Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the present invention includes a vertically arranged first cylinder section 1, the upper end of the first cylinder section 1 is tightly connected to an upper sealing cover 2, and the lower end of the first cylinder section 1 is connected to a second cylinder section through a flange 3 4, the lower end of the second cylinder section 4 is tightly connected to the lower sealing cover 20, an air outlet 6 is set on the upper sealing cover 2, and a liquid CO is provided on the lower sealing cover 20. 2 Outlet 7 and a sewage outlet (not shown in the figure). The upper part of the second cylinder section 4 is provided with a packing 10 supported by a support plate 9, and the packing 10 is used to promote liquid CO 2 with dissolved O 2 separate. A feed pipe 8 is arranged on the cylinder wall of the second cylinder section ...

Abstract

The invention provides a purifying tower. The purifying tower comprises a closed cylinder. A gas outlet is formed in the top of the cylinder. A liquid CO2 outlet and a sewage discharge opening are formed in the bottom of the cylinder. The lower portion in the cylinder is fixedly connected with a coil used for gas heat exchange. The inlet and the outlet of the coil both penetrate out of the bottom of the cylinder. Filler supported by a supporting plate is arranged above the coil. A feed pipe is arranged on the portion, above the filler, of the cylinder wall of the cylinder. The CO2 purifying tower is high in separation efficiency, can effectively separate O2 and CO2, can further purify CO2, and is used for recycling by-products of a supercritical water oxidization technical system. Due to the fact that the lower portion in the cylinder is fixedly connected with the coil used for gas heat exchange, CO2 can be further purified, O2 in liquid CO2 can be separated out, and meanwhile gas is preliminarily cooled through cold energy of liquid CO2.

Description

technical field [0001] The invention relates to a purification tower, which belongs to the field of harmless treatment of organic waste. Background technique [0002] The petrochemical industry is one of the pillar industries of our country. While bringing huge economic benefits to the national economy, it also puts enormous pressure on environmental protection. In recent years, the increasing pollution of toxic organic substances in water bodies is closely related to the rapid development of the petrochemical industry and the discharge of a large amount of organic chemical wastewater. The wastewater discharged from the organic chemical industry is often complex in composition, high in concentration, highly toxic, dark in color, and difficult to biodegrade. If traditional oxidation, biochemical and other destruction methods are used for treatment, a large amount of chemical raw materials or products will be decomposed and destroyed, resulting in waste loss, which not only i...
