Description
(1) technical field
The utility model relates to a kind of gas heating stove, belongs to thermal technology's HVAC technical field.
(2) background technology
A large amount of farmlands discarded object (comprising plants such as wheat straw, corn stalk) is burnt by the peasant in the rural area, has caused environmental pollution.For addressing this problem recent years, the national Ministry of Agriculture, the Department of Science and Technology, actively advocate and development biomass energy gasification engineering, make with plants such as wheat straw, corn stalk to be raw material, through certain technological process of production, the straw fuel gas of production has obtained promotion and application in the rural area.But, and there is not the heating stove of winter heating because the physical characteristic (low heat value etc.) of straw fuel gas itself and the product that matches only are used for the kitchen range of cooking on market; In every winter, the peasant has to use coal furnace heating, has both caused environmental pollution, and the life inconvenience has limited the effect that this novel energy gas of straw fuel gas should be brought into play again greatly.Now, the heating stove that with the straw fuel gas is the burning source of the gas also is blank, and its technology relatively lags behind, and it is special-purpose source of the gas with Straw Gas that the rural area needs a kind of, safe and reliable to operation, easy to operate straw fuel gas heating stove.In addition, traditional is that the heating stove of fuel exists following shortcoming with heavy oil, coal, natural gas etc.: the heat exchanger tube of use arrange density cross dredge and spacing unreasonable, cause that heat transfer area is little, heat absorption capacity is low; The fume emission of heating stove mainly is by the nature pressure difference, " pours in down a chimney " phenomenon and flue gas can take place when meeting against the wind, causes burner flame-out when serious, makes combustion gas excessive, security incident easily takes place, and combustion gas has certain toxic to human body.
(3) summary of the invention
The utility model is at the deficiencies in the prior art, provide a kind of rational in infrastructure, easy to use, easy to operate, the thermal efficiency is high, has safety detection and warning function, and is the straw fuel gas heating stove of fuel with stalks such as farmland discarded objects.
The utility model is achieved through the following technical measures.
This heating stove comprises burner hearth, heat-exchanging tube bundle, outlet pipe, water inlet pipe, shell, top cover, burner, the air intake fire door, reflection cambered surface cigarette lid, fume extractor and automatic control alarm device, wherein, the air intake fire door is located at the bottom of shell, top cover be arranged on shell above, the top of burner hearth is communicated with fume extractor, the bottom is provided with heat-exchanging tube bundle, burner is installed in the following of heat-exchanging tube bundle and is communicated with the air intake fire door, the two ends of heat-exchanging tube bundle are compiled the back respectively and are connected water inlet pipe and return pipe, row between the horizontal water tube of heat-exchanging tube bundle, be listed as the arrangement that closely interlaces, heat-exchanging tube bundle is horizontal by a slanted angle, it is suitable for reading that reflection cambered surface cigarette lid is placed on burner hearth, and the automatic control alarm device is equipped with on top cover top.
Described fume extractor is made up of blower fan and chimney, and blower fan is arranged on the chimney.
Described automatic control alarm device comprises ion electrode, warning hummer, indicator lamp, is electrical connection between them.
Described heat-exchanging tube bundle is no less than two-layer baffling, and the horizontal water tube of heat-exchanging tube bundle and horizontal sextant angle are 2～40 °.
The hole diameter of described burner is 1.7～5.0mm.
Described reflection cambered surface cigarette lid is V-shaped.
The utility model is no less than two-layer baffling with the water pipe horizontally set, but enhancing heat transfer solves the too high problem of exhanst gas outlet temperature.Because of some physical characteristic of Straw Gas characteristics such as (low) tar content height working time as calorific value long, by-pass valve control and burner pore can be blocked, can't work, the employing hole diameter is the bottom that the burner of 1.7～5.0mm is installed in burner hearth, has solved the problem that by-pass valve control and burner pore can be blocked.The cast iron cigarette lid of V-arrangement reflection cambered surface has absorbed heat as the module of fume afterheat, has realized the discharged at lower temperature of flue gas.Existing gas heating stove (civilian) operation and control system imperfection, can't understand the duty of heating stove at any time, especially source of the gas interrupts suddenly making the burner operation fray-out of flame, recovers this situation of air feed behind the certain interval of time again and very easily causes danger.For this reason, the utility model can be monitored the flame working condition by the automatic control alarm device, when fray-out of flame, and the alarm signal of sounding.Its workflow: open the stalk gas source valve, with electronic impulse ignition apparatus ever-burning flame is lighted immediately, open heating gas control valve door according to the heating stove needs then, regulate gas consumption, burner is started working.Burner operation, after flame produced, high-temperature flue gas and heat-exchanging tube bundle exchanged, and waste heat covers the heat-absorbing model absorption by the cast iron reflection behind baffling, diffuses into flue by flue gas and enters atmosphere by blower fan.Another effect of blower fan is under the situation of stopping working suddenly when burning, fuel gas in time can be got rid of, and avoids unexpected and takes place.This heating stove then interlaces crossing with intensive tube bank, centre-to-centre spacing, increased heat transfer area and heat absorption capacity like this, has optimized pressure drop and film coefficient of heat transfer simultaneously.
The utlity model has advantages such as reasonable in design, easy to use, dependable performance, effect be remarkable, filled up the blank of domestic straw fuel gas heating stove.
