The naked tube self-drainage steam-air preheater comprises a heat exchange tube bundle and a valve set, wherein a rectification plate is arranged at an air inlet; the heat exchange tube bundle of the preheater is arranged by straight-raw tubes and is in a naked tube type; and a steam and water separator is arranged on a steam/water outlet and realizes the automatic separation of steam and water.
Description
Technical field:
The utility model relates to admittedly useless process field, relates in particular to the air-supply heating that burning city domestic garbage is handled, and is that a kind of thermal source that is applicable to is taken from the system and carried out recycling equipment.
Background technology:
Moisture content height in the domestic waste is unfavorable for burning, so the general using hot blast earlier carries out drying to the rubbish of sending in the incinerator, allows wherein water evaporates.In order effectively to utilize the heat energy that discharges behind the incineration firing, waste heat boiler is set behind incinerator generally simultaneously, produces steam-electric power.
The utility model content:
The purpose of this utility model is that existing equipment is improved.By cowling panel being set, increasing steam-water separator, adopting the naked pipe heat-exchanging tube bundle, the heat exchange efficiency of equipment integral body is increased, prolong maintenance period, and then realize energy-conservation effect.
A kind of naked pipe of the utility model comprises heat-exchanging tube bundle and valve sets from the hydrophobic type steam air heater, wherein, at air intake cowling panel is set; Forewarmer heat exchange tube Shu Caiyong vertical pipe arranges that heat-exchanging tube bundle adopts the naked pipe pattern; Outlet at steam/water is provided with steam-water separator, and steam-water separator is realized the automatic separation of steam, water.
Further, at above-mentioned air intake cowling panel, be in the inlet air compartment of preheater, to increase 1-2 piece cowling panel, air compartment is divided into 2-3 cell, cowling panel has played and has carried out the effect of rectification, guiding to going into one's intention as revealed in what one says, makes the air that enters in the preheater steady more, even.Thereby increased the heat exchange effect of preheater integral body, played energy-conservation effect.
Further, forewarmer heat exchange tube Shu Caiyong vertical pipe arranges, in the outlet of steam/water steam-water separator is set.Steam has only realizes that fully becoming saturation water after the heat release could discharge, and the consumption of steam has been saved in this kind design, realizes energy-conserving action.
Further, heat-exchanging tube bundle adopts the naked pipe pattern.What pass through outside the tube bank is the air that also has the part dust, adopts naked pipe to be not easy to make flying dust to pile up, thereby increases the time interval of keeping in repair deashing, reduces operating cost.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a structural representation of the present utility model.
The 1-cowling panel that enters the mouth; The 2-heat-exchanging tube bundle; The in line naked pipe of 3-; 4-import air compartment;
5-steam-water separator (valve sets).
The specific embodiment
A kind of naked pipe of the utility model as depicted in figs. 1 and 2, comprises heat-exchanging tube bundle 2 and valve sets 5 from the hydrophobic type steam air heater, wherein, at air intake cowling panel 1 is set; Forewarmer heat exchange tube Shu Caiyong vertical pipe arranges 3, and heat-exchanging tube bundle adopts the naked pipe pattern; Outlet at steam/water is provided with steam-water separator 5, and steam-water separator is realized the automatic separation of steam, water.
At above-mentioned air intake cowling panel, be in the import air compartment 4 of preheater, to increase 1-2 piece cowling panel, air compartment is divided into 2-3 cell, cowling panel has played and has carried out the effect of rectification, guiding to going into one's intention as revealed in what one says, makes the air that enters in the preheater steady more, even.Thereby increased the heat exchange effect of preheater integral body, played energy-conservation effect.
Forewarmer heat exchange tube Shu Caiyong vertical pipe arranges, in the outlet of steam/water steam-water separator is set.Steam has only realizes that fully becoming saturation water after the heat release could discharge, and the consumption of steam has been saved in this kind design, realizes energy-conserving action.
Heat-exchanging tube bundle adopts the naked pipe pattern.What pass through outside the tube bank is the air that also has the part dust, adopts naked pipe to be not easy to make flying dust to pile up, thereby increases the time interval of keeping in repair deashing, reduces operating cost.
By cowling panel being set, thereby reduce the equivalent diameter of each separating chamber, make the pressure reduction of separating chamber change reduce, forced the air quantity of flow area even at the inlet air compartment.The air quantity that flows through heat-exchanging tube bundle more is tending towards all even stable.
Steam-water separator is used in exit at heating source (steam/water).This kind heat transmission equipment mainly is to utilize saturated vapor to be condensed into the principle that the latent heat of vaporization that saturation water emits adds hot-air.If do not use steam-water separator, the control of steam is realized by the flow velocity of steam substantially this kind mode produces or steam does not condense into just discharging of water as yet fully through regular meeting, causes the waste of heat and the load of subsequent processing device to become big; Liquid level in the heat-exchanging tube bundle is raise, heat exchange is worsened, influence whole heat exchange effect, not reach expected effect.After steam-water separator was set, when the air capacity by flow area changed, the flow of steam was followed automatic adjustment, and when the air capacity of passing through increased, the heat exchange amount that needs also can increase, and the amount of condensed water can be discharged thereupon increasing; When the air capacity of passing through reduced, the heat exchange amount that needs reduced, because of the still uncooled one-tenth water of steam can't be discharged.Realize making full use of of heat in this way, saved the consumption of steam, reduced the load of oxygen-eliminating device/condenser simultaneously.Reached energy-conservation effect.
Heat-exchanging tube bundle adopts in line layout, the naked pipe pattern.This kind heat exchanger is because of being usually used in the burning city domestic garbage industry; need the wind routine of heating to take from the top or boiler room of dump pit; air contains a certain amount of dust and moisture; if adopt extended surface tube or screwed pipe; can pile up dust in the windward side; and influence the heat exchange effect, and may cause the obstruction of wind passage when serious, have to shut down cleaning and safeguard.Adopt naked pipe, in line layout to solve above-mentioned drawback basically.
Realized by above three kinds of measures: the fouling phenomenon that effectively reduces the heat-transfer surface surface; Make air intake even, increased the heat exchange effect; Realize the automatic separation of steam, reached energy-conservation effect.
