Abstract
A resistance far-infrared heater is composed of a heated vessel and a heating part, of which the heating part comprises a far-infrared radiation board, a resistance strip and a power source connecting with the resistance strip; the far-infrared radiation board is circled around the vessel, and the gap is remained between the internal surface of the far-infrared radiation board and the circumferential face of the vessel; the resistance strip is stuck to the far-infrared radiation board.
Description
Technical field
The utility model relates to the equipment that pressure vessels for the chemical industry is heated, and specifically, is a kind of resistance far-infrared heater that utilizes electric energy.
Technical background
The method that pressure vessels for the chemical industry (as reactor (pot), oil supply tank, tank body, pipe tower, coil pipe device etc.) is heated has frequency inductance to answer heating, the straight fiery heating of industrial furnace, conduction oil cyclic heating method traditional approachs such as (being commonly called as the oil bath still).Frequency inductance answers the shortcoming of heating to be, Fei Gong, and power consumption is big, power factor Cos Φ 0.65, its alternating magnetic field that gives off injury health.The heat of the straight fiery heating of industrial furnace is imitated extremely low, and administrative expenses are big, smoke pollution environment.The conduction oil cyclic heating method is applicable to heating below 200 ℃, and the thermal losses of oil accounts for 20～30%, administrative expenses height, the easy contaminated environment of the oil gas of seepage.
Summary of the invention
The technical problem that the utility model solves is exactly the problem that existing heat efficiency of heater is low, waste energy, a kind of electrothermal efficiency＞0.96 is provided, and the heating surface temperature is even, not coking of material, maintenance management is easy, the resistance far-infrared heater that cost of equipment is low.
The utility model resistance far-infrared heater comprises heated container, heater block; Described heater block comprises far infrared radiation plate, resistor stripe, the power supply that links to each other with resistor stripe; The far infrared radiation plate is looped around the periphery of container, and is gapped between the inner surface of far infrared radiation plate and the outer peripheral face of container; Resistor stripe pastes mutually with the far infrared radiation plate.
When using the utility model, generate heat after the resistor stripe energized, the resistor stripe after being heated pastes the far infrared radiation plate with heat transferred mutually with it, and the far infrared radiation plate is heated, and the back is radiation infrared to be absorbed by heated container and its inner material.Radiation and absorption at far infrared are transformed under the effect of heat, the interior material of container is heated accelerates to heat up." far infrared " heating is to strengthen the radiant heat transfer technology on the complex heat transfer basis.Because far infrared radiation has the effect of strengthening the material internal motion, the minimizing " conduction " that it can be relative and " convection current " loss, thereby can obtain energy-saving effect.
As improvement, on the inner surface of far infrared radiation plate, be coated with coatings capable of preventing from far infrared radiation.Have the effect of strengthening far infrared radiation plate radiations heat energy like this.
As improvement, on the far infrared radiation plate, have the hole, resistor stripe is arranged in the described hole.
As improvement, the outer surface of far infrared radiation plate is provided with insulating barrier.
As improvement, the outer surface of insulating barrier is provided with heat-insulation layer.
For any resistance far-infrared heater recited above, the far infrared radiation plate is a carborundum far infrared radiation plate.
For any resistance far-infrared heater recited above, described resistor stripe is the Aludirome resistor stripe.
The beneficial effects of the utility model: it is power-saving technology that pressure vessels for the chemical industry is carried out " far infrared " heating, and its advantage: the heating surface temperature is even, adds not coking of thermal material, good product quality; Electrothermal efficiency＞0.96, power factor Cos ф＞0.98; The heater structure floor space is little, noiselessness during operation, and free from environmental pollution, maintenance management is easy, and cost of equipment is low, uses the economic benefit height.
The contrast that " oil bath still (electrical bar) heating ", " frequency inductance should heat ", " the straight fiery heating kettle of industrial furnace " are used instead respectively after " resistance far-infrared heater " sees Table 1,2,3.
Adopt this heater to remove to substitute traditional heater (electric induction heater, electrothermal high-temperature oil heat transfer unit (HTU), be straight fiery heating furnace of fuel etc. with coal or oil) reducing energy consumption after, use the investment of the recoverable compensation reforming equipment of expense of three to 5,000 hours energy efficient.For the heating of new clothes equipment, can save the engineering fund.This heater is under normal operating position, and the life-span reached more than 30,000 o'clock.

Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described further.
Resistance far-infrared heater shown in Fig. 1, the heater block that comprises heated container (reactor) 1, is made up of carborundum far infrared radiation plate 2,0cr25A15 resistor stripe 3 and the power supply (not shown) that links to each other with resistor stripe, the insulating barrier 4 that is arranged on the outer surface of carborundum far infrared radiation plate, what be arranged on the insulating barrier outer surface is heat-insulation layer 5, and it is one deck high-temperature heat insulation alumina silicate fiber felt.
Carborundum far infrared radiation plate 2 is looped around the periphery of container 1, between the inner surface of carborundum far infrared radiation plate and the outer peripheral face of container gapped 6.Be coated with coatings capable of preventing from far infrared radiation on the inner surface of carborundum far infrared radiation plate.Have the hole on carborundum far infrared radiation plate 2,0cr25A15 resistor stripe 3 is arranged in the described hole.
According to application test, the table temperature control of carborundum far infrared radiation plate 2 is advisable at 400～550 ℃, selects 0cr25A15 high temperature resistant resistance bar for use, and its table temperature control can make hot application life reach more than 20,000 hours at＜600 ℃.
