Description
Technical field
The utility model belongs to agricultural product and heats, dries the firing equipment field providing heated dry air, is specifically related to a kind of heat-exchange device being provided with mixing bunker.
Background technology
Heating in agricultural production, dewater, drying is conventional technique, needs to use the firing equipment that can provide heated dry air frequently in technical process.The heat exchanger of existing firing equipment has 16 groups of radiating tubes, and becomes a line longitudinally to arrange one by one in a heat exchanger, as shown in Figure 1.Radiating tube in heat exchanger and radiating fin arrange comparatively tight in interchange channel, air is relatively short by the time of interchange channel, cause rate of heat exchange not high, and water to steam in place radiating tube be all co-flow from top to bottom, the temperature potential of radiating tube must form the situation that height bends down, just cause interchange channel upper, middle and lower layer of air excessive temperature differentials, be unfavorable for the abundant exchange of heat.Therefore also there is combustion heat exchange abundant not, expend excessive fuel, the shortcomings such as cost is higher.Therefore need by transforming existing heat exchanger, to improve heat exchanger effectiveness, to meet the needs of production.
Utility model content
The utility model, for the deficiencies in the prior art, provides the heat-exchange device being provided with mixing bunker that a kind of heat exchanger effectiveness is higher, reduces energy consumption, enhances productivity.
The technical solution of the utility model is achieved in that a kind of heat-exchange device being provided with mixing bunker comprises vapour inlet, condensed water and waste gas outlet and heat exchanger, the many radiating tubes that described heat exchanger comprises hot water and steam pipe and is connected with hot water and steam pipe, there is radiating tube fin this radiating tube outside, described heat exchanger one end is provided with heat exchanger air inlet, the other end is provided with heat exchanger gas outlet, it is characterized in that: described heat exchanger is the heat exchanger of multiple level parallel connection; Closing up after the heat exchanger gas outlet of the plurality of heat exchanger is interconnected is the pipeline that a cross section is narrowed; Be respectively equipped with mixing bunker between described adjacent heat radiation pipe, described mixing bunker can make the air even conjunction of convection current up and down therein by different temperatures after radiating tube.
Preferably, the quantity of described heat exchanger has two at least.
Preferably, the quantity of described radiating tube is at least 8.
Preferably, described radiating tube and radiating tube fin are made up of aluminium or copper product.
The utility model solves the defect existed in background technology, has following beneficial effect:
The heat-exchange device of what the utility model provided be provided with mixing bunker, a complete heat-exchange device is formed by the heat exchanger arranging multiple level parallel connection, add air flow area, in identical amount situation, reduce the flowing velocity of air, extend the time of contact of air and radiating tube, improve heat exchanger effectiveness, reduce energy consumption.Between two-stage radiation pipe, add a mixing bunker, make the even conjunction of cross-ventilation of upper and lower different temperatures in mixing bunker, heat is exchanged fully, rate of heat exchange promotes, and improves production efficiency.

In figure: 1-pressure hot water steam pipe, 2-radiating tube fin, 3-mixing bunker, 4-heat exchanger air inlet, 5-heat exchanger gas outlet, 6-vapour inlet, 7-condensed water and waste gas outlet, 8-radiating tube.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of heat-exchange device being provided with mixing bunker as shown in Figures 2 and 3, comprise vapour inlet 6, condensed water and waste gas outlet 7 and heat exchanger, the many radiating tubes 8 that heat exchanger comprises hot water and steam pipe 1 and is connected with hot water and steam pipe 1, there is radiating tube fin 2 this radiating tube 8 outside, heat exchanger one end is provided with heat exchanger air inlet 4, the other end is provided with heat exchanger gas outlet 5, and heat exchanger is the heat exchanger of two level parallel connections; Closing up after the heat exchanger gas outlet 5 of two heat exchangers is interconnected is the pipeline of a truncated tapered, is conducive to the quick discharge of hot-air like this.Be respectively equipped with mixing bunker 3 between adjacent heat radiation pipe 8, mixing bunker 3 can make the air even conjunction of convection current up and down therein by different temperatures after radiating tube 8.The quantity of radiating tube 8 has 8 at least.Radiating tube 8 and radiating tube fin 2 are made up of aluminium or copper product.
The course of work of the present utility model is: produce pressure steam with pressure boiler, by pipeline, the radiating tube 8 that steam is transported in heat exchanger by pressure hot water steam pipe 1 is carried out thermal energy exchange with air, and produce hot-air from the pipe outlet of heat exchanger gas outlet 5 and discharge, for the production of in oven dry, heating.This is provided with in the heat-exchange device of mixing bunker and is provided with two levels and the heat exchanger connected, two heat converter air-out mouths 5 are interconnected, finally the hot blast by heat exchanger is accumulated one, constitute the heat exchanger of two hot switching paths like this, be just equivalent to increase the dynamic section of heat exchanger hollow air-flow.When equal flow, reduce flow velocity, make the time lengthening of air and heat sink contact, heat exchange is more abundant.For making the air themperature of air duct upper, middle and lower layer balanced, in two adjacent groups radiating tube 8, being respectively equipped with mixing bunker 3, making thermal current carry out heat exchange therein, make the gas flow temperature of levels balanced, improve rate of heat exchange.The condensed water finally produced by radiating tube and waste gas are sent boiler back to by condensed water and waste gas outlet 7 and are carried out heat energy recycle after bottom is collected.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
