Abstract

The invention relates to an original-state sludge storing, unloading and deodorizing device and method. The original-state sludge storing, unloading and deodorizing device comprises a sludge groove, a flat helix, a stirring helix, a discharging helix and a deodorizing fan. An electric door is arranged on the loading side of the top of the sludge groove. A top cover is arranged on the top of the sludge groove. An exhausting pipe is arranged in the middle of the top cover and connected with a combustion air inlet pipeline of a combustion furnace through the deodorizing fan. The flat helix is arranged on the upper portion of the sludge groove, and the discharging helix is arranged on the bottom of the sludge groove. A sludge discharging opening is formed in the bottom of the discharging helix. The stirring helix is arranged above the discharging helix. The device can meet the requirements for storing original-state sludge conveniently, achieving smooth unloading and preventing the situation that odor escapes and pollutes atmosphere. Moreover, the internal capacity of the sludge groove can be utilized fully, gas in the sludge groove can serve as combustion air of the combustion furnace to participate in combustion, good economical and social benefits are achieved, and the market prospect is considerable.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to an original sludge storage, unloading and deodorization device and method. Background technique [0002] Since the beginning of the 21st century, with the rapid development of my country's industry, the increasing trend of the amount of sludge produced by sewage treatment plants is also very obvious. The composition of sludge is relatively complex, especially the original sludge produced by sewage treatment plants, which has relatively stable solid matter, of which the proportion of organic biomass in the solid matter accounts for about 60%, which has a certain calorific value, and the composition of inorganic matter is about Accounted for 40%, moisture content accounted for more than 80%. The dehydration of raw sludge generally needs to be dehydrated by drying equipment, and then supplied to the combustion furnace as fuel. Before the original sludge is dried and dehyd...
