Description

Technical Field

[0001] This invention relates to a humidifier that uses a medium for heating. Background Technology

[0002] In the prior art, Chinese invention patent document, publication number CN110500183B, discloses a combined cooling, heating, and power gas turbine unit, including a gas generator set, a chimney, a hot water absorption chiller unit, an air conditioning and heating heat exchanger, a domestic hot water heat exchanger, an air conditioning distributor, and a water cooling tank. The gas generator set is connected to a gas pipeline, and the gas generator set is connected to the chimney via a flue gas pipeline. An internal cooling water tank is installed in the gas generator set. The chimney contains, in sequence, a first flue gas absorption hot water unit, a first flue gas absorption chiller unit, a second flue gas absorption hot water unit, and a second flue gas absorption chiller unit. Beneficial effects: Using gas as the core energy source, and through full recovery and multi-stage utilization of the unit's waste heat, it meets the comprehensive needs for electricity, cooling and heating, domestic hot water, and other hot water needs, achieving a primary energy utilization rate of up to 85%, representing a novel regional energy-saving application model.

[0003] Existing mist-free humidifiers, such as those disclosed in Chinese invention patent application document CN114151891A, include a housing, a fan, an electric heating element, and a wet curtain. The housing has an air inlet and an air outlet, the electric heating element has an air passage gap, and the housing has a water storage chamber for supplying water to the wet curtain. The fan, the electric heating element, and the wet curtain are sequentially arranged in the housing along the airflow direction from the air inlet to the air outlet. The fan and the electric heating element are spaced apart along the airflow direction, and the fan blows air towards the electric heating element. The hot air heated by the electric heating element is delivered to the wet curtain to heat the water adsorbed by the wet curtain into steam, which is then discharged from the air outlet.

[0004] Based on the above, in the existing technology, existing mist-free humidifiers require the use of electric heating elements to heat the incoming air. This heating method using electric heating elements not only requires each humidifier to be equipped with heating elements, thermostats, and controllers, but also greatly increases production costs and needs further improvement. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. In order to reduce the use of components and production costs, this invention proposes a humidifier that is connected to an external combined cooling, heating and electric gas turbine unit and uses medium heating.

[0006] A humidifier designed for this purpose, employing a heating medium, includes a base, on which a wet curtain assembly is mounted, a fan assembly is disposed within the wet curtain assembly, an outer cover is mounted on the base outside the wet curtain assembly, air inlets are evenly distributed on the outer cover, a heating medium pipe is provided between the outer cover and the wet curtain assembly, an upper cover is mounted on the outer cover, an air outlet is provided on the upper cover, and a conveying assembly for conveying liquid to the wet curtain assembly is installed on the upper cover. The first input end and the first output end of the heating medium pipe are both connected to an external combined cooling, heating and electric gas turbine unit.

[0007] Compared to existing technologies, this invention involves an external device connected to a heating medium pipeline. This external device supplies heating medium to the pipeline, allowing heat to radiate to the surrounding air. Simultaneously, a conveying component supplies liquid to the evaporative cooling pad assembly, enriching it with moisture. Under the action of a fan assembly, external air enters from the outer casing, passing through the heating medium pipeline and the evaporative cooling pad assembly. The air is heated and mixes with the water molecules in the evaporative cooling pad assembly before being output from the outlet. This invention, by connecting an external heating medium supply device to the internal heating medium pipeline of the humidifier, reduces the number of heating elements required. In large apartment buildings, one or more units can be connected to the humidifier in each apartment, minimizing the number of components within the humidifier and reducing manufacturing costs.

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] See Figures 1-4A humidifier using medium heating includes a base 10, on which a wet curtain assembly 30 is disposed, and a fan assembly 70 is disposed inside the wet curtain assembly 30. An outer cover 40 is disposed on the base 10 outside the wet curtain assembly 30. Air inlets 410 are evenly distributed on the outer cover 40. A heating medium pipe 50 is provided between the outer cover 40 and the wet curtain assembly 30. An upper cover 800 is disposed on the outer cover 40. An air outlet 801 is disposed on the upper cover 800. A conveying assembly 60 for conveying liquid to the wet curtain assembly 30 is installed on the upper cover 800. The first input end and the first output end of the heating medium pipe 50 are both connected to an external combined cooling, heating and electric gas turbine unit.

[0014] The working principle of this invention involves an external device connected to a heating medium pipeline, which supplies the heating medium to the humidifier. This heat is then dissipated through the pipeline, heating the surrounding air. Simultaneously, a conveying component supplies liquid to the evaporative cooling pad assembly, enriching it with moisture. Under the action of a fan assembly, external air is drawn in from the outer casing, passing through the heating medium pipeline and the evaporative cooling pad assembly. The air is heated and mixes with the water molecules in the evaporative cooling pad assembly before being output from the outlet. This invention utilizes an external combined cooling, heating, and electric gas turbine unit connected to the heating medium pipeline inside the humidifier, reducing the need for heating elements.

[0015] This invention can be used in some large apartment buildings. One or more units can be connected to the humidifier in each apartment, which can minimize the number of components in the humidifier and reduce manufacturing costs.

