Description

The dimethyl ether fuel gas water heater
Technical field
The utility model relates to the cooking stove that combustion gas is used, and patent application relates to the dimethyl ether fuel gas water heater.
Background technology
Because dimethyl ether fuel gas is a kind of novel Coal Chemical Industry product, it is a kind of novel energy of clean environment firendly, it is the ideal substitute of liquefied petroleum gas and gasoline, diesel oil kerosene, the gas heater that does not meet the dimethyl ether fuel gas special use in the market, though use after existing gas heater can being changed through technology, but bad because of its combustion position, flame instability is not looked at the parent by most of user acceptance.Particularly at " city gas dimethyl ether " CJ/T259-2007 of national correlation department in 2007 issuing and implementation) and on July 27th, 2009 Guizhou Province's house and the Guizhou Province Jian Cheng that issues of town and country construction office send out " suggestion of promoting the use of as city gas about dimethyl ether " file (2009) No. 317, further dimethyl ether is used as city gas and promote, with the form of rules clear and definite legal identity and the status of dimethyl ether as city gas, to develop a combustion gas special-purpose water heater that meets the dimethyl ether fuel gas physicochemical property also extremely urgent for this reason, because dimethyl ether fuel gas is the clean energy resource that Coal Chemical Industry is made, molecular formula is C 2H 6O, the oxygen enrichment coefficient is 34.8%, and the combustion process of its dimethyl ether fuel gas itself is an oxygen-enriched combusting, and required theoretical air coefficient is less than other combustion gas of homogenous quantities volume, for this reason, work out a gas heater that is suitable for the pure Dimethyl ether combustion characteristics and become the task of top priority.
Prove through repeatedly experimental study, it is the combustion position that employed domestic gas-fired water heaters such as liquefied petroleum gas, natural gas, coal gas all can't satisfy dimethyl ether, as the dimethyl ether fuel gas that burns with the used gas heater of above combustion gas, incomplete combustion can occur, produce yellow flame, black smoke, take off phenomenons such as fire, tempering, detonation, and, gas heater is caused certain destruction with the slight blast sound.In whole combustion process, be pungent, smoke an eye phenomenon, and combustion process is incomplete in addition, very easily produces injury healths such as containing CO gas, life and healthy threatening with a spot of.
Summary of the invention
The purpose of the utility model patent is that a kind of pure burning water heater of dimethyl ether fuel gas that meets dimethyl ether fuel gas physicochemical property, ignition quality, combustion conditions is developed in requirement,
The related dimethyl ether fuel gas water heater of patent of the present invention is that the structure of the following burner that passes through realizes that they are: five parts such as burner, aqueous vapor linkage, igniter, heater, attemperating unit, flame-out protection device are formed;
Dimethyl ether fuel gas water heater hull shape is a cuboid, and its face equipment has four seasons air volume regulating valve, the flame control valve, and water regulating valve and flame observation panel, lower housing portion picks out cooling water inlet, hot water outlet, its ventilating opening is opened both sides, and exhanst gas outlet is driveed on top; Dimethyl ether combustion distribution device is mainly installed in the inside of dimethyl ether fuel gas water heater, and the return pipe around distributing is close to the combustion chamber and is wrapped in ring-like copper plumbing on the heater, enters the water regulating valve control of return pipe water by the cooling water inlet end; Air inlet is connected with magnetic valve, the Kai Heguan of control combustion gas, the switch of magnetic valve is controlled by water regulating valve, the moisture film sheet of the aqueous vapor linkage of pressure in control valve acts on dimethyl ether combustion distribution device that hydraulic pressure produces, microswitch is opened, connect toward the power supply of electromagnetic valve switch and ignitor, opens solenoid valve, combustion gas enters dimethyl ether combustion distribution device, enter the ignition of burner ignitor through gas nozzle, the heat that burned flame produced, pass to and be close to combustion chamber return pipe all around, the water in the pipe is heated, gas fume after burning is discharged outdoor through exhanst gas outlet with airduct.
The utility model mainly is to have solved dimethyl ether to add thermal effect in the special use during as water heater fuel of replacement liquid liquefied oil gas, coal gas, natural gas, to satisfy current many at home technical barriers of solving of still not having.The utility model patent has solved the combustion conditions of dimethyl ether fuel gas as the water heater heating fuel effectively, hot-water heating system efficiently, satisfy the daily pouring of people (washing one's hair) effectively and bathe living needs, in China effectively with dimethyl ether as domestic gas in addition promotion and application established comparatively solid foundation.
All encapsulants of the utility model patent all adopt the PTFE of the anti-dimethyl ether corrosion of energy, have improved the security performance of dimethyl ether fuel gas special-purpose water heater when pure dimethyl-ether, have prolonged the service life of dimethyl ether special-purpose water heater.
