技术领域technical field

本发明涉及阀门技术领域,特别是涉及一种生物质处理系统流体分路阀。The invention relates to the technical field of valves, in particular to a fluid branch valve of a biomass treatment system.

背景技术Background technique

随着我国社会经济的快速发展城市化进程的加快以及人民生活水平的迅速提高,城市生产与生活过程中产生的垃圾废物也随之迅速增加,生活垃圾占用土地、污染环境的状况越发明显,城市生活垃圾的大量增加,使垃圾处理越来越困难。此外,农业生产中所获得的大量秸秆、木业生产中所获得的大量枝条和木屑,传统方式之一为采用直接焚烧获得热量实现再利用,由此而来的环境污染等问题逐渐引起社会各界的广泛关注。With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the garbage and waste generated in the process of urban production and life have also increased rapidly, and the situation of domestic garbage occupying land and polluting the environment has become more and more obvious. The massive increase of household garbage makes garbage disposal more and more difficult. In addition, a large amount of straw obtained in agricultural production, and a large amount of branches and sawdust obtained in wood production, one of the traditional methods is to use direct incineration to obtain heat for reuse, and the resulting environmental pollution and other problems have gradually caused social problems widespread attention.

如针对垃圾处理,传统垃圾处理过程中,针对无再利用价值的垃圾,最终一般选择填埋处理或焚烧处理。固体废弃物填埋处理生活垃圾不仅占用土地,同时对地下水资源具有较大威胁;垃圾焚烧处理虽然能够实现一定的能量转化、降低后期处理对空间的要求,但在对垃圾进行焚烧时,不仅具有大量的飞灰、氮氧化物产生,同时也会产生二噁英等对环境具有巨大影响的有毒物质,给烟气净化处理和排放带来负担。For example, for waste disposal, in the traditional waste disposal process, landfill or incineration is generally selected for waste that has no reuse value. Solid waste landfill treatment of domestic waste not only occupies land, but also poses a great threat to groundwater resources; although waste incineration can achieve certain energy conversion and reduce the space requirements for post-processing, when incinerating waste, it not only has A large amount of fly ash and nitrogen oxides are produced, and at the same time, dioxins and other toxic substances that have a huge impact on the environment will be produced, which will bring burdens to flue gas purification treatment and emissions.

针对以上问题,现有技术中出现了区别于焚烧,以气化、热解为手段的垃圾等生物质处理设备,采用这些设备,不仅可使得废弃物中的有机物成分能转化为可燃气体、焦油等不同的可方便利用的能量形式,其经济性更好;同时由于所需要的空气系数较低等,故能量利用率高、二噁英等有害气体排放少、尾气处理投入少。In view of the above problems, biomass treatment equipment such as garbage by means of gasification and pyrolysis, which are different from incineration, have appeared in the prior art. Using these equipment, not only can the organic components in the waste be converted into combustible gases, tar Different forms of energy that can be easily used have better economic efficiency; at the same time, due to the low air coefficient required, the energy utilization rate is high, the emission of harmful gases such as dioxins is small, and the investment in tail gas treatment is small.

然而,以上基于气化、热解的生物质处理设备或系统在工作时,如在系统启动初期、系统运行不稳定阶段,所产生的产品气体可能是不达标的甚至是不可利用的,故现有生物质处理系统的出口管线上一般设置有三通阀(或分别在不同管线上均安装一个阀门),以上三通阀中,其中一个阀口作为进气口,另外两个阀口作为出气口,通过相应阀芯,调整进气口与具体出气口的连通状态,以实现根据产品气体的品质,利用不同的阀口输出的形式,实现流体分路输送。However, when the above biomass treatment equipment or systems based on gasification and pyrolysis are working, such as in the initial stage of system start-up or in the unstable stage of system operation, the product gas produced may not meet the standard or even be unusable. A three-way valve is generally installed on the outlet pipeline of the biomass treatment system (or a valve is installed on different pipelines respectively). Among the above three-way valves, one of the valve ports is used as the air inlet, and the other two valve ports are used as the air outlet. , through the corresponding valve core, adjust the connection state between the inlet port and the specific gas outlet port, so as to realize the fluid split delivery according to the quality of the product gas, using different valve port output forms.

