Technical field
Condensed water and steam exhaust recovering device in a kind of refined naphthalene production of the utility model, belong to chemical plant installations technical field.
Background technique
The production process of refined naphthalene is the refined naphthalene product that high-content is obtained by fractional crystallization technology, while will be enriched benzo-thiophene
Outside the low content naphthalene discharge battery limit (BL) of equal impurity, in the process, the melting range of all fractions is between 50 DEG C~80 DEG C, therefore
Equipment and material pipe require 0.4MPa steam and carry out heat preservation heat tracing, therefore bring condensed water and reveal the recycling of steam
Problem.
Steam exhaust is the low pressure waste vapour that can not directly use being discharged in process, it is also possible to come from the flash distillation of condensed water
Vapour.The hot water that the recycling of steam exhaust is generally used water absorption method, but produces often nowhere can be used, this be " entropy superfluous " this
Generally existing world-famous puzzle.Traditional recovery method is to bury a ground tank in device area, and a delivery pipe is set on tank, condensation
From flowing into tank, the steam exhaust of no pressure empties liquid, and this method causes the huge waste and live ring badly of exhaust steam residual heat
Border.
Full factory steam is all after releasing the latent heat of vaporization in gas utilization unit, to become condensed water, be discharged through steam trap at present.No
Condensed water with gas utilization unit discharge is pooled in water collect tank by recycling pipe network, is sent to boiler hot-water by condensate water recovery device
Tank.
But do so and there are problems that 2 need to solve: 1) each condensed water discharge point pressure is variant, results in collecting in this way
Water pot cannot be with pressure, and if there is pressure, some equipment impeded drainages may have that heat transfer phenomenon does not bring production run；
2) it is too high to be unable to back pressure for steam trap, if back pressure is high, condensed water is also caused smooth cannot to be discharged.Thus put water collect tank
It is empty necessary normally opened, bring waste of steam and site environment compromises.
Utility model content
The utility model has overcome the deficiencies of the prior art and provide condensed water and steam exhaust recycling dress in a kind of production of refined naphthalene
It sets, which is able to achieve the recycling of exhaust steam heat energy, runs condensed water effectively.

Pipeline is connect with medium temperature water pot, and a pipeline is connect with venturi-type eductors feed inlet；The discharge port of the venturi-type eductors
Connect with high temperature water pot import, the venturi-type eductors air inlet with from everywhere steam exhaust or condensed water water collect tank emptying steam
The connection of steam pipe road；
The high temperature water pot includes tank body, the first entrance for being set to top of the tank, second entrance and drain, is set to
The drain of tank base and outlet；The high temperature water pot first entrance and hot water used in system piping connection, second entrance and Wen Qiu
In injector discharge port be connected；
The high temperature water pot is additionally provided with liquid level display control warning device and temperature display controller.
The liquid level display control warning device can control the discharge of high temperature water pot and medium temperature water pot.
The temperature display controller can control the discharge of medium temperature water pot.
The water-circulating pipe road is provided with regulating valve and flowmeter.
Compared with prior art, the utility model has the advantages that
1) two kinds of purposes of set of device can eliminate heat to the heat whole recycling and reusing of system condensing water and steam exhaust
Pollution, realizes the recycling of condensed water and steam exhaust, and substantially improves work on the spot environment.
2) setting of venturi-type eductors is tiny structure, is conducive to drain valve so that drain valve back pressure is lower than original
It opens, utilidor does not have condensed water hydrops, and heat tracing effect is more preferable.
3) water at low temperature of refined naphthalene crystallizer circulation water pot, recirculated water load reduction is utilized.
Detailed description of the invention
Fig. 1 is utility model device structural schematic diagram；
In figure: 1 being high temperature water pot, 2 be venturi-type eductors, 3 be hot water circulating pump, 4 be medium temperature water pot, 12 be first to enter
