Abstract
A whirl water mixer belongs to the engineering technical field of boiler heating heat energy, which is provided with a casing tube with water mixer cavity. The water inlet end of the casing tube is welded with the boiler heat supply pipeline flange and the water outlet end is welded with the heating heat supply pipeline flange, the heating water return flange is welded on the side wall of the casing tube with water mixer cavity and is communicated with the inner portion of the casing tube with water mixer cavity. A spiral water conduit is disposed in the inner of the casing tube with water mixer cavity, the water inlet end of the spiral water conduit and the water inlet end of the casing tube with water mixer cavity forms to a combination, and the other end penetrates into the cavity of the casing tube with water mixer cavity to weld a strip- shaped flight in the spiral water conduit. Application of the utility model is capable of realizing continuous operation of energy conserving of hot-water boiler 'small flow and high temperature' to overcome the defects of boiler technical parameter can not be achieved and fuel is wasted because of time-share run of 'high volume and low temperature' in the past, and realizing employing the heating system 'high volume and moderate temperature' to supply heating continuously to overcome the shortcoming of the time-share heating in the past.
Description
Technical field
The utility model belongs to the Thermal Power Engineering technical field, relates to the corollary equipment of heating boiler, is specifically related to a kind of heating boiler heat supplying pipeline eddy flow water-water jet.
Background technology
In the current domestic city central heating net, how with fire coal, fuel oil, gas fired-boiler for being supplying heat source, to heat supply network housing-group supply steam, hot water circuit heating.When stoker workman operates, just according to weather forecast situation decision heating duration.In one day 24 hours, control boiler combustion at times to the heat supply of heating housing-group.The shortcoming of this method of operating is, the one, and temperature does not reach metastable level of comfort in the heating user 24 hours, i.e. indoor temperature height during boiler operatiopn heat supply, indoor temperature descends during shutdown of boiler, and is sometimes hot and sometimes cold; The 2nd, because heating boiler burns at times, after each blowing out, fire box temperature descends, and when playing stove once more, need a period of time to improve fire box temperature, just can reach the optimal economic value of boiler design parameter, each stove fuel can not fully burn and cause waste, and destroys air ambient.Cause the principal element of this drawback to be not develop the desirable corollary equipment of boiler heat supplying pipeline and water return pipeline.
In recent years, country pays much attention to the concentrated supply of heating in the city quality, stresses the energy-saving effect of boiler fired coal, fuel oil, combustion gas and heating user's heating quality in particular, advocates the technological development of " boiler energy-saving, heat supply controlled " and the development work of new product energetically.
Summary of the invention
At the problem that above-mentioned present heating boiler exists, the utility model provides a kind of eddy flow water-water jet, reaches boiler water supply and water return secondary heat exchange, to the purpose of heating user continuous heat supply.
Eddy flow water-water jet of the present utility model, have a mixed water cavity sleeve pipe, sleeve pipe water inlet end welding boiler heat supplying pipe flange, the other end are water outlet end welding heating pipe flange, welding heating backwater divides pipe flange on mixed water cavity sleeve pipe sidewall, is communicated with mixed water cavity inside pipe casing.In mixed water cavity sleeve pipe the spiral aqueduct is set, spiral aqueduct water inlet end and mixed water cavity sleeve pipe water inlet form one, and the other end deeply mixes in the water cavity casing cavity.The spiral aqueduct has the undergauge structure, and promptly the water inlet internal diameter is greater than the delivery port internal diameter.At the flight of spiral aqueduct inwall welding bar shaped, quantity is 5,6 or 8, and by circumferential even distribution, each flight axially becomes 30～45 with the spiral aqueduct.
During use, eddy flow water-water jet of the present utility model is installed in the junction of hot-water boiler heat supply pipeline and heating pipe, and of heating water return pipeline is connected to the heating backwater divides on the pipe flange.
High-temperature water from hot-water boiler enters the spiral aqueduct, under the effect of spiral aqueduct undergauge and spiral inner wall sheet, form the spiral spray current, these current and the part water at low temperature of being in charge of from the heating backwater are mixed in mixing water cavity and are carried out the secondary heat exchange, warm water in the formation flows into the heating pipe network through mixing water cavity sleeve pipe delivery port.Another part water at low temperature from the heating pipe network is regulated the valve regulation flow by Based Intelligent Control, flows to the boiler blow-down water trunk line.
The utility model manufacturing process and product is divided into two kinds, mix water cavity sleeve pipe water inlet caliber Φ 100～300mm's, the processing of employing precision casting process, mix water cavity sleeve pipe water inlet caliber Φ 300～1000mm's, adopt boiler plate hot pressing, cold coiling, welding procedure processing, end face of flange turning, boring.
The utility model product and the electronic monitoring work system is supporting installs and uses, after constituting the work system of the energy-conservation Based Intelligent Control of concentrated supply of heating in the city, can realize the energy-conservation continuous operation of hot-water boiler " low discharge high temperature ", overcome the drawback that " big flow low temperature " operation does not at times in the past reach the boiler technology parameter, wastes fuel; Can realize heating system " temperature in the big flow " continuous heat supply, overcome the sometimes hot and sometimes cold drawback of heating terminal that in the past heats at times.
Use the utility model product, can transform original heating system, also can direct newly-built heating system, initial designs is installed and used.The utility model product manufacture is simple, with low cost, simple installation, and operational effect is reliable and stable, can save 20～30% fuel on the basis of former power consumption.In the winter heating area extensive use of northern half China.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that Figure 1A-A is to view.
Among the figure: 1 boiler heat supplying pipe flange, 2 mix the water cavity sleeve pipe, 3 heating pipe flanges, 4 heating backwater divide pipe flange, 5 flights, 6 spiral aqueducts.
The specific embodiment
As shown in Figure 1 and Figure 2, eddy flow water-water jet of the present utility model, has a mixed water cavity sleeve pipe 2, sleeve pipe water inlet end welding boiler heat supplying pipe flange 1, the other end is a water outlet end welding heating pipe flange 3, welding heating backwater divides pipe flange 4 on mixed water cavity sleeve pipe 2 sidewalls, with mixed water cavity sleeve pipe 2 internal communication.In mixed water cavity sleeve pipe 2 spiral aqueduct 6 is set, its water inlet end and mixed water cavity sleeve pipe water inlet form one, and the other end deeply mixes in the water cavity casing cavity.Spiral aqueduct 6 has the undergauge structure, and promptly the water inlet internal diameter is greater than the delivery port internal diameter.At the flight 5 of spiral aqueduct inwall welding bar shaped, quantity is 5,6 or 8, and by circumferential even distribution, each flight and spiral aqueduct axially become 30,35,40 or 45.