现有技术中,相应阀门采用三通阀、截止阀、闸阀等均可达到所需目的,但这些现有阀门通常被分类为高温阀门,存在购买成本高的问题。In the prior art, three-way valves, globe valves, gate valves, etc. can be used as corresponding valves to achieve the desired purpose, but these existing valves are usually classified as high-temperature valves, and there is a problem of high purchase cost.

发明内容Contents of the invention

针对上述提出的用于生物质处理系统的流体分路输送的相应阀门,存在阀门购买成本高的技术问题,本发明提供了一种生物质处理系统流体分路阀。本分路阀不仅结构简单、加工制造成本低,可在现有管线上进过改造获得,同时容易驱动以改变导通状态。Aiming at the technical problem of high purchase cost of the corresponding valves for the fluid branch delivery of the biomass treatment system proposed above, the present invention provides a fluid branch valve for the biomass treatment system. The shunt valve not only has simple structure and low processing and manufacturing cost, can be obtained through modification on existing pipelines, but also can be easily driven to change the conduction state.

针对上述问题,本发明提供的一种生物质处理系统流体分路阀通过以下技术要点来解决问题:一种生物质处理系统流体分路阀,包括阀体及安装在阀体内的阀板,所述阀体包括盲管段及两根出口管,所述出口管的入口端均连接在盲管段的侧面上;In view of the above problems, the present invention provides a fluid branch valve for a biomass treatment system to solve the problem through the following technical points: a fluid branch valve for a biomass treatment system, including a valve body and a valve plate installed in the valve body, the The valve body includes a dead-leg section and two outlet pipes, and the inlet ends of the outlet pipes are all connected to the side of the dead-leg section;

所述阀板呈圆筒状,阀板与盲管段同轴,且阀板安装在盲管段内,阀板的外表面与盲管段的内表面相贴;The valve plate is cylindrical, the valve plate is coaxial with the dead-leg section, and the valve plate is installed in the dead-leg section, and the outer surface of the valve plate is attached to the inner surface of the dead-leg section;

还包括用于驱动阀板绕自身轴线旋转的驱动机构,两出口管中,其中一根出口管为管A,另一出口管为管B;It also includes a driving mechanism for driving the valve plate to rotate around its own axis. Among the two outlet pipes, one of the outlet pipes is pipe A, and the other outlet pipe is pipe B;

所述阀板上还设置有两个连通孔,所述连通孔为贯通阀板内、外侧的通孔;The valve plate is also provided with two communication holes, and the communication holes are through holes connecting the inside and outside of the valve plate;

在其中一个连通孔处于导通管A与盲管段的状态时,另一连通孔与管B位置错开,管B与盲管段处于截断状态;在其中一个连通孔处于导通管B与盲管段的状态时,另一连通孔与管A位置错开,管A与盲管段处于截断状态。When one of the communication holes is in the state of the conduction pipe A and the dead-leg section, the other communication hole is staggered from the position of the pipe B, and the pipe B and the dead-leg section are in a cut-off state; one of the communication holes is in the state of the conduction pipe B and the dead-leg section state, the position of the other communication hole and pipe A is staggered, and the pipe A and the dead-leg section are in a cut-off state.

本方案中,所述盲管段的开口端作为本流体阀门的流体流入端,两出口管作为本流体阀门上的不同流体流出管,且具体与盲管段接通的出口管受所述阀板的控制:通过所述驱动机构驱动阀板转动,当阀板上的连通孔处于连通盲管段与某一出口管的位置时,对应出口管可输出流体。这样,采用本方案,即可根据生物质处理系统的具体工作状态,定义所产生气体包括达标的产品气以及不达标的初始气,控制所产生产品气以及初始气的具体管线走向,以实现所生成气体区别输送。In this solution, the open end of the dead-leg section is used as the fluid inflow end of the fluid valve, and the two outlet pipes are used as different fluid outflow pipes on the fluid valve, and the outlet pipe connected to the dead-leg section is controlled by the valve plate. Control: the valve plate is driven to rotate through the drive mechanism, and when the communication hole on the valve plate is in the position of connecting the dead-leg section with a certain outlet pipe, the corresponding outlet pipe can output fluid. In this way, by adopting this scheme, according to the specific working status of the biomass treatment system, the generated gas can be defined, including the product gas that meets the standard and the initial gas that does not meet the standard, and the specific pipeline direction of the generated product gas and initial gas can be controlled to achieve the desired results. Generate gas differential delivery.

