Abstract

The utility model discloses a waste heat utilization device of a calcium carbonate calcining kiln, which is characterized in that in production equipment for producing light calcium carbonate, heat generated in a calcium kiln calcining device is transferred through a cooling water pipe; cooling water becomes into water vapor after passing through the high-temperature calcium kiln calcining device; then the water vapor passes through a hot hydrated lime heating device; the heat is transferred to hot hydrated lime, and then the water vapor can be used for carrying out circulation cooling again after being liquefied. In the utility model, the temperature of the calcium kiln calcining device is reduced, and the maintenance cost of the calcium kiln calcining device is reduced; moreover, the water vapor can be used for heating the hot hydrated lime, and thereby, the working section of heating the hot hydrated lime singly by a boiler is reduced and the labor cost is saved.

Description

Calcination of calcium carbonate kiln residual heat using device
Technical field
The utility model relates to the production field of lime carbonate, is specifically related to the production of fine particle calcium carbonate, more specifically relates to the device that utilizes calcium kiln roasting assembly waste heat.
Background technology
In producing the process of fine particle calcium carbonate, hot water ashing commonly used is produced as starting material because the hot water ashing to the greatest extent, whiteness is good.A calcium kiln roasting assembly equipment is arranged in process of production on the kiln top, this equipment is running at high temperature often, iron and steel Yin Gaowen easy deformation, equipment often needs repairing, thus annual maintenance, safeguard and expend a large amount of costs equipment, and can not carry out ordinary production in the maintenance period, influence the normal operation of enterprise, and need in process of production with boiler to hot water ashing heat, need expend a large amount of coals, increased labor cost.
The utility model content
The utility model has overcome the deficiencies in the prior art, provides a kind of and can shift a kind of device that calcium kiln calciner heat energy is used for hot water ashing heating.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of calcination of calcium carbonate kiln residual heat using device comprises water pump, water pipe and circulating water container, also comprises calcium kiln calciner refrigerating unit and hot water ashing heating unit, and calcium kiln calciner refrigerating unit is connected by water pipe with hot water ashing heating unit.
Further technical scheme is that calcium kiln calciner refrigerating unit is to become spiral type to be wrapped on the steel and iron wall of calcium kiln calciner by water pipe.
Further technical scheme is that the interior water pipe of hot water ashing heating unit becomes spiral type to arrange.
Further technical scheme is that thermometer is housed in the circulating water container.
Further technical scheme is to be provided with a valve in water pump and the calcium kiln calciner refrigerating unit water pipe connecting.
Further technical scheme is to be provided with thermometer in the hot water ashing heating unit again.
Compared with prior art, the beneficial effects of the utility model are:
The utility model device has carried out effective transfer with the heat energy in the calcium kiln calciner, be used for the heating of hot water ashing, reduced the temperature of calcium kiln calciner, make the iron and steel can Yin Gaowen and be out of shape, reduced breakdown rate simultaneously, saved maintenance cost, and carried out effective utilization with shifting the heat energy that comes out again, omitted with boiler to hot water ashing heat this workshop section's link, more saved a large amount of coals, this device has not only been saved Financial cost, has also reduced carbon emission, respond low-carbon economy, saved the energy.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, a kind of calcination of calcium carbonate kiln residual heat using device, comprise water pump 1, second water pipe 2, the 3rd water pipe 3, the 5th water pipe 5, the 6th water pipe 6 and circulating water container 8, calcium kiln calciner refrigerating unit 4 and hot water ashing heating unit 7, calcium kiln calciner refrigerating unit 4 is connected by the 5th water pipe 5 with hot water ashing heating unit 7, calcium kiln calciner refrigerating unit 4 is to be wrapped on the steel and iron wall of calcium kiln calciner by 3 one-tenth spiral types of the 3rd water pipe, 6 one-tenth spiral types of the 5th water pipe in the hot water ashing heating unit 7 are arranged, thermometer 9 is housed in the circulating water container 8, be provided with a valve 10 in water pump 1 and second water pipe 2 that calcium kiln calciner refrigerating unit 4 is connected, be provided with thermometer 11 in the hot water ashing heating unit.
Water pump 1 is sent to pure water in the circulating water container 8 in the calcium kiln calciner refrigerating unit 4 by second water pipe 2, valve 10 in second water pipe 2 can be to the size of water, break-make is regulated, pure water is after passing through calcium kiln calciner refrigerating unit 4, heat in the calcium kiln calciner is taken out of, calcium kiln calciner temperature is reduced, and pure water self temperature will become high or become water vapor, pure water is delivered to heat in the hot water ashing heating unit 7 by the 5th water pipe 5 then, be loaded with the hot water ashing in the hot water ashing heating unit 7, pure water is with the ashing of heat transferred hot water, the temperature of hot water ashing raises, detection by thermometer 11, make it temperature and reach the effect that we need, in this process, the pure water that the temperature of pure water reduces or become water vapor is liquefied, flow to again in the circulating water container 8, so that utilized once more, be provided with thermometer 9 in the ring water receptacle 8, be used for a detection to water temperature.
