Description

A kind of safe, energy-conservation gas heater

The present invention is a kind of a kind of safe, energy-conservation gas heater that adds warm water with combustion gas.

Known gas heater, still deposit some shortcomings: 1, heat and water pipe and the water tank that is connected, heat collecting sheet because of present gas heater all adopts the atmospheric burning type mode, and the flame temperature that the atmospheric burning type mode produces is the highest about about 650 degree, can't improve ignition temperature.Simultaneously, along with the water consumption size variation, length, size variation also take place in the flame that the glory hole from burner stretches out, this long kind changes, causes the highest zone of temperature on the flame---and flame envelope can not be all the time directly contact with fixing heat collecting sheet or water tank, and low temperature---internal flame contacts with it away from it or the flame and there is flame envelope, must make the not high flame of temperature, efficient reduces in the exchange process of heat energy, and most of heat energy is discharged through flue by radiation.If can adopt as last infrared ray heating techniques of using such as gas-cookers, the infrared radiation panel of the refractory material that the employing special material is made, generation calorific value height, the infrared ray of certain wavelength, this maximum temperature that combustion gas is produced can reach more than 860 degree, and spend greater than 650 of air suspended type, be a kind of flameless combustion mode because of infrared ray again, neither can smoke black heated body, can accelerate the thermal process that is subjected to of heated body on the contrary, reduce heat-energy losses, increase substantially the thermal efficiency, facts have proved its combustion gas expense than general atmosphere or burning saving 20%～30%, because the combustion gas of infrared burner is fully burned, effectively suppress the generation and the discharging of carbon monoxide and nitrogen oxide, eliminated and threatened the hidden danger of health, and do not needed existing expense height, efficient is low, unhandy forced-ventilated gas water heater just can reduce indoor pollution; Have more the difficult fabulous wind resistant character energy that is put out by wind because of infrared burner than atmospheric burner again, and make this gas heater safer, more reliable, and can reduce the safety device various, the cost costliness that has gas heater now.Therefore, change the atmospheric burner on the existing gas heater into infrared burner, just can realize a kind of not only safe but also energy-conservation gas heater.2, existing gas heater is in order to reduce indoor pollution, adopted chimney flue type, balanced type, forced-ventilated gas heater, and on the forced-ventilated water heater because of the flabellum that needs driven by motor is housed, though it has played bigger effect to exhaust gas discharging, but there is inconvenient operation in it, need electricity consumption, the production cost height, the long-term cost of use height of user, dangerous, the shortcoming that the combustion gas waste is big, this be because: existing flabellum all is contained in the toxic emission passage, make heat exchanger time shortenings such as heat energy that combustion gas produces and heat collecting sheet, a large amount of heat energy does not exchange the waste gas that just produces with combustion gas fully and is taken away discharge, and only this device just can reduce the thermal efficiency about 20%; The rotation of existing flabellum is by driven by motor, and motor needs electricity consumption, and component quality and operation conditions change are easy to electric leakage and cause artificial electric shock accidents, the low-tension transformer power supply that is afraid of 20V voltage is become 36V also is prone to the electric shock accidents that transformer burns or leaks electricity; Use the driven by motor flabellum, come exhausting waste gas because of motor etc. has been contained in higher temperature region, the insulation on gas heater reduces, or the gas heater stream time is longer, and this regional temperature is inevitable high, also is prone to the electric shock accidents of insulation damages.And the raising class of insulation improves safety coefficient, can increase considerably production cost, improves cost, and the consumer is inevitable can not to be accepted; The forced-ventilated gas water heater of band fan has only a toxic emission passage, and it is not suitable for having a power failure and uses, limited the scope of application, because of having a power failure, flabellum does not rotate, and be parked in flabellum not suction waste gas not only on the toxic emission passage, and stop exhaust gas discharging on the contrary, combustion gas can't be worked; Because of the velocity of rotation of fan is constant, when being in little fiery state as burner, the waste gas that burner produces is under less situation, heat energy is but got rid of in a large number, and burner is when being in big fire, the speed that the large quantity of exhaust gas that burner produces is discharged slows down and pollutes indoorly, and promptly air enters that the speed of burner and quantity can not satisfy the burning of big fire and the vicious circle that further reduces ignition temperature reduces the thermal efficiency.Therefore, under the premise that security is guaranteed, both can reduce the production cost of gas heater, reduce user's combustion gas cost of use, guarantee that the required air capacity of the exhausted air quantity of discharge amount of exhaust gas or air inlet and burner generation or combustion gas is synchronous, and the impeller that is user-friendly to replaces motor to go to drive the flabellum rotation, this impeller is contained in the pipeline of water flowing and contacts with water, as long as boiling water is had a bath, water must flow, will promote impeller rotation, make the flabellum rotation and discharging waste gas or the air of burning is provided, the rotating speed speed of this flabellum just in time with the water consumption size variation, or the exhausted air quantity that flame size produced on the burner what synchronously, realization fully mixes whole discharges of waste gas or air with combustion gas, and makes heat energy the longest with the time that heat collecting sheet etc. contacts, thermal efficiency height, indoor pollution is few; Water promote impeller have cost low, be not afraid of high temperature, do not need power supply, convenience operation.3, existing gas heater is not all loaded onto the material of heat-insulation and heat-preservation, the especially water heater that uses at cold district; On the one hand burned device heating such as heat collecting sheet, water tank, in heating process, on the other hand this heat collecting sheet, water tank etc. contact with the air of cold again, cross-ventilation with heat-energy losses in atmosphere and the reduction thermal efficiency; Therefore, if can be in the burner shell, material usefulness such as heated heat collecting sheet, water tank is heat insulation, insulation encases, and just can significantly reduce heat-energy losses; If gas heater can be made the alteration of form prolate strip of circular columns, can further improve the outward appearance of the thermal efficiency and raising product.