本方案中,在具体制备阀体时,采用三根直管段即可轻易获得:其中一根直管段端部焊接作为盲管段封口端的底板,在该直管段侧面上开设两个管孔后,在各对应管孔位置均焊接一根直管作为所述出口管即可;所述的三根直管段亦可利用现有流体管线上的直管段,即本方案具有在现有管线上经过简单改造即可获得的特点;针对作为阀芯的阀板,可采用直管段钻制连通孔后获得。故从成本上讲,本方案采用一个阀门即可达到流体分路输送作用,同时在阀体和阀芯的制造成本上,相较于现有阀门制造成本和制造难度更低。In this scheme, when preparing the valve body, it can be easily obtained by using three straight pipe sections: the end of one of the straight pipe sections is welded as the bottom plate of the sealing end of the blind pipe section, and after two pipe holes are opened on the side of the straight pipe section, each It is enough to weld a straight pipe at the corresponding pipe hole position as the outlet pipe; the three straight pipe sections can also use the straight pipe section on the existing fluid pipeline, that is, this scheme can be simply modified on the existing pipeline. Obtained features: For the valve plate as the valve core, it can be obtained after drilling a connecting hole with a straight pipe section. Therefore, in terms of cost, this solution can use one valve to achieve the function of fluid distribution, and at the same time, the manufacturing cost of the valve body and the valve core is lower than the manufacturing cost and manufacturing difficulty of the existing valve.

本方案中,由于在调节盲管段与具体出口管导通状态时,阀板配合在盲管段内的特定位置,故针对盲管段内壁富集粉尘的情况,阀板与盲管段的配合面为富集粉尘的死角,这样,通过驱动机构驱动阀板转动时,可有效减少粉尘对阀板转动的影响,故本方案还具有驱动阀板转动轻松的特点。In this scheme, since the valve plate is matched at a specific position in the dead leg section when adjusting the conduction state of the dead leg section and the specific outlet pipe, the mating surface of the valve plate and the dead leg section is rich in dust in the dead leg section. In this way, when the valve plate is driven to rotate through the driving mechanism, the influence of dust on the rotation of the valve plate can be effectively reduced, so this scheme also has the feature of driving the valve plate to rotate easily.

更进一步的技术方案为:A further technical solution is:

为方便敷设位于本分路阀出口端的流体管线,设置为:在盲管段的周向方向上,两出口管连接在所述周向方向上的相同位置。作为本领域技术人员,本方案中,两出口管位于盲管段的不同轴线位置。In order to facilitate the laying of the fluid pipeline at the outlet end of the shunt valve, it is arranged that: in the circumferential direction of the dead-leg section, the two outlet pipes are connected at the same position in the circumferential direction. As a person skilled in the art, in this solution, the two outlet pipes are located at different axial positions of the dead-leg section.

为避免在靠近盲管段入口端的出口管与盲管段导通的情况下,阀板靠近盲管段封闭端的一侧堆积粉尘,导致在切换另一出口管与盲管段导通时,所堆积的粉尘封堵阀板,设置为:还包括通过第二转轴安装于阀板内的翻板,所述翻板可绕第二转轴转动;In order to avoid the accumulation of dust on the side of the valve plate close to the closed end of the dead-leg section when the outlet pipe near the inlet end of the dead-leg section is connected to the dead-leg section, the accumulated dust will seal when the other outlet pipe is switched to conduct with the dead-leg section. The valve blocking plate is configured to: further include a flap installed in the valve plate through the second rotating shaft, and the flap can rotate around the second rotating shaft;

