Abstract
The utility model pertains to the technical field of the lime shaft kiln, and specifically it is a new type of environment-friendly and energy-saving double bevel lime shaft kiln, which can solve the existing technical problems such as great environmental pollutions of the lime shaft kiln, and low purity and low production efficiency of lime products. The new type environmental-friendly double bevel lime shaft kiln comprises a kiln and heating chambers, the kiln is equipped with at least two heating chambers connecting to the kiln cavity and a bevel is equipped in the kiln above the heating chamber. The kiln is square. The bottom of the kiln wall connects to the air cooler. This utility model has the following beneficial effects by comparing with the existing art: 1. Heating indoor firing which will fire independently, not mixed stowage with the stone, not contaminating the stone, good calcinations quality of the stone, low power consumption and good environmental protection indicators; 2. Continuous and stable production, output available for regulation at any time, high production efficiency and capacity.
Description
Technical field
The utility model belongs to the technical field of lime shaft kiln, specifically is a kind of environment-friendly energy-saving type double slanted lime shaft kiln.
Background technology
The local method calcined lime is well-known to the pollution in bad border, and its energy-output ratio is quite big, and production efficiency is low, mechanization degree is poor, and labor strength is big, is the backward production technique that national requirements is banned, and, during calcined lime, kiln body sodalime stone and fuel mix and put together, cause Wingdale to mix with coal dust easily, pollute lime, make product purity low, of poor quality, operative technique is difficult to grasp the production cost height.
Summary of the invention
The utility model is big for the lime shaft kiln environmental pollution that solves prior art, and lime product purity is low, and the problem that production efficiency is not high provides a kind of environment-friendly energy-saving type double slanted lime shaft kiln.
The utility model adopts following technical scheme to realize: environment-friendly energy-saving type double slanted shaft furnace, comprise the kiln body, and heating chamber, at least two heating chambers of the external setting of kiln, heating chamber is communicated with the kiln intracoelomic cavity, and the kiln body inside of heating chamber top is provided with the slope.The kiln body is square.Kiln body lower end is connected with cooling blower.
Heating chamber is provided with two usually, separates with the kiln body, and fuel combustion is independent, and the high temperature gas flow that burning forms enters the kiln intracoelomic cavity through connecting passage.After being heated building stones and adding from kiln top, form countercurrent movement with the high temperature gas flow that flows into the kiln intracoelomic cavity from heating chamber, building stones are preheated, and when on the building stones approach during heating chamber, the building stones of Contact Heating chamber one side are heated, and the opposite side of building stones is preheated simultaneously; Be heated evenly behind upper and lower two heating chambers of building stones process, and the building stones internal-external temperature difference is little, building stones have been realized the isothermal thermal decomposition process.In this process, fuel independent burning in the heating chamber can not mix with building stones in the kiln body, gives security for calcining high-quality lime.
Building stones enter cooling room after elevated temperature heat is decomposed, freezing air fully contacts with hot building stones in cooling room, and with the heat transferred air, the purpose that reaches cooling building stones preheated air can make full use of the building stones sensible heat; Simultaneously, after the preheating of air, consumption capable of saving fuel, the temperature of combustion of raising coal gas is enhanced productivity.
Heating chamber connection and reasonable arrangement of the present utility model, furnace charge is heated evenly, and thermal decomposition time is long, and the building stones that burn till are active big, can adjust by the adjusting of quantity combusted because of furnace temperature, building stones burning and underburnt phenomenon can not occur, the building stones steady quality of producing.
The utility model adopts mechanical loading, mechanical discharging system, and furnace temperature is equipped with the furnace temperature detection system simultaneously, and full stove operator is few, and the operation of stove heat belongs to the production of continous-stable type, and production output is big.
The utility model compared with prior art has following beneficial effect: 1, fuel independent burning in the heating chamber, do not load in mixture with building stones, and can not pollute building stones, the burning quality of building stones is good, and energy consumption is low, the good environmental protection index; But 2 continuous and stable production, output can be regulated at any time, and its production efficiency height, turnout are big.
