Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
As shown in fig. 1-4, the horizontal energy-saving water tank for the gas boiler comprises a tank body, wherein the tank body comprises a first water inlet 11 for accessing condensed backwater, a second water inlet 12 for accessing circulating backwater, a third water inlet 13 for accessing softened water, a water intake 14 for a water feeding pump and a water intake 15 for a circulating pump. This box is the cuboid structure and length is greater than the height, and the box is equallyd divide into hot water district 21 and cold water district 22 with the box in width direction, first water inlet 11 and second water inlet 12 are established at hot water district 21 top, and third water inlet 13 is established at cold water district 22 top. The water intake of the water supply pump 14 is arranged in the hot water area 21, and the water intake of the circulating pump 15 is arranged in the cold water area 22.
After the structure is adopted, condensed backwater and circulating backwater in the boiler loop respectively enter the hot water area of the box body through the first water inlet 11 and the second water inlet 12, and softened water is supplemented into the cold water area of the box body through the third water inlet 13. Because the temperature of condensation return water and circulation return water is higher than demineralized water far away, and first water inlet 11 and second water inlet 12 are far away from first water inlet 13 in width direction to make the inside moisturizing of box produce the phenomenon of temperature layering when mixing, the temperature that is close to first water inlet 11 and second water inlet 12 one side is higher, and the temperature that is close to third water inlet 13 one side is lower, and hot water district temperature is higher than cold water district temperature promptly. Therefore, the water with higher temperature in the hot water area 22 is pumped by the water feeding pump 31 to flow to the economizer, and the inlet water temperature of the economizer can be increased by 5-10 ℃. The energy saver supplies the water with higher temperature to the boiler, thereby not only reducing the energy consumption of the boiler, but also greatly improving the efficiency of the boiler. And the supplemented water with lower temperature in the cold water area 21 is pumped by the circulating pump 32 to flow to the condenser for heating and then flows back to the water tank. When the moisturizing flows through the condenser, because the temperature of moisturizing is lower, and the heat transfer difference between the condenser is big more, and the moisturizing endotherm is just faster. The water is supplemented to absorb the heat energy of the smoke and then flow back, and the heat energy is stored in the water tank, so that the heat energy generated by the boiler is increased, saved and utilized.
It should be noted that, in energy-conserving water tank actual operation, draw water from the bottom and just can make full use of water tank volume, satisfy the characteristic of circulating pump and feed pump, so feed pump intake 14 and circulating pump intake 15's position can only be established in the water tank bottom, this novel do not set up the baffle in the water tank, but through the design of arranging to water inlet and intake in the horizontal direction and realize the cold and hot water subregion in the water tank, let low temperature water and high temperature water just take away by circulating pump 32 and feed pump 31 before mixing, reach the effect that can its usefulness to the greatest extent.
Preferably, the length of the box body is 4.5m, the width of the box body is 2m, and the height of the box body is 2.5 m.
Preferably, the feed pump intake 14 and the circulating pump intake 15 are arranged opposite to each other along the length direction of the tank. After adopting above-mentioned structure, make feed pump intake 14 and circulating pump intake 15 apart from far away, make the suction direction of the suction stroke of feed pump and circulating pump be parallel arrangement moreover, effectively reduce two intakes and produce mutual interference's influence when the water intaking, ensure that feed pump 31 draws more hot water and circulating pump 32 draws more cold water.
Preferably, the first water inlet 11 and the second water inlet 12 are arranged along the length direction of the tank body and are arranged close to a water intake 14 of the water supply pump, and the third water inlet 13 is arranged close to a water intake 15 of the circulating pump. Adopt above-mentioned structure, feed pump intake 14 is close to first water inlet 11 and second water inlet 12, makes high temperature's condensation return water and circulation return water after the case is gone into in the backward flow, and feed pump 31 can extract the moisturizing by the very first time, prevents that condensation return water and circulation return water from mixing and reducing the temperature with the water tank moisturizing, ensures that feed pump 31 can extract the moisturizing of higher temperature. Similarly, the circulating pump intake 15 is close to the third intake 13 and is set up, and the demineralized water that the temperature is lower is drawed by the circulating pump the very first time after getting into the water tank, can ensure that circulating pump 32 draws the lower water tank moisturizing of temperature.
Preferably, the water intake of the feed pump 14 and the water intake of the circulating pump 15 are 20cm away from the bottom of the tank. Has the effect of stabilizing water pressure, and is convenient for the water supply pump 31 and the circulating pump 32 to take water.
