Summary of the invention
In order to solve prior art Problems existing, the invention provides a kind of biomass fuel Flash Gas Compression Skid System integrating dedusting, cooling and tar removing function, to replace traditional biomass fuel gas processing system, and reach area occupied little for the purpose of.
In order to realize above object, technical scheme of the present invention is as follows: a kind of biological fuel gas integrated treating device, is made up of the combustion gas dust removal component arranged in a casing and casing, the heat exchange unit cooling combustion gas and filtered tar parts; The gas outlet of described dust removal component is communicated with the fuel gas inlet of heat exchange unit, the gas outlet of described heat exchange unit and filtered tar members.
Further, described combustion gas dust removal component is columnar cavity, and described heat exchange unit comprises vertically arranged set of heat exchange tubes in the water tank of splendid attire water and water tank, and described filtered tar parts are the washing tank of splendid attire water; The gas outlet of described cavity is communicated with the fuel gas inlet of set of heat exchange tubes, and the gas outlet of described set of heat exchange tubes is communicated with washing tank.
Described cavity wall offers the fuel gas inlet of an arranged tangential, and gas outlet is offered on its top, and its bottom is ash output hole.
Described cavity is divided into three sections, and epimere interior diameter is 1.2 ~ 1.5 times of hypomere interior diameter, and stage casing is cone-shaped cavity.
Described set of heat exchange tubes is two groups, is arranged in the outer both sides of cavity respectively; The gas outlet of described cavity is communicated with the fuel gas inlet of one-level set of heat exchange tubes, and the gas outlet of one-level set of heat exchange tubes is all communicated with washing tank with the fuel gas inlet of secondary heat exchange pipe group.
The gas outlet of described one-level set of heat exchange tubes is communicated with collection box, and the fuel gas inlet of secondary heat exchange pipe group is communicated with washing tank, is connected tracheae between collection box with washing tank.
Some nozzles are arranged in described washing tank.
Compared with prior art, the present invention, because setting integrated in casing is except dust parts, the heat exchange unit of cooling down, filtered tar parts, realizes the multi-functional processing power of biological fuel gas, in the reduction biological fuel gas treatment time, improves processing efficiency; Qualified biological fuel gas after process directly supplies gas equipment, need not subsequent disposal link; Whole treatment unit volume is little, saves floor occupying area; Replace tower body spray mode with tank mode of washing, reduce tar water and produce, reduce the expense of water treatment.

Embodiment
Embodiment 1
As shown in Figure 1, biological fuel gas integrated treating device is made up of casing 1, cavity 7, heat exchange box, washing tank 12, blast tube 2 and fuel chamber 5, and casing 1 inside integrally arranges cavity 7, heat exchange box, washing tank 12, blast tube 2 and fuel chamber 5.
Cavity 7 is set in the middle part of casing 1.The syllogic cylinder that cavity 7 is logical in being, epimere interior diameter is 1.3 times of hypomere interior diameter, and stage casing is cone-shaped cavity.Cavity 7 sidewall offers fuel gas inlet 4, and cavity 7 top arranges gas outlet 3.Fuel gas inlet 4 is tangent with sidewall, after combustion gas passes into from fuel gas inlet, and self-forming whirlwind in cavity.
The cabinet space being positioned at cavity 7 periphery is provided as heat exchange box, splendid attire water in heat exchange box, arranges two groups of set of heat exchange tubes in heat exchange box.Heat exchange box is divided into left heat exchange box 14 and right heat exchange box 15.In left heat exchange box 14, one-level set of heat exchange tubes 16 is set, secondary heat exchange pipe group 8 is set in right heat exchange box 15.The top of left heat exchange box 14 sets out the mouth of a river 17, and water-in 13 is offered in bottom, makes water (flow) direction contrary with gas downflow direction.Water-in 6 is offered on the top of right heat exchange box 15, and bottom sets out the mouth of a river 9, makes water (flow) direction contrary with combustion gas up direction.Cavity 7 lower end connects dust collecting box 11.
Casing 1 upper part is separated out blast tube 2 and fuel chamber 5.Blast tube 2 is communicated with gas outlet 3 and one-level set of heat exchange tubes 16 entrance of cavity 7.Fuel chamber 5 and secondary heat exchange pipe group 8 outlet.
Casing 1 bottom arranges washing tank 12, splendid attire water in washing tank 12.One-level set of heat exchange tubes 16 outlet is stretched in water, and secondary heat exchange pipe group 8 entrance and washing tank 12 inner horizontal have clearance space.In order to prevent combustion gas from out carrying a little moisture afterwards from water, secondary heat exchange pipe group 8 ingress arranges water eliminator 10 or scum dredger 10.
