Description

Technical Field

[0001] The utility model relates to the technical field of waste gas emission, in particular to a clean workshop acid and alkali waste gas emission device. Background Art

[0002] A clean workshop, also known as a dust-free workshop or clean room, refers to a specially designed room that removes pollutants such as particles, harmful air, and bacteria from the air within a certain space range, and controls the indoor temperature, cleanliness, indoor pressure, airflow speed and distribution, noise vibration, lighting, and static electricity within a certain required range. When processing some parts, a certain amount of acid and alkali waste gas will be generated. When acid and alkali waste gas is generated, it is generally necessary to absorb and discharge the acid and alkali waste gas of the clean workshop through an emission device. The existing clean workshop acid and alkali waste gas emission device generally has an emission power range that cannot exceed this range for higher power emission. When the workbench acid and alkali waste gas is generated at a faster speed and in larger quantities, the suction efficiency of the acid and alkali waste gas emission device in the workshop may not be able to keep up with the speed of waste gas generation due to the large diameter and unconcentrated suction force. Therefore, we need a gathering mechanism that can concentrate the suction force of the air inlet according to the needs of the user; therefore, a clean workshop acid and alkali waste gas emission device is proposed to address the above problems.

[0003] The above information disclosed in the background technology section is only used to enhance the understanding of the background of the present invention and therefore may contain information that does not constitute the prior art known to ordinary technicians in this field.
