Jet Venturi Fume Scrubber

Principle Of Operation

The AirPoll Jet Venturi is a device that is specifically made to scrub large quantities With the use of "Vena Contracta," of gases. Around the vent throat, where the gas is moving at a very high velocity and is being separated, there is a quick expansion and contraction that is known as vena contracta. The motive fluid, typically water, emerges from the nozzle in the shape of a hollow cone spray, generating a draught that pulls gases and vapours into the moving stream, where they are continually cleaned. The fume/gas cleaning Jet Venturi scrubber is quite effective.

Jet Venturi Fume Scrubbers, shown in Fig. 1.1, are highly good in removing harmful gases, particles, odours, fumes, and dusts from gas streams. The high velocity spray of scrubbing liquid impactionally removes particulate particles. By chemical reaction between the gases and cleaning liquid as well as absorption, gases and odours are removed. These scrubbers, when correctly suited to the application, are more able to withstand the frequently encountered high temperatures, significant pollutant loads, and corrosive conditions.

Vent Gas Scrubber System

Principle Of Operation

The Fig. 2.1 Vent Gas Scrubber System is a compact, light-weight and easy-to-install unit designed for economical and effective control of pollution from low volume sources. Vent Gas Scrubber System is comprised of a Fig. 2.2 Scrubber combined with Liquid Gas Separator. Both are available from stock. Use of the combined Fig. 2.1 Vent Gas Scrubber and Gas Separator is recommended where it is undesirable to send the entrained gas down the drain with the scrubbing liquid. No pressure drop is encountered when using this Liquid Gas Separator, therefore, no effect on scrubber capacity is seen.

The Fig. 2.2 Liquid Gas Separator is a device to separate the entrained gas and liquid discharged from a Fig. 2.2 Vent Gas Scrubber. It operates on the gravity principle with the liquid directed to the bottom to run out a drain opening while the gas must make a 180 degree change of direction to exit through a top outlet. The unit is sized to allow low gas velocity so that gravity separation can be achieved.

High Energy Venturi Scrubber System

Principle Of Operation

Fig. 3.1 High Energy Venturi Scrubber Systems are designed to remove fine micron and submicron particulate from industrial and commercial effluent gases. High Energy Venturi Scrubber System is a wet scrubbing system that combines a High Energy Venturi Scrubber with a Cyclonic Separator. These scrubbers are effective in the removal of dusts, fumes, vapors, and mists; as well as a variety of other air pollutants. Removal efficiency is related to the characteristics of the contaminant and the pressure drop induced across the throat section of the venturi.

The Cyclonic Separator operates on the inertial effect which makes the heavier liquid and solid materials travel in a path around the walls of the separator and the gas or vapor takes a path toward the center. By suitably locating the exits, the separated streams are collected for further processing.

Packed Tower Gas Scrubber

Principle Of Operation

Packed Tower Gas Scrubbers are low-energy gas scrubbers. They are used for gas absorption, cooling, and recovery. Because of their high scrubbing efficiency and low power consumption, they are used in many industries for a broad range of applications. Scrubbers of this type perform best when gases to be handled are free of particles, since these tend to clog the packing.

Gas enters the tower through the inlet near the bottom and passes through the support plate into the packed bed, counter current to the flow of the scrubbing liquid, contaminants are removed. After passing through the packed bed, the cleaned gas passes through a mist eliminator section near the top of the tower. Here, any entrained liquid is removed before the clean air is discharged through the outlet.

Packaged Scrubber

Principle Of Operation

Packaged Scrubber System is a completely “packaged”, movable gas scrubber separator system that is especially designed for use in pilot plants, laboratories, or temporary locations in full size processing plants. Packaged Scrubber System uses water or other liquid to clean large quantities of objectionable gases that are inherent in most laboratories or processing applications.

Packaged Scrubber System can achieve contaminant removal efficiencies as high as 99.99% in many applications.This package typically consists of a Ejector Venturi Gas Scrubber and Separator with storage mounted on a steel baseplate.

WET Electrostatic Precipitators

Electrostatic Precipitator Prinicipal

An electrostatic precipitator is air pollution control device used to separate solid particulate matter from a contaminated air stream. Contaminated air flows into an ESP chamber and is ionized by electron emitting electrodes; also known as the corona chamber. The suspended particles are charged by the electron field and migrate to a collection plate. Accumulate particulate matter is removed from the collection plates at periodic intervals by rapping or hitting the plates with rappers (mallets type hammers). Heavy particles fall to the base of the ESP where hoppers hold the removed particles for disposal.

Electrostatic precipitators are used to separate small particles, 1 micron or smaller, from gas streams. This process is also used in desalters to separate salts and sediment from crude oil feeds.
