Description

A kind of small-sized gas generating residual heat utilized device
Technical field
The utility model relates to the waste heat recovering device technical field in gas electricity unit operation, and what relate generally to is a kind of small-sized gas generating residual heat utilized device.
Background technique
For gas electricity unit, the energy of fuel gas is only had an appointment and 35% by generator set, is converted into electric energy, 30%~35% discharges (temperature of exhaust fume reaches 550 ℃) with high-temperature flue gas, and 20%~25% launched machine cooling water is taken away, and by unknown losses such as fuselage heat radiations, accounts for 10%.More than the energy Ratios useful energy of exhaust heat and cooling water loss.At present, at some large-scale gas electricity stations, because gas electricity unit quantity is many, and install more concentratedly, waste heat amount is very large, therefore, some adopts this intermediate item after the high-temperature tail gas collection of all gas electricity units, produces steam generate electricity by exhaust heat boiler.But, the gas electricity station small-sized to some, because gas electricity unit quantity is few, if adopt cogeneration, relative investment is very large, reclaims benefit much smaller than gross investment, therefore at small-sized gas electricity station, substantially can not do cogeneration project.Now, on market, the UTILIZATION OF VESIDUAL HEAT IN for small-sized gas electricity station, is still in the junior stage, and the method for taking is more single, is mainly to install heat-exchanger rig additional at exhaust pipe, can not maximizedly utilize the waste heat producing in gas electricity unit operation.
Summary of the invention
The purpose of this utility model produces thus, proposes a kind of small-sized gas generating residual heat utilized device, realizes the object of maximum using gas generating residual heat.
The utility model is realized the technological scheme that above-mentioned purpose takes: a kind of small-sized gas generating residual heat utilized device comprises gas electricity unit, cooling water side water-water heat exchanger and gas-liquid type heat exchanger, cooling water side water-water heat exchanger is connected in parallel on the cooling water side pipeline of gas electricity unit, gas-liquid type heat exchanger is connected in parallel on the flue of gas electricity unit, and described cooling water side water-water heat exchanger and gas-liquid type heat exchanger are all communicated with fume side water-water heat exchanger.
The utility model is further connected with thermostat valve on the cooling water pipeline of described cooling water side water-water heat exchanger.
The utility model is further connected with valve on the connecting pipeline of described cooling water side water-water heat exchanger and fume side water-water heat exchanger.
The utility model is further connected with circulating water pump on the connecting pipeline of described gas-liquid type heat exchanger and fume side water-water heat exchanger.
The inlet pipeline of fume side water-water heat exchanger described in the utility model is communicated with elevated tank, and this elevated tank is connected with tap water through softened water processor.
The utility model is by utilize the waste heat of high-temperature tail gas in gas electricity unit operation and the waste heat of cooling water simultaneously, allow low temperature water first absorb the waste heat of cooling water, and then the waste heat of absorption high-temperature flue gas, finally become high-temperature water, for user, produce or live.Realize the object of maximum using gas generating residual heat.And the thermostat valve 7 arranging can be controlled the flow into cold water automatically according to user's the temperature that need to set water, realizes constant temperature water supply.There is feature simple in structure, easy to use, that service life of equipment is long.

Embodiment
By reference to the accompanying drawings, provide embodiment of the present utility model as follows:
Small-sized gas generating residual heat utilized device described in the present embodiment is a cooling water side water-water heat exchanger 8 in parallel on the cooling water side pipeline 9 of gas electricity unit, a gas-liquid type heat exchanger 2 in parallel on the flue 10 of gas electricity unit.Described cooling water side water-water heat exchanger 8 and gas-liquid type heat exchanger 2 are all communicated with fume side water-water heat exchanger 5, on the cooling water pipeline of cooling water side water-water heat exchanger 8, be connected with thermostat valve 7, on the connecting pipeline of cooling water side water-water heat exchanger 8 and fume side water-water heat exchanger 5, be connected with maintenance valve 6.On the connecting pipeline of gas-liquid type heat exchanger 2 and fume side water-water heat exchanger 5, be connected with circulating water pump 4.The inlet pipeline of fume side water-water heat exchanger 5 is communicated with elevated tank 3, and elevated tank 3 is connected with tap water through softened water processor 1.
The present embodiment in use, first cooling in cooling tower enter cooling water side water-water heat exchanger 8 by pipeline, the heat that absorbs cooling water once heats up, and then enter fume side water-water heat exchanger 5 by pipeline, absorption is from the heat of fume side, through again heating up, finally become high-temperature water and offer user.The heat of fume side, by internal softening water under the dynamic action of circulating water pump 4, softened water flows through gas-liquid type heat exchanger 2, absorb the heat of high-temperature flue gas, then transfer to fume side water-water heat exchanger 5, transfer heat to outside cold water, through again heating up, become high-temperature water and offer user.In this process, the product coolant-temperature gage that thermostat valve 7 is set according to user, controls the flow into cold water automatically, realizes the constant temperature water supply of system.Softened water after cooling enters 2 circular flows of gas-liquid type heat exchanger by circulating water pump 4.
