Description
Technical field
The utility model relates to air entrained concrete and manufactures field, is specifically related to a kind of for air entrained concrete steam pressure still recycling tail gas treatment system.
Background technology
In the production process of air-entrained concrete building block, need by still kettle to building block steam pressure, still kettle is after completing building block steam pressure, still internal gas pressure generally remains on about 1.0Mpa, still inner vapor produces by coal-fired, and burning 100KG coal, still internal gas pressure promotes and is less than 0.1Mpa.In order to economize energy, many enterprises all use union between still kettle, fall gas, are switched to by portion of high pressure steam in the still kettle of other skies, and two still kettles fall after gas reaches balance, and two still kettle internal gas pressures are about 0.5Mpa.In order to again carry out steam pressure operation, one of them still kettle needs emptying, has the steam of half to waste.
For solving the problem, application publication number is that the application for a patent for invention of CN 103978545 A discloses a kind of still kettle tail gas recycle reutilization system, comprise still kettle, curing kilns, boiler and Steam Recovery room, it is characterized in that: described described still kettle comprises kettle, kettle is provided with air inlet, exhaust outlet, and kettle end is provided with kettle cover; Air inlet is connected on boiler exit gas port by pipeline, exhaust outlet is connected to Steam Recovery indoor by pipeline, wherein pipeline is through curing kilns, and the described pipeline through curing kilns part is provided with multiple equally distributed steam vent, and Steam Recovery room is connected on boiler.This kind of still kettle tail gas recycle reutilization system is incited somebody to action, and vapor recycle circulates, and tail gas is connected pipeline to curing kilns discharge with saving heat energy.But because micro-tapping in still kettle is very strong, CO2 content is large, unprocessed and be discharged in curing kilns the air quality that will inevitably affect in curing kilns, indirectly to environment being damaged to the cost also improving environmental improvement simultaneously.
Utility model content
For overcoming deficiency of the prior art, the tail gas that the utility model provides a kind of recoverable still kettle to produce also ensures can not cause in reuse process the recycling tail gas treatment system of secondary pollution.
Air entrained concrete steam pressure still recycling tail gas treatment system, comprises still kettle, curing kilns, it is characterized in that: also comprise wind-heat interchanger and hot channel; Still kettle offers air inlet, exhaust outlet; Heat exchanger comprises exhaust gas chamber and air chamber, described exhaust gas chamber has inlet exhaust gas and offgas outlet, this inlet exhaust gas is communicated with to introduce the high-temperature tail gas in still kettle by pipeline with the exhaust outlet of still kettle and the fresh air in air chamber carries out heat exchange, and this air chamber is provided with fresh air inlet and hot air outlet; Hot channel one end is communicated with hot air outlet, the other end extends in curing kilns, and the tube wall stretching into the hot channel in curing kilns has louvre.
Further, temperature detector is provided with in curing kilns.
Further, also comprise recycling tail gas pipeline, these recycling tail gas pipeline two ends are communicated with the offgas outlet of heat exchanger with the air inlet of still kettle respectively.
Further, heat exchanger also comprises fresh air pipe and for be sent into by fresh air in air chamber and the air after heating to be sent the air blast of air chamber, described air blast is communicated with fresh air inlet by fresh air tube.
Further, fresh air tube is provided with air inflow control valve.
Further, hot channel is provided with capacity control valve.
From above-mentioned to description of the present utility model, the air entrained concrete steam pressure still recycling tail gas treatment system that the utility model provides, by heat exchanger, tail gas that still kettle produces and fresh air are carried out heat exchange, by the air after heating, curing kilns are incubated, thus realize high-temperature tail gas reuse, avoid secondary pollution, large reduction enterprise production cost, the raising competitiveness of product in market, have significant economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of air entrained concrete steam pressure still recycling tail gas treatment system.
Detailed description of the invention
Below in conjunction with accompanying drawing, by detailed description of the invention, the utility model will be further described.
With reference to shown in Fig. 1, air entrained concrete steam pressure still recycling tail gas treatment system, comprises still kettle 1, curing kilns 2, wind-heat interchanger 3, hot channel 4 and recycling tail gas pipeline 5;
Still kettle 1 offers air inlet 11, exhaust outlet 12;
Temperature detector 21 is provided with in curing kilns 2;
Heat exchanger 3 comprises exhaust gas chamber 31, air chamber 32, fresh air pipe 33, air blast 34, air inflow control valve 35, wherein exhaust gas chamber 31 has inlet exhaust gas 311 and offgas outlet 312, wherein this air chamber 32 is provided with fresh air inlet 321 and hot air outlet 322, fresh air pipe 33 is communicated with fresh air inlet 321, air blast 34 is connected on fresh air pipe 33, and air inflow control valve 35 is connected on fresh air pipe 33 for regulating the air inflow entering fresh air in air chamber 32;
Hot channel 4 one end is communicated with hot air outlet 322, the other end extends in curing kilns 2, and the tube wall stretching into the hot channel 4 in curing kilns 2 has louvre 41, and hot channel 4 is provided with capacity control valve 42;
Recycling tail gas pipeline 5 two ends are communicated with the offgas outlet 312 of heat exchanger 3 with the air inlet 11 of still kettle 1 respectively.
The workflow of above-mentioned air entrained concrete steam pressure still recycling tail gas treatment system is as follows:
The tail gas that still kettle 1 produces discharge from exhaust outlet 12 and be admitted in exhaust gas chamber 31, fresh air sends in air chamber 32 by air blast 34; By heat exchanger 3, fresh air lower for temperature in autoclave at high temperature still 1 tail gas in exhaust gas chamber 31 and air chamber 32 is carried out heat exchange, the air in air chamber 32 after heating enters curing kilns 2 through hot channel 4;
