Description
Technical field
The present invention relates to a kind of rural area with heated kang smoke evacuation and air exchange system, belong to northern country winter heating equipment and building energy saving field.
Background technology
For the northern China rural area, because it is in severe cold or cold district on geography, the specific condition in rural area determines it equally with the city not adopt central heating, so the heating of farm building in winter is that an outstanding usefulness can problem.Show that according to investigations the northern country energy resource consumption accounts for 56% of national rural area total energy consumption, and be used for the heating demand above 80% rural energy consumption.Because it obtains easily, conveniently store, the rural area is mainly used to originate and is biomass energies such as stalk, fuel wood, about 600,000,000 tons of the annual biomass energy total amount of using in China rural area, wherein about 60% as fuel confession heating and cooking.
Present stage, the main heating system in rural area still was a heated kang, and heated kang is a kind of ancient heating system, and heat that biomass energy burning capable of using produces improves indoor temperature to use heated kang to heat, and improves indoor thermal environment.Yet; At present; The construction of a heatable brick bed lacks the theoretical foundation support mainly based on experience, and this can produce a series of problems with regard to causing a heatable brick bed in process on probation; The dwelling house ubiquity that northern China utilizes heated kang to heat problems such as indoor temperature is low excessively, heating energy consumption is big, seriously polluted: the dwelling house room temperature generally can only remain on about 10 ℃, but the amount of consumption biomass energy is up to 30-40kg mark coal/m
2, this numerical value has reached 1.5 ~ 2 times of urban heating energy consumption; In addition, because heated kang falls the air pollution that cigarette and biomass combustion cause easily, thereby cause the generation of diseases such as breathing problem, chronic lung disease, lung cancer, asthma, serious harm people's life security.As so all defective cause heated kang to have being used gradually commodity can the trend that substitutes of heating system; Having some places to introduce commercial energys such as coal, electricity at present heats; Because rural area heating equipment inefficiency; Certainly will consume a large amount of commercial energys, this will increase the weight of fuel in China's rural areas supply burden if things go on like this, also can bring heavy pressure for the sustainable development of China's economy and society.
According to weather, the energy characteristics of northern country, seeking suitable heating system is current farm building energy-saving field important topic.At present, increasing heating system appears at the rural area, like the native heating installation of fire coal and stove, family with biomass gasifying furnace etc.Yet these modes excessively rely on commercial energy or biomass energy switch technology with high costs, are not suitable for the vast rural area of present stage.In conjunction with history and geographical environment; The distribution of considering a heatable brick bed is wide, consumption big, historical remote, relate to experience foot, the far-reaching characteristics of inside information; A heatable brick bed in the present use is improved and innovate is the energy-conservation key technology of farm building, is related to the sustainable development of rural energy.
Tradition is landed heated kang has shortcomings such as area of dissipation is little, the thermal efficiency is low, surface temperature is uneven, indoor thermal comfort difference; Built on stilts a heatable brick bed overcome these defectives to a certain extent; Increased heat exchange area and area of dissipation, reduced heat loss, but also self shortcoming has been arranged: heated kang is to be main with the heat loss through radiation mode; Distance has only 20 ~ 30mm between following a heatable brick bed plate and the ground; If following a heatable brick bed plate has only one side to ventilate, its heat dissipation capacity is difficult to get into occupied zone and mainly passes to ground with the mode of heat loss through radiation, and heat is finally through the ground loss.In addition, tradition is hung a heatable brick bed immersion heater, cool also soon, and the warmer end of a kang a heatable brick bed tip temperature difference is bigger, and exhaust gas temperature is high, and heat loses through flue gas in a large number, and efficient is low.
Summary of the invention
The purpose of this invention is to provide a kind of rural area with simple energy-economized type heated kang smoke evacuation and heat-exchange system; In order to overcome present heated kang inefficiency; The shortcoming of IAQ difference; And reduce the possibility of cigarette to a certain extent, and and make in the heat inlet chamber that a heatable brick bed base plate sheds, reach energy-conservation and improve indoor air environment, improve the purpose of the thermal efficiency and comfortableness.
The present invention addresses the above problem the technical scheme of taking to be:
The rural area is with simple energy-economized type heated kang smoke evacuation and heat-exchange system, and said smoke evacuation and heat-exchange system comprise heated kang and air channel, and the part that heated kang contacts with external wall is equipped with cold wall heat-insulation layer in a heatable brick bed; The outside of heated kang is provided with cooking stove, and a heatable brick bed wall that is positioned at the warmer end of a kang one side is provided with into mouth, and a heatable brick bed wall that is positioned at a heatable brick bed tip one side is provided with exhaust opening; The a heatable brick bed floor level is fixed on a plurality of a heatable brick bed lower supporting rods, is fixed with pillar in smoke-choking wall on top end of kang and a plurality of a heatable brick bed on a heatable brick bed base plate, and the kang panel level is fixed on the interior pillar of a plurality of a heatable brick bed; Cooking stove communicates through the dust stratification pond in advancing mouth and being arranged on heated kang, and exhaust opening communicates with return air hole and flue, and the return air hole is arranged in the heated kang; The porch of exhaust opening is provided with the base that facings the wind; Flue and air channel separate through the heat exchange dividing plate that is arranged between the two, the top in air channel be arranged on outdoor air inlet and be communicated with, the bottom in the air channel is provided with air-introduced machine near the air outlet place; Be provided with smoke plugboard on top end of kang between flue and the exhaust opening, the upper end of flue is provided with chimney and chimney cowl.
The invention has the beneficial effects as follows: 1. effectively reduce the heated kang phenomenon of falling the cigarette, the smoke pollution of avoiding room air to be flow backwards; 2. absorb fume afterheat, reduced exhaust gas temperature, improved the thermal efficiency; 3. improved the radiant heat that hangs a heatable brick bed lower shoe at present and be difficult for getting into the zone of action, be prone to through the lost defective in ground, the heat that has effectively utilized the radiation of a heatable brick bed base plate to shed makes it get into the zone of action, has reduced the unavailable heat loss; 4. feed outdoor new wind to indoor, helped improving IAQ, reduced indoor pollutant content, helped the healthy of movable personnel.
