The modified device can be made to be in skid-mounted moving type, and can be used for treating the straw gas in scattered straw gas holder stations. The energy efficiency is high, and the calorific value of the straw gas can be increased from about 2000Kcl /Nm3 to 5000-8500Kcl/Nm3 in short time.
Description
Technical field
The utility model belongs to the biomass applied technical field, particularly a kind of Straw Gas later use technical field.
Background technology
Straw Gas is a kind of mixed gas that mainly contains components such as carbon monoxide, carbonic acid gas, hydrogen, methane, and its methane content is no more than 20% usually, and calorific value is only at 1000～2000Kcal/Nm
3Between.This Straw Gas is mainly used at present and supplies with common people's cooking and adopt dim because calorific value is lower.The use report that replaces coal to generate electricity with Straw Gas is also arranged, but, certain limitation is arranged because calorific value is lower.The low scope of utilizing that has seriously restricted Straw Gas of methane content in the Straw Gas makes huge stalk resource be difficult to make full use of.
The utility model content
The purpose of this utility model provides a kind of reforming apparatus that improves the Straw Gas calorific value.
The reforming apparatus of this raising Straw Gas calorific value is made of convertor, condenser, gas-liquid separator, adsorption cleaning device and Straw Gas gas path pipe, the conversion gas gas path pipe of compressor, preheater, synthetic carbon monoxide and hydrogen, wherein, the Straw Gas gas path pipe passes preheater and is connected between compressor outlet and the convertor inlet, and conversion gas gas path pipe passes condenser and is connected between convertor outlet and the gas-liquid separator inlet and is connected the gas-liquid separator outlet and between the adsorption cleaning device enters the mouth.
During work common Straw Gas is inserted the suction port of compressor, after being heated to temperature of reaction, preheater is input in the convertor of synthetic carbon monoxide and hydrogen, make that more low-calorie carbon monoxide and hydrogen generation catalyzed reaction are converted into the high heating value methane gas in the Straw Gas, promptly improve the content of the methane gas in the Straw Gas, obtain the reforming gas of high heating value.The reforming gas of this high heating value is finished gas, liquid separation by gas-liquid separator again after condenser condenses, the gas part outputs to the adsorption cleaning device by gas path pipe, in the adsorption cleaning device, remove impurity components such as carbonic acid gas in the reforming gas, moisture, nitrogen, promptly obtain its major ingredient and be the high heating value Straw Gas of methane and a small amount of carbon monoxide, carbonic acid gas.The adsorption cleaning device is to the concentration of methane and carbon monoxide in the degree of treatment of the reforming gas decision gas, and then determines its calorific value size.Facts have proved that this device can bring up to the concentration of the methane gas in the Straw Gas degree more than 90%, calorific value can be by 2000Kcal/Nm
3About bring up to 5000～8500Kcal/Nm
3In addition, the big high heating value Straw Gas for a change of its component is because the improve of methane concentration, and hydrogen and carbon monoxide in the original Straw Gas have changed into methane, thereby eliminated the potential safety hazard when using, can incorporate city natural gas pipe network into and use, also can be made into CNG, LNC and use as natural gas.
This device can be made skid and move form, convenient transportation can be handled the efficiency height to the Straw Gas in the dispersive Straw Gas gasholder station, utilize become the to assign to methane of synthetic high heating value of low heat value in the Straw Gas to greatest extent, can be in the short period of time at the utmost point with the calorific value of Straw Gas by 2000Kcl/Nm
3About bring up to 5000～8500Kcl/Nm
3And self energy consumption is low---except that the compressor electricity consumption, the heat that the used thermal source of preheater produces in the time of can be by carbon monoxide and hydrogen reaction provides.Also having byproduct steam can do him in addition uses.
Below in conjunction with drawings and Examples content of the present utility model is done further and to be described in detail.
Fig. 1 is the structural representation of present embodiment
Embodiment
Referring to Fig. 1, the reforming apparatus of this raising Straw Gas calorific value is by compressor P1, preheater E1, E2, the convertor R1 of synthetic carbon monoxide and hydrogen, condenser E3, gas-liquid separator V1, by three adsorption tower T1, T2, T3 and sequence valve 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c, 5a, 5b, adsorption cleaning device and Straw Gas gas path pipe 1 that 5c constitutes, conversion gas gas path pipe 2 constitutes, wherein, Straw Gas gas path pipe 1 passes preheater E1, E2 is connected between compressor P1 outlet and the convertor R1 inlet, conversion gas gas path pipe 2 is to meet preheater E2 earlier from the convertor outlet in the present embodiment, the inlet that passes condenser E3 and gas-liquid separator V1 behind the E1 again joins, and the outlet from gas-liquid separator V1 connects adsorption cleaning device inlet again.The benefit of doing like this is the heat that preheater can be recycled convertor R1.Keeping of the temperature of reaction of convertor R1 can adopt the mode of boiler water circulation to realize as prior art.Adsorption cleaning device and sequence valve all can be continued to use existing installation.
The compressed machine P1 input of Straw Gas is input to after preheater E1, E2 are heated to temperature of reaction among the convertor R1, and carbon monoxide in the Straw Gas and hydrogen synthesize the methane gas of high heating value in convertor R1, thereby obtain the reforming gas of high heating value.The pyrolytic conversion gas that comes out from convertor R1 through preheater E2, E1 cooling, condenser E3 condensation after again by gas-liquid separator V1 finish gas, liquid separates; Gas partly outputs to the adsorption cleaning device, handles impurity components such as the carbonic acid gas removed in the reforming gas, moisture, nitrogen through the adsorption cleaning of routine, can obtain its major ingredient and be the high heating value Straw Gas of methane gas and a small amount of carbon monoxide, carbonic acid gas.
