Problems solved by technology
[0003] The existing gas pulse soot blowing device uses a single pulse of constant pressure. The ash deposits on the furnace wall are divided into shallow and deep layers. Compared with shallow ash deposits, the accumulation time of deep ash deposits is longer , more compact and hard, a single pulse of constant pressure cannot effectively remove deep-seated ash, but continuous superposition of pulse pressure, multiple air blows in a short period of time can effectively remove deep-seated ash, so a pressure Incremental multi-stage pulse soot blowing device is a technical problem to be solved by those skilled in the art

The invention discloses a high-efficiency gas pulse soot blowing device and a control method thereof, and relates to the technical field of boilers. The present invention comprises a boiler wall, an air compressor and a gas cylinder. A soot blowing device is fixedly connected to the side wall of the boiler wall. The soot blowing device includes a first fixing bracket and a second fixing bracket fixed on the side wall of the boiler wall. The wall is fixedly connected with a collar; the inner surface of the collar is fixedly connected with a combustion chamber; The output shaft of a drive motor is fixedly connected with the first pulley. The invention continuously increases the lifting range of the rotary plate through the lateral movement of the conical cam, thereby continuously increasing the opening and closing degree of the throttle valve, and the internal pressure of the combustion chamber is continuously increased, and the pressure is gradually increased. Multiple pulses are more conducive to cleaning deep-seated ash deposits, so that the ash deposits on the inner side of the furnace wall can be completely removed, which is convenient for improving the thermal efficiency of the boiler.
Description
technical field [0001] The invention relates to the technical field of boilers, in particular to a high-efficiency gas pulse soot blowing device and a control method thereof. Background technique [0002] The boiler is an industrial energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. After the boiler is used for a long time, boiler dust will be generated, which will reduce the heat transfer efficiency of the heating surface of the boiler, increase the fuel consumption, and the metal on the heating surface of the boiler is easy to be corroded. The principle of pulse gas sootblowing technology is: ignite the air in the tank and the combustible gas mixer to cause deflagration, and the generated high-temperature and high-pressure gas is ejected from the nozzle of the tank at a very high speed and in t...
