Embodiment 1

[0024] Such as Figure 1-2 As shown, an air desulfurization device based on the tip discharge principle includes a shell 1 filled with an absorbing liquid, the absorbing liquid is NaOH solution, which will react with SO in the gas 2 The following reaction occurs: 2NaOH+SO 2 =Na 2 SO 3 +H 2 O, can remove SO in the gas 2 Fully absorbed, it is worth mentioning that an outlet pipe 19 is fixedly connected to the side wall of the casing 1, and the purified harmless gas will be discharged to the underground construction site through the outlet pipe 19.

[0025] The upper end of the housing 1 is fixedly connected with two symmetrically arranged storage boxes 2 filled with supplementary materials. The storage boxes 2 contain NaOH powder. An air intake cylinder 3 is fixedly connected between the two storage boxes 2. The lower end of the air intake cylinder 3 is provided with a lifting cylinder 4, and the lifting cylinder 4 is threadedly connected with the side wall of the air intak...

Embodiment 2

[0038] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 lies in that the lower end of the intake pipe 8 is fixedly connected with a plurality of horizontal pipes 21 , and the side walls of the lower ends of the plurality of horizontal pipes 21 are provided with a plurality of delivery holes 20 .

[0039] In this embodiment, a plurality of horizontal pipes 21 are laid flat in the absorption liquid in the casing 1, which can effectively increase the contact area between the gas and the absorption liquid, and a plurality of delivery holes 20 are also arranged at the lower end of the horizontal pipe 21, Can increase the contact time of gas and absorption liquid.

Abstract

The invention belongs to the field of underground engineering construction, in particular to an air desulfurization device based on a point discharge principle. The device comprises a shell containingabsorption liquid, the upper end of the shell is fixedly connected with two storage boxes which are symmetrically arranged and contain supplements. An air inlet cylinder is fixedly connected betweenthe two storage boxes; wherein the lower end of the air inlet cylinder is open, a lifting cylinder is arranged in the air inlet cylinder, the lifting cylinder is in threaded connection with the side wall of the air inlet cylinder through a thread on the side wall, a plurality of uniformly distributed conductive needles are fixedly connected to the inner side wall of the lifting cylinder, and a glass layer is fixedly embedded in the side wall of the joint of the air inlet cylinder and the lifting cylinder. According to the device, the storage box is arranged, in the process that the lifting cylinder rotates up and down, when a permanent magnet block moves to the position close to the magnetic block along with the lifting cylinder, the sliding plate in the storage box can slide under the attraction of magnetic force, the multiple discharging holes, the communicating holes and NaOH powder can fall into absorption liquid, the concentration of the absorption liquid is increased, and the absorption effect is guaranteed.

Description

technical field [0001] The invention belongs to the field of underground engineering construction, in particular to an air desulfurization device based on the principle of cutting-edge discharge. Background technique [0002] Underground engineering refers to underground civil engineering that goes deep below the ground to develop and utilize underground space resources. Due to the scarcity of land resources and the effective protection of the ecological environment on the ground, more and more cities have begun to implement underground engineering. [0003] Underground construction, such as coal mining, will produce a lot of harmful gas and dust during the construction process. Sulfur dioxide is a common harmful gas with a large content and great harm. Most of the traditional treatment methods are to use more The gas in the underground construction site is pumped out through the ventilation pump through interconnected pipes to replace the underground gas. However, as the de...
