Vertical rotating bed super gravity field equipment

Abstract

The invention is a vertical rotating bed supergravity field equipment, which is used for strengthening physical and chemical reactions between phases in water treatment and atmospheric treatment in the environmental protection industry, and is also suitable for mass transfer of multi-phase systems in various chemical industries and reaction process. It includes a barrel-shaped upright casing with an air inlet on the side, a vertical rotating body in the middle of the casing, a waste liquid return outlet at the bottom of the casing, an air guide barrel in the middle of the rotating body, and a There is an air inlet, the top of the air guide barrel is connected with the demister, the side wall of the rotating body is a rotating packing bed, the whole rotating body is connected with the transmission device that provides power, and at least three sets of supporting guides are arranged on the upper part of the rotating body The wheels form an inscribed circle, and the rotating body rotates according to the position defined by the inscribed circle to support and guide the rotation of the rotating body. At least three sets of supporting guide wheels are used to support the rotating body to rotate stably and reliably when both ends are supported, and the diameter and volume of the rotating body can be increased for the treatment of large volumes.

Description

technical field [0001] The invention relates to a device for gas-liquid heat and mass transfer and reaction, in particular to a device for strengthening gas-liquid, liquid-solid and liquid-liquid reactions by utilizing the supergravity field generated by a rotating bed. It is suitable for the strengthening of physical and chemical reactions between phases in water treatment and air treatment in the environmental protection industry, and is also suitable for mass transfer and reaction processes of multi-phase systems in various chemical industries. Background technique: [0002] High-gravity field rotating equipment, namely Rotating Packed Bed (RPB) is a new type of equipment developed in the early 1980s, which uses high-speed rotating packing to create a high-gravity environment. In this supergravity field, the molecular diffusion and interphase mass transfer process between molecules of different sizes are much faster than in the conventional gravity field.

Problems solved by technology

In addition, when the above-mentioned rotating arrangement of the vertical axis is used for desulfurization and dust removal, due to the presence of a large amount of dust and acid gas in the intake air, the weight of each part of the rotating disc or wire mesh is often different due to high-speed friction and corrosion, which is very difficult. It is easy to damage and ensure the stability during high-speed rotation, which makes the dynamic balance that is very concerned about the design and processing of the device meaningless

Therefore, these devices are difficult to be effectively and long-term applied in actual production
