Abstract
Description
Technical Field
[0001] This utility model relates to the field of organic waste gas treatment, and in particular to a mixing chamber for organic waste gas treatment. Background Technology
[0002] Organic waste gas treatment includes collection, pretreatment, treatment (such as combustion, adsorption, biological treatment, etc.), and then discharge. The mixing chamber is part of the pretreatment and is used to mix waste gases of different concentrations or temperatures to make them uniform and facilitate subsequent treatment. Since the concentration of waste gas generated by the process may fluctuate greatly, directly entering catalytic combustion or RTO may affect efficiency or even pose safety hazards. At this time, the mixing chamber is needed to homogenize the concentration and temperature.
[0003] In existing mixing chambers, multiple streams of waste gas are typically introduced into the mixing chamber through the air inlet, and then the airflow is forced to be disturbed by the agitator to achieve homogenization of concentration and temperature. However, because the organic waste gas contains corrosive gases (such as sulfur dioxide), it can corrode the blades and other structures of the agitator, making the agitator prone to damage and resulting in significant maintenance costs. Utility Model Content
[0004] In view of this, the present invention provides a mixing chamber for treating organic waste gas. The main technical problem to be solved is to optimize the mixing device of the mixing chamber to avoid corrosive gases from corroding the blades and other structures of the mixing device, thus avoiding large maintenance costs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mixing chamber for treating organic waste gas, comprising a main body, a mixing mechanism installed inside the main body, an air intake mechanism installed inside the mixing mechanism, and multiple air intake mechanisms; the main body includes a shell, the mixing mechanism includes a mixing cylinder, the mixing cylinder is fixedly installed inside the shell, a connection port is opened on the outer surface of the mixing cylinder, the air intake mechanism includes an outer pipe, the outer pipe is fixedly installed inside the mixing cylinder, a first outlet is opened on the outer surface of the outer pipe, an inner pipe is movably connected inside the outer pipe, and a second outlet is opened on the outer surface of the inner pipe.
[0006] By adopting the above technical solution, multiple streams of organic waste gas are introduced into different inner pipes during use. The organic waste gas passes through the second outlet on the inner pipe and the first outlet on the outer pipe and enters the mixing cylinder. The multiple streams of organic waste gas entering the mixing cylinder will generate airflows in different directions, allowing the multiple streams of organic waste gas to interfere with each other and mix in the mixing cylinder. The mixed organic waste gas will move to the connection port on the left side of the mixing cylinder and be discharged into the outer shell. Finally, it will move to the discharge pipe on the right side of the outer shell and be discharged. By rotating the inner pipe to adjust the position of the second outlet, the size of the common gap between the first and second outlets can be changed, thereby changing the discharge flow rate of the organic waste gas, which facilitates the uniform mixing of waste gas from different sources and with different concentrations.
[0007] As a further description of the above technical solution:
[0008] The connection port is located on the left side of the outer surface of the mixing cylinder, the first outlet is located on the right side of the outer surface of the outer tube, the second outlet is located on the right side of the outer surface of the inner tube, and the position of the second outlet corresponds to the position of the first outlet.
[0009] By adopting the above technical solution, the travel distance of organic waste gas can be increased, the residence time of organic waste gas inside the shell can be increased, and the organic waste gas can be better mixed.
[0010] As a further description of the above technical solution:
[0011] The left side wall of the outer casing has a mounting hole, and the left side wall of the mixing cylinder has a through hole. The position of the mounting hole corresponds to the position of the through hole.
[0012] By adopting the above technical solution, it is easy to install the inner pipe, so that the organic waste gas can enter the mixing drum through the inner pipe for mixing.
[0013] As a further description of the above technical solution:
[0014] The left end of the inner tube extends through the through hole and the mounting hole to the outside of the outer shell.
[0015] By adopting the above technical solution, it is easier for organic waste gas to enter the inner pipe.
[0016] As a further description of the above technical solution:
[0017] A sealing ring is installed inside the mounting hole, and the sealing ring is movably connected to the outer surface of the inner tube.
[0018] By adopting the above technical solution, the sealing performance between the outer shell and the inner tube is increased. The sealing ring is a dynamic seal, and the inner tube can be rotated, which facilitates the adjustment of the common gap size between the first outlet and the second outlet.
[0019] As a further description of the above technical solution:
[0020] A discharge pipe is fixedly connected to the top of the outer shell. The discharge pipe is connected to the interior of the outer shell and is located on the right side of the outer shell.
[0021] By adopting the above technical solution, the mixed organic waste gas inside the shell can be discharged.
