Abstract

The utility model relates to a device used for replenishing water a boiler by a water tank of a solar closed-loop residual heat water heater, which belongs to the technical field of water replenishment. Cold water which is already softened is injected into a solar water heater to be heated, and the water is injected in a cubic heat insulating water storage tank made of steel plates by a water pipe. The utility model is connected with a fire pipe residual heat water heater which is on a boiler flue and is made of steel plates and fire pipes, after the temperature of the water is raised after the water is heated by utilizing the residual heat of the flue, the water flows back to the storage water tank by an overflow water pipe arranged on the upper part of the residual heat water heater, the temperature of the water is raised after the water is heated, and a closed-loop heat circulation system can be formed; the temperature of emergency water is raised after emergency water is repeatedly heated, and the water with the temperature of 45DEG. Cto 90DEG. C can be replenished to a boiler by a water replenishing pump of the boiler at any time. Device utilizes natural energy resources and residual heat energy resources to heat water, and water enters the boiler after heated; thus, the combustion time of the boiler is shortened, a large quantity of energy consumption is decreased, and the problem that solar energy can not be normally used under the condition of no sunshine, and the production efficiency in the process of the operation of the boiler is increased.

Description

The closed circuit heat retrieving apparatus storage tank of solar energy boiler of feeding water replanishing device

Technical field

The utility model relates to the boiler replenishing water field.

Background technology

Existing boiler replenishing water system is after running water softening is handled, directly to inject boiler.The moisturizing temperature is relevant according to area, season, weather, and general water temperature is all between 7 ℃-13 ℃.After cold water enters boiler, use fuel promptly: burning such as coal, oil, coal gas or natural gas is heated, and water temperature is risen to steam more than 100 ℃ use for producing.And this combustion process, boiler operatiopn must divide about clock time by 20-40 under the normal condition, and the process of this burning operation is consuming a large amount of energy, a large amount of energy cost in producing in occupation of enterprise.Also in environment, discharging multiple pernicious gases such as a large amount of carbon monoxide, sulfur dioxide, nitrogen oxide and flue dust simultaneously.

Original boiler for producing factory be furnished with old-fashioned economizer for energy-conservation, but performance is not clearly.And easily collection is dirty, and easy to clean is not big to also existing resistance in the boiler use, problems such as blower fan power consumption height.

Utilize heat pump techniques in recent years in addition, use the temperature difference of deep phreatic water and surface water to exchange heat for, and the problem that this technology exists in real world applications is: at first will seek underground thermal source, bore the deep-well of two mouthfuls of dark hundreds of rice even last km to boiler replenishing water.Not only want groundwater abstraction also will recharge underground water in the utilization and operation, the cost cost is bigger.The pollution that also unavoidable underground water is in use destroyed and can't administer.But also fibrous root uses under the supervision of water resources management department, so can not popularize according to regional condition and enterprise's ability to bear.

Also have " epoch are praised magnificent burning boiler modification scheme " of Tsing-Hua University's design to use in boiler room, the Capital Airport.The system keeps track that uses a computer is monitored the design of equal permanent heat supply.System complex, costly, energy-conservationly have only 9%, considerable fund input, the huge and most of enterprises of complication system all are difficult to accept.

And current existing boiler design comprises that fire coal, fuel oil, gas fired-boiler design are closely perfect, and to go to transform boiler more unrealistic for energy-conservation.

Summary of the invention

The utility model is the energy-conservation concurrent heating water apparatus system of installing outside boiler body of a cover.Make boiler in burning is used, reach the positive effect of saving energy 30%-50%.Cardinal principle is: utilize existing solar energy to catchment boiler demineralized water that heat treated crosses, it is standby to flow into storage water tank heat insulation automatically by natural drop.After being communicated with the boiler flue heat retrieving apparatus, form closed cycle with storage tank, once more after the heating and heat preservation, the hot water that replenishes 45 ℃-90 ℃ in order to boiler at any time enters boiler.Shorten the process that the boiler combustion quickening is steamed, reach the practical function of energy savings, raising boiler efficiency, minimizing disposal of pollutants.

Adopted heliotechnics to carry out the cold water heating during the design of this device is used, use be natural energy resources.Heated hot water flows into storage water tank heat insulation, employing be the drop technology.Water in the storage tank flows into heat retrieving apparatus automatically, utilizes the heat of boiler flue to heat once more, employing be the UTILIZATION OF VESIDUAL HEAT IN technology.It is the thermal expansion overflow technology of utilizing that adds that the hot water of heat retrieving apparatus flows into storage tank once more.Therefore in the operation use, the power source that need not add any paid utilization again drives.Essentially no operating cost input, but use without compensation.This is characteristics of the present utility model and advantage.

Description of drawings

Fig. 1 is that the utility model is at the schematic diagram that uses in installing;

Fig. 2 is the application scheme of installation of the utility model in water boiler or bath boiler.

1 solar energy, 2 storage tanks, 3 heat retrieving apparatus, 4 sterilizing filters among the figure.

The specific embodiment

Be described in detail the utility model specific embodiment below in conjunction with accompanying drawing:

As shown in Figure 1, inject solar energy 1, flow into storage tank 2 insulations automatically through open check valve after the solar energy heating and store, flow into the heat retrieving apparatus 3 on the boiler flue, overflow back storage tank behind the heat temperature raising once more, boiler of feeding moisturizing at any time through the softening cold water of handling.

As shown in Figure 2,1 heating overflows back storage tank 2 after flowing into storage tank 2 process boiler afterheat device heat temperature raisings to running water through solar energy, and hot water enters boiler for drinking or bathing behind sterilizing filter 4.

In the utility model specific implementation process, solar energy need only be concentrated to be connected and installed.Just can move use after storage tank and water heater using waste heat be connected by the pipeline of requirement among the figure.Closed cycle heating system in the design has solved because of the Changes in weather short time is unglazed shines under the situation the out of use realistic problem of solar energy.
