Description

The alternative environment protection warming stove of straw from village clean fuel
Technical field
The present invention relates to the development of energy conservation and environmental protection and utilization of regenerative energy equipment, in particular to a kind of cleaning combustions of straw from village Expect alternative environment protection warming stove.
Background technology
According to rough estimates in 2017, about 5.8 hundred million people of the existing people in the countryside in China, about 150,000,000 families, winter heating mostly with To dissipate coal be fuel, in order to win blue sky defended war, rural area pilot natural gas of the country in Jing-jin-ji region 2+26 city scopes Substitute that coal-fired cleaning heating is double to substitute work with electricity, more than 470 ten thousand families of cumulative transformation, mainly based on substitute gas, By the transformation of double replacements, great variety has occurred in life in the countryside mode, and surrounding air is obviously improved, but rural area is double Substituting transformation, there is also natural gas supply anxieties, compared with using scattered coal facies, after winter heating expense deduction public subsidies still There is the problems such as larger notch, the subsequent double replacement work in rural area are faced with air source deficiency and higher cost of use, it is still necessary to energetically The cleaning for developing solar energy, geothermal energy, the other forms such as clean fuel substitutes heating system, the annual stalk yield in China there are about 900000000 tons, rural area is resulted from, is mostly used to carry out the purposes such as stalk crushing backfill, papermaking straw pulp at present, such as by the huge straw of yield The stalk clean fuel of compacting is made in stalk part, is used for rural area winter heating, not only solves stalk handling problems, while also solving Determined rural area cleaning heating problem, therefore, stalk clean utilization is imperative.
Currently, stalk cleaning heating is utilized there are mainly two types of pattern, one is the central heating form as unit of villages and small towns, Another kind is the individual heating pattern as unit of family, and the central heating as unit of villages and small towns has investment and operational management mould The restriction of formula, the restriction especially charged, as can solving the problems, such as operation and management mode, future will be straw from village clean utilization It is most promising utilize pattern;The problem for restricting family's stalk heating maximum is that the type of furnace heat exchange efficiency of use is low, and safety is hidden Trouble is more, is not equipped with the mating excessively complexity of environmental protection facility or environmental protection facility, does not have actual use value, be allowed to domestic heating oven Environmental protection generally cannot be up to standard, can not be promoted the use of.
Invention content
The present invention for restrict at present straw heating stove promote and apply generally existing the not up to standard, thermal efficiency of environmental protection it is low and The bottleneck problems such as safety difference are improved, compared with coal furnace under the premise of not increasing heating cost, it is proposed that are met The stalk clean fuel substituted type environment protection warming stove that Environmental Safety requires.
To achieve the above object, the technical scheme is that:It is a kind of clear as the rural area of fuel using stalk compacting burner Clean replacement of fuel environment protection warming stove, including autofeed unit, burning and deashing unit, vapor liquid heat exchange unit, cold Air preheat unit, 3-stage dust-removal unit and automatic control unit.Autofeed unit is located at the side of heating stove, by motor, Speed reducer, conveyer belt and feed bin composition, the unit can control the speed of service of conveyer belt by adjusting the rotating speed of speed reducer, to Inlet amount can be adjusted;Burning and deashing unit are located at the bottom of furnace body, and side is connected with feed bin, by igniter, burner hearth, Fire grate, ash bucket, deflector composition, after the fuel that feed bin enters is by igniter automatic ignition, under the action of preheated air, in stove Carry out oxygen-enriched combusting above grate in burner hearth under quick condition, the lime-ash of generation enters periodically extraction cleaning in ash bucket;Gas-liquid heat is handed over Unit is changed to be made of water inlet pipe, water inlet distributor chamber, vapor liquid heat exchange plate, effluent collection room and outlet pipe, water inlet distributor chamber with go out Water collecting chamber is located at the both sides of furnace body, and homonymy, centre are not connected with the vapor liquid heat exchange plate of inclination arrangement, gas with autofeed unit Liquid heat exchanger plate is located at the surface of burner hearth, and water inlet enters through being located at the water inlet pipe of water inlet distributor chamber side wall upper part connection into moisture The allocated rear into vapor liquid heat exchange plate with room, after vapor liquid heat exchange plate exchanges the heat of fuel combustion for, hot water enters water outlet and receives Collect room and passes through the outlet pipe for being located at the connection of effluent collection room lower sidewall into access customer steam heating pipe net;Cold air preheating unit is by sky Air filter net, cool air inlet, gas gas heat exchanger plate, preheated air room composition, cold air on the furnace body of feeding system homonymy Portion is after air filter screen filters and enters by cool air inlet the preheating of gas gas heat exchanger plate, into opposite with autofeed unit pre- Hot air chamber, and enter below fire grate through hot-air air outlet in bottom;Gas gas heat exchanger plate with it is sagging on vapor liquid heat exchange plate Straight arrangement, two-ply are in tilted layout, and range of tilt angles is 55-75 degree;The gas-liquid heat being in tilted layout in three-level dust removal system Power board, gas gas heat exchanger plate form a two level inclined plate sedimentation room, and simple filter bag type dust-extraction unit is 3-stage dust-removal facility, system Wind turbine pump drainage flue gas is automatically controlled using PLC, keeps the operation of overall process tiny structure.
According to above-mentioned environment protection warming stove, feature is:Pass through the vapor liquid heat exchange plate of inclination arrangement, gas gas heat exchange Board group settles bulky grain pollutant at a two level inclined plate sedimentation room, then removes fine particle dirt by simple filter bag type dust-extraction unit Object is contaminated, makes flue gas qualified discharge, when simple filter bag type dust-extraction unit deashing, opens ash discharging hole, artificial vibration dust-cleaning tightens sack After put back into, dedusting method is suitble to domestic small heating stove to use.
According to above-mentioned environment protection warming stove, feature is:Heat in discharge flue gas is exchanged for by gas gas heat exchanger plate, it will Air preheat needed for burning improves combustion temperature in hearth and the vapor liquid heat exchange plate by inclination arrangement, expands gas-liquid heat exchange Contact area, improve the thermal efficiency of heating stove.
According to above-mentioned environment protection warming stove, feature is:Flue gas emission uses wind turbine pump drainage, and device overall process is using micro- Negative pressure safety is run, and ensures that the pernicious gases such as carbon monoxide do not leak.
According to above-mentioned environment protection warming stove, feature is:It is automatically controlled using PLC, passes through temperature control in outlet pipe first Set water temperature in instrument, the rotating speed for controlling the speed reducer in feeder unit adjust the input amount of stalk fuel, again wind turbine with from Dynamic feeding system power-equipment links, and wind turbine first starts before heating furnace igniting, is closed after wind turbine when flame-out, system run all right can It leans on.
In conclusion the present invention provides a kind of environment protection standard, dedusting method simple possible, thermal efficiency height, operational safety It is reliable and can the rural area winter heating of automatic running clean alternative solution, rural area natural gas, the electricity implemented for country clean Heating substitutes provides a kind of alternative again.
