The utility model content
The utility model, for the deficiencies in the prior art, provides a kind of electric gas heater, and that this electric gas heater has is energy-saving and cost-reducing, the thermal efficiency is high, long service life, safe, high temperature resistant, high voltage bearing advantage.
For realizing above technical purpose, the utility model will be taked following technical scheme:
A kind of electric gas heater, comprise shell of tank and be arranged on the heat-generating pipe boundling in shell of tank by adpting flange, described shell of tank is respectively arranged with medium inlet, media outlet, it is characterized in that: described shell of tank is double-layer shell structure, described medium inlet is communicated with the interlayer of double-layer shell structure, the interlayer of described double-layer shell structure is communicated with the internal layer container housing of double-layer shell structure by adpting flange, media outlet is communicated with the internal layer container housing of double-layer shell structure, and the heat-generating pipe boundling is placed in the inner chamber of internal layer container housing.
The interlayer of described double-layer shell structure supports by the gripper shoe that circumferentially arranges.
The inner chamber of described internal layer container housing is equipped with at least one be used to supporting the fixed head of heat-generating pipe boundling, between each heat-generating pipe of each piece fixed head and heat-generating pipe boundling, all by refractory ceramics spare, is connected.
According to above technical scheme, with respect to prior art, the utlity model has following beneficial effect:
Container casing of the present utility model adopts double-layer shell structure, medium first passes through the interlayer of this double-layer shell structure, the inner chamber that enters again the internal layer container shell carries out heat treated, hence one can see that: due to the change of gas flow process, the efficiency of heating surface improves, the shell of tank temperature is low, shell is without extra insulation, heat waste little energy-conservation, temperature rate is high, the change of structure of container saves material, and volume is little, power is large, gas flow is large, flow resistance is little, safety anti-explosive, long service life, the advantage such as reliable.

The specific embodiment
Below with reference to accompanying drawing, explain the technical solution of the utility model.
As shown in Figure 1 and Figure 2, gas heater described in the utility model, comprise shell of tank, the two ends of this shell of tank are uncovered setting, wherein an end is connected with terminal box by adpting flange, the power supply that is connected with headstock of terminal box configuration power interface, power interface 2, the other end is installed end socket, and described end socket is provided with media outlet; The medium inlet that also arranges of the present utility model; Heat-generating pipe is supported in container casing by adpting flange, and heat-generating pipe is connected with the terminal box circuit; In container casing, compartment of terrain is equipped with fixed head, and described fixed head offers the through hole of walking for this heat-generating pipe corresponding to heat-generating pipe, and this fixed head, for preventing from being out of shape under heat-generating pipe high temperature, adopts the steel manufacture; In the utility model, described shell of tank is double-layer shell structure, comprises outer layer container shell and internal layer container shell, between outer layer container shell and internal layer container shell, by the gripper shoe that circumferentially arranges, supports, and prevents high temperature deformation; Between heat-generating pipe and fixed head, by ceramic insulator, fix; Medium inlet is communicated with the chuck between two-layer shell of tank, and media outlet is communicated with the inner chamber of internal layer container shell; Chuck between two-layer shell of tank is communicated with the inner chamber of internal layer container shell by vessel flange.
In sum: outer layer container shell pressurized described in the utility model as can be known is not subjected to temperature, internal layer container shell to be subjected to not pressurized of temperature.Gas at normal temperature enters between the chuck of the inside and outside layer of container shell of tank, and the inner chamber that the first preheating cold air of the temperature of internal layer container shell enters the internal layer container shell more further is heated to technological temperature.Heat-generating pipe is made by resistant to elevated temperatures nickel-base alloy seamless steel pipe; Between each heat-generating pipe, by the steel construction fixed head, fixed, fixed head fixedly heat-generating pipe is to prevent from being out of shape under heat-generating pipe high temperature; Between heat-generating pipe and fixed head, with ceramic insulator, fix.The quantity of heat-generating pipe is determined by the resistance value of watt level and steel pipe.
In the utility model, shell of tank changes two layers into by individual layer, because outer layer container shell pressurized is not subjected to temperature, case material can be used the common stainless steel material, only need bear pressure design, the internal layer skin is subjected to not pressurized of temperature, on material, applies exotic material but does not need to bear pressure.Save material.
Adopt the high-temperature gas electric heater of this structure, change due to the gas flow process, the efficiency of heating surface improves, the shell of tank temperature is low, shell is without extra insulation, heat waste little energy-conservation, temperature rate is high, the change of structure of container saves material, and volume is little, power is large, gas flow is large, flow resistance is little, safety anti-explosive, long service life, the advantage such as reliable.
During use, normal temperature air enters between the chuck of outer layer container shell and internal layer container shell from outer end socket 12 ends of equipment by medium import 10, shell cover place does not communicate due to inside and outside layer, the gas that enters container turns back to the inner chamber that vessel flange 3 enters the internal layer container shell, gas is taken away internal layer wall temperature preheated air, reduces the heat conduction of outside wall temperature.Finally by after heat-generating pipe 7 heating, from media outlet 13, discharging.Through the computing the resistor value of general power and heat-generating pipe and confirm the heat-generating pipe of some.Heat-generating pipe is made insulator for its insulating properties of assurance with refractory ceramics spare 6 when passing fixed head 8; Between heat-generating pipe and heat-generating pipe, by steel construction fixed head plate, fixed, steel construction fixed head fixedly heat-generating pipe is to prevent from being out of shape under heat-generating pipe high temperature; Circumferentially between two layers of shell of tank with gripper shoe 9, support and prevent high temperature deformation.Power interface 2 power supply that is connected with headstock.
