METHODS OF AUTOMATED GARBAGE CHUTE AIR EVACUATION TO IMPROVE AIR QUALITY
20220370676 · 2022-11-24 ·

This description relates to waste disposal garbage chutes and more particularly to automated air quality management in and around the disposal chute and collection rooms where garbage chutes are present utilizing automated air quality sensing hardware and evacuation devices to provide a clean, sanitary waste room environment. A system according to the present invention includes a 3 step design using an air sensor to determine air cleaning cycle, and an air intake port with specular reflective surfaces in the inside to provide a reflective element to reflect UV light into the airborne particulates thereby killing 99% of the bacteria and fungi before entering an electrified gravity fed fluid filament air filter which collects the dead bacteria and fungi and settles in a collection reservoir. The fluid in the reservoir is then further filtered to clean the fluid for reuse in the automated air cleaning system.

Apparatus and method for wet cleaning a gas stream

An apparatus and method for wet cleaning a gas stream has a housing with a gas inlet and a gas outlet, wherein, in the housing, there is at least a first washing segment that serves to clean the gas stream with a washing liquid and that is arranged in the flow path of the gas stream. Inside the housing of the apparatus, there is at least one fan that regulates air pressure along the flow path of the gas stream. A bypass channel for bypassing the flow path through the at least one washing segment as well as a regulator that is arranged in the bypass and that serves to discharge the gas stream being conveyed via the bypass channel are arranged inside the housing.

Systems and methods for dry fog inlet particle separator

An inlet particle separator system for a gas turbine engine includes a separator manifold. The separator manifold includes an inlet upstream from an outlet. The inlet is to receive an incoming airflow, and the outlet is to be fluidly coupled to an inlet of the gas turbine engine. The inlet particle separator system includes at least one dry fog nozzle coupled proximate the inlet so as to face at least partially away from the inlet. The dry fog nozzle is external to the separator manifold, and the dry fog nozzle is to direct a spray of dry fog in a direction transverse to the incoming airflow to agglomerate with fine particles in the incoming airflow to form agglomerated particles. The inlet particle separator system includes a scavenging system coupled to the separator manifold downstream from the inlet, and the scavenging system removes the agglomerated particles from the separator manifold.

Wet scrubber apparatus

A wet scrubber apparatus has a housing with access doors and guides that allow for the installation of self-contained baffle modules. Selected baffle modules can to be inserted, exchanged, removed or left blank (no baffles) within the wet scrubber housing, depending on the desired process. The wet scrubber allows for variable performance and feature-enhancing for a target efficiency and effectiveness. The wet scrubber can incorporate a pump and pipe manifold “fluidizer” design that can spray water or fluid up onto the modules during operation of the wet scrubber to keep collected material off the baffles. Water can be sprayed throughout the modules onto the baffles during operation, or when the scrubber is offline, isolated from the gas to be scrubbed, during a cleaning operation. This water or fluid can come from an outside source or can be piped and valved to recirculate existing scrub water or fluid.
