Example Embodiment

[0018] [Example 1]

[0019] The invention provides a solid adsorbent flow type adsorption device, such as Figure 1-Figure 4 Shown. The device consists of a contact reaction chamber, a gas buffer chamber, a screw conveyor, a gas phase inlet and outlet, a feed hopper, a collection bin, and a collection baffle.

[0020] The left and right ends of the solid adsorbent mobile adsorption device are respectively equipped with a gas inlet system and a gas outlet system; the solid adsorbent 7 enters the reaction chamber 4 through the feed hopper 8 under its own gravity, and the reaction chamber 4 is composed of a mesh plate 6 , Can block the solid adsorbent 7 and make the solid adsorbent 7 fall in the reaction chamber 4. Connected to the reaction chamber 4 is the screw conveyor 3. According to the effective time of solid adsorption 7, the speed of the screw conveyor 3 is preset to make The solid adsorbent that happens to fail or is close to failure is transported by the screw conveyor 3 i...

Example Embodiment

[0024] [Example 2]

[0025] According to the conditions and steps described in Example 1, the solid adsorbent is a special trapping agent for hydrogen sulfide, the process conditions of the reaction chamber are 25 degrees Celsius, 0.1Mpa continuous operation, the mesh plate opening rate is 0.2, and toxic and harmful gases enter The ratio of the mass flow rate of the reaction chamber to the mass flow rate of the solid adsorbent is 1:50. The harmful component in the toxic and harmful gas is hydrogen sulfide with a content of 3000 ppm.

[0026] The harmful component of the treated gas is hydrogen sulfide, with a content of 40 ppm.

Example Embodiment

[0027] [Example 3]

[0028] According to the conditions and steps described in Example 1, the solid adsorbent is an activated carbon / hydrophobic silica gel mixture, the process conditions of the reaction chamber are 100 degrees Celsius, 0.5Mpa continuous operation, the mesh plate opening rate is 0.1, and toxic and harmful gases enter the reaction The ratio of the mass flow rate of the bin to the mass flow rate of the solid adsorbent is 1:100. The harmful component in the toxic and harmful gas is gasoline gas with a content of 10,000 ppm.

[0029] The harmful component of the gas after treatment is gasoline gas with a content of 20 ppm.
