Battery cupboard exhaust device

Abstract

The invention discloses a battery cupboard exhaust device. The device comprises a cupboard body and an exhaust fan, wherein a controller is fixedly connected with the upper end of the left side outside the cupboard body; an electronic louver is arranged on the left side of the cupboard body; a hydrogen sensor I is arranged at the top inside the cupboard body; a vent hole is formed in the right side of the cupboard body, and a vent pipeline is arranged at the right end of the vent hole; an activated carbon filter screen is embedded into the left side inside of the vent pipeline, and a hydrogenstorage alloy filter screen is embedded into the right side inside the vent pipeline; after the hydrogen concentration of the hydrogen sensor I reaches a certain value, the electronic louver is openedto exhaust air, the alloy reacts with hydrogen to generate a metal hydride when hydrogen is stored, and hydrogen stored in the metal hydride is released by heating when hydrogen is required. The battery cupboard exhaust device is reasonable in design, can effectively solve potential safety hazard of a battery cupboard caused by waste gas, and is applicable to production and popularization.

Description

Technical field [0001] The invention belongs to the technical field of waste treatment, and particularly relates to a battery cabinet exhaust device. Background technique [0002] In the field of lead-acid batteries, several lead-acid batteries are generally installed in a lead-acid battery storage device such as a cabinet for use. Lead-acid batteries will have a certain amount of gas escape in the later stage of charging, most of which are hydrogen. The gas treatment method is to discharge hydrogen to the lead-acid battery through the safety valve on the lead-acid battery. Therefore, the air in the lead-acid battery storage device will be mixed with hydrogen; the lead-acid battery storage device is a relatively closed space. When the content reaches a certain percentage, there is a danger of explosion. In order to solve this problem, a fan is generally introduced into the lead-acid battery storage device, and the working frequency of the fan is set, such as working every few hou...

AI Technical Summary

Problems solved by technology

[0002] In the field of lead-acid batteries, generally a number of lead-acid batteries are placed in a lead-acid battery pack storage device such as a cabinet for use together. A certain amount of gas will escape from the lead-acid battery in the later stage of charging, most of which are hydrogen. Traditionally The gas treatment method is to discharge the hydrogen gas from the lead-acid battery through the safety valve on the lead-acid battery, so the air in the storage device of the lead-acid battery will be mixed with hydrogen; the storage device of the lead-acid battery is a relatively closed space, when hydrogen When the content reaches a certain ratio, there is a danger of explosion. In order to solve this problem, a fan is generally introduced into the storage device of the lead-acid battery pack, and the working frequency of the fan is set. The device is ventilated to the outside to reduce the hydrogen content in the air of the lead-acid battery storage device; although this exhaust method reduces the hydrogen concentration in the lead-acid battery storage device to a certain extent, it cannot remove the lead-acid storage device. The hydrogen in the storage device is completely discharged, and there is still a hidden danger of hydrogen explosion; hydrogen is a good clean energy source. If the hydrogen in the waste gas can be recovered, it will reduce safety hazards and turn waste into treasure
