Abstract

The invention discloses an acid-process biological desulfurization device which comprises a desulfurization column, a nutritive salt tank and a tap water pipeline, wherein the bottom of the desulfurization column is connected with an aeration tank through a pipeline, the aeration tank is connected with an aeration pump through a pipeline, and the upper part of the aeration tank is connected to thetop of the desulfurization column through a pipeline and a circulating pump; the nutritive salt tank is connected to the aeration tank through a pipeline so as to convey nutritive salt into the aeration tank, and the tap water pipeline is also connected to the aeration tank. The invention also discloses an acid-method biological desulfurization process utilizing the device.

Description

technical field [0001] The invention relates to the technical field of desulfurization, in particular to an acid desulfurization device and process. Background technique [0002] The existing acid desulfurization device includes a desulfurization tower and a nutrient salt pool. The desulfurization tower is equipped with biological fillers, and the nutrient salt pool delivers nutrient salt to the bottom of the desulfurization tower. The nutrient salt solution is pumped to the top of the desulfurization tower by a circulating pump, and flows through the biological Filling, the bottom of the desulfurization tower is fed with biogas, and the biogas is in contact with the biological filler during the rising process to complete the desulfurization. [0003] The problems existing in the existing desulfurization device and process are: 1) the treatment effect is only 80%-90%; 2) the filling of the desulfurization tower contains a large amount of elemental sulfur, the tower will be b...
