Embodiment 1

[0026] Such as figure 1 As shown, an air purifier for underground engineering construction includes a box body 1, the box body 1 is made of thermal insulation material, and a fan 2 is fixedly installed at the lower end of the box body 1. The model of the fan 2 is HG-2200W, and the fan 2 passes through The one-way air inlet pipe 3 communicates with the box body 1, and the one-way air inlet pipe 3 only allows the gas to enter the box body 1 from the fan 2. It is worth mentioning that the upper end of the one-way air inlet pipe 3 runs through the box body 1 and extends to the box body 1, the upper end of the one-way air intake pipe 3 is fixedly connected with a branch pipe 11, and the side wall of the branch pipe 11 is provided with a plurality of through holes 12 arranged in an equidistant array.

[0027] In this embodiment, the upper end of the box body 1 is fixedly connected with an air outlet pipe 4, and the side wall of the air outlet pipe 4 is fixedly installed with a therm...

Embodiment 2

[0032] Such as Figure 2-3As shown, the difference between this embodiment and Embodiment 1 is that a housing 15 is rotatably connected to the inner wall of the box body 1, and a fan 16 is fixedly connected coaxially above the housing 15, and the fan 16 is arranged on the air outlet pipe 4. Inside, the air flow in the air outlet pipe 4 is relatively concentrated, and the fan 16 is subjected to a larger torque, so the speed is faster. The inner wall of the housing 15 is fixedly connected with an annular baffle 17, and the annular baffle 17 is provided with a plurality of drainage holes. , the annular baffle plate 17 divides the inside of the housing 15 into a water absorption chamber 18 and a drainage chamber 19, the water absorption chamber 18 is filled with water absorption cotton 20, and the upper top surface and the lower bottom surface of the water absorption chamber 18 are provided with a connection with the box body 1 The air holes and the lower end of the drain chamber ...

Abstract

The invention belongs to the field of gas purification devices, in particular to an air purifier for underground engineering construction. The air purifier comprises a box, wherein a fan is fixedly mounted at the lower end of the box and communicated with the box through a one-way gas inlet pipe; the upper end of the box is fixedly communicated with a gas outlet pipe; a thermoelectric power generation plate is fixedly mounted on and runs through the side wall of the gas outlet pipe; the box is filled with an alkaline solution; electrolysis chambers communicated with the interior of the box arearranged on two side walls of the box; the upper ends of the electrolysis chambers are fixedly communicated with gas exhaust pipes; and the upper ends of the gas exhaust pipes are higher than the level of the alkaline solution. According to the air purifier, acidic gases in air can be absorbed through the alkaline solution for purifying the air, so as to ensure the health and safety of underground workers; and the water generated by a reaction is electrolyzed through the thermoelectric power generation plate, so as to prevent the problem that the purification effect is poor because the alkaline solution is diluted.

Description

technical field [0001] The invention belongs to the field of gas purification equipment, in particular to an air purifier for underground engineering construction. Background technique [0002] Underground engineering refers to the underground civil engineering that goes deep below the ground to develop and utilize underground space resources. It includes underground houses and underground structures, underground railways, highway tunnels, underwater tunnels, underground common trenches, and underground passages for street crossings. During the construction of underground engineering, construction operations such as drilling, blasting, and slag loading will produce a large amount of dust particles and acid gases (such as SO 2 ), if the air circulation is not smooth, it will aggravate the insufficient fuel combustion of the machine due to lack of oxygen, and the acid gas content in the exhaust gas will increase, thereby reducing the power of the machine, damaging the health o...
