Pressure type atomization spray head for tunnel construction

Abstract

The invention discloses a pressure type atomization spray head for tunnel construction. The pressure type atomization spray head comprises a shell and a nozzle. A liquid inlet channel is formed at theend, away from the nozzle, of the shell. The end, in the shell, of the liquid inlet channel communicates with a magnetization chamber. The magnetization chamber is of a spiral columnar structure, andthe end, away from the liquid inlet channel, of the magnetization chamber serves as the center line part of the shell and is provided with a liquid outlet channel in a communicating manner. A permanent magnet is fixedly connected in the magnetization chamber. A mixing chamber is arranged at the end, away from the magnetization chamber, of the liquid outlet channel in a communicating manner. The mixing chamber communicates with the nozzle. A reversing structure is arranged at the joint of the liquid outlet channel and the mixing chamber. The pressure type atomization spray head has the advantages that the magnetization chamber and the permanent magnet are arranged in the nozzle to obtain magnetization water, and therefore the adsorption effect of water mist sprayed out by the nozzle to dust in air is increased; and meanwhile, a connecting port is reversely flushed by a reversing pipe, the situation that pressure relief is influenced by blocking is avoided, the height of water mist spray out by the nozzle is guaranteed, and the dust fall effect is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a pressure-type atomizing nozzle for tunnel construction. Background technique [0002] The dust problem has always plagued many industries that are in direct contact with dust. It not only affects a large number of people, but also seriously harms human health, the most serious of which is pneumoconiosis. In tunnel construction, the problem of dust is always serious, mainly It comes from the dust raised by excavation, blasting and mechanical operations in the cave. [0003] In the prior art, the method of removing dust during tunnel construction generally adopts wet dust removal, that is, water mist is produced through nozzles, water flow and air flow to reduce the dust content in the air. Among them, the pressure nozzle is an important component of wet dust removal equipment. The existing spray dust reduction has indeed played a certain role, but the dust reduction...
