By the description of its exemplary embodiment being carried out below in conjunction with accompanying drawing, the above-mentioned feature and advantage of the utility model will become apparent and easily understand.

Fig. 1 is the overall structure schematic diagram of the energy-conservation booth of the utility model embodiment;

Fig. 2 is the schematic perspective view of the utility model embodiment vent cabinet.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail, so that technical staff's of the same trade understanding:

As shown in Figure 1-2, label represents respectively:

Controller 1, blower fan 2, cabinet 3, wet curtain 4, water supply line 5, deep well 6, underground tank 7, water return pipeline 8, canopy body 9, temperature sensor 10, humidity sensor 11, gas concentration lwevel sensor 12.

Shown in Figure 1, the livestock and poultry cultivation or the energy-conservation booth of planting that a kind of Wet-curtain type decreasing temperature and increasing humidity vent cabinet are provided in the present embodiment and there is this vent cabinet.Wherein:

Wet-curtain type decreasing temperature and increasing humidity vent cabinet comprises the cabinet 3 with air inlet and air outlet, and the mandatory blower fan 2 of air outlet that air is sent to from air inlet, and air outlet quantity is two in the present embodiment, and is respectively provided with a negative-pressure air fan.In described cabinet 3, between described air inlet and air outlet, set up successively the wet curtain 4 in three roads, the top of described wet curtain 4 is communicated with water supply line 5, and water supply line 5 is communicated with cold water source, such as deep well etc.Bottom in cabinet 3 is also provided with tank, for water is discharged outside cabinet.In addition, described vent cabinet also comprises controller 1 and is located at temperature sensor 10, humidity sensor 11 and the gas concentration lwevel sensor 12 outside described cabinet, described controller 1 connects described temperature sensor 10, humidity sensor 11 and gas concentration lwevel sensor 12, and the magnetic valve on blower fan 2 and described water supply line 5 described in control connection.

The energy-conservation booth that the present embodiment provides, comprises the canopy body 9 of producing for animals and plants, also comprises vent cabinet as above.Described vent cabinet be located on canopy body opening part, its exhaust outlet is positioned at canopy, air inlet is positioned at outside canopy, with mandatory, the external air of canopy is sent in canopy body.And temperature sensor 10, humidity sensor 11 and gas concentration lwevel sensor 12 are located in described canopy body.In addition, in described energy-conservation booth, also comprise underground tank 7 and deep well 6.Described water supply line 5 is communicated with respectively described underground tank 7 and deep well 6 via water pump, and the tank of described vent cabinet bottom is communicated to described underground tank 7 by water return pipeline 8.

By said structure, in the present embodiment, adopt cold water in deep well 6 as cooling medium, adopt and establish again wet curtain 4, by the space buffer in cavity, successively lower the temperature.Outlet temperature is down to lower, reaches various animals and plants production requirements.

Controller 1 detects canopy internal state by temperature sensor 10, humidity sensor 11 and gas concentration lwevel sensor 12, when in booth being detected, gas concentration lwevel surpasses setting value, open blower fan 2 and carry extraneous fresh air in booth, waste gas is depressed into outdoor; Meanwhile, if when temperature surpasses setting value or humidity lower than setting value, also open the magnetic valve on water supply line 5, air-flow is by the cold water humidifying cooling in wet curtain 4., when being down to applicable temperature, humidity, close the magnetic valve on water supply line 5.In canopy, automatically close blower fan 2 during the near debita spissitudo of carbon dioxide.

This scheme is simple and practical, and the relative air-conditioning of power consumption significantly reduces.Owing to adopting the cold water cooling of underground deep water well water, can not damage environment, wet curtain paper can effectively filter dust, pernicious gas and peculiar smell simultaneously, improves in booth with fresh air simultaneously.

By embodiment, for invention intention of the present utility model and embodiment, be elaborated above; but the utility model one of ordinary skill in the art be appreciated that; the above embodiment of the utility model is only one of preferred embodiment of the present utility model; for length restriction; here can not all embodiments of particularize; any enforcement that can embody the utility model claim technical scheme, all in protection domain of the present utility model.

For example the selection for wet curtain quantity is not limited only to this, when needs cooling extent little, and ventilation needs when larger suitably to reduce wet curtain quantity, and when needing cooling extent larger, and wind flux needs when lower, can suitably increase wet curtain quantity, so those skilled in the art can to increase and decrease arbitrarily to its quantity according to concrete operating mode when implementing, preferably, wet curtain quantity is at 2-3.Measuring for example, 38 ° of C of extraneous space temperature, 17 ° of C of deep well water temperature, after one Wet-curtain temperature reducing, temperature is down to 28 degree, after secondary Wet-curtain temperature reducing, temperature is down to 23 ° of C, after three grades of Wet-curtain temperature reducings, temperature is down to 20 ° of C, so the wet curtain of 2-3 level can reach the temperature requirement of animals and plants Production requirement.

Meanwhile, whether the setting of underground tank and deep well is also not limited only to embodiment, and it is determined in two kinds of situation:

If cold water source picked-up expense is lower, and require the amplitude of cooling larger, can not establish underground tank, water at low temperature is directly discharge after using.

If the picked-up expense of cold water source is less compared with amplitude large and that require to lower the temperature, underground tank can be set, the top of underground tank should be below 1.5m apart from natural terrace.Backwater can be recycled after lowering the temperature in underground tank.

If near while not having condition to dig the condition of deep well, underground tank also can be only set and carry out water circulation, utilize the low feature of the relative air themperature of subsurface temperature in summer to reduce water temperature.

It should be noted that; above content is in conjunction with concrete embodiment further detailed description of the utility model; can not assert that the specific embodiment of the present utility model only limits to this; under the guidance of above-described embodiment; those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improvement or distortion drop in protection domain of the present utility model.
