Embodiment 1

[0033] like figure 1 As shown, the present invention provides a deacidification circulation system, which includes a control device and a control system connected with a deacidification tower 1, a reaction tank 4 and a filter press 6, and the reaction tank 4 is used for deacidification through the set lye input pipeline 2. The tower 1 provides alkaline liquid, and the reaction tank 4 is provided with a feeding device 3 to provide calcium hydroxide alkaline substance for the reaction tank 4. A number of adjacent partition plates 8 are arranged inside the reaction tank 4. The partition plates 8 divide the reaction tank 4 into several sub-pools that are connected to each other and are arranged in sequence. The openings of the adjacent partition plates 8 The staggered arrangement allows the lye in it to circulate and flow around, wherein a mixer 5 is arranged in the middle of the front sub-pool, and the sub-pool at the rear is connected to the input pipeline 2, and the input pipel...

Embodiment 2

[0047] This embodiment is further improved on the basis of Embodiment 1. The difference is that: the deacidification cycle system provided in this embodiment is designed to allow the material 108 deacidified by the alkali solution to be quickly dried and the surface of the material 108 to be clean. , the inner cavity 113 is provided with a plurality of second air nozzles 117 on the side wall of the lower side of the diffuser 109. The second air nozzles 117 are connected with the second branch air intake pipe 104 through the air pipe, and the second branch air intake pipe 104 is provided with a control The second valve 105 connected to the device is connected to the control device, and the second air nozzle 117 is set in the downward direction and facing the material 108. Before the material 108 is taken out, use the control device to open the second valve 105 and perform 5-10 on the material 108. minutes of blowing.

Abstract

The invention relates to the technical field of deacidification equipment, in particular to a deacidification circulating system and a deacidification process. According to the deacidification circulating system and the deacidification process provided by the invention, the deacidification tower is electrically connected with the control device and the system, the deacidification spraying assembly is arranged in the deacidification tower, the gas supply device and the reaction tank are arranged outside the deacidification tower, and the reaction tank provides alkaline liquid for the deacidification tower through the alkaline liquid input pipeline; a feeding device for providing calcium hydroxide or sodium hydroxide is arranged on the reaction tank, and the reaction tank is connected with the filter press through an output pipeline. The deacidification effect is good, the surface of the deacidified material is clean and dry, and the deacidification efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of deacidification, and in particular relates to a deacidification circulation system and a deacidification process. Background technique [0002] In the prior art, using a deacidification tower to deacidify materials is a deacidification method that is often used at present. The surface of the material is sprayed evenly, the alkaline liquid and the surface of the acidic material are fully contacted and neutralized, and then the alkaline liquid flows down and is transported to the reaction tank by the water pump. After the pH of the alkaline liquid in the reaction tank meets the requirements, It is transported to the deacidification tower again for recycling. The deacidification equipment and deacidification process currently used have the following problems: [0003] 1. The deacidification operation in the deacidification tower has poor effect and low efficiency; [0004] 2. During the deacidification of...
