Problems solved by technology

In the traditional dehumidifier, due to the high content of water vapor in the working environment, the heat exchanger is easily eroded and oxidized by the humid air when exchanging heat with the air, which in turn causes damage to the heat exchanger and affects the normal operation of the electrical equipment of the hydropower station.

Embodiment 1

[0022] Such as Figure 1 to Figure 3 As shown, an air dryer for a machine room of the present invention includes a casing 1, on which an air inlet 2, an air outlet 3, a regeneration air inlet 4, and a regeneration air outlet 5 are provided. A fan 6, a heater 8, a dehumidification rotor 9 and a regeneration fan 7 are installed in the housing 1. One end of the fan 6 is connected to the air inlet 2, and the other end of the fan 6 is connected to the air outlet 3. The output of the motor 11 The end is connected with a pulley 12 and a tension adjustment mechanism is installed on the pulley 12. The belt 10 bypasses the pulley 12 and the tension adjustment mechanism is connected to the dehumidification runner 9; it also includes a water blocking plate, the blocking The water pan 20 is arranged on the inner wall of the casing 1 and communicates with the air inlet 2. The water baffle 20 is of a funnel shape, and an annular groove is installed on its large diameter end. The casing 1 is p...

Embodiment 2

[0025] Such as figure 2 with image 3 As shown, this embodiment is on the basis of embodiment 1, a roller 14 arranged tangentially to the pulley 12, the pulley 12, the roller 14 and the dehumidifying wheel 9 are connected by the belt 10, and the roller 14 and the belt 10 A pressure sensor 19 is installed at the tangent point. The pulley 12 and the roller 14 are connected by a connecting rod 13. A bracket 17 is arranged in the casing. A cylinder 18 and a plurality of fixed pulleys 16 are installed on the bracket 17. The pressure sensor 19 is connected with The driving device of the cylinder 18 is connected, a plurality of fixed pulleys 16 are symmetrically arranged on both sides of the output end of the cylinder 18, the two ends of the rotating shaft of the roller 14 are connected with a traction wire 15, and the traction wire 15 bypasses the two fixed pulleys 16 and the cylinder 18 The output end forms a pulley block. The motor 11 drives the dehumidification wheel 9 to rotate ...

Embodiment 3

[0027] Such as image 3 As shown, in this embodiment on the basis of Embodiment 1, the connecting rod 13 is an elastic plastic rod, and both ends of the elastic plastic rod are sleeved on the rotating shafts of the pulley 12 and the roller 14 respectively. In order to prevent the roller 14 from moving with the belt 10 when it rotates, the connecting rod 13 connects the pulley 12 with the roller 14. When the roller 14 is pulled at the output end of the cylinder 18, the connecting rod 13 made of elastic plastic will deform slightly. It adapts to the movement of the roller 14 while ensuring the advantageous support of the roller 14.

Abstract

The invention discloses an air drier for a machine room. The air drier for the machine room comprises a housing in which a draught fan, a heater, a rotary desiccant wheel and a regeneration blower are mounted, wherein a belt is arranged round a belt wheel and a tension adjusting mechanism to be connected with the rotary desiccant wheel. The air drier for the machine room further comprises a funnel shaped water stopping plate which is arranged on the inner wall of the housing and communicates with an air inlet; an annular groove is formed in one big-diameter end of the water stopping plate; pores are formed in the housing; the annular groove communicates with the outside through the pores. According to the air drier for the machine room, the tensioning force of the belt is reduced after the rotary desiccant wheel works for a long time; the unstable running of the rotary desiccant wheel leads to the decrease of the dehumidifying effect; the arranged tension adjusting mechanism can timely feed back the state that the work of the rotary desiccant wheel is unbalanced due to the decrease of the tensioning force of the belt and timely recover the tensioning force of the belt, thus the working stability of the rotary desiccant wheel can be ensured, and meanwhile, the dehumidifying efficiency of the rotary desiccant wheel can be improved.

Description

Technical field [0001] The invention relates to a dehumidifier, in particular to an air dryer used in a machine room. Background technique [0002] Hydropower station is a comprehensive engineering facility that converts water energy into electrical energy, also known as hydropower station. It includes a series of hydropower station buildings and various hydropower station equipments built to use hydropower to produce electricity. Use these buildings to concentrate the drop of natural water flow to form a water head, collect and adjust the flow of natural water flow, and send it to the turbine. Through the combined operation of the turbine and the generator, the concentrated water energy is converted into electrical energy, and then through the transformer and switch Stations, transmission lines, etc. input electrical energy into the grid. In conventional hydropower stations and tidal power stations, it is a hydro-generator unit composed of hydro-turbines and hydro-generators, ...
