Description
Technical field
The invention belongs to urban construction technical fields, and in particular to a kind of anti-blow-up system of sewer.
Background technique
With the development of the city, urban pipe network is laid with more and more intensive, and wherein sewer is most basic in numerous pipelines
A kind of communal facility, main function are for discharging municipal sewage and rainwater.
In recent years, sewer explosion accident all occurred for domestic multiple cities.Explosion Producing reason on the one hand be due to
In pipeline methane content (in sewer there are due to excessive sewage, excrement, under these organic matter anaerobic conditions
Biogas will be generated by undergoing microbial fermentation, will shape when containing the biogas of 8.6%~20.8% (by volume) in air
At volatile mixed gas)；It on the other hand is the carelessness due to people, such as: the cigarette butt not extinguished of smoking has thrown into pipeline
In, fireworks and firecrackers when celebrating a festival accidentally falls into hoistway, and especially some children fond of play are when putting fireworks and firecrackers
Curiosity is easy to throw away fire source into well head, leads to peril.
It is designed with the lid mouth of flowing water greatly additionally, due to the well lid of sewer, it is excessive by existing in prolonged use pipeline
Rubbish (discarded paper scrap, polybag, cigarette butt), not only pollute sewer, but also a large amount of rubbish will affect the circulation of water channel, clearly
Reason trouble.
Summary of the invention
In order to overcome the drawbacks described above of the prior art, the present invention is intended to provide a kind of can prevent when fire source falls into well head

Specific embodiment
Embodiment 1
As shown in Figure 1, the invention discloses a kind of anti-blow-up system of sewer, including be located at 3 lower section of well lid every
From device 1 and pre-buried water pipe 2；The isolating device 1 includes bottom plate 11 and side plate 12, and 11 area covering of bottom plate lives well lid
3, side and hoistway 4 are side walls hinged, and periphery is fixed at the top of the magnetic suction disc and hoistway 4 by being located at 12 top of side plate, bottom plate 11,
Side plate 12 has been integrally formed the accommodating case for entering object (solid and liquid) from well lid 3 in conjunction with the borehole wall, passes through setting for magnetic suction disc
Setting can be such that isolating device 1 is easy to open along hinge side, unlikely influence ordinary maintenance and protection；The set-up mode of side plate 12 can root
It is replaced according to the width of hoistway 4, it can be made integrally to be fixedly connected with bottom plate 11 when hoistway is sufficiently wide, when short of width, can incited somebody to action
Side plate 12 and the rotation connection of bottom plate 11 (such as: hinged) allow it to be folded inward and bottom plate are facilitated to open downwards；The pre-buried water
Pipe 2 penetrates the borehole wall between bottom plate 11 and well lid 3 and extends to 4 bottom of hoistway.
The main component of biogas is methane, and content is that sewer generates the main of explosion in 50%~80%, easy firing
Reason.The present invention is provided with isolating device 1 at well lid 3, and passes through pre-buried water pipe 2 for 1 space of isolating device and 4 bottom of hoistway
Connection, isolating device 1, pre-buried water pipe 2 constitute the channel that rainwater enters hoistway 4, pass through the water flow entered by well lid 3 pre-buried
Water pipe 2 enters 4 bottom of hoistway, and (2 entrance of pre-buried water pipe should be bonded 11 surface of bottom plate as far as possible, between preferably 1mm~3mm；In order to make
Water flow all flows into hoistway 4 as far as possible, and bottom plate 11 should set certain angle by shaft and horizontal plane of hinge joint, and angle is too big
Solids can be made to be deposited in 2 entrance of pre-buried water pipe to block, ordinary circumstance lower angle at 3 °~15 °, preferably 7 °~
11 °), and solid waste then rests in isolating device 1.Since methane compares the light weight of air, in 4 generation of hoistway
After can be to circulating at the top of hoistway 4, and reserved outlet of the water pipe 2 in hoistway 4 reserves water pipe 2 and isolating device 1 is opposite in bottom
Isolation is presented in methane in hoistway 4, therefore the methane content in reserved water pipe is almost nil, when there is fire source to pass through well lid 3
Into after hoistway 4, bottom plate 11 can only be rested on and extinguished up to complete.
