Description

本発明は、例えば工場等の空気供給源等として一般産業用に多用されている圧縮機設備の改善に関し、より詳しくは、圧縮気体の使用量の急激な増大により圧縮気体の圧力が変化したとしても、短時間のうちに圧縮気体の圧力を安定させることを可能ならしめるようにした圧縮機設備およびその制御方法に関するものである。   The present invention relates to improvements in compressor equipment that is frequently used for general industries, for example, as an air supply source in factories, etc., and more specifically, it is assumed that the pressure of the compressed gas changes due to a sudden increase in the amount of compressed gas used. The present invention also relates to a compressor facility and a control method thereof that make it possible to stabilize the pressure of the compressed gas within a short time.

圧縮機は、例えば工場等の空気源等として一般産業用に用いられる圧縮機設備において広く使用されており、複数の圧縮機を様々な負荷変動に応じて稼働させて圧力一定制御を行うようにしたものがある。このような圧縮機の台数制御システムの従来技術としては、例えば後述するような構成になるものが知られている。以下、この従来技術に係る圧縮機の台数制御システムの概要を、圧縮機の台数制御システムを適用した圧縮機設備の全体構成を示すブロック図の図４を参照しながら説明する。   Compressors are widely used in compressor equipment used for general industries, for example, as an air source in factories, etc., and operate a plurality of compressors according to various load fluctuations to perform constant pressure control. There is what I did. As a prior art of such a compressor number control system, for example, one having a configuration as described later is known. Hereinafter, an outline of the compressor number control system according to the prior art will be described with reference to FIG. 4 of a block diagram showing an overall configuration of compressor equipment to which the compressor number control system is applied.

この従来技術に係る圧縮機設備は、２台のターボ圧縮機６０，７０と２台のスクリュー圧縮機８０，９０とを備えている。また、これら異なる種類の複数台の圧縮機から圧送される気体を貯蔵するレシーバータンク５２と、このレシーバータンク５２から、例えば動力源として工場の生産ラインの機器やユーティリティ機器へ送られる圧送圧力に応じて、複数の圧縮機の台数制御を行う台数制御盤５１とから構成されている。   The compressor equipment according to this prior art includes two turbo compressors 60 and 70 and two screw compressors 80 and 90. In addition, a receiver tank 52 that stores gas pumped from a plurality of different types of compressors, and a pumping pressure sent from the receiver tank 52 to, for example, equipment or utility equipment in a factory production line as a power source. The unit control panel 51 controls the number of compressors.

このような圧縮機設備において、先ず一の種類のターボ圧縮機６０，７０は、吸込んだ大気を圧縮機本体６４，７４により圧送し、圧送圧力を圧力調節計６６，７６により検出し、圧縮機の負荷が減少した場合には吸込絞り弁６３，７３の開度を絞って圧送流量を減少させ、さらに負荷が減少して吸込絞り弁６３，７３の開度がＬＬＲ（ローリミットリレー）６２，７２により設定される下限開度になってもなお負荷に対して圧送流量が多い場合には、吸込絞り弁６３，７３の開度を下限開度で維持しながら、放風弁６５，７５により必要以上の風量を大気へ放風することにより圧縮機のサージングを回避しながら圧送圧力を制御する定風圧制御方式になっている。   In such a compressor facility, first, one type of turbo compressor 60, 70 pumps the sucked air by the compressor main bodies 64, 74, detects the pumping pressure by the pressure regulators 66, 76, and then compresses the compressor. When the load of the intake throttle valve 63, 73 is reduced, the opening of the suction throttle valves 63, 73 is reduced to reduce the pumping flow rate, and the load is further reduced to reduce the opening of the suction throttle valves 63, 73 to the LLR (low limit relay) 62, If the pumping flow rate is still large with respect to the load even when the lower limit opening set by 72 is reached, the air outlet valves 65 and 75 maintain the opening of the suction throttle valves 63 and 73 at the lower limit opening. It is a constant wind pressure control system that controls the pumping pressure while avoiding the surging of the compressor by discharging more air volume than necessary to the atmosphere.

