Abstract
The utility model relates to the technical field of electric heating facilities, in particular to a small volume gas electrical heater. The technical problem to be solved by the utility model is to provide a small volume gas electrical heater with no dead zone, the small volume gas electrical heater comprises a honeycomb duct and electric heating beams, an air inlet and an air outlet are formed in the honeycomb duct, and the electric heating beams are arranged in the honeycomb duct. By adopting the heater provided by the utility model, the change of the channel is uniform, the air flow is smooth, and no dead zone exists; the air flow rates of all the channels are the same, so that the possibility of electric heating beam over-burning is nonexistent; the nitrogen is capable of replacing all the air in the channel, so that safe working is guaranteed; the structure of the electric heating beam is more flexible, the electric heating beam can be designed into a plurality of structures, so as to be practical to a situation which has special requirement to the mounting space; and the design of the channel and the electric heating beam can be changed under the working condition that the volume of gas is small.
Description
Technical field
The utility model relates to electrical heating facility technology field, especially a kind of stingy amount natural gas electric heater.
Background technology
In small-sized, miniature natural gas treatment plant, commonly used the conventional electric heating device is that natural gas advances from air inlet to electric heater, and shunting enters a plurality of passages of mozzle and electrical heating interfascicular through inlet plenum, converges and discharge chamber, and flows out by the gas outlet.But there is following defective in the conventional electric heating device: 1, electric heater needs with nitrogen the air displacement of flow passage component is clean before start, guarantees the gas medium trouble free service.In the structure of existing electric heater, at the inlet plenum end, fixed head and mozzle weld, and except between mozzle and electric heater passage being arranged, gas does not have other passage; At the discharge chamber end, gapped between gripper shoe and the mozzle, this gap is when guaranteeing heating, and mozzle can Free Transform, forms one not runny " extremely gas area " between discharge chamber and equipment barrel and mozzle but cause, can't be clean with nitrogen replacement fully.2, a plurality of passages are under the little situation of air-flow, and shunting is uneven, and the heating power of the electric heating tube of each passage is the same, just may cause individual channels " dry combustion method " damage electric heating tube in this case.
The utility model content
Technical problem to be solved in the utility model provides a kind of stingy amount natural gas electric heater that does not have the dead band.
The technical scheme that its technical problem that solves the utility model adopts is: stingy amount natural gas electric heater, comprise mozzle and electrical heating bundle, and described mozzle is provided with air inlet and gas outlet, and described electrical heating bundle is arranged in the mozzle.
Further be that described electrical heating bundle is arranged between air inlet and the gas outlet.
Further be that described air inlet and gas outlet are arranged on the two ends of mozzle.
Further be that described mozzle is installed on the fixed head.
The beneficial effects of the utility model are: because employing is that pipeline heating and gas flow by single channel, so passage changes evenly, air current flow is unobstructed, does not have the dead band existence; All passages are the same by the flow of gas, so just do not have the possibility of electrical heating bundle burning; Nitrogen can all be replaced the air in the passage, guarantees device security work; The structure of electrical heating bundle is more flexible, can be designed to multiple structure, and the occasion practicality very of specific (special) requirements is arranged for installing space; For the operating mode of the very little tolerance of natural gas, can change the design of passage and electrical heating bundle.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is structural representation of the present utility model.
Shown in the figure: 1-fixed head, 2-electrical heating bundle, 3-mozzle, 4-air inlet, 5-gas outlet.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 2, stingy amount natural gas electric heater of the present utility model comprises mozzle 3 and electrical heating bundle 2, and described mozzle 3 is provided with air inlet 4 and gas outlet 5, and described electrical heating bundle 2 is arranged in the mozzle 3.Because air inlet 4 and gas outlet 5 are set directly on the mozzle 3, thus natural gas flow by whole mozzle 3, and no dead bands in the mozzle 3, nitrogen just can guarantee the trouble free service of equipment with the whole air displacement in the mozzle 3.Electrical heating bundle 2 is arranged in the mozzle 3, is heated when natural gas is through mozzle 3 like this.
Air flow rate skewness in the mozzle 3, and the heating power of electrical heating bundle 2 is the same, causes mozzle 3 dry-fire condition to occur, and therefore, as preferred embodiment, described electrical heating bundle 2 is arranged between air inlet 4 and the gas outlet 5.Air inlet 4 is the same with air flow rate between the gas outlet 5, and then electrical heating bundle 2 is arranged between air inlet 4 and the gas outlet 5 and just the dry combustion method phenomenon can occur.
In order to guarantee that nitrogen can replace air in the mozzle 3 fully, as preferred embodiment, described air inlet 4 and gas outlet 5 are arranged on the two ends of mozzle 3.After adopting this structure, nitrogen replacement mozzle 3 air are just more convenient, and displacement fully, avoided potential safety hazard.
For the ease of fixing of electric heater, therefore, as preferred embodiment, described mozzle 3 is installed on the fixed head 1.Mozzle 3 well is fixed by fixed head 1 like this, and as shown in Figure 2, when a plurality of electrical heating bundle 2 is arranged in the mozzle 3, mozzle 3 just has other shapes, mozzle 3 is stable bad at this moment, just needs fixed head 1 to fix mozzle 3, strengthens the stability of mozzle 3.
Embodiment
As shown in Figure 2, mozzle 3 is facade shapes, and there are 3 electrical heating bundles 2 its inside, and mozzle 3 is one-pipes of a connection, and mozzle 3 front end side wall are provided with air inlet 4, and the rear end end face is provided with gas outlet 5, and fixed head 1 is fixed mozzle 3.
During this electric heater work, natural gas enters into mozzle 3 inside from air inlet 4, is subjected to the heating of electrical heating bundle 2 in mozzle 3 inside, 5 outflows from the gas outlet at last.
