Description

Technical Field

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

[0002] In the face of the implementation of ultra-low emission standards, although the nitrogen oxide content in blast furnace gas is low, it still needs to undergo denitrification treatment. At the same time, blast furnace gas also contains harmful substances such as COS, HCl, and NH4Cl, which require dechlorination and COS hydrolysis catalytic conversion treatment. Therefore, multi-stage catalytic treatment of blast furnace gas is required. Most current catalytic processors are only suitable for single-stage catalytic use of gas and are not suitable for multi-stage separated catalytic treatment.

[0003] In summary, there is a need for an exhaust gas catalytic converter. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an exhaust gas catalytic processor that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A waste gas catalytic converter includes a reactor body with chambers inside. The chambers are connected by through-slots on the inner wall of the reactor body. An air inlet pipe is connected to the left side of the reactor body. A support frame is provided on the inner wall of the chambers, and an opening slot is provided on the support frame. A catalytic box is provided above the support frame, and a sealing cover is connected to the upper end of the catalytic box. The sealing cover is in sealing contact with the upper end of the reactor body.

[0007] Furthermore, a hydraulic telescopic rod is connected below the sealing cover, and the hydraulic telescopic rod is located on the front and rear sides of the reactor body.

[0008] Furthermore, the catalyst box is provided with three layers, and the catalyst box is filled with a first catalyst layer, a second catalyst layer and a third catalyst layer from left to right. The bottom side of the catalyst box and the side near the through slot and the gas outlet are provided with through holes.

[0009] Furthermore, the reactor body includes an outer shell, which is connected to the air outlet on the right side of the reactor body. An activated carbon box extends through the upper end of the outer shell, and activated carbon filler is placed inside the activated carbon box.

[0010] Furthermore, the reactor body also includes a first bolt, which is disposed through the top of the activated carbon box, with one end of the first bolt threaded onto the outer shell.

[0011] Furthermore, the sealing cover includes a sealing plate, on which the sealing cover is provided, and a second bolt is provided through the sealing plate, one end of which is threaded to the sealing cover, and the sealing plate and the catalyst box correspond one-to-one.

[0012] This invention provides an exhaust gas catalytic converter. Compared with the prior art, it has the following advantages:

[0013] Firstly, chambers are formed within the reactor body, each containing a corresponding catalyst box. From left to right, the catalyst boxes are filled with a first catalyst layer, a second catalyst layer, and a third catalyst layer. The chambers are connected by through-holes. Exhaust gas enters the reactor body through an inlet pipe and undergoes denitrification, dechlorination, and hydrolysis catalytic conversion treatment sequentially through the first, second, and third catalyst layers. This multi-stage catalytic treatment of the exhaust gas further enhances its effectiveness. The treated exhaust gas is then filtered through activated carbon packing for adsorption, further improving the treatment efficiency. The catalyst box can be pushed out of the reactor body by a hydraulic telescopic rod to replace the catalyst. Attached Figure Description
