Abstract
The invention discloses a single-station annular heat supply pipe network which comprises a vacuum water heating boiler and a pressurizing circulating device matched with the vacuum water heating boiler. A water outlet of the vacuum water heating boiler is connected with one end of a water outlet pipe of a heat supply pipe a, and the other rend of the water outlet pipe of the heat supply pipe a is plugged. A water return port of the pressurizing circulating device is connected with one end of a water return pipe of a heat supply pipe b, and the other end of the water return pipe of the heat supply pipe b is plugged. According to the single-station annular heat supply pipe network, the heat supply pipe network is designed to be annular, the tail end of the water outlet pipe and the tail end of the water return pipe are plugged, and accordingly the situation that heat supply media of a conventional heat supply system return while moving forwards is avoided, and the heat supply amount along the pipes is basically uniform. Besides, the pipe network is ingenious in structure, low in cost and easy to popularize, and circulating use of water resources is achieved.
Description
Technical field
The invention belongs to boiler heat supplying equipment technical field, relate to a kind of single station loop type heating network.
Background technology
Heating network refers to by concentrated supply of heating in the city thermal source to carrying for hot-zone and distributing the pipeline system of heating medium.In city, adopt boiler to be supply hot-zone central heating to be heating form the most general in current heating network.It is provide the outlet conduit of hot water for hot-zone and return the water return pipeline of cold water with heating network.This heat-supplying mode Problems existing is: due to heat supply offset thermal source distance not etc., the confession hot-zone that distance supplying heat source can be caused near is all right because heating medium distributes more heating effects, far away the declining along with the increase of length of pipeline for hot-zone heating medium of distance supplying heat source, heating effect obviously reduces, this walks while return in the duct, reduce flow velocity and flow gradually, cause apart from the near confession hot-zone heat of thermal source, what distance thermal source was far away supplies hot-zone cool, pipe network temperature far away is lower, until pipe end does not have temperature.
Summary of the invention
The object of the present invention is to provide a kind of single station loop type heating network, the heating medium solved in existing heating network is walked while return, and makes the problem that flow velocity and flow reduce gradually.
The technical solution adopted in the present invention is: a kind of single station loop type heating network, the pressurized circulation equipment comprising vacuum hot water boiler and mate with it, the delivery port of vacuum hot water boiler is connected with one end of heating tube a outlet pipe, the other end shutoff of heating tube a outlet pipe, the water return outlet of pressurized circulation equipment is connected with one end of heating tube b return pipe, the other end shutoff of heating tube b return pipe.
Feature of the present invention is also:
Pressurized circulation equipment is made up of two or more force (forcing) pumps and stop valve.
The internal diameter of heating tube a outlet pipe evenly reduces from the one end be connected with vacuum hot water boiler to shutoff end.
The internal diameter of heating tube b return pipe evenly increases from the one end with pressurized circulation equipment connection to shutoff end.
The invention has the beneficial effects as follows: the present invention is a kind of single station loop type heating network, heating network is designed to annular, no matter how long pipeline has, and its heat exchange loop number of times is the same, and temperature is balanced all the time, solve conventional tube selvage to walk limit and return, reduce flow velocity, flow gradually, cause thermal source hot nearby, cool at a distance, pipe network temperature far away is lower, until the marantic drawback of pipe end.Loop network system is without any need for control, and unimpeded circular flow, eliminate resistance and the flow of control valve and control valve, systemic circulation is smooth and easy without hindrance, energy-efficient.Pressure differential before and after in the change of outlet pipe and return pipe internal diameter reduces and manages, assignment of traffic rationally, evenly, so for thermal balance, both decreased and much controlled to adjust valve, and do not wasted thermal source again, had reached little, the high object of producing effects of investment.In addition, this apparatus structure is exquisite, and cost is low, achieves recycling water resource, is easy to promote.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of single station of the present invention loop type heating network.
In figure, 1. vacuum hot water boiler, 2. pressurized circulation equipment, 3. heating tube a, 4. heating tube b.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
A kind of single station loop type heating network, as shown in Figure 1.The pressurized circulation equipment 2 comprising vacuum hot water boiler 1 and mate with it, the delivery port of vacuum hot water boiler 1 is connected with one end of heating tube a3 outlet pipe, the other end shutoff of heating tube a3 outlet pipe, the water return outlet of pressurized circulation equipment 2 is connected with one end of heating tube b4 return pipe, the other end shutoff of heating tube b4 return pipe, pressurized circulation equipment 2 is made up of multiple force (forcing) pump and stop valve, the internal diameter of heating tube a3 outlet pipe evenly reduces from the one end be connected with vacuum hot water boiler 1 to shutoff end, the internal diameter of heating tube b4 return pipe evenly increases from the one end be connected with pressurized circulation equipment 2 to shutoff end.
During use, the water heated through vacuum hot water boiler 1 is along the outlet pipe of heating tube a3 to carrying out heat supply for hot-zone, and the water return outlet and then flow in vacuum hot water boiler 1 flowing into pressurized circulation equipment 2 along the return pipe of heating tube b4 afterwards recycles.
In heat supplying process, if the water shortage in heating network, the water supplement port by pressurized circulation equipment 2 adds water.
The present invention is a kind of single station loop type heating network, heating network is designed to annular, no matter how long pipeline has, and its heat exchange loop number of times is the same, and temperature is balanced all the time, solve conventional tube selvage to walk limit and return, reduce flow velocity, flow gradually, cause thermal source hot nearby, cool at a distance, pipe network temperature far away is lower, until the marantic drawback of pipe end.Loop network system is without any need for control, and unimpeded circular flow, eliminate resistance and the flow of control valve and control valve, systemic circulation is smooth and easy without hindrance, energy-efficient.Pressure differential before and after in the change of outlet pipe and return pipe internal diameter reduces and manages, assignment of traffic rationally, evenly, so for thermal balance, both decreased and much controlled to adjust valve, and do not wasted thermal source again, had reached little, the high object of producing effects of investment.In addition, this apparatus structure is exquisite, and cost is low, achieves recycling water resource, is easy to promote.
