Embodiment 1

[0020] As shown in Figure 1, the thermal explosion pulse sootblower of this embodiment mainly includes a pulse generator 1, a mixed gas pipeline 2, an electrolyzed water-oxygen generator 3; the outlet of the electrolyzed water-hydrogen generator 3 and the pulse generator The inlets of 1 are connected through the mixed gas pipeline 2; the output of the electrolyzed water hydrogen-oxygen generator 3 is hydrogen-oxygen mixed gas.

[0021] When carrying out soot blowing operation, first energize the electrolytic water hydrogen-oxygen generator 3 to generate hydrogen-oxygen mixed gas, which is sent to the pulse generator 1 through the mixed gas pipe 2, and the hydrogen-oxygen mixed gas filled in the pulse generator 1 meets the requirements , the hydrogen-oxygen mixture in the pulse generator 1 can be detonated.

Embodiment 2

[0023] As shown in accompanying drawing 2, the thermal explosion pulse soot blower of the present embodiment mainly includes a pulse generator 1, a mixed gas pipeline 2, an oxygen pipeline 10, a hydrogen pipeline 11, and an electrolyzed water hydrogen-oxygen generator 3; The oxygen generator 3 is connected with the pulse generator 1 through the oxygen pipeline 10, the hydrogen pipeline 11 and the mixed gas pipeline 2. A replenishment valve 13 is connected in series; an oxygen switch valve 8 and a check valve 6 are connected in series on the oxygen pipeline 10 along the gas flow direction, and a hydrogen switch valve 9 and a check valve are connected in series on the hydrogen pipeline 11 along the gas flow direction. Valve 7; a mixer 5 is connected in series on the hydrogen-oxygen mixture pipeline 2, and another purge gas pipeline 14 is connected to the hydrogen-oxygen mixture pipeline, and the ignition head 4 is installed on the mixer 5.

Abstract

The invention belongs to the thermal explosion pulse soot blowing technical field, in particular relating to an oxyhydrogen thermal explosion pulse soot blower, which mainly comprises a pulse generator and a water electrolysis oxyhydrogen generator. An air outlet of the water electrolysis oxyhydrogen generator is connected with an inlet of the pulse generator. The pulse soot blower has the main advantages of only water and electric energy consumption, safety and reliability, and good soot blowing effect.

Description

technical field [0001] The invention belongs to the technical field of thermal explosion pulse soot blowing, in particular to a hydrogen-oxygen thermal explosion pulse soot blower, in particular to a thermal explosion pulse soot blower with hydrogen as fuel and oxygen as oxidant. Background technique [0002] Thermal explosion pulse sootblower is referred to as pulse sootblower, also known as shock wave sootblower, shock wave sootblower, weak explosion sootblower, detonation wave sootblower, detonation wave sootblower, detonation pulse sootblower, etc. , was first invented by the former Soviet Union and introduced to my country in 1988. It evolved from the "gas cannon". Internal ignition explosion, using the "alternating stamping and suction effect" of the compression shock wave generated by the explosion, the "physical micro-explosion effect" and the "purge effect" of the high-speed pulse jet to blow off various accumulations on the heating surface of the boiler and the wall ...
