Abstract
A steam-water dual purpose boiler includes a boiler drum. A water inlet header and a water outlet header are arranged in the boiler drum, a water inlet is formed on the water inlet header, a water outlet is formed on the water outlet header, a steam-water separating device and a built-in heat exchanger are arranged inside the boiler drum, a steam outlet is formed on the steam-water separating device, and two ends of the built-in heat exchanger are respectively communicated with the water inlet header and the water outlet header. Due to the adoption of the dual purpose boiler, the boiler heating surface always runs under the proper and safe natural circulation condition of the steam boiler; and when the boiler is used as a hot water boiler, the working medium inside the boiler is fully enclosed and has no pollution at all, the heating surfaces is always under the proper and safe natural circulation condition of the steam boiler, and the safety and the reliability of the dual purpose boiler are the things the other hot water boiler do not have.
Description
Technical field
The utility model belongs to a kind of boiler, especially relates to dual purpose steam water boiler.
Background technology
General boiler is to utilize fuel combustion to produce the equipment of steam or hot water; Boiler drum and interior arrangement are used for the interior steam water interface of chamber furnaced and are called steam boiler with the boiler that produces steam; The boiler that boiler drum and interior arrangement are used to separate the hot water of heating is called hot-water boiler; Because the effect of drum interior arrangement is different with function, conventional utility boiler can not provide different pressures steam and hot water simultaneously.But simultaneously frequent or the steam that needs certain pressure of different phase and the hot water of different pressures in real life and the production process, we must adopt the expensive complicated external heat exchanger system of a cover that steam is converted to hot water could satisfy inferior class demand.
General nature circulating hot water boiler is because structure and heat-transfer character cause the inner loop water flow velocity low, and water quality can not guarantee when hot water boiler system and heat network system were straight-through, caused the high heat flux heating surface heat transfer deterioration damage accident often to occur; And forced-circulation hot water boiler flow process complexity, the general layout difficulty, the water collateral resistance is bigger than normal; Therefore improving hot-water boiler heating surface side refrigerant flow rate is the precondition that guarantees hot-water boiler safety.
The utility model content
The purpose of this utility model is to provide the dual purpose steam water boiler of the hot water of a kind of steam that is used for producing simultaneously certain rated pressure and different rated pressures.
In order to achieve the above object by the following technical solutions: comprise boiler drum, be provided with into water collection case and water outlet collection case in the boiler drum, water inlet collection case is provided with water inlet, water outlet collection case is provided with delivery port, boiler drum inside is provided with water separator and built-in heat exchanger, water separator is provided with steam (vapor) outlet, and the built-in heat exchanger two ends are communicated with water inlet collection case and water outlet collection case respectively.
Described water separator is positioned at built-in heat exchanger top, and built-in heat exchanger and water separator are isolated mutually.
Described built-in heat exchanger is positioned at the vapor space or the hydrospace of boiler drum inside.
Described built-in heat exchanger is the heat exchanger of face formula heat exchange.
Advantage of the present utility model is: the built-in heat exchanger that 1, is positioned at the steam of boiler drum inside or hydrospace is compared with the plain cylindrical furnace heating surface has the high coefficient of heat transfer, the built-in heat exchanger heat exchange area is little, volume is easy to built-in for a short time, hot water in the boiler drum in steam and the built-in heat exchanger is independent operating separately, therefore can provide the steam of rated pressure and the hot water of different rated pressures simultaneously, be equivalent to the hot-water boiler synchronous operation of the steam boiler of a platform independent and a platform independent or independent operating separately, realize boiler steam-water dual-purpose function.2, built-in heat exchanger has adopted face formula heat exchanger, its internal hot-water working medium promotes to carry out forced circulation by the outer loop pump, even water quality can not guarantee when boiler hot-water system and heat network system were straight-through, because its internal hot-water flow velocity is far above permissible velocity, heating surface does not possess scaling condition, and its highest heating temperature can be greater than outside saturated-steam temperature, and so the temperature that can bear well below the heating surface metal is the potential safety hazard of having avoided the heat transfer deterioration damage accident to bring fully.3, adopted the boiler of this device, boiler heating surface operates in the good safe condition of steam boiler Natural Circulation all the time; When boiler used as hot-water boiler, boiler internal working medium complete closed did not have contaminating impurity, and heating surface is in the good safe condition of steam oven Natural Circulation, and its security, reliability are that any other hot-water boiler does not possess.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
As Fig. 1, shown in 2, a kind of dual purpose steam water boiler, comprise boiler drum 1, be provided with into water collection case 2 and water outlet collection case 8 in the boiler drum, water inlet collection case 2 is provided with water inlet 3, water outlet collection case 8 is provided with delivery port 7, boiler drum 1 inside is provided with water separator 4 and built-in heat exchanger 6, built-in heat exchanger is the vapor space or the hydrospace that the heat exchanger of face formula heat exchange is positioned at boiler drum inside, water separator 4 is positioned at built-in heat exchanger 6 tops, water separator 4 is isolated mutually with built-in heat exchanger 6, the UNICOM not mutually of working medium separately wherein, water separator 4 is provided with steam (vapor) outlet 5, and built-in heat exchanger 6 two ends are communicated with water inlet collection case 2 and water outlet collection case 8 respectively.
Described water separator is general steam boiler water separator, is positioned at built-in heat exchanger top, and steam (vapor) outlet is UNICOM with it; The steam of steam water interface after initial gross separation enters the top water separator by the built-in heat exchanger outside in the boiler, and the steam of rated pressure is provided through steam (vapor) outlet.
Described built-in heat exchanger is positioned at the steam or the hydrospace of boiler drum inside, adopts the heat exchange of face formula, and water inlet, water inlet collection case are positioned at an end and UNICOM with it, and delivery port, water outlet collection case are positioned at the other end and UNICOM with it; Backwater enters built-in heat exchanger and carries out the heat exchange of face formula with outside saturated vapor or pot water through water inlet, water inlet collection case and forms the hot water, the hot water that need and provide required rated pressure and rated temperature hot water through water outlet collection case, delivery port.
