Three-fluid mist spraying dust suppression system and method

Abstract

The invention discloses a three-fluid mist spraying dust suppression system and method. The system is characterized in that a first valve and a first flow meter which are installed on a water pipe; a second valve and a second flow meter are installed on a first chemical pipe; the water pipe and the first chemical pipe are connected with a chemical-water mixing apparatus, water flowing into the medicine-water mixing apparatus is mixed with chemical to form a mixture, and the mixture flows out by virtue of a second chemical pipe; a third valve and a third flow meter are installed on the second chemical pipe; a fourth valve and a fourth flow meter are installed on an air pipe; the second chemical pipe and the air pipe are connected with an atomizing spray head, the atomizing spray head utilizes air to crush the mixture into mist particles, and the mist particles are sprayed out; and a dry mist dust suppression main machine receives signals of various flow meters and controls various valves and the atomizing spray head. By adopting the system and method, the research bottleneck of the dust suppression effect in the prior art is broken through, the dust suppression effect is further improved, and the dust suppression speed is increased.

Description

technical field [0001] The invention relates to the technical field of dust suppression in thermal power plants, in particular to a three-fluid spray dust suppression system and method. Background technique [0002] Dust suppression systems in the prior art mostly use dry fog dust suppression systems or agents with dust suppression effects for dust suppression. The dust suppression system generates dry fog particles through special nozzles, and achieves the purpose of dust suppression by increasing the contact area with the dust. The agent with dust suppression effect is composed of new multifunctional polymers. The degree of cross-linking between polymer molecules will form a network structure, and there are various ionic groups between the molecules, which can generate strong affinity with ions. The action mechanism of the agent is to capture, absorb, and agglomerate dust particles, and lock them in the network structure, so as to play the role of wetting, bonding, conde...

Problems solved by technology

[0003] However, both the dry fog dust suppression system and the agent with dust suppression effect have limited dust suppression effects, and cannot quickly suppress high-concentration dust.
