Abstract
The purifying agent for treating stalk gas consists of calcium hydroxide 3-4 weigh portions, sodium bicarbonate 1-1.5 weigh portions, potassium carbonate 1.5-2 weigh portions, borax 0.5-1 weigh portions, magnesium chloride 0.5-1.5 weigh portion, sodium dodecyl sulfonate 1.5-2.5 weigh portions, sodium sulfate 0.1-0.2 weigh portion, and active carbon 0.1-0.5 weigh portion. The purifying agent containing metal salts is dissolved in water to form solution for replacing, neutralizing, adsorbing, cracking, dissolving and washing tar, impurity gas and corrosive gas. It is reuseable, and has obvious effect of eliminating tar and other impurities and no environmental pollution.
Description
Technical field
The present invention relates generally to a kind of scavenging agent, relates in particular to a kind of scavenging agent that is used for handling carbonic acid gas, sulfurous gas, wood tar oil, wood vinegar and other impurity component that the Straw Gas generative process produced.
Background technology
Straw Gas is that biomass materials such as agricultural crop straw are pulverized, burn incompletely under anoxic condition, thereby a large amount of combustible gases based on carbon monoxide that produce.In the generative process of Straw Gas usually with the generation of carbonic acid gas, sulfurous gas, wood tar oil, wood vinegar and other impurity component.The quality of the coal-tar middle oil processing of Straw Gas is the key that advances rural area fuel revolution.Find that in the use of Straw Gas the tar that is mingled with in the Straw Gas can cause problems such as gas meter stops up, pipeline is not smooth, valve is killed.Impurity such as corrosive gases such as carbonic acid gas wherein, sulfurous gas and wood vinegar thereof can make metal products corrosion in various degree occur, and damage in various degree appears in the production unit that is made of metal, and other impurity also will influence the use of Straw Gas.Impurity component in the Straw Gas makes the calorific value of this Straw Gas descend, and has a strong impact on its service efficiency.
Summary of the invention
The object of the invention provides a kind of scavenging agent that is used to handle Straw Gas, and it can effectively remove tar, corrosive gases and other impurity that is mingled with in the Straw Gas.
The present invention can be implemented by the following technical programs:
A kind of scavenging agent that is used to handle Straw Gas, described scavenging agent is mainly mixed by the raw material of following weight part:
3～4 parts calcium hydroxide;
1～1.5 part sodium bicarbonate;
1.5～2 parts salt of wormwood;
0.5～1 part borax;
0.5～1.5 parts magnesium chloride;
1.5～2.5 parts sodium laurylsulfonate.
Described scavenging agent also comprises the raw material of following weight part: 0.1～0.2 part sodium sulfate, 0.1～0.5 part gac.
The weight part consumption of each raw material in the described scavenging agent is: 3 parts calcium hydroxide, 1 part sodium bicarbonate, 1.5 parts salt of wormwood, 0.5 part borax, 0.5 part magnesium chloride, 2 parts sodium laurylsulfonate, 0.1 part sodium sulfate, 0.1 part gac.
Compared with the prior art the present invention has following advantage: described scavenging agent contains metal-salt, in use wants water-soluble formation solution, is used for displacement, neutralization, absorption, cracking, dissolving, washing tar and foreign gas, etchant gas; Described scavenging agent all recycles, non-environmental-pollution in use, and it is obvious to remove impurity effect such as tar, and after tested, the accessible index of Straw Gas is after purifying: the content of tar is less than 2mg/m
3, the burning of gas temperature can reach 640 degrees centigrade, and the content of etchant gas (in sulfate radical) is less than 0.01mg/m

Embodiment
The configuration scavenging agent: the weight part consumption of each raw material in the wherein said scavenging agent is: 3 parts calcium hydroxide, 1 part sodium bicarbonate, 1.5 parts salt of wormwood, 0.5 the borax of part, 0.5 part magnesium chloride, 2 parts sodium laurylsulfonate, 0.1 the sodium sulfate of part, 0.1 part gac.
To drop in the circulatory pool for 1000 kilograms according to the scavenging agent of mentioned component configuration, constantly wash, described scavenging agent is dissolved in fully form the scavenging agent aqueous solution in the pond stand-by with submersible pump.
At first Straw Gas is sprayed with the prepared scavenging agent aqueous solution, then adopt circulating water filtration again, and then adopt the state type water filtration again, filter by the two-stage wood chip again, at last again by a water filtration, make that the compositions such as tar of Straw Gas are purified completely, finally enter gas-holder, supply with the user and use.
In said process, the employed water of water filtration all is the scavenging agent aqueous solution that makes in circulatory pool; In the wherein last water filtration, in the filtration chamber, add some scavenging agents, but the concentration of the scavenging agent aqueous solution must not surpass 20 degree Beaume; Should keep the liquid level in the filtration chamber in state type water filtration process is 30 cm heights; When the pH value of the scavenging agent aqueous solution in the circulatory pool less than 7 the time, should reconfigure.
