It is connected, 2# heat exchanger is also connected with 1# steam generator, and 1# steam generator is connected with 2# steam generator；Head tank passes through 1#
Heat exchanger, 2# heat exchanger, 3# heat exchanger and 4# heat exchanger are connected with heating furnace.
For destilling tower tower bottom oil after 1# heat exchanger and raw material heat exchange, it is still very high to send temperature outside, after increasing heating water tank,
The temperature that tower bottom oil can be further decreased makes it send temperature reduction outside, reduces the risk of spontaneous combustion.Cold water enters from cold water outlet to be adopted
Warm water tank can meet heat supply in winter demand, increase the utilization rate of heat from hot water mouth after absorbing heat into heating installation,
And the energy consumption for reducing heating, has saved cost.
Raw material through 1# heat exchanger, 2# heat exchanger, four heat exchangers of 3# heat exchanger and 4# heat exchanger heat exchange after, further inhale
Heat has been received, temperature is improved, has reduced the consumption of fuel gas.
The 1# steam generator is connected in series by pipeline and 2# steam generator, and pipeline is equipped with 1# control valve.
It is additionally provided on pipeline between the 1# steam generator and 1# control valve and sends pipeline outside, send pipeline outside equipped with 2#
Control valve.
The heating furnace is connected with destilling tower.
It is connected in the middle part of the destilling tower with 3# heat exchanger.
The destilling tower top is connected with 4# heat exchanger.
Destilling tower lower part side line is fuel-displaced, and through 2# heat exchanger, temperature is still very high after heat exchange, passes through 1# steam generator and 2#
Temperature, which can reach, after steam generator sends temperature outside, and two steam generators considerably increase the quantity of steam of device, in 1# steam
Generator and 2# steam generator connecting pipe road are additionally provided with and send pipeline outside, and after 1# steam generator, oil temperature has reached
To temperature is sent outside, then the 2# control valve sent outside on pipeline can be opened, 1# control valve is closed, no longer pass through 2# steam generation
Device avoids because consuming energy caused by 2# steam generator working efficiency is low when oil temperature is low.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) the utility model improves the feeding temperature of raw material, reduces device fuel gas by increased heat exchanger
Consumption.
(2) the utility model increases the quantity of steam of device, improves the utilization of heat by increasing steam generator
The producing steam ability of rate, device is improved by original 4 ton/hours to 6 ton/hours, is sufficiently sent side line outside heat source and is taken out.
(3) heat of tower bottom oil is sufficiently recycled, is supplied for plant area's winter by increasing heating water tank by the utility model
It is warm to provide guarantee, the temperature that tower bottom oil is sent outside is not only reduced, but also saved energy consumption, reduced costs.
