Description
IZGUDROJUMA APRAKSTS [001] Izgudrojums attiecas uz notekūdeņu siltuma rekuperācijas iekārtām, jo īpaši uz rekuperācijas iekārtām, kas izmantojamas sabiedrisko ēku, industriālo objektu apsildei un daudzdzīvokļu namu karstā ūdens apgādei.DESCRIPTION OF THE INVENTION The invention relates to waste water heat recovery units, in particular to heat recovery units for heating public buildings, industrial facilities and hot water supply in apartment buildings.
Zināmais tehnikas līmenis [002] Ir zināmas dažādas notekūdeņu rekuperācijas iekārtas. ASV patenta pieteikuma US4341263 publikācijā izklāstīts notekūdeņu siltummainis, kurā tiek novadīts ēkās izlietotais siltais ūdens, lai atgūtu šo silto notekūdeņu enerģiju un novadītu atkārtoti mājas sistēmā. Minētā iekārta izmanto speciālu siltuma pārneses šķidrumu, kas sarežģī gan pašu sistēmu, gan tās apkopi.PRIOR ART Various wastewater recovery units are known. U.S. Patent Application No. 4,341,263 discloses a wastewater heat exchanger that discharges warm water used in buildings to recover this warm wastewater energy and recycle it into the home system. The unit uses a special heat transfer fluid, which complicates both the system itself and its maintenance.
[003] Starptautiskā patenta pieteikuma WO0198714 publikācijā aprakstīta siltuma atgūšanas ierīce, kas iebūvēta notekas sifonā. Ierīce satur siltummaiņa cauruļu sistēmu, kas ir ievietota sistēmā un ar kuras palīdzību tiek noņemts siltums no ieplūstošiem siltajiem notekūdeņiem.[003] International patent application WO0198714 describes a heat recovery device embedded in a drain siphon. The device includes a heat exchanger pipe system that is embedded in the system and removes heat from the warm water flowing into the system.
[004] Lielbritānijas patenta pieteikuma Nr. 2304877 publikācijā aprakstīta ūdens apgādes sistēma ar siltuma atgūšanu, kur siltie notekūdeņi, pirms novadīšanas notekūdeņu sistēmā, tiek padoti uz siltummaini, kur siltums daļēji tiek noņemts un atdots atpakaļ sistēmai.[004] British patent application no. Publication 2304877 discloses a heat recovery water supply system, wherein the warm waste water, before being discharged into the waste water system, is fed to a heat exchanger where the heat is partially removed and returned to the system.
[005] Minētās sistēmas neparedz ilgstošu silto notekūdeņu uzturēšanu sistēmā, lai pēc iespējas efektīvāk noņemtu siltumu. Tas ir saistīts ar notekūdeņu bioloģisko aktivitāti, veidojot bioplēves un citus nosēdumus sistēmā. Attiecīgi minētās sistēmas ir sarežģītas to apkopē, jo prasa nepārtrauktu to uzraudzību.[005] These systems do not provide for the long-term maintenance of warm waste water in the system to remove heat as efficiently as possible. This is due to the biological activity of wastewater forming biofilms and other sediments in the system. Accordingly, these systems are complex to maintain as they require constant monitoring.
Izgudrojuma mērķis un būtība [006] Izgudrojuma mērķis ir uzlabot notekūdeņu siltuma rekuperācijas iekārtas efektivitāti, paaugstinot siltuma noņemšanas lietderības koeficientu, kā arī uzlabojot tās ekspluatāciju attiecībā uz apkopi.OBJECTIVE AND SUMMARY OF THE INVENTION The object of the invention is to improve the efficiency of a waste water heat recovery unit by increasing the efficiency of heat removal as well as improving its operation with respect to maintenance.
[007] Izgudrojuma mērķis tiek īstenots, izveidojot notekūdeņu siltuma rekuperācijas iekārtu, kas satur šādus galvenos elementus: silto notekūdeņu nostādināšanas tvertni, cieto daļiņu nostādināšanas tvertni, silto notekūdeņu pieplūdes cauruli, notekūdeņu novades cauruli, spiedkanalizācijas novades cauruli, notekūdeņu sūkni, kas ievietots cieto daļiņu nostādināšanas tvertnē, notekūdeņu uzskalošanas vārstu, siltummaiņa kontūru un siltumsūkni.The object of the present invention is achieved by providing a waste water heat recovery unit comprising the following main elements: a warm waste water settling tank, a solid particle settling tank, a warm waste water inlet pipe, a sewage drain pipe, a pressure sewer pipe, a sewage suction pump, a settling tank, a waste water flushing valve, a heat exchanger circuit and a heat pump.
