Geological storage method of industrial tail gas and supporting equipment

Abstract

The invention relates to an industrial tail gas geological storage method and a supporting apparatus thereof. The method concretely comprises: 1, capturing and conveying flue gas through an induced fan; 2, carrying out a gradual broadening-gradual contracting balance and acceleration treatment during the flue gas conveying process to make the flue gas directly reach a gas flow speed change device; 3, conveying the speed changed flue gas to an underground geological absorption desorption chamber through a frictional pipeline; and 4, finally intercepting the entering flue gas, filtering, carbonizing, and carrying out desublimation treatment so as to adsorb and store the flue gas. According to the present invention, the method is achieved through the following apparatus, wherein the apparatus sequentially comprises an overground negative pressure absorption flue pipe, an induced fan, a gradual broadening-gradual contracting positive pressure sound speed pipe, a gas flow speed changer device, a frictional flue channel pipe, an underground dust intercepting chamber, a plurality of sand-stone separation membrane meshes, an anti-seepage separation layer, a sulfur dioxide desorption chamber, a carbonization storage chamber and the like according to the flow sequence, wherein the plurality of the sand-stone separation membrane meshes and the anti-seepage separation layer are arranged inside the underground dust intercepting chamber, and the flue gas is subjected to decomposition desublimation and absorption desorption in the apparatus so as to achieve the zero emission of the flue gas.

Description

technical field [0001] The invention relates to the field of environmental protection and control of harmful gases, in particular to a method and device for sealing industrial tail gas. Background technique [0002] Environmental pollution and human health damage caused by industrial tail gas and dust have been problems that have existed since the establishment of the industry. Although all parts of the world are actively carrying out equipment transformation and anti-pollution treatment, they are mainly implemented in the control of dust and sewage discharge On the one hand, industrial tail gas is not treated enough due to technical factors. Later, with technological progress and the requirements of the situation, although more attention and efforts have been made, it has mainly focused on the desulfurization and emission reduction of sulfur dioxide, but has not yet found a better solution for the treatment of carbon monoxide, carbon dioxide and nitrogen oxides. Solution. ...

[0003] Search literature, there is the method disclosed in CN102207243A, which is quite similar to underground storage, but this is a chemical method, which uses carbon dioxide to dissolve limestone for underground storage, which is not ideal, mainly because of different service methods, complex and cumbersome processes and The operation cost of chemical reaction process is high, and it is necessary to have a limestone layer near the ground surface in the factory area. However, it is difficult to have such objective conditions in many polluted enterprise areas, and it is also very deep from the ground, so it is difficult to realize
