Description
Technical field
The utility model relates to the security device of anaerobic fermentation equipment in the big-and-middle-sized biogas engineering, especially a kind of positive negative pressure safety means of anaerobic fermentation tank.
Background technology
Big-and-middle-sized biogas engineering is one of important means that solves the energy and problem of environmental pollution; in the existing big-and-middle-sized biogas engineering; the use of steel anti-corrosive type anaerobic fermentation tank is more and more general; in the use of anaerobic fermentation tank; because misoperation or damage regular meetings such as equipment, pipeline cause anaerobic fermentation tank problems such as biogas excessive (superpressure transfinites), negative pressure to occur; these problems cause the distortion and the damage of anaerobic fermentation tank easily, thereby anaerobic fermentation tank will dispose suitable positive negative pressure safety means.Though the positive negative pressure safety means of other pattern of domestic existence, there are the following problems:
1, adopts the negative pressure of vacuum safety valve.Because the negative pressure of vacuum safety valve can only be moved under anaerobic fermentation tank produces the situation of negative pressure, and during the anaerobic fermentation tank superpressure, the negative pressure of vacuum safety valve can't start, so can't guarantee the safety of anaerobic fermentation tank under the superpressure situation.And negative pressure of vacuum safety valve price is higher, has increased the input of biogas engineering.
2, adopt positive negative pressure relief valve.Because it is higher that conventional positive negative pressure relief valve moves needed pressure, and anaerobic fermentation tank is because barrel diameter, the tank deck area is bigger thereby stressed big, conventional positive negative pressure relief valve can only under lower positive condition of negative pressure, move, so can't satisfy the needs of anaerobic fermentation tank.
3, owing to contain corrosive gasess such as hydrogen sulfide, carbonic acid gas in the biogas, elements such as the spring in the conventional positive negative pressure relief valve, valve block are corroded easily and lost efficacy, and bring new hidden danger for the safe operation of anaerobic fermentation tank.
Summary of the invention
The purpose of this utility model provides a kind of anaerobic fermentation tank security device, with solve anaerobic fermentation tank bear superpressure, transfinite, safety problem under the negative pressure condition.
The purpose of this utility model realizes by following technical proposal:
A kind of anaerobic fermentation tank security device, mainly comprise vapor pipe, sealed tube, outer tube, sealing plug, guide rod, saddle, stay cord, diaphragm and communicating pipe, it is characterized in that anaerobic fermentation tank inside is provided with sealed tube, the sealed tube lower end is communicated with the vapor pipe that passes the anaerobically fermenting tank skin, the sealed tube wall periphery is connected with the outer tube that is higher than sealed tube, outer tube epimere arranged transversely saddle, the saddle middle part has and the guide rod shape of cross section, the hole that size matches, guide rod vertically passes the hole, lower end of the guide rod is provided with the sealing plug that fits with sealed tube, the guide rod upper end connects stay cord, the other end of stay cord connects diaphragm, diaphragm is fixed on the lower end of communicating pipe, is arranged on communicating pipe on the anaerobic fermentation tank tank deck and with the external world to communicate.
The beneficial effects of the utility model:
Anaerobic fermentation tank security device of the present utility model is simple in structure, easy to make, long service life, maintenance is easy, cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, vapor pipe; 2, sealed tube; 3, outer tube; 4, sealing plug; 5, guide rod; 6, saddle; 7, stay cord; 8, diaphragm; 9, communicating pipe; 10, tank deck; 11, hole.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, anaerobic fermentation tank security device of the present utility model mainly comprises vapor pipe 1, sealed tube 2, outer tube 3, sealing plug 4, guide rod 5, saddle 6, stay cord 7, diaphragm 8 and communicating pipe 9.Vapor pipe 1 preferred carbon steel or the stainless-steel pipe of adopting made.Preferred corrosion resistant rubber, the plastic materials of adopting of sealing plug 4 are made, and one has solved anticorrosive problem, and two because plastics, rubber are soft, can effectively guarantee and the contacting and sealing of sealed tube section.Sealed tube 2, outer tube 3, guide rod 5 and the saddle 6 preferred high-quality stainless steel tubes that adopt are made, can withstand long term exposure biogas in the corrosion of corrosive gases.The stay cord 7 preferred nylon materials with certain retractility that adopt are made, and guaranteeing also have certain toughness under the tolerance corrosive situation, have guaranteed intensity.Diaphragm 8 preferred employing snappy rubber diaphragms, but the withstand long term exposure corrosion also can deform along with the variation of pressure and restore.
Anaerobic fermentation tank inside is provided with sealed tube 2, sealed tube 2 lower ends are communicated with the vapor pipe 1 that passes the anaerobically fermenting tank skin, the sealed tube wall periphery is connected with the outer tube 3 that is higher than sealed tube 2, outer tube 3 epimere arranged transversely saddles 6, saddle 6 middle parts have the hole 11 of matching with guide rod 5 shape of cross sections, size, guide rod 5 vertically passes hole 11, and the movement locus that hole 11 defines guide rod 5 makes it and can only move up and down.Guide rod 5 lower ends are provided with the sealing plug 4 that fits with sealed tube 2, and under the normal circumstances, sealing plug 4 lower ends and sealed tube 2 upper ends fit tightly, and guarantee that gas does not leak in the anaerobic fermentation tank.Guide rod 5 upper ends connect stay cord 7, and the other end of stay cord 7 connects diaphragm 8, and diaphragm 8 is fixed on the lower end of communicating pipe 9, and communicating pipe 9 is arranged on the anaerobic fermentation tank tank deck 10 and with the external world and communicates.
Groundwork principle of the present utility model is:
When the anaerobic fermentation tank internal gas pressure raises, diaphragm 8 is upwards heaved by gas pressure, thereby pulling stay cord 7, stay cord 7 pulling sealing plugs 4 move up, make between sealing plug 4 and the sealed tube 2 and form the slit, unnecessary gas is then discharged outside the anaerobic fermentation tank by slit and vapor pipe 1, thereby guarantees the pressure equilibrium of anaerobic fermentation tank.
When negative pressure occurring in the anaerobic fermentation tank, because sealed tube 2 is in communication with the outside with vapor pipe 1, extraneous normal atmosphere acts on sealing plug 4, makes between sealing plug 4 and the sealed tube 2 and forms the slit, extraneous air enters anaerobic fermentation tank by the slit, thereby guarantees the pressure equilibrium of anaerobic fermentation tank.
