Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas processor for deep treatment. Background Technology

[0002] The exhaust gas processed by the exhaust gas processor contains various particulate matter, oil mist, water vapor, volatile organic compounds, aerosols, heavy metals, and odorous gases containing sulfur and nitrogen. Existing exhaust gas processors can generally remove large particulate matter and oil mist through dust removal and washing, but they are not very effective for some fine particulate matter, odorous gases, and some low-concentration or difficult-to-degrade organic matter. As a result, a lot of harmful substances remain in the exhaust gas after the exhaust gas processor is processed. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a waste gas processor for deep treatment.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A waste gas processor for deep treatment includes a treatment host, characterized in that: an activated carbon box is installed at the exhaust port of the treatment host, and columnar activated carbon with an iodine value of 200-800 is arranged in the activated carbon box.

[0006] The length of the columnar activated carbon is 6mm-10mm.

[0007] The columnar activated carbon inside the activated carbon box forms an activated carbon layer with a thickness of 6cm-10cm.

[0008] Stainless steel screens are installed at the inlet and outlet of the activated carbon box.

[0009] The stainless steel screen has a mesh size of 6-15.

[0010] The stainless steel screen has a wire diameter of 0.2mm-0.5mm.

[0011] The stainless steel screen on the outlet side of the activated carbon box is fixed with screen pressure strips around its perimeter. If the screen pressure strips around the perimeter are not stable enough, a straight or cross-shaped screen pressure strip can be arranged in the middle of the stainless steel screen.

[0012] The stainless steel screen on the inlet side of the activated carbon box is placed on the annular step plate at the inlet of the activated carbon box.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention adds an activated carbon box to the rear of the main unit's exhaust vent, filled with columnar activated carbon with an iodine value of 200-800 and a length of 6mm-10mm. This allows for deep adsorption of residual pollutants and efficient removal of VOCs. The porous structure of activated carbon can adsorb volatile organic compounds (such as benzene, toluene, and formaldehyde), especially effective for low concentrations or recalcitrant organic compounds. It also captures fine particles, adsorbing aerosols and heavy metals (such as mercury vapor), compensating for deficiencies in pretreatment (such as dust removal and washing). Furthermore, it effectively eliminates odors, as activated carbon has a strong adsorption capacity for sulfur- and nitrogen-containing malodorous gases (such as hydrogen sulfide and ammonia), significantly improving the surrounding air quality.

[0018] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0019] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0020] like Figure 1-2 As shown: A waste gas processor for deep treatment includes a treatment host 1, an activated carbon box 2 installed at the exhaust port of the treatment host 1, and columnar activated carbon 3 with an iodine value of 200-800 arranged in the activated carbon box 2. The columnar activated carbon 3 has a length of 6mm-10mm and can form an activated carbon layer with a thickness of 6cm-10cm. Different specifications of activated carbon can be replaced according to the actual effect.

[0021] Specifically, the inlet and outlet of the activated carbon box 2 are equipped with stainless steel screens 4 with a mesh size of 6-15 and a wire diameter of 0.2mm-0.5mm. The stainless steel screen 4 on the inlet side of the activated carbon box 2 is placed on the annular step plate at the inlet of the activated carbon box 2, and the stainless steel screen 4 on the outlet side of the activated carbon box 2 is fixed with screen pressure strips 5 around its perimeter. Example

[0022] like Figure 1-2 The exhaust gas processor shown includes a conventional treatment host 1. An activated carbon box 2 is installed at the exhaust port of the treatment host 1. The activated carbon box 2 is used to fill with activated carbon, which is used to adsorb harmful substances and odors. This invention uses columnar activated carbon 3 with an iodine value of 200. The columnar activated carbon 3 is 6mm long and can form an activated carbon layer with a thickness of 6cm. To allow the activated carbon box 2 to be filled with activated carbon, an annular stepped plate is provided at the inlet of the activated carbon box 2. A stainless steel screen 4 with a wire diameter of 0.5mm and a mesh count of 6 is placed on the annular stepped plate. The stainless steel screen 4 at the inlet is used to hold the activated carbon. A stainless steel screen 4 with a mesh count of 6 and a wire diameter of 0.5mm is provided at the outlet of the activated carbon box 2. The stainless steel screen 4 at the outlet is used to cover the activated carbon to prevent it from being blown away by the exhaust air. Furthermore, the stainless steel screen 4 at the outlet is pressed down by a screen clamping strip 5. The activated carbon box 2 can be pre-installed and simply fixed to the exhaust port of the main treatment unit 1 with screws during use. It can be disassembled at any time for replacement. The exhaust gas is first treated by the main treatment unit 1, and then further purified by the activated carbon box 2 to eliminate residual harmful substances and odors in the exhaust gas.

[0023] This invention adds an activated carbon box 2 to the rear of the exhaust vent of the main treatment unit 1, filled with columnar activated carbon 3 with an iodine value of 200-800 and a length of 6mm-10mm. This allows for deep adsorption of residual pollutants and efficient removal of VOCs. The porous structure of activated carbon can adsorb volatile organic compounds (such as benzene, toluene, formaldehyde, etc.), especially effective for low concentrations or recalcitrant organic compounds. It can also capture fine particles, adsorbing aerosols and heavy metals (such as mercury vapor), compensating for the deficiencies of previous treatments (such as dust removal and washing). Furthermore, it effectively eliminates odors, as activated carbon has a strong adsorption capacity for malodorous gases containing sulfur and nitrogen (such as hydrogen sulfide and ammonia), significantly improving the surrounding air quality.
