Purify decomposing system 400, the gas given off for purifying the refuse transfer station;
Automatic control system 500, including monitoring modular, the monitoring modular is for monitoring refuse transfer station and nearby specifying Environmental data in range;
Automatic control system 500 prevents diffusion system 100, stench adsorption system according to the environmental data, respectively control 200, the operating condition of idle decontamination system 300, purification decomposing system 400.
In the present embodiment, include multiple small subsystems for the round-the-clock air cleaning system of refuse transfer station, it is main Diffusion system 100, stench adsorption system 200, idle decontamination system 300 are prevented, decomposing system 400 is purified, automatically controls System 500.Wherein, subsystem is divided by function two kinds, and one kind is sensing and control system, i.e. automatic control system 500;Separately One kind is execution system, including prevents diffusion system 100, stench adsorption system 200, idle decontamination system 300, purifies resolving system System 400.
Prevent diffusion system 100 from only working when domestic refuse shifts.Stench adsorption system 200, purification are decomposed System 400 then works when air quality is less than preset air quality index.Idle decontamination system 300 then is preventing from spreading System 100, stench adsorption system 200, purification decomposing system 400 be when working, to the standing air in refuse transfer station into One step purifies.500 all weather operations of automatic control system, monitors the environmental data of refuse transfer station, according to the environment monitored The operating condition of each execution system of data point reuse.
Optionally, stench adsorption system 200 includes high-pressure atomization host, deodorant stoste storage tank, high voltage precision pump, atomization Nozzle and the necessary pipeline connected for equipment room;
Deodorant after being pumped out by the high voltage precision, sprays after certain dilution through atomizer;
The high-pressure atomization host is used to adjust the power of the high voltage precision pump, and is connected with automatic control system 500 It connects.
In the present embodiment, stench adsorption system 200 controls foul gas source from source.Deodorant can be passed through advanced essence It is delivered to atomizer after close pump pressurization.Deodorant is fully atomized into fine droplet by atomizer.Deodorant drop uniformly mixes The storage point in refuse transfer station is closed, is then covered on rubbish.The foul smell molecule that deodorant drop comes out with rubbish It comes into full contact with, in small droplet surface there is great surface energy, the surface energy deodorant drop can be made in rubbish surface shape At one layer of liquid film.This layer of liquid film can adsorb distribute formed in air the ammonia of foul smell, hydrogen sulfide, trimethylamine, mercaptan, methanol, The foul smell molecule such as organic amine, it is suppressed that rubbish fermentation generates foul smell.Moreover, deodorant drop includes microbe composition, microorganism The foul smell molecular oxidation of absorption can be resolved into odorless inorganic salts, be finally reached and foul smell is inhibited to generate and purify stench Effect.Such deodorant can bought on the market.
Stench adsorption system 200 further includes PLC controller, and PLC controller is connect with automatic control system 500, by automatic Control system 500 sends out control signal, the working condition of control stench adsorption system 200.PLC controller transmits a signal to high pressure Deodorant is extracted from deodorant stoste storage tank, after being diluted to dilution, is flowed to through pipeline by precision pump, high voltage precision pump Atomizer, atomization spray.PLC controller can be arranged sprayed m seconds at interval of n minutes.It can be adjusted according to different input signals Spray intervals.Such as increase to high voltage precision pump stream time m+a seconds, the interval time of work is reduced to n-b minutes.
Optionally, it includes air curtain to prevent diffusion system 100, and the air curtain is connected with the automatic control system 500 It connects.
In the present embodiment, prevent diffusion system 100 for ensureing that the exhaust gas in refuse transfer station is not excessive.Prevent diffusion system System 100 includes using the air curtain that polluted gas is exchanged with outdoor air in barrier refuse transfer station.Air curtain may be mounted at Refuse transfer station passes in and out above rubbish doorway.The air curtain noise of selection is not more than 65dB.
In order to ensure remaining a small amount of foul gas in refuse transfer station is not excessive, it is necessary to ensure in refuse transfer station Tiny structure, i.e. the pressure difference in exit should be not less than 10Pa.To ensure that exit is not less than 10Pa, air-flow velocity v need to be not less than 0.85m/s.However, the outlet size of conventional rubbish transfer station is bigger, calculated with the refuse transfer station of the B grades of simple gate, Its width be 5.5m, high 5.0m, capacity reach 84170m3/h.And many refuse transfer stations are two door designs.By the above result of calculation It is found that according to negative pressure system, refuse transfer station needs tens of thousands of or even ten tens of thousands of capacities.Obviously, this can consume a large amount of energy Power is not realistic.Therefore air quantity must be reduced on the basis of ensuring the tiny structure in refuse transfer station.However, drop Low air quantity needs to close refuse depot, but closing refuse depot gate can influence the normal operation of refuse depot.Therefore, this implementation Example is closed using air curtain, blocking foul gas dissipation.
With reference to Fig. 2, Fig. 2, which is round-the-clock air cleaning system one embodiment of the present invention for refuse transfer station, to be prevented from spreading The working state schematic representation of system.
