Abstract
The present invention relates to a heat source supply method for a shellac bleaching process. In the method, a solar heating system is used for providing a heat source for a shellac dissolving alkali solution, and an electric heating furnace is used as an auxiliary heating device; hot water heated by a solar energy vacuum heater flows into the electric heating furnace and a thermostatic water tank; when a water temperature is controlled at 80 to 90 DEG C, and a valve is switched on to make hot water at a proper temperature flow into a shellac dissolving device; after shellac is dissolved for 1 to 2.5 hours, impurities in a shellac dissolving solution are filtered by a filter; the filtered shellac dissolving solution enters a heat exchanger to carry out heat exchange by using tap water as cooling water, cold shellac dissolving solution below 40 DEG C is delivered to the next step, and cooling water flows in the solar heater to be recycled. The present invention has the advantages that energy can be effectively saved, and cost can be reduced.
Description
Technical field: the present invention relates to the power supply method in the processing, especially a kind of thermal source supply method of bleached shellac processing.
Technical background: in the bleached shellac complete processing, at first shellac to be dissolved in the buck about 80 ℃, impurity screening then, the cooling cooling is bleached, operations such as dewaxing, crystallization again; The required thermal source supply method of existing heating is to adopt boiler to produce superheated vapour to heat buck, or heats buck with electric heater unit.Above-mentioned heating means all will expend a large amount of energy, only allow in the city at present to adopt oil-firing boiler, with 1 kilogram/cm
3Oil oven calculate, starting boiler needs 60 kilograms of diesel oil, every operation needed 50 kilograms of diesel oil in 1 hour, energy consumption is huge, production cost rises; In addition, boiler has a large amount of waste gas, waste water to discharge, and noise is bigger, pollutes to environment; Simultaneously, adopt boiler to produce hot steam, warm-up time is longer, also needs full-time skilled worker and operates boiler, influences production efficiency and waste of manpower resource.
Summary of the invention: the objective of the invention is to change the power supply method in the shellac processing, a kind of thermal source supply method of bleached shellac processing is provided, it adopts solar heating system to provide thermal source for the colloidal sol buck, be aided with electrothermal oven thermostatically heating equipment, can effectively play save energy, reduce cost, improve the effect of environment.
Technical scheme of the present invention is: the hot water through solar energy evacuated heater heats enters in electrical heater and the constant temperature water tank, when control water temperature is 80-90 ℃, Open valve enters in the peptizer hot water of suitable temp, after colloidal sol 1-2.5 hour, sol solution filters out impurities through filter, enter interchanger and do water coolant with tap water and carry out heat exchange, 40 ℃ the cold glue liquid of being lower than that obtains is sent into subsequent processing, and the water coolant after the heat exchange enters into solar energy evacuated well heater and recycles.In the described electrically heated constant temperature water tank thermal sensor element is housed.
Description of drawings: Fig. 1 is a process flow sheet of the present invention.
Embodiment is illustrated in conjunction with the accompanying drawings.
The present invention adopts solar energy evacuated well heater for the colloidal sol buck provides thermal source, is aided with electrothermal oven thermostatically heating equipment, and adopts interchanger to carry out heat exchange.Calculate as per diem processing one ton of shellac, need 80 ℃ of hot water 5-6 tons.By 15 ℃ of calculating of basic water temperature, 1 ℃ of heat requirement 1 kilocalorie of 1 kg water intensification, every valve tube capacity is 25 liters, under normal in the winter time sunshine, produces 1200 kilocalorie heats, adopts 170 valve tubes to satisfy the demand fully.
Adopting the 60KW electric boiler is boosting equipment, can in 1 hour temperature be improved 10 ℃, can guarantee round-the-clock use hot water.
Because shellac behind heating for dissolving, impurity screening, need be reduced to temperature below 40 ℃.Therefore adopt plate-type heat exchanger to carry out heat exchange, on the technology, the water coolant after the heat exchange sent in the solar heating system recycle, make basic water temperature bring up to 40 ℃, make solar energy system shorten heat-up time, temperature improves.
As shown in the figure, open valve 1, valve-off 2, this moment, tap water entered in the solar energy evacuated well heater, to cyclic water tank when full, valve 1 is closed, because the heat power effect, water is constantly circulation heating in system, use the hot water front opening hot water enter in the electrical heater constant temperature water tank, in the electrically heated constant temperature water tank thermal sensor element is housed, when water temperature was lower than 80 ℃, electric heater unit was started working, and cut off the power supply automatically during to 80 ℃, when the hot water temperature of solar energy system is higher than 90 ℃, thermal sensor element sends signal, and tap water electronically controlled valve 5 is opened, and enters cold water in the electrically heated constant temperature water tank, water valve 5 cuts out from the beginning when temperature is lower than 90 ℃, guarantees that water temperature in the constant temperature water tank is between 80-90 ℃.Open valve 4, the water of optimal temperature enters in the peptizer, adds raw material, and colloidal sol is finished after about 2 hours, and sol solution filters out impurities through filter, enters interchanger, does water coolant with tap water, by heat exchange, hot glue liquid is become＜40 ℃ cold glue liquid.Simultaneously, the coolant water temperature after the heat exchange rises to 40 ℃, and open valve 2 this moment, and water coolant enters into solar energy system, serves as the sun power water source.Obviously because basic water temperature is brought up to 40 ℃, therefore, the solar heating time also shortens dramatically.
In total system, valve 1 is a normally open solenoid valve, valve 2 be normally closed solenoid valve and with interchanger interlock, valve 1 and 2 interlockings, and valve 1 and 2 is controlled by the cyclic water tank water level simultaneously, valve 3 is normally closed, and controlled by the water temperature of constant temperature water tank, and valve 3 and valve 5 interlockings, all valves of total system all use magnetic valve, concentrate on the peptizer operator's console, finish by colloidal sol operation staff.
The cyclic water tank that uses in the present embodiment, electrothermal oven thermostatic control water tank all adopt silicate to make lagging material, can keep 60 tons of 80 ℃ of hot water only to descend 3-5 ℃ in one day.
The present invention compares with existing method has obvious good effect:
1, saved a large amount of energy, but processed 170 kilograms of one ton of shellac capable of saving fuel oils, by producing 300 per year Ton calculates, 51 tons of capable of saving fuel oils, the corresponding freight of having saved simultaneously fuel oil.
2, need not full-time skilled worker and operate, only need to finish by the part-time staff.
3, improved the security of producing.
4, owing to use clean energy, avoided waste gas, the discharging of waste water, noiselessness pollutes.
