Abstract
The utility model belongs to an ignition fire-detecting device for a power station boiler, more specifically a device with rotational flow. An ignition transformer, an ion amplifier and a power plug are arranged in a hollow cavity on the tail part of the utility model; a jet pipe, a nozzle, ignition head and a detection head are arranged in a hollow cavity on the head part of the utility model; a gas pipe, a gas inlet, an air inlet and a connection conducting wire are arranged in a hollow cavity on the middle part of the utility model; an annular inner circle which is tooth-shaped rotational flow is arranged in the jet pipe.
Description
The utility model belongs to the igniting fire monitor equipment that a kind of station boiler is used, specifically a kind of three grades of igniting of straight pipe type, fire monitor equipment that has eddy flow.
The igniter that station boiler is used has two kinds of high-energy igniter and high-frequency igniters usually, during use, utilize propulsion plant to send igniter and oil gun to burner hearth, accumulate high voltage with capacitor, puncture generation moment high-energy by discharge tube, convert heat energy to by semiconductor spark plug again, light light oil, refire the main fuel coal dust through atomizing.The shortcoming of this device is that energy is little, can only light general light oil, resemble flash-point and can't light up to the heavy oil more than 180 ℃ at all, and this device does not have flame detection system, can't judge the working condition of this device.
The purpose of this utility model is that design a kind ofly can be lighted high-flash heavy oil reliably, and has the igniting of functions of flame detection, fiery checkout gear.
Its main technical schemes is: in the cavity of igniting, fire monitor equipment afterbody ignition transformer (8) is installed, ion amplifier (9) and attaching plug (10), jet pipe (20), nozzle (2) and igniter head (17), (18) and detection head (19), (3) are installed in the cavity of head, and Gas Pipe (4) and fuel gas inlet (6) and air intlet (11) are installed in the cavity at middle part, and annular inner ring is installed in jet pipe (20) is eddy flow (1) of dentation with being connected lead (12); Detection head and igniter head are continuous lead (12) with the lead that is connected between the transformer; On fuel gas inlet (6) and air intlet (11), an adjustment valve is installed respectively; Connecting flange (5) is installed at rear portion at outer tube (13).
The utility model has the advantages that because eddy flow that annular inner ring is a dentation has been installed in jet pipe, improved ignition effectiveness.Make that the higher heavy oil of flash-point also can be lighted.Secondly,, be convenient to accurately control the ratio of burning-point and air on fuel gas inlet and air intlet, therefore, also improved the ignition intensity of device because the adjustment valve has been installed.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is a circuit block diagram.
As shown in Figure 1: wherein (7) are that Connection Block, (14) are bearing support, and (15) are gang socket, and (16) are attachment plug, among Fig. 2: (21) are power circuit, (22) be mu balanced circuit, (23) are ignition system, and (24) are the feedback indication, (25) be the CPU computer system, (26) for promoting output circuit, (27) are the shaping delay circuit, and (28) are low drift amplifier, (29) be the balance input system, (30) are the ion detection head.
During work, under flame interaction, portion gas produces ionization, when in a single day random ion runs into the electrode of band certain voltage, is just flowed to just producing ion by negative along polarity of electrode, it is micro-current, this micro-current postpones through shaping by the low drift amplifier of high-gain, promotes output and waits circuit to remove to control miscellaneous equipment, as ignition system, feedback indication and CPU computer system etc.
During use, this device is inserted in the burner hearth, and it is fastening by flange and boiler with bolt, open switch, make combustion gas arrive nozzle by fuel gas inlet and Gas Pipe, air arrives nozzle by air intlet by the gap between Gas Pipe and porcelain tube, stirs power switch, make igniter head gas that ignites, nozzle jets out flames.
