[0003] However, in the current prior art, at the position where the waste gas pipeline of the preheater is connected to the C1 cyclone, due to the direction of the wind and the problem of not being able to accumulate materials, the top of the waste gas pipeline is relatively high and occupies a large space, increasing the weight of the equipment and reducing the earthquake resistance and the ability to resist strong winds. Content of the Utility Model
[0004] The purpose of the utility model is to provide a gas-solid separation structure for the waste gas pipeline at the outlet of a preheater to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:

A processing component for gas-solid separation of the waste gas in the preheater is arranged inside the housing. The processing component includes two cyclones arranged at the top of the housing. Two guiding pipes are arranged at the top of each of the two cyclones. The other ends of the two guiding pipes are both provided with air pipes. One end of the air pipe is provided with a separation chamber, and the other end is provided with a waste gas pipeline. A fan is arranged outside the waste gas pipeline.

[0011] As a preferred embodiment of the present utility model, a separation filter screen is installed inside the separation chamber, which is used to isolate the raw materials in the waste gas and make the raw materials adhere.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: In response to the problems raised in the background art, this application adopts a processing component. By adding a gas-solid separation chamber between the C1 cyclone and the waste gas pipeline, while changing the direction of the air, the raw materials in the waste gas are isolated by the separation filter screen, and the raw materials are adsorbed for gas-solid separation; the structure of the separation chamber is simple and convenient to manufacture and install, and changing the direction of the air reduces the height of the waste gas pipeline, making the system structure more reasonable and safe; increasing gas-solid separation reduces the wear of the 506 fan by particles, indirectly reducing the operating cost, and increasing the gas-solid separation effect, reducing the ineffective cycle, and achieving the purpose of energy conservation and emission reduction.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model.
[0018] Embodiment
[0019] Please refer to Figure 1-2, the present utility model provides a technical solution: a gas-solid separation structure for the waste gas pipeline at the outlet of the preheater, including a housing 1. Inside the housing 1, a processing component is provided for gas-solid separation of the waste gas in the preheater. The processing component includes two cyclones 2 arranged at the top of the housing 1 for spirally conveying the waste gas. At the top of each of the two cyclones 2, two guiding pipes 201 are provided for guiding the angle of the waste gas when it is output from the preheater. The other ends of the two guiding pipes 201 are each provided with a gas pipe 3 for guiding and conveying the waste gas after gas-solid separation. One end of the gas pipe 3 is provided with a separation chamber 301, which has an annular structure inside, for changing the conveying direction of the waste gas to reduce the height of the waste gas pipeline and make the system structure more reasonable and safe. And a separation filter is installed inside to isolate the raw material in the waste gas and adsorb the raw material to separate the raw material from the waste gas. The other end is provided with a waste gas pipeline 4, and a fan 5 is arranged outside the waste gas pipeline 4.
[0020] In the old preheater, the waste gas pipeline is connected to the position of the C1 cyclone. Due to the direction of the wind and the problem of not being able to accumulate materials, the top of the waste gas pipeline is relatively high and occupies a large space, increasing the weight of the equipment and reducing the anti-seismic and anti-strong wind capabilities. The current structure does not have a gas-solid separation device, and there is a lot of high-temperature raw material in the waste gas. The raw material will carry away heat and be separated from the gas by the dust collector and recycled back into the preheater system, which causes waste of heat. Moreover, the high-temperature raw material will extremely quickly wear the blades of the 506 fan, increasing the operating cost.
[0021] In this embodiment, all electrical components are controlled by a conventional controller.
[0022] For the embodiment, please refer to Figure 1-2 , the two cyclones 2 are each inlaid and connected to the top of the housing 1. One end of each of the two guiding pipes 201 extends into the cyclone 2, and the other end is connected to one end of the gas pipe 3 through a sleeve. The separation chamber 301 is located at one end of the gas pipe 3 close to the guiding pipe 201 and is externally connected to the gas pipe 3 through a sleeve. The inside of the separation chamber 301 is a spiral structure and is communicated with the inside of the gas pipe 3 and the guiding pipe 201. The spiral structure changes the air flow direction when the waste gas passes through. The other end of the gas pipe 3 extends into the waste gas pipeline 4, and the waste gas pipeline 4 is connected to the air inlet of the fan 5. A separation filter is installed inside the separation chamber 301 for isolating the raw material in the waste gas and making the raw material adhere. When in use, first, a signal is sent from the control center to the PLC controller. The PLC controller controls the cyclone 2 to cooperate with the fan 5 to convey the waste gas in the preheater, and it is conveyed through the guiding pipe 201 and extends into the waste gas pipeline 4 through the gas pipe 3. After entering the gas pipe 3, it will pass through the separation chamber 301. The separation chamber 301 changes the conveying direction of the waste gas and isolates the raw material in the waste gas through the internal separation filter and adsorbs the raw material to separate the raw material from the waste gas.
[0023] Working process of the utility model: When in use, the control center first sends a signal to the PLC controller. The PLC controller controls the cyclone 2 to cooperate with the fan 5 to convey the waste gas in the preheater, and through the guiding pipeline 201, it extends into the waste gas pipeline 4 for conveying through the air pipe 3. After entering the air pipe 3, it will pass through the separation chamber 301, change the direction of the waste gas conveyance through the separation chamber 301, and isolate the raw meal in the waste gas through the internal separation filter screen, and adsorb the raw meal to separate the raw meal from the waste gas. The utility model realizes the gas-solid separation of the waste gas in the preheater, reduces the wear of the equipment, and increases the energy conservation and emission reduction effect.
[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