一方、他の種類のスクリュー圧縮機８０，９０は、大気から吸込んだ空気を圧縮機本体８４，９４により圧送し、レシーバータンク５２内の圧力を圧力センサ５３により検出し、設備への負荷が減少してレシーバータンク５２内の圧力が上昇した場合には、吸込絞り弁８３，９３を全閉すると同時に放風弁８５，９５を全開とし、これによって気体を圧送しない状態（アンロード）とし、逆に負荷が増大してレシーバータンク５２内の圧力が低下した場合には、吸込絞り弁８３，９３を全開にすると同時に放風弁８５，９５を全閉とし、これによって全量圧送する状態（オンロードまたはロード）とし、所謂アンロードとオンロードの切換によりレシーバータンク５２内の圧力を一定に制御するタンク圧一定方式となっている。また、このスクリュー圧縮機８０，９０は、その機側盤６１，７１へアンロードとオンロードの切換指令を入力することにより、吸込絞り弁６３，７３を全閉すると同時に放風弁６５，７５を全開する上記アンロード運転と、吸込弁８５，９５を全開し、これによって気体を全量圧送する上記オンロード運転との切換も可能になっている。   On the other hand, the other types of screw compressors 80 and 90 pump the air sucked from the atmosphere by the compressor bodies 84 and 94 and detect the pressure in the receiver tank 52 by the pressure sensor 53, thereby reducing the load on the equipment. When the pressure in the receiver tank 52 rises, the suction throttle valves 83 and 93 are fully closed and at the same time the discharge valves 85 and 95 are fully opened, so that the gas is not pumped (unloaded). When the pressure in the receiver tank 52 decreases due to an increase in load, the suction throttle valves 83 and 93 are fully opened, and at the same time the discharge valves 85 and 95 are fully closed, so that the entire amount is pumped (on-load). Or a load), and a so-called tank pressure constant system in which the pressure in the receiver tank 52 is controlled to be constant by switching between so-called unloading and on-loading. Further, the screw compressors 80, 90 input unload and on-load switching commands to the machine side panels 61, 71 so that the suction throttle valves 63, 73 are fully closed and at the same time, the air discharge valves 65, 75. It is also possible to switch between the unloading operation in which the valve is fully opened and the on-loading operation in which the suction valves 85 and 95 are fully opened and the gas is pumped in full.

上記ターボ圧縮機６０，７０およびスクリュー圧縮機８０，９０から圧送された気体は一旦レシーバータンク５２内に貯蔵され、このレシーバータンク５２の内圧を圧力センサ５３により検出し、この検出圧力が台数制御盤５１に入力される。この台数制御盤５１では、圧力センサ５３により検出されたタンク内圧力に応じ、圧送に要する圧縮機の台数を選定し、各圧縮機の機側盤６１，７１，８１，９１に対しロード・アンロード指令、あるいは起動・停止指令を出力する。なお、これらの機側盤６１，７１，８１，９１は、所謂各圧縮機の制御盤であり、上記台数制御盤５１からの指令により各圧縮機がロード・アンロード切換あるいは起動・停止する。   Gases pumped from the turbo compressors 60 and 70 and the screw compressors 80 and 90 are temporarily stored in the receiver tank 52, and the internal pressure of the receiver tank 52 is detected by the pressure sensor 53, and this detected pressure is detected by the unit control panel. 51 is input. The number control panel 51 selects the number of compressors required for pumping according to the pressure in the tank detected by the pressure sensor 53, and loads / unloads the machine side panels 61, 71, 81, 91 of each compressor. Outputs load command or start / stop command. These machine side panels 61, 71, 81, 91 are so-called control panels of the compressors, and the compressors are switched between load / unload or started / stopped according to a command from the unit control panel 51.

