This invention discloses a low-temperature dry dust removal device for phosphorus furnace gas, comprising: two sets of series-connected metal felt filter screens, filter screen electric heaters, a backflushing system, a dust collection funnel, a spiral dust collector, and a fan. The outlet pipe of the yellow phosphorus furnace gas is connected to the inlet of the series-connected metal felt filter screens. Each metal felt filter screen is equipped with an electric heater. The backflushing system achieves dust removal by adjusting the valve switch to reverse the gas flow. The filter cake outlet of the metal felt filter screen is connected to the inlet of the dust collection funnel. The outlet of the metal felt filter screen is connected to the inlet of the fan. The dust outlet at the bottom front side of the metal felt filter screen and the dust collection funnel are sealed and connected to the dust inlet of the closed spiral dust collector. The outlet of the fan is the exhaust port of the device. This device can solve the problem of yellow phosphorus furnace gas condensation clogging and corrosion of equipment, achieve low-temperature and high-efficiency dust removal of yellow phosphorus furnace gas, and improve filtration efficiency and phosphorus yield.

The invention relates to the technical field of paint mist flocculants, in particular to a paint mist flocculant for water-based paint and a preparation method thereof, functional groups such as amino and hydroxyl in modified chitosan can more effectively interact with paint mist particles in the water-based paint after being specifically treated, so that the agglomeration and sedimentation of the paint mist particles are promoted, and the water-based paint mist flocculant is prepared. The enhanced flocculation effect is beneficial to reduction of suspended matters and turbidity in the wastewater and improvement of wastewater treatment efficiency and quality; moreover, the modified chitosan is used as a part of a flocculating agent, so that the removal process of paint mist particles in the water-based paint wastewater can be accelerated, and the wastewater treatment time is shortened; secondly, aldehyde groups in the modified carboxymethyl cellulose and an introduced melamine structure can more effectively interact with paint mist particles in the water-based paint, and agglomeration and sedimentation of the paint mist particles are promoted in modes of chemical adsorption, physical entanglement and the like.
