Problems solved by technology

[0004] Due to the high temperature of the air in the heating pipeline of the current hot air heating device, high temperature is prone to occur near the air outlet of the pipeline, which affects the growth of crops and causes the death of crops near the air outlet due to high temperature. Therefore, it is necessary to provide a device that can Hot air heating device to prevent overheating of the air outlet

Embodiment 1

[0023] see figure 1 , figure 2 and Figure 4 As shown, the present invention is a hot air temperature increasing and dehumidifying device for a greenhouse, comprising a heater 1, a main pipe 2 connected to the air outlet of the heater 1, a branch pipe 3 connected to the main pipe 2, and the surface of the branch pipe 3 is provided with a The grid-shaped exhaust holes 4 are evenly distributed in the axial direction.

[0024] Wherein, the branch pipes 3 are arranged in parallel at equidistant intervals along the axial direction of the main pipe 2 , and the branch pipes 3 are symmetrically distributed on both sides of the main pipe 2 .

[0025] The technical parameters of the hot air heating and dehumidification device are calculated and designed as follows:

[0026] 1. Estimation of the maximum heating load

[0027] The size of the heating load is constantly changing with the outdoor temperature. The supplementary heat required to maintain the normal growth of crops in the...

Embodiment 2

[0090] see image 3 As shown, compared with Embodiment 1, this embodiment only changes the distribution position of the branch pipe 3, so that the branch pipe 3 is distributed on one side of the main pipeline 2, and correspondingly changes the number and length of the branch pipe: the length of the branch pipe 3 is 8 meters , the quantity is 16 pieces.

Abstract

The invention discloses a hot-air temperature increasing and humidity reducing device for a greenhouse, and relates to the technical field of hot-air temperature increasing. The device comprises a fanheater, a main pipeline and a branch pipe, the main pipeline is connected with a fan heater air outlet, the branch pipe is connected with the main pipeline, and lattice exhaust holes are uniformly distributed on the surface of the branch pipe along the axial direction of the branch pipe. According to the device, dense lattice small holes are formed in the branch pipe, high temperature and high pressure at an outlet are sufficiently avoided, so that the temperature is uniformly distributed, air humidity can be uniformly reduced, and death of parts of crops caused by high temperature can be effectively reduced when heat supply of the greenhouse is effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of hot air temperature increase, in particular to a hot air temperature increase and dehumidification device for greenhouses. Background technique [0002] In the greenhouse planting industry, reasonable temperature increase can ensure the good growth of crops. Hot air heating is a heating method that sends heated air directly into the greenhouse through a heat exchanger to increase the room temperature. Because this method is forced heating air, the efficiency of heating is high. The way to heat the air with hot air is to use hot water or steam to exchange heat through the heat exchanger and then blow the hot air into the room by a fan, or to directly burn the air in a heating furnace. The former is called hot air, and the latter is called hot air stove. Air heaters include heaters, hot water heaters, and steam heaters, which are classified according to the fuel they burn. There are two methods of transp...
