(1), general introduction:
Product workshop smallclothes pre-treatment degreasing bath, descaling bath, phosphatization groove need heating, adopt and each groove of pre-treatment is heated with 6 tons of horizontal boilers, boiler operatiopn expense in 2005: 9.8 ten thousand yuan of labour costs, coal take 450,000 yuan, 12.2 ten thousand yuan of the electricity charge, 20,000 yuan of maintenance costs, 0.25 ten thousand yuan of annual test expense, add up to 69.25 ten thousand yuan, thermal loss when adding remote conveying the, comparatively waste.According to the different situation of the different period electricity prices of commercial power, change mode of heating into heat storage boiler+solar energy+fuel oil baking room waste gas heating.
(2), job requirement:
The degreasing bath water temperature requires to be not less than 15 ℃ (needing interrupted heating general winter), and it is 50 ℃-60 ℃ that descaling bath requires operating temperature, and it is 35 ℃-45 ℃ that the phosphatization groove requires operating temperature.Utilize at 23 in evening to next day early between 7:00 paddy electricity (0.32 yuan of electricity price) with heat storage boiler the interior water of hot water storage tank (80 cubes) is heated to 90 ℃-100 ℃.Early 8 o'clock to 11 o'clock, 2 pm to afternoons 7 point, boiler quits work, utilize in the hot water storage tank water by 6 groups of heat exchangers in each groove with the trough inner water heat exchange, need carry out pickling, phosphatization every day to 20 baskets (1000 * 2000 * 1500) workpiece.
11-3 month in winter: approximately per hour can make falling about 5-10 ℃ in the groove under water, degreasing bath, descaling bath, phosphatization groove need replenish 7,680,000 kilocalories of heats every day so.Store heat is 5,440,000 kilocalories in the hot water storage tank, adds 23.6844 ten thousand kilocalories of waste-gas heats, and the solar energy fine day can produce 10 tons of 90 degree hot water, produces 900,000 kilocalories of heats.Each groove is if install lagging facility additional every night, and temperature decline is 5-10 ℃ in the groove, and heat storage boiler makes the water in the hot water storage tank be heated to 95 ℃ from about 50 ℃ every night.Just 80 cubes of coolant-temperature gages are raise 40 ℃ with the heating of 465kw boiler.Need 1190 yuan of expenses so every day.It is 180kw that the electrical heating heat storage boiler can be selected power.
15-November 15 March: coal-burning boiler only needs to supply gas the morning to pickling, the heating of phosphatization groove only to smallclothes pre-treatment air feed in 5-9 month basically every day.Need not start coal-burning boiler afternoon, uses heat storage boiler so instead, can satisfy the production needs fully.Daytimes two, groove calculated (each groove is carried out insulation) by 5 degree that descend in decline 5-10 degree, evening, needed electricity consumption 700 degree (summer, 80 cubes of hot water were heated to 95 ℃, about available 3-4 days) so every day, needed the electricity charge of 200-300 unit every day.
After installing solar energy system additional, can be at fine day to the water in catch basin heating, 33 LPC47-1550 type power promise vacuum tubes (totally 1650) articulated solar energy heating unit, about 160,000 yuan of expense, but about 10 tons of 50 ℃ of-90 ℃ of hot water of output every day in winter; In addition, smallclothes fuel oil baking room, every day, amount of fuel was 300 liters, and the flue gas that can utilize discharge is to heat storage tank heating (as long as the phosphatization workpiece just need be opened the fuel oil baking room), and available heat is 23.6844 ten thousand kilocalories, can make 44 cubes of water rising 5 degree.Also switch to flue gas after at 4 in afternoon to the heating that directly circulates of each groove.
Integrated cost compares:
