Alternatively, also including by water replanishing device from the protection pipe to the tank body moisturizing.
The utility model provides a kind of marsh-gas fermentation tank, includes protection pipe, tank are fixedly installed on the tank body of sealing, tank body
The other parts sealing of body, is connected by protection pipe with external world's holding.Fermentation liquid level is stretched into the end that protection pipe is located in tank body
Hereinafter, ambient atmos are kept mutually to completely cut off with tank interior gas by fermented liquid.The top of protection pipe and fermentation liquid level
Vertical height determines that the depth of fermentation liquid level is stretched into according to the determination of negative pressure protection value in the bottom of protection pipe according to positive pressure protection value.
When the air pressure of tank interior exceedes negative pressure protection value, air pressure inside is too low, and extraneous gas can pass through protection pipe
Tank interior is entered, make-up gas improves air pressure, it is to avoid the pressure in tank body is persistently reduced, play negative pressure protection and act on.
When the air pressure of tank interior exceedes positive pressure protection value, internal air pressure is too high, the liquid of tank interior can by protection pipe to
Outer discharge, fermentation liquid level is reduced to below protection pipe, and inside and outside gas is interconnected, and internal gas is discharged, inside reduction
Air pressure, plays positive pressure protection.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
The structural representation for the marsh-gas fermentation tank that Fig. 1 provides for the utility model.
Including：
Tank body 1, protection pipe 2.
Embodiment
Core of the present utility model is to provide a kind of marsh-gas fermentation tank, and positive pressure protection can be played simultaneously and negative pressure is protected
Shield, it is to avoid the pressure abnormity in tank body.
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with accompanying drawing and
Specific embodiment, explanation is described in detail to the marsh-gas fermentation tank of the application.
As shown in figure 1, the structural representation of the marsh-gas fermentation tank provided for the utility model.The marsh-gas fermentation tank, including
The tank body 1 of sealing, with extraneous mutually isolation, internally creates suitable fermentation condition, produces biogas.It is fixedly installed on tank body 1
The protection pipe 2 that can be in communication with the outside.One end of protection pipe 2 is in tank body, and the other end is outside tank body, and protection pipe 2 is located at tank body 1
Interior end is stretched into below fermentation liquid level, and protection pipe 2 keeps sealing state by fermented liquid, and tank is kept in the state of normal
Gas inside body 1 is sealed with extraneous mutually isolation.
The top of protection pipe 2 and the vertical height of fermentation liquid level determine that the bottom of protection pipe 2 is stretched into according to positive pressure protection value
The depth of fermentation liquid level is determined according to negative pressure protection value.The principle of work is, when the atmospheric pressure value in tank body 1 is persistently reduced, to be less than
During negative pressure protection value, extraneous air pressure is more than internal air pressure, and extraneous air pressure declines the liquid level of protection pipe 2, final extraneous
Gas can enter the inside of tank body 1, supplement the atmospheric pressure value inside air, lifting tank body 1, serve negative pressure protective effect.
When the atmospheric pressure value in tank body 1 is persistently raised, during higher than positive pressure protection value, internal air pressure is more than extraneous air pressure, internal gas
Pressure rises the liquid level of protection pipe 2, eventually discharges zymotic fluid, after a certain amount of liquid is discharged, under fermentation liquid level
Below the bottom for being down to protection pipe 2, inside and outside gas keeps connection, and unnecessary gas is discharged to the external world from protection pipe 2, therefore
The air pressure of inside is reduced, positive pressure protection effect is served.
By the setting of protection pipe 2, the pressure inside tank body 1 is maintained positive pressure protection value all the time and be worth it with negative pressure protection
Between, it is to avoid there is pressure too low or too high, it is to avoid the inside and outside differential pressure of fermentation tank is crossed ambassador's malformation and is damaged.The diameter of tank body 1
It is very big, therefore to avoid discharging excessive zymotic fluid, protection pipe 2 is only stretched into distance very short below liquid level.
Specifically, protection pipe 2 is the straight tube being vertically arranged, as long as can connect inside and outside, may be alternatively provided as bend pipe.Protect
The uniform diameter of pillar 2 is consistent, is fixed on the top of tank body 1, if protection pipe 2 is fixedly connected on the side of tank body 1 to be obliquely installed
It is also possible on wall, it can also play identical technique effect.
Specifically, protection pipe 2 is steel pipe, and structural strength is higher, and correspondingly tank body 1 is also cylinder of steel, protection pipe 2 and tank body 1
By being welded and fixed.
Due to fermented liquid and unclean, outside is polluted to prevent that it from outwards spraying, can also be at the end of protection pipe 2
Portion, which is set, can connect the connector of drainpipe, and the top of protection pipe 2 is connected into drainpipe, and be switched in cache pool, to row
The liquid gone out carries out drainage.
The top of tank body 1 is sphere, and protection pipe 2 is arranged at the position that tank body 1 leans on proximal wall, and certainly, specific structure is simultaneously
This is not limited only to, protection pipe 2 is disposed in other locations also possible.
In addition, a liquid after positive pressure protection is entered inside tank body 1 is reduced, therefore in order to be supplemented in time, also set
Water replanishing device is equipped with, water replanishing device is connected on water replanishing device by the connector of the end of protection pipe 2, by protection pipe 2 to tank
The moisturizing of body 1.Water replanishing device can provide enough hydraulic pressure, and water is sent at the protection pipe 2 of eminence.
Protection pipe 2 by protection tank body 1 with being become one, and structure is extremely succinct, stable and reliable operation, it is not necessary to safeguard,
Substantially reduce construction cost and difficulty.It is integrated in tank interior, and eliminating freezed in winter causes the possibility of failure.And in tank body
Liquid level constant is constant, so positive/negative-pressure protection value is invariable.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice, can in other embodiments be realized in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
