Abstract
The utility model discloses a back-flow preventer suitable for biomass gas, which includes a water sealed body, a cyclone liquid remover and a liquid drainage water seal, wherein the inlet of the cyclone liquid remover is connected with the top end of the water sealed body; a liquid drainage opening of the cyclone liquid remover is connected with the bottom of the water sealed body; the liquid drainage water seal is connected with the lower part of the water sealed body; ring baffles and a cyclone separator are arranged in the water sealed body, and the ring baffles are positioned below the cyclone separator; and one of a pair of ring baffles is arranged on the inner wall of the water sealed body, and the other ring baffle is arranged on the introduction pipe of the water sealed body and is lower than the ring baffle arranged on the inner wall of the water sealed body. The back-flow preventer can basically remove all the water brought by the gas and the water seal through two stages of removing water. The arranged liquid drainage water seal can ensure an unchanged water level under the circumstance of the constantly increasing of the water content in the water sealed body, so that the pressure fall of the complete device is not changed, and the danger of increasing and overload of the output power of the blower due to the increasing of the pressure fall is avoided. Therefore, the back-flow preventer is favorable for the stable operation of the complete biomass gasification system.
Description
Technical field
The utility model relates to a kind of multi-functional anti-backflow composite set, relates in particular to a kind of multi-functional anti-backflow composite set that is applicable to living beings coal gas.
Background technique
In gas transmission and distribution system, often adopt gas storage holder in present domestic living beings gasification air feed, heat supply, the generating system apparatus.Its effect has two, one, stores the variation of combustion gas in order to compensation usefulness gas load, guarantees the smooth running of fuel gas generating system; The 2nd, for gas ductwork provides a constant transmission ﹠ distribution pressure.Gas storage holder in the gas transmission and distribution system generally moves under 2000～4000Pa pressure, because the gas storage holder operation time is full of inflammable gas, in the operation of fuel gas generating system intermittently or during overhaul of the equipments, gas reflux return-air generation systems is very dangerous.Therefore need in its ingress flame trap and cut-off valve or Safety water seal to be set, when the unit that prevents to gasify stopped aerogenesis, the gas reflux in the gas holder returned unit.
Because biological fuel gas contains tar and dust impurity, easily stop up in valve place deposition, common gas unidirectional safety check is difficult to work definitely reliably for a long time, and common flame trap is to reach the back-fire relief purpose by wire gaze and packing owing to its structure, and the impurity in the combustion gas also deposits and stop up flame trap easily.And common isolation liquid packing can reach the purpose of anti-backflow and back-fire relief, but since its in when operation gas need keep away carrying secretly of unavoidable moisture through water, the water level during operation in the water seal constantly descends, and can make water seal ineffective.And the moisture increase can cause combustion gas quality to descend in the combustion gas, corrosion of piping, especially when in power generation system, using, moisture in the combustion gas can cause the ignition difficulties of gas machine, reduce chamber temperature, reduce the efficient of internal-combustion engine, ponding causes equipment failure, reduces problems such as life of equipment and availability.
Summary of the invention
In order to solve the shortcoming that liquid packing that prior art exists easily makes entrapped moisture in the combustion gas, the utility model provides a kind of back-flow preventer that is applicable to biological fuel gas, has to be difficult for the effective advantage of entrapped moisture anti-backflow.
The utility model adopts following technological scheme:
A kind of back-flow preventer that is applicable to biological fuel gas, form by water seal body, whirlwind liquid knockout and discharge opeing water seal, the import of whirlwind liquid knockout is connected with the top of water seal body, whirlwind liquid knockout liquid port is connected with the bottom of water seal body, the discharge opeing water seal is connected with water seal body bottom, in the water seal body, be provided with ring baffle and cyclone separator, and ring baffle is positioned at the cyclone separator bottom.Described ring baffle is a pair of, and on the inwall that is located at the water seal body, another is located on the inlet tube of water seal body, and is lower than the ring baffle of being located on the water seal inner body wall.
Compared with prior art, the utlity model has following advantage:
(1) owing to is provided with ring baffle and cyclone separator in the water seal body interior, be provided with whirlwind liquid knockout device in the water seal outlet, most of moisture can be by in the retaining backwater envelope body during by ring baffle for water that combustion gas carries and the water carried secretly by water seal, and the tiny globule and mist then enter by cyclone separator and return in the water seal body after the whirlwind liquid knockout separates once more.
(2) the discharge opeing water seal of She Zhiing can guarantee to keep under moisture is on the increase in the water seal body the situation water level constant, it is constant that thereby the pressure that keeps whole device falls, having avoided pressure to fall increasing that blower fan is exerted oneself increases even overload hazard, helps the stable operation of whole biomass gasification system.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of back-flow preventer that is applicable to biological fuel gas, form by water seal body 4, whirlwind liquid knockout 5 and discharge opeing water seal 1,5 imports of whirlwind liquid knockout are connected with the top of water seal body 4, whirlwind liquid knockout 5 liquid ports are connected with the bottom of water seal body 4, discharge opeing water seal 1 is connected with water seal body 4 bottoms, is provided with ring baffle 2 and cyclone separator 3 in water seal body 4, and ring baffle 2 is positioned at cyclone separator 3 bottoms.Described ring baffle 2 is a pair of, and on the inwall that is located at water seal body 4, another is located on the inlet tube of water seal body 4, and is lower than the ring baffle of being located on water seal body 4 inwalls 2.
During operation, combustion gas is entered in water seal body 4 inner chambers by the inlet tube of water seal body 4, combustion gas enters cyclone separator 3 by a pair of ring baffle 2 then, and the water that combustion gas carries after separating with cyclone separator 3 through ring baffle 2 reaches the most of quilt retaining of the water of carrying secretly by water seal backwater and sealed in the body.Enter in the whirlwind liquid knockout 5 by the combustion gas after cyclone separator 3 separation, the process whirlwind liquid knockout 5 isolated tiny globules and mist are deposited to the bottom of whirlwind liquid knockout 5 and return in the water of water seal body 4, and the combustion gas of doing after the separation enters pipeline by the gas outlet of whirlwind liquid knockout 5.
Bottom at water seal body 4 also is provided with discharge opeing water seal 1, when moisture is on the increase in the water seal body 4, can discharge unnecessary liquid by discharge opeing water seal 1 keeps water level constant, it is constant that thereby the pressure that keeps whole device falls, having avoided pressure to fall increasing that blower fan is exerted oneself increases even overload hazard, helps the stable operation of whole biomass gasification system.
