Abstract
The utility model relates to a thermal insulation material-free thermal insulation device for a gas heater. A steel sleeve is additionally welded on the outer surface of the heating area of an electric heating pipe; the steel sleeve is hollow; the lower part of one side of the steel sleeve is provided with a hydrogen inlet; the upper part of the other side of the steel sleeve is provided with a hydrogen outlet; the middle part of the steel sleeve is provided with a throttle plate; the steel sleeve is provided with a passage for the hydrogen to enter the heating area. In order to overcome the defect that a conventional heater needs thermal insulation material for heat insulation, by using a method that a heated medium cold fluid continuously absorbs heat, conductive heat energy outside the heating area of the hydrogen heater is continuously introduced to the heating area again, the defect of heat loss caused by heat conduction of the thermal insulation material is overcome, and meanwhile, the maintenance cost for replacing the thermal insulation material which is invalid is reduced.
Description
Technical field
The utility model relates to powder metallurgy gas heater heat preservation technology field, particularly, is a kind of gas heater attemperator without insulation material.
Background technology
At present, in tungsten powder, nickel powder, cobalt powder industrial production engineering, conventionally need to adopt hydrogen reduction method, by tungstic acid, nickel oxide, cobalt oxide powder at high temperature with hydrogen generation reduction reaction, generate metal dust and steam.In production process, the 5-10 that the actual amounts of hydrogen that passes into reduction furnace of needs is actual needs reacting dose doubly.If reduction furnace remaining hydrogen out all emptying or igniting burn, can cause the serious waste of the energy.Because the hydrogen that every production is one cubic metre need consume the electric weight of 5.5 kilowatt hours.So must reclaim purifying dehydration from the remaining hydrogen of getting rid of in stove reuses.
Conventionally in hydrogen purification dewatering system, need to use water suction tower.Water suction tower need to be used two, and each water suction tower is equipped with molecular sieve or silica gel, and housing structure is identical, and molecular sieve or silica gel charge weight equate.In production operation process, two water suction towers are used alternatingly, and one is work tower, and for water suction, another is regenerator, for thermal dehydration and cooling.The cooling complete work tower that proceeds to of regenerator thermal dehydration, and after work tower silica gel or molecular sieve full of water, proceed to regeneration, circulation and so forth, can make the continuous operation of hydrogen purification dewatering system.
At present, in regenerator, heating, dehydration, drying medium are the high-temperature hydrogen of 180 ℃ of serviceability temperatures.High-temperature hydrogen need to obtain with hydrogen heater.Traditional hydrogen heater is for reducing heat-energy losses, and for the appearance of the thermal treatment zone, insulation material is incubated, but no matter use what insulation material can not reach all the time adiabatic effect, because there is certain heat transfer coefficient.In actual production, long-time continuous is used, and insulation material appearance exists certain temperature, and this explanation uses thermal insulation material to be incubated still larger heat-energy losses.And use through long-time, aging along with insulation material, heat-energy losses was increasing until insulation material lost efficacy needed to change.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provide a kind of reasonable in design, can overcome conventional heater and need use the existing shortcoming of insulation material, avoid causing heat-energy losses and need to change loaded down with trivial details that insulation material causes.
The technical scheme in the invention for solving the above technical problem is: a kind of gas heater attemperator without insulation material, at electric heating tube thermal treatment zone outer surface, be welded with a steel bushing, in steel bushing, be hollow, at steel bushing one side lower part, be provided with hydrogen inlet, on steel bushing opposite side top, hydrogen outlet is housed, at steel bushing medium position, be also provided with choke block, on steel bushing, be provided with hydrogen and enter thermal treatment zone passage.
The beneficial effect of this utility model is: this utility model need be incubated existing shortcoming with insulation material for conventional heater, adopt the heated medium cold conditions fluid method of heat absorption continuously, the heat energy of conduction outside the hydrogen heater thermal treatment zone is brought into the thermal treatment zone continuously again, solved the shortcoming that produces heat-energy losses due to the conduction of insulation material heat, also saved because insulation material loses efficacy and changed the maintenance cost of insulation material simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram.
In figure, 1, hydrogen outlet; 2, hydrogen enters thermal treatment zone passage; 3, electric heating tube; 4, choke block; 5, steel bushing; 6, the thermal treatment zone; 7, hydrogen inlet.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
The gas heater attemperator without insulation material as shown in Figure 1, at electric heating tube 3 thermal treatment zone 6 outer surfaces, be welded with a steel bushing 5, in steel bushing 5, be hollow, at steel bushing 5 one side lower parts, be provided with hydrogen inlet 7, on steel bushing 5 opposite side tops, hydrogen outlet 1 is housed, at steel bushing medium position, be also provided with choke block 4, on steel bushing 5, be provided with hydrogen and enter thermal treatment zone passage 2.
During this utility model work, cold conditions medium first enters steel bushing 5 from hydrogen inlet 7, and cold conditions medium enters the thermal treatment zone 6 entering thermal treatment zone passage 2 from hydrogen after the 6 appearance heat absorption of the thermal treatment zone, after hydrogen heating, from hydrogen outlet 1, flows out.Choke block 4 for regulate hydrogen stream to, electric heating tube 3 for heating.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
