Description

Technical Field

[0003] At present, catalytic combustion is generally carried out through the combustion of gas, and the combustion efficiency of the gas determines the efficiency of the catalytic combustion; however, the combustion efficiency of general catalytic combustion is not high, so the combustion efficiency of the gas needs to be improved. This application document is a structural improvement made to improve the combustion efficiency of the gas. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency fully automatic catalytic combustion device, which can effectively solve the above-mentioned problems.

[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0022] See also Figure 1-3 This is an embodiment of a high-efficiency fully automatic catalytic combustion device of the utility model.

[0023] It includes a combustion box 1 with a gas and air mixing inlet and an exhaust port 7; a gas mixing section 2 connected to the gas and air mixing inlet is arranged in the combustion box 1; an ignition section 13 is also arranged in the combustion box 1, the ignition section 13 is arranged on one side of the gas mixing section 2, and a spark plug 11 is arranged on the top of the ignition section 13; a combustion chamber is also arranged in the combustion box 1, and a catalyst 12 is installed in the combustion chamber.

[0024] When the combustion box 1 of the present device is performing catalytic combustion, it is necessary to introduce fuel gas and oxygen for fuel gas combustion into the combustion box 1, and then utilize the spark plug 11 to ignite the fuel gas to make it burn. Then the burning fuel gas approaches the catalyst 12 located in the combustion chamber, and the catalytic combustion speed of the catalyst 12 reaches a predetermined value.

[0025] The efficiency of catalytic combustion is affected by the combustion efficiency of the gas provided, and the combustion efficiency of the gas is affected by the ratio and mixing efficiency of the gas and oxygen; so if you want to improve the efficiency of catalytic combustion, you need to improve the combustion efficiency of the gas, that is, the mixing efficiency of the gas and oxygen.

[0026] The present application document improves the mixing structure of gas and air - the gas mixing part 2; the gas mixing part 2 includes a mixing cylinder 3, the cylinder wall of the mixing cylinder 3 is uniformly arrayed with air holes 4, and the inner wall of the mixing cylinder 3 is provided with spiral blades 5;

[0027] Usually, gas and air are added into the mixing cylinder 3 together and then mixed evenly. During the mixing, the high-pressure airflow carries the gas into the mixing cylinder 3. The travel of the airflow and gas can be increased along the guidance of the spiral blades 5. Compared with directly filling into the vertical mixing cylinder 3, the airflow travels in a curve and the travel is longer. At the same time, the spiral blades 5 will also interfere with the flow direction of the airflow to allow the gas and air to be fully mixed. This can improve the mixing efficiency of the gas and air, thereby achieving the purpose of improving the catalytic combustion efficiency.

[0028] The ignition part 13 of the device is a space, and the gas and air will enter the space from the air hole 4 after mixing, and then the spark plug 11 can ignite.

[0029] In this device, the gas and air need strong pressure to enter the mixing cylinder 3, so this application document is provided with a three-way pipe 8, a fuel injector 9 is provided in the main pipeline of the three-way pipe 8, a gas injector 10 is provided in the secondary pipeline of the three-way pipe 8, and the main pipeline of the three-way pipe 8 is connected with the gas mixing part 2. The injector of this application document can be a nozzle.

[0030] Air can be introduced into the three-way pipe 8 through the gas injector 10, and fuel gas can be introduced into the three-way pipe 8 through the fuel injector 9. Such an arrangement can provide strong pressure for air and gas, improve the speed of air and gas entry and the mixing efficiency.

[0031] The blade width of the spiral blade 5 is equal to one third of the diameter of the mixing cylinder 3 .

[0032] With such arrangement, the spiral blade 5 does not completely block the passage inside the mixing cylinder 3, but reserves an intermediate vertical channel. The purpose of leaving the vertical channel is to prevent the efficiency of the gas introduced per unit time from being reduced due to the elongation of the airflow path.

[0033] A heat exchanger 6 is also provided at the exhaust port 7 of the combustion box 1 .

[0034] The device is provided with a heat exchanger 6 at the exhaust port 7 of the combustion box 1 because the heat energy generated by the catalytic combustion can be absorbed by the heat exchanger 6 and reused, thus achieving an energy-saving effect.

[0035] The exhaust port 7 is arranged at one side of the combustion box 1 , the heat exchanger 6 is installed in the middle of the exhaust port 7 , and the area of ​​the exhaust port 7 is larger than the area of ​​the heat exchanger 6 .

[0036] Since the installation of the heat exchanger 6 will affect the exhaust, the size of the exhaust port 7 is designed to be larger than the area of ​​the heat exchanger 6, and the excess gas can be discharged through the part other than the heat exchanger 6.

[0037] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
