Abstract
Description
Technical Field
[0001] The utility model relates to the field of industrial acid production, in particular to a negative pressure monitoring connection structure outside an acid distributor tower. Background Art
[0002] The acid separator is a tower accessory that evenly distributes the acid to the surface of the packing on the top of the packing. The acid separator is a key environmental protection equipment in the sulfuric acid industry to remove moisture from SO2 gas and absorb SO3 gas to prepare sulfuric acid. During the operation of the acid separator, since it operates in a closed space of the tower body, its operating status can only be judged indirectly from the outside. When problems are found, the machine needs to be shut down for maintenance, which affects efficiency.
[0003] For example, Chinese patent: Publication No. CN213023985U discloses a system for remotely monitoring and controlling the equal distribution of sulfuric acid, including an industrial control device, which includes a negative pressure transmitter, a processor and a negative pressure pump. Both the negative pressure transmitter and the negative pressure pump are connected to an acid distributor, and the processor is electrically connected to the negative pressure transmitter and the negative pressure pump, respectively. The processor receives vacuum data in the acid distributor transmitted by the negative pressure transmitter, and the processor can control the start and stop of the negative pressure pump.
[0004] Although the utility model has greatly improved the fluctuations in production conditions and process conditions and the influence of the air pressure in the dry absorption tower on the equal distribution of sulfuric acid by means of the industrial control device, it is simple to operate and highly practical, and can greatly improve the yield of sulfuric acid, thereby greatly improving the production efficiency of sulfuric acid. However, the negative pressure lead-out may be blocked by accumulated liquid, affecting the negative pressure detection, and when the instantaneous flow rate increases, the acid overflows and easily damages the negative pressure gauge. At the same time, the vibration of the lead-out pipe can easily cause it to fall off or damage the negative pressure gauge.
