Description

Porous media material treatment device for triphenyl waste gas

Technical field:

The invention relates to the technical field of waste gas treatment devices, in particular to a device for treating triphenyl waste gas with a porous medium material.

Background technique:

At present, the treatment of triphenyl waste gas usually adopts an activated carbon adsorption device, which passes the triphenyl waste gas into a large-volume treatment tower, and the treatment tower is covered with a columnar granular or mesh-shaped activated carbon layer, which absorbs the triphenyl waste gas. The cost of the device is relatively high, because its activated carbon layer must be thick enough and the volume of the treatment tower must be large enough to achieve a good treatment effect, and the airflow of triphenyl waste gas passes through the activated carbon layer. The resistance is relatively large, and activated carbon Layers are prone to saturation and must be regenerated before they can be used. Another device for the treatment of triphenyl waste gas is to spray the abalone ring packing layer with water, that is, water passes through the gap between the abalone ring packing layer from top to bottom to form a flow path, and the triphenyl waste gas is mixed with water in the flow path from bottom to top. Momentum exchange, mixing harmful substances such as triphenyl fog bead particles in the gas into the water to achieve the treatment effect. However, the headroom ratio of the abalone packing layer is relatively small, so that the airflow of the triphenyl waste gas passes through the abalone packing layer. Treatment effect of benzene waste gas.

Invention content:

The object of the present invention is to provide a triphenyl waste gas treatment device with a porous media material filter as the treatment main body for the deficiencies in the prior art.

In order to achieve the above object, the technical solution adopted by the present invention is: it includes a box body, a sump located at the bottom of the box body, a porous medium material filter group composed of at least one porous medium material filter, and the porous medium material filter group is arranged in the tank. In the body, the top of the porous media material filter is equipped with a water spray pipe 1, and the bottom end of the porous media material filter is inserted into the sump; On both sides of the porous media filter group, the air inlet pipe is installed at the air inlet of the box body, and the exhaust pipe is installed at the air outlet of the box body; A water outlet pipe for drainage is installed at the water outlet; a water spray pipe two is arranged in the box between the air inlet and the porous media filter group; There are three groups of relative spray pipes.

An activated carbon net is arranged in the exhaust pipe.

The periphery of the said water spray pipe one is provided with a water spray pipe cover.

The water spray pipe is connected with a water volume regulating valve for adjusting the water intake.

A fixing groove is installed on the said spray pipe.

The beneficial effects of the present invention are:

A device for treating triphenyl waste gas with porous media materials provided by the present invention includes a box body, a sump located at the bottom of the box body, and a porous media material filter group composed of at least one porous media material filter. The porous media material filter group is arranged in the box In the body, the top of the porous media filter is equipped with a water spray pipe one, and the bottom end of the porous media filter is inserted into the sump, when the water spray pipe one on the top of the porous media filter sprays water into the porous media filter When it is medium, the porous media material filter will form a wet water curtain. When the triphenyl waste gas entering from the air inlet pipe passes through the wet water curtain, most of the harmful substances such as mist beads and solid particles in the triphenyl waste gas will be mixed into the wet water curtain. In the water flow, it is discharged into the water collection tank, so as to achieve the purpose of treating triphenyl waste gas. Compared with the traditional triphenyl waste gas treatment device, the triphenyl waste gas treatment device with this structure has a significant treatment effect. Because the clearance ratio of the porous media material filter is large, it can reduce the resistance of the air flow of the triphenyl waste gas, increase the flow path of the air flow of the triphenyl waste gas, increase the contact area between the water flow and the air flow of the triphenyl waste gas, and the momentum of the two fluids The exchange time becomes longer to improve the treatment effect of triphenyl waste gas.

At the same time, the exhaust pipe is provided with an activated carbon net, which can further absorb the harmful substances of triphenyl waste gas and play an auxiliary treatment role, so that the present invention can achieve a better treatment effect.
