PZGO LLC offers individual calculation, design, manufacturing and local installation of reliable, inexpensive, effective and compact Venturi scrubbers.
Despite the fact that industrial Venturi dust collectors are mainly aimed at trapping mechanical pollutants, their use is not limited to this. Loading an acidic, alkaline, or other chemical solution into absorbent reservoir makes it possible to perform bi-phase (gas-solid) air or gas cleaning.
The simplicity of the design and the absence of moving parts make these dedusters a rational choice for a variety of air-cleaning procedures. The high flow rate provided by the Venturi cone (up to several hundred meters per second) allows neutralizing / utilizing sticky and cementing dusts, suspensions and emulsions with high efficiency.
In addition, Venturi systems are characterized by low pressure drop, and, like other wet-type scrubbers, are capable of processing high-temperature air flows, cooling and moistening the gaseous medium.
As is clear from the name of the apparatus, the main functional element of the scrubber is the so-called Venturi tube. This pipe consists of two cones, whose narrow necks are directed towards each other.
By the way, sometimes, in the design of gas-cleaning equipment, expanding pipes are implemented, whose principle of operation is reverse to the Venturi principle. This is done in those cases when the gas stream must not be accelerated, but, alternatively, slowed down.
The principle of the tube, (and the scrubber proper), is based on the Venturi effect. This principle, stemming from the Bernoulli Effect, describes the dependence of the velocity of the gas medium on the diameter of the pipe. That is, the smaller the diameter of the pipe in which the flow moves, the higher its speed, and vice versa.

Please note one important feature. Due to the high flow velocities, the working section of the Venturi tube is subjected to mechanical wear, especially if there is a treatment of gas or air flows containing abrasive dusts.
The Venturi dust arrester shows outstanding performance in capturing flue gas (SOx, NOx, HCl), ash and soot.
This leads to a slight increase in the cost of construction, but dramatically simplifies the maintenance and repair of turbulent / coagulation-type wet dust collectors.
As for technical characteristics, dust collectors of this type (produced within the facilities of PZGO LLC) have the following specifications:
If gases (or air) containing dust along with strong chemical pollutants are treated, it is recommended to install Venturi systems as preliminary facilities. For integrated pollution control it is reasonable to use chemical absorbers or fluidized bed scrubbers as the main gas cleaning equipment.
Please note that this drawing is a reference. We develop each air purifier with a subtle consideration for the characteristics of each industrial site, so the final design and components’ relative positions of the device may vary slightly