[0022] By employing the above technical solution, the mixing chamber for treating organic waste gas of this utility model has at least the following beneficial effects:
[0023] 1. Compared with existing technologies, this mixing chamber for treating organic waste gas introduces multiple streams of organic waste gas into different inner pipes. The organic waste gas passes through the second outlet on the inner pipe and the first outlet on the outer pipe into the mixing cylinder. The multiple streams of organic waste gas entering the mixing cylinder generate airflows in different directions, allowing them to interfere with each other and mix. The mixed organic waste gas then moves to the connection port on the left side of the mixing cylinder and exits into the outer shell, finally moving to the discharge pipe on the right side of the outer shell for discharge. Compared with existing mixing chambers that use a stirring device to force airflow disturbance, which increases the maintenance cost of the mixing chamber, this mixing chamber for treating organic waste gas has a simple structure, can fully mix multiple streams of organic waste gas, and is easy to maintain.
[0024] 2. Compared with the existing technology, the mixing chamber for treating organic waste gas can change the size of the common gap between the first and second outlets by rotating the inner tube to adjust the position of the second outlet, thereby changing the discharge flow rate of organic waste gas and making it easier to mix waste gas from different sources and with different concentrations evenly.

[0031] Reference Figure 1-4 This utility model provides a mixing chamber for treating organic waste gas: it includes a main body 1, a mixing mechanism 2 installed inside the main body 1, and multiple air inlet mechanisms 3 installed inside the mixing mechanism 2 to facilitate the addition of multiple streams of organic waste gas into the mixing mechanism 2 for mixing. The main body 1 includes a shell 101, the mixing mechanism 2 includes a mixing cylinder 201, which is fixedly installed inside the shell 101, and the outer surface of the mixing cylinder 201 has a connection port 202. The air inlet mechanism 3 includes an outer pipe 301, which is fixedly installed inside the mixing cylinder 201, and the outer surface of the outer pipe 301 has a first outlet 302. An inner pipe 303 is movably connected inside the outer pipe 301, and the outer surface of the inner pipe 303 has a second outlet 304. In use, multiple streams of organic waste gas are introduced into different inner pipes 303 respectively, and the organic waste gas will pass through the second outlet 304 on the inner pipe 303 and the first outlet 304 on the outer pipe 301. The gas enters the mixing cylinder 201 through outlet 302. Multiple streams of organic waste gas entering the mixing cylinder 201 will generate airflows in different directions, allowing the multiple streams of organic waste gas to interfere with each other and mix within the mixing cylinder 201. The mixed organic waste gas will move to the connection port 202 on the left side of the mixing cylinder 201 and be discharged, entering the interior of the outer shell 101. Finally, it will move to the discharge pipe 104 on the right side of the outer shell 101 and be discharged. By rotating the inner tube 303 to adjust the position of the second discharge outlet 304, the size of the common gap between the first discharge outlet 302 and the second discharge outlet 304 can be changed, thereby changing the discharge flow rate of the organic waste gas. This facilitates the uniform mixing of waste gas from different sources and with different concentrations. The discharge pipe 104 is fixedly connected to the top of the outer shell 101 and is connected to the interior of the outer shell 101. The discharge pipe 104 is located on the right side of the outer shell 101, allowing the mixed organic waste gas inside the outer shell 101 to be discharged.
[0032] The connection port 202 is located on the left side of the outer surface of the mixing cylinder 201, the first outlet 302 is located on the right side of the outer surface of the outer tube 301, and the second outlet 304 is located on the right side of the outer surface of the inner tube 303. The position of the second outlet 304 corresponds to the position of the first outlet 302, which can increase the travel distance of the organic waste gas and increase the residence time of the organic waste gas inside the outer shell 101, so as to facilitate better mixing of the organic waste gas.
[0033] The left side wall of the outer shell 101 is provided with a mounting hole 102, and the left side wall of the mixing cylinder 201 is provided with a through hole 203. The position of the mounting hole 102 corresponds to the position of the through hole 203. The left end of the inner tube 303 passes through the through hole 203 and the mounting hole 102 in sequence and extends to the outside of the outer shell 101, so as to facilitate the installation of the inner tube 303 and allow the organic waste gas to enter the mixing cylinder 201 through the inner tube 303 for mixing.
[0034] A sealing ring 103 is installed inside the mounting hole 102. The sealing ring 103 is movably connected to the outer surface of the inner tube 303, which increases the sealing between the outer shell 101 and the inner tube 303. The sealing ring 103 is a dynamic seal, and the inner tube 303 can be rotated to facilitate adjustment of the common gap size between the first outlet 302 and the second outlet 304.
[0035] Working principle: During use, multiple streams of organic waste gas are introduced into different inner pipes 303. The organic waste gas will pass through the second outlet 304 on the inner pipe 303 and the first outlet 302 on the outer pipe 301 and enter the mixing cylinder 201. The multiple streams of organic waste gas entering the mixing cylinder 201 will generate airflow in different directions, which will allow the multiple streams of organic waste gas to interfere with each other and mix in the mixing cylinder 201. The mixed organic waste gas will move to the connection port 202 on the left side of the mixing cylinder 201 and be discharged, entering the interior of the outer shell 101, and finally moving to the discharge pipe 104 on the right side of the outer shell 101 and being discharged.
