The utility model is provided with steam trap and adjusting control valve door through the outside cold water pipes position at existing hot air heating apparatus; Condensed water in time will installing is discharged; The phenomenon that effectively anti-locking apparatus gets rusty, corrodes has not only improved heat exchange efficiency, and has guaranteed the safe operation of device.In addition, electronic attemperating unit is set,, adjusts the flow of heating agent steam automatically, under the prerequisite of responsive operation performance not, saved steam energy, avoided waste according to the air outlet temperature at the external steam pipeline position of existing hot air heating apparatus.
Description of drawings
Fig. 1 is the utility model external structure sketch map.
Fig. 2 flies structural representation for the utility model hot air heating apparatus.
Among the figure: 1, control and regulation valve, 2, steam trap, 3, hot air heating apparatus, 4, electronic attemperating unit, 5, bypath valve, 6, blower fan, 7, housing, 8, finned tube, 9, hot-blast outlet.
The specific embodiment
In conjunction with accompanying drawing, the enforcement that provides the utility model is following.
As shown in Figure 1: a kind of mine well head hot air heating apparatus mainly is made up of control and regulation valve 1, steam trap 2, hot air heating apparatus 3, electronic attemperating unit 4 and bypath valve 5; Hot air heating apparatus 3 belongs to the existing Patent equipment of having declared; Comprise blower fan 6, housing 7, finned tube 8, hot-blast outlet 9 (as shown in Figure 2); Housing 7 is made up of framework and backplate, and framework is welded to form by crossbeam, vertical beam and the base of many steel construction welding, and backplate is set around the framework.Hot-blast outlet 9 be housing in the hole that a side is opened, according to circumstances be set to circular or square, rectangle; An other side has the hole, as the cold wind import.Blower fan 6, finned tube 8 are installed in the housing 7, and finned tube 8 is a kind of heat exchanger tubes, are in order to improve heat exchange efficiency, usually on the surface of heat exchanger tube through with fin, increase the external surface area (or internal surface area) of heat exchanger thus reach the purpose that improves heat exchange efficiency.Steam passes through from finned tube, and outdoor cold air is outside through promoting temperature later from finned tube through blower fan.
Finned tube 8 one ends link to each other with device external steam pipeline, and the other end links to each other with the outside cold water pipes of device, and electronic attemperating unit 4 and bypath valve 5 are installed on the jet chimney, and steam trap 2 and by-pass valve control 1 are installed on the cold water pipes.
The cold water pipes of hot air heating apparatus 3 is provided with steam trap 2 and adjusting control valve door 1; Steam trap and adjusting control valve door belong to valve type; Be installed on the pipeline; Concrete mounting means is to pick out a segment pipe in the finned tube lower end of hot air heating apparatus 3, and steam trap and adjusting control valve door are connected on this segment pipe through flange.What steam trap 2 adopted is known products, is an automatic valve, plays the effect of draining resistance vapour; Operation principle is when steam becomes condensate liquid, and temperature also decreases, and the heated element in the steam trap is shunk; The needle valve door opened carry out condensate drain, in this process, along with flowing of condensate liquid; Inevitably steam is taken out of, but the heated element that steam can heat in the steam trap makes it expansion, with valve closing.The basic role of Automatic steam trap Trap is that the condensate in the vapour system, air and carbon dioxide are discharged as early as possible; Prevent automatically to greatest extent that simultaneously the leakage (1) of steam from can get rid of the condensate of generation rapidly.(2) prevent steam leakage (3) deaeration and other non-condensable gas), the assurance device safe operation.On the jet chimney of hot air heating apparatus 3, also be connected with electronic attemperating unit 4 and bypath valve 5; Electronic attemperating unit and adjusting control valve door also belong to valve type; Be installed on the pipeline; Concrete mounting means is that the finned tube at hot air heating apparatus 3 advances steam or the high-temperature water termination goes out a segment pipe, electronic attemperating unit and regulate control and be connected on this segment pipe through flange.What electronic attemperating unit 4 adopted is conventional product.
During use, outdoor heating agent passes through pipeline and gets in the finned tube 8, and outdoor cold wind gets in the housings 7 and the heating agent generation heat exchanges of flowing in the finned tube 8 through blower fan 6, and heated air gets into the well head air channels through hot-blast outlet 9.The temperature sensor that is arranged on hot-blast outlet 9 is exported the electronic attemperating unit 4 of signal controlling through induction and judgement to leaving air temp, adjusts the flow of steam automatically.When electronic attemperating unit 4 goes wrong, can close electronic attemperating unit 4, open bypath valve 5, do not influence the normal operation of device.Steam trap 2 and the adjusting control valve door 1 that is arranged on hot-blast outlet 9 positions be the condensed water in the discharger in time.
