High-pressure high-temperature hot-water supply device

Abstract

The invention relates to a high-pressure high-temperature hot-water supply device comprising a preheating tank, a combustion chamber, a combustor, a heating coil, an exhaust pipe, an exhaust fan, a high-pressure pump and an electric controller. A cool-water inlet and a warm-water outlet are arranged in the preheating water tank, a warm-water inlet and a high-pressure high-temperature hot-water outlet are arranged in the heating coil, the warm-water outlet in the preheating water tank is connected with the high-pressure pump through a pipeline, a pipeline arranged on the water outlet of the high-pressure pump is connected with the warm-water inlet in the heating coil, the combustion chamber is of a semi-closed chamber, and the heating coil and the combustor are jointly arranged in the combustion chamber in a top-and-bottom corresponding manner; the exhaust pipe is entirely embedded in the preheating water tank, one end of the exhaust pipe is led in through the bottom of the preheating water tank while the other end is led out through the side wall of the preheating water tank, and the exhaust fan is arranged at the leading-out end of the exhaust pipe; a water return opening is arranged in the preheating water tank and is communicated with a pressure relief opening arranged at the position of the high-pressure high-temperature hot-water outlet through a water return pipe, and a pressure relief valve is arranged on the water return pipeline. The high-pressure high-temperature hot-water supply device is high in heat utilization, short in heating time and good in safety performance.

Description

technical field [0001] The invention belongs to the field of hot water supply equipment, in particular to a high-pressure and high-temperature hot water supply device. Background technique [0002] At present, for cleaning carpets, sofas, curtains and floors, the traditional cleaning method is to use a bristle brush to scrub the object to be cleaned, which will damage the object to be cleaned, and the cleaning speed is slow, and the drying speed after cleaning is also slow. In addition, sometimes in order to complete the cleaning, the cleaning object must be disassembled in advance, so that it is very troublesome to assemble after cleaning and drying. Currently, steam is used for washing and drying, and electric heating is used, but in reality, due to excessive power supply restrictions, the operating voltage is 220 volts, and the temperature is low and the pressure is low, which cannot effectively sterilize and remove mites on the cleaned objects. But also there is cleanin...

AI Technical Summary

Problems solved by technology

The high-pressure hot water supply part includes the preheating water tank, high-pressure pump, gas heating and heat exchange device, smoke exhaust device, etc., but the structure has the following shortcomings during use: 1. The heating and exchange device is not compatible with the preheating The bottom of the water tank is in contact, the preheating water tank is heated on one side, and the combustion chamber where the heating and exchange device is located is open, so the heat utilization rate is low, and the heating time is longer under the premise that the hot water supplied meets the same temperature; 2. Partial exhaust The smoke pipe passes through the preheating water tank, and the use of the hot gas and waste heat lost through the smoke exhaust pipe is limited, and even the gas discharged from the smoke exhaust pipe may be hot and easily burns, so there is a safety hazard; 3. At the same time, there is a lack of return water and Circulation heating structure, water heating time is relatively long
