Description

  The present invention relates to a vehicle-mounted medicine spraying system that can remove malodors by spraying chemicals against malodors that occur during the collection of garbage, and a garbage collection vehicle that includes the chemical spraying system.

  Various garbage such as raw garbage generated from households and business establishments is collected by garbage collection vehicles by local governments, and in many cases is incinerated. Garbage is collected and compressed by a garbage truck (packer car) at the time of collection, and the volume is reduced and transported to an incinerator. Garbage trucks have various types of compression mechanisms for volume reduction, but when they are compressed, garbage bags are torn and odors are leaked to the outside, and substances that emit odors such as sewage are collected in garbage collection. There are many cases where it becomes a factor that causes trouble for the collection workers and local residents, such as the garbage truck itself adhering to the car body and giving off odor.

In order to cope with such a problem, a deodorizing apparatus that is installed in a garbage truck and sprays a deodorizing liquid has been proposed (Patent Document 1). However, when the odor from the malodorous substances attached to the garbage truck is not enough to remove the odor generated from the garbage truck, the garbage input door of the garbage truck opens. It was a problem such as odor diffusion.

  Leakage of bad odor to the outside of the garbage truck can be effectively suppressed, and the work environment can be improved and odor pollution can be reduced.

  Embodiments of the present invention will be specifically described below with reference to the drawings. Garbage trucks are equipped with various types of garbage compression and volume reduction mechanisms, including rotary plate type, compression plate type, packing box rotary type, and rotary press type. 1-4, a rotary plate compression type garbage truck is taken as an example. However, the drug spray system of the present invention is not limited to being mounted on a compression mechanism type garbage truck, and a garbage input door is provided. Any garbage truck that is installed is a garbage collection vehicle that opens when the garbage is collected to create an opening that serves as a garbage entry port. Is also applicable.

  FIG. 4 is a side view (1) and a rear view (2) of a normal garbage truck. Garbage collection is generally performed by a garbage collection vehicle provided with a garbage storage unit 12 in the garbage collection vehicle main body 11, and the garbage collection vehicle has a garbage input unit sealing door 13 that is closed except during garbage collection. There is a garbage storage part that is put into the garbage input part 15 from the garbage input port 14 that can be formed as an opening by opening the dust input part sealing door at the time of collection and is compressed and reduced by a mechanical compressor in the garbage input part. 12 is stored.

  When collecting garbage, the garbage bag is torn and the smell of garbage is diffused when the garbage is compressed. At this time, in many cases, the contents of the trash generating bad odors adhere to the inside of the trash input part and give off odor. The collected garbage is stored in the garbage storage section in the garbage truck, but the amount of odor generated from the garbage storage section increases as the amount of stored garbage increases. At the start of garbage collection, it is necessary to open the dust inlet sealing door and make an opening before putting in the garbage. At this time, the odor filled in the dust storage part and the garbage inlet leaks to the outside. The present invention pays attention to this point, and sprays chemicals into the dust input space when the dust input portion closed door is closed, thereby deodorizing and reducing odor diffusion to the outside.

  FIG. 1 is a side view (1), an XY cross-sectional view (2), and a rear view (3) of an example of a garbage truck equipped with the medicine spray system of the present invention. The medicine spraying system includes a medicine tank 21, a medicine supply pump 22, a medicine supply pipe 23, a dust inlet spray nozzle 24, and a spray control device 25 installed in the garbage truck main body. The operation of the spraying system is to discharge the drug introduced from the drug tank 21 by the drug supply pump 22 and to discharge the dust into the drug input part space through the drug supply pipe 23 from the drug spray nozzle 24 installed. Sprayed into the space.

  By spraying a chemical such as a deodorant toward the bad odor when the dust charging unit sealed door is closed, the spray system can greatly reduce the spread of bad odor to the outside when the dust charging unit sealed door is opened. . In addition, this spraying has an effect of preliminarily attaching a chemical such as a deodorant to the inner wall or compression plate of the dust input part before the dust is input, and also has an effect of suppressing the generation of odor.

  The spray nozzle in the dust input part can be installed anywhere as long as it can be sprayed into the space in the dust input part. However, it is easy to collect dust, diffusibility of chemicals, and difficult to clog the nozzle. In view of the above, it is preferable to install at the upper position of the dust inlet. The number of nozzles can be selected depending on the flow rate of the nozzles to be installed, the spray pattern, the cover range, and the size of the dust input space. One or more nozzles may be installed. It is preferable that the nozzle type and the number of nozzles can cover the entire surface of the dust inlet.

