Abstract

The utility model relates to a device allowing a solar energy centralized heating engineering scale to be adjusted. The device comprises a plurality of sets of solar heat collection modules and a water storage tank, wherein water outlet pipes of the solar heat collection modules are connected with the water storage tank, a water inlet pipe of each set of solar heat collection module is provided with a first valve, the water outlet pipe of each set of solar heat collection module is provided with a second valve, and water suction pumps are arranged between the first valves of the water inlet pipes of the solar heat collection modules and the water storage tank. The device allowing the solar energy centralized heating engineering scale to be adjusted has the advantages that by adjusting the number of the solar heat collection modules, amount or temperature of generated hot water is controlled, and heat generation is adaptive to heat utilization, thus the situation that the device and pipeline fittings are damaged because water temperature of a system is overhigh is avoided, and a whole solar energy heat collection system device is protected.

Description

A kind of device of capable of regulating central solar heating project scale
Technical field
The utility model belongs to the solar thermal utilization aspect, is exactly by changing the heat production scale of solar thermal collection system heat collector, making heat production with mutually suitable by heat, thereby avoid the too high protection of system water temperature solar energy heat collector.
background technology
In solar thermal collection system, be that the warm washing water by building measures to determine its heat collector scale.Generally, the heat collector quantity come into operation is certain.Solar thermal collection system is to be operated in the state that absorbs solar energy always, and can improve along with the increase of intensity of solar radiation the heat production function.But, along with the rising of atmospheric temperature, the water temperature that the people accepts requires but more and more lower., when otherwise atmospheric temperature is lower, people's water temperature used requires higher; The solar energy system design generally designs the area of solar thermal collector season according to spring and summer, when summer, will cause solar heat collector to supply heat much larger than asking or in the consumption state of not loading temporarily, with not mating of thermic load and solar-heating, making solar thermal collector is the air drying state by vexed solarization state-transition.
Air drying is excessively of a specified duration, in solar thermal collector, can produce a large amount of steam.If steam is discharged not in time, or discharge when not smooth, can make steam pressure in solar thermal collector raise, when pressure surpasses solar thermal collector and bears pressure, just thermal-collecting tube can break, cause " bombing ".This can cause the operating efficiency of solar thermal collector greatly to descend, and makes solar energy system can not give full play to due energy-saving effect.And " once bombing ", whole solar thermal collection system will quit work, and needs a large amount of human and material resources to be keeped in repair, and causes very large energy waste and economic loss, has both damaged equipment, brings again huge potential safety hazard.
This applicable new patent is exactly; adjust the heat collector quantity that drops into heat production, thereby control the quantity that produces hot water, make heat production with mutually suitable by heat; pent collector module can be avoided bombing by shifting to an earlier date emptying and exhaust measure, thereby protects whole solar thermal collection system.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, drops into the solar energy heat collecting module quantity of heat production by adjustment withthe variation of solar thermal collector flow, thus quantity or the temperature that produces hot water controlled, make heat production with mutually suitable by heat, thereby avoid the heat collector air drying, protect whole solar energy heat collector.
The technical scheme of technical solution problem is, a kind of central solar heating device of capable of regulating scale, comprise many group solar energy heat collecting modules, storage tank, the solar energy heat collecting module outlet pipe is connected with storage tank, each solar energy heat collecting module water inlet pipe place is provided with the first valve, the outlet pipe place is provided with the second valve, between the second valve of solar energy heat collecting module outlet pipe and described storage tank, is provided with suction pump.
All right, also be provided with temperature inductor, level switch on storage tank.
All right, storage tank is communicated with filling pipe, and filling pipe is provided with the moisturizing magnetic valve.
All right, temperature inductor, level switch are connected with described controller respectively, by Artificial Control the first valve, the second valve duty, control solar energy heat collecting module inflow and water yield.
All right, temperature inductor, level switch are connected with described controller respectively, and controller, by controlling the duty of moisturizing magnetic valve, is controlled the rate of water make-up of storage tank.
All right, temperature sensor, constant temperature moisturizing magnetic valve are connected with described controller respectively, and controller, by controlling constant temperature moisturizing electromagnetic valve work state, is controlled the inflow of solar energy heat collecting module.
The utility model has the advantage of, use above structure, by controlling the duty of the first valve, realize controlling the solar energy heat collecting module inflow, the second valve duty is controlled in earthing, realizes controlling the solar energy heat collecting module water yield, in the time of need to allowing solar energy heat collecting module quit work, first close the first valve and the second valve, remove one, this module top vacuum tube, then extract one of this module bottom vacuum tube out.Allow the vacuum pore that water in module is removed from bottom discharge, the vacuum pore that water that can't be emptying by the bottom vacuum tube in vacuum tube is removed from top by the water vapour produced is discharged, and can realize adjusting the function of the solar energy heat collecting module quantity that drops into heat production.
Excess Temperature in storage tank, and water level is controlled moisturizing electromagnetic valve work state by artificial or controller when low, control filling pipe to rate of water make-up in storage tank, realizes the control to the storage tank water temperature.
When water storage the temperature inside the box is too low, and water level is when higher, control the first valve, the second valve duty by artificial or controller, open the first valve, the second valve and suction pump, water in storage tank is reentered in solar energy heat collecting module from the solar energy heat collecting module water inlet pipe, by suction pump, the hot water of solar energy heat collecting module is pressed into to storage tank by outlet pipe again after heating, realizes the control to the storage tank water temperature.
