Description
Technical field
The utility model belongs to negative pressure power equipment field, especially utilize the heat energy such as high-temperature gas, internal-combustion engine hot gas or tail gas, the high-temperature gas that factory discharges that solar energy, underground heat, inflammable matter burning produce to import cylinder, utilize the heat radiation of high temperature media gas in cylinder and cylinder outside to form temperature difference, make enclosed cylinder produce negative pressure thermal power transfer is become the power equipment of kinetic energy.
Background technique
Traditional power equipment has steamer, internal-combustion engine, external-combustion engine.
Steamer: be unable to do without boiler, not only heaviness but also huge of whole device; The pressure and temperature of initial steam can not be too high, and exhaust pressure can not be too low, and the thermal efficiency is difficult to improve; It is a kind of reciprocator, inertia confinement the raising of rotating speed; Working procedure is discontinuous, and the flow of steam is restricted, and has also just limited the raising of power.
Internal-combustion engine: complex structure, higher to demanded fuel, the cleanliness of fuel is required strictly to environmental pollution.
External-combustion engine, if Stirling engine is wherein a kind of, Stirling engine and internal-combustion engine relatively possess following advantage:
Be applicable to the various energy, no matter be liquid, gaseous state or solid-state fuel, in the time adopting heat-carrying system (as heat pipe) indirect heating, almost can use any high temperature heat source (solar energy radioisotope and nuclear reaction etc.), and motor itself (except heater) does not need to do any change.Stirling engine, without compressor boost, uses general blower fan to meet the demands, and allows fuel to have higher impurity content simultaneously; Stirling engine single-machine capacity is little, and unit capacity is from 20-50kw, the increase and decrease power system capacity that can suit measures to local conditions; Simple in structure, number of components is fewer 40% than internal-combustion engine, and room for price-cut is large; Maintenance cost is low.
Stirling engine is in the time of operation, due to continuous burning in the firing chamber of fuel outside cylinder, the working medium that is independent of combustion gas is absorbed heat by heater, and press Stirling circulation and externally do work, therefore avoid pinking acting and the intermittent combustion process of similar internal-combustion engine, thereby realized efficient, low noise and low emission operation.Efficient: overall energetic efficiency reaches more than 80%; Low noise: at the bottom of 1 meter of bare machine noise in 68dBA; Low emission: exhaust emissions reaches Europe 5 standards.
Because working medium is not burnt, external-combustion engine has been avoided the quick-fried acting problem of the shake of traditional combustion engine, thereby has realized high efficiency, low noise, low pollution and low operating cost.The external-combustion engine various inflammable gass that can burn, as rock gas, biogas, petroleum gas, hydrogen, coal gas etc., the also liquid fuel such as incendivity diesel oil, liquefied petroleum gas (LPG), can also burn wood, and utilizes solar energy etc.As long as hot chamber reaches 700 DEG C, the equipment operation of can doing work, ambient temperature is lower, and generating efficiency is higher.The advantage of external-combustion engine maximum is to exert oneself not affected by altitude with efficiency, is very suitable for high altitude localities and uses.
Simultaneously Stirling engine remain subject matter and shortcoming be: manufacture cost is higher, and working medium sealing technique is more difficult, and reliability and the life-span of Sealing also have problems, and cost of material is high, and power adjustments control system is more complicated, and machine is comparatively heavy; The cost of expansion chamber, pressing chamber, heater, cooling chamber, regenerator etc. is high, and heat loss is 2-3 times of explosive motor etc.
Organic rankine cycle system comprises pump, vaporizer, decompressor, generator, condenser etc.Heat collector absorbs solar irradiance, and in heat collector, heat exchange medium temperature raises, and heat transferring medium is passed to organic working medium by vaporizer heat.Organic working medium is level pressure heating in vaporizer, and the gaseous state organic working medium of high pressure enters decompressor expansion acting, drives generator generating; The organic working medium that decompressor afterbody is discharged enters level pressure condensation in condenser, and the organic working medium of condensator outlet enters vaporizer and completes power generation cycle one time after pump pressurization.
Organic rankine cycle system exists conversion efficiency not high, and volume is large, need to be by baroque decompressor acting.
Summary of the invention
The cost that the utility model has overcome the expansion chamber that Stirling engine exists, pressing chamber, heater, cooling chamber, regenerator etc. is high, and heat loss is the problems such as 2-3 times of explosive motor; Having overcome organic rankine cycle system needs decompressor or steam turbine, the technical barrier that manufacture cost is high.The parallel motion negative pressure power equipment the utility model proposes is to pull piston acting cylinder being carried out to cooling generation negative pressure after heat absorption.
The utility model provides that a kind of thermal energy conversion efficiency is high, can adjust the negative pressure motor device that high-temperature gas air inflow is adjusted output power, can be adjusted by adjusting temperature output power, machine stable output power within the scope of peak output.
The technical solution adopted in the utility model is: a kind of parallel motion negative pressure power equipment, comprise connecting tube, breather check valve, cylinder cap, gas exhausting valve, cylinder, piston, piston ring, pull bar, radiator and casing, it is characterized in that: pull bar two ends are respectively equipped with piston, piston is located in cylinder, and piston is provided with piston ring; Cylinder top dead center top or cylinder cap are provided with breather check valve, and cylinder is provided with gas exhausting valve, and breather check valve connects connecting tube, and cylinder skin is casing, and casing skin is provided with radiator.
