Sk lada si e ono z dwóch zbiorników (oko lo 1000 litrów), w których znajduje si e wezownica ze stali nierdzewnej o pojemno sci oko lo 20 litrów (mo ze by c wi ecej). Do w ezownicy wp lywa zimna woda z sieci miejskiej lub studni, która ogrzewa si e od temperatu- ry 9°C zim a 12°C latem do temperatury scieków to jest oko lo 30°C. Scieki z lazienki i kuchni nape lniaj a nieustannie zbiorniki nr 1 i 2, które dop lywaj a rurami izolo- wanymi. Najpierw nape lnia si e zbiornik nr 2 do wysoko sci 2/3 a pó zniej scieki przelewaj a si e do zbior- nika nr 1 przez rurk e z sitkiem. Po osi agni eciu maksymalnego poziomu ich nadmiar wylewa si e otwo- rem rury Z1 ze zbiornika nr 1 umieszczonym tu z przy dnie (tam temp. wody jest najni zsza). Najcieplej- sze warstwy scieków u góry zbiorników ogrzewaj a wod e w w ezownicy. W zbiorniku nr 2 równie z znajduje si e u samej góry otwór wyp lywowy, ale jego poziom jest wy z- szy o kilka mm (ok. 5mm) wzgl edem zbiornika nr 1. S lup wody z t luszczem b edzie zawsze wy zszy od s lupa samej wody przy naczyniach laczonych, poniewa z g estosc t luszczu jest mniejsza od g esto sci czystej wody. Tu z przy tym otworze powinny wp lywa c scieki domowe, aby ich ciep lo by lo obierane przez nagromadzony na powierzchni wody t luszcz, co u latwia jego wyp lyw. W izolowanej rurze odprowadzaj acej scieki domowe jest umieszczony elektryczny zawór, który automatycznie zamyka si e przy przep lywie zimnej wody i kieruje j a do kolektora polnego z WC. W celu opró znienia zanieczyszcze n znajduj acych si e w zbiorniku nr 2 nale zy raz na kilka mie- siecy (oko lo 6 miesi ecy) otworzy c go. Wtedy te z wyleje si e 1/3 scieków ze zbiornika nr 1. Uzupe lnienie zbiorników sciekami dokona si e w ci agu 1 - 2 dni. Oczywi scie, ze wtedy woda w wezownicy nie b edzie podgrzewana.

PL PLDesign description The device is used to recover thermal energy from domestic and hotel sewage, etc. It consists of two tanks (about 1000 liters) with a stainless steel coil with a capacity of about 20 liters (maybe more). The coil is fed with cold water from the municipal network or a well, which is heated from a temperature of 9 ° C in winter and 12 ° C in summer to the temperature of sewage, ie about 30 ° C. The sewage from the bathroom and the kitchen is constantly filled with tanks 1 and 2, which flow in with insulated pipes. First, the tank No. 2 is filled to a height of 2/3, and then the sewage overflows into the tank No. 1 through a pipe with a strainer. After reaching the maximum level, their excess is poured out through the hole in the Z1 pipe from the tank no. 1 located near the bottom (where the water temperature is the lowest). The warmest layers of sewage at the top of the tanks heat the water in a coil. In the tank No. 2 there is also an outflow opening at the very top, but its level is a few mm (approx. 5mm) higher than in the tank No. 1. The glass of water with oil will always be higher than the column the same amount of water with jointing vessels, as the total fat is less than that of pure water. Here, at this opening, domestic sewage should flow in so that its heat is removed by the fat accumulated on the surface of the water, which facilitates its discharge. An electric valve is placed in the insulated drainage pipe, which automatically closes when cold water flows and directs it to the field collector from the toilet. In order to empty the contaminants from the tank no. 2, open it once every few months (about 6 months). Then 1/3 of the sewage from reservoir no. 1 will also spill out. The reservoirs will be replenished with sewage within 1-2 days. Of course, then the water in the coil will not be heated. It is possible to use a valve with a timer, but it requires electrical installation. The essence of the device is that the sewage from the toilet is fluid and another parallel pipe, with which it connects the outlet pipes from the tanks No. 1 12. The tanks No. 1 and 2 are insulated on all sides, at a distance from Between them you can wear from 0 to a few cm: at the top they have lazes with lids. The heated water from the coil will be directed for further heating and term 1 flow heater) or to the washing machine or dishwasher as cold. In the future, when batteries with three inlets (cold, heat in a coil and hot from a thermal bath) will be produced, it will be possible to direct warm water to the kitchen and washbasin in lence, because then in the middle zone When the battery lever is turned, water (about 30 ° C) will flow without moving left or right. All you have to do is lift the levers and you will flow: without moving the levers for warm water, almost always the same warmth. Estimate of the device: - two plastic tanks with a capacity of about 1000 liters each are needed. They are used for the price of 150 PLN; - 60 m of stainless steel pipe, approx. 14 l / m (gross); - several dozen meters of insulated metal or plastic pipe at a price of 2-4 l / m of heated water supply to receivers; - several meters of sewage plastic pipe, also made of insulated (2-4 l / m); - solenoid valve (about PLN 170) - drain ball valve (PLN 70) - styrofoam 18 m2 for PLN 18 / m2) Cost without assembly 1300-1500 PLN. As a result of using my device, it is reduced that the consumption of electricity in some households even doubled, thus reducing the emission of exhaust gases from the atmosphere. Unemployment is decreasing, as services for new installations and modernization of old ones have developed, new jobs will be created in the production of component parts of devices (details). First of all, the expenditure on electricity is decreasing. A.PL 64 687 Y1 3 Calculations Assuming that we consume about 150 liters of warm water (shower, bathtub, washing machine, dishwasher, kitchen) in one family energy saved will be: - daily in one household E = c * m *? t (c- warm water in l right water, m-mass of water, increase in heated water temperature) E = 1 * 150 * (29-11 ) kcal (? t is about 18 dag because the temperature of flowing sewage is about 29 ° C and the temperature of water from a well or city network is on average 11 ° C) E = 4.19 * 1 * 150 * 18 [kJ ] E = 11313 [kJ] E = 11313 [kWh] 3600 E = 3.142 [kWh] - Annual: energy saved by one household E = 3.142 * 365 [kWh] E = 1146.83 [kWh] (i.e. approx. PLN 413 saved) - The energy saved in Poland will amount to E ˜ 9.18 * 10 9 [kWh] assuming that 8 million households will be used by the device. The amount of coal saved will be: m ˜ 9.18 * 10 9 * 3600 [kJ] = 9.18 * 3.6 * 10 12 [kg] = 1.03 * 10 9 [kg] (Cs-heat of combustion C) 3.2 * 10 4 [kJ / kg] 3.2 * 10 4 Cs ˜ 3.2 * 10 4 [kJ / kg] m ˜ 1 million tons The efficiency sc of the power plant is about 33%. Thus, the mass of unburnt coal after using the device : m ˜ 3 * 1 million [tonnes] m ˜ 3 million [tonnes] The amount of CO 2 not emitted to the atmosphere will be twice as much, ie about 6 million tonnes.