Purpose of the present invention is exactly to implement the science design that people-oriented, realizes not only safety, but also energy-conservation gas heater, satisfies people's the cheap needs of security needs, product price, the needs that daily use combustion gas expense is few, needs simple to operation; And strengthen manufacturer's product competitiveness, promote the development of gas heater.

The present invention finishes like this: change the atmospheric burner on the gas heater into infrared burner, being about to mixed combustion gas directly heats infrared radiation panel after the glory hole on the infrared radiation panel of being made by special refractory material is housed, and the ultrared flameless combustion that produces certain wavelength, have very strong penetrating and heating efficiency because of infrared ray again, and significantly improve the ignition temperature of combustion gas thereby accelerate the thermal process that is subjected to of heated object, significantly reduce the heat-energy losses in the heating process, become the highest combustion system of the present thermal efficiency.Shapes such as this infrared burner can be done and be in strip, U-shaped, spheroidal, semicircle sphere, circle, infrared burner is provided with combustion gas and the well-mixed space of air, infrared radiation is provided with several burner ports, there are circle hole shape, square hole shape, triangle, ellipse etc. in this hole, there is two equally big on the aperture, the big and littler setting in hole, other end in hole.Especially the infrared burner of semicircle sphere, spheroidal, it is the same just to send out the sun, from the centre to around simultaneously and heating such as heat collecting sheet, water tank, water pipe, rather than concentrate certain some to heat, conduction, convection current, radiation and contact area, temperature height from heat can be made into the gas heater of thermal efficiency increase more than 25%.In order to adapt to summer, winter temperature, infrared burner can be made sectional combustion and form large, medium and small fire.The motor and the relevant electrical equipment that drive the flabellum rotation on the forced-ventilated gas water heater are removed, change into impeller and drive the flabellum rotation; Be about to impeller and be contained in the hydraulic turbine water pump shell, impeller is connected with flabellum, with pump case into and out of water end (W.E.) respectively with gas heater on the ventilating water pipe serial or parallel connection, water mobile in water pipe is contacted with rotating impeller.Because impeller is connected and composed by several blades, or constitute by definite shape, position by several guiding gutters on the impeller, under the cooperation of the water-in and water-out of pump case, impeller automatically with have a bath with the hot water amount what, and change rotating speed synchronously, drive the flabellum speed change and rotate or constant rotation.This impeller can be with the impeller that promotes the shipping row, the impeller on the water pump, the flabellum on the electric fan, the flabellum on the smoke exhaust ventilator, Chiba wheel etc.; In like manner, this impeller shape also can be used as exhausting waste gas or gives the flabellum that send air.Be contained in flabellum on the toxic emission passage or be contained in the passage soil that air is provided to combustion gas, utilize flabellum to rotate to force to discharge outdoor or in the outdoor air suction gas heater to waste gas; Come the mode of suction chamber gas that combustion gas is fully mixed with flabellum, sufficient comburant oxygen is provided and makes the space in the combustion chamber form malleation, the transmission of raising ignition temperature and quickening heat, and it is outdoor to promote the waste gas after burning discharge.And the existing flabellum that is located in the toxic