还包括设置于翻板与阀板之间的复位弹簧,所述复位弹簧在自由状态下时,翻板处于截断阀板中部流通空间的状态;It also includes a return spring arranged between the flap and the valve plate. When the return spring is in a free state, the flap is in a state of cutting off the circulation space in the middle of the valve plate;

所述翻板处于截断阀板中部流通空间的状态时,阀板与靠近盲管段开口端的连通孔的边缘相接。本方案中,复位弹簧用于实现翻板封堵阀板状态的自动复位,翻板的驱动形式可采用辅助驱动装置驱动,此状态下翻板可视为蝶阀的阀芯;亦可利用盲管段内的气压驱动,利用气压驱动时,利用第二转轴两侧翻板表面所受气压力大小不同即可实现:第二转轴偏心安装在翻板上即可。这样,翻板在自由状态下,翻板封堵阀板,使得粉尘不能向阀板靠近盲管段封闭端的一侧堆积,在翻板后端的出口管需要与盲管段连通时,通过所述驱动装置或气压迫使翻板转动即可。针对所述复位弹簧,可设置为第二转轴与翻板可转动连接,第二转轴与阀板固定连接,此时,复位弹簧可为设置阀板内侧的螺旋弹簧,且螺旋弹簧的两端分别于阀板及翻板固定连接;亦可设置为第二转轴与翻板固定连接,如第二转轴与翻板过盈配合、第二转轴与翻板键连接,第二转轴与阀板可转动连接,此时,为方便安装,复位弹簧可为设置阀板外侧的扭矩弹簧,且扭矩弹簧的两端分别于第二转轴及阀板固定连接,同时,为方便装配,在阀板的外侧上设置外部直径大于内部直径的台阶孔,所述台阶孔的内侧孔段用于与第二转轴间隙配合,台阶孔的外部孔段用于容纳所述扭矩弹簧。When the flap is in the state of cutting off the circulation space in the middle of the valve plate, the valve plate is in contact with the edge of the communication hole near the open end of the dead-leg section. In this solution, the return spring is used to realize the automatic reset of the flap to block the valve plate state. The driving form of the flap can be driven by an auxiliary drive device. In this state, the flap can be regarded as the spool of a butterfly valve; the blind pipe section can also be used The internal air pressure drive can be realized by utilizing the difference in air pressure on the surface of the flap on both sides of the second rotating shaft when using air pressure: the second rotating shaft can be installed eccentrically on the flap. In this way, when the flap is in a free state, the flap blocks the valve plate so that dust cannot accumulate on the side of the valve plate that is close to the closed end of the dead-leg section. Or the air pressure forces the flap to rotate. For the return spring, it can be set to be rotatably connected to the second rotating shaft and the turnover plate, and the second rotating shaft is fixedly connected to the valve plate. At this time, the returning spring can be a coil spring arranged inside the valve plate, and the two ends of the coil spring are respectively It is fixedly connected to the valve plate and the flap; it can also be set as a fixed connection between the second shaft and the flap, such as the interference fit between the second shaft and the flap, the connection between the second shaft and the flip key, and the rotation of the second shaft and the valve plate At this time, for the convenience of installation, the return spring can be a torsion spring on the outside of the valve plate, and the two ends of the torsion spring are fixedly connected to the second rotating shaft and the valve plate respectively. A stepped hole with an outer diameter larger than an inner diameter is provided, the inner hole section of the stepped hole is used for clearance fit with the second rotating shaft, and the outer hole section of the stepped hole is used for accommodating the torsion spring.

