Description
Technical field
This utility model belongs to gas conveyer tube technical field, particularly to a kind of gas conveyer tube filter protector.
Background technology
Along with gas electricity utilizes reaching its maturity of technology, the gas-to electricity of low concentration gas there has also been incremental advances, and domestic have multiple gas electricity station all to build low-concentration gas power generation system, and single-machine capacity is from 500KW to 1500KW.But, found by operation in the past few years, compared with high concentration gas generating, it is low that low-concentration gas power generation generally also exists generating efficiency, frequent shutdown, and equipment maintenance cost crosses the problems such as height.By finding the relative analysis of multiple low-concentration gas electric station, all there are substantial amounts of aqueous water in the internal or even whole gas piping of low-concentration gas power generation unit, the deposition of these aqueous waters is the principal element causing the problems referred to above occur.
It is closer to owing to methane gas has the blast interval 5～15% that the fluctuation of concentration scope of inflammable and explosive characteristic, especially low concentration gas gas marks under condition with it, therefore defeated at pipe and have the strictest security requirement during utilizing.In course of conveying, according to the requirement of specification AQ1078, must use the mode that water mists carries during low concentration gas conveying, the every 20m of transfer line length to arrange one group of spraying point, it is ensured that gas delivery safety.After these water smokes and low concentration gas blending, some is actually taken up by gas, when the relative humidity of gas reach saturated after, remaining water smoke accumulates in valve, instrument, threeway etc. be likely to occur the place of throttle effect, bottom the most whole conveyance conduit along with the change of Bottomhole pressure state and the change of actual internal area will be condensed into aqueous water again.
Current domestic most low-concentration gas power generation system all uses Gravity Separation formula dewatering type, and the centrifugal action that this mode utilizes gas rotating flowing to produce carries out the removing of aqueous water.But, low concentration gas is owing to being limited by delivery safety, and specification strict regulations gas transporting velocity must not be higher than 15m/s, seriously limits the dehydrating effect of separator, the dewatering efficiency making separator only has 50%-60%, still has operative liquid water to enter inside generating set along with air-flow after dehydration.In device in Gas, the vaporous water molecule even aqueous water containing excess not only causes strong influence to the quality of gas, too increases the operation maintenance workload of rear end equipment simultaneously.
Utility model content
In order to effectively filter the coal dust mixed in methane gas recovery process and other impurity particles; reduce water content in generating methane gas; there is provided the methane gas of the high cleanliness being dried for methane gas generating, this utility model provides a kind of gas conveyer tube filter protector especially.
This utility model is achieved by the following technical programs.
A kind of gas conveyer tube filter protector, it includes Rose Box, condenser and conduit, it is characterized in that: conduit is sequentially connected with the first Rose Box, the second Rose Box and condenser along flow of flue gas direction；
Equipped with water bottom described first Rose Box, described first Rose Box is provided with air inlet, and described air inlet is higher than the water surface, and pipeline inserts in water through air inlet；Being provided with two gas outlets in the one side that the described first enterprising QI KOU of Rose Box is relative, one of them gas outlet is higher than the water surface, and another gas outlet is less than the water surface；
First Rose Box gas outlet is the second Rose Box air inlet, equipped with water bottom described second Rose Box, it is perpendicular to flow of flue gas direction in the middle part of described second Rose Box and is provided with baffle plate, described baffle plate top contacts with the second Rose Box end face, and baffle plate bottom is stretched into and contacted in water and not with the second Rose Box bottom surface；Being provided with gas outlet in the one side that the described second enterprising QI KOU of Rose Box is relative, gas outlet is higher than the water surface.
Described condenser internal temperature is-20 ~-30 DEG C, is provided with discharge gate bottom condenser.
The described horizontal partial interior of conduit level is provided with screen plate.
This utility model compared with prior art has the advantages that.
1, this utility model will directly exploit the low-concentration methane gas of acquisition by the water in the first Rose Box, carrying out the coal dust carried in methane gas and other impurity particles filtering for the first time, the coal dust in methane gas and other impurity particle major parts after filtration have been stayed in the first Rose Box.
2, methane gas methane gas after the first Rose Box filters enters the second Rose Box and filters further, and the coal dust mixed in methane gas and other impurity particles are further filtered.
Although 3, methane gas methane gas impurity particle after the second Rose Box filters effectively is filtered, but methane gas carries substantial amounts of water, therefore methane gas is passed through in condenser, the temperature of condenser is-20 ~-30 DEG C, steam is cooled down and then is formed solid ice, and gas remains gaseous state, effectively it is stripped of the water carried in methane gas, the methane gas of the high cleanliness being dried is provided for the generating of further methane gas.
4, the horizontal partial interior of conduit level is provided with screen plate, and methane gas carries out multiple times of filtration, and solid granular impurity is effectively filtered.
