Abstract
Provided is an on-line self-cleaning heat transfer enhancement sewage source heat pump system. A mechanical grid, a hair filter and the like are used for filtering sewage impurities, and sewage after filtering and solid particles separated through a solid-liquid separator together enter a sewage heat exchanger to be subjected to heat exchange. Meanwhile, four sewage pipes which are connected with the sewage heat exchanger are provided with a control valve b, a control valve c, a control valve d and a control valve e respectively, and the sewage pipes are back-flushed by controlling switching of a valve switch. The problems that in the process that the sewage is used as a cold and heat source, sewage impurities plug pipelines, hair plugs heat exchange equipment, the size of the heat exchange equipment is large due to dirt, and performance reduction and breakdowns happen to the heat exchange equipment due to mixed water are completely solved. The heat exchange performance of the system is greatly improved, safety, reliability and stability of the system are guaranteed, the sewage or surface water can be used as a low cold and heat source for conducting cooling supply and heating supply or cooling industrial equipment through a heat pump technology, and high efficiency and environmental protection are achieved.
Description
Technical field
The invention belongs to sewage heat change system, relate to a kind of sewage source heat pump system of online self-cleaning enhanced heat exchange.
Background technology
The utilization of sewage cold-hot source, can alleviate current energy-intensive situation, have good energy-saving effect, environmental benefit and economic benefit, will save freshwater resources day by day in short supply, for new field is opened up in using energy source, for comprehensive full use water resource provides a new thinking.Why sewage cold-hot source does not have large area to use with promoting is mainly because its water quality can not meet desired water standard in current water circulation system, in the middle of the engineering of actual motion, these dirts stop up water pump and heat exchanger often, cause systematic function obviously to decline, even can not move.
For addressing the above problem, take up an area the few filtering surface waterpower cyclic regeneration filter method of scalp and become the Perfected process that sewage cold-hot source utilizes, the main patent of filtering surface regeneration at present has ZL200410043654.9, ZL200720127607.1 and ZL200420031799.2 etc., its thinking is that scrubbing filtering surface (orifice plate filtering surface or orifice plate cartridge filter) is divided into filtering area and renewing zone two parts, utilize the water having filtered after participation heat exchange to carry out backwash to scrubbing filtering surface, alleviated to a great extent the blockage problem of large-scale dirt to water pump and heat exchanger.But because the dirty foreign material of sewage are too many, over-burden to cause filtering surface, and in Practical Project, such equipment fault occurs frequently.Because the hydraulic pressure of filtering surface renewing zone is higher than filtering area hydraulic pressure, cause the certainty of mixed water simultaneously, caused heat transmission equipment performance low.
Above-mentioned patent deficiency is still to contain small-sized particle and hair class dirt in the water source after its processing in addition, the water source that enters heat exchanger still can not meet national standard, heat exchange property is still not high, after the operation long period, still occur that dirt increases, especially the dirty foreign material of hair class stop up heat exchanger tube problem.For the current main method of blockage problem, be adopt 2.5-3m/s high flow rate, glueballs to clean and automatically clean the methods such as little brush.Although increase flow velocity method, can suppress gathering of dirt, because the increase of flow velocity causes a large amount of pumps consumptions, itself and energy-conservation original intention are disagreed; Glueballs cleans and automatically cleans little brush due to the reason results of use such as technique bad, thereby more employing overseas equipments and cause larger investment.For the not high problem of heat exchange property, be mainly at present that the area that strengthens heat exchanger solves, but will increase the investment of system like this.Application number is 201210269219.2 the disclosed a kind of Large Diameter Pipeline shell-tube type fluid bed sewage heat exchanger of patent, has designed the devices such as solid-liquid separator, can be fine solution heat exchanger clean problem, yet can not self anti-cleaning.
Summary of the invention
The deficiency that the present invention exists in order to overcome above-mentioned prior art, effectively solve dirt and cross the problems such as the much and little heat exchanger tube causing that differs stops up, dirt increases, heat exchange efficiency is low, mechanical disorder, provide a kind of dirt that filters arbitrary size, the sewage source heat pump system of online self-cleaning enhanced heat exchange.
The technical solution adopted for the present invention to solve the technical problems is:
Whole system comprises trunk sewer, mechanical grille, water pump, heat exchanger inlet pipeline, hair filter, circulation pipe, control valve b, control valve c, control valve d, control valve e, sewage heat exchanger, solid-liquid separator, heat exchanger water return pipeline, trunk sewer connects mechanical grille successively, water pump, water pump extracts sewage and enters hair filter, what the sewage after hair filter filters entered together with the solid particle in circulation pipe carries out heat exchange to sewage heat exchanger, sewage after heat exchange enters into solid-liquid separator, solid particle after solid-liquid separator separation enters circulation pipe, sewage returns to mechanical grille, in four sewage pipes that wherein sewage heat exchanger connects, control valve b, control valve c, control valve d, control valve e are set respectively, by the switching of control valve switch, plumbing drain are carried out to backwash.
In trunk sewer, sewage enters mechanical grille dirty foreign material is removed, by water pump suction hair filter, the dirty foreign material of the hair class in sewage are removed, it enters sewage heat exchanger together with isolated solid particle in solid-liquid separator, strengthening device exchange capability of heat, prevent that dirt from stopping up the generation with dirt, solid-liquid separator can be separated with solid particle by the sewage after heat exchange, wherein solid particle enters into circulation pipe and participates in next heat exchange, sewage turns back to mechanical grille and carries out backwash, by dirty foreign material refunds in trunk sewer downstream; The sewage heat change face of sewage heat exchanger carries out the coating such as copper facing or plating fluorine to be processed to prevent and the formation that suppresses dirt.
Benefit of the present invention and effect are, thoroughly having solved sewage utilizes in process as Cooling and Heat Source, large-scale dirty foreign material blocking pipe, hair obstruction heat transmission equipment, cause heat transmission equipment bulky and cause the problems such as heat transmission equipment hydraulic performance decline, fault because of mixed water because of dirt, significantly improve system heat exchange property, guarantee that security of system is reliable and stable, can be used for sewage or surface water to utilize heat pump techniques to carry out cold and heat supply as low level Cooling and Heat Source, or refrigerating industry equipment, high-efficiency environment friendly.
