[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1The utility model provides an embodiment: a gas distribution device of a raw coal pyrolysis device, including an air intake pipe 1, an output port of the air intake pipe 1 is fixedly connected to a distribution pipe 2, both left and right ends of the distribution pipe 2 are equipped with connecting components, the other end of the connecting component is fixedly connected to a round pipe 3, the connecting component includes two reducers 9, the two reducers 9 are respectively fixedly connected to the left and right ends of the distribution pipe 2, the other ends of the two reducers 9 are fixedly connected to an elbow 6, and the end of the elbow 6 away from the reducer 9 is connected to the round pipe 3.

[0021] When in use, the gas is input from the air inlet pipe 1 into the distribution pipe 2, and the input gas is divided into two uniform airflows under the action of the distribution pipe 2, so that the two airflows can respectively enter the two reducers 9 and enter the elbow 6 from the reducer 9. At the same time, under the connection of the elbow 6, the two uniform airflows can respectively enter the two circular tubes 3.

[0022] Reference Figure 1 and 2 A plurality of connecting tubes 4 are fixedly connected to the bottom of the circular tube 3, and the plurality of connecting tubes 4 are vertically distributed at the bottom of the circular tube 3. The center distances between two adjacent connecting tubes 4 are equal. An airflow balancing tube 5 is fixedly connected to one end of the plurality of connecting tubes 4 away from the circular tube 3. The plurality of connecting tubes 4 are evenly distributed at the equal dividing point of the airflow balancing tube 5, and a plurality of air outlets 7 are fixedly connected to the outer side of the airflow balancing tube 5.

[0023] When in use, under the action of multiple evenly distributed connecting tubes 4, the gas in the circular tube 3 can be evenly input and flow into the airflow balancing tube 5. At the same time, multiple connecting tubes 4 are evenly distributed at the equal dividing points of the airflow balancing tube 5, so that the gas can evenly enter the airflow balancing tube 5 and fill the airflow balancing tube 5. When the airflow balancing tube 5 is filled with gas, the gas can be output from the air outlet 7 into the burner for use.

[0024] Reference Figure 1-3 The two adjacent air outlets 7 are evenly arranged along the axial direction of the airflow balancing tube 5, and the two air outlets 7 located at the ends of the airflow balancing tube 5 are distributed in a single tube, and explosion-proof plates 8 are fixedly connected to the front and rear ends of the airflow balancing tube 5.

[0025] When in use, due to the action of the evenly distributed air outlets 7, the gas in the airflow balancing tube 5 can flow out evenly. At the same time, the air outlets 7 at both ends of the airflow balancing tube 5 adopt a single-tube distribution, so that the output flow rate of the gas at both ends of the airflow balancing tube 5 is the same as the output flow rate of the gas in the middle, and under the action of the explosion-proof plate 8, the safety of gas transmission in the airflow balancing tube 5 can be improved.

[0026] Working principle: First, the airflow is input from the air inlet pipe 1, and enters the distribution pipe 2 to be evenly distributed into two airflows and enter the circular pipe 3 respectively. After entering the circular pipe 3, the airflow will be evenly distributed to the airflow balance pipe 5 under the connection of multiple connecting pipes 4. When the airflow fills the airflow balance pipe 5, the gas will flow out evenly from the air outlet 7 so that the output flow rates of multiple air outlets 7 are equal, thereby improving the utilization rate of the gas and making the output power of the burner connected to the air outlet 7 more stable.
