility Model Content
[0004] The purpose of this invention is to provide a carbon monoxide purification device that can collect, filter dust, and absorb moisture from the liquefied organic matter in carbon monoxide prepared by the reaction of charcoal and carbon dioxide, thereby meeting the requirements of experimental equipment and solving the problems existing in the background technology.
[0005] The technical solution of this utility model is:
[0006] A carbon monoxide purification device includes a sleeve, a flange cover, an air inlet, an air outlet, perforated plates, color-changing silica gel, soda lime, filter cotton, and a flange base. The sleeve has a flange cover and a flange base at its upper and lower ends, respectively, forming a sealed chamber between the flange cover, flange base, and sleeve. Three perforated plates are arranged vertically inside the sleeve, dividing the interior into four vertically arranged spaces. From top to bottom, the color-changing silica gel is placed in the uppermost space, the soda lime in the second space, and the filter cotton in the third space. The flange cover has an air outlet, and the flange base has an air inlet.
[0007] The flange cover and the flange base are connected by a lead screw.
[0008] The flange cover and flange base are respectively provided with sealing rings between them and the sleeve.
[0009] The vent on the flange cover is located in the center of the flange cover, and the vent on the flange base is located on the side of the flange base.
[0010] The perforated plate is provided with evenly arranged ventilation holes.
[0011] The beneficial effects of this invention are as follows: carbon monoxide containing impurities enters the device through the bottom flange air inlet and diffuses upward; the filter cotton filters the dust in the carbon monoxide; the soda lime absorbs the moisture in the carbon monoxide; and the color-changing silica gel detects the moisture absorption, so as to obtain carbon monoxide gas that meets the test requirements.
