Abstract

The invention relates to a steam boiler and steam turbine set matched combination driven by other energy instead of electric energy, which comprises a steam boiler and a steam turbine, and is characterized in that: steam generated by the steam boiler enters the steam turbine to do work; a through spindle of the steam turbine drives multiple kinds of power equipment which are driven by electric power originally; waste steam of the steam turbine enters a water mixer of a heat supply system to be mixed so as to generate hot water, and the hot water is fed into the tail end of the system for heat supply; heat supply return water at the tail end of the system is fed into a return water reservoir; the heat supply return water in the return water reservoir is fed into the water mixer to be mixed with the hot water, and the mixed water is fed into the steam boiler to serve as boiler inlet water; and the waste steam of the steam turbine also enters a water mixer of domestic hot water through a pipeline to be subjected to heat exchange, and the generated mixed hot water is fed into living quarters through pipelines. By the steam boiler and steam turbine matched combination, the electric energy can be saved, operating cost is reduced, and the mechanical energy of axial rotation generated after the steam turbine does work replaces the electric energy to drive the mechanical equipment of a drive system.

Description

Alternative steam boiler and the steam turbine set of doing transfer motion power by electric energy forms a complete set of

Technical field

The present invention relates to a kind of urban heat supplying equipment, particularly relate to a kind of alternative steam boiler and steam turbine set of doing transfer motion power by electric energy and form a complete set of, except that the alternative electric energy transmission, particularly to the improvement of existing urban heat supplying equipment.

Background technique

Because people are to the concern of global warming and energy security, and cost of electricity-generating is more and more higher, some developed countries have strengthened the development and utilization of new energy in recent years, rise the low-carbon economy development model, include: a series of fresh contents such as low-carbon (LC) industry, low-carbon (LC) energy technology, low-carbon (LC) city and low-carbon (LC) life.It is by increasing substantially efficiency of energy utilization, use the renewable energy sources and the low-carbon (LC) energy on a large scale, research and develop the reduction of greenhouse gas discharge technology on a large scale, building low-carbon (LC) society, maintaining ecological balance.

The heating form at present existing city is mainly: thermoelectricity plant and district boiler room, heating equipment mainly contains: high-carbon coal-fired hot-water boiler and fuel-firing gas-firing water-heating boiler, heating system are mainly transports to the system user warming installation with circulating hot water.

For example there is 152 days heating phase every year the Shenyang City, and so far, heat supply building area in Shenyang has reached 1.96 hundred million square metres, and heating mode needs to consume about 6,600,000 tons of coal in kind every year based on the high-carbon coal-fired hot-water boiler.This heating system is strong to the dependence of coal resources, also environment is caused serious pollution.

And consider from utilization results of energy, the energy of existing heating system uses very unreasonable: hot merit transfer process (condensed steam type unit generation) certainly leads to low grade heat energy loss (heat release in low-temperature receiver of steam turbine steam discharge) on the one hand, allows high-grade heat energy (steam heat that boiler provides) be used for low-grade heat supply on the other hand with devaluing.Though in the cogeneration of heat and power of thermoelectricity plant, can accomplish fuel chemical energy change into high level heat be used for earlier the generating (high-grade heat energy), make the low grade heat energy that was used as merit supply heating hot water then to the user, though primary energy utilizes relatively rationally, but still have exhaust steam emptying more than needed, its energy utilization rate still is necessary further necessity of raising.

For further improving heating efficiency, reduce emission amount of carbon dioxide, what discharge when making full use of fuel combustion enriches heat resource, if steam boiler and the steam turbine set heat supply is considered as a whole and reasonably the comprehensive utilization, make thermoelectricity plant when providing the heating water, can also provide domestic water to the user to the user, and the realization self-powered will be advocated the development low-carbon (LC) economy of energy to China and make certain contribution with the discharge amount that reduces carbon.According to the applicant's retrieval, do not find that the domestic report that has steam boiler and the supporting alternative various electric energy transmission systems of steam turbine set and heating to make up occurs at present as yet.

Summary of the invention

The objective of the invention is to overcome the prior art above shortcomings, provide a kind of alternative steam boiler and supporting heating combination of steam turbine set of doing transfer motion power by electric energy.Steam boiler in the supporting heating combination of this steam boiler and steam turbine set can produce 120 ℃～300 ℃ steam, drive the running of steam turbine set, after entering steam turbine from the steam of boiler, pass through the nozzle and the movable vane of a series of loop configurations successively, the mechanical energy that the heat energy of steam is changed into turbine rotor passes to the former transmission device that need turn round with electric energy, the use field is very extensive, exhaust steam after the steam turbine acting can heat, and also can supply with domestic hot-water's (as: bathing, swimming pool and aquaculture).

The technical solution that the present invention provides is: this alternative steam boiler and the steam turbine set of doing transfer motion power by electric energy forms a complete set of, include steam boiler and steam turbine, constituted the heating that forms a complete set of by pipeline between described steam boiler and the steam turbine, be characterized in

Producing 200 ℃～300 ℃ steam by steam boiler is entered in the steam turbine by pipeline and does work, the logical axle of steam turbine drives the power equipment that various reason electric power are done transmission, the mechanical energy that is the axial rotation of steam turbine process acting back generation substitutes the various kinetic forces of being done transmission by electric energy, producing exhaust steam below 120 ℃ mixes the mixed hot water that produces 65 ℃ and delivers to the terminal heat supply of system through pipeline in pipeline enters the carbonated drink exchanger of heating system, 35 degree heating water returns of system's end are delivered to the backwater wet pit through pipeline, and the heating water return in the backwater wet pit is delivered to respectively through pipeline and participated in mixed hot water in the carbonated drink exchanger and deliver to steam boiler as boiler feed water; The exhaust steam below 120 ℃ that steam turbine acting produces is also carried out heat exchange in pipeline enters domestic hot-water's water-water jet, the mixed hot water that produces 55 ℃～75 ℃ is delivered to the living area for uses such as dwelling house domestic hot-water, bathing pool, swimming pool and aquacultures through pipeline, and the intake pipe of domestic hot-water's water-water jet communicates with outside municipal tap water pipe.

For making full use of the mechanical energy of steam turbine through the axial rotation of acting back generation, the structural type that can adopt a steam turbine or multiple steam turbines or small steam turbine group to be connected with steam boiler respectively by pipeline, the logical axle that makes it single steam turbine drives the power equipment that single reason electric power is done transmission, acting is more stable like this, thereby has guaranteed the Security of equipment and production.

Compared with prior art, the invention has the beneficial effects as follows: owing to adopt forming a complete set of of steam boiler, steam turbine, its advantage is saving power, reduces operating cost, a tractor serves several purposes, increases economic efficiency, and steam turbine drives the machinery of transmission system through the mechanical energy alternative electric energy of the axial rotation of acting back generation.
