Abstract
The large-scale heat accumulation water pitcher uses the unit type water-distributing device. The phenomenon of uneven water inlet and outlet quantity in the water tank is easy to occur in the water inlet and outlet process of the water tank, and the inclined temperature layer at the junction of cold water and hot water is extremely easy to be damaged due to the disturbance of the water inlet and outlet, so that the normal use of the system is seriously influenced. The invention comprises the following components: the water distributor comprises a unit-type water distributor (3), a plurality of water distribution branch pipes (2) and a water distribution main pipe (1), wherein a plurality of water inlets and water outlets are uniformly formed in the unit-type water distributor and are radially arranged, the water distribution branch pipes are radially arranged and are communicated with the water distribution main pipe, and each water distribution branch pipe is communicated with the water inlet and the water outlet at the corresponding position of the unit-type water distributor. The invention is used for the unit type water distribution device for the large-scale heat storage water tank.
Description
The technical field is as follows:
the invention relates to a unit type water distribution device for a large-scale heat storage water tank.
Background art:
in 2016, 14 days, the national energy agency has reached the notification of thermal power flexibility modification test point projects, the flexibility modification of thermal power plants in northeast and inner Mongolia power plants is mainly that thermal power units are subjected to deep peak regulation, boilers and steam turbines are correspondingly modified, the requirement of heat supply output during low-load operation is met, abundant heat is stored during high-load operation, thermoelectric decoupling is realized, and a heat storage system is additionally arranged in the units.
The heat storage system is usually provided with only one water storage tank, hot water and cold water exist in the tank at the same time, and a temperature gradient layer is naturally formed at a cold-hot water interface. However, the diameter of the water tank is large, and is usually more than twenty meters, so that the phenomenon of uneven water inlet and outlet amount in the water tank is easy to occur in the water inlet and outlet process of the water tank, and the inclined temperature layer at the junction of cold water and hot water is extremely easy to be damaged due to the disturbance of the water inlet and outlet, thus the normal use of the system is seriously influenced.
The invention content is as follows:
the invention aims to solve the problems that the water inlet and outlet quantity in a water tank is uneven and an inclined temperature layer at the boundary of cold water and hot water is easily damaged due to disturbance of the water inlet and outlet in the water inlet and outlet process of the water tank at present, and provides a unit type water distribution device for a large-scale heat storage water tank, which can ensure that the cold water and the hot water in each layer in the water storage tank are uniformly distributed and the inclined temperature layer is stable and is not damaged.
The above purpose is realized by the following technical scheme:
the unit type water distribution device for the large-scale heat storage water tank comprises a unit type water distributor, a plurality of water distribution branch pipes and a water distribution main pipe, wherein the unit type water distributor is uniformly provided with a plurality of water inlets and water outlets, the water inlets and the water outlets are arranged on the unit type water distributor in a radial mode, the water distribution branch pipes are arranged in a radial mode and are communicated with the water distribution main pipe, and each water distribution branch pipe is communicated with the water inlets and the water outlets at the corresponding positions of the unit type water distributor.
The unit type water distributor for the large-scale heat storage water tank is characterized in that the unit type water distributor, the plurality of water distribution branch pipes and the water distribution main pipe are welded into an integrated structure.
The unit type water distribution device for the large-scale heat storage water tank is characterized in that the water distribution branch pipe and the unit type water distributor belong to different cross sections.
Has the advantages that:
1. the invention can ensure that cold water and hot water in each layer in the water storage tank are uniformly distributed, and the inclined temperature layer is stable and not damaged.
2. Under the working condition of water inlet, water enters the unit type water distributor through the water distribution main pipe and the water distribution branch pipe in sequence and then is uniformly diffused to the water storage tank. And under the water outlet working condition, the flow direction is opposite. The device can solve the problem of uneven water temperature between local layers in the water storage tank caused by water inlet and outlet of the large-diameter water storage tank, can reduce the disturbance influence of the flow of the inlet and outlet water on a medium thermocline in the water storage tank, and can bring great convenience for purchasing and installing the water distribution device.
3. The number of the unit-type water distributors, the sizes of the openings and the number of the openings are obtained by calculating the water inlet and outlet quantity, the size and the flow speed of the openings are controlled, the pressure loss at each position is equal, and the small hole flow balance is further controlled.