[0016] See Figure 3 The base 10 is provided with a mounting base 100, and the mounting base 100 is provided with an insertion cavity with an upper opening, and the lower end of the wet curtain assembly 30 is inserted into the insertion cavity.

[0017] The evaporative cooling pad assembly 30 includes a housing 310 with an opening at its lower end. An evaporative cooling pad 320 is inserted into the housing 310. A through-vent 311 is provided on the housing 310. A water seepage groove 330 is provided on the upper end of the housing 310. Multiple downward water seepage holes 340 are arranged in the water seepage groove 330. The conveying assembly 60 conveys liquid into the water seepage groove 330. The liquid seeps downward into the interior of the evaporative cooling pad 320 through the water seepage holes 340, making the interior of the evaporative cooling pad 320 rich in moisture.

[0018] The heating medium pipe 50 is disposed between the outer cover 40 and the housing 310. Under the action of the fan assembly 70, external air enters from the outer cover 40, contacts the heating medium pipe 50, and then passes through the wet curtain 320 and the housing 310 before being output upward.

[0019] See Figure 1 The conveying assembly 60 includes a three-way pipe 610 disposed on the upper cover 800. The input end of the three-way pipe 610 is connected to a liquid input pipe 802. The first output end of the three-way pipe 610 is connected to a first pipe fitting 630. An electric valve 640 is installed on the first pipe fitting 630. The first pipe fitting 630 extends into the seepage tank 330.

[0020] The external water supply pipe is connected to the liquid input pipe 802. Under the action of the three-way pipe 610, the liquid is transported to the first pipe fitting 630. When the electric valve 640 controls the opening and closing, the liquid can be transported to the seepage tank 330 in the open and closed state.

[0021] Further, see Figure 1 The second output end of the three-way pipe 610 is connected to a second fitting 620, which is connected to the second input end of the heating medium pipe 50. A second valve is also installed on the second fitting 620. A third fitting is also connected to the second output end of the heating medium pipe 50, and a third valve is installed on the third fitting.

[0022] Furthermore, a fourth valve is provided at both the first input end and the first output end of the heating medium pipeline 50. The heating medium pipeline 50 of the present invention employs two methods for inputting the heating medium.

[0023] In the first method, the second and third valves are closed, and the two fourth valves are open. At this time, the heating medium pipeline 50 is connected to the external equipment, and the external equipment supplies heating medium to the heating medium pipeline 50. The heating medium can flow back from the first output end to the inner wall of the external equipment.

[0024] The second method involves two fourth valves being closed, while the second and third valves are open. In this state, the heating medium pipeline 50 is not connected to the external equipment. In this state, hot water is supplied to the tee pipe 610 through the conveying component 60, and the hot water is supplied to the seepage tank 330 to wet the wet curtain 320. At the same time, the hot water can also be transported into the heating medium pipeline 50 to heat the air.

[0025] The electric valve 640 uses an existing solenoid valve. The function of the electric valve 640 is to control the opening and closing of the first pipe fitting 630 to prevent water from being continuously supplied into the seepage tank 330.

[0026] See Figure 3The fan assembly 70 includes a mounting housing 710 with an opening at the top. A wind trough 740 is provided on the side wall of the mounting housing 710. A motor 720 is installed inside the mounting housing 710. A fan wheel 730 is installed on the motor shaft of the motor 720. An air guide shroud 750 is provided on the mounting housing 710, extending upward and fitting against the inner top surface of the upper cover 800. The air outlet 801 is in communication with the air guide shroud 750.

[0027] When the machine is running, the motor 720 is powered on and starts, driving the fan wheel 730 to rotate. It can draw outside air into the interior through the outer cover and then output it from the air outlet. During this process, the air entering the interior will first be introduced by the heating medium pipe 50 and then mixed with water molecules in the wet curtain 320 to increase the air humidity and heat the air.

[0028] In this invention, the mounting housing 710 is fixedly connected to the housing 310.

[0029] In this invention, the lower end of the housing 310 is inserted into the insertion cavity of the mounting base 100, the upper end of the housing 310 is threadedly connected to the upper end of the outer cover 40, and the lower end of the outer cover 40 is threadedly connected to the base 10.

[0030] In this invention, the upper cover 800 and the outer cover 40 are fastened together.

[0031] In this invention, a water tank 20 for collecting return water is connected below the base 10, a drain pipe 201 is installed on the water tank 20, a drain outlet 101 for connecting the insertion cavity and the water tank 20 is provided on the mounting base 100, and a guide shroud 810 is installed on the air outlet 801.

[0032] Specifically, a drain pipe 201 is installed on the water tank 20. The function of the drain pipe 201 is to drain the backflow water in the water tank 20. Water that seeps down from the seepage hole into the wet curtain flows down through the drain outlet 101 into the water tank 20 for collection. The function of the drain pipe 201 is to achieve automatic drainage, which cannot be manually operated.

[0033] In this invention, the heating medium pipeline 50 is arranged in a spiral tube shape.

[0034] In this invention, the water tank 20 is detachably connected to the base 10.
