Description
Technical field
The present invention relates to chemical industry of inorganic salt product drying technical field, refer to especially a kind of basic zinc carbonate drying device.
Background technology
The preparation method of chemical industry of inorganic salt product basic zinc carbonate is mostly as follows: the mother liquor of producing zinc salt taking zinc oxide breeze is raw material, mother liquor is warmed up to 78～85 DEG C, in constantly stirring, add sodium carbonate or carbonic hydroammonium, controlling reactant pH value is 6.0～6.5, reaction terminating, can obtain basic zinc carbonate.The basic zinc carbonate that above-mentioned chemical reaction obtains need to be after the operation such as super-dry, pulverizing, just can be packaged into product and normally sell.
The thermal energy source that tradition basic zinc carbonate drying means adopts mostly is fire coal, fuel oil or natural gas, by burning, these fuel are directly or indirectly dried basic zinc carbonate, this method often causes a large amount of energy wastes, discharge the pollution gas such as great amount of carbon dioxide, sulfur dioxide, be unfavorable for energy-conserving and environment-protective.
For example, some factory's Domestic coal-fired boiler steam of producing basic zinc carbonate is dried basic zinc carbonate indirectly, often dry one ton of basic carbonate zinc product will consume 0.7 ton of mark coal, and one ton of mark coal of every burning will discharge 2.6 tons of carbon dioxide and 8.5 kilograms of sulfur dioxide.If a factory produces 3 tons of basic zinc carbonates every day, need to discharge so 5.6 tons of CO 2 waste gas and 18 kilograms of form waste gas of sulfur dioxide every day, and carbon dioxide, form waste gas of sulfur dioxide are the main causes that forms haze weather, deviate from mutually with current energy-conserving and environment-protective policy is large.
Summary of the invention
The present invention proposes a kind of basic zinc carbonate drying device, solved that basic zinc carbonate dry run in prior art wastes energy, the problem of discharging waste gas, not environmental protection.
Technical scheme of the present invention is achieved in that
A kind of basic zinc carbonate drying device, comprising: hothouse and solar water heater, be provided with drying bed below described hothouse; Described drying bed is made up of the thermal conductive metal plate setting gradually from top to bottom, heat dissipation pipe and foam heat-insulating board; The output of described solar water heater is connected with one end of described heat dissipation pipe by hot water conveying pipe, and described heat dissipation pipe's the other end is connected with the input of described solar water heater by return duct.
As preferably, described return duct is provided with hot water circulating pump.
As preferably, described hothouse is the booth of being made up of transparent heat insulating plastic sheeting or transparent glass.
As preferably, the top of described hothouse and both sides offer respectively the window for the air guide of ventilating.
As preferably, described solar water heater is flat board-vacuum pipe solar water heater.
Operation principle of the present invention is as follows:
The basic zinc carbonate material that contains moisture is placed on the thermal conductive metal plate of the drying bed in hothouse, and material is spread out, plastic sheeting or glass that outdoor sunlight sees through hothouse top and surrounding are radiated on the upper surface of basic zinc carbonate material; Meanwhile, the hot water in solar water heater is under the effect of hot water circulating pump in the heat dissipation pipe in hot water conveying pipe enters drying bed, and the heat that heat dissipation pipe produces passes to the lower surface of basic zinc carbonate material by thermal conductive metal plate.
So just realized basic zinc carbonate material upper and lower surface and be subject to heated drying simultaneously, the moist steam producing in dry run is discharged by the window of hothouse top and both sides, has accelerated rate of drying.
Hot water in heat dissipation pipe, after overheated conduction cooling, flows back in solar water heater by return duct, and again heated, so iterative cycles, constantly carries out heat drying to the material on drying bed.
Because basic carbonate zinc product temperature under solar radiation is not high, do not decompose, after being therefore dried, can not change product quality.
Beneficial effect of the present invention is:
By the mode that adopts upper and lower surface to be heated simultaneously, basic zinc carbonate material is dried, in process, without turning over materials, has saved cost of labor.
Whole heat drying process, without fire coal, fuel oil or natural gas equal energy source, only need utilize solar energy just can realize, energy-conserving and environment-protective more.
Utilize clean energy resource solar energy drying chemical products basic zinc carbonate, have cheaply, overcast and rainyly still can carry out dry benefit.
