Description

Technical Field

[0001] This utility model belongs to the technical field of heating and humidification equipment, and in particular relates to a heating and humidification device that combines an ultra-low ambient temperature heat pump with a wet film humidifier. Background Technology

[0002] In cold regions, the air conditioning systems in cigarette factories' tobacco storage rooms and leaf storage rooms mostly rely on steam from the power center for heating and humidification, which results in significant energy consumption.

[0003] For example, Chinese utility model patent application number 202321203819.9 discloses a steam thermal system for cigarette factories, which relates to the field of thermal power engineering technology. The system includes a boiler (1), a heat accumulator and a boiler steam distribution system. The steam generated by the boiler (1) is converted into saturated steam by the steam heat accumulator (7) and enters the cigarette making steam distribution cylinder (9). The steam is supplied to the vacuum rehumidification steam line (10), the main cigarette making process steam line (11), the cigarette making air conditioning room steam line (12) and the cigarette packaging air conditioning room steam line (13) through the four output ports of the cigarette making steam distribution cylinder (9).

[0004] The aforementioned system equipment consumes a large amount of energy, which also increases production costs. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a heating and humidification device that combines an ultra-low ambient temperature heat pump with a wet film humidifier, thereby achieving the effect of saving equipment energy consumption and reducing production costs.

[0006] In view of this, the present invention provides a heating and humidification device combining an ultra-low ambient temperature heat pump and a wet film humidifier, comprising:

[0007] Ultra-low ambient temperature heat pump, placed outdoors, used to produce hot water, has inlet and outlet pipes;

[0008] A wet film humidifier, placed indoors for humidifying the environment, includes a housing and a first water inlet, a first wet curtain, and a first blower disposed within the housing;

[0009] The water outlet pipe passes through the outer shell and is connected to the first water inlet. A valve is provided on the water outlet pipe. The first water inlet is located above the first wet curtain and is used to spray hot water onto the wet curtain. The first blower is aligned with the first wet curtain. The outer shell is provided with a first air outlet for the first blower. The first blower is used to blow out the hot and humid air generated by the first wet curtain through the first air outlet.

[0010] In this technical solution, an ultra-low ambient temperature heat pump is used to produce hot water at 50-55℃ under cold outdoor conditions, which is then transported to a wet film humidifier and blown into the room (fiber storage room, leaf storage room) to replace the steam heating and humidification in the existing technology. The independent low-temperature heat source saves equipment energy consumption, reduces the waste of manpower and material resources, and reduces production costs.

[0011] Furthermore, the housing includes a controller, a first water collection tray, a first drain pipe, and a first liquid sensor;

[0012] The controller includes a power supply and a PLC connected by wires. The first water collection tray is located below the first wet curtain to collect hot water falling from the wet curtain. The first drain pipe is located on the lower side of the first water collection tray and is equipped with a first water pump connected to the PLC by a first wire. The first liquid sensor is located in the middle of the inner wall of the first water collection tray and is connected to the PLC by a second wire. When the water level in the first water collection tray reaches the position of the first liquid sensor, the PLC controls the first water pump to drain water according to a preset program.

[0013] Furthermore, the housing is provided with a central upright plate, the first wet curtain, the first blower, the first water collection tray, the first drain pipe and the first water pump are located on one side of the central upright plate, and the controller is detachably located on one side of the upright plate by bolts;

[0014] On the other side of the central upright plate, there is a second wet curtain and a second blower. Above the second wet curtain, there is a second water inlet. The second water inlet is connected to the first drain pipe through a connecting pipe. The second blower is aligned with the second wet curtain. The outer shell is provided with a second air outlet for the second blower. The second blower is used to blow out the hot and humid air generated by the second wet curtain through the second air outlet.

[0015] Furthermore, a second water collection tray is provided below the second wet curtain. The second water collection tray is used to collect the hot water falling from the second wet curtain, and a second drain pipe is provided on the lower part of the other side of the second water collection tray, which extends out of the outer casing. A second water pump is provided on the second drain pipe.

[0016] The second water collection pan is equipped with a second liquid sensor on the upper part of its inner wall. The second liquid level sensor is connected to the PLC via a third wire, and the second water pump is connected to the PLC via a fourth wire. When the water level in the second water collection pan reaches the position of the second liquid sensor, the PLC controls the second water pump to drain water according to a pre-set program.

[0017] Furthermore, a water distributor is provided between the first water inlet and the first wet curtain, and between the second water inlet and the second wet curtain, to evenly spray the hot water from the first water inlet and the second water inlet onto the corresponding first wet curtain and second wet curtain.

[0019] Furthermore, protective mesh covers are provided at both the first and second air outlets, and the outer casing has a small door for aligning with the controller.

[0020] The beneficial effects of this utility model are:

[0021] 1. By using an ultra-low ambient temperature heat pump to produce hot water at 50-55℃ in cold outdoor conditions, the water is then transported to a wet film humidifier and blown into the room (silk storage room, leaf storage room) to produce hot and humid air. This replaces the existing steam heating and humidification technology. By using an independent low-temperature heat source, energy consumption of equipment is saved, and waste of manpower and material resources is reduced. At the same time, production costs are reduced. Using an ultra-low ambient temperature heat pump to provide hot water in cold regions reduces steam energy consumption and eliminates the need for a power center in the cigarette factory. This fully utilizes the heat source and solves the energy mismatch problem of overcapacity in non-production periods.

[0022] 2. The first water collection tray can catch the hot water falling from the first wet curtain, preventing the hot water from falling into the outer casing and affecting the normal use of the wet film humidifier. When the water level in the first water collection tray reaches the position of the first liquid sensor, the PLC controls the first water pump to drain the water through the first drain pipe according to the preset program, preventing hot water from overflowing the first water collection tray. The automation level is high, reducing the intensity of manual labor. The water discharged through the first drain pipe can be used for other purposes (such as toilet water, watering plants, etc.).

[0023] 3. The first drain pipe can deliver water with residual heat to the second water inlet and the second wet curtain through the connecting pipe. The second blower is used to blow the hot and humid air generated by the second wet curtain out through the second air outlet, so as to make full use of the hot water produced by the ultra-low ambient temperature heat pump, resulting in higher energy utilization and further reducing production costs.

[0024] 4. The second water collection tray can catch the hot water falling from the second wet curtain, preventing the hot water from falling into the outer casing and affecting the normal operation of the wet film humidifier. When the water level in the second water collection tray reaches the position of the second liquid sensor, the PLC controls the second water pump to drain the water through the second drain pipe according to the preset program, preventing hot water from overflowing the second water collection tray. It has a high degree of automation and reduces the intensity of manual labor. The water discharged through the second drain pipe can be used for other purposes (such as toilet water, watering plants, etc.).

[0025] 5. The arrangement of multiple nozzles allows the water distributor to evenly spray hot water onto the corresponding first and second wet curtains, resulting in higher humidification efficiency.

[0026] 6. The protective mesh cover can isolate the first and second blowers, providing higher safety, and the small door facilitates the installation of the controller. Attached Figure Description