  In addition to spraying when the closed door is closed, the spraying of chemicals is also performed at the time of putting in the dust, that is, at the time of opening the dust input door. The odor effect can be enhanced. As the spray nozzle for spraying when the dust door is opened, the dust nozzle 24 may be used.

  Spraying in the dust input part can be controlled by a medicine spraying device. For example, a manual ON / OFF switch can be incorporated to manually turn on / off the spray when the odor is strong. It is possible to provide a spray control timer so that the spray control timer is turned off after a preset time has elapsed, or intermittent spray control can be performed at the time set in the timer. In addition, there is also a control to automatically open / close with a preset timer control after the set time elapses after the dust input unit sealing door is closed by providing an open / close detection sensor or open / close detection switch for the dust input unit sealing door. Is possible.

  2 is a side view (1), an XY cross-sectional view (2), and a rear view of another example of a garbage truck equipped with a medicine spraying system incorporating a deodorizing system for a dust storage unit in addition to the configuration of FIG. It is figure (3). It is possible to further reduce the leakage of odors to the outside by deodorizing the odors generated in the garbage storage part.

  Air (odor) in the dust storage unit is sucked by the air circulation blower 31 through the suction pipe 33 from the suction port 32 provided in the dust storage unit, and circulates from the return port 34 to the dust storage unit through the return pipe 35. Is done. A blower spray nozzle 36 capable of spraying into the pipe in the return pipe is provided so that the medicine can be sprayed into the pipe. Thereby, the medicine sprayed in the blower return pipe is supplied to the dust storage unit, and deodorization in the dust storage unit becomes possible. By circulating the air in the waste storage part, the entire waste storage part can be deodorized widely, and by spraying the medicine in the return pipe, the contact efficiency between bad odor and medicine is increased and the deodorization efficiency is increased, and the amount of medicine is smaller. The deodorizing effect can be obtained.

  Control of the medicine spraying system in the garbage storage unit can be performed by the spray control device 3a. For example, a manual ON / OFF switch can be incorporated to manually turn on / off the spray when the odor is strong. The operation at this time may be controlled so that the air circulation blower operation, the medicine supply pump operation, and the opening / closing of the blower spray valve 37 are interlocked when the ON / OFF switch is turned ON. In a system that performs both spraying in the dust input unit and spraying in the dust storage unit, if a dust input unit spray valve 38 is provided and controlled to open and close in conjunction with the operation of the drug supply pump during spraying in the dust input unit, Good. In the timer control, it can be used by being incorporated in the spray control device in the same manner as in the embodiment of FIG.

  The installation position of the blower exhaust spray nozzle is preferably installed near the return port 34 so as not to flow backward in the blower piping. The number of nozzles is not particularly limited, and may be one or a plurality. It is preferable to install a filter at the suction port and the return port to prevent suction and mixing of dust. For the filter, a hydrophobic filter such as a nonwoven fabric or a metal wire mesh such as stainless steel can be suitably used. These filters may have a double structure from the viewpoint of preventing clogging and facilitating maintenance.

  A sensor 39 for detecting an odor capable of external output is provided in either or both of the dust storage part and the dust input part, and when the sensor value exceeds a predetermined set value, the medicine is automatically sprayed in the sensor installation space. You can also The type of sensor can be selected depending on the type of garbage to be collected, and a semiconductor odor sensor, a concentration measuring device such as ammonia gas or hydrogen sulfide gas, and the like can be suitably used. At this time, the sensor output value can be taken into the medicine spray control device 3a, and when the sensor output value is equal to or higher than a reference value arbitrarily set in advance as the odor intensity, the spray valves 37 and 38 corresponding to the respective sensor positions are opened. It is sufficient to incorporate a mechanism that turns on the spray.

  It is also possible to use a combination of the above-described odor detection sensor control and timer control. For example, it is possible to control such that the spraying of the medicine is started when the output value of the odor detection sensor becomes equal to or higher than a preset reference value, and the spraying is stopped after the medicine is sprayed for a preset time. .

  As described above, by deodorizing the garbage input part and the garbage storage part, the garbage storage part of the garbage truck can deodorize and suppress the generation of bad odors, and achieve the deodorization during garbage collection. Leakage of bad odors that occur in general can be greatly reduced.

