Abstract
The utility model discloses an air exhaust harm-reduction device which comprises an air exhaust pipeline. An adsorption device is arranged on an air channel of the air exhaust pipeline, and adsorbing materials are filled in the adsorption device. Compared with the prior art, the air exhaust harm-reduction device can adsorb harmful gases in exhaust gases. In addition, the adsorption device can also block particulate matters in the exhaust gases, and secondary pollution to atmosphere of harmful substances can be reduced.
Description
Technical field
The utility model belongs to a kind of air exhausting device, is specifically related to the air exhausting device of a kind of recyclable pernicious gas and granule phase substance.
Background technology
At present, a lot of public places all are provided with smoking room, and as a kind of place with specific use, its inner space has been full of a large amount of flue gas pernicious gases and granule phase substance.For making the smoking room internal environment comfortable, healthy, then need indoor flue gas is discharged.If directly these gases are discharged, can cause secondary pollution again.So when discharging these gases, be necessary that the pernicious gas that smoking is produced reclaims by an isolated plant.
In addition, the high volatility of the test indoor section reagent of scientific research institution is inflammable and explosive mostly, usually, ventilation equipment has been installed all in laboratory, and single these ventilation equipment are not handled the gas of discharging, and have secondary pollution equally.
Summary of the invention
Given this, the purpose of this utility model is to provide a kind of ventilation unit of eliminating secondary pollution.
For solving above technical problem, the technical scheme that the utility model provides is, a kind of air draft harm reduction device is provided, comprise exhaust duct, the air channel of described exhaust duct is provided with adsorbent equipment, this adsorbent equipment inside is filled with sorbing material, and described sorbing material skin is provided with ventilative cloth bag wrapper.
Preferably, on the air channel of described exhaust duct blower fan is installed also.
Preferably, described blower fan is installed in exhaust outlet or the inlet scoop of exhaust duct.
Preferably, on the exhaust outlet of described exhaust duct water fender is installed.
Preferably, described exhaust duct is L shaped or cylindricality.
Preferably, the exhaust outlet of described exhaust duct is higher than the inlet scoop.
Preferably, described adsorbent equipment is connected by bolt with exhaust duct or is threaded.
Compared with prior art, this novelly has following characteristics:
1, because at exhaust duct adsorbent equipment being installed, filled sorbing material in this adsorbent equipment, just adsorbent can adsorb the pernicious gas in institute's emission gases.Simultaneously, adsorbent equipment can also stop the granule phase substance in institute's emission gases.
2, adsorbent equipment adopts bolt to be connected with exhaust duct or is threaded, and is convenient for changing adsorbent equipment or changes its inner adsorbent.Usually, adsorbent is after long-term the use, and its adsorbed pernicious gas is saturated gradually, and adsorption capacity reduces gradually.This device can easily be changed adsorbent equipment or change adsorbent, improves the adsorption capacity of adsorbent equipment.Adsorbent adopts adsorbent commonly used, for example activated carbon, silica gel etc.
3, the exhaust outlet of exhaust duct is higher than the inlet scoop, utilizes draught head can realize the circulation of air.That is to say that indoor high pressure draught flows to the low-pressure area of outdoor eminence by exhaust duct.When the exhaust outlet air flowed, the low pressure of exhaust outlet low-pressure area was more obvious, and therefore the air draft ability of air exhausting device can improve.
4, at exhaust duct adsorbent equipment has been installed, will inevitably increase air by the resistance of this exhaust duct, one blower fan is installed in exhaust duct, this blower fan can be installed in the inlet scoop of exhaust duct to increase draft capacity, perhaps be installed in exhaust outlet to increase the air draught ability, thereby the air draft ability that guarantees air exhausting device is unaffected, even improves its air draft ability.
5, on the exhaust outlet of exhaust duct water fender has been installed, can have been avoided the rainy day rainwater to enter exhaust duct, prevented that adsorbent from being soaked, influenced the adsorption capacity of adsorbent.
Description of drawings
Fig. 1 is this novel preferred embodiment cutaway view.
The specific embodiment
Describe below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1.The described air draft harm reduction of present embodiment device comprises exhaust duct 1, and this exhaust duct 1 is L shaped, and exhaust outlet is positioned at the top of described exhaust duct 1, and the inlet scoop is positioned at the bottom of exhaust duct.Vertical section of exhaust duct 1 is provided with adsorbent equipment 2, and adsorbent equipment 2 and exhaust duct 1 are connected by bolt, also can be by being threaded.These adsorbent equipment 2 inside are filled with sorbing material 3.The close exhaust outlet annex of exhaust duct 1 is equipped with the blower fan 5 that can improve device air draught ability.Water fender 4 is installed on the exhaust outlet of exhaust duct 1.
As another kind of embodiment, exhaust duct 1 can be cylindricality, compares with L shaped exhaust duct, default horizontal segment.
Only be preferred embodiment of the present utility model below, should be pointed out that above-mentioned preferred embodiment should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
