Embodiment Construction

[0015] The specific implementation, structure, features and effects provided by the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0016] Such as figure 1 A kind of processing technology of the hazardous waste discarded acid that shows violent reaction with water, it comprises the following steps:

[0017] (1) Open the packaging container. Since the air contains moisture, the waste acid reacts with water, and acid gas will emerge from the packaging outlet. The acid gas is absorbed into the absorption tank through the ventilation device, and it is not directly discharged into the atmosphere, which will not cause secondary pollution to the environment. At the same time, the negative pressure generated by the vacuum pump is used to transport the waste acid to the feeding tank.

[0018] (2) The feeding tank is in a sealed state, and the exhaust pipe is connected to the ventilation device, and a small...

Abstract

The invention relates to a process of treating hazardous wastes and waste acids capable of violently reacting with water. The process can reduce the contact of operating staff with acids and control the concentration of acid gas generated during the dissolution and dilution procedures in the treatment of hazardous wastes and waste acids, can effectively absorb the generated acid gas to eliminate risk factors, and can safely and effectively treat the hazardous wastes and waste acids capable of violently reacting with water in an environment-friendly manner without generating damage to human beings or secondary pollution to the environment.

Description

technical field [0001] The invention belongs to the field of waste treatment technology, and relates to a treatment process for waste acid of hazardous waste that reacts violently with water, and is especially suitable for safe and effective treatment of waste acid of hazardous waste that reacts violently with water without harming It will cause harm to people and will not cause secondary pollution to the environment. Background technique [0002] In the process of using acid, due to various reasons, it can no longer be used normally. Long-term storage will cause potential harm to personnel and the environment. Improper storage, such as poor airtightness, humidity, etc., will react and produce acid gas, which is harmful to personnel and the environment. Harmful to different degrees caused by equipment and other equipment, it is necessary to carry out harmless treatment in time. During the treatment process, due to the high concentration of this acid, it cannot be treated di...
