Abstract
The present invention the goal is to provide a kind of asphalt production line heating conduction oil heat-exchanger rig, for asphalt production workshop heating equipment heat-conducting oil heating heat, including RTO(heat accumulating burner), conduction oil heat exchange coil, head tank, circulating heat conduction oil pump.Advantage is: while saving equipment investment cost, it is exchanged heat using the burner hearth heat of heat accumulating burner to the conduction oil in production process, so as to reduce the use in production process to boiler, since the heat exchange efficiency of regenerative chamber burner can reach 95% or more, therefore use of the production process in pitch to boiler, the purpose of realization saving energy consumption and clean manufacturing be can reduce again while solving the problems, such as waste gas purification.
Description
Technical field
The present invention relates to modified tank in asphalt production process and storage tank heat fields, and specifically a kind of asphalt production line heating is led
The heat-exchanger rig of hot oil.
Background technique
Asphalt modification tank and raw material storage tank etc. need heat-conducting oil heating during asphalt modification processing.It is big at present
The mode that multi-pass crosses boiler heating conduction oil heats asphalt mixing and raw material storage tank, heats the boiler mesh of conduction oil
It is preceding mainly to have biomass boiler, coal-burning boiler, gas fired-boiler；The process of boiler heating can generate a certain amount of contaminated off-gas, although
Using gas fired-boiler can reduce pollution exhaust gas discharge but boiler used at present there are chimney breast temperature height exist it is certain
Security risk, while the temperature of boiler exhaust mouth has that heat loss is larger up to 400 DEG C.Therefore, how one is provided
Kind of energy utilization rate is higher, hot oil heater that is easy to operate while can realizing clean manufacturing be industry urgently
It solves the problems, such as.
Summary of the invention
According to problems of the prior art, the present invention is the goal is to provide a kind of energy utilization rate is higher, operation side
Just easy to operate, while can realize the hot oil heater of clean manufacturing.
Technical solution of the present invention content are as follows: a kind of heat-exchanger rig of asphalt production line heating conduction oil, including RTO(accumulation of heat
Formula burner), conduction oil heat exchange coil, head tank, circulating heat conduction oil pump；It is characterized in that, the conduction oil heat exchange coil
It is installed on RTO(heat accumulating burner) combustion chamber, the drip of the conduction oil heat exchange coil oil inlet and asphalt production line
Conduction oil coil pipe outlet in the heating equipments such as green modified tank (or storage tank) is connected, connecting pipe one oil pump of series winding, and is arranged
One shut-off valve and a temperature sensor, while being connected by a threeway with the bottom of head tank, it is set in connecting pipe
A shut-off valve is set, the conduction oil heat exchange coil oil outlet and the asphalt modification tank (or storage tank) of asphalt production line etc. are set with heat
Standby conduction oil coil pipe import is connected, and a shut-off valve is arranged in connecting pipe, while passing through the top of a threeway and head tank
Portion is connected, and a shut-off valve is arranged in connecting pipe.
The RTO(heat accumulating burner), be by by traditional RTO(heat storage type combustion emission-control equipment) combustion
Burn room to be transformed, conduction oil coil pipe heat exchanger be installed on RTO(heat accumulating burner) in combustion chamber, coil pipe is around burning
Indoor furnace wall is arranged, and coil pipe and burner hearth is made to have biggish contact area.Pass through improved RTO(heat storage type combustion exhaust gas
Processing unit) burner rating W=RTO(heat storage type combustion emission-control equipment) processing exhaust gas needed for power W1+ conduction oil
Power W2 needed for heating, by RTO(heat storage type combustion emission-control equipment) about 25 DEG C of exhaust inlet temperatures, chamber temperature is
760 DEG C -850 DEG C, outlet temperature is about 65 DEG C, and temperature-resistant (to useless before and after transformation with equipment export after transformation before transformation
The heat loss of the RTO of gas processing system does not have larger impact), it is 250- compared to heat transfer oil outlet temperature is heated with traditional boiler
Heat loss substantially reduces for 400 DEG C.Therefore generally speaking improved RTO device and subtracts while solving environmental issue
Use of the production process to boiler is lacked, has been reduced in the operational process of production and environmental protection equipment again while reducing cost of investment
Energy consumption.
The conduction oil heat exchange coil, material use boiler steel or stainless steel, the conduction oil heat exchange coil oil inlet
It mouthful exports and to be connected with the conduction oil coil pipe in the heating equipments such as the asphalt modification tank (or storage tank) of asphalt production line, connecting pipe string
An even oil pump, and a shut-off valve and a temperature sensor are set, while passing through the bottom phase of a threeway and head tank
It is connected to, a shut-off valve, the asphalt modification of the conduction oil heat exchange coil oil outlet and asphalt production line is set in connecting pipe
