ものである。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an incineration treatment device for waste liquid containing oil and solids discharged from factories, etc., and is used in incineration facilities for municipal waste, etc. It is used in a variety of ways.
（従来の技術）
工場等の産業用施設からは、数百PPM程度の
極く僅かな油分と固形異物を含んだ廃水から、水

で、種々雑多な廃液体が多量に排出されてくる。
これ等廃液体は、公害対策上そのまま廃棄するこ
とは出来ず、通常は廃棄物処理施設等で焼却処理
されている。(Conventional technology) Wastewater from industrial facilities such as factories ranges from wastewater containing a very small amount of oil and solid foreign matter of several hundred ppm to waste oil and waste solvent with a water content of about 10 to 90%. , a large amount of various miscellaneous waste liquids are discharged.
These waste liquids cannot be disposed of as they are due to pollution prevention measures, and are usually incinerated at a waste treatment facility.

市ごみ等と一緒に焼却処理できるようにするの
が、運転経済上最も理想的な形態である。 Therefore, when incinerating the waste liquid, there are various problems in terms of the economic efficiency of the device when using an incineration treatment device exclusively for the waste liquid, and it is difficult to incinerate it together with municipal waste, etc. The most ideal form from an operational economic point of view is to enable processing.
更に、廃液体を焼却処理するに際しては、より
少ない消費エネルギーでもつて廃液体を均一且つ
微細な粒径の噴霧に能率よく微粒化することが、
省エネルギーと安定した燃焼若しくは蒸発を達成
する上で必須の要件となる。 Furthermore, when incinerating waste liquid, it is important to efficiently atomize the waste liquid into a spray with uniform and fine particle size while consuming less energy.
This is an essential requirement for achieving energy conservation and stable combustion or evaporation.
しかし乍ら、従前のこの種廃液体の焼却処理装

因して、その殆んどが廃液体専用の焼却処理装置
となつており、都市ごみ等の固形廃棄物と廃液体
とを同時に機能的に焼却処理し得る実用的な焼却
処理設備は、未だ実用に供されていない。 However, due to the difficulty of achieving stable combustion in conventional incineration processing equipment for this type of waste liquid, most of them are incineration processing equipment exclusively for waste liquid, and are used only for municipal waste. Practical incineration equipment capable of functionally incinerating solid waste and waste liquid at the same time has not yet been put into practical use.
又、前記廃液体の焼却処理に於いては、第７図

蒸気補助圧力噴霧式ノズル、圧縮空気を噴霧作動
気体とする空気噴霧式ノズル等を利用して、廃液
体を微粒化する方法が採られている。 In addition, in the incineration process of the waste liquid, a steam atomizing nozzle that uses steam as a spraying gas as shown in FIGS. 7 and 8, or a steam atomizing nozzle as shown in FIG. Methods have been adopted to atomize waste liquid using steam-assisted pressure atomizing nozzles that use compressed air as the atomizing working gas, air atomizing nozzles that use compressed air as the atomizing working gas, and the like.
しかし、前記蒸気噴霧式ノズルの場合には、廃
液体量の30〜40％に相当する多量の噴霧用蒸気を

微粒化が達成出来ないという問題がある。また、

度でよく、前記蒸気噴霧式ノズルに比較して所要
蒸気量は相当減少するが、廃液体の噴霧圧力を20
Kg／cm2以上の高圧にする必要がある。 However, in the case of the steam atomizing nozzle, a large amount of atomizing steam equivalent to 30 to 40% of the amount of waste liquid is required, and it is said that sufficient atomization with a fine particle size cannot be achieved. There's a problem. Also,
In the case of a steam auxiliary pressure spray nozzle that uses steam as an auxiliary, the amount of steam used may be about 10% of the amount of waste liquid, and the required amount of steam is considerably reduced compared to the steam atomization nozzle. , waste liquid atomization pressure 20
It is necessary to use a high pressure of Kg/cm 2 or more.
ところが、廃液体中には通常様々な固形異物が

エネルギーの点に問題があるだけでなく、微粒化
の程度も不十分であり、十分満足すべき噴霧体が
得られないという問題がある。 However, waste liquid usually contains various solid foreign substances, and complete removal of these solid foreign substances is technically and cost-effective, so special treatment for removing solid foreign substances is rarely performed. It is never done. As a result, the solid foreign matter contained in the waste liquid not only causes severe wear on the pump, nozzle, etc., but also significantly increases the capacity and power consumption of the pump drive motor due to the high pressure. In this way, atomization using steam-assisted pressure atomization nozzles not only has problems in terms of wear and energy consumption, but also the degree of atomization is insufficient, making it impossible to obtain a fully satisfactory atomized body. There's a problem.
更に、空気噴霧式ノズルの場合にも、廃液体量
の15％〜40％に相当する多量の空気量を必要とす

という問題がある。 Furthermore, even in the case of an air atomizing nozzle, there is a problem in that sufficient atomization cannot be obtained although a large amount of air corresponding to 15% to 40% of the amount of waste liquid is required.

いという問題がある。 In addition to the above-mentioned problems, steam atomization nozzles, steam auxiliary pressure atomization nozzles, and air atomization nozzles are two-fluid nozzles (multi-hole nozzles), which complicates the nozzle structure, and the high atomization pressure It is necessary to make the nozzle diameter smaller, and as a result, there is a problem that blockage is likely to occur due to solid foreign matter in the waste liquid.

る。(Effect of the invention) In the present invention, the waste liquid to be treated is appropriately divided according to the ratio of oil to water, and the low-moisture waste liquid with a high oil content is atomized and sent to the waste incinerator 1 and the reburning furnace. 6
In addition, the high moisture waste liquid with low oil content is atomized and heated and evaporated in the waste liquid evaporation furnace 5 by the exhaust gas J from the garbage incinerator 1, and then completely combusted in the reburning furnace 6. The structure is such that each waste liquid is burned and heated using recovered waste heat, so low-moisture waste liquids are stored in the waste incinerator together with municipal waste, and high-moisture waste liquids are sent to the reburning furnace after evaporation. In addition to being incinerated in a stable state, it is also possible to significantly save energy by utilizing waste heat, making it possible to incinerate municipal waste and waste liquid more economically.

の防止を図ることが出来る。 Furthermore, the waste liquid spraying device used in the present invention is
Since this method focuses on the moisture contained in waste liquid and utilizes the boiling atomization phenomenon by heating, pressurizing, and then rapidly reducing the pressure, it requires a spraying gas such as steam, unlike previous spraying devices. In addition to making it possible to significantly reduce running costs, even if the spray pressure of waste liquid is as low as 1 kg/ cm2 , it is possible to produce extremely uniform and fine atomized particles by utilizing the boiling atomization phenomenon. This makes it possible to downsize the pump drive motor and prevent damage and clogging of the nozzle.