[008] Silto notekūdeņu nostādināšanas tvertne ir viens no galvenajiem iekārtas elementiem, un minētā tvertne ir paredzēta silto notekūdeņu uzglabāšanai, lai efektīvi varētu noņemt tajā esošo notekūdeņu siltumu.[008] The warm wastewater settling tank is one of the main elements of the apparatus and said tank is intended for storing the warm wastewater in order to efficiently remove the heat from the wastewater therein.
[009] Notekūdeņu siltuma rekuperācijas iekārta papildus satur cieto daļiņu nostādināšanas tvertni, kas ir ievietota silto notekūdeņu nostādināšanas tvertnē, vēlams koncentriski, un ir savienota vai ir fluīda komunikācijā ar minēto silto notekūdeņu nostādināšanas tvertni caur cieto daļiņu nostādināšanas tvertnes augšpusē izvietotu cieto daļiņu nostādināšanas tvertnes pārplūdes kanālu vai T-gabalu. Fluīdu komunikācija izgudrojuma kontekstā ir tāds šķidrumu pārvadošs savienojuma veids, kas nodrošina šķidruma pārplūdi no viena vietas uz otru, piemēram, no vienas tvertnes uz otru tvertni. Fluīdu komunikāciju var nodrošināt, piemēram, ar cauruļu savienojumu palīdzību. Pie cieto daļiņu nostādināšanas tvertnes ir pievienota silto notekūdeņu pieplūdes caurule, caur kuru notekūdeņu rekuperācijas iekārtas cieto daļiņu nostādināšanas tvertnei tiek pievadīti siltie notekūdeņi. Savukārt tālāk šie siltie notekūdeņi caur cieto daļiņu nostādināšanas tvertnes pārplūdes kanālu vai T-gabalu nonāk silto notekūdeņu nostādināšanas tvertnē, no kuras tie savukārt tiek aizvadīti prom uz kanalizāciju no nostādināšanas tvertnes apakšējās daļas caur notekūdeņu novades cauruli, kas savienota ar silto notekūdeņu nostādināšanas tvertni. Cieto daļiņu nostādināšanas tvertnes pārplūdes kanāls vai T-gabals ir vienīgais elements, caur kuru siltie notekūdeņi no cieto daļiņu nostādināšanas tvertnes var nonākt silto notekūdeņu nostādināšanas tvertnē.The wastewater heat recovery unit further comprises a solid particle settling tank which is housed in a warm wastewater settling tank, preferably concentric, and is connected or in fluid communication with said warm wastewater settling tank via a solid particle settling tank top channel or T-piece. Fluid communication in the context of the invention is a type of fluid-carrying connection that allows fluid to flow from one location to another, for example, from one container to another. Fluid communication can be achieved, for example, by means of pipe connections. A warm wastewater inlet pipe is connected to the particulate settling tank through which the warm wastewater is fed to the particulate settling tank of the wastewater recovery unit. Further, these warm wastewater passes through the solid particle settling tank overflow channel or T-piece to the warm wastewater settling tank, from where they are discharged to the drain from the lower part of the settling tank via the sewage drainage pipe connected to the warm wastewater drainage pipe. The particulate settling tank overflow channel or T-piece is the only element through which the warm effluent from the particulate settling tank can enter the warm effluent settling tank.
