Summary of the invention
The purpose of this utility model is to provide a kind of device from extraction purifying methane and carbon dioxide biogas impurity, can improve biogas composition cumulative efficiency, improves the DNA purity of composition.
The utility model is achieved through the following technical solutions.
A kind of from biogas impurity, extracting the device of purifying methane and carbon dioxide, it is characterized in that: described device from extraction purifying methane and carbon dioxide biogas impurity comprises cooling device, separation chamber, the methane gas cylinder, dioxide bottle and pipeline, the pipeline front end is provided with inlet valve, rear end is provided with outlet valve and pressure vacuum gauge, separation chamber is placed in cooling device, separation chamber also is equipped with heater, separation chamber is connected to the inlet valve of pipeline and the line segments between outlet valve, between separation chamber and pipeline, be provided with the 3rd air valve, the methane gas cylinder is connected with methane and advances a bottle pipeline, at methane, advance on bottle pipeline to be provided with the first air valve, dioxide bottle is connected with carbon dioxide and advances a bottle pipeline, at carbon dioxide, advance on bottle pipeline to be provided with the second air valve, methane advances bottle pipeline and is communicated with the bottom of separation chamber, carbon dioxide advances bottle pipeline and is communicated with the top of separation chamber, leading to separation chamber, the methane gas cylinder, on the pipeline of dioxide bottle, also be respectively equipped with the pressure gauge of using for adjustable pressure.
Described cooling device comprises Dewar bottle, and separation chamber is placed in Dewar bottle, in Dewar bottle, fills cold-producing medium.
Described carbon dioxide advances bottle pipeline and is connected with pipeline, and the methane gas cylinder also is connected with pipeline, between methane gas cylinder and pipeline, is provided with the 5th air valve.
The air gauge of display bottle internal pressure all is installed on described methane gas cylinder, dioxide bottle.
Described rear end of pipeline is connected with vacuum extractor, before outlet valve is located at vacuum extractor.
Described separation chamber also adds thermocouple assembly.
The utility model compared with prior art has the following advantages.
By structure described in the utility model, make from biogas impurity, extracting the method that the purifying methane and carbon dioxide is pure methane and pure carbon dioxide, adopt new execution sequence, thereby improved biogas composition cumulative efficiency.Solved the problem that solid-state biogas condensation is warmed to indoor temperature.By structure described in the utility model, implementation be that composition separates simultaneously, so the efficiency of composition accumulation can reach maximum.In addition, can extract highly purified composition, each biogas component separation quantity is no more than 0.8 V C, constituent concentration in V-biogas condensation volume, C-biogas.Because when solid-state biogas is heated to room temperature, because the steam elasticity of methane and carbon dioxide there are differences, in forming the pure gas composition of separating interface, carry out the biogas separation, separate the pressure of biogas by tens Atmospheric compositions, higher for the known method possibility of next step separation collection high concentrations of gas Capacity Ratio like this, for the composition accumulation provides higher efficiency, and, when composition separates simultaneously, not there will be the phenomenon that gas mixes and container fills up when high pressure: on the one hand, guarantee the high efficiency accumulation; Accumulate on the other hand the high-purity composition.If no more than 0.8 VC of each component separation quantity of biogas, the situation of mixing is can not occur, and this has also determined the high-purity of accumulation composition.
The accompanying drawing explanation
Fig. 1 is that the utility model is from extracting the cup shell assembly structural representation of the device of purifying methane and carbon dioxide biogas impurity.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail from the device that extracts the purifying methane and carbon dioxide biogas impurity.
