Embodiment
Through specific embodiment the utility model is described in further detail below.
Shown in Figure of description 1; The positive negative pressure protector of a kind of biogas of the utility model; Comprise tank body and be positioned at jar intravital pressure stabilizing chamber 2, outer pressure stabilizing chamber 5 and voltage stabilizing water 8, interior pressure stabilizing chamber 2 is communicated with a jar interface 1, interior pressure stabilizing chamber 2 bottoms be connected with outer pressure stabilizing chamber 5 bottoms and the infraoral edge of outer pressure stabilizing chamber lower than the lower rim of jar interface 1; How many concrete ends change the level changing amplitude that causes according to the permission jar inside and outside differential pressure that designs and decide in; Voltage stabilizing water 8 is positioned at pressure stabilizing chamber 2 isolates pressure stabilizing chamber and outer pressure stabilizing chamber with outer pressure stabilizing chamber 5 bottoms, and said outer pressure stabilizing chamber 5 is through vapor pipe 13 and atmosphere, to improve the firedamp drainage height.The position of voltage stabilizing water in interior pressure stabilizing chamber 2 is interior water level 3, and the voltage stabilizing water position in the pressure stabilizing chamber outside is outer water level 6.
Interior pressure stabilizing chamber and pressure stabilizing chamber also can be two pipelines that are arranged side by side or cylinder body constitutes, and the bottom is communicated with through pipe or another big tank body.The positive negative pressure protector of present embodiment adopts an out cylinder and an inner cylinder that is inserted in the out cylinder to form, and the inner cylinder upper space constitutes outer pressure stabilizing chamber 5, pressure stabilizing chamber 2 in the space formation between inner cylinder and the out cylinder is said; This structure is not only compact; And outward appearance has only an out cylinder, simple appearance, and it is little to take up room; The few leakage point of exposed weld seam is few, safe.
Usually biogas jar internal pressure is higher than the interior interior water level 4 of pressure stabilizing chamber in the outer water levels 6 in the pressure stabilizing chamber 5 are higher than beyond the barometric point institute 2, and it is poor that the static pressure of this waterhead is biogas jar external and internal pressure.Interior water level 4 in when the jar internal pressure increases in the pressure stabilizing chamber descends; Outer water level 6 in the outer pressure stabilizing chamber 5 rises; And a jar internal pressure be elevated in water level when reaching outer pressure stabilizing chamber infraoral edge; The interior gas of jar can get into outer pressure stabilizing chamber and pass through exhaust with pressure release, realizes that positive pressure protection prevents the danger that superpressure causes.When otherwise a jar internal pressure is lower than barometric point formation negative pressure; The interior water level 4 outer water level 6 that rises drops to and is lower than interior water level; When interior water level 6 drops to outer pressure stabilizing chamber bottom, thereby extraneous air can enter into interior pressure stabilizing chamber 4 tonifying Qi in the biogas jar, with the danger of avoiding negative pressure to cause.Thereby reach the effect of positive negative pressure protection.
Interior pressure stabilizing chamber 2 inside are provided with inner waterproofing baffle plate 4 near jar interface 1 place, and inner waterproofing baffle plate 4 effect is that a jar internal pressure crosses low extraneous air and in jar, during air inlet, prevent that voltage stabilizing water 8 from being advanced in the digester by the air-flow splash.Be provided with outer water bar 7 above the outer water level 6 of outer pressure stabilizing chamber 5; Outer water bar 7 be positioned at vapor pipe 13 below; Said outer water bar 7 is positioned at the mouth of pipe of the following and area of vapor pipe greater than vapor pipe 13, is that air-flow is gone out outer pressure stabilizing chamber 5 with water when preventing jar interior superpressure pressure release.Be provided with waterproof cover 14 above the vapor pipe 13, can the waterproof dust protection.
The positive negative pressure protector of biogas also comprises tensimeter 9 and water level gauge 11, and the interior water level 3 of pressure stabilizing chamber 2 was with top in tensimeter 9 was connected, and water level gauge 11 is a glass-tube liquid level meter, and its underpart is communicated with water level gauge top and atmosphere with voltage stabilizing water 8 in the interior pressure stabilizing chamber 2.Since interior pressure stabilizing chamber 2 with jar in be communicated with, so the pressure of tensimeter 9 promptly reacts is biogas jar internal pressure, and water level gauge 11 liquid levels and outer pressure stabilizing chamber outward water level 6 remain consistent.
There is scale on the surface of general water level gauge 11, and what this scale showed is the elevation of water surface value.Voltage stabilizing water 8 in use has evaporation, thereby water level descends with outer water level in causing, and voltage stabilizing water can cause positive negative pressure protection inefficacy when being lower than a certain limit value.Whether yet water level gauge 11 reaction is the outer water level 6 of simple outer pressure stabilizing chamber 5, and this water level changes with the jar internal pressure, can not the actual response voltage stabilizing water water yield too low.Though outer pressure stabilizing chamber water level gauge can be installed, calculate the amount of total voltage stabilizing water 8 through calculating, because the difference of operator's educational level is not that everybody can calculate, and reaction is not directly perceived yet.
There is the level pressure scale on the surface of the utility model water level gauge 11, and the upper end of water level gauge is provided with water supplement port 10, and the lower end is provided with water drain valve 12.Be engraved on the water level gauge 11 through being converted into elevation of water surface force value; Therefore scale value and the manometric reading basically identical on water level gauge 11 just often; When voltage stabilizing water during because of the evaporation lack of water, even a jar internal pressure remains unchanged, interior water level all can descend with outer water level; The pressure reading that shows on build-up of pressure table 9 and the water level gauge 11 is inconsistent, and promptly the registration that reads out of water level gauge is lower than tensimeter.Therefore can go out the peak and the minimum value of the fair meter of the voltage stabilizing water water yield according to design calculation; The pressure that water level gauge shows when being lower than minimum value and the difference of tensimeter pressure are the lack of water ultimate value;, operator just are lack of water when finding that both reading differences reach this limit difference; Need moisturizing, otherwise be water to a certain degree the time greater than the tensimeter display digit excessive when the water level gauge numeral, need discharge water.Therefore operator only need know that water level gauge and the difference that the tensimeter registration allows get final product, through judging whether lack of water and whether moisturizing is excessive with contrasting convenient reading.
During the difference of altitude of water level and interior water level produces outside the gaseous tension in the digester adds greater than barometric point pressure, gas will be run out of from vapor pipe through voltage stabilizing water in the digester, make the pressure-stabilisation in the digester.During the difference of altitude of water level and interior water level produces outside the gaseous tension in the digester adds less than barometric point pressure; To from atmosphere, suck air in the digester; Keep the pressure-stabilisation in the digester, thereby protection biogas digester is not destroyed because of superpressure or low pressure.