作为一种结构简单的驱动机构实现方案,所述驱动机构包括第一转轴及手轮,所述阀板呈盲管状,且阀板的封口端与盲管段的封口端相贴;As a realization scheme of a driving mechanism with a simple structure, the driving mechanism includes a first rotating shaft and a hand wheel, the valve plate is in the shape of a blind pipe, and the sealing end of the valve plate is attached to the sealing end of the dead pipe section;

盲管段封口端的中部还设置有为通孔的安装孔,所述第一转轴的轴线与盲管段的轴线共线,第一转轴可转动安装于所述安装孔中;The middle part of the sealing end of the dead-leg section is also provided with a through-hole installation hole, the axis of the first rotating shaft is collinear with the axis of the dead-leg section, and the first rotating shaft is rotatably installed in the installation hole;

第一转轴的一端与盲管段的封口端固定连接,手轮与第一转轴的另一端固定连接。以上阀板的封口端与盲管段的封口端相贴,旨在通过两个封口端的相互作用,利于阀板与盲管段的配合精度。One end of the first rotating shaft is fixedly connected with the sealing end of the dead-leg section, and the hand wheel is fixedly connected with the other end of the first rotating shaft. The sealing end of the above valve plate is in contact with the sealing end of the dead-leg section, aiming to facilitate the matching accuracy of the valve plate and the dead-leg section through the interaction of the two sealing ends.

为实现盲管段封口端密封,设置为:还包括用于密封盲管段与第一转轴配合位置的密封装置。In order to realize the sealing of the sealing end of the dead leg section, it is configured to further include a sealing device for sealing the matching position between the dead leg section and the first rotating shaft.

作为一种结构简单、制造成本低、易于维护的密封装置实现方案,所述密封装置为包括压板与密封填料的填料密封机构。As a realization solution of a sealing device with simple structure, low manufacturing cost and easy maintenance, the sealing device is a packing sealing mechanism including a pressing plate and sealing packing.

为避免阀板沿着盲管段的轴线滑动,设置为:所述第一转轴上还设置有用于限定盲管段在第一转轴轴线上位置的限位装置。作为本领域技术人员,所述限位装置可采用安装在第一转轴上的限位凸台、轴用弹性挡圈等,亦可采用可承受轴向力的滚动轴承实现:如采用深沟球轴承,深沟球轴承的内、外侧分别与第一转轴、盲管段的封闭端过瘾配合的方式。In order to prevent the valve plate from sliding along the axis of the dead-leg section, it is provided that: the first rotating shaft is also provided with a limiting device for limiting the position of the dead-leg section on the axis of the first rotating shaft. As a person skilled in the art, the limiting device can be realized by using a limiting boss installed on the first rotating shaft, an elastic circlip for the shaft, etc., or a rolling bearing that can bear axial force: such as using a deep groove ball bearing , the inner and outer sides of the deep groove ball bearing respectively cooperate with the first rotating shaft and the closed end of the dead-leg segment.

由于出口管的出口端一般需要设置管线,故出口管与盲管段的具体导通状态在本分路阀位置是不直观的,为避免出现出口管错误导通的情况出现,设置为:所述第一转轴与盲管段之间还设置有用于实现第一转轴相对于盲管段锁定的锁定装置。所述锁定装置可采用设置于第一转轴与盲管段之间的紧固件,如采用抱箍、插销、锁紧螺帽等。Since the outlet end of the outlet pipe generally needs to be provided with a pipeline, the specific conduction state of the outlet pipe and the dead-leg section is not intuitive at the position of the shunt valve. In order to avoid the occurrence of the wrong conduction of the outlet pipe, the setting is: A locking device for locking the first rotating shaft relative to the dead-leg section is also provided between the first rotating shaft and the dead-leg section. The locking device may adopt fasteners arranged between the first rotating shaft and the dead-leg section, such as hoops, latches, locking nuts and the like.

为尽可能避免阀板入口端盲管段内堆积粉尘,设置为:所述阀板远离盲管段封口端的一端为具有坡面的尖端,所述坡面使得阀板的入口端孔壁呈圆锥形,且在圆锥形段落上,直径最大位置位于阀板的入口端端部。本方案中,所述坡面即为将粉尘导入阀板内,以方便排出的导入面。In order to avoid dust accumulation in the dead-leg section at the inlet end of the valve plate as much as possible, it is set as follows: the end of the valve plate away from the sealing end of the dead-leg section is a tip with a slope, and the slope makes the wall of the hole at the inlet end of the valve plate conical, And on the conical section, the position with the largest diameter is located at the inlet end of the valve plate. In this solution, the slope is an introduction surface for introducing dust into the valve plate for easy discharge.

