Embodiment 1

[0054] When the device is started, the biological filter material with a particle size of 40mm is input into the device through the feed port 2, and reaches the top of the 20mm aperture sieve plate 7 through the circulation channel and the annular deflector 4; The malodorous gas is input into the reactor by the fan 11 with an air volume of 1400 L / min, and is mixed with the water vapor ejected from the humidifier 9 at the same time. The mixed gas enters the reactor through the air inlet 12, and the 20mm aperture sieve plate 7 redistributes the mixed gas. The upward air resistance is given to the biological filter material. At the same time, the gas ejected from the nozzle 3 forms a spin flow in the reactor, and the biological filter material is driven by the gas to form a fluidized state. The first-level reaction chamber 15 reacts, and at this time the malodorous gas can be initially removed; as the reaction progresses, the filter material is gradually consumed, and the particle...

Embodiment 2

[0056] When the device is started, the biological filter material with a particle size of 40mm is input into the device through the feed port 2, and reaches the top of the 20mm aperture sieve plate 7 through the circulation channel and the annular guide plate 4; the air mixed with the ratio of 1:2 and The malodorous gas is input into the reactor by the fan 11 with an air volume of 1400 L / min, and is mixed with the water vapor ejected from the humidifier 9 at the same time. The mixed gas enters the reactor through the air inlet 12, and the 20mm aperture sieve plate 7 redistributes the mixed gas. The upward air resistance is given to the biological filter material.

Abstract

The invention discloses a multistage fluidized bed type biological deodorization device and technique. The multistage fluidized bed type biological deodorization device comprises a bed body, wherein an isolator is arranged in the bed body, wherein a material outlet is formed in the top of the bed body; a gas-solid separation filter net is arranged on the material outlet; an air inlet and a solid residue outlet are formed in the bottom of the bed body; a humidifier and a fan are arranged on the air inlet in sequence; a material inlet is formed in the side wall of the bed body; gas detectors arearranged at the material outlet and the air inlet; multiple sieve plates are arranged in the isolator from bottom to top; sieve meshes of the multiple sieve plates are gradually enlarged from top tobottom; a circulating gap is reserved between the isolator and the side wall of the bed body; a coarse sieve plate is arranged between the position below the isolator and the air inlet; a circulatingchannel is arranged between the isolator and the coarse sieve plate. The deodorization effect is greatly enhanced, and the utilization rate of a filter material is increased; the filter material can be suspended by using redundant energy of the fan, and the utilization rate of the energy is increased; a stable reaction environment can be guaranteed, and the occupied area is smaller; meanwhile, theproblem that a microbial film is blocked by a filler is solved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a multistage fluidized bed biological deodorization device and a process method. Background technique [0002] With the rapid development of China's economy and the rapid improvement of people's living standards, the urbanization process continues to accelerate, and the amount of municipal solid waste treatment has increased sharply. A variety of odorous substances are formed, such as methane, ammonia, mercaptans, hydrogen sulfide, etc. These gases are highly volatile and easily diffuse into the atmosphere, and some gases are toxic and have a strong pungent smell, which seriously affects the lives of residents around the landfill. According to the 2016 case handling statistics of the “12369” environmental reporting hotline of the Ministry of Environmental Protection, in 2016, 35 cases were caused by the stench of landfills, accounting for 2.5% of the total cases handl...
