Description
Technical Field
The utility model relates to the technical field of desulfurization devices, in particular to a tetrafluoro baffle plate demister.
Background
Wet desulfurization is a common industrial flue gas desulfurization treatment method, such as ammonia method, sodium method and limestone-gypsum method, in the desulfurization process, the small slurry particle size is helpful for the rapid gas-liquid reaction, however, the desulfurized flue gas is saturated with slurry droplets, and the small-particle-size droplets are easily carried and discharged by the gas flow, so that the pollution and serious corrosion of a fan, a heat exchanger and a flue are caused, and therefore, the purified flue gas needs to be defogged before leaving an absorption tower. The demister with small pressure loss, high air flow speed and high demisting efficiency is an important link for ensuring the normal operation of a wet flue gas treatment process system. The demisting efficiency of the demister is increased along with the increase of the airflow speed, and the demister is beneficial to gas-liquid separation due to the fact that the flow speed is high and the inertia force acting on mist drops is large. However, an increase in flow rate will result in an increase in system resistance and also an increase in energy consumption. And the flow rate is increased by a certain limit, and the excessive flow rate can cause secondary water entrainment, thereby reducing demisting efficiency. The flow rate of flue gas through the demister cross section that is highest and not secondarily hydrated is generally defined as the critical flow rate, which is related to factors such as demister structure, system water loading, airflow direction, demister arrangement, etc.
The high-efficiency baffle mist catcher is particularly suitable for a tower, and is particularly suitable for a top or side line gas phase outlet of the tower so as to remove mist liquid drops, liquid foam and trace solid particles entrained in gas phase. Especially when the gas phase contains trace solid particles and crystals, the novel high-efficiency baffle plate foam (mist) remover has stronger anti-blocking performance and is not replaced by a silk screen foam remover.
The fixing mode of the existing demister baffle is generally to fix the baffle by clamping grooves on the baffle through clamping strips on the upper side and the lower side of the baffle, such as a baffle demister with good demisting effect of CN209662812U, a baffle demister with high resistance of Wen Sheliu U of CN205886412U, and the fixing mode can enable the baffle to shake greatly when air flow is large, so that demisting effect is affected.