そして、上記台数制御盤５１は、スクリュー圧縮機８０，９０がロード・アンロード切換制御を行っている間は、ターボ圧縮機６０，７０の制御と干渉しないよう、ターボ圧縮機側の圧力調節計６６，７６の設定圧力を上記スクリュー圧縮機のロード・アンロード切換制御圧力よりも高めに設定する。これとは逆に、スクリュー圧縮機の全台がアンロードあるいは停止している場合には、レシーバータンク５２の圧送圧力が上昇しないよう、上記台数制御盤５１は、ターボ圧縮機側の圧力調節計６６，７６の設定圧力を下げるためのターボ圧縮機への制御圧力切換指令を出力することが可能になっている。なお、符号６７，７７，８７，９７は何れも逆止弁である。   The unit control panel 51 is configured so that the pressure regulator on the turbo compressor side does not interfere with the control of the turbo compressors 60 and 70 while the screw compressors 80 and 90 are performing the load / unload switching control. The set pressures 66 and 76 are set higher than the load / unload switching control pressure of the screw compressor. On the contrary, when all of the screw compressors are unloaded or stopped, the unit control panel 51 is arranged so that the pressure control pressure on the turbo compressor side is not increased so that the pumping pressure of the receiver tank 52 does not increase. It is possible to output a control pressure switching command to the turbo compressor for lowering the set pressures 66 and 76. Reference numerals 67, 77, 87, 97 are all check valves.

従って、この圧縮機設備によれば、常に、形式の異なる複数の圧縮機の中から負荷に対応した必要最小限の台数の圧縮機を選択して圧送するため、設備全体の省力化を行うことができると共に、異なる種類のターボ圧縮機とスクリュー圧縮機の間で制御が干渉することなく、種々の負荷変動に対しても、圧縮機設備の出力であるレシーバータンクからの圧縮空気の出力圧力を一定に制御することが可能になる。さらに、レシーバータンクの容量は、スクリュー圧縮機の容量だけを考慮すれば良いので、レシーバータンクの容量を小さくすることができる（例えば、特許文献１参照。）。
特開平７−１１９６４４号公報 Therefore, according to this compressor equipment, since the minimum necessary number of compressors corresponding to the load are always selected from a plurality of compressors of different types and pumped, the entire equipment can be saved in labor. The output pressure of the compressed air from the receiver tank, which is the output of the compressor equipment, can be adjusted to various load fluctuations without interfering with control between different types of turbo compressors and screw compressors. A constant control becomes possible. Furthermore, since the capacity of the receiver tank only needs to consider the capacity of the screw compressor, the capacity of the receiver tank can be reduced (see, for example, Patent Document 1).
JP-A-7-119644

上記特許文献１に記載された従来例に係る圧縮機設備の場合には、上記のとおり、圧縮機設備は圧力センサによる圧力測定値のみに基づく放風制御弁や圧力制御弁の開度制御によって制御されるように構成されている。従って、末端の圧縮空気を使用する機器における圧縮空気の使用量への追従が遅く、圧力変動を避けることができない。特に、急激な圧縮空気の使用量に変動があった場合、定風圧制御のターボ圧縮機の上限制御圧力Ｐ4を超え、全圧縮機が一斉にアンロード運転になって、圧力が急激に低下して容積型圧縮機の下限制御圧力Ｐ1より低くなると、今後は全圧縮機が一斉にロード運転になるということを繰り返す恐れ、即ち圧力ハンチングを起こす恐れがある。 In the case of the compressor equipment according to the conventional example described in Patent Document 1, as described above, the compressor equipment is controlled by opening control of the air discharge control valve or the pressure control valve based only on the pressure measurement value by the pressure sensor.

For example, a burner corresponds to such a combustion apparatus E.