As the above analysis, the leakproofness of isolating device 1 plays an important role, and isolation can be made to fill by magnetic suction disc
It sets 1 and closely connect that (connection effect of magnetic suction disc is significant, easy for installation, is needing to 4 internal overhaul of hoistway with the top of hoistway 4
When magnetic suction disc need to only be opened, so that isolating device 1 is hung over hoistway inner wall by hinged end), in the side plate 12 and well
4 top contact periphery of road is equipped with sealing ring to further increase the leakproofness between isolating device 1 and hoistway 4, to prevent hoistway 4
In biogas enter isolating device 1；It is otherwise isolated from the plate that device 1 should be good using fire protecting performance, it is preferred to use silico-calcium gypsum is fine
Plate is tieed up, the board lightweight, non-ignitable, fire resistance is good, and can play acceleration to the fire source fallen on plate containing the crystallization water and extinguish
Effect；Pre-buried water pipe 2 is arranged in 4 side wall of hoistway, it is therefore desirable to which it has good wear-resisting, corrosion resistance, and of the invention is pre-
Burying the use of water pipe 2 glass-ceramic tubre, (cast stone is the ideal replacement material such as steel, iron, lead, rubber, timber, has common metal institute
The highly abrasion-resistant that is not achieved, acid-alkali-corrosive-resisting performance and there is the period for extending equipment and using, reduce maintenance man-hours, improve
Production efficiency reduces the advantages that product cost)；It is blocked to prevent solid waste from entering pipeline, in the pre-buried water pipe 2
Metal filter screen is equipped at entrance and exit.To prevent that the methane quantity in hoistway 4 is excessive full of hoistway, can be pushed up in hoistway 4
Ventilation device is arranged in portion, and biogas is discharged according to the biogas detection limit of hoistway 4.
Compared with prior art, the present invention overall construction design is simple, fire source can be effectively prevent to connect with the biogas in hoistway 4
Touching, avoids the generation of explosion accident；In addition the metal filter screen at 2 entrance and exit of pre-buried water pipe can effectively intercept it is external and
The solid waste of hoistway 4 enters water pipe, and isolating device 1 is also convenient for the waste that recycling falls into well head, prevents pollution hoistway, tool
There is good environment protecting.
Embodiment 2
As shown in Figure 2: the present embodiment is additionally provided with straight pipe 5 and on the basis of embodiment 1 in pre-buried water pipe 2
Biogas detector 6, the straight pipe 5 connect pre-buried water pipe 2 to earth's surface, and 5 nozzle of straight pipe passes through the pipe lid 7 of elastic connection
Gai He, exit are equipped with draught fan 8, and the biogas detector 6, draught fan 8 are electrically connected by control centre.So set
The a small amount of biogas penetrated into long-term use process by 2 tube bottom of pre-buried water pipe can be discharged by setting.Specifically examined by biogas detector 6
The methane content in pre-buried pipeline 2 is surveyed, when reaching alarming value, the draught fan 8 in straight pipe 5 is opened by control centre,
Draught fan 8 blows the pipe lid 7 of elastic connection open after opening, discharge the biogas in pipeline by the nozzle of straight pipe 5, work as biogas
Content closes draught fan 8 when being lower than setting value, and pipe lid 7 drops back into nozzle by elastomeric element.
The present embodiment is more perfect on the basis of embodiment 1, whole system safety can be made higher and can for a long time
It uses, reduces frequency of maintenance, use manpower and material resources sparingly.
Above-described embodiment is only the preferred embodiment of the present invention, any and present invention essence made on the basis of the present invention
It is refreshing with essence consistent modify or improve all should be within protection scope of the present invention.
