Description

Steam generator using vacuum pump {omitted}

The present invention relates to a steam generator using a vacuum pump, and more particularly, by using a vacuum pump to evaporate water at a low temperature to increase the pressure again to create a high temperature steam to produce hot water or high temperature steam pump It relates to a steam generator using.

Although there are various types of boilers, they are generally divided into hot water boilers producing hot water and steam boilers requiring high temperature and high pressure.

In particular, the steam boiler burns fossil fuel by using a burner to transfer the calorific value of the fuel to water so that the water pressure becomes high temperature and high pressure, and supplies steam generated from the steam boiler to produce hot water, heat or heat using a heat exchanger. I use it.

Since the conventional steam boiler heats the water directly by using a burner to increase the pressure, a high temperature is required until the steam becomes steam, and thus the exhaust gas temperature of the boiler is increased due to the high temperature, which consumes a lot of fuel costs, resulting in high energy consumption. It has a high temperature of water, so if it explodes, there is a problem that leads to a large accident. In addition, since the conventional steam boiler uses high temperature and high pressure, a basic education is required due to a complicated safety device, resulting in a complicated facility and a large cost due to such a safety device.

The present invention has been made to solve the above problems, an object of the present invention, by lowering the pressure of the water so that the water can be evaporated at a low temperature, by pressurizing the evaporated steam to provide a high temperature steam The aim is to provide technology that eliminates the risk of explosion, reduces installation costs, saves energy and eliminates dangerous steam boilers.

According to the present invention for solving the above problems, a steam generator using a vacuum pump is a vacuum pump for lowering the pressure so that water can be evaporated at a low temperature; A radiator (heat exchanger) installed at the outlet of the vacuum pump and dissipating hot steam latent heat; A tank for storing liquid at an outlet of the radiator; A pressure equalizing tube connected to the radiator inlet at the top of the tank; A pressure regulating valve for regulating pressure at the outlet of the tank; A heater (heat exchanger or electric heater) supplied with an external heat source by regulating (lowering) the pressure in the pressure regulating valve; Characterized in that

Steam generator using a vacuum pump according to the present invention having the characteristics as described above, since the water is evaporated at a low temperature, and the evaporated steam to make a high temperature steam by using a vacuum pump, there is no risk of explosion, exhaust Since there is little heat loss due to gas and insulation, energy saving and installation cost are low, and high pressure steam boiler is eliminated.

1 is a representative view showing a steam generator using a vacuum pump according to the present invention.

The steam generator using the vacuum pump is a vacuum pump for lowering the pressure so that water can be evaporated at a low temperature (10); A radiator 20 (heat exchanger) installed at an outlet of the vacuum pump 10 to discharge latent heat of steam at high temperature and high pressure; A tank (30) for storing a liquid (condensed water) connected to a conduit (22) at the outlet of the radiator (20); A pressure equalizer tube 31 connected to the steam at the upper portion of the tank 30 so as to be moved to the inlet of the radiator 20 again; A pressure regulating valve 40 for regulating pressure connected to the tank 30 and the conduit 32; And a heater 50 connected to the pressure control valve 40 and the conduit 41 and supplied with an external heat source 51 (electric heater or heat exchanger).

A representative figure shows a steam generator using a vacuum pump according to the present invention.

The vacuum pump 10 strongly sucks the steam of the heater 50 connected to the conduit 52 to lower the internal pressure of the heater 50 so that water can be evaporated, and the vaporized steam is again the vacuum pump ( 10 is compressed to produce a high-temperature steam is supplied to the radiator 20 or a steam distributor (not shown) connected to the conduit (11). The radiator 20 supplies heat to a heat exchanger for dissipating heat 21, thereby dissipating heat 21, and dissipates heat 21 so that hot steam is condensed (water) and connected to the conduit 22. It is introduced into the tank 30 for storing water.

Preferably, the tank 30 is installed at a lower position than the radiator 20 so that water can be naturally stored, and steam from the upper part of the tank 30 is equalized to the equalizing tube 32 to the radiator 20. Connect to the inlet to allow water to circulate smoothly.

The tank 30 for storing the condensed water is supplied to the pressure control valve 40 for adjusting the pressure connected to the conduit 32 to lower the pressure and to the heater 50 connected to the conduit 41 to provide external heat. Received 51 is supplied to the vacuum pump 10 connected to the conduit 52 again.

Preferably, the stronger the suction force of the vacuum pump 10, the greater the degree of vacuum inside the heater 50, so that water is evaporated at a lower temperature, so even if the temperature of the heat 51 supplied from the outside is low, I can make it.

Steam generator using a vacuum pump according to the present invention as described above can supply the low temperature heat 51 to the heater 50 can produce a high temperature steam in the radiator 20 can effectively absorb the waste heat, It is effective in eliminating energy waste due to condensate generated in conventional boilers, and operates at low pressure and low temperature, reducing energy waste due to insulation, and eliminating the risk of explosion because it does not store hot water. have.
