Fostering energetically down of country; rural development the methane station of a lot of green energy resources; stalk with the rural area; feces of livestock and poultry changes into biogas and uses for the peasant; turn waste into wealth; benefit the nation and the people; one of equipment of most critical is digester in the methane station; the inherent run duration of digester can produce a large amount of biogas, and biogas can make the air pressure in the digester change; simultaneously; along with charging; discharging; operational processs such as spoil disposal also can make the gaseous tension in the digester constantly change, and influence the production safety of digester; therefore, setting up positive negative pressure protection on digester is very important.
At present, the positive negative pressure protector of digester mainly contains following 2 kinds of modes:
(1) positive pressure protection device and negative pressure protector are set respectively at the digester top.The positive pressure protection device is to utilize less caliber to be deep in the big caliber; there are a certain amount of water level such as Fig. 1 tubule footpath directly to be connected in the big caliber with digester top; when the gaseous tension in the digester during greater than the protection force value of positive pressure protection device; gas will be run out of from the positive pressure protection device in the digester, make the pressure-stabilisation in the digester.The negative pressure protector is that the promptly big caliber of the anti-dressing of positive pressure protection device is connected with digester; when the gaseous tension in the digester during less than the protection force value of positive pressure protection device; to suck air from the positive pressure protection device in the digester, thereby reach the pressure-stabilisation in the protection digester.
(2) integrated positive negative pressure protector; just a protector can protect malleation also can protect negative pressure; the technology of the positive integrated protector most critical of negative pressure is to be incompressible this ABC based on water under the relative temperature; the ratio that draws the positive negative pressure of a digestive organ protection equals interior ratio of pressing the external pressure area; according to this rule, just can produce the incorporate protector of positive negative pressure.
The utility model content
The purpose of this utility model is to provide a kind of new positive negative pressure protector, owing to be integrated, therefore, it saves material more, and structure is simpler, and is more economical.Because the height of its big tubule is equal to the positive/negative pressure value, therefore, it is safer, superpressure may be lower with getting.Because its positive negative pressure all has equalization chamber, therefore, its voltage stabilizing water can not be flushed away because of superpressure.
The utility model adopts following technical scheme: a kind of new integrated positive negative pressure protector, its ultimate principle is to utilize incompressible this characteristic of water, develops.Integrated positive negative pressure protector comprises interior pressure stabilizing chamber; outer pressure stabilizing chamber; interior pipe; outer tube; water level gauge; voltage stabilizing water; outer pressure stabilizing chamber is above outer tube is vertical; outer pressure stabilizing chamber width must be bigger than outer tube diameter; there is rain-proof cover outer pressure stabilizing chamber upper end; cover and establish return flume; its position is corresponding with outer tube; outer pressure stabilizing chamber leads directly to atmosphere; interior pressure stabilizing chamber is above interior pipe is vertical; interior pressure stabilizing chamber width must be bigger than diameter of inner pipe; the straight-through digester in interior pressure stabilizing chamber upper end; there is a directional valve water level gauge upper end, and there are two interfaces the upper end of directional valve, and an interface is to receive outer pressure stabilizing chamber; another receives interior pressure stabilizing chamber, and directional valve is communicated with outer pressure stabilizing chamber or interior pressure stabilizing chamber respectively by directional valve lower end water level gauge water level by moving valve handle.
1, inner and outer pipes: pipe highly equaled negative pressure value in 1) we can artificially stipulate, the external pressure tube height equals the malleation value; 2) according to incompressible this principle of water, pipe voltage stabilizing volume of water equals external pressure tube voltage stabilizing volume of water in allowing, and determines the caliber of outer tube, can draw inner tube diameter.
2, inside and outside pressure stabilizing chamber: the purpose that pressure stabilizing chamber is set is when positive and negative superpressure, and voltage stabilizing water is stayed in the pressure stabilizing chamber, and causes the gas of superpressure to stablize discharge in pressure stabilizing chamber.Interior pressure stabilizing chamber needn't specially be made, because outer tube than interior pipe height, forms an interior pressure stabilizing chamber naturally in the positive negative pressure protector.Outer pressure stabilizing chamber can suitably be increased the outer sleeve of positive negative pressure protector, thereby forms an outer pressure stabilizing chamber.
3, water level gauge: 1), in integrated positive negative pressure protector, two water levels are arranged because digester has certain air pressure, interior water level and outer water level, interior water level is the relative pressure of digester with the difference of outer water level.2) in general water level gauge, or be interior water level, or be outer water level, can't understand the pressure reduction in the digester.Have only this novel water level gauge, just can determine the pressure reduction of digester, the more important thing is that simultaneously this water level gauge can also determine whether lack of water of water level gauge oneself itself.3) its principle is the level scale of water level gauge, and outer water level digital calibration makes progress away from 0, and interior water level digital calibration is walked downwards from 0, and the ratio of scale spacing that makes progress and downward scale spacing equals the ratio of outer tube height and interior pipe height.Under the situation of lack of water not, no matter inside and outside water level somewhere, its numeral on water level gauge is one to one.As lack of water, inside and outside water level is all descended, the numeral on the water level gauge just has deviation, can learn by its deviate lack of water is how much.4) how to measure its inside and outside water level? most critical be exactly that water level gauge upper end has a directional valve, there are two interfaces the upper end of directional valve, an interface is to receive outer pressure stabilizing chamber, another receives interior pressure stabilizing chamber, directional valve is communicated with outer pressure stabilizing chamber or interior pressure stabilizing chamber respectively by directional valve lower end water level gauge water level by moving valve handle, thereby draws the force value of inside and outside pressure stabilizing chamber and pressure reduction and lack of water whether.
4, voltage stabilizing water: at the voltage stabilizing water of in the past positive negative pressure protector is exactly that common tap water is with salt; with salt or use bath of glass; purpose is to make the slow and preventing freeze in winter of water evaporable; and novel voltage stabilizing water adds liquid machine oil on this basis; liquid machine oil proportion is lighter than water; it swims on the water surface, can prevent the volatilization of voltage stabilizing water effectively.
