Abstract
The utility model relates to a gas collecting hood device of a methane generating pit, which consists of a gas collecting hood, an inner water storage ring and an outer water storage ring and is characterized in that the distance between the inner wall of the gas collecting hood and the outer wall of the inner water storage ring is larger than the distance between the inner wall of the outer water storage ring and the outer wall of the gas collecting hood; the upper part of the gas collecting hood is provided with a vent pipe communicated with a ground methane pressure gauge; the outer water storage ring is provided with a water inlet pipe connected with a ground tap water pipe; and the vent pipe also has an effect of an overflow port by holes of the outer water storage ring. The device is used on the concrete structural methane generating pit and has obvious effects that the device is convenient to manage and use; water is evaporated slowly; and the methane leakage is prevented for a long time.
Description
Affiliated technical field
The utility model relates to a kind of interior retaining circle height problem of methane-generating pit gas skirt device, especially methane-generating pit gas skirt.
Background technology
Existing process with plastics or matrix material or metal; The tank that the gas skirt that is installed on the methane-generating pit top has the retaining circle to form inside and outside being, gas skirt is at the middle part of tank, and interior retaining circle height is 1/2nd of a gas skirt; Outer retaining circle is slightly higher than gas skirt, and gas tube is installed on the gas skirt top.China's utility model patent numbers 200920153323.9; " a kind of inversion gas tube of biogas fermentation device " with the side of gas tube upside-down mounting in the gas skirt below, makes gas pipe line all embedding underground; Both make the gas skirt conveniently opening and closing, can prolong gas pipe line work-ing life again.But to be gas skirt high that half is too high for the interior retaining circle height in the above-mentioned gas skirt, is unfavorable in methane-generating pit top and methane-generating pit skylight opening operation up and down.
Summary of the invention
Too high in order to overcome in the existing gas skirt retaining circle, be unfavorable for the defective of methane-generating pit skylight opening operation, the utility model provide a kind of in the shorter gas skirt device of retaining circle.
The utility model solves the technical scheme that its technical problem adopted: comprise gas skirt, interior retaining circle, outer retaining circle, gas skirt inwall and interior retaining ring outer wall distance are greater than the distance of outer retaining circle inwall and gas skirt outer wall.Like this, because interior tank plane is long-pending long-pending greater than the external flume plane, also can adapt to the requirement of methane-generating pit pressure design though interior retaining circle is short.
The ventpipe that connects with ground biogas pressure epiphase is equipped with at the gas skirt top of methane-generating pit on the ground, and outer retaining circle is equipped with the water inlet pipe that links to each other with the ground running water pipe, and ventpipe has the effect of riser concurrently through the hole of outer retaining circle.
Open and close for ease and reduce cost, gas skirt is generally all processed shell shape, lighter weight; Floating for preventing gas skirt by the air pressure top; Two to four iron hoops are equipped with at retaining circle top outside, penetrate iron hoop with one to two depression bar two ends, between depression bar and the gas skirt cushion block are arranged.
The beneficial effect of the utility model is: interior retaining circle height reduction helps reducing outer retaining circle moisture evaporation face in methane-generating pit top and the operation of turnover skylight opening, and retaining circle cost in reducing is convenient to interior retaining circle and is installed.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the plat of the utility model.
Fig. 2 is the I-I sectional view of Fig. 1.
1 outer retaining circle among the figure, 2 water inlet pipes, 3 gas tubes, 4 gas skirts, 5 depression bars, 6 iron hoops, 7 handles, 8 cushion blocks, 9 ventpipes, 10 interior retaining circles.
Embodiment
In Fig. 1, Fig. 2, comprise gas skirt (4), interior retaining circle (10), outer retaining circle (1), gas skirt (4) inwall and interior retaining circle (10) outer wall distance are greater than the distance of outer retaining circle (1) inwall and gas skirt (4) outer wall.
The ventpipe (9) that is communicated with ground biogas pressure epiphase is equipped with at gas skirt (4) top; The water inlet pipe (2) that links to each other with the ground running water pipe is equipped with on outer retaining circle (1) top; Ventpipe (9) has the effect of riser concurrently through the hole of outer retaining circle (1), to go up the use and management of methane-generating pit to gas skirt (4) easily.
There are two to four iron hoops (6) on outer retaining circle (1) top, penetrates iron hoop (6) with one to two depression bar (5) two ends, between depression bar (5) and gas skirt (4) top cushion block (8) is arranged.
Claims (3)
1. a methane-generating pit gas skirt device comprises gas skirt, interior retaining circle, outer retaining circle, it is characterized in that the distance of gas skirt inwall and interior retaining ring outer wall distance greater than outer retaining circle inwall and gas skirt outer wall.
2. methane-generating pit gas skirt device as claimed in claim 1; It is characterized in that said gas skirt top is equipped with the ventpipe that is communicated with ground biogas pressure epiphase; The water service pipe that links to each other with the ground running water pipe is equipped with on outer retaining circle top, and ventpipe has the effect of riser concurrently through the hole of outer retaining circle.
3. methane-generating pit gas skirt device as claimed in claim 2 is characterized in that there are two to four iron hoops on said outer retaining circle top, penetrates iron hoop with one to two depression bar two ends, between depression bar and the gas skirt top cushion block is arranged.
