Abstract
The utility model discloses a heat-storage water tank having heat-storage materials and mainly comprises a tank body, a liquid-level gauge, a thermal resistance and a water-recharging valve, which is characterized in that a heat-storage pipe unit having the heat-storage materials is arranged at the middle-upper parts and the heat district of the tank body of the heat-storage water tank; a plurality of heat-storage pipes in the heat-storage pipe unit are horizontally arranged and are spaced to each other. The arrangement of the heat-storage pipe unit is vertical to the water flow direction, thus being convenient for the rapid heat exchanging between the water and the heat-storage pipe unit. The utility model has the advantages that the heat-storage quantity is increased, the volume of the water tank is reduced, the dead corner of the water tank is reduced and the utilization rate of the water tank is enhanced. Adopting the water tank, the water temperature is uniformly distributed, which can improve the layered problems of the water in the water tank, can improve the heat-supply quality and can provide the hot water source at 90 DEG C for a long time. When the water flows from the cool side to the hot side of the water tank, the heat is continuously passed from the heat-storage pipe to the cool-side water, thereby enhancing the temperature of the output hot water. The heat-supply quality of the utility model is equal to that of the normal furnace for 70 percent time.
Description
Technical field
The utility model relates to the hot water storage tank in a kind of heating plant, particularly heating plant.
Technical field
Heat accumulating type electrical heating unit be utilize in the electrical network night dip electricity with water heating and thermal isolation and heat storage in hot water storage tank, for daytime hot-water supply, bathing and heating.It is the environmentally friendly machine of current alternative coal fired boiler.Its advantage is a cleanliness without any pollution, and the method for operation is flexible, utilizes low ebb electricity, operating cost low; compact conformation is easy for installation; volume is little, area occupied is little, and electromechanical integration, operation automation be operations staff, saving labour cost specially, multiple protective, safe and reliable to operation.Hot water storage tank is one of equipment important in the heat accumulating type electrical heating machine set system.The hot water storage tank heat storage medium is a water at present, because the sensible heat of water is less, so the hot water storage tank of large-scale electrical heating unit is corresponding bigger.Therefore there are the following problems in the concrete application of hot water storage tank:
1, the water tank volume is big, the cost height, and floor space is big;
2, the water tank volume is big more, and the dead band is big more, and heat loss is big more;
3, water tank temperature field is inhomogeneous.
4, owing to hot water storage tank heating in 24 hours, passing in time, the heating quality is worse and worse.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of hot water storage tank that installs heat-storing material additional, to guarantee passing in time, improves the heating quality.
For achieving the above object, technical solution of the present utility model provides a kind of hot water storage tank that installs heat-storing material additional, mainly comprise casing 1, liquid level gauge 6, thermal resistance 7, water compensating valve 8, it is characterized in that being provided with the heat accumulation pipe group 2 that installs heat-storing material additional in the middle and upper part and the hot-zone of hot water storage tank casing 1, heat accumulation pipe in the described heat accumulation pipe group 2 is horizontal, heat accumulation pipe all has distance at interval each other, the setting of heat accumulation pipe group 2 is vertical with water (flow) direction, so that water and the heat exchange fast of heat accumulation pipe group.
Effect of the present utility model is to have increased amount of stored heat, the corresponding minimizing of water tank volume, and the utilization rate of water tank has been improved in the dead band of having reduced water tank simultaneously.This water tank makes distribution of water temperature even, improves water tank water body lamination problem.Improved the heating quality, 90 ℃ thermal water source can be provided for a long time.Heat accumulation pipe is constantly passed to cold side water to heat during water tank cold side water thermotropism side flow, has improved heat like this and has gone out water temperature.70% time is identical with normal boiler heating quality.
Description of drawings
Fig. 1 is the hot water storage tank structure diagram.
The specific embodiment
Reaching embodiment is in conjunction with the accompanying drawings described in detail the utility model.
As shown in Figure 1, the hot water storage tank that installs heat-storing material additional mainly comprises casing 1, liquid level gauge 6, thermal resistance 7, water compensating valve 8, the hot water storage tank that installs heat-storing material additional is to have adopted a kind of heat-storing material in heat accumulation pipe group 2, this heat-storing material is sealed in makes heat accumulation pipe in the seamless steel pipe.Heat-storing material is a kind of phase change composite material.When being elevated to 89 ℃, temperature produces phase transformation.Become liquid by solid.In phase transition process, absorb a large amount of heats.In the heating process along with water tank in the decline of water temperature, be lower than 89 ℃ after phase-change material again the latent heat that phase transformation absorbed is discharged, water is heated once more.Phase-change material becomes solid by liquid again.Its basic parameter: 1, the phase transformation fusing point is 90 ℃, and 2, setting temperature 86-89 ℃, 3, dissolve latent heat 52-55Kcal/kg, 4, density of solid 1.65kg/L.Its temperature lowering curve such as figure below:
The amount of stored heat that can measure every 1KG phase-change material in 30 ℃ of temperature ranges of 95-65 ℃ from temperature lowering curve is 3 times of heat of water.
The technology of this hot water storage tank is achieved in that above-mentioned heat-storing material is sealed in makes heat accumulation pipe in the seamless steel pipe, the heat accumulation pipe group 2 of one group of group is positioned in the hot water storage tank, and heat accumulation pipe group 2 is horizontally, and is vertical with water (flow) direction.Between the horizontal heat accumulation pipe, certain distance is all arranged up and down at interval,, improve the utilization rate of water tank so that water and heat accumulation pipe group are carried out heat exchange as early as possible.Because distribution of water temperature is inhomogeneous in the water tank, so the heat accumulation pipe group is positioned over the middle and upper part and the hot-zone of water tank,, fast latent heat is discharged so that heat-storing material can carry out phase transformation under phase transition temperature, improve heat exchanger effectiveness.Install deflector 3 in water tank additional, the position between the adjacent weather board makes water by certain flow direction motion, thereby reduces the dead band for staggering up and down.Be provided with heat in the heating import department of hot water storage tank and advance water distributor 5, be provided with the cold mozzle 4 that goes out at hot water storage tank cooling water outlet place, the hot water that adds of this water tank heating import department is evenly distributed in the water tank, water distributor is established in outlet in time derives many places cold water.The hot water storage tank that installs heat-storing material additional can be widely used in the heating unit, is the environmentally friendly machine of a kind of performance high-quality, energy savings.