即ち、前記圧縮機設備１は、後述する圧縮機ユニット２を備えている。この圧縮機ユニット２は、フィルタ２ａ、吸気量調整弁２ｂを介して大気から吸込んだ空気を圧縮する、ロード／アンロード制御（インレットガイドベーン、放風制御弁を備えない。）される汎用の圧縮機本体２ｃを備えている。この圧縮機本体２ｃの吐出口に一端が連結された空気供給基ライン（気体供給基ライン）２ｄの先端に、供給基接続フランジ２ｅが設けられている。前記空気供給基ライン２ｄの圧縮機本体２ｃと供給基接続フランジ２ｅとの間から、途中に放風弁２ｇが介装され、先端にサイレンサＳが設けられてなる緊急放風ライン２ｆが分岐している。   That is, the compressor facility 1 includes a compressor unit 2 described later. The compressor unit 2 is a general-purpose load / unload control (without an inlet guide vane and an air discharge control valve) that compresses air sucked from the atmosphere via a filter 2a and an intake air amount adjustment valve 2b. A compressor body 2c is provided. A supply base connection flange 2e is provided at the tip of an air supply base line (gas supply base line) 2d having one end connected to the discharge port of the compressor body 2c. An emergency air discharge line 2f in which an air discharge valve 2g is interposed in the middle of the air supply base line 2d between the compressor main body 2c and the supply base connection flange 2e and a silencer S is provided at the tip branches. ing.

前記放風弁２ｇの開度は、前記空気供給基ライン２ｄを流れる圧縮空気（圧縮気体）の圧力を検出する第１圧力センサＰＧ1から出力される圧力測定値の信号を受信して前記吸気量調整弁２ｂの開度を制御する圧縮機側操作盤ＣＰによって制御されるようになっている。つまり、前記放風弁２ｇは、前記空気供給基ライン２ｄを流れる圧縮空気の圧力が予め設定されたしきい値を超えると、前記圧縮機側操作盤ＣＰ1により開弁操作されるように構成されている。なお、この放風弁２ｇは必須ではないが、何らかの原因によって圧縮機設備１の圧力が異常に高圧になったときに、異常圧によりこの圧縮機設備１に生じる不具合を回避するために設けられてなるものである。 Opening of the blow-off valve 2g, the intake to receive the signal of the pressure measurement value output from the first pressure sensor PG 1 for detecting the pressure of the compressed air (compressed gas) flowing through the air supply base line 2d It is controlled by a compressor side operation panel CP that controls the opening degree of the amount adjusting valve 2b. That is, the blow-off valve 2g is exceeds a threshold pressure has been set in advance of the compressed air flowing through the air supply base line 2d, adapted to be opened operated by the compressor-side operation panel CP 1 Has been. Although this discharge valve 2g is not essential, it is provided in order to avoid problems caused in the compressor equipment 1 due to abnormal pressure when the pressure of the compressor equipment 1 becomes abnormally high for some reason. It will be.

前記供給基接続フランジ２ｅに一端側が接続された、後述する構成になる空気供給ライン（気体供給ライン）３が前記燃焼装置Ｅに連通している。そして、この空気供給ライン３の途中から、放風制御弁４ａが介装され、先端にサイレンサSが設けられてなる放風ライン４が分岐している。前記放風制御弁４ａの開閉は、前記空気供給ライン３を流れる圧縮空気の圧力を検出する第２圧力センサＰＧ2から出力される圧力測定値の信号を受信する圧力コントローラＰＣによって制御されるように構成されている。なお、この圧力コントローラＰＣには燃焼装置Ｅの図示しない制御装置から前記燃焼装置Ｅに燃料が供給されているか否かを示す燃料供給信号が送信されるように構成されている。従って、前記放風制御弁４ａの開閉は、前記第２圧力センサＰＧ2からの圧力測定値の信号と共に、前記燃料供給信号に基づいて制御される。 An air supply line (gas supply line) 3, which is configured as described later, is connected to the combustion device E, with one end connected to the supply base connection flange 2 e. An air discharge control valve 4 a is interposed from the middle of the air supply line 3, and the air discharge line 4 having a silencer S provided at the tip branches off. The opening and closing of the blow-off control valve 4a is to be controlled by a pressure controller PC that receives a signal of the pressure measurement value output from the second pressure sensor PG 2 for detecting the pressure of the compressed air flowing through the air supply line 3 It is configured. The pressure controller PC is configured to transmit a fuel supply signal indicating whether fuel is supplied to the combustion device E from a control device (not shown) of the combustion device E. Therefore, opening and closing of the blow-off control valve 4a, together with the pressure measurement of the signal from the second pressure sensor PG 2, is controlled based on the fuel supply signal.

