[0002] Water resources are indispensable for the operation of modern society, but the resulting wastewater treatment problem is becoming increasingly severe. With accelerated industrialization and population growth, wastewater composition has become increasingly complex, making traditional treatment methods inadequate. From organic waste and pathogenic microorganisms in domestic sewage to heavy metals, persistent organic pollutants, drug residues, and microplastics in industrial wastewater, wastewater treatment plants are facing unprecedented challenges. Supercritical water oxidation technology can oxidize and decompose organic matter in wastewater, revolutionizing wastewater treatment by achieving zero-pollution discharge, high efficiency, and environmental friendliness, and significantly reducing wastewater treatment costs. The heat treatment component is a crucial technical device for converting ordinary water into supercritical water using supercritical water oxidation technology. Therefore, we propose a combustion component for a supercritical water pulse detonation device. Utility Model Content

[0014] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0015] Combined with appendix Figure 1 and attached Figure 2 As shown, a combustion assembly of a supercritical water pulse detonation device includes a combustion chamber 10, which is provided with a combustion ignition end 11. The combustion ignition end 11 is shaped like a narrowed trumpet and is specifically located at the front end of the combustion chamber 10. The rear end of the combustion chamber 10 is shown in the attached figure. Figure 3 As shown, it is connected to the pulse detonation chamber of the supercritical water pulse detonation device. An igniter 20 is installed at the combustion ignition end 11, and an internal pressure controller 30 for controlling the internal pressure of the combustion chamber 10 is provided at the port of the combustion ignition end 11. The internal pressure controller 30 is specifically installed on the lower side of the combustion ignition end 11.
[0016] Since the wastewater may contain nitro compounds (such as TNT) or nitrogen-rich organic matter, it will release some N2H4 or NH3 in the early stage of the oxidation reaction. The internal pressure controller 30 can control the internal pressure of the combustion chamber 10 to ensure that the combustion chamber 10 will not burst due to excessive internal pressure when burning N2H4 or NH3.
[0017] Combined with appendix Figure 1As shown, two igniters 20 are symmetrically arranged on the upper and lower sides of the combustion ignition end 11. Each igniter 20 has an arc-shaped mounting base 21 on the conical surface of the combustion ignition end 11. The igniter 20 can ignite N2H4 or NH3 within the combustion chamber 10. The heat energy generated by the ignition of N2H4 or NH3 can be output to the outside through a heat transfer pipe to supply heat energy to the heating chamber of the supercritical water pulse detonation device.
[0018] Combined with appendix Figure 2 As shown, the combustion chamber 10 has an annular mounting base 31 at the combustion ignition end 11 for installing the internal pressure controller 30. The annular mounting base 31 has a connecting adjustment column, and the internal pressure controller 30 is installed on the connecting adjustment column 32. The installation height of the internal pressure controller 30 can be adjusted at the connecting adjustment column 32.
[0019] This invention enables the combustion of some N2H4 or NH3 released from wastewater during the initial oxidation reaction. The heat generated by the combustion can be output to the outside through a heat transfer pipeline to supply heat energy to the heating chamber of the supercritical water pulse detonation device.
