Abstract
The utility model discloses a marsh gas water heater. A gas nozzle is designed to be composed of a jet segment a and a marsh gas and air premixed segment b on the basis of the existing gas water heater. The segment a is provided with an inspired gas bell-mouth (1) and a gas jet hole (2); the tube wall of the segment b adjacent to the segment a is provided with an air vent (3) which is communicated with a premixing hole (4) of the segment b; one end of the nozzle is fixed to a gas distributor, and the other end extends into a gas and air mixed tube. The structure can cause the marsh gas and the air to mix well, which can cause the air and the marsh gas to burn stably and completely in the water heater. The use, the operation and all functions of the marsh gas water heater are the same as those of the existing gas water heater.
Description
The utility model relates to gas heater.
Up to the present, the gas heater that people use has only liquefied gas heating-water and gas water heater, both have extremely similar working principle and formation, and its main system forms by inlet and outlet system, gas burning system, pulse firing system, combustion system and security system.The external source of the gas of this gas burning system (as liquid gas storage tank), by magnetic valve, Air-regulating valves, gas distributor, nozzle, parts such as gas-air mixing tube constitute, nozzle as critical component, its structural representation such as accompanying drawing 1, characteristics are that the nozzle air inlet end is a horn mouth, the gas outlet is the little spray orifice of the about 0.5mm of diameter, lack because of spout is little, there is certain space length between spout and gas-air mixing tube, can bring enough air when making the combustion gas of high flow rate enter mixing tube into sufficiently and reasonably mixes with it, since used combustion gas combustible component height, and have certain pressure, so adopt the nozzle of this structure can satisfy the job requirement of gas heater.
Because above-mentioned gas heater is done combustion gas with liquefied gas or coal gas, then inapplicable to biogas, thus in industrial and agricultural production and people's daily life, possess the place of biogas resource, when using gas heater, one's own biogas is not used, and has caused the irrational utilization and the waste of the energy.
It is the biogas water heater of combustion gas with biogas that the purpose of this utility model just provides a kind of, makes the water heater user who possesses the biogas resource can make full use of the own energy and uses water heater.
For realizing above purpose, technical solution of the present utility model is: on original gas heater basis, the nozzle that is fixed in the gas burning system on the gas distributor is redesigned, new nozzle is made up of the biogas air pre-mixing section of the closing b of jet section a and tubulose, a section air inlet end is a horn mouth that obviously strengthens than former nozzle, outlet gas part is that the aperture is 0.9-1.8mm, the spray orifice of long 1-2mm, have airport near on the b section tube wall of a section, when biogas when a section enters b section premixed pipe, suck air premixed with it from airport.Nozzle one end is fixed on the gas distributor, and the other end stretches in the gas-air mixing tube.
Technique scheme has taken into full account the low characteristics of biogas combustible component in design, make combustion gas when igniting, can reach desirable biogas air mixing ratio, guarantee the stable of biogas water heater and fully burning, having satisfied is the water heater requirement of combustion gas with biogas, concerning the water heater user who possesses the biogas resource, uses the biogas water heater, when rationally utilizing the own energy, to help encouraging the biogas development of resources, promote environmental improvement, have environmental benefit.In addition, because the utility model only need be changed original gas heater combustion gas nozzle, and water heater other system and parts all need not change, and have to make easily, and simple, the convenient characteristics of promoting are installed.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
Fig. 1 is former gas heater combustion gas nozzle structure master cross-sectional schematic.
Fig. 2 is the combustion gas nozzle master half section schematic diagram of the utility model biogas water heater.
Fig. 3 is an A-A face cross-sectional schematic among Fig. 2.
For realize that according to the lower characteristics of the flammable composition ratio of biogas, the utility model redesigns the nozzle in its gas burning system with the combustion gas of biogas as gas heater on the constant basis of existing each system unit of gas heater.As shown in Figure 2, the combustion gas nozzle is divided into jet section a and the biogas air pre-mixing section of closing b forms, a section air inlet end is a horn mouth 1, dimension angle α=45 °, outlet side spray orifice 2 aperture d=1.2mm, long 1mm, the b section is pipe-like, near the symmetrical airport 3 that has two diameter of phi=2mm on the b section tube wall of a section, this hole communicates with biogas premixed hole 4, and 4 apertures, hole are 5mm, the about 20mm of b segment length, nozzle always is about 25mm, and nozzle one end becomes screw thread fixedly connected with gas distributor, and the other end stretches in the gas-air mixing tube.For ease of mounting or dismounting, b paragraph header end profile is the hexagonal shape, and other parts are the garden pipe.
During the biogas water heater working, after opening water intaking valve, gas valve is opened, pulse sparking action, biogas enters spray orifice 2 ejection backs and enters premixed hole 4 simultaneously from airport 3 inhaled airs from horn mouth 1, biogas fully mixes with air enters water heater after premixed gas-air mixing tube, leads to fire row again and meets with spark and light and catch fire.Since the utility model except that the combustion gas nozzle each system unit all with former gas heater, so manipulating of biogas water heater is identical with original gas heater with all functions.
Nozzle b section can be garden pipe, hexagonal pipe or other shape pipe; According to required intensity of a fire size, airport 3 can be one or more; Nozzle and being connected of gas distributor can be threaded or other modes fixedly connected, all these variations all drop within the protection domain of the present utility model.
Claims (1)
1, a kind of biogas water heater, form by original gas heater inlet and outlet system, pulse firing system, the gas burning system that has the combustion gas nozzle, combustion system and security system etc., it is characterized in that: the combustion gas nozzle of this gas burning system is made up of jet section a and the biogas air pre-mixing section of closing b, a section air inlet end is horn mouth (1), its size is obviously greater than former combustion gas nozzle, outlet side fumarole (2) aperture d is 0.9-1.8mm, long 1-2mm; The b section has airport (3) near on the b section tube wall of a section in a tubular form, and this hole is closed hole (4) with the biogas air pre-mixing and communicated; A section end is fixed on the gas distributor of gas burning system, and b section tail end has then stretched in the gas-air mixing tube of gas burning system.
