Abstract
The utility model belongs to the technical field of gas purification devices, in particular to a filter used to separate impurities such as tar in biomass gases. The utility model adopts the technical scheme that: the filter comprises filter sticks, a cylinder body, an air inlet positioned at the lower part of the cylinder body, an air outlet positioned at the upper part of the cylinder body, and a drain outlet, wherein, at least one filter stick is arranged in the cylinder body and is parallel to the vertical axis of the cylinder body, a filter stick cover plate is disposed at the lower part of the air inlet in the cylinder body and is in sealed connection with the cylinder wall, upper parts of the filter sticks are in sealed connection with the filter stick cover plate, and filter stick connecting heads at top parts of the filter sticks are positioned at the upper part of the filter stick cover plate. The device keeps the tar content in fuel gas less than or equal to below 6mg per cubic meter, so as to reach the national fuel gas supply standards, prevent blockage caused by too high content of tar and dust on meters and kitchen ranges mounted for gas transmission and distribution and in houses, reduce the repair and maintenance work of kitchen ranges and user meters, extend the service life of follow-up gas transmission and distribution systems and pipelines, and reduce the maintenance of the gas transmission and distribution systems, and the utility model has advantages of good safety and reliability and good application effects, and is suitable for being promoted and applied in rural districts.
Description
Technical field
The utility model belongs to the gas purifying equipment technical field, particularly a kind of filter that is used for impurity such as separating biomass gas tar.
Background technology
Biomass resource is a kind of reproducible clean energy resource, is only second to coal, oil and natural gas, occupies four of the total flow controls of world energy consumption, and the rational exploitation and utilization biomass energy has become the focus of whole world common concern.China's biomass resource is very abundant, at present, has domesticly set up living beings gasification centralizedly supply station, more than 1000 rural area, and plans that area with good conditionsi builds the biomass fermentation power station, promotes household small-size biomass gasifying furnace technology.But, in the biomass pyrogenation gasification technical process, outstanding there are decoking cost height, complex process, cause secondary pollution problems easily, the difficult discharging of the tar that causes biomass gasifying furnace in gasification, to produce, because tar content is big in the combustion gas, cause stopping up to follow-up distributing system, user with the line clogging in the gas system and the flow gas meter, flow meter before the kitchen range, kitchen range bore, the fuel gas of gasifying furnace utilization rate of heat value is low, even can't use this situation, restricted biomass energy technology and promoted the use of on a large scale in the whole nation.
Summary of the invention
The purpose of this utility model is, in order to overcome the deficiencies in the prior art, and provides a kind of filter, and coke tar particles in the combustion gas and ingress filter are gone out, and decoking is effective, cost is low, technology is simple, is fit to apply.
For solving the problems of the technologies described above, the technical solution of the utility model is: filter, comprise filter stick, cylindrical shell, be positioned at the air inlet of cylindrical shell bottom, the gas outlet that is positioned at cylindrical shell top, sewage draining exit, at least one filter stick and the parallel placement of the longitudinal axis of cylindrical shell are arranged in the cylindrical shell, the bottom of air inlet has that filter stick cover plate and barrel are airtight to be connected in cylindrical shell, the top of filter stick is connected with the filter stick cover plate is airtight, and the filter stick connector at filter stick top is positioned at the top of filter stick cover plate.Combustion gas is entered in the filter cylinder by the air inlet of cylindrical shell bottom, filter stick is to sell on the market, the micropore gap is below 6um, when combustion gas is passed through filter stick under certain pressure, keeping off in the filter cylinder greater than tar more than the 6um and dust granule in the combustion gas, by blow-off pipe tar and dust are discharged, combustion gas after the filtration by the filter stick connector from the gas outlet discharge filter, tar content in the combustion gas is limited in below the 6um, thereby reached the purpose of separating gas tar oil, alleviate the ability to work of subsequent technique, significantly reduced the time of maintenance, improved operating efficiency.
Filter stick cover plate described in the utility model is connected with the airtight sealing flange that is connected to of barrel.
The top of filter stick described in the utility model is connected with the airtight sealing flange that is connected to of filter stick cover plate.
Filter described in the utility model also has Pressure gauge to be connected with the cylindrical shell of filter stick cover plate bottom.The Pressure gauge that is connected with filter can be indicated the operating pressure in the filter, can clean or change filter stick when pressure surpasses the certain limit value, has guaranteed the work safety of filter.
Be connected with upper end cover on the cylindrical shell described in the utility model.Can take out filter stick by upper end cover cleans or changes.
The beneficial effects of the utility model are: because filter, comprise filter stick, cylindrical shell, be positioned at the air inlet of cylindrical shell bottom, the gas outlet that is positioned at cylindrical shell top, sewage draining exit, at least one filter stick and the parallel placement of the longitudinal axis of cylindrical shell are arranged in the cylindrical shell, the bottom of air inlet has that filter stick cover plate and barrel are airtight to be connected in cylindrical shell, the top of filter stick is connected with the filter stick cover plate is airtight, and the filter stick connector at filter stick top is positioned at the top of filter stick cover plate.Coke tar particles and moisture content during this device can will atomize under low-pressure state are separated from combustion gas, tar content in the combustion gas is less than or equal to below 6 milligrams for every cubic metre, reach the transfer criteria of state's home fuel gas, prevented that transmission ﹠ distribution and the table tool of registering one's residence and kitchen range are because of tar and the too high obstruction because of rising of dust content, reduced the maintenance load of kitchen range and subscriber's meter tool, increase the service life of follow-up distributing system and pipeline, alleviated the maintenance of distributing system, safe and reliable, effect is good, is adapted at the rural area and applies.
