Carbon dioxide storage and deep burying device applying carbon neutralization

Abstract

The invention discloses a carbon dioxide storage deep burying device applying carbon neutralization, which comprises a liquid-phase carbon dioxide storage tank, a shield pump, a high-pressure pump, a heat exchanger and a boiler, the output end of the liquid-phase carbon dioxide storage tank is divided into a gas-phase path and a liquid-phase path, the liquid-phase path passes through a plurality of stop valves, a high-low pressure manifold and the shield pump to reach a first inlet end of the high-pressure pump, and the liquid-phase path passes through a second inlet end of the high-pressure pump; one gas phase path reaches a second inlet end of the high-pressure pump through a plurality of stop valves and a back pressure valve and reaches an outlet end of the high-pressure pump through a return valve, the outlet end of the high-pressure pump reaches an input end of the heat exchanger through a first one-way valve, and an output end of the heat exchanger is communicated with a wellhead pressure injection pump through a second one-way valve; the hot water output end of the boiler is connected with a circulating pipeline of the heat exchanger through a hot water pump. The device is simple and compact in structure and low in use cost, carbon dioxide is liquefied, stored and deeply buried underground, and the remarkable effect is achieved in the aspects of preventing the temperature of the earth from rising, preventing the sea level from rising continuously and the like.

Description

technical field [0001] The invention relates to a carbon dioxide emission reduction device, in particular to a device for deeply burying stored liquid-phase-liquid-phase mixed carbon dioxide after being heated, and belongs to the technical field of environmental protection. Background technique [0002] Global average temperatures are rising due to increasing emissions of gaseous carbon dioxide. If active measures to reduce carbon dioxide emissions are not taken, the global average temperature will continue to increase by 1.4°C to 5.8°C from now to 2100. At that time, Antarctica’s glaciers will melt faster, and sea levels will continue to rise, threatening the survival of many island countries in the Pacific Ocean and the Indian Ocean. Safe, and lead to the prevalence and spread of some diseases related to warm climates such as malaria and dengue fever, and may also induce frequent occurrences of extreme weather such as droughts and floods. The dramatic rise in global tempe...

Problems solved by technology

[0003] The existing recovered liquefied carbon dioxide is generally used in carbon dioxide gas shielded welding and carbonated beverages. Such a recycling method essentially still discharges carbon dioxide into the atmosphere twice, and does not fundamentally solve the problem of carbon dioxide emissions.