  FIG. 3 is a side view (1) and an XY cross-sectional view of an example of a garbage truck equipped with a medicine spraying system incorporating a medicine spraying system outside the garbage truck in addition to the forms of FIGS. 1 and 2. (2) and back view (3). In addition to the spray system of FIGS. 1 and 2, an exterior spray pipe 42, an exterior spray nozzle 41, and an exterior spray valve 43 are arranged. A flexible pipe or a hose that is easy to handle can be used for the outside spray pipe 42, and a mechanism capable of expanding and contracting the line, such as a hose winding type, may be installed. The length can be freely set as required. As the spray nozzle outside the vehicle, a nozzle that is generally used for agriculture or the like that can adjust a spray amount, a spray angle, and the like, a spray basket, and the like can be applied.

  Spray control of the spray nozzle outside the vehicle may be performed manually by opening and closing the spray valve provided outside the spray nozzle, and it can be turned on and off by providing a switch that can control the opening and closing of the drug supply pump and the spray valve outside the vehicle. Also good. At this time, if the pump and the valve can be opened and closed simultaneously in conjunction with each other, the number of switches can be reduced to one, which is more preferable in terms of workability and prevention of erroneous operation. The installation position of the spray nozzle outside the vehicle can be set anywhere in the garbage truck body in consideration of workability. There is no limit to the number of spray nozzles installed.

  By installing the spray nozzle outside the car, odors such as around the garbage inlet that cannot be covered by the spray nozzle in the garbage storage part and garbage input part, the outer periphery of the garbage truck, and further, for example, garbage storage are generated. Deodorizing agents and the like can be sprayed and deodorized at any location outside the garbage truck where the odor is expected.

  As the medicine that can be used, a medicine that can reduce malodor by coming into contact with malodorous substances generated from garbage can be used. Malodorous substances generated from garbage are representative of amines such as trimethylamine, nitrogen compounds such as ammonia, sulfur compounds such as methyl mercaptan and hydrogen sulfide, and organic acids such as isovaleric acid, although depending on the type of garbage. In addition, various malodorous substances are mixedly contained as miscellaneous odors. Therefore, known natural deodorants and chemical deodorants can be used as deodorizers that can decompose and remove the above-mentioned odorous substances and can also mitigate the odor.

  Examples of natural deodorants include wood vinegar, green tea and cypress extracts, plant extracts such as conifers and soybeans, soybean oil derivatives, plant extracts containing flavonoids and terpenes, essential oils, and the like.

  Chemical deodorants include aldehyde compounds such as formaldehyde, glyoxal, glutaraldehyde, malonaldehyde, benzaldehyde, succinaldehyde, and malealdehyde, oxocarboxylic acids such as glyoxylic acid and pyruvic acid, oxalic acid, citric acid, and malonic acid , Succinic acid, glutaric acid, adipic acid, pimelic acid, fumaric acid, methyl malic acid, isocitric acid, tartaric acid, gluconic acid, maleic acid, methyl maleic acid, methyl fumaric acid, itaconic acid, acetylenic acid, malic acid, formic acid, acetic acid , Lauric acid, linoleic acid, oleic acid, acrylic acid, polyacrylic acid, hydroxyacetic acid, sorbic acid, lactic acid, alginic acid, aspartic acid, glycine and other aliphatic carboxylic acids, benzoic acid, nicotinic acid, gallic acid, abietic acid , Cinnamic acid, fu Aromatic carboxylic acids such as phosphoric acid, terephthalic acid, trimellitic acid, and halogen-substituted esters of these organic acid compounds, alkali metal salt compounds and acid anhydrides, methacrylic acid esters such as lauryl methacrylate, and maleic acid such as dimethyl maleate Unsaturated ester compounds such as esters, organic nitrogen compounds such as monoethanolamine, diethanolamine, and triethanolamine, and salts thereof, inorganic alkalis such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, calcium carbonate, Inorganic acids such as sulfuric acid, phosphoric acid and hydrochloric acid, iron compounds such as divalent iron, manganese compounds such as potassium permanganate and manganese dioxide, titanium oxide, zirconium oxide, silicon oxide, calcium oxide, aluminum oxide, alum, Aluminum sulfate Umum, copper sulfate, zinc carbonate, zinc sulfate, zinc chloride, nickel, tin, lead, cobalt, platinum, palladium, silver, molybdenum, ruthenium, strontium and other metal compounds, hypochlorous acid, sodium hypochlorite, chlorine Acid salt, chlorite, chlorine dioxide, chlorine, salicin powder, chlorine compounds such as chlorinated isocyanuric acid, peroxides such as hydrogen peroxide, sodium percarbonate, calcium peroxide, ozone, hydrogen, hydrogen perboron Compounds, aluminum hydroxide compounds, sodium sulfite, sodium nitrate, sodium nitrite, hydrogen iodide, hydrazine and other redox agents, ethylene oxide, propylene oxide, butylene oxide and other epoxide compounds, cyclodextrins and other dextrin compounds, lauryl dimethyl Betaine compounds such as aminoacetic acid betaine, benzal chloride Substances such as cationic surfactants such as luconium and benzethonium chloride, amphoteric surfactants such as betaine type and glycine type surfactants, surfactants such as anionic surfactants and nonionic surfactants can be widely used. .

