Description
Technical field
The invention belongs to the heat-exchange apparatus in the plant equipment field, especially relate to a kind of by carrying out exchange heat to obtain the steam generator of steam with conduction oil.
Background technology
Industry at present, civilian demand to steam are increasing, major part all adopts coal-burning boiler to produce steam in the prior art, need expend a large amount of coal resources, and its thermal efficiency is lower, the long-term use in the boiler of back can produce a large amount of dust stratifications, need spend a large amount of manpowers to clear up; Also favourablely carry out heat exchange with the waste heat that produces in the industrial processes and produce steam, but this type of heat exchanger effectiveness of equipment, technology that produces steam is low in the prior art, the heat energy utilization rate is low.
Summary of the invention
The objective of the invention is to design the steam generator of a kind of heat energy utilization rate height, production efficiency height, safe ready.
The technical scheme that realizes above-mentioned purpose is as follows: steam generator, has a housing, housing is provided with oil-in, oil-out, water inlet, dewatering outlet, steam (vapor) outlet and manhole, the housing below is provided with sewage draining exit, be provided with tube sheet in the housing, be fixed with the tube bank that constitutes by heat-conducting oil pipes on the tube sheet with oil-out, oil-in UNICOM.Manhole is used for the people can enter into enclosure interior inspection, maintenance by this device;
Water inlet is arranged on housing one side near oil-in.So design makes the water that enters evaporimeter and the temperature difference maximum between conduction oil, guarantees can produce under the same condition quantity of steam of maximum.
Housing sidewall is provided with brine outlet.Brine outlet is after the high temperature of conduction oil is passed through in water inlet, has produced the impurity that does not partly meet the boiler water quality index, can discharge evaporimeter by this outlet;
Housing is provided with the water separator that is connected with steam (vapor) outlet.The moisture content that can guarantee the steam that comes out from steam (vapor) outlet meets the requirements.
The housing top is respectively arranged with safety valve, liquid level sensor, liquid level gauge, Pressure gauge.
The pipeline that is connected with water inlet is provided with the electrical shunt valve by liquid level sensor control.The electrical shunt valve is controlled by liquid level sensor.Liquid level by evaporimeter is controlled the flow that enters evaporator feedwater automatically, guarantees the level stability of evaporimeter.
Be provided with emergency shutdown valve on oil-in and the pipeline that oil-out is connected.If high-temperature hot oil side and steam side are scurried mutually in the housing, conduction oil pressure raises rapidly, and the both sides emergency shutdown valve can cut off automatically to guarantee safety.
The pipeline that is connected with oil-in is provided with the electrical shunt valve.Can be by the pressure on the evaporator shell (Pressure gauge can show) thereby thereby the switch of regulating electric T-shaped valve automatically regulate and enter behind the oil-in output of the flow steam regulation of conduction oil in the heat-conducting oil pipes.
Also be provided with conductivity measurement on the housing.Can control the process of steam generator blowdown automatically according to the size of electrical conductivity.
Housing is provided with antivoid valve.
Residue scoot, wood chip, wood shavings, branch bar, the bark of China's timber processing, and the byproduct stalk of agricultural production etc., be very abundant biomass energy.In industries such as various wood-working factories, food, bio-fuels, need a large amount of heats (medium is a steam) to be used for defibrator.The high temperature heat conductive oil that waste heat in residue scoot, wood chip, wood shavings, branch bar, bark and the heating center of the processing of organic heat carrier furnace burn wood is produced is a heat transfer medium, enters the heat-exchanging tube bundle of steam generator, and the water heating is produced steam.
According to the present invention of technique scheme, the steam boiler floor space is little relatively, operation easily, maintenance; Steam pressure control is reliable and stable, controls automatically by the electric three passes flow divider on the pipeline and enters the conduction oil flow of tube bank, and the steam pressure fluctuation is very little, generally can be controlled at ± 0.2Mpa; Heat transfer efficiency is higher, need spend long time to remove to clear up the dust stratification of fume side unlike steam boiler in the use; High-temperature region at deep fat is provided with water inlet, makes the temperature difference maximum of whole steam generator, guarantees can produce under the same condition maximum quantity of steam; Be provided with liquid level sensor and show and continuous condensate tank of dehumidifier as water level, chain with the electrical shunt valve on the inlet pipeline, guarantee the stable of steam generator water level; Be provided with the tester of electrical conductivity, can control the process of whole steam generator blowdown according to the size of electrical conductivity automatically; Be provided with emergency shutdown valve, if high-temperature hot oil side and steam side are scurried mutually, conduction oil pressure can raise rapidly, and the both sides emergency shutdown valve can cut off automatically.
Beneficial effect of the present invention is: output, the quality of steam are guaranteed; The pressure stability of steam, safe; Operation, easy to maintenance; The thermal efficiency is higher.
