Description

Technical Field

[0001] The utility model relates to the field of cremation equipment, in particular to a dust treatment device for a cremation furnace. Background Art

[0002] Cremation is a way of disposing corpses, specifically, burning corpses into ashes. The equipment in the crematorium includes a crematorium, a corpse transporter, an ash-collecting vehicle, and subsequent environmental protection treatment equipment. The tail gas generated by cremation contains a large amount of harmful gases, which need to be treated before being discharged. The patent office database search announcement number CN210584137U is a dust treatment device for a crematorium. The dust removal box uses the dust removal frame inside it to absorb heat and intercept dust, and then uses a driven scraper to scrape the dust on the ash-absorbing pad to the discharge chamber. The discharge chamber uses a spiral conveying mechanism to move the fallen ash to the ash storage box for storage and regular cleaning. In this way, the dust particles mixed in the tail gas are quickly removed, and a large amount of dust particles are prevented from entering the purification tank, reducing the amount of purification liquid. However, the dust removal frame absorbs heat and can only intercept part of the dust, and the dust treatment in the flue gas is not ideal. A large amount of dust will still enter the purification tank, causing the purification liquid to be polluted faster, and the purification liquid in the purification tank needs to be replaced frequently;

[0003] Therefore, it is necessary to invent a dust treatment device for a crematorium. Utility Model Content