[010] Turklāt notekūdeņu siltuma rekuperācijas iekārta papildus satur spiedkanalizācijas novades cauruli, kas savieno cieto daļiņu nostādināšanas tvertni ar notekūdeņu novades cauruli, lai cieto daļiņu nostādināšanas tvertnē esošos notekūdeņus novadītu uz notekūdeņu novades cauruli, kur savukārt tie tiek aizvadīti prom uz kanalizāciju. Spiedkanalizācijas novades caurules viens gals ir savienots ar notekūdeņu sūkni, bet otrs gals ir savienots ar minēto notekūdeņu novades cauruli. Minētais notekūdeņu sūknis ir paredzēts jeb pilda divas funkcijas. Pirmkārt, notekūdeņu sūknis uzsūc cieto daļiņu nostādināšanas tvertnē esošos notekūdeņus un caur spiedkanalizācijas novades cauruli nogādā notekūdeņus uz notekūdeņu novades cauruli. Otrkārt, notekūdeņu sūknis uzsūc cieto daļiņu nostādināšanas tvertnē esošos notekūdeņus un padod tos uz spiedkanalizācijas novades caurulē iebūvēto notekūdeņu uzskalošanas vārstu, no kurienes minētie notekūdeņi tiek izdoti uz cieto daļiņu nostādināšanas tvertnē izveidojošos cieto daļiņu slāni jeb virskārtu tās sašķelšanai. Turklāt notekūdeņu sūknis ir izvietots cieto daļiņu nostādināšanas tvertnes apakšējā daļā, vēlams pie minētās cieto daļiņu nostādināšanas tvertnes pamatnes, lai būtu pēc iespējas tālāk no bioplēves veidošanās zonas.In addition, the wastewater heat recovery unit further comprises a pressure sewer drainage pipe which connects the particulate settling tank to the wastewater drainage pipe to direct the wastewater from the particulate settling tank to the wastewater drainage pipe, which in turn is discharged to the sewer. One end of the pressure sewer pipe is connected to a sewage pump and the other end is connected to said sewage pipe. This wastewater pump has two functions. First, the wastewater pump absorbs the wastewater from the particulate settling tank and delivers the wastewater through the discharge pipe to the wastewater discharge pipe. Secondly, the wastewater pump absorbs the wastewater from the particulate settling tank and feeds it to a wastewater flush valve built into the pressure drainage pipe, from where the wastewater is discharged to the particulate settling tank to form a layer or layer thereof. Further, the sewage pump is located in the lower part of the particulate settling tank, preferably at the base of said particulate settling tank, to be as far away from the biofilm formation area as possible.
[Oil] Notekūdeņu uzskalošanas vārsts ir izvietots cieto daļiņu nostādināšanas tvertnes augšējā daļā virs notekūdeņu līmeņa, lai pie minētā notekūdeņu uzskalošanas vārsta atvēršanās tiktu izdota notekūdeņu strūkla, kas sašķeltu cieto daļiņu nostādināšanas tvertnē izveidojušos cieto daļiņu slāni. Minētais slānis galvenokārt veidojas cieto daļiņu nostādināšanas tvertnē esošo notekūdeņu līmenī. Šāda konstrukcija nodrošina efektīvu bioplēves sagraušanu, kas neizbēgami veidojas notekūdeņu klātbūtnes rezultātā. Attiecīgi tiek palielināts iekārtai nepieciešamais apkopes intervāls, samazinot ekspluatācijas izmaksas.[Oil] The wastewater flushing valve is located at the top of the particulate settling tank above the wastewater level so that, when said wastewater flushing valve opens, a jet of waste water is discharged to break up the particulate layer formed in the particulate settling tank. This layer is mainly formed at the level of wastewater in the particulate settling tank. Such a construction ensures effective destruction of the biofilm, which is inevitably formed by the presence of sewage. The maintenance interval required for the unit is accordingly increased, reducing operating costs.
[012] Notekūdeņu siltuma rekuperācijas iekārta satur siltummaiņa kontūru, kas ievietots notekūdeņu nostādināšanas tvertnē ap tajā esošo cieto daļiņu nostādināšanas tvertni siltuma noņemšanai no silto notekūdeņu nostādināšanas tvertnē esošajiem notekūdeņiem. Savukārt siltummaiņa kontūrs ir savienots ar siltumsūkni, tādejādi nodrošinot notekūdeņu siltuma rekuperāciju.[012] The waste water heat recovery unit comprises a heat exchanger circuit, which is placed in the waste water settling tank around the solid particle settling tank therein to remove heat from the waste water in the warm sewage settling tank. The heat exchanger circuit, on the other hand, is connected to the heat pump, thus ensuring waste heat recovery.
