Description

Technical Field

[0001] This utility model relates to the technical field of rotary kilns, and in particular to a rotary kiln exhaust gas treatment device. Background Technology

[0002] A rotary kiln is a cylindrical piece of equipment, usually placed horizontally or slightly inclined. It uses rotational motion to perform heat treatment and chemical reactions on materials. Depending on the materials processed, rotary kilns can be classified into various types, such as cement kilns, metallurgical and chemical kilns, and lime kilns. Rotary kilns generate a large amount of waste gas during industrial production. This waste gas mainly contains harmful substances such as dust, sulfur dioxide, and nitrogen oxides. If this waste gas is discharged directly without treatment, it will cause serious pollution to the atmospheric environment and even threaten human health. Therefore, rotary kilns typically require the use of waste gas treatment equipment.

[0003] Currently, in the process of treating the waste gas generated by the rotary kiln through the waste gas treatment device, for high concentrations of organic waste gas, the activated carbon adsorption capacity may increase significantly in a short period of time, causing the activated carbon to generate a large amount of heat, which may lead to spontaneous combustion and pose a safety hazard to relevant personnel. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a rotary kiln exhaust gas treatment device. During the process of treating the exhaust gas generated by the rotary kiln through the exhaust gas treatment device, air can be introduced to dilute the high concentration of organic waste gas, thereby minimizing the possibility of spontaneous combustion of activated carbon due to a large increase in the amount of activated carbon adsorbed in a short period of time.

[0006] To achieve the above objectives, the first aspect of this utility model provides a rotary kiln exhaust gas treatment device, comprising: a body, an inlet pipe, and a dilution mechanism, wherein the inlet pipe is disposed on the side wall of the body; the dilution mechanism includes multiple mounting columns, multiple one-way valves, a mounting frame, and a fan, wherein multiple mounting holes are equidistantly opened on the outer wall of the inlet pipe; the multiple mounting columns are respectively installed in corresponding mounting holes; the multiple one-way valves are respectively installed in corresponding mounting columns; the mounting frame is connected to the inner wall of the inlet pipe; and the fan is installed in the mounting frame.

[0007] In addition, the rotary kiln exhaust gas treatment device proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, an exhaust pipe is provided on the side wall opposite the air inlet pipe of the device.

[0009] Specifically, symmetrical support legs are arranged on the bottom wall of the vessel.

[0010] Specifically, a gas monitoring device is installed through the outer wall of the vent pipe.

[0011] Specifically, a dustproof mesh is installed on the inner wall of the air intake pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The rotary kiln exhaust gas treatment device of the present invention can introduce air to dilute the high concentration of organic waste gas during the process of treating the exhaust gas generated by the rotary kiln, thereby avoiding the situation where the activated carbon generates a large amount of heat and spontaneously combusts due to a large increase in the amount of activated carbon adsorbed in a short period of time.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The rotary kiln exhaust gas treatment device of this utility model is described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the rotary kiln exhaust gas treatment device of this utility model embodiment includes: a body 1, an air inlet pipe 2, and a dilution mechanism 6, wherein,

[0023] The air inlet pipe 2 is located on the side wall of the device body 1.

[0024] The dilution mechanism 6 includes multiple mounting columns 62, multiple one-way valves 63, a mounting bracket 64, and a fan 65.

[0025] The outer wall of the intake pipe 2 is provided with multiple mounting holes 61 at equal intervals, multiple mounting posts 62 are installed in the corresponding mounting holes 61, multiple one-way valves 63 are installed in the corresponding mounting posts 62, the mounting bracket 64 is connected to the inner wall of the intake pipe 2, and the fan 65 is installed in the mounting bracket 64.

[0026] Specifically, when the exhaust gas generated by the rotary kiln needs to be treated by the exhaust gas treatment device, the relevant personnel first need to connect the air inlet pipe 2 to the rotary kiln through the connecting pipe, and then turn on the fan 65 with the help of the external control device. At this time, the exhaust gas will enter the air inlet pipe 2 through the connecting pipe, and the fan 65 will deliver air into the interior through the one-way valve 63 to dilute the concentration of the exhaust gas. While diluting, the fan 65 can deliver air into the interior through the gap between the connection points to prevent exhaust gas leakage and achieve the effect of leakage prevention. Then the diluted exhaust gas is delivered to the interior of the device 1 for treatment.

[0027] An exhaust pipe 3 is provided on the side wall opposite to the air inlet pipe 2 on the body 1.

[0028] It is understandable that the treated gas is delivered to other devices or discharged through the gas outlet pipe 3.

[0029] Supporting legs 4 are symmetrically arranged on the bottom wall of the vessel 1.

[0030] Understandably, the support legs 4 prevent the bottom of the device 1 from directly contacting the ground, thus preventing ground moisture from corroding it, causing rust, and shortening its service life.

[0031] A gas monitor 5 is inserted through the outer wall of the vent pipe 3.

[0032] Understandably, the gas monitor 5, which penetrates the outer wall of the outlet pipe 3, can analyze and detect the treated gas in order to observe whether it meets the emission standards and whether the filter inside the device 1 needs to be replaced.

[0033] The inner wall of the air intake pipe 2 is equipped with a dustproof mesh 7.

[0034] It is understandable that the dust filter 7 installed on the inner wall of the air inlet pipe 2 filters out dust particles mixed in the exhaust gas delivered to the air inlet pipe 2, preventing these particles from causing blockage inside the device 1 and thus affecting its normal use.

[0035] In summary, the rotary kiln exhaust gas treatment device of this utility model can introduce air to dilute the high concentration of organic waste gas during the process of treating the exhaust gas generated by the rotary kiln. This helps to avoid the situation where the activated carbon generates a large amount of heat and spontaneously combusts due to a rapid increase in the amount of activated carbon adsorbed in a short period of time.
