Abstract
A free scaling phase-change boiler whose outside is provided with a heat exchanger relates to the improvement of a boiler structure. The utility model provides a free scaling phase-change boiler whose outside is provided with a heat exchanger which can avoid the scaling of the heat exchanger, and can be detached and maintained conveniently. The utility model comprises a boiler whose structural key points are that the boiler is respectively connected with the heat exchanger on the upper portion of the boiler and a casing through an air duct and a condensed water pipe, the upper portion and the lower portion of the heat exchanger are respectively provided with an air discharge valve, a venting valve, a safety valve and a water discharging valve, and the two sides of the heat exchanger are respectively provided with a water inlet and a water outlet.
Description
Technical field:
The utility model relates to the improvement of boiler structure.
Background technology:
There is the problem that is difficult to overcome in the employed built-in heat exchanger of existing boiler, and mainly is heat exchanger scaling problem.Incrustation scale worsens the heat-transfer behavior of heat exchanger, and the heat exchanger heat transfer coefficient is descended, and pressure raises boiler because the heat transfer coefficient of heat exchanger descends, and causes the pressure of boiler to exceed design parameter and can not use.Especially for the boiler of heat supply, heat exchanger and heat supply network in the boiler are systems; Water capacity is big in the heat supply network, is difficult to guarantee by water treatment the quality of water, and impurity forms incrustation scale by depositing and separating out at the heat exchanger inwall in the water in the heat exchanger, has seriously influenced heating efficiency; In addition, heat exchanger also is difficult to the dismounting maintenance.
The utility model content:
The utility model is exactly at the problems referred to above, and provide a kind of and can avoid fouling of heat exchangers, and the Phase transformation boiler of dismounting non-scaling external heat exchanger easy to maintenance.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises boiler, its structural feature boiler links to each other with the shell of the heat exchanger of boiler top by wireway, condensate pipe respectively, the top of heat exchanger, below are respectively arranged with air bleeding valve, exhaust-valve, safety valve, discharging valve, and the both sides of heat exchanger are respectively arranged with water inlet, delivery port.
The beneficial effects of the utility model:
1, non-scaling:
Because heat exchanger of the present utility model is arranged on the outer top of boiler, make heat exchanger not be subjected to the constraint of boiler, especially can adapt to the big heat supply network of water capacity and use; Strengthen the number of the conduit of heat exchanger, make the water velocity in the conduit that water impurity is not precipitated, thereby realized the purpose of heat exchanger non-scaling, the service life of having improved heat exchanger;
2, dismounting is easy to maintenance:
Because heat exchanger of the present utility model is arranged on outside the boiler, can under the situation that does not influence boiler, carry out the dismounting maintenance, for using, the user provides convenience.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment:
The utility model comprises boiler 13, boiler 13 links to each other with the shell 1 of the heat exchanger 3 of boiler 13 tops by wireway 12, condensate pipe 14 respectively, the top of heat exchanger 3, below are respectively arranged with air bleeding valve 7, exhaust-valve 5, safety valve 6, discharging valve 8, and the both sides of heat exchanger 3 are respectively arranged with water inlet 10, delivery port 11.
Water level in the boiler 13 monitors by water level meter 9, pressure in the heat exchanger 3 monitors by Pressure gauge 4, incoagulable gas in the heat exchanger 3 emits by exhaust-valve 5, and the gas that the water in the heat exchanger 3 produces in heat transfer process emits by air bleeding valve 7.Water in the heat exchanger 3 can bleed off by discharging valve 8.
Side at the shell 1 of heat exchanger 3 can be provided with manhole 2; The maintenance personal can overhaul by shell 1 inside that manhole 2 enters into heat exchanger 3.
The shell 1 of heat exchanger 3 is welded on the boiler 13 by wireway 12 and condensate pipe 14, and heat exchanger 3 is placed on the support 15 in heat exchanger 3 shells 1.Water in the heat supply network enters in the heat exchanger 3 by water inlet 10, enters into heat supply network by delivery port 11 again after the absorption heat rising temperature, finishes heat exchange.Steam in the boiler 13 enter in the heat exchanger 3 by a plurality of wireways 12, and condensation heat transfer is passed to water in the heat exchanger 3 to heat, and water temperature is raise.Become condensate water after the steam heat release, get back in the boiler 13 by condensate pipe 14.
Claims (1)
1, the Phase transformation boiler of non-scaling external heat exchanger, comprise boiler (13), it is characterized in that boiler (13) links to each other by the shell (1) of the heat exchanger (3) above wireway (12), the same boiler of condensate pipe (14) (13) respectively, top, the below of heat exchanger (3) is respectively arranged with air bleeding valve (7), exhaust-valve (5), safety valve (6), discharging valve (8), and the both sides of heat exchanger (3) are respectively arranged with water inlet (10), delivery port (11).
