Abstract

The invention discloses a recycling device for harmful gas in tunnel construction and a using method. Exhaust fans are arranged on a trolley, the rear ends of the exhaust fans are provided with a plurality of reaction bottles and gas collecting devices, and therefore the recycling device can absorb the harmful gas in a tunnel and achieve the purpose of recycling industrial raw material gas while overcoming the movement limitation in a tunnel environment. The recycling device has the advantages that the transportation distance of the toxic gas is short, the ventilation time is short, the working efficiency is high, the use cost is low, the recycling device is simple, the operation is convenient, and resources can be recycled.

Description

technical field [0001] The invention belongs to the field of tunnel construction, and in particular relates to a recycling device and a use method for harmful gases in tunnel construction. Background technique [0002] The toxic gas produced in the smoke and dust produced by explosives during the blasting and excavation of tunnels and mine roadways is an important indicator for evaluating their safety levels. The explosion products of explosives mainly include CO, NO 2 , NO, sulfide, dust. CO is easily combined with hemoglobin to form carboxyhemoglobin, which makes hemoglobin lose its ability and function to carry oxygen, causing tissue suffocation and death in severe cases. CO has toxic effects on tissue cells throughout the body, especially the cerebral cortex. At the same time, CO is flammable and is an industrial reducing agent that can be recycled for industrial smelting metals and industrial fuels. [0003] S0 in the atmosphere 2 Concentrations above 0.5ppm have po...
