Description

Curing System {CURING SYSTEM}

The present invention relates to a curing system, and more particularly, to a curing system for generating steam directly from the exhaust gas and supplying the steam and the exhaust gas together to the concrete mortar.

Curing of concrete is carried out by providing a constant steam to the concrete mortar at high temperatures. For example, when curing a 1.5 x 1.5 m ² precast panel, the temperature is gradually raised to 60 degrees over an hour or two, maintained at about 6 hours, and then gradually cooled over about 2 hours. In the early stages of curing, moisture is released from the concrete mortar, but after that the moisture of the supplied steam is absorbed by the concrete mortar.

Conventional curing systems have generally been a system for supplying and controlling temperature and moisture by boiling water to produce hot steam and supplying it to concrete mortar.

However, such a system had a disadvantage of being inefficient in terms of energy and equipment.

That is, since the temperature of steam produced by boiling water and the gas including the same is only about 100 ° C., it is difficult to provide a high temperature, especially in winter. To this end, the curing system is generally installed underground, which leads to an increase in installation costs.

In addition, since the exhaust gas generated in the process of burning oil or the like to boil water is discharged separately from the vapor-containing gas supplied to the mortar, thermal loss is inevitable, which leads to low energy efficiency and environmental pollution.

In addition, it is impossible to properly control the temperature and water supply with only the vapor-containing gas, so that a boiler apparatus for forming steam and a separate heating apparatus for providing temperature are used, which are also very inefficient in terms of installation cost and energy. Will be called.

Accordingly, the present invention has been proposed in view of the above contents, and an object thereof is to provide a curing system having advantages such as high energy efficiency, low equipment cost, environmental friendliness, and ease of control.

The object is a curing system configured to cure concrete mortar inside a mold, comprising: a combustion device for burning a predetermined fuel; Exhaust flue flue gas exhausted from the combustion apparatus; A water injection unit for generating steam by injecting water into the exhaust flue; And it can be achieved by the present invention characterized in that it comprises a steam supply line for introducing the exhaust gas containing the steam into the mold.

Here, it is preferable to further include a control unit for controlling the amount of combustion of the combustion device to adjust the temperature of the exhaust gas, and for controlling the operation of the water injection unit to adjust the amount of steam generated. In addition, the combustion device is preferably an incineration device for incineration of waste in terms of efficiency.

In addition, the present invention may further include a water storage unit configured to store the water and surround at least a portion of the combustion device so that thermal energy of the combustion device is absorbed in the water.

Here, the temperature sensing unit for measuring the temperature of the water stored in the water storage; And a water supply unit for adjusting a supply amount of water supplied to the water injection unit based on the measured temperature of the temperature detection unit. In addition, it may be effective to prevent a safety accident further comprises a pressure regulating valve for exhausting the generated steam to the steam supply line when the water vapor pressure in the water storage unit rises above a predetermined value.

In addition, the present invention includes a water supply unit for sucking and pumping the water of the water storage unit so that the water injected into the water injection unit is injected at a high pressure; A steam supply unit connected to the steam supply line to forcibly convey the heat of steam generated at the water injection unit and exhaust gas to the mold side; A pressure sensing unit installed to sense an internal pressure of the steam supply line; And a controller configured to control driving of the water supply unit and the steam supply unit such that the internal pressure sensed and applied from the pressure detector is equal to or less than a predetermined set pressure.

The incineration apparatus may include: a melting vaporization chamber including a waste inlet for introducing waste petrochemicals, a first air supply for supplying air, and a first gas outlet for discharging gas of the waste petrochemicals vaporized; And a firewood inlet for inputting firewood, a gas inlet for injecting the waste petrochemical gas from the first gas outlet, formed at a bottom on which the firewood is accumulated and combusted, and a second air supply hole for supplying air. And a combustion chamber in which a second gas outlet for discharging the combustion gas generated by the combustion of the firewood and the waste petrochemical gas is formed, wherein the combustion chamber is located above the melting vaporization chamber, and the melting vaporization chamber is located in the combustion chamber. The waste petrochemical gas is generated by receiving heat generated by combustion of the waste petroleum gas, and the waste petrochemical gas is guided to the firewood combusted in the combustion chamber by the gas inlet so that the combustion occurs completely. This can reduce the occurrence of dioxins and the like.

Thus, according to the present invention, it is possible to generate steam directly, for example, in a high-temperature exhaust gas of 300 ° C. or higher, and supply the exhaust gas containing steam to the concrete mortar, as well as to individually determine the temperature of the exhaust gas and the amount of steam. There is provided a curing system that can be controlled. The supply of high-temperature exhaust gases enables the curing system to operate on the ground even in winter, greatly reducing the cost of the facility.

In addition, since waste heat of the exhaust gas generated by incineration of the waste is used for curing as it is and steam is generated from the exhaust gas, it is not only environmentally friendly but also high energy efficiency can be obtained. Furthermore, the energy efficiency is further maximized by supplying the heat from the incineration of the waste to the water provided as steam.