emission passage, make and form negative pressure in the combustion chamber, both reduced ignition temperature, shorten time of contact again, make heat energy and the shortening of the time of staying in gas heater and a large amount of heat energy be pumped to outdoor, thereby existing with driven by motor, be located at the flabellum on the toxic emission passage, thermal efficiency ratio chimney flue type gas heater hangs down about 25% reason.A kind of being equipped with on the gas heater of flabellum is provided with waste gas comb passage and air admission passage simultaneously, and promptly exhaust pipe and air enter pipe; Exhaust pipe and air enter pipe have be arranged in parallel, flue gas leading is enclosed within air hose outer setting, air hose and is enclosed within the outer setting of flue gas leading; The space that the pipe way that makes up two mutual sheathing has air or waste gas to pass through.Two exhaust pipes are set simultaneously, i.e. discharge-channel is in order to guarantee the flabellum of driven by motor, still can use gas heater under to have a power failure, and the passage that makes the waste gas of burning never establish flabellum is discharged; Enter pipe at exhaust pipe or air and load onto flabellum, help the thorough discharge of waste gas, abundant and the combustion gas mixing of enough air, and make under the big fire, combustion gas can not wasted, and wherein a kind of air enters the inlet end of pipe and links to each other with air admission hole on the gas heater shell and use room air combustion-supporting, and the inlet end that another kind of air enters pipe with insert outdoor air duct and be communicated with, combustion-supporting with outdoor air, its other end is enclosed within outside the burner, perhaps is connected with air intake passage on the burner.In order to reduce unnecessary air in the gas heater shell, to flow a large amount of heat energy is taken away, reduce the thermal efficiency, in the shell of gas heater or press close to water tank, heat collecting sheet, the place, combustion chamber loads onto thermostable heat insulation, insulation material, can effectively reduce heat loss, especially effect is more obvious at cold district or when using water heater winter.The shell that impeller is housed is that the turnover outlet pass on the hydraulic turbine is in series with water service pipe or in parallel, loads onto the water transfer valve on the water pipe of parallel connection, can control the water yield of crossing at each branch road pipe upper reaches and controls the maximum (top) speed of impeller.The mode that impeller drives the flabellum rotation has three kinds, and a kind of is that impeller footpath axle links to each other with flabellum, leaks for preventing the mating holes on turning cylinder and the shell, and sealing ring, mechanical seal are housed; It is a kind of that to be impeller through gear link to each other or cooperate with flabellum contacts; Another kind is to connect permeability magnetic material or the contact of magnet magnetic that is being connected on magnet or permeability magnetic material and the flabellum on the impeller, drives flabellum and rotates, and because of this impeller sealed rotational in shell, has thoroughly solved seepy question; But the shell wall between impeller and flabellum must be the material with non-magnetic conduction, because of becoming to flow, the water in magnet and the water service pipe contacts, so, this magnet magnetizes water and automatically with water softening, prolonged service life of water tank, water pipe, improve the suction of heat energy, and improved the heat transference efficiency of water tank, water pipe and water.Blade on a kind of impeller contacts with water and promotes wheel rotation, and a kind of is that arc water-flowing trough on the impeller provides flow channel for water, and the reaction force that water forms promotes wheel rotation.