[013] Vienā no iekārtas risinājumiem siltummaiņa kontūrs cieto daļiņu nostādināšanas tvertnes ārējai virsmai ir izvietots tuvāk nekā silto notekūdeņu nostādināšanas tvertnes iekšējai virsmai, lai palielinātu siltuma noņemšanas efektivitāti arī no cieto daļiņu nostādināšanas tvertnē ieplūstošajiem notekūdeņiem. Citā risinājumā siltummaiņa kontūrs ir izvietojams tieši pie daļiņu nostādināšanas tvertnes ārējās virsmas, papildus uzlabojot siltuma noņemšanas efektivitāti. Siltummaiņa kontūrs ir izvietots ap cieto daļiņu nostādināšanas tvertnes ārsienu, vēlams spirālveidā.[013] In one embodiment of the device, the heat exchanger circuit is positioned closer to the outer surface of the particulate settling tank than to the inner surface of the warm wastewater settling tank to increase heat removal efficiency also from the effluent entering the particulate settling tank. Alternatively, the heat exchanger circuit can be positioned directly on the outside of the particle settling tank, further improving heat removal efficiency. The heat exchanger circuit is located around the outer wall of the particulate settling tank, preferably in a spiral shape.

Savukārt pie spiedkanalizācijas novades caurules (5) gala, kas atrodas cieto daļiņu nostādināšanas tvertnē (2), ir pievienots notekūdeņu sūknis (6). Turklāt notekūdeņu sūknis (2) ir izvietots cieto daļiņu nostādināšanas tvertnes (2) apakšējā daļā pie pašas cieto daļiņu nostādināšanas tvertnes (2) pamatnes. Turklāt notekūdeņu sūknis (6) ir savienots ar spiedkanalizācijas novades cauruli (5) tādā veidā, lai no notekūdeņu sūkņa (6) uzsūktos notekūdeņus nogādātu uz minēto notekūdeņu novades cauruli (4).[015] FIG. illustrates a wastewater heat recovery unit comprising a warm wastewater settling tank (1) and a concentrate particulate settling tank (2) housed therein. Said particulate settling tank (2) is in fluid communication with said warm sewage settling tank (1) through a particulate settling tank (2) overflow channel (22), such as a T-piece, located at the top of the particulate settling tank (2). The apparatus further comprises a warm wastewater inlet pipe (3) connected to the solid particle settling tank (2) and through which the warm wastewater is initially fed to the solid particle settling tank (2) of the wastewater recovery unit. The inlet to the warm waste water inlet pipe (3) is located at the top of the particulate settling tank (2). The apparatus further comprises a waste water discharge pipe (4) connected to a warm waste water storage tank (1) for discharging the waste water contained therein. In addition, the device comprises a pressure sewer drain pipe (5) which connects the solid particle settling tank (2) with the sewage drain pipe (4). In turn, a sewage pump (6) is connected to the end of the discharge pipe (5), which is located in the particulate settling tank (2).

[016] Minētā notekūdeņu siltuma rekuperācijas iekārta raksturīga ar to, ka papildus satur notekūdeņu uzskalošanas vārstu (8), kas savienots ar spiedkanalizācijas novades cauruli (5) apgabalā vai zonā, kas atrodas cieto daļiņu nostādināšanas tvertnes (2) augšējā daļā virs tajā esošo notekūdeņu līmeņa, kā rezultātā pie minētā notekūdeņu uzskalošanas vārsta (8) atvēršanās tiek izdota notekūdeņu strūkla, kas sašķeļ cieto daļiņu nostādināšanas tvertnē (2) izveidojušos cieto daļiņu slāni jeb virskārtu. Minētais slānis jeb virskārta veidojas cieto daļiņu nostādināšanas tvertnē (2) esošo notekūdeņu līmenī. Attiecīgi, šī bioslāņa jeb bioplēves sagraušana novērš nepieciešamību pēc pārāk biežas iekārtas apkopes, samazinot tās ekspluatācijas izdevumus. Iekārta papildus satur siltummaiņa kontūru (9), kas ievietots notekūdeņu nostādināšanas tvertnē (1) ap tajā esošo cieto daļiņu nostādināšanas tvertni (2) siltuma noņemšanai no silto notekūdeņu nostādināšanas tvertnē (1) esošajiem notekūdeņiem, un siltummaiņa kontūrs (9) ir savienots ar siltumsūkni (10).
