Description

Feed liquid circulation fluidized fermentation device

technical field

The utility model belongs to the field of biogas energy, and in particular relates to a feed liquid circulating fluidized fermentation device.

Background technique

Fermentation biogas production is a practical engineering technology. It uses anaerobic fermentation to treat agricultural and animal husbandry waste, domestic sewage, production wastewater, etc., and at the same time produces high-quality and clean biomass energy—biogas (mainly composed of methane), which is environmentally friendly. , energy, energy saving and emission reduction and many other benefits. However, the traditional biogas project adopts static fermentation process, the fermentation efficiency is low, the gas production rate and pollutant removal rate are not high, which seriously restricts the development of the industry. In recent years, dynamic fermentation technology has been promoted to a certain extent, and has gradually become the mainstream process form of biogas engineering. However, the design of the flow field shape in the existing dynamic fermentation device lacks optimization, and the fermentation feed liquid does not form a complete circulating fluidization path, resulting in low fluidization efficiency of the feed liquid, uneven mixing of materials, and small effective fermentation volume. The unbalanced stirring flow field will easily cause the fermentation raw materials to form bottom accumulation or top crusting, resulting in adverse phenomena such as acidification and low fermentation efficiency. Some poor flow field designs are also likely to cause blockage of materials and damage equipment.

Contents of the invention

The purpose of this utility model is to overcome the lack of optimization in the design of the flow field shape of the existing biogas dynamic fermentation device, and the fermentation raw materials form bottom accumulation or top crusting, resulting in low fermentation efficiency, and provide people with a high fermentation efficiency and low power consumption. Feed-liquid circulating fluidized fermentation device with less and less clogging.

The purpose of this utility model is achieved through the following technical solutions.

The feed-liquid circulating fluidized fermentation device of the present utility model is characterized in that the feed-liquid circulating fluidized fermentation device is composed of a fermentation tank 1 and a water pump 7, the upper part of the fermentation tank 1 is a gas storage room 2, and the bottom of the gas storage room 2 is a fermentation tank. room 3; the top of the fermentation tank 1 is provided with an air duct 11 and a feed inlet 8 with a sealing plug 9; the bottom of the fermentation tank 1 is provided with a water pump outlet 6, the water pump outlet 6 is connected to the water pump 7, and the water inlet of the water pump 7 is connected to the circulation pipe 4 connections; the circulation pipe inlet 5 is arranged around the upper part of the fermentation room 3; the lower side of the fermenter 1 is provided with an inspection port 10.

The utility model arranges circulation pipes around the fermentation tank, and realizes the circulation and fluidization of the feed liquid through the water pump. Its working process is as follows:

The initial fermentation feed liquid enters the fermenter from the top feed inlet, and the feed liquid overflows the height of the circulation pipe, leaving a small space as a gas storage room. Then start the water pump, so that the fermentation feed liquid enters the water pump from the inlet of the circulation pipe along the circulation pipe, and enters the fermentation room from the water outlet of the water pump at a set speed to form a vertical upward water flow. The fermentation feed liquid flows out from the circulation pipe, returns to the inlet of the water pump, and re-enters the fermentation room through the water pump to form a closed circulation system. The circulation system forms fluidization inside, breaks the static fermentation, greatly improves the mixing uniformity of the fermentation feed liquid, greatly improves the gas production rate and avoids problems such as crusting and blockage of the feed liquid.

In summary, the utility model overcomes the lack of optimization in the design of the flow field form of the existing biogas dynamic fermentation device, and the fermentation raw materials form bottom accumulation or top crusting, resulting in low fermentation efficiency. The fermentation efficiency is high, the power consumption is less, and it is not easy to be blocked.
