Abstract

The present invention proposes a kind of heat accumulating for heat storage type electric heater.Its main feature is that it is utilized in coal in China production process, the gangue waste material for the enormous amount supervened.By crushing, desulfurization, add in additive, drying, sintering.The heat storage brick that can be used for heat-storage electrical heater is made, performance can meet the requirement of heat storage type electric heater.

Description

A kind of novel heat accumulating
Technical field
A kind of novel heat accumulating of the present invention, belongs to Material Field.
Background technology
Fire coal is the main reason for causing serious haze weather, and northern China heat supply in winter Coal-fired capacity has accounted for total fire coal The sizable share of quantity.For this purpose, governments at all levels have carried out changes electrical engineering by the large-scale heating coal of Government-Leading.2003 The heating coal that Beijing's first choice starts in two rings changes electrical engineering, and used electricity heating equipment is that Spaniard invents " heat accumulation Formula electric heater ".The great advantage of heat storage type electric heater is the paddy electricity being utilized in peak-trough electricity, is conducive to the balance of supply network. Heat accumulating used in heat storage type electric heater is to add a small amount of metal oxide as main material using magnesia and di-iron trioxide Heat storage brick.The quantity of heat storage of magnesium ferriferous oxide heat storage brick reaches 1000kJ/Kg. degree, substantially meets the heat accumulation of heat storage type electric heater It needs.We have found under study for action, MgO, CaO, Al2O3、SiO2All it is good heat accumulating.These oxides are exactly bastard coal The main component of stone.The coal production amount in China in 2015 reaches 3,700,000,000 tons, generates nearly 700,000,000 tons of gangue, gangue into One big harm, the large-scale coal gangue hill that can count on have 2600, take up an area 180,000 mu, the coal gangue hill of mismanagement can also Cause spontaneous combustion, seriously pollute environment, damage the health of the common people.For this purpose, develop it is a kind of for heat storage type electric heater heat accumulation with coal Spoil heat accumulating as main component has highly important economic benefit, social benefit and environmental benefit.The design thus A kind of novel heat accumulating is very important.
Invention content
The present invention proposes a kind of novel heat accumulating, what the purpose invented was realized in:Select sulfur content relatively Low gangue, Al in gangue2O3And SiO2Content not less than 90%, wear into 50~100 purposes with pulverizer and grinder Powder takes off the organic and inorganic sulfur in gangue using microbial desulfurization method.The ingredient of heat storage brick is:82~90% bastard coal The flake graphite of+3~4%400 mesh of modified acroleic acid fat glue of sodium metasilicate+2~6% of stone+5~8%.82~90% bastard coal Stone powder and 2~4% flake graphite mixing after mix with modified acroleic acid fat glue and sodium silicate solution, be molded, dry, to containing Water is less than 0.5%, is put into sintering furnace, 950~1050 degree of temperature.The ingredient of heat storage brick is after sintering:95~97% (Al2O3+ SiO2)+2~4% flake graphite+1% MgO+CaO.
The advantages and positive effects of the present invention:
Profit of the invention proposes a kind of novel heat accumulating, its main feature is that storage and very harmful gangue waste material is utilized As the raw material of heat accumulating, industrialization is had been carried out.
Specific embodiment
Embodiment:
Specific embodiment:1st, the low sulfur content gangue 900Kg of Yangquan Shanxi coal mine is selected, is added with pulverizer and grinder Work takes off the organic and inorganic sulfur in gangue little particle with microbial method, adds in the piece of 40Kg400 mesh into the little particle of 50 mesh Shape graphite stirs evenly, and adds in 20Kg modified acroleic acid fat glue, and 40Kg sodium silicate solutions stir evenly;It is put into former and is molded Afterwards, it is put into drying oven and is dried to water content less than 0.5%.It is put into sintering furnace, 1000 degree, is sintered 18 hours, becomes heat accumulation Brick.Reach 1180kJ/Kg. degree with the heat accumulation that gangue is the heat storage brick that main material produces, heat storage type electric heater can be met Requirement.

Claims (1)

1. a kind of novel heat accumulating, the gangue that selects sulfur content relatively low, Al in gangue2O3And SiO2Content not Less than 90%, 50~100 mesh powders are worn into pulverizer and grinder, having in gangue is taken off using microbial desulfurization method Machine and inorganic sulfur;The ingredient of heat storage brick is:The modified acroleic acid of sodium metasilicate+2~6% of 82~90% gangue+5~8% The flake graphite of+3~4%400 mesh of fat glue;After 82~90% bastard coal stone powder and the mixing of 2~4% flake graphite with 2~ 6% modified acroleic acid fat glue and the mixing of 5~8% sodium silicate solutions, molding, drying to water content are less than 0.5%, are put into sintering Stove, 950~1050 degree of temperature;The ingredient of heat storage brick is after sintering:95~97%Al2O3And SiO2+ 2~4% flake graphite+ 1% MgO and CaO.
