Description
Technical Field
The utility model belongs to the technical field of the combustor, more specifically say and relate to a flame detector safety cover.
Background
The flame detector is an important control monitoring unit in a burner system, and has the main functions of monitoring a flame signal when the burner is in normal combustion operation, timely feeding the signal back to a control system when a fault occurs and flameout occurs, cutting off gas, locking a combustion system and preventing accidents from occurring.
The current detection modes mainly comprise a contact type in which an ionization electrode is inserted into flame and an ultraviolet (infrared) non-contact induction type. For a low-nitrogen burner with flue gas external circulation, the flame area is diffused, the testing area of an ionization electrode is limited, and therefore a non-contact induction type burner is generally adopted. The currently used flame detectors are usually mounted in a manner of being separated from the burner, in a manner of being specular-reflective, and in a manner of being directly inserted into the burner. The split type installation mode requires that the holes are arranged in the hearth or other positions where flames can be observed, so that the construction difficulty is increased, and the integration level of the combustor is reduced. The mirror reflection type and the direct insertion type can not avoid the contact with combustion-supporting air, mainly the mixed gas of air and flue gas, condensed water contained in the flue gas and corrosive substances in combustion tail gas easily cause the failure of a mirror coating and the damage of a sensor, and the reliability and the service life of the flame sensor are reduced.
In order to overcome current flame detector on the outer circulation combustor of cigarette, receive the harm of material such as comdenstion water easily, improve the reliability that flame detected and maintain convenient and practical of maintenance, the utility model provides a flame detector safety cover has effectually solved the inside material such as comdenstion water of combustor to flame detector's corrosion problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can improve the reliability, extension equipment life's flame detector safety cover.
The technical scheme of the utility model is that: a flame detector protective cover, comprising: the flame detector comprises a flame detector plug, a flame detector, a backing plate, a flame reflection tube, a pressing plate, a sealing gasket, a quartz glass tube and a fixing plate, wherein the flame detector plug is connected with one end of the flame detector, the other end of the flame detector is connected with the flame reflection tube through the backing plate, the flame reflection tube is sleeved in the quartz glass tube, the quartz glass tube is fixed with the pressing plate through the fixing plate, the sealing gasket is arranged between the fixing plate and the pressing plate, and the backing plate is further fixed on the pressing plate.
To sum up, the beneficial effects of the utility model reside in that: the utility model discloses a flame detector safety cover can ensure the integrated installation of flame detector and combustor, has simplified combustion apparatus's design, and preparation and installation have improved the reliability, have prolonged the life of equipment.
The present invention will be described in more detail by way of examples.
