Carbon dioxide elimination machine

Abstract

The invention provides a carbon dioxide elimination machine, comprising a control system, a fan, ventilation pipelines, solenoid valves, an electric heater, an absorption bed, an adsorption material and a post-filtration absorption bed, wherein the adsorption material loaded in the absorption bed is anion exchange resin, and an active carbon absorbent is loaded in the post-filter absorption bed, and the connection relation among the parts is that two paths of ventilation pipelines are converged and then communicated with an air inlet of the fan, one path is communicated with air in a storage,and the other path is communicated with outdoor air; and the pipeline of the air outlet of the fan is divided into two paths, one path directly leads to the air inlet of the absorption bed, the otherpath is connected with the electric heater and then leads to the air inlet of the absorption bed, the ventilation pipeline of the air outlet of the absorption bed is divided into two paths, one path leads to outdoor, the other path passes through the post-filter absorption bed and leads to the storage, each path of pipeline is provided with the solenoid valve, and the control system and the electric heater are connected with all the solenoid valves. The invention can be used for controlling the CO2 concentration in controlled atmosphere cold storage to be within 1-10%, and is small in size and suitable for being installed on ships.

Description

Technical field: [0001] The invention relates to a carbon dioxide remover, which belongs to the field of mechanical structures. Background technique: [0002] In agricultural controlled atmosphere storage, CO 2 The concentration has a direct impact on the storage period of agricultural products stored in the fresh-keeping warehouse. At present, the domestic equipment cannot control the CO of the controlled atmosphere warehouse very well. 2 concentration, the Italian PCE company's products are relatively good, but only CO 2 The concentration is controlled above 3%, and when the concentration needs to be controlled below 3%, the equipment needs to run for a long time. Invention content: [0003] The invention proposes a carbon dioxide removal machine, which can reduce the concentration of carbon dioxide in a controlled atmosphere fresh-keeping store to 1%-10%, effectively improve the storage effect of the controlled atmosphere store on fruits and vegetables, and prolong th...