また、前記空気供給ライン３の放風ライン４の分岐部と前記燃焼装置Ｅの間、具体的には、この空気供給ライン３の燃焼装置Ｅへの接続部の直前に流量制御弁３ａが介装されている。そして、この流量制御弁３ａの開度は、この空気供給ライン３の流量制御弁３ａの上流側に介装されてなる流量計ＦＭから出力される流量測定値の信号を受信する流量コントローラFＣによって制御されるようになっている。   Further, a flow rate control valve 3a is interposed between the branch portion of the air supply line 4 of the air supply line 3 and the combustion device E, specifically, immediately before the connection portion of the air supply line 3 to the combustion device E. It is disguised. The opening degree of the flow rate control valve 3a is determined by a flow rate controller FC which receives a flow rate measurement value signal output from a flow meter FM interposed upstream of the flow rate control valve 3a of the air supply line 3. To be controlled.

上記構成になる圧縮機設備１によれば、ロード／アンロード制御される圧縮機本体２ｃが駆動されて、空気供給基ライン２ｄ、空気供給ライン３を介して燃焼装置Ｅに燃焼用の圧縮空気が供給される。そして、前記燃料供給信号が燃焼装置Ｅに燃料が供給されていることを示すものである場合、即ち、燃焼装置Ｅが圧縮空気の供給を要する場合にあっては、圧力コントローラＰＣがそれを判断し、さらに（この圧力コントローラＰＣが）第２圧力センサＰＧ2からの圧力測定値の信号に基づき、放風制御弁４ａの開度を調整し、燃焼装置Ｅに供給される燃焼用の圧縮空気の圧力をアンロード圧力以下の一定圧力、つまり圧縮機本体２ｃがアンロードしない一定圧力になるように制御する。 According to the compressor facility 1 configured as described above, the compressor body 2c that is controlled to be loaded / unloaded is driven, and the compressed air for combustion is supplied to the combustion device E via the air supply base line 2d and the air supply line 3. Is supplied. When the fuel supply signal indicates that fuel is being supplied to the combustion apparatus E, that is, when the combustion apparatus E requires supply of compressed air, the pressure controller PC determines that. and further (the pressure controller PC is) based on the signal of the pressure measurements from the second pressure sensor PG 2, and adjusts the opening of the blow-off control valve 4a, the compressed air for combustion supplied to the combustion device E Is controlled to be a constant pressure below the unload pressure, that is, a constant pressure at which the compressor body 2c is not unloaded.

