Background technology
Known in the industry, the electrophoresis rinsing tank heating system of traditional aluminum profile industry generally adopts the coal-burning boiler heating, but there is following drawback in such scheme:
1, environmental protection aspect---take coal as fuel, there are the pollutants such as waste gas, waste residue to produce;
2, energy-conservation aspect---energy efficiency is the highest only to be reached about 70%, and Coal Quality is unstable, little when large during firepower;
3, economical aspect---select to build machine room in strict accordance with national regulation, need the annual test expense every year, payment fuel transport and carrying cost arrange staff on duty;
4, secure context---there are the potential safety hazards such as coal stove gas leakage, poisoning, fire, the bursting of boilers;
5, installation aspect---build the boiler room, carry distance far away, thermal losses is large;
6, use---need special messenger's operation, keep an eye on, investment in human resources is large.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, for aluminum profile industry provide a kind of safe and reliable, environmental protection, energy-conservation, reduce the electrophoresis rinsing tank heating system that cost, aluminum profile industry flexible for installation, easy to operate, that automation is high are used.
For achieving the above object, technical scheme provided by the present invention is: the electrophoresis rinsing tank heating system that a kind of aluminum profile industry is used, it includes electrophoresis rinsing tank, it also includes cooling-water machine and separate unit or many water source heat pump units, wherein, described separate unit or many water source heat pump units are connected to form closed circuit by chilled water circulation line or the cooling water circulation pipeline of cold side circulation pipe and cooling-water machine, and at the pipeline place that this cooling-water machine is connected with cold side circulation pipe water inlet pipe separate unit or many parallel circulating water pumps are installed; Simultaneously, this separate unit or many water source heat pump units also are connected to form closed circuit by the entery and delivery port of hot side circulation pipe and electrophoresis rinsing tank, and the water circulating pump of separate unit or many parallel connections is installed at the pipeline place that this electrophoresis rinsing tank is connected with hot side circulation pipe water inlet pipe.
Described electrophoresis rinsing tank heating system also includes attemperater, water purification machine, plate type heat exchanger, and wherein, plate type heat exchanger one side water inlet is connected by water pipe with electrophoresis rinsing tank, and its delivery port is connected with sewage draining exit; The entery and delivery port of plate type heat exchanger opposite side is connected with water purification machine, attemperater by water pipe respectively; This attemperater is connected in another water inlet of electrophoresis rinsing tank through water supply pump simultaneously.
The entery and delivery port of described attemperater is connected to form closed circuit by hot side circulation pipe and water source heat pump units, and at this delivery port circulating line separate unit or many parallel circulating water pumps is installed.
The present invention has the following advantages after having adopted such scheme:
1, environmental protection aspect---take the chilled water (or cooling water) of cold machine as thermal source, use environmental protection refrigerant, non-pollutant discharge, the cold water of discharge can also return cold machine and use;
2, energy-conservation aspect---the comprehensive energy efficiency ratio can reach more than 8, saves about 70% expense than coal-burning boiler, and uses chilled water to reduce the load of cooling system as thermal source when turning waste into wealth, and improves the Energy Efficiency Ratio of cooling system;
3, save money that the aspect---easy for installation, indoor and outdoor all can be placed, and need not build the boiler room, save investment in land, need not annual test and operation additional cost, need not fuel transport and storage, need not staff on duty, need not complicated maintenance, maintenance;
4, secure context---electricity separation does not exist electric leakage, electrical shock safety hazard, and Automatic Control is saved manpower, reduces the industrial injury malpractice and occurs;
5, installation aspect---flexible for installation, can install nearby, thermal losses is few in the course of conveying;
6, use---wholly computer controlled, need not personnel keep an eye on, easy and simple to handle.

The specific embodiment
The present invention will be further described below in conjunction with specific embodiment.
With reference to the accompanying drawings shown in 1, the electrophoresis rinsing tank heating system that the described aluminum profile industry of present embodiment is used, include electrophoresis rinsing tank 1(and need 70 ° of constant temperature), cooling-water machine 2, attemperater 3, plate type heat exchanger 4, the water source heat pump units 6(of water purification machine 5 and separate unit or many SFXRS-100 adopts the stainless steel 304 shell, its maximum water temperature is 80 degree), wherein, described separate unit or many water source heat pump units 6 are connected to form closed circuit by chilled water circulation line or the cooling water circulation pipeline of cold side circulation pipe and cooling-water machine, and at the pipeline place that this cooling-water machine is connected with cold side circulation pipe water inlet pipe separate unit or many parallel circulating water pumps 8 are installed; Simultaneously, this separate unit or many water source heat pump units 6 also are connected to form closed circuit by the entery and delivery port of hot side circulation pipe and electrophoresis rinsing tank 1, and the water circulating pump 8 of separate unit or many parallel connections is installed at the pipeline place that this electrophoresis rinsing tank 1 is connected with hot side circulation pipe water inlet pipe; Plate type heat exchanger 4 one side water inlets and electrophoresis rinsing tank 1 are connected by water pipe, delivery port is connected with sewage draining exit 9, be used for the discharging of waste liquid, the entery and delivery port of opposite side is connected with water purification machine 5, attemperater 3 by water pipe respectively, and the heat that utilizes plate type heat exchanger 4 to absorb useless tank liquor heats pure water; These attemperater 3 feed water inlets and water supply pump 7 are connected in another water inlet of electrophoresis rinsing tank simultaneously, entery and delivery port links to each other with water source heat pump units 6 by hot side circulation pipe and consists of closed circuit, and at this delivery port circulating line separate unit or many parallel circulating water pumps 8 is installed.After adopting above scheme, the present invention mainly utilizes the heat of chilled water to be thermal source according to the advantage of water source heat pump units 6, produce simultaneously byproduct (cold water) for cooling-water machine chilled water (or cooling water) circulating line 2, reduce the power load of cooling-water machine, thereby improve the Energy Efficiency Ratio of cooling-water machine; Simultaneously the present invention also has automatic water supplement, changes water function, and when the tank liquor plating rate of electrophoresis rinsing tank 1 was higher than job requirement or the decline of tank liquor water level, system can change water, moisturizing work automatically; Also have water source heat pump units 6 of the present invention to adopt Automatic Control, it is constant that tank liquor temperature is kept in automatic operation.In a word, advantage of the present invention is numerous, can overcome better the drawback that the heating of traditional coal-burning boiler brings, and a kind of high-quality, energy-conserving and environment-protective, safe and reliable electrophoresis rinsing tank heating system are provided, and can satisfy customer requirement fully, is worthy to be popularized.
The above embodiment only is the present invention's preferred embodiment, is not to limit practical range of the present invention with this, so the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
