Description
Technical field
The utility model relates to the technical field of paper making equipment aspect.
Background technology
Energy-conservation and environmental protection is the important topic that the present age, the whole world was paid close attention to, and energy savings, raising energy utilization rate have been classified fundamental state policy as in national Eleventh Five-Year Plan outline.Energy-conservation concerning enterprise the most direct income be exactly cost saving expenditure, increase economic efficiency, enhance one's market competitiveness.
Waste heat is meant and can utilizes and unemployed heat energy.Because China is industry a lot: as industries such as chemical industry, petrochemical industry, building materials, light textile, metallurgy, power, food, papermaking, electronic apparatus, the direct emptying of a large amount of heat energy is arranged aborning, not only wasted energy but also contaminated environment.Waste heat recovery is exactly the heat energy recycle with waste, improves energy utilization rate, reduces production costs the protection environment.
The existing gram gas hood of raising generally is applied to paper industry, but the existing gram gas hood of raising exists the moisture diffusion of paper insufficient, and thermal efficiency ratio is lower, and energy consumption is than higher.
The utility model content
The utility model purpose aims to provide a kind of novel gram gas hood of raising, and this raises the gram gas hood can make the diffusion of paper abundant, and rate of drying is fast, thermal efficiency height, and energy consumption is low.
For achieving the above object, the technical solution adopted in the utility model is: a kind of novel gram gas hood of raising, comprise the fan housing shell, described fan housing shell is inserted heat preservation fibre glass cotton, described fan housing shell middle part is the air channel ventilation terminal, the external V-type blowing mouth of described fan housing shell, the described gram gas hood end of raising is blowing pipeline and return air duct.
Described a kind of novel gram gas hood of raising,, described fan housing shell is outward the thick corrosion resistant plate spot welding of 1.5mm.
Described a kind of novel gram gas hood of raising, described V-type blowing mouth are V-type spray seam formula blowing mouths, and the width of its seam mouth is the 2-4 millimeter.
Described a kind of novel gram gas hood of raising, described V-type blowing mouth are V-type spray seam formula blowing mouths, and the distance of its spray plate or spray seam and paper is at the 10-35 millimeter.
Described a kind of novel gram gas hood of raising, this is raised between each nozzle box that restrains gas hood and is the exhaust passage all around.
Described a kind of novel gram gas hood of raising, this is raised the gram gas hood and is provided with steam heater.
Described a kind of novel gram gas hood of raising, this is raised the gram gas hood and is provided with heat-conducting oil heating or combustion gas heating.
Described a kind of novel gram gas hood of raising, this is raised the gram gas hood and is installed in paper machine oven dry portion leading portion.
This raises the gram gas hood is the leading portion that is contained in oven dry portion, and this position paper moisture diffusion is comparatively abundant, and the winding-up of high speed hot blast can not influence into the quality of paper.When Dryer Section of Paper Machine install the invention of my company raise the gram gas hood after, its rate of drying than common high 4-7 doubly, thermal efficiency 85%-92%, the waste gas water capacity very high (0.2-0.25 kg/kg air) so the fresh air make up of discharging from air bells cap greatly reduce (about 10%), and energy consumption is low than traditional ventilating system also.With same drying cylinder number.When load onto raise gram cover after, drying cylinder production capacity will be improved greatly.Water evaporates in the paper that makes speeds up.Between each nozzle box and then be the exhaust passage all around.Outdoor fresh air is delivered to waste-heat recoverer through first blower fan and is reclaimed heat, heater via is heated to about 120-400 ℃ again, (can reach 400-500 ℃) with conduction oil or combustion gas heating, send into gas hood then, blow to the wet paper surface by the spray seam, owing to the water capacity height of air in the later half cover, control the mass dryness fraction of air quantity or paper again through control valve.
Description of drawings
The structural representation of Fig. 1 the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, a kind of novel gram gas hood of raising comprises fan housing shell 1, fan housing shell 1 is inserted heat preservation fibre glass cotton, described fan housing shell 1 middle part is the air channel ventilation terminal, described fan housing shell 1 external V-type blowing mouth 4, and the described gram gas hood end of raising is blowing pipeline 2 and return air duct 3.Outside the fan housing shell 1 is the thick corrosion resistant plate spot welding of 1.5mm.V-type blowing mouth 4 is V-type spray seam formula blowing mouths.Described V-type blowing mouth 4 is V-type spray seam formula blowing mouths, and the width of its seam mouth is the 2-4 millimeter.Described V-type blowing mouth is a V-type spray seam formula blowing mouth, and the distance of its spray plate or spray seam and paper is at the 10-35 millimeter.This is raised between each nozzle box that restrains gas hood and is the exhaust passage all around.This is raised the gram gas hood and is provided with steam heater.This Yang Keqi has set up electric heater.This is raised the gram gas hood and is installed in paper machine oven dry portion leading portion.
A kind of novel gram gas hood of raising is made up of fan housing shell, corrosion resistant plate, blowing pipeline, air channel ventilation terminal, " V " type blowing mouth, heater, return air duct.This raises the gram gas hood is skeleton with the square steel.The fan housing shell is inserted heat preservation fibre glass cotton and is played insulation effect, the outer thick corrosion resistant plate spot welding of 1.5mm of fan housing shell, and fan housing shell middle part is the air channel ventilation terminal, and external " V " type blowing mouth is blown, and it is terminal for sending the exhausting road junction that this raises the gram gas hood, and one send one time.Air outlet is sent wind into the air channel ventilation terminal by the air-supply corridor, will be sent on the drying cylinder page to hot blast by " V " type tuyere and carry out the removal moisture drying processing when the blast of air channel ventilation terminal reaches certain value.The used heat that return air inlet will contain moisture is extracted into end-equipment and carries out after-treatment.
The utility model mainly is by the blowing of V-arrangement spray seam formula tuyere, seam mouth width 2-4 millimeter, and the distance of spray plate or spray seam and paper is between the 10-35 millimeter.Guarantee that wind direction is positive 70 degree, makes that the water evaporates in the paper web speeds up.Between each nozzle box and then be the exhaust passage all around.Outdoor fresh air is delivered to waste-heat recoverer through first blower fan and is reclaimed heat, enter heater then, heater via is heated to about 120-400 ℃ again, send into gas hood then, blow to the wet web surface by the spray seam, owing to the water capacity height of air in the later half cover, therefore control the mass dryness fraction of air quantity or paper web with control valve.Raising the gram gas hood is the leading portion that is contained in oven dry portion, and this position paper web moisture diffusion is comparatively abundant, and the winding-up of high speed hot blast can not influence into the quality of paper.When Dryer Section of Paper Machine install the invention of my company raise the gram gas hood after, its rate of drying than common high 4-7 doubly, the thermal efficiency is brought up to about 85%, the waste gas water capacity very high (0.2-0.25 kg/kg air) so the fresh air make up of discharging from air bells cap greatly reduce (about 10%), and energy consumption is low than traditional ventilating system also.When load onto raise gram cover after, drying cylinder production capacity will be improved greatly.Raise the utilization of gram gas hood and can bring into play huge benefit aspect the energy-conservation province material for paper industry; Reduce this equipment energy consumption simultaneously in the reduction that guarantees the page cost.