そして、空気供給ライン３に介装されてなる流量計ＦＭから出力される流量測定値の信号を受信する流量コントローラFＣによって開度が制御される流量制御弁３ａにより、燃焼装置Ｅに一定量の燃焼用の圧縮空気が供給される。このことは、燃料と空気との混合割合を安定させるから、燃焼装置Ｅが安定運転されることを意味する。一方、燃焼装置Ｅの運転開始等、燃料が燃焼装置Ｅに供給されていないときには、その燃焼装置Ｅに燃焼用の圧縮空気の供給を要しない。その場合、圧力コントローラＰＣは前記燃料供給信号が燃焼装置Ｅに燃料が供給されていないことを示すものであることを判断し、放風制御弁４ａを全開させる。すると、圧縮機本体２ｃから吐出される圧縮空気の全量が放風制御弁４ａの開弁により空気供給ライン３から放風されるので、圧縮機本体２ｃがアンロード運転になることなく、ロード運転が継続される。勿論、燃焼装置Ｅへの燃料の供給開始に併せて放風制御弁４ａは全開の状態から脱し、上記のとおり、第２圧力センサＰＧ2からの圧力測定値の信号に基づき開閉される。 A certain amount of fuel is supplied to the combustion apparatus E by the flow rate control valve 3a whose opening degree is controlled by the flow rate controller FC that receives the flow rate measurement value signal output from the flow meter FM interposed in the air supply line 3. Compressed air for combustion is supplied. This means that since the mixing ratio of fuel and air is stabilized, the combustion device E is stably operated. On the other hand, when the fuel is not supplied to the combustion device E, such as when the operation of the combustion device E is started, the combustion device E does not need to be supplied with compressed air for combustion. In that case, the pressure controller PC determines that the fuel supply signal indicates that no fuel is supplied to the combustion device E, and fully opens the air discharge control valve 4a. Then, since the entire amount of compressed air discharged from the compressor main body 2c is discharged from the air supply line 3 by opening the air discharge control valve 4a, the compressor main body 2c is not unloaded and loaded. Will continue. Of course, the blow-off control valve 4a in accordance with the start of the supply of fuel to the combustion device E emerged from fully open, as described above, is opened and closed based on a signal from the pressure measurements from the second pressure sensor PG 2.

本発明の形態１に係る圧縮機設備１によれば、上記のとおり、燃焼装置Ｅが運転されていて、燃焼装置Ｅが圧縮空気の供給を要しているときには、第２圧力センサＰＧ2により測定される燃焼用の圧縮空気の圧力が、圧縮機本体２ｃのアンロードを回避し得る一定圧力になるように、圧力コントローラＰＣによって放風制御弁４ａの開度が制御されるから、燃焼用の圧縮気体の圧力変動の発生が防止される。また、圧力変動のない安定した位置、つまり空気供給ライン３の流量制御弁３ａの介装位置より上流側位置における圧縮空気の流量を測定する流量計ＦＭの圧力測定値の信号を受信する流量コントローラＦＣによって流量制御弁３ａを制御するため燃焼装置Ｅに安定した量の圧縮空気を供給することができるのに加えて、燃焼装置Ｅに供給する圧縮空気の圧力を短時間のうちに安定させることができる。 According to the compressor facility 1 according to the first embodiment of the present invention, as described above, when the combustion apparatus E is in operation and the combustion apparatus E needs to supply compressed air, the second pressure sensor PG 2 Since the opening degree of the discharge control valve 4a is controlled by the pressure controller PC so that the measured pressure of the compressed air for combustion becomes a constant pressure that can avoid unloading of the compressor body 2c, Occurrence of pressure fluctuations in the compressed gas is prevented. Further, a flow rate controller that receives a signal of a pressure measurement value of a flow meter FM that measures a flow rate of compressed air at a stable position without pressure fluctuation, that is, an upstream position relative to the position where the flow control valve 3a of the air supply line 3 is interposed. In addition to being able to supply a stable amount of compressed air to the combustion device E to control the flow control valve 3a by FC, the pressure of the compressed air supplied to the combustion device E can be stabilized in a short time. Can do.

従って、本発明の形態１に係る圧縮機設備１では、上記特許文献１に記載されてなる従来例に係る圧縮機設備のように、急激な圧縮空気の使用量に変動があっても、圧縮機本体がアンロード運転になったり、ロード運転になったりすることを繰り返すようなことがないから、圧力ハンチングを起こすようなこともない。   Therefore, in the compressor facility 1 according to the first embodiment of the present invention, even if there is a sudden change in the amount of compressed air used, as in the compressor facility according to the conventional example described in Patent Document 1, the compression facility 1 is compressed. There is no possibility of pressure hunting because the main body never repeats unloading or loading.

