Abstract
The utility model relates to a flue gas copious cooling utilization system, in particular to a flue gas copious cooling system capable of utilizing flue gas waste heat of a heat supply unit. The flue gas copious cooling utilization system absorbs glue gas waste heat by being provided with a separated-type heat pipe heat exchanger, heats domestic water and heating network water, and reduces temperature of flue gas entering a desulfurizer, thereby achieving the purpose of energy conservation and emission reduction.
Description
Technical field
The utility model relates to the cooling system of utilizing of a kind of flue gas degree of depth, specifically, relates to the flue gas degree of depth cooling system that a kind of heat supply unit fume afterheat utilizes.
Background technology
The Northeast power plant mostly is the heat supply unit with desulfurizer, the flue gas that boiler produces directly enters the desulfurization manufacturing apparatus, due to excess Temperature, cause the desulfurizer duty not good, cause that the slurries evaporation capacity is large, the machinery amount of carrying is large, rate of water make-up is large and the problems such as boiler flue corrosion and the liquid that wafts simultaneously.Fume afterheat can not take full advantage of, and causes heat waste.
Discharge smoke temperature of power station boiler mostly is more than 130 ℃.Present stage, the flue gas of most electricity power enterprises directly enters desulfurizer, and the best entrance flue gas temperature of desulfurizer should be 90-100 ℃, cause the desulfurizer can not be in optimum state work, simultaneously because flue-gas temperature is too high, cause that the slurries evaporation capacity is large, rate of water make-up large and the problem such as boiler flue corrosion.
Present stage, the heat supply network moisturizing in most power stations and the heat of hot water for life draw gas from the low section of steam turbine, draw gas and cause the efficiency of cycle to reduce, and hear rate increases.
For this reason, proposed the cooling system of utilizing of a kind of generating plant flue gas degree of depth, exhaust gas temperature has been cooled to 100 ℃ of left and right, reach the optimum operation temperature of desulfurizer, reduce evaporation capacity, rate of water make-up, heat the heat supply network moisturizing simultaneously, hot water for life, reach the energy-saving and emission-reduction purpose.
The utility model content
Goal of the invention of the present utility model is to propose the cooling system of utilizing of a kind of generating plant flue gas degree of depth.
In order to complete the purpose of this utility model, the technical scheme of employing is:

The accompanying drawing explanation:
Fig. 1 is two unit flue gas deep exploitation system diagrams.
Wherein: the 1st, low-pressure coal saver, the 2nd, separate type heat pipe exchanger, the 3rd, heat supply network deaerating type of cycles, the 4th, chemical raw water box, the 5th, hot water for life case, the 6th, supply-water pump.
The specific embodiment:
Steam power plant is all generally two above unit operations, separate type heat pipe exchanger is arranged on a boiler induced-draft fan outlet horizontal flue, separate type heat pipe exchanger outlet life jellyfish pipe is connected with another boiler heat-exchanger outlet after heat exchanger exit is installed a stop valve, enters boiler.
Two stop valves and an electric control valve are installed on the inlet duct of separate type heat pipe exchanger, and inlet duct directly is connected with heat supply network jellyfish pipe; Draw in addition a pipeline and be connected with life jellyfish pipe between first and second of entrance, and on connecting pipe a stop valve of installation.
Two stop valves are installed on the outlet conduit of separate type heat pipe exchanger, and outlet conduit directly is connected with the outlet heat supply network jellyfish pipe of separate type heat pipe exchanger; Draw in addition a pipeline and be connected with the outlet life jellyfish pipe of separate type heat pipe exchanger between exporting first and second, and on connecting pipe, a stop valve is installed.
Respectively draw on the pipe of the heat exchanger gateway at a boiler draft unit room place on the pipeline heat exchanger gateway pipe cooling to another boiler smoke degree of depth, and on every pipeline, a stop valve is installed, realize the changeable operation of heat exchanger of two stoves.
