Definitions

  • Bidirectional anti-explosive arrester especially for pipe systems.
  • Patent is concerned with bidirectional anti-explosive arrester especially for pipe systems.
  • This arrester is intended for barring and damping of explosion of high explosive medium to prevent industrial accidents especially oil industry, chemical industry, pharmaceutical industry and also food industry.
  • the fluid and gas substances are used in many industrial branches, which create with air explosive mixtures. It is mainly the petrochemical industry, chemical industry, pharmaceutical industry including food industry. Storage, transport, processing and manipulation with these substances brings explosion risk especially on critical places like ventilation systems of tanks and containers, pipe systems joints and everywhere where is the possibility of contact of these substances with air. Minimization of consequences and the tendency to distract these technical accidents is solved by anti-explosive arresters, which task is to allow free flow of gas and vapours or other media but in case of explosion to prevent flame passing and its transfer from one section to another one.
  • Disadvantage of the anti-explosive arrester using this insert is mainly that there is not guaranteed a full suppression ability of individual insert in extreme requirements on high explosive media, which can not be constructed in such axial length without placing higher amount of arresters in the arrester assembly between flanges. Between single inserts are formed contact points which create unwanted combustion chambers where the unwanted flame re-ignition happens and the final suppression is complicated.
  • a bidirectional anti-explosive arrester removes above mentioned insufficiencies and largely fulfils the reason of the patent, especially for pipeline systems. It consists of the arrester body connected into a pipeline tubing, in which hole is fitted anti-detonating segment insert according to the patent, whose principle consist in that the arrester body is created by the housing closely copying the outside body profile of the anti-detonating segment insert whereas the housing is equipped on one end with inlet chamber of housing and on the other end with outlet chamber of housing and whereas the inlet chamber of housing and outlet chamber of housing are equipped on their outside end with connecting pipeline thread and whereas the inlet chamber of housing, arrester housing and housing outlet chamber create one rigid compact unit.
  • the inlet chamber of housing and outlet chamber of housing are equipped with axially and radially adjustable flanges.
  • the inlet chamber and outlet chamber are equipped with control holes with plugs.
  • the inlet chamber and outlet chamber are also equipped with thermal sensors and/or pressure sensors and/or detector sensors.
  • the arrester body is equipped with hearing elements with regulation sensors of heating elements.
  • the thermal and/or pressure and/or detector sensors, heating elements and regulation sensors of heating elements are connected to the electronic evaluation unit.
  • bidirectional anti-explosive arrester according to the patent are firstly in that the its construction is one integral very rigid unit which requires very small build-in space, what brings in the pipeline system space saving and improvement of manipulation both installation itself and service works.
  • Design of the arrester with axially and radially adjustable flanges allows easier installation in places with limited spaces for instance for exchange of arresters for another type without the need of reduction of connected length.
  • Design of arrester according to the patent allows flow of media through the arrester with minimum limitation and in case of explosion is its failure rate minimal what allows in many cases repeatable installation of the original arrester in the system or its remaining in the place.
  • Type of construction of the arrester allows placing of pressure, thermal and detection sensors in places, where required values and property of media can be read and monitored instantaneous state of flowing media and arrester by their connection to the electronic evaluation unit and eventually set read values according to requirements and operation safety.
  • Ion extreme temperature conditions can be installed into the arrester body a heating element with regulation sensor of heating element which ensures heating and operation efficiency of the arrester for low temperatures especially for flow of media with low solidification point in cases like freezing and frost risk of the arrester body itself.
  • the configuration of control holes enables easy visual control of the situation of anti-detonating segment insert during service works

  • bidirectional anti-detonating insert Function of bidirectional anti-detonating insert according to the patent is that in the normal state the media flows through anti-detonating segment insert and through the arrester body 2 in the direction of media flow s without significant limitation, which is given highly acceptable continuity especially of anti-detonating segment insert 1 and also other parts of arrester. Passed amount of media can be satisfied by in advance selection of passing channels dimension of anti-detonating segment insert i and also by selection of dimension of inlet chamber 2.2 and outlet chamber 23 independently on the direction of its flow direction, where the anti-detonating arrester functions in the same way and only inlet chamber 22 is changed into outlet chamber 23_and conversely. In case of explosion occurs very intensive breakthrough of blast wave and followed by flame.
  • arrester allows direct passing of blast wave and flame without any transverse obstructions only by using of axial length of anti-detonating segment insert I x which is one of basic parameters for its requested function. Because it is possible to install anti-detonating insert I into the arrester body 2 like one monolithic unit with any axial length, are so removed single interruptions and connections, which are otherwise normally for current constructions of anti-detonating insert. This causes existence of air gaps and it is reason of next flame initiation and lower suppression effect of the arrester.
  • heating elements 7, 7.1 and regulating sensors 8.8.1 can be connected electronic evaluation unit and monitor and adjust requested parameters of arrester using computer (PC).
  • Heating elements 7, 7.1 with regulating sensors 8, 8.1 can be used in extreme weather conditions for heating of the arrester body 2 to prevent freeze-up and in these conditions can be warm up passing media with low solidification point to improve passing.
