Carbon dioxide preparation device for underground fire prevention and extinguishing

Abstract

The invention relates to the technical field of carbon dioxide preparation, in particular to a carbon dioxide preparation device for underground fire prevention and extinguishing, which comprises a base and supporting legs, wherein the lower end face of the base is fixedly connected with the evenly-distributed supporting legs, the left side of the upper end face of the base is fixedly connected with a preparation tank, and the center of the upper end face of the preparation tank is fixedly connected with an air inlet tube; an alarm lamp is arranged on the left side of the air inlet tube, the lower end face of the alarm lamp is fixedly connected with the preparation tank, a display tube is arranged on the right side of the air inlet tube, and the lower end face of the display tube is fixedly connected with the preparation tank. According to the carbon dioxide preparation device, the water inlet tube, a heat exchanger, a cooling tube and a cooling water tube are arranged, the cooling tube is arranged on the outer side of the water inlet tube in a sleeving mode, a water source is arranged in the water inlet tube, hot CO2 is arranged in the cooling tube; and meanwhile, the hot CO2 can be cooled, the CO2 cannot make contact with the water source, the CO2 is prevented from being dissolved in water, and the water source can be cooled under the action of the heat exchanger; and then cold water can be recycled through the cooling tube, so that normal preparation of CO2 is ensured.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide preparation, in particular to a carbon dioxide preparation device for downhole fire prevention and extinguishing. Background technique [0002] Carbon dioxide is a colorless, tasteless and odorless gas at room temperature with the chemical formula CO 2 , formula weight 44.01, one of carbon oxides, commonly known as carbonic acid gas, also known as carbonic anhydride or carbonic anhydride, is a colorless, odorless gas at room temperature, slightly denser than air, soluble in water (1 volume H 2 O can dissolve 1 volume of CO 2 ), and generate carbonic acid, solid carbon dioxide, commonly known as dry ice, can absorb a lot of heat when sublimated, so it is used as a refrigerant, such as artificial rainfall, and is often used to make smoke in stage art (dry ice sublimates and absorbs heat, liquefies water vapor in the air) . [0003] Carbon dioxide for downhole fire extinguishing is generall...

AI Technical Summary

Problems solved by technology

[0003] Carbon dioxide for downhole fire extinguishing is generally prepared by the outside world, and then stored in the storage device, and most of the CO2 currently on the market 2 Generally, limestone is calcined at high temperature during preparation, and then the produced CO 2 collected, but CO 2 It needs to be cooled when it is collected. The traditional cooling method is to cool it through a cooler, but when the cooler is in use, it will generate water due to the temperature difference, and the CO 2 Soluble in water, at this time will cause some CO 2 Therefore, in view of the above problems, a carbon dioxide preparation device for underground fire prevention and extinguishing is proposed
