Steam generator with balanced pressure

Abstract

The invention provides a steam generator with balanced pressure. According to the steam generator, a first electric heater, a second electric heater and a third electric heater are respectively arranged in a left tube box, a middle tube box and a right tube box, a uniformizing pipe communicating with the left pipe box and the right pipe box is arranged between the left pipe box and the right pipe box, the uniformizing pipe is arranged at the position above the middle of the left pipe box and the middle of the right pipe box, a valve is arranged on the uniformizing pipe, the left pipe box and the right pipe box are respectively provided with a pressure sensor, the pressure sensors and the valve are in data connection with a controller, and the controller controls opening and closing of the pressure valve according to the pressure difference between the left tube box and the right tube box. According to the steam generator of the novel heat pipe structure, pressure balance of the left pipe box and the right pipe box is automatically regulated and controlled, so that it is guaranteed that heat exchange on the left side and the right side is uniform, and balance control over the system is achieved.

Description

technical field [0001] The invention relates to steam generating equipment, in particular to a steam generator for intermittent vibration descaling. Background technique [0002] The steam generator is used to generate steam, which is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into steam. The steam generator has a wide range of applications, and is widely used in garment factories, dry cleaners, restaurants, steamed bun shops, canteens, restaurants, factories and mines, bean products factories and other places. In the applicant's previous application, a new type of coiled electric heating coil was developed and researched, such as CN106123306A, so that the elastic tube bundle caused by the expansion of the fluid caused by heating causes vibration, thereby achieving heating and descaling Effect. [0003] However, in the application, it is found that the continuous heating of the electric heater will lead to the stability of t...

Problems solved by technology

[0007] However, because the left tube box and the right tube box are independent structures, the pressure on the left and right sides is unbalanced or the liquid level is unbalanced, which leads to uneven heat transfer on the left and right sides, resulting in high local temperature and even high pressure.