本発明の形態２に係る圧縮機設備を、この圧縮機設備の全体構成を示すブロック図の図２を参照しながら以下に説明する。但し、本発明の形態２に係る圧縮機設備が上記実施の形態１に係る圧縮機設備の構成と相違するところは、空気供給ラインの途中にレシーバータンクが介装されている点、並びに放風ラインの接続位置が相違する点にあり、これらの点以外は上記実施の形態１に係る圧縮機設備と同構成になるものである。従って、本発明の形態２に係る圧縮機設備の構成については、上記実施の形態１に係る圧縮機設備と同一のもの並びに同一機能を有するものに同一符号を付して、主としてその相違する点について説明する。   The compressor equipment according to Embodiment 2 of the present invention will be described below with reference to FIG. 2 of the block diagram showing the overall configuration of the compressor equipment. However, the difference between the compressor facility according to the second embodiment of the present invention and the configuration of the compressor facility according to the first embodiment is that a receiver tank is interposed in the middle of the air supply line, and the air discharge The connection positions of the lines are different, and the configuration other than these points is the same as that of the compressor equipment according to the first embodiment. Therefore, about the structure of the compressor installation which concerns on Embodiment 2 of this invention, the same code | symbol is attached | subjected to the same thing as the compressor installation which concerns on the said Embodiment 1, and the same function, and the difference mainly Will be described.

本発明の形態２に係る圧縮機設備１では、図２に示すように、空気供給ライン３の途中に、圧縮空気を貯留するレシーバータンク５が介装されている。そして、このレシーバータンク５に、先端にサイレンサＳが設けられると共に、放風制御弁４ａが介装されてなる放風ライン４の基端側が接続されてなる構成になっている。   In the compressor facility 1 according to Embodiment 2 of the present invention, as shown in FIG. 2, a receiver tank 5 that stores compressed air is interposed in the middle of the air supply line 3. The receiver tank 5 is provided with a silencer S at the tip, and is connected to the base end side of the air discharge line 4 in which the air discharge control valve 4a is interposed.

本発明の形態２に係る圧縮機設備１では、上記のとおり、空気供給ライン３にレシーバータンク５が介装されていて、このレシーバータンク５に圧縮空気が貯留されている。従って、本発明の形態２に係る圧縮機設備１によれば、燃焼装置Ｅの圧縮空気の消費量が変動しても、空気供給ライン３とレシーバータンク５内の圧縮空気の圧力変動が抑制され、燃焼装置Ｅに供給する圧縮空気の圧力・流量を上記請求項１に係る圧縮機設備１の場合よりも迅速に安定させることができるという優れた効果を得ることができる。   In the compressor equipment 1 according to the second embodiment of the present invention, the receiver tank 5 is interposed in the air supply line 3 as described above, and compressed air is stored in the receiver tank 5. Therefore, according to the compressor facility 1 according to the second embodiment of the present invention, even if the amount of compressed air consumed by the combustion device E varies, the pressure variation of the compressed air in the air supply line 3 and the receiver tank 5 is suppressed. Further, it is possible to obtain an excellent effect that the pressure and flow rate of the compressed air supplied to the combustion device E can be stabilized more quickly than in the case of the compressor equipment 1 according to the first aspect.

本発明の形態３に係る圧縮機設備を、この圧縮機設備の全体構成を示すブロック図の図３を参照しながら説明する。但し、本実施の形態３に係る圧縮機設備が上記実施の形態２に係る圧縮機設備と相違するところは、上記実施の形態２に係る圧縮機設備と同構成になる圧縮機設備が複数セット併設されている点、並びにレシーバータンク同士が連通可能に構成されている点にあり、これらの点以外は上記実施の形態３に係る圧縮機設備と同構成になるものである。従って、本発明の形態３に係る圧縮機設備の構成については、上記実施の形態２に係る圧縮機設備と同一のもの並びに同一機能を有するものに同一符号を付して、主としてその相違する点について説明する。   The compressor equipment according to Embodiment 3 of the present invention will be described with reference to FIG. 3 of the block diagram showing the overall configuration of the compressor equipment. However, the difference between the compressor facility according to the third embodiment and the compressor facility according to the second embodiment is that a plurality of sets of compressor facilities having the same configuration as the compressor facility according to the second embodiment are provided. This is in the point that the receiver tanks are configured to be communicable with each other, and the configuration other than these points is the same as that of the compressor facility according to the third embodiment. Therefore, about the structure of the compressor installation which concerns on Embodiment 3 of this invention, the same code | symbol is attached | subjected to the thing same as the compressor installation which concerns on the said Embodiment 2, and the same function, and the difference mainly Will be described.

