The specific embodiment
The utility model is the combination product that is combined into one with the three-way connection 10 of biogas ceramic valve 16, U-shaped cylinder for desulfurization 14, carry sample chamber 30 and Pressure gauge 9.
Cylinder for desulfurization 14, biogas porcelain core valve 16, three-way connection 10 all are fixed on the drain pan 6, and Pressure gauge 9 is packed on the drain pan 6 through stator 7.Panel 8 covers to be contained in and constitutes the marsh gas purifying pressure regulator that the desulfurization of this band shows on the drain pan 6.Covering 11 places in the demonstration of three-way connection 10 on the panel 8 has emptying aperture, shows the desulfurizing agent 15 that covers sample room 30 in 11 in order to observe.There is emptying aperture to be used to observe the surface of Pressure gauge 9 on the panel 8, so that read the biogas pressure number.
Biogas porcelain core valve 6 is packed in an example of cylinder for desulfurization 14, valve body 25 on it has biogas air inlet pipe joint 21 and biogas escape pipe joint 22, it is identical at the inner chamber of valve body 25 two chip architectures to be housed, folded mutually leaning on, and the ceramic valve core 18 that can be in relative rotation respectively constitutes with the potsherd of two symmetrical holes 32, for anti-gas-leak is equipped with sealing ring 29.One end roof pressure ceramic valve core 18 of valve rod 26, valve rod 26 other ends are set with spring 28 and valve gap 27, valve gap 27 top pressure springs 28, and spinning connection valve body 25, knob 17 is contained in the termination of valve rod 26.
Three-way connection 10 has three pipe joints, it is respectively biogas discharge conection 34, pressure-measuring pipe joint 23 and tube connector joint 31, it is the sample room 30 of dress desulfurizing agent 15 that three-way connection 10 has inner chamber, transparent demonstration lid 11 covers in the sample room 30 end face, is convenient to the behaviour in service of desulfurizing agents 15 in user's observation sample chamber 30.Be anti-gas-leak, show that cover 11 is added with little sealing gasket 12 when covering.
U-shaped cylinder for desulfurization 14 is the connection tubulose that takes the shape of the letter U, two bodies are arranged and at the bottom of bottle, be connected, a bottleneck pipe 19 is respectively arranged on two bodies, cover 1 with pipe during use and cover,, sealing gasket 2 is housed for preventing gas leakage, at the bottom of bottle, be communicated with the bottom, position a bottle bottom tube 20 is arranged, also cover 1 during use and cover, be anti-gas-leak, sealing gasket 2 is housed with pipe.On two bodies top an interface tube 33 is arranged all, they connect a termination of input tube connector 5 and output tube connector 13 respectively, at the fixing barrier board 3 of interface tube 33 useful foam double-side glue 4 sticking dresses, the desulfurizing agent 15 that is equipped with when preventing to use is fallen into the obstruction that tube connector causes tube connector, influences the circulation of biogas.The other end of input tube connector 5 connects the biogas escape pipe joint 22 of biogas porcelain core valve 16.Output tube connector 13 other ends connect the tube connector joint 31 of three-way connection 10.
Pressure-measuring pipe 24 two ends connect the pressure-measuring pipe joint 23 of Pressure gauge 9 and three-way connection 10 respectively.
Biogas air inlet pipe joint 21 of the present utility model, biogas escape pipe joint 22, tube connector joint 31 are identical with biogas discharge conection 34 structures.The biogas air inlet pipe joint 21 and the biogas discharge conection 34 of combination product all are arranged on lower part of frame, the installation appearance and size of its biogas porcelain core valve 16 and three-way connection 10 is consistent, can conveniently exchange, when being convenient to install according to the field condition of user's biogas approach axis, select for use matched into and out of the biogas position, do not need to make when mounted the biogas pipeline of input, output to intersect, the convenient installation, it is succinct, attractive in appearance that pipeline is installed.
When the marsh gas purifying pressure regulator that the band desulfurization shows uses, open the pipe lid 1 of the bottleneck pipe 19 of cylinder for desulfurization 14 earlier, pipe lid 1 lid of the bottle bottom tube 20 of position, junction at the bottom of the bottle is tight, desulfurizing agent 15 (is for example used Fe
2O
3) in the cylinder for desulfurization 14 of packing into, and simultaneously the demonstration lid 11 of three-way connection 10 is opened, desulfurizing agent 15 (is for example used Fe
2O
3) sample puts in the sample room 30, to manage then and cover 1 and show and cover 11 lids tightly, the biogas that biogas generating device is produced is delivered to this device connection biogas air inlet pipe joint 21 with pipeline, biogas promptly flows in the cylinder for desulfurization 14 along input tube connector 5 through 16 pressure regulation of biogas porcelain core valve, biogas flows in desulfurizing agent 15, behind most sulfide in the 15 absorption biogas of desulfurizing agent in the cylinder for desulfurization 14, biogas is along output tube connector 13 and tube connector joint 31 three-way connection 10 of flowing through, biogas flows through sample room 30 and biogas is delivered to Pressure gauge 9 demonstration biogas pressures through pressure-measuring pipe joint 23 and pressure-measuring pipe 24, biogas flows out for using from biogas discharge conection 34, be delivered to methane cooker with the pipeline connection, biogas water heater and biogas lamp are lighted use.Because sulfide is got rid of in a large number in the biogas, content of sulfur dioxide is extremely low in its combustion gas waste gas, meets the environmental requirement regulation, safety and non-pollution discharge waste gas.Sample room 30 is arranged in three-way connection 10, put in the sample room and the cylinder for desulfurization 14 crowd desulfurizing agent Fe that puts into simultaneously together
2O
3When biogas entered cylinder for desulfurization 14 and sample room 30, biogas contacted with desulfurizing agent 15, and the sulfide in the biogas is desulfurized agent adsorption reaction, Fe
2O
3Be converted into iron sulfide, the blackening gradually of desulfurizing agent 15 surface colors, people are by showing that cover 11 transparent cover plate is the available desulfurizing agent color sample situation of change of examining in the sample room 30 of three-way connection 10 of observing, when particle surface all becomes black, promptly showing needs desulfurizing agent is regenerated or changed, and when be convenient to user's exact grasp needs regeneration or replacing desulfurizing agent.Fundamentally solve current desulfurizing agent because of not having the lid of demonstration and sample room, caused the rural area users can't grasp the difficulty of the behaviour in service of understanding desulfurizing agent.When the user need change desulfurizing agent 15, only three pipes of cylinder for desulfurization 14 need be covered 1 turns on, desulfurizing agent 15 promptly falls down from the mouth of pipe of bottle bottom tube 20, simultaneously the demonstration lid 11 of sample room 30 is turned on, take out the desulfurizing agent sample, when the desulfurizing agent 15 of packing into new, lid 1 lid of bottle bottom tube 20 is tight, new desulfurizing agent 15 is poured in the bottle from two bottleneck pipes 19, and after desulfurizing agent 15 was filled, it was tight to cover 1 lid, put new desulfurizing agent 15 into sample room 30 simultaneously, to show and cover 11 lids tightly, desulfurizing agent 15 is changed fast and is finished, and can come into operation.
Accompanying drawing 4 expression biogas porcelain core valves 16 in off position.Two potsherds that circle is with holes of ceramic valve core 18, under knob 17 rotating operations, two blocks of potsherds relatively rotate, after two potsherd transpositions, both holes that is used to flow through biogas are sealed mutually, biogas porcelain core valve 16 is in closed condition, and biogas can not flow through this valve and enter in the cylinder for desulfurization 14, does not also have biogas output at the biogas out splice going splice 34 of three-way connection 10.
