Abstract
The utility model relates to a carbon dioxide recovery system. The carbon dioxide recovery system for a corn fermentation tank solves the problems that existing carbon dioxide recovery is complex in technology, high in cost and lacking in certain pertinence. The carbon dioxide recovery system for the corn fermentation tank comprises the corn fermentation tank and further comprises a carbon dioxide filter device, a compression device, a humidity reducing dust removing device, a cooling device and a storage device which are sequentially communicated and connected. The filter device is a vertical type scrubbing tower and a gas-liquid reverse absorption mode is adopted to process. The compression device is a multistage compressor. The humidity reducing dust removing device is a vertical type absorption tower. A spray nozzle is arranged at the top of the tower. A desiccant and a mesh screen used for filtering small particles are arranged inside the tower. The cooling device is a horizontal type cooler. The storage device is a storage tank of a double-layer container composed of a horizontal type inner and outer container. The carbon dioxide recovery system for the corn fermentation tank achieves recovery of carbon dioxide, guarantees purity of the recovery and is simple in process and low in cost.
Description
Technical field
The utility model relates to a kind of carbon dioxide recovery system, in accordance, relates in particular to a kind of carbon dioxide recovery system, in accordance of corn fermentation tank.
Background technology
The production method of industrial spirit can be divided into fermentation method and two kinds of methods of chemosynthesis, can produce a large amount of carbonic acid gas in the process of the alcohol of fermentative production.Due to Global warming, the discharging of controlling greenhouse gases is a very important strategy, and the recovery of carbon dioxide has very large promotion meaning.Moreover carbonic acid gas has very high using value as the raw materials for production in industry.Have a lot of carbon dioxide recovery technology in prior art, what have reclaims in waste gas, and what have reclaims in air, but their recovery system complexity relatively, and also cost compare is high.The patent No. is the invention of ZL201010130324.9, the patent of invention of " a kind of carbon dioxide recovery system, in accordance " by name is disclosed, relate to the recovery to carbonic acid gas in brewery's fermentation gas, comprise a lot of unit modules in structure, more complicated, and increased gasification unit, so purity requirement is so not high for the carbonic acid gas general applications, this element there is no need, relatively waste.
The utility model content
The purpose of this utility model is: for the deficiencies in the prior art, propose a kind of carbon dioxide recovery system, in accordance of corn fermentation tank, overcome existing carbon dioxide recovery technical sophistication and the higher shortcoming of cost.
The technical solution adopted in the utility model:
a kind of carbon dioxide recovery system, in accordance of corn fermentation tank, comprise the corn fermentation tank, filtration unit, compression set, the wet down cleaning apparatus, refrigerating unit and storing unit, described corn fermentation tank is communicated with the connection filtration unit successively, compression set, the wet down cleaning apparatus, refrigerating unit and storing unit, the carbonic acid gas that the corn fermentation tank produces enters the filtration unit bottom by the corn fermentation tank top, enter compression set by filtration unit top outflow again, enter from wet down cleaning apparatus top, enter refrigerating unit one end by the bottom again, enter storing unit from the other end.
Described filtration unit is vertical washing tower, and inside is provided with from blower fan gas is pressed into, up flow into packing layer and with the reaction of the spray liquid of spray equipment, vertical washing tower is provided with two-stage packing layer and spray equipment.
Described compression set is multi-stage compressor, contains at least a scroll compression body in multi-stage compressor.
Described wet down cleaning apparatus is to be the vertical type absorption tower, and tower top is provided with fog-spray nozzle, and inside comprises siccative and filters the mesh screen of finely ground particles.
Described refrigerating unit is horizontal type cooler, and described storing unit is the hold-up vessel of the double container of horizontal inside and outside container composition.
Described wet down cleaning apparatus is in parallel at least two vertical absorption towers.
Described refrigerating unit is at least two water cooler parallel connections.
Useful positively effect of the present utility model:
The utility model adopts vertical washing tower, is that gas is pressed into or is sucked wind inlet section by centrifugal fan, then travels up to packing layer, with the spray liquid contact reacts, process for gas-liquid conversed absorption pattern, not only can remove gaseous impurities in washings, and can remove solid granule; Stage compression can be compressed into liquid state to carbonic acid gas fully, and some gaseous impuritiess are compressed into liquid state and may need compression not at the same level, has so just again purified carbonic acid gas; The coefficient of heat transfer k value of horizontal type cooler is higher, adopts the hold-up vessel of double container to make storage safer.