  These may be used alone or as a mixture of a plurality of substances. In particular, a deodorant containing an organic acid and an organic acid salt is more preferable in terms of a wide range of deodorizing effects, safety, and handleability, and glyoxylic acid, virpinic acid and the like are more preferable. Adding an aromatic component such as essential oil to the deodorant is effective in that it can functionally remove malodorous substances that cannot be completely removed.

  In order to enhance the deodorizing effect by the neutralization reaction, those containing a pH adjusting agent can also be suitably used. For acidic odors such as hydrogen sulfide and organic acid odors, neutral to alkaline deodorants are effective. For alkaline odors such as amine and ammonia, acidic deodorants are effective. The pH adjustment range can be set according to the acid alkalinity of the target malodorous substance, preferably in the range of pH 3.0 to 10.0, and in the range of pH 6.0 to 9.0 in terms of use environment such as corrosivity and handleability. More preferred. As the pH adjuster that can be used, any deodorizing component described above can be used as long as it dissolves in water and exhibits acidity and alkalinity. Malic acid, potassium hydrogen malate, malic acid, which are designated as food additives, can also be used. Sodium tartaric acid, sodium tartrate, potassium hydrogen tartrate, sodium tartrate, calcium tartrate, potassium bitartrate, adipic acid, ammonium adipate, potassium adipate, sodium adipate, ammonia water, potassium alum, carnauba wax, carnauba wax, citric acid, Calcium citrate, trisodium citrate, glucono delta lactone, gluconolactone, sodium gluconate, magnesium gluconate, succinic acid, monosodium succinate, disodium succinate, soda ash, fumaric acid, potassium fumarate, fumar Calcium phosphate, sodium fumarate, monosodium fumarate, Brazil wax, alum, phosphoric acid, magnesium phosphate, monopotassium phosphate, monosodium phosphate, diammonium hydrogen phosphate, dipotassium hydrogen phosphate, hydrogen phosphate Disodium, diammonium phosphate, dipotassium phosphate, disodium phosphate, potassium dihydrogen phosphate, sodium dihydrogen phosphate, ammonium bicarbonate, sodium bicarbonate, heavy carbon soda, calcined alum, ammonium acetate, calcium acetate , Sodium acetate, ammonium carbonate, potassium carbonate, carbon dioxide, sodium carbonate, ammonium bicarbonate, sodium bicarbonate, carbon soda, lactic acid, ammonium lactate, sodium lactate, potassium aluminum sulfate, adipic acid, itaconic acid, glycine, repose Sodium, sodium hydroxide, potassium hydroxide and the like can be more suitably used.

  The drug that can be used can be diluted with water according to the amount of malodor generated. The dilution factor depends on the spray amount and the size of the drug tank, but is preferably 1 to 100 times. When highly diluted, the deodorant component decreases, so it is more preferable to use 1 to 10 times diluted. Although there is no restriction | limiting in particular in the water which can be used for dilution, It is more preferable from a safety | security point that it is water utilized as drinking water, such as a tap water and a well water.

  In any of the above cases, the spray amount of the drug depends on the amount of dust, the type and generation amount of malodor, the deodorizing effect of the applied drug, the dilution factor used, etc. The amount of the spray liquid is preferably 0.01 to 5 L / min in the case of an in-vehicle spray nozzle, and more preferably 0.01 to 0.5 mL / min in terms of reducing the frequency of drug replenishment. In the case of an outside spray nozzle, it is preferably 0.1 to 10 L / min.

  As the drug pump of the spray system, a diaphragm pump, a vortex pump, a gear pump, a dynamic jet pump, or the like can be used. These pump capacities (flow rate, discharge pressure, etc.) may be determined according to the nozzle to be used. It is preferable that about 5-100L of chemical | medical agent tanks are installed according to the usage-amount and installation space of a chemical | medical agent. For the piping line, metal piping such as stainless steel, resin piping such as nylon, urethane and vinyl chloride, hoses and the like can be applied.

