Unburned methanol cleaning structure for hearth of methanol hot-blast stove

Abstract

The invention provides an unburned methanol cleaning structure for a hearth of a methanol hot-blast stove. The unburned methanol cleaning structure for the hearth of the methanol hot-blast stove comprises a burner and a fuel cleaning mechanism. A drainage groove is formed in the bottom of the hearth of the burner and is communicated with the outside atmosphere. The fuel cleaning mechanism comprises a water source, a water pump, a water pipe and a spray head. The input end of the water pump is communicated with the water source, the output end of the water pump is communicated with the input end of the water pipe, and the spray head is communicated with the output end of the water pipe. The water pump conveys water in the water source to the spray head through the water pipe. The spray head is contained in the hearth of the burner and arranged at the top of the hearth of the burner. According to the unburned methanol cleaning structure for the hearth of the methanol hot-blast stove, methanol remaining in the hearth of the burner after front scavenging and rear scavenging can be effectively removed, potential safety hazards caused by incomplete cleaning of methanol in the front scavenging and rear scavenging processes are avoided, and the safety performance of a methanol burner is effectively improved.

Description

technical field [0001] The invention relates to the field of burners for methanol hot blast stoves, in particular to a cleaning structure for unburned methanol in the hearth of methanol hot blast stoves. Background technique [0002] The burner of the methanol hot blast stove belongs to the pressure atomization burner. Its working principle is to atomize and spray methanol under the pressure of the fuel pump, and then use the ignition needle to ignite the atomized methanol. The normal operation sequence of the burner should generally meet the following process requirements: fan start → front scavenging → electric spark generated by the electrode → establishment of ignition flame → establishment of main fire flame → normal combustion → main fire flame extinguished → rear scavenging → stop. The pre-scavenging during normal operation refers to the process in which the burner blows the combustible gas with forced air to the furnace before ignition. Post-scavenging refers to the...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to address the technical problems that the traditional methanol hot blast stove burner has a safety hazard that the front and rear sweep air are not cleaned cleanly, and cannot meet the high safety performance requirements of the methanol hot blast stove burner on the market. Provides a structure for cleaning unburned methanol in the hearth of a methanol hot blast stove