为方便本分路阀在管线上的连接,设置为:所述盲管段的管口位置、两出口管的出口端均安装有连接法兰。In order to facilitate the connection of the shunt valve on the pipeline, it is set as follows: the nozzle position of the dead-leg section and the outlet ends of the two outlet pipes are all equipped with connecting flanges.

本发明具有以下有益效果:The present invention has the following beneficial effects:

本方案中,所述盲管段的开口端作为本流体阀门的流体流入端,两出口管作为本流体阀门上的不同流体流出管,且具体与盲管段接通的出口管受所述阀板的控制:通过所述驱动机构驱动阀板运动,当阀板上的连通孔处于连通盲管段与某一出口管的位置时,对应出口管可输出流体。这样,采用本方案,即可根据生物质处理系统的具体工作状态,定义所产生气体包括达标的产品气以及不达标的初始气,控制所产生产品气以及初始气的具体管线走向,以实现所生成气体区别输送。In this solution, the open end of the dead-leg section is used as the fluid inflow end of the fluid valve, and the two outlet pipes are used as different fluid outflow pipes on the fluid valve, and the outlet pipe connected to the dead-leg section is controlled by the valve plate. Control: the valve plate is driven by the drive mechanism, and when the communication hole on the valve plate is at the position connecting the dead-leg section with a certain outlet pipe, the corresponding outlet pipe can output fluid. In this way, by adopting this scheme, according to the specific working status of the biomass treatment system, the generated gas can be defined, including the product gas that meets the standard and the initial gas that does not meet the standard, and the specific pipeline direction of the generated product gas and initial gas can be controlled to achieve the desired results. Generate gas differential delivery.

本方案中,在具体制备阀体时,采用三根直管段即可轻易获得:其中一根直管段端部焊接作为盲管段封口端的底板,在该直管段侧面上开设两个管孔后,在各对应管孔位置均焊接一根直管作为所述出口管即可;所述的三根直管段亦可利用现有流体管线上的直管段,即本方案具有在现有管线上经过简单改造即可获得的特点;针对作为阀芯的阀板,可采用直管段钻制连通孔后获得。故从成本上讲,本方案采用一个阀门即可达到流体分路输送作用,同时在阀体和阀芯的制造成本上,相较于现有阀门制造成本和制造难度更低。In this scheme, when preparing the valve body, it can be easily obtained by using three straight pipe sections: the end of one of the straight pipe sections is welded as the bottom plate of the sealing end of the blind pipe section, and after two pipe holes are opened on the side of the straight pipe section, each It is enough to weld a straight pipe at the corresponding pipe hole position as the outlet pipe; the three straight pipe sections can also use the straight pipe section on the existing fluid pipeline, that is, this scheme can be simply modified on the existing pipeline. Obtained features: For the valve plate as the valve core, it can be obtained after drilling a connecting hole with a straight pipe section. Therefore, in terms of cost, this solution can use one valve to achieve the function of fluid distribution, and at the same time, the manufacturing cost of the valve body and the valve core is lower than the manufacturing cost and manufacturing difficulty of the existing valve.

本方案中,由于在调节盲管段与具体出口管导通状态时,阀板配合在盲管段内的特定位置,故针对盲管段内壁富集粉尘的情况,阀板与盲管段的配合面为富集粉尘的死角,这样,通过驱动机构驱动阀板转动时,可有效减少粉尘对阀板转动的影响,故本方案还具有驱动阀板转动轻松的特点。In this scheme, since the valve plate is matched at a specific position in the dead leg section when adjusting the conduction state of the dead leg section and the specific outlet pipe, the mating surface of the valve plate and the dead leg section is rich in dust in the dead leg section. In this way, when the valve plate is driven to rotate through the driving mechanism, the influence of dust on the rotation of the valve plate can be effectively reduced, so this scheme also has the feature of driving the valve plate to rotate easily.
