Venturi scrubber

Our company has supplied hundreds of Venturi washing (cooling) units to various sulfuric acid equipment manufacturers in Yangzhou.

Venturi scrubber: The Croft-Reynolds jet venturi scrubber is one of the most cost-effective methods for addressing the growing problem of air pollution. It is an effective method for reducing the smoke and unpleasant odors in exhaust gases, cleaning and purifying the air, and recovering valuable products that were otherwise wasted through emissions. The jet Venturi scrubber can also be used as a concentrator, by continuously circulating the absorbent fluid as the driving fluid until the desired concentration is achieved. Due to the absence of moving parts and operation at low speeds, the jet Venturi scrubber requires very little maintenance. Jet Venturi scrubber The jet venturi scrubber uses liquid as the power source for the injector to carry the polluted gases; therefore, it generally does not require a blower to transport the gases that need to be treated. The relatively high gas-liquid ratio and liquid atomization rate, along with the internal open design, enable effective washing of heavily polluted gases. Washers require minimal maintenance, and venturi washers reduce the processing capacity. 　　Its ability to handle various conditions makes the jet Venturi scrubber one of the most flexible designs available, and it is often used as the first stage in multi-stage air pollution control systems. Illustration: The detergent solution is sprayed out from the nozzle, forming a hollow, conical mist stream. The cleaning solution comes into contact with the contaminated gas, enabling extensive mass exchange and capturing the particles in the gas. The mixture is sent to a separator designed by Crell and Reynolds. Packed Tower – The Croft-Reynolds packed tower features a vertical counter-current design, which enables it to absorb various toxic gases very effectively. In addition to its wide use in air pollution control, packed towers can also be employed in various processes as gas-liquid contactors. 99. A washing efficiency of over 99% is common in many gas washing applications. 　　During operation, the gas flows upward through the packing layer, while the washing liquid flows downward along the packing layer under the effect of gravity. The principle of counterflow design ensures optimal mass transfer; in addition, Kroll-Reynolds also provides packed scrubbers with crossflow and co-flow designs. High-energy venturi scrubber The high-energy venturi scrubber is most suitable for capturing particles smaller than 3 microns, and it is also effective against ultra-fine particles. High-energy venturi washer that requires almost no maintenance. When the gas flow rate changes, it is necessary to compensate for the velocity of the gas flowing through the throat in order to maintain the desired washing efficiency; Kroll-Reynolds provides two types of variable throat designs: automatic and manual. The automatically controlled throat design is intended for use in situations where gas flow rates vary significantly and frequent adjustments are required. When changes occur only occasionally, the laryngeal tube design can be controlled manually. Image: Packed washing tower. The packed washing tower utilizes a state-of-the-art packing design to facilitate contact between gas and liquid streams, thereby ensuring that the release of toxic gases is kept at the minimum levels required by regulatory standards. High-energy venturi washer: A high-speed airflow filled with dust is used to atomize the washing liquid. In the separator, the dust-laden liquid within the spiraling airflow is thrown against the outer wall due to centrifugal force; the collected liquid is then sent to the wastewater tank. Multiple systems are used in conjunction to wash and recover hydrogen chloride. A specialty chemical manufacturer was looking for a way to remove hydrogen chloride from exhaust gases before releasing them into the atmosphere. Kroll-Reynolds designed and manufactured a washing system that used two jet venturi scrubbers in series, followed by two packed tower scrubbers. The tight mixing of exhaust gas and washing liquid enabled the jet Venturi scrubber to remove 98% of hydrogen chloride, with the remaining amount being removed by the packed-bed scrubber. The jet Venturi scrubber collected 98% of the hydrogen chloride while producing a marketable hydrochloric acid solution. The filler scrubber is used in a repeated cycle, with a diluted sodium hydroxide solution being applied to further wash the gas stream so that the allowable level of hydrogen chloride emissions is achieved. 　　These devices have been shown to require almost no maintenance, with final emission concentrations of around two parts per million. Very little waste liquid is generated, and the income from selling salts and acids covers the investment in purchasing the system.

It doesn’t matter if the temperature is high or not; just choose the right material

The Chemical Machinery Plant of Nanhua Company is doing well

I’m not sure what project the device you mentioned is used for. The venturi scrubbers produced by our company are primarily used in the wet dust removal process of Shell’s gasification process system. The design temperature is 300–550 °C. Design pressure: 4.6 MPa, processing capacity (including dust and gas): 53.37–155 kg/s.

I’m also looking for a manufacturer that specializes in Venturi designs; what a coincidence

Reply to 1# black0728: A venturi scrubber is also known as a venturi dust collector or venturi scrubbing dust collector. It has a wide range of functions – combining dust removal, desulfurization, and temperature reduction in one. 　　①A Venturi scrubber dust collector is a wet-type dust collector with high dust removal efficiency. A venturi dust collector used in practical applications is a system of equipment that consists of various components such as a venturi scrubber, a demister (or gas-liquid separator), a packed scrubber tower, a sedimentation tank, and a pressure-driven circulation water pump. 　　②The capture mechanism and dust removal process of the venturi scrubber dust collector. The capture of dust by the venturi scrubber dust collector is primarily driven by the impact mechanism, while the diffusion settling mechanism plays a significant role only for very fine dust particles smaller than 0.1 µm. 　　The dust removal process in a Venturi scrubber involves three steps: The dust-laden airflow enters the throat section through the converging tube, where its velocity increases sharply. The washing liquid (usually water) is injected through nozzles evenly distributed around the perimeter of the throat; the droplets are further atomized into even smaller particles by the high-speed airflow, and this process is known as atomization ； In the throat, the gas-liquid phase is thoroughly mixed, resulting in a high efficiency of sedimentation due to the collision between dust particles and water droplets. Upon entering the expansion tube, the air flow slows down and the static pressure gradually increases; the water droplets and dust particles coalesce into larger dust-containing droplets, a process known as coagulation. The gas then enters the demister where gas-liquid separation takes place, achieving dust removal; this process is known as the separation and dust removal process. The atomization process and the condensation process take place inside the venturi tube ； The separation and dust removal process is carried out in a demister or other separation devices such as a packed scrubber tower. 　　The purified gas is discharged from the top of the demister, while the dust-containing wastewater is sent to the sedimentation tank through the conical bottom of the demister. 　　③Features of the venturi washing dust collector: The main features of the venturi washing dust collector are: a. Simple and compact structure, small size, low space requirement, and low cost ； b. It is used not only for cooling high-temperature flue gases and purifying high-temperature, high-humidity, and flammable gases, but also for purifying gases containing micron and sub-micron dusts, as well as toxic and harmful gases that can be absorbed by washing liquids such as sulfur dioxide, hydrogen chloride, and sulfuric acid. 　 Introduction to the venturi scrubber produced by Yangzhou Haotian Environmental Protection Equipment Co., Ltd.: The jet-type venturi scrubber developed by Yangzhou Haotian Environmental Protection Equipment Co., Ltd. is one of the most cost-effective methods for addressing the growing problem of air pollution.