即ち、本発明の形態３に係る圧縮機設備では、上記形態２に係る圧縮機設備と同構成になる圧縮機設備１と燃焼装置Ｅとの組み合せからなる圧縮空気供給システム（圧縮気体供給システム）が複数セット併設されている。これら複数の圧縮気体供給・消費システムそれぞれの隣接するレシーバータンク５同士が、後述する連通ライン６で接続されている。   That is, in the compressor equipment according to Embodiment 3 of the present invention, a compressed air supply system (compressed gas supply system) comprising a combination of the compressor equipment 1 and the combustion device E having the same configuration as the compressor equipment according to Embodiment 2 above. There are multiple sets. Adjacent receiver tanks 5 of each of the plurality of compressed gas supply / consumption systems are connected by a communication line 6 described later.

そして、この連通ライン６のそれぞれに開閉弁６ａが介装されると共に、それぞれの開閉弁６ａを挟む両側に、圧縮空気の圧力が設定圧力以上になったときに前記開閉弁６ａを閉弁させる一方、設定圧力以下になったときに開閉弁６ａを開弁させる圧力スイッチ（開閉弁開閉手段）ＰＳが設けられてなる構成になっている。なお、この形態３の場合には、上記のとおり、圧力スイッチＰＳにより開閉弁６ａが開閉されるように構成されているが、例えば圧力センサで開閉させるように構成しても良い。また、開閉弁６ａは、開度の中間の制御ができない全開、全閉タイプのものでよい。   An open / close valve 6a is interposed in each of the communication lines 6, and the open / close valve 6a is closed on both sides of the open / close valve 6a when the pressure of the compressed air exceeds a set pressure. On the other hand, a pressure switch (open / close valve opening / closing means) PS for opening the open / close valve 6a when the pressure becomes lower than the set pressure is provided. In the case of the third embodiment, as described above, the opening / closing valve 6a is opened / closed by the pressure switch PS. However, the opening / closing valve 6a may be opened / closed by a pressure sensor, for example. The on-off valve 6a may be a fully open or fully closed type that cannot be controlled in the middle of the opening.

従って、本発明の形態３に係る圧縮機設備によれば、個々の圧縮空気供給システムでは上記形態２に係る圧縮機設備の場合と同等の効果を得ることができる。さらに、圧縮空気供給システムの集合体では、１台の圧縮機本体２ｃだけでは、その圧縮空気供給システムの燃焼装置Ｅに供給する圧縮空気が不足するような場合、具体的には燃焼装置の圧縮空気の消費量が圧縮機本体１台の吐出量よりも多い場合であっても、他の圧縮空気供給システムのレシーバータンク５から連通ライン６を介して圧縮空気を補充して圧縮空気を供給することができる。そのため、燃焼装置Ｅに対してより柔軟に対応することができるという効果を得ることができる。   Therefore, according to the compressor equipment according to Embodiment 3 of the present invention, the individual compressed air supply system can obtain the same effects as those of the compressor equipment according to Embodiment 2 described above. Furthermore, in the assembly of compressed air supply systems, when the compressed air supplied to the combustion device E of the compressed air supply system is insufficient with only one compressor body 2c, specifically, the compression of the combustion device is performed. Even when the amount of air consumption is larger than the discharge amount of one compressor body, the compressed air is supplied by replenishing the compressed air from the receiver tank 5 of another compressed air supply system via the communication line 6. be able to. Therefore, the effect that it can respond to the combustion apparatus E more flexibly can be acquired.
