Efficient Venturi Wet Dust Collector

technical field

The utility model relates to the technical field of dust collectors, in particular to a high-efficiency Venturi wet dust collector.

Background technique

Venturi dust collector is a new type of dust collector. It installs a Venturi flow channel on the flue gas inlet pipe of the water film dust collector, sprays water at the venturi throat, and condenses into larger particles due to water absorption. Currently used Venturi dust collectors, the Venturi flow channel is usually cut into the cylinder, and some are set after passing through the filter filter arranged in the cylinder horizontally. The disadvantages of the currently used Venturi dust collector are: the standard discharge of purified air is not very reliable, the structure is complicated during processing, the choice of materials is limited, and the anti-corrosion treatment of parts is difficult to be uniform, which affects the overall service life, and the installation and maintenance are more cumbersome.

Utility model content

The technical problem to be solved by the utility model is to provide a high-efficiency Venturi wet dust collector which can prolong the contact time between smoke and water mist and has a simple structure.

In order to solve the above problems, the technical solution adopted by the utility model is: a high-efficiency Venturi wet dust collector, including a box body, the upper part of the box body is provided with a fan and a purified gas outlet, the lower part of the box body is a water tank, and the bottom of the water tank A drain valve is provided, and a Venturi flow channel is provided above the water tank. The Venturi flow channel is inserted horizontally, one end of which is located outside the tank, and a spray head is arranged in it, and the other end of which opens downward. The Venturi flow channel and At least one layer of filter is arranged between the fans.

As a preferred solution, a circulation pump and an automatic water supply device are arranged outside the box, one end of the circulation pump is connected to the water tank, and the other end of the circulation pump is connected to the spray head.

As a preferred solution, two layers of filters are arranged between the Venturi channel and the fan, and the two layers of filters are arranged parallel to each other.

The beneficial effects of the utility model are: the above-mentioned high-efficiency Venturi wet dust collector, its Venturi channel adopts a horizontal design, and is located below the filter, thereby avoiding the installation between the Venturi channel and the filter The interference during the time not only expands the effective area of the filter, but also simplifies the structure during processing, making the installation more convenient. The flue gas and water mist can fully contact in the horizontally arranged Venturi flow channel, and use inertia to spray to the water surface, thereby improving the effect of dust settlement. It is the safest system for dealing with flammable and explosive media; the exhaust air meets the "Purification Air Standard" , in line with the instructions issued by professional associations; high sedimentation and separation efficiency; modular assembly, parts spray treatment, or stainless steel; small footprint, simple and safe operation and maintenance, regular sewage valve can be set to automatic periodic sewage according to customer needs. It is widely used in dry and wet mixing processing, grinding and polishing processing, processing of combustion and explosive media, smoke and sparks, viscous fiber dust and other fields.

Detailed ways

The following is a further detailed description of the high-efficiency Venturi wet dust collector described in the present invention through specific examples.

As shown in Figure 1 and Figure 2, the high-efficiency Venturi wet dust collector includes a box body 1, the upper part of the box body 1 is provided with a fan 2 and a purified gas outlet 3, the lower part of the box body 1 is a water tank 4, and the water tank 4 A drain valve 5 is provided at the bottom of the water tank 4, and a Venturi flow channel 6 is provided above the water tank 4. The Venturi flow channel 6 is inserted transversely, one end of which is located outside the box body 1, and a spray head 7 is arranged in it, and the other end is open. Downward, at least one layer of filter 8 is arranged between the Venturi channel 6 and the fan 2 . In this embodiment, two layers of fritters 8 are arranged between the Venturi channel 6 and the fan 2 , and the two layers of fritters 8 are arranged parallel to each other.

As a preferred solution, a circulation pump 9 and an automatic water supply device 10 are provided outside the box 1 , one end of the circulation pump 9 is connected to the water tank 4 , and the other end of the circulation pump 9 is connected to the spray head 7 . Through the automatic water supply device 10, the water storage capacity inside the box body 1 is ensured. Through the circulation pump 9, water circulation is realized.

The working principle of the utility model is: under the action of the fan 2, there is a negative pressure inside the box body 1, and the dust and waste gas located at the Venturi channel 6 are sucked into the inside of the box, and are captured by the water mist sprayed out by the sprayer to form Fall into the water tank 4 behind the big droplet, and the small droplet (mist) is infiltrated and caught by the demister to form the droplet and falls into the water tank 4 equally, and the circulation sprays, go round and begin again.

In the above-mentioned high-efficiency Venturi wet dust collector, the Venturi flow channel 6 adopts a horizontal design and is located below the filter 8, thereby avoiding the interference between the Venturi flow channel 6 and the filter 8 during installation, It not only enlarges the effective area of the filter 8, but also simplifies the structure during processing, making the installation more convenient. Smoke and water mist can fully contact in the horizontally arranged Venturi flow channel 6, and use inertia to spray to the water surface, thereby improving the effect of dust settlement, and it is the safest system for dealing with flammable and explosive media; "Standard", in line with the instructions issued by professional associations; high sedimentation and separation efficiency; modular assembly, parts spray treatment, can also be made of stainless steel; small footprint, simple and safe operation and maintenance, regular sewage valve 5 can be set to automatic according to customer needs Sewage regularly.
