In ceramic building material industry, drying is one of most important process in ceramic production technology, and spray drying is exactly will
Ceramic mud spray gun sprays mist formation drop-wise in drying tower, is in contact with the hot wind entered from spray drying top of tower, due to
Droplet is thin, has huge disengagement area, almost just completes drying in moment, the graininess powder to be meeted the requirements, accumulation
It is drawn off by discharge valve in bottom of tower.Generation that the heat source of drying equipment is often oil, coal gas, coal, natural gas burn in hot-blast stove
Hot gas.Dry required hot air temperature is 500 DEG C or so, since the flue-gas temperature for generation of directly burning in hot-blast stove is up to 1000
DEG C or more, therefore mixing portion cold air is needed to reduce the inlet temperature of stabilizer of hot gas.According to statistics, energy consumption in the drying process accounts for work
The 15% of the total fuel consumption of industry.
Defect of the existing technology is, due to the flue-gas temperature for generation of directly burning in hot-blast stove be up to 1000 DEG C with
On, drying makes to also need to cool down to flue gas, causes the waste of the energy.
Utility model content
It is more fully spray-dried in view of the above-mentioned problems, the utility model is intended to provide a kind of more energy saving, using energy source
System.
The technical solution that the utility model solves the problems, such as is：A kind of spray drying system for ceramics, including drying tower,
The feeding device for being set to the spray gun at the top of drying tower, being connect by pipeline with spray gun, further include Gas Turbine Generating Units, with
The grid-connection cabinet that Gas Turbine Generating Units pass through cable connection；

It connects, and the flue gas in the first smoke discharge tube is passed through drying tower inner cavity；
The utility grid of the grid-connection cabinet and workshop is grid-connected.
Although the comprehensive energy efficiency of NG Distributed Energy System is very high, flue gas utilization will be through excess enthalpy
The later realization energy cascade utilization of hot equipment heat exchange, energy inevitably has loss after heat exchanger.Said program is direct
The high-temperature flue gas generated after gas turbine power generation is passed through in drying tower, without heat exchange, without energy loss.In addition, many institutes
Known, for the high-temperature flue-gas that Gas Turbine Generating Units generate just at 500 degree or so, this temperature is precisely that ceramics are dry
Required temperature, without carrying out cooling processing to high-temperature flue gas, all are all just right, can maximumlly utilize thermal energy, protect
Demonstrate,prove not waste of energy.
Gas Turbine Generating Units electricity is incorporated to after utility grid for used in plant produced, whole system has high
Comprehensive energy utilization ratio.
Further, further include fuel gas hot-blast stove, fuel gas hot-blast stove is equipped with the second smoke discharge tube, the second smoke discharge tube
Outlet connect with drying tower, and the flue gas in the second smoke discharge tube is passed through drying tower inner cavity；
Bifurcated is equipped with cold air pipe on the second smoke discharge tube.
Theoretically only need gas turbine provide heat source with regard to much of that, but will appear in Practical Project turbine engine failure or
Person, which overhauls, to be needed, and with spare, directly the burn high-temperature flue gas of generation of fuel gas hot-blast stove needs to be mixed into cold sky setting fuel gas hot-blast stove
Gas cools down, to reach the required temperature of dry ceramics.
Further, bifurcated is equipped with the bypass flue communicated with air on the first smoke discharge tube, is set on bypass flue
There is throttle valve.
The purpose that bypass flue is arranged is that when feeding more than demand, extra flue gas can pass through high-temperature flue gas
In line bypass flue discharge.
Specifically, the dry tower bottom is equipped with discharge port, drying tower is connected with one cyclonic in turn by pipeline and detaches
Device, secondary cyclone, deduster are equipped with air-introduced machine between deduster and secondary cyclone.
Specifically, the feeding device includes charging pump, the hopper that is connect by pipeline with charging pump.
The separation dedusting structure and feeding device of drying tower are routine techniques.
The utility model has expanded existing natural gas distributed energy UTILIZATION OF VESIDUAL HEAT IN form, realizes in ceramic building material industry
Initiative application, specific remarkable result shows：
1. directly the high-temperature flue gas generated after gas turbine power generation is passed through in drying tower, UTILIZATION OF VESIDUAL HEAT IN need not be connect and set
It is standby, without heat exchange, without the loss of waste heat conversion process.
2. change traditional ceramics building material industry using to be also mixed into after hot-blast stove cold air could enter drying tower it is this
High energy consumption mode, using Gas Turbine Generating Units, for the high-temperature flue-gas of generation just at 500 degree or so, this temperature is proper
It is the dry required temperature of ceramics well, without carrying out cooling processing to high-temperature flue gas, all are all just right, can be maximized
Using thermal energy, ensure not waste of energy.
3. Gas Turbine Generating Units electricity is incorporated to after utility grid for used in plant produced, whole system has pole
High comprehensive energy utilization ratio.This increased self-generating system all the way can ensure energy source station and other under special circumstances
Part important load electricity consumption.
