System and methods for solder flux removal from a gas stream is disclosed. In one aspect, the system includes: a scrubber chamber having a gas inlet and a gas outlet through which the gas stream is introduced into and withdrawn from the scrubber chamber; at least one rinse agent delivery mechanism for introducing a rinse agent into the scrubber chamber for contact with the gas stream, the rinse agent being at a temperature for condensing a first portion of the flux from the gas stream; a condenser portion of the scrubber chamber containing the rinse agent for receiving the gas stream, the rinse agent being at a temperature for condensing a second portion of the flux in the gas stream; and a condensed flux removal apparatus adapted for removal from the scrubber chamber of at least a portion of the rinse agent and the flux which has condensed.

A hybrid humidity control and air purification device and method for hybrid humidity control and air purification. The hybrid device is a single unit capable of humidifying dry environmental air, dehumidifying humid environmental air and removing particulates and contaminants from the air. The device controls the outgoing air to a relative humidity setpoint between 35-50% with negligible particulate matter content. Particulate matter is transferred to water, which may be supplied and flushed by an automatic water pumping system.

The present invention discloses an apparatus for separating and removing dust from exhaust gas, and specifically relates to the field of exhaust gas handling technologies. The apparatus includes a rack, where a dust removal cylinder is disposed on an upper portion of an inner side of the rack, a filter cylinder is detachably connected to a middle portion of a bottom end of the dust removal cylinder, a dust removal mechanism is disposed inside the dust removal cylinder, the dust removal mechanism includes a guide column, an upper end of the guide column is fixedly mounted in a middle portion of an upper end of the rack, several grooves are disposed on an outer side of the guide column, and the groove includes a lower portion.

The facility (1A) includes at least two treatment devices (2) each with an exchange chamber (20) intended to contain a liquid bath in the bottom part and at least one injection line (21). An aeraulic means (4), creates by suction or by blowing, simultaneously and in parallel for each treatment device (2), an incoming gas stream (F) originating from outside the exchange chambers (2) and passes through the discharge opening of the injection line (21) by being introduced into the liquid bath contained in the bottom part of the exchange chamber (20), below the surface (S) of said liquid bath. The exchange chambers (20) communicate hydraulically with one another so that when the aeraulic means (4) are shut down, each exchange chamber (20) is suitable for containing or contains, in the bottom part, an initial volume (V.sub.initial) of liquid, with an initial liquid level (H.sub.initial) that is identical in all the exchange chambers (2).

Methods for sampling the particulates and substances emitted from a test sample when the surface of the sample is ablated. The disclosed sampling chamber and methods avoids the need for clean rooms and other expensive testing apparatus and can be used to test a variety of materials in accordance with standard measurement procedures. Use of the testing chamber and methods assists with safety and risk evaluation in applications such as painting and removal of coatings.

Method and apparatus for cleaning pollution control equipment, such as particulate removal devices, including wet electrostatic precipitators (WESP). The apparatus may include a housing having a chamber, at least one process gas inlet in fluid communication with the chamber, a process gas outlet spaced from the at least one process gas inlet and in fluid communication with the chamber, one or more ionizing electrodes in the housing and one or more collection electrodes or plates in the housing. Sealing liquid is provided and introduced into the chamber in an amount sufficient to submerge the at least one process gas inlet and stop the flow of contaminated gas into the chamber.

A device includes a collection channel, a protection channel, and a tank containing a liquid. The collection channel is configured to direct an airflow containing particles from the outside to the interior of the tank. The airflow passes through the liquid and the protection channel, and is connected to an outlet of the tank. The tank includes a barrier configured to prevent liquid spatters from reaching the outlet and to allow the airflow to pass through the tank to the outlet. The protection channel is connected to a source of suction, is configured to direct the flow from the outlet to the source of suction. The protection channel includes a condenser configured to condense a vapor of the liquid and to direct the generated condensate to the tank.

A liquid filter apparatus for gas/solid separation includes a housing with a filter chamber, a semiconductor process gas inlet, and a process gas outlet. The filter chamber forms a liquid reservoir, and the semiconductor process gas inlet and the process gas outlet are in communication with the filter chamber. The housing further includes a filter liquid inlet and a filter liquid outlet, which are in communication with the liquid reservoir for delivering and removing filter fluid, respectively, to and from the liquid reservoir.

Air cleaning apparatus includes: a tank; a detergent inlet into the tank; a water inlet into the tank; an air inlet into the tank; at least one sparger in fluid communication with the air inlet; a vacuum pump; an air outlet in fluid communication with the vacuum pump; and at least one valve between the air outlet and the vacuum pump and configured to control flow of fluids through the air outlet. The apparatus is configured to conduct a method to pull polluted external air into the tank through the air inlet to the at least one sparger, sparge bubbles of the polluted air from the at least one sparger into a mixture of the water and the nonfoaming detergent in the tank, remove pollutants from the air as it rises through the mixture, extract clean air from the mixture into a cavity in the tank above the mixture and extract the clean air from the cavity through the air outlet to an external environment with the vacuum pump.

A method of producing a cooled dry gas is provided. The method includes exposing an input gas to an aqueous saline solution having a temperature of 20 to 80° C. to produce a first intermediate gas. In addition, the method further includes exposing the first intermediate gas to freshwater having a temperature of greater than −5° C. to less than 20° C. to produce a second intermediate gas. The method also includes cooling the second intermediate gas to a temperature of −40 to −5° C. to produce a cooled gas. The method further includes exposing the cooled gas to a chemical adsorbent to produce a saturated adsorbent and the cooled dry gas.