  As the spray nozzle of the spray system, a commercially available spray nozzle can be used without any particular limitation, but it is possible to spray with a spray particle size of less than 1 mm, and to select a nozzle orifice that is as large as possible in order to suppress nozzle clogging, maintenance frequency Is preferable in that it can be reduced. A two-fluid spray nozzle may be used as the spray nozzle. The two-fluid spray is a spray system that obtains a finer spray by mixing two fluids of the drug and compressed air and releasing it from the spray nozzle. The drug can be uniformly dispersed in the spray space. This is effective in that the deodorizing range can be expanded and the deodorizing effect can be enhanced. You may utilize the compressed air tank used for air brakes for the compressed fluid of 2 fluid spray. Thereby, it is not necessary to install a new compressor or compressed air tank, and the spray system can be made compact.

  In addition to the equipment shown in the figure, the spray system includes a flow meter, a pressure gauge, a pressure control valve, etc. for adjusting the spray amount as required, a check valve for maintenance of piping and nozzles, and a back pressure valve. It is effective to equip various piping parts such as a relief valve, a chemical filter for reducing nozzle clogging, and an air filter.

  The chemical spray system can also be applied to deodorize wastewater. Garbage drainage generated during the compaction of garbage is received by a drainage receptacle at the lower part of the garbage truck and stored in a sewage tank inside the garbage truck. When the chemical to be sprayed is mixed with the waste water, in addition to the effect of decomposing and removing malodors in the waste water, a deodorizing effect that suppresses the generation of malodors is also exhibited.

  If a chemical spray system is applied, the cleaning effect can be used in addition to the deodorizing effect of the chemical. In particular, when a chemical contained in a surfactant is used, in addition to the purpose of deodorization, a so-called cleaning effect such as an effect of suppressing the adhesion of dust and an effect of washing away the dust is manifested when the chemical comes into contact with the dust input part. The cleaning effect can also be used for other uses of garbage trucks. For example, a garbage collection vehicle can be washed by using an outside spray system as a car wash device for the garbage collection vehicle. In addition, it can be used as a window washer having a deodorizing function by connecting a medicine supply pipe to a window washer liquid line installed in the vehicle. At this time, if the liquid supplied to the window washer is equipped with a mechanism that can supply the liquid and the medicine of the present invention by switching, it can be used as the window washer liquid when the smell around the garbage truck is strong. By doing so, it can also be said that the deodorizing effect around the garbage truck is obtained simultaneously with the glass cleaning effect.

  The present invention will be described below based on examples, but the present invention is not limited to these specific embodiments. The preconditions of the embodiment are as follows.

  Install a chemical tank (10L), a chemical supply pump (diaphragm type) and a spray nozzle (three) in the trash input section in the trash input section in a general trash collection vehicle (maximum loading capacity 2 tons), In addition, an intake / exhaust pipe was attached to the dust storage part, connected to a vacuum blower, and a blower spray nozzle (one piece) was installed on the exhaust side of the blower. The drug supply pump and the spray nozzle were connected by a blade hose, and a solenoid valve was installed in the line as a dust input spray valve and a blower spray valve for each spray line. Control of opening and closing of the medicine supply pump, blower, and solenoid valve was performed by a control device (an electric control panel with a built-in spray control mechanism such as an ON / OFF switch and a timer). A commercially available deodorant (trade name: Schutter SR250FS, manufactured by Asahi Kasei Clean Chemical Co., Ltd.) in which an organic acid salt and a surfactant were blended in the drug was used by diluting 5 times with tap water. In addition, malodor was measured by sensory evaluation based on olfaction.

  When the garbage input door is closed before garbage collection work, the manual switch is turned ON and the spray nozzle in the dust input section and the blower spray nozzle are used to spray the liquid at a flow rate of 250 mL / min for 1 minute and then automatically stop with a timer. And sprayed. As a result, the bad odor when the garbage entry door was opened was reduced as compared with the case where no spraying was performed.

  In addition, at the opening of the dust at the time of the garbage collection operation, the manual switch was turned on to spray the medicine into the dust input part at a spray liquid amount of 250 mL / min for about 2 minutes. As a result, the bad odor was greatly reduced as compared with the case of no spraying. From the above, it can be seen that the chemical spray system of the present invention is effective for deodorizing malodors.
