Abstract
The utility model relates to a flow equalizing device of an electric gas heater. According to the utility model, an inlet cone and an outlet cone are arranged at two ends of a barrel body of the heater, a gas inlet and a gas outlet are respectively arranged on the inlet cone and the outlet cone, an electric heating pipe bundle is arranged in the barrel body of the heater, and a tapered flow equalizing device is fixed in the inlet cone, and is provided with flow equalizing holes. In the utility model, as the tapered porous flow equalizing device is arranged in the inlet cone of the heater, gas can enter the electric heater after the flow field is uniformly distributed, and heat of the heater and the heated gas is exchanged efficiently, so that energy consumption of the heater can be reduced, and the service life of the heater is prolonged.
Description
Technical field
The utility model relates to electric gas heater, specifically a kind of electric gas heater current equalizer.
Background technology
Mostly existing gas heater is that gas directly gets into electric heater; Because the diameter of gas access is much littler than the diameter at heater heating position, after gas got into electric heater, there was turbulent flow in air-flow; Gas and the heating element heater heat exchange of heating tube bundle outer ring are less; The temperature drift of general outer heating tube causes reduce the service life of heating element heater, and heater heat energy utilization rate is not high.
Summary of the invention
The utility model provides a kind of electric gas heater current equalizer to the problems referred to above, gets into electric heater again after this device makes gas by uniform flow field, and is capable of reducing energy consumption, improves the service life of heater.
Technical scheme according to the utility model: a kind of electric gas heater current equalizer; Be provided with inlet cone and outlet cone at the two ends of heater cylindrical shell; Have gas access and gas vent on said inlet cone and the said outlet cone; The electrical heating tube bank is installed in the said heater cylindrical shell, is fixed with the taper current equalizer that has equal discharge orifice in the said inlet cone.
The drift angle of said current equalizer is greater than the cone angle of said inlet cone.
The parallel axes of said equal discharge orifice is in the axis of said inlet cone.
Said equal discharge orifice is distributed on the said current equalizer.
The external electric heater terminal box that is equipped with of said cartridge heater.
The technique effect of the utility model is: the utility model is provided with taper porous current equalizer in the inlet cone of heater; Get into electric heater after making gas by uniform flow field again; Heater be heated the gas high efficient heat exchanging; Can reduce the energy consumption of heater, and improve the whole service life of heater simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Be further described below in conjunction with the specific embodiment of accompanying drawing the utility model.
Among Fig. 1, comprise gas access 1, inlet cone 2, current equalizer 3, heater cylindrical shell 4, electrical heating tube bank 5, outlet cone 6, gas vent 7, electric heater terminal box 8, equal discharge orifice 9 etc.
As shown in Figure 1; The utility model is a kind of electric gas heater current equalizer; Be provided with inlet cone 2 and outlet cone 6 at the two ends of heater cylindrical shell 4; Have gas access 1 and gas vent 7 on inlet cone 2 and the outlet cone 6, electrical heating tube bank 5 is installed in the heater cylindrical shell 4, the heater cylindrical shell 4 outer electric heater terminal boxes 8 that are equipped with.
The utility model is fixed with the taper current equalizer 3 that has equal discharge orifice 9 in inlet cone 2, the drift angle of current equalizer 3 is greater than the cone angle of inlet cone 2, and all the parallel axes of discharge orifice 9 is in the axis of inlet cone 2, and all discharge orifice 9 is distributed on the current equalizer 3.
The operation principle of the utility model is following: the utility model is provided with taper porous current equalizer 3 in the inlet cone 2 of heater; Get into electric heater again after making the gas that gets into from gas access 1 by uniform flow field; The cross section flow that gas is restrained in 5 spaces in the inflow electrical heating is evenly distributed; The heating tube heat generating part potential energy that departs from the center obtains good heat exchange effect; Heater be heated the gas high efficient heat exchanging, can reduce the energy consumption of heater, and improve the whole service life of heater simultaneously.
