In this embodiment, the foul smell purification system of the garbage transfer station only works when the domestic waste is transferred, and in the non-working period, the waste is stored in the closed collection tank body, and the influence on the air quality of the garbage transfer station is not large.
The garbage transfer station is mainly municipal domestic garbage which generally contains more organic matters and a certain amount of water, and a large amount of malodorous gas is generated under the action of microorganisms in the accumulation process, wherein the malodorous gas mainly comprises ammonia gas, hydrogen sulfide gas, methyl mercaptan, methylamine, methyl sulfide and other compounds. Ammonia gas is colorless, has strong irritant gas, can enter human body through different ways such as respiratory tract and skin, has great harm to human body, and can cause symptoms such as cough, chest distress and dyspnea. Hydrogen sulfide is a colorless and smelly egg-flavored gas, and has influence on the respiratory system and nervous system of human body.
In a place with dense population, the garbage transfer station is an indispensable part. However, at the residential site near the garbage transfer station, residents are often affected by the malodorous gas dissipated by the garbage transfer station, and the nearby commercial facilities are affected to different degrees. If the berth rents descend, the passenger flow is reduced. Therefore, the air quality of the garbage transfer station is improved, and the air quality is very important in the urban central area.
The foul smell purification system (hereinafter, simply referred to as purification system) of the waste transfer station of this embodiment is designed for this type of waste transfer station.
The purification system monitors environmental parameters and equipment parameters of the waste transfer station through the monitoring unit 300. The environmental parameter includes a malodorous gas index. And the purifying system adjusts the equipment parameters according to the environmental parameters. When the monitoring unit 300 detects that the odor index exceeds the preset threshold, the microprocessor of the purification system makes a judgment, and invokes the devices of other units to process the odor. Such as the closing unit 100, for preventing the malodorous gas of the garbage transfer station from escaping to the outside of the station; the absorption unit 200 is used for absorbing malodorous gas of the garbage transfer station; a photolysis unit 400 for purifying malodorous gas and removing bacteria therefrom; and the negative pressure unit 500 is used for collecting malodorous gas inside and outside the garbage transfer station into the negative pressure ventilation pipeline.
The specific processing flow is as follows: when the monitoring unit 300 detects that the odor gas index exceeds a preset threshold, the sealing unit 100 is started to prevent the odor gas from escaping; then the absorption unit 200 starts to work to absorb malodorous gases in the air; then, the negative pressure unit 500 is started to collect the malodorous gas inside and outside the garbage transfer station into the negative pressure ventilation pipeline; the photolysis unit 400 provided in the ventilation duct starts to operate to purify the malodorous gas and remove bacteria therein; and finally, discharging the purified gas through an exhaust outlet.
In an experimental example, the treatment effect of the purification system is shown in the table above. Inlet air volume 7488m3Per hour, outlet air quantity 7718m3H is used as the reference value. The purification efficiency was calculated as follows:
purification efficiency ═ ((inlet concentration × -inlet air volume) - (outlet concentration × -outlet air volume))/(inlet concentration × -inlet air volume).
Wherein H2S purification efficiency ((0.019 × 7488) - (0.005 × 7718))/(0.019 × 7488) ═ (142.27-38.59)/142.27 ═ 72.88%;
NH3purification efficiency ((0.975 × 7488) - (0.303 × 7718))/(0.975 × 7488) ═ (7300.8-2338.55)/7300.8 ═ 67.28%;
VOCs purification efficiency ((6.83 × 7488) - (2.16 × 7718))/(6.83 × 7488) — (51143.04-16670.88)/51143.04 — 67.40%.
It is particularly noted that this is measured with a lower initial concentration, and the efficiency of the treatment is higher if the initial malodorous gas concentration is higher. In the results of this test, H in the treated gas can be seen2S、NH3And the content of VOCs is close to one third to one fourth of the original content, so that the content of malodorous gas in the garbage transfer station is greatly reduced, and the corresponding standards specified by the state are met.
