Description

Technical Field

[0001] The utility model belongs to the technical field of condensed water recovery equipment, and in particular relates to a condensed water recovery device for a heat exchange station with a heat recovery structure. Background Art

[0002] The condensate recovery device of the heat exchange station refers to the equipment used to recover and utilize the condensate of the heat exchange station. It collects the condensate in the heat exchange station system and treats it for reuse or discharge. Condensate is generated during the heat exchange process. When the water vapor is cooled to a saturated state, it condenses into liquid water. Recycling condensate can reduce the consumption of water resources and reduce the discharge of wastewater, which has the effect of energy saving and environmental protection. The device usually includes a condensate collection system, treatment facilities (such as filtration, degassing, disinfection and other treatment processes) and a reuse system (such as a water supply system, cooling water system, etc.). Through reasonable design and operation, the condensate recovery device can effectively improve the utilization rate of energy and water resources.

[0003] Some existing heat exchange station condensate recovery devices often have the phenomenon of incomplete condensate recovery. This causes the heat exchange station to directly discharge this part of the condensate that has not been recovered. The temperature of this part of condensate is generally 80 to 100 degrees. Direct discharge will cause heat waste on the one hand, and on the other hand, it will cause a lot of water vapor around the pipes and the road surface will be in a state of steam, affecting the working environment. Therefore, we hope to design a heat exchange station condensate recovery device with a new structure to solve this problem. Utility Model Content

[0006] An air inlet pipe is arranged on the upper side of the left surface of the box body, a driving motor is installed on the upper end of the box body, and the top of the box body is rotatably connected to the upper end of the reciprocating screw rod;

[0007] A scraper is movably installed inside the box body through a reciprocating screw rod, and a guide rod is fixed on the left and right sides of the top of the box body respectively;

[0008] A fixing frame is fixed on the upper side of the recycling box, a dispersion plate is welded on the upper end of the fixing frame, and a water supply pipe is arranged on the left side of the upper end of the recycling box.

[0009] As a preferred embodiment, a reducer is provided at one end of the air inlet pipe close to the box body, and the diameter of the reducer gradually increases from left to right. In actual use, a high-temperature resistant liquid level sensor is installed at the lower third of the inner wall of the box body, and a liquid level sensor is respectively provided at the lower third and the middle half of the inner wall of the recovery box, so as to facilitate the addition of low-temperature water and the discharge of mixed hot water.

[0012] As a preferred embodiment, an inclined plate in a U-shaped structure is arranged at an angle of 45 degrees on the outer side of the connection frame, and the lower end of the inclined plate is in sliding contact with the inner wall of the box. The setting of the scraper can prevent a large amount of condensed water from adhering to the inner wall of the box and not being able to be discharged and recovered in time.

[0013] As a preferred embodiment, a guide tube 2 is provided on the upper right side of the recovery box, the structure and size of the guide tube 2 match the structure and size of the guide tube 1, and the guide tube 1 and the guide tube 2 are symmetrically arranged about the solenoid valve axis.

[0015] After adopting the above technical solution, the beneficial effect of the utility model is as follows: by arranging a reciprocating screw, a scraper and a guide rod inside the condensation box, the condensed water on the inner wall of the box can be quickly hung down to avoid it from being attached to the inner wall of the box for a long time, and the condensed water can be collected and recycled in time;

[0016] The recovery box is set up, when the condensed water in the box reaches the position of the internal liquid level sensor, the solenoid valve opens, and the condensed water inside the box enters into the recovery box through the inclined guide pipe 1 and the guide pipe 2. When the condensed water has not entered into the recovery box, if the low-temperature water level inside is lower than the liquid level sensor at the lower third of the recovery box, low-temperature water can be added into it through the water adding pipe. After the condensed water enters, if the temperature inside the recovery box is high, low-temperature water can be transported into it through the water adding pipe. The low-temperature water is dispersed under the action of the dispersion plate and can be evenly mixed with the liquid inside the recovery box. When the temperature reaches the requirement, it can be discharged through the discharge pipe to participate in the heating cycle, which can effectively recover the heat of the condensed water, reduce the energy consumption of heating, and avoid energy waste.

[0025] An air inlet pipe 120 is disposed on the upper side of the left surface of the box body 110, a driving motor 140 is installed on the upper end of the box body 110, and the top of the box body 110 is rotatably connected to the upper end of the reciprocating screw rod 150;

[0026] A scraper 160 is movably installed inside the box 110 through a reciprocating screw rod 150, and a guide rod 130 is fixed to the left and right sides of the top of the box 110 respectively;

[0027] A fixing frame 240 is fixed to the upper side of the recovery box 200 , a dispersion plate 230 is welded to the upper end of the fixing frame 240 , and a water supply pipe 210 is arranged on the left side of the upper end of the recovery box 200 .

[0028] See also Figure 1 , Figure 3 A reducer is provided at one end of the air inlet pipe 120 close to the box body 110, and the diameter of the reducer gradually increases from left to right. In actual use, a high-temperature resistant liquid level sensor is installed at the lower third of the inner wall of the box body 110, and a liquid level sensor is provided at the lower third and the middle half of the inner wall of the recovery box 200, respectively, to facilitate the addition of low-temperature water and the discharge of mixed hot water.

[0029] A flow guide pipe 170 is disposed on the right side of the lower end of the box body 110, a solenoid valve 180 is installed on the lower side of the flow guide pipe 170, and the upper side of the flow guide pipe 170 is designed to be inclined at an angle of 40 degrees.

[0030] The scraper 160 includes an inclined plate 161, a connecting frame 162 and a connecting frame 163. The middle of the connecting frame 163 is movably connected to the reciprocating screw rod 150. The connecting frame 163 is a cross-shaped structure. The connecting frame 163 is fixedly connected to the inner wall of the connecting frame 162. The connecting frame 162 is a U-shaped structure.

[0031] An inclined plate 161 in a U-shaped structure is arranged at an angle of 45 degrees on the outer side of the connecting frame 162. The lower end of the inclined plate 161 slides against the inner wall of the box body 110.

The dispersion plate 230 is welded to the upper side of the fixing frame 240 through the support rod 231. The dispersion plate 230 is a conical structure.
