Device for treating cremation waste gas of cremation furnace

Abstract

The invention relates to the technical field of waste gas treatment, and discloses a device for treating cremation waste gas of a cremation furnace. The device comprises a cylinder body, wherein an opening is formed in the upper side of the cylinder body; a filter screen is arranged in the opening; the edge of the filter screen is fixedly connected to the cylinder body; and a dust removal mechanism is arranged inside the cylinder body. During use, the lower end of the cylinder body is connected to a gas outlet of the cremation furnace in a sleeving manner, and gas flow is filtered and discharged from the filter screen. Gas bags expand to slowly lift a stabilizing ring due to the fact that the temperature of the cremation waste gas is extremely high. A sliding mechanism can adapt to rotation and twisting at various angles due to the fact that a spiral rod is spiral. A second elastic hook and a first elastic hook are in deformable connection with an elastic sheet. Therefore, the sliding mechanism has the effect of enabling a fixing ring to rotate gently when the spiral rod moves upwards so as to enable a brush to brush and loosen dust on the filter screen and enable a dust scraping mechanism to scrape off the dust, so that a self-cleaning effect is achieved. The dust can be better scraped off through the dual function of a first scraping blade and a second scraping blade.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a cremation furnace waste gas treatment device. Background technique [0002] Influenced by the traditional funeral rites of the Chinese nation, some other items need to be burned when the remains are cremated, and some air pollutants will also be produced when the remains are burned. These substances are basically particulate matter, sulfur dioxide, carbon monoxide, hydrogen chloride, nitrogen oxides, dioxins, etc. Like the cremated remains, it is also discharged through the exhaust pipe, and the direct discharge of harmful substances into the atmosphere will pollute the atmospheric environment. However, under the existing environment, ordinary small crematoria cannot purchase large-scale waste gas due to their scale and financial reasons. Purification equipment, so the exhaust gas is generally filtered. Due to the particularity of cremation exhaust gas, the filter ...

Problems solved by technology

Like the cremated remains, it is also discharged through the exhaust pipe, and the direct discharge of harmful substances into the atmosphere will pollute the atmospheric environment. However, under the existing environment, ordinary small crematoria cannot purchase large-scale waste gas due to their scale and financial reasons. Purification equipment, so the exhaust gas is generally filtered. Due to the particularity of cremation exhaust gas, the filter screen will be blocked after a long time. Therefore, an exhaust gas filter device that can self-clean the filter screen is needed.
