Abstract
The invention discloses a methane safety pressure-limiting valve, which comprises a pressure-limiting exhaust pipe and an open container containing water, wherein one end of the pressure-limiting exhaust pipe is communicated with the methane chamber of a methane pool, and the other end of the pressure-limiting exhaust pipe extends to a place below the water surface in the open container; the methane chamber of the methane pool is communicated with the methane safety pressure-limiting valve; the methane pressure in the methane pool is limited by using the action of the water seal of the open container; when the methane pressure is within a control range, the methane is sealed under the action of the water seal; and when the methane pressure is overhigh and the water seal does not work, the methane escapes from the open container, so that the methane pressure in the pool is lowered, normal methane pressure is retained, and the safety hazards, such as blasting, caused by the overhigh methane pressure in the pool are prevented. In addition, the methane safety pressure-limiting valve can be mounted at a bottommost position of a methane pipe to collect the condensed water in the methane pipe, so water is supplied to the open container and the condensed water is prevented from flowing to a desulfurizer. The methane safety pressure-limiting valve can be made of waste plastic, the manufacture is simple, the cost is low, and the service life of the methane safety pressure-limiting valve is long.
Description
Technical field
The present invention relates to a kind of safety valve, be specifically related to a kind of biogas safety pressure-limiting valve.
Background technology
Methane-generating pit all should be installed safety valve, to prevent the too high security incidents such as blast that cause of biogas pressure in the pond, damages the equipment and the accessory of biogas.Existing safety valve all is a metal valve body, utilizes spring to regulate pressure, complicate fabrication process, and cost is higher, and because steam and sulphur are to corrosion of metal in the biogas, the life-span of safety valve is generally all shorter.
Therefore, need a kind of easy safety valve of design, can effectively limit the biogas pressure in the methane-generating pit, and make simply, cost is low, and the life-span is long.
Summary of the invention
In view of this, the invention provides a kind of biogas safety pressure-limiting valve, can effectively limit the biogas pressure in the methane-generating pit, and make simply, cost is low, and the life-span is long.
Biogas safety pressure-limiting valve of the present invention comprises pressure limiting vapor pipe and the open container that water is housed, and described pressure limiting vapor pipe one end is communicated with the gas dome of methane-generating pit, and the other end stretches into the underwater in the open container.
Further, the end that described pressure limiting vapor pipe stretches into open container is communicated with buffer container, has the air water flow passage on the buffer container, and described buffer container is packed in the open container;
Further, described air water flow passage is positioned at the buffer container bottom;
Further, described open container and buffering container are flask;
Further, described buffer container volume is an open container volumetrical 1/3rd to 1/2nd;
Further, described pressure limiting vapor pipe is communicated with biogas pneumatic tube bottom position.
Beneficial effect of the present invention is: the gas dome of methane-generating pit is communicated with the present invention, utilize the water seal of open container to be used for limiting the interior biogas pressure of methane-generating pit, when biogas pressure is in span of control, rely on the effect sealing biogas of water seal, when biogas pressure was excessive, water seal was lost efficacy, biogas is promptly overflowed from open container, reduce the biogas pressure in the pond, kept normal biogas pressure, prevented the too high security incidents such as blast that cause of biogas pressure in the pond; In addition, the present invention is installed in biogas pneumatic tube bottom position, can also collects the condensed water in the biogas pneumatic tube, both replenished water, prevented that again condensed water from entering devulcanizer to open container; The present invention can utilize waste and old Plastic Bottle to make, and makes simply, and cost is low, and the life-span is long.
Description of drawings
In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing, wherein:
Fig. 1 is a structural representation of the present invention.
Embodiment
Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.
Fig. 1 is a structural representation of the present invention, as shown in the figure, biogas safety pressure-limiting valve of the present invention comprises pressure limiting vapor pipe 1 and the open container 2 that water 3 is housed, described pressure limiting vapor pipe 1 one ends are communicated with the gas dome of methane-generating pit, and the other end stretches into the underwater in the open container 2; Utilize the water seal of open container 2 to be used for limiting the interior biogas pressure of methane-generating pit, when biogas pressure is in span of control, rely on the effect sealing biogas of water seal, when biogas pressure is excessive, water seal was lost efficacy, and biogas is promptly overflowed from open container 2, has reduced the biogas pressure in the pond, keep normal biogas pressure, prevented the too high security incidents such as blast that cause of biogas pressure in the pond.
As a further improvement on the present invention, the end that described pressure limiting vapor pipe 1 stretches into open container 2 is communicated with buffer container 4, has air water flow passage 5 on the buffer container 4, and described buffer container 4 is packed in the open container 2; Buffer container 4 is set, can increases water seal height, improve controlled biogas pressure; When biogas pressure rose, the water 3 in the buffer container 4 was discharged from air water flow passage 5, and buffer container 4 inside and outside water level pressure reduction increase, and after 3 emptyings of the water in the buffer container 4, biogas pressure continues to rise, and then water seal was lost efficacy, and biogas is promptly overflowed from open container 2; As need biogas pressure is controlled in a big way, then needs bigger buffer container 4 volumes, but for anti-sealing overflows from open container 2, described buffer container 4 volumes are open container 2 volumetrical 1/3rd to 1/2nd.
In the present embodiment, described air water flow passage 5 is positioned at buffer container 4 bottoms; The volume at air water flow passage 5 positions to buffer container 4 tops is the useful volume of buffer container 4, water in this useful volume could be discharged from air water flow passage 5 under the effect of biogas pressure, therefore, air water flow passage 5 is arranged at buffer container 4 bottoms, the useful volume maximum of buffer container 4.
In the present embodiment, described open container 2 and buffering container 4 are flask; Can utilize waste and old Plastic Bottle to make, as shown in the figure, the Plastic Bottle bottom of a 1.5L be removed, bottleneck seals with bottle stopper, promptly makes open container 2, with the Plastic Bottle bottom opening of a 500 ~ 650ml, bottleneck and pressure limiting vapor pipe 1 are tightly connected, and promptly make buffer container 4; Make simply, cost is low, and the life-span is long.
As a further improvement on the present invention, described pressure limiting vapor pipe 1 is communicated with biogas pneumatic tube bottom position; Can collect the condensed water in the biogas pneumatic tube, replenish water both for open container 2, prevent that again condensed water from entering devulcanizer.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although by invention has been described with reference to the preferred embodiments of the present invention, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
