Water Drying By High Efficiency Infrared Radiant Heat Lamps

Water Drying By High Efficiency Infrared Radiant Heat Lamps

Traditionally, water drying processes usually use combustion fuels or electricity for heating, and the external objects are heated to generate heat and transfer it to the material through convection of hot air or thermal conduction, so that the water in the material can absorb heat to achieve the purpose of drying. However, traditional combustion fuels, such as natural gas, liquefied gas, coal, wood, etc., are non-renewable resources, and the combustion process emits a lot of pollutants; the heat loss is large, the energy use efficiency is low, and the drying time is long. Therefore, the use of infrared radiation heating to dry water has become a new way of industrial cleaning and efficient heating.Traditionally, water drying processes usually use combustion fuels or electricity for heating, and the external objects are heated to generate heat and transfer it to the material through convection of hot air or thermal conduction, so that the water in the material can absorb heat to achieve the purpose of drying.

Steel Paint Drying By Infrared Heating Lamp

Steel Paint Drying By Infrared Heating Lamp

Infrared heating technology is to use the principle of electromagnetic radiation heat transfer, the infrared radiation does not need to contact heated objects and does not require intermediate medium to transfer heat, direct heat transfer to heated objects. And our quartz infrared heating has high energy density, strong penetration, fast response, and good temperature controllability. Therefore, quartz infrared heating technology is widely used in printing, textile, semiconductor, glass, electronics and other industrial drying.     Especially in the paint coating drying, infrared rays have strong penetration, they can be absorbed by the particles and coating substrates inside the coating at the same time, from inside to outside or simultaneously heating the coating. Avoiding coating bubbles, shells or wrinkles phenomenon with a faster and higher quality drying coatings. Infrared heating can be placed horizontally or vertically around the coating, take up less space, save equipment costs.     Let us start from the following paint drying requests for steel by infrared quartz lamps. Dear Sir, we are looking at Electric- Infrared Tubes (Explosion-Proof Type) 3.0m length x 0.4m width x 0.2m height for direct heating of painted steel plates from 26C to 80C inside a heating cabinet while the steel plates are moving at the speed of 1.5 ~ 2.5m/min. Power is 415V/3Ph/50Hz. The Paint Drying Cabinet Size: 3.2m Width x 9m Length x 1m Height with airflow of 290cu.m/min generated by centrifugal fan. Can you recommend the number of Infrared Tubes required to achieved 80C inside the cabinet based on the specified air-flow (exhausted out).       1: What is the heated object for the above request? The painted steel plate.   2: What type of quartz infrared heating is good for the painted steel plate? Steel materials absorb 0.76-2um infrared radiation better, so shortwave quartz infrared heating or Fast response mediumwave infrared heating are reasonable for meeting drying purpose.   3: How to distribute quart infrared heating for the steel coating drying? The quartz lamps of infrared heating system are distributed along the running steel plate, installed on the upper and lower sides of the steel plate, or the left and right sides. The lamps of infrared heating system need to be divided into different heating groups and each heating group can be switched on and off and temperature controlled separately to meet the heating needs of different width steel plate.   4: What factors should be considered when designing lamp power? Heating temperature, this is an important factor to design the heating power, and all quartz heating lamps should be controlled by PLC or SCR to adjust the heating temperature in the drying oven. Coating thickness and plate thickness, more thicker plate needs more heating power and we should calculate the biggest thickness plate as an important factor. Plate width, this will be an important factor to design the heating length of each quartz infrared lamp and width of heating lamps group. Plate speed, this is an important design factor, we have to calculate the heating time from entrance to exit and meanwhile the heating temperature can be raised up in the heating time. Plate color, different colors have different efficiency of infrared absorption. The darker the color, the higher the infrared absorption efficiency; the lighter the color, the lower the infrared absorption efficiency. Therefore, the color changes of the steel plate need to be considered in designing of lamp power. air intake or exhaust flow, air into or out of drying oven will have a certain impact on the heating temperature, in order to make steel plate heating temperature more uniform, we need to consider this factor. Other environmental factors, seasonal temperature changes, the heat preservation effect of drying oven.

What exactly is the method of infrared lamp Paint drying

What exactly is the method of infrared lamp Paint drying

Infrared lamp paint drying is to use a light source that can emit energy in a very narrow wavelength range to heat the coating film that can absorb radiation in this wavelength range. Organic molecules in the coating absorb energy, prompting molecular atoms or groups to vibrate or rotate, thereby increasing the energy inside the substance, inducing physical and chemical changes in the substance, and drying the coating.

The gold reflector difference between quartz infrared heater lamps

The gold reflector difference between quartz infrared heater lamps

In order to better convey and focus on the heated material all the IR radiation emitted from quartz heater lamp, the special gold reflector or white reflector will be coated and fixed directly on the quartz surface. The use of a coating reflectors on IR heaters will obtain an additional increase of the IR radiation energy to the heated materials. So the heating efficiency and drying process time will be faster than quartz infrared heater lamp without any reflect layers.   Let us see the following video to feel the heating temperature on reflect layer side and without gold layer side.     We can obviously feel the heat in the direction of the infrared heating, but the heat is very low in the direction of gold coating. This is because the gold coating reflects more infrared radiation back to the direction of heating. We can also confirm the above views through test temperature data and temperature rising trends.   380V 7500W 2500mm Medium Wave Twin Tube Quartz IR Lamp Without Reflector Heating time 0s 10s 20s 30s 40s 50s 60s 90s 2mins 2m 30s Surface temperature 9℃ 35℃ 68℃ 120℃ 180℃ 230℃ 280℃ 400℃ 477℃ 520℃ Heating time 3m 3m 30s 4min 4m 30s 5min 5m 30s 6min       Surface temperature 544℃ 558℃ 567℃ 575℃ 580℃ 582℃ 585℃

What is the response time of medium wave quartz infrared heater

What is the response time of medium wave quartz infrared heater

The response time of medium wave infrared quartz heater is 1-4minutes, the emitters can provide constant and uniform infrared heating when they run stably. Let us take clear quartz infrared heater of 7500W 2500mm toatl length with 2300mm heated length as example.                                                                                                                                                                                                                                                                                                                                                                                                                      The temperature are tested in an open environment, the surface heating temperature will be higher than 580℃ in the drying oven.   Medium wave quartz infrared emitters are particularly suitable for the fast heating of surface or thin materials, and the range of IR radiation wavelength is 2.2-4.0μm. Meat, herbs, fruits, vegetables and other food in life, paints, plastics sheet or film, water and other solvents in industry, all of their drying processes can absorb well this medium wave infrared radiation. Because of its long working life and economic efficiency, medium wave infrared emitters are popular used in continuous heating processes and long drying machine or drying oven.
