Description

Welded plate heat exchanger

Technical Field

The utility model relates to the technical field of heat exchange, in particular to a welded plate type heat exchanger.

Background

Heat exchange is the process of heat transfer between two objects or parts of the same object due to temperature differences. Heat exchange is generally accomplished by three means, heat conduction, heat convection, and heat radiation. A thermal energy exchanger is a device that transfers heat from one fluid to another. The method is divided into a mixed type and a surface type. The heat transfer process in a hybrid heat exchanger is by direct mixing of hot and cold fluids. The hybrid condenser is one of hybrid heat exchange devices. Heat is transferred from one fluid to another through the solid walls in surface heat exchange devices. The steam heater, evaporator, heating power network water heater and surface condenser of steam turbine used in thermal power plant are all surface heat exchanger.

However, the existing heat exchanger often has the problems that the environmental protection effect is not good, the heat exchange flue gas is not effectively filtered, the emission does not meet the requirements of energy conservation and emission reduction, and the effective utilization of resources is not facilitated.

Preferably, an air exhaust device is arranged on the right side of the heat exchange main body and comprises a fan and an air outlet pipe, and the fan is arranged on the air outlet pipe.

Preferably, the left side of air-out pipe is connected with the heat transfer bulk phase, the right side of air-out pipe is connected to in the water tank, the upper portion of water tank is provided with the chimney.

Preferably, a clamping piece is arranged on the spring and is arranged on one side close to the filter screen.

Preferably, the lower end of the heat exchange main body is provided with an ash collecting device, and the ash collecting device comprises an ash collecting hopper and a dust discharging port.

Preferably, a valve is arranged on the dust exhaust port, and vibrators are fixedly arranged on two sides of the outer wall of the dust collecting hopper.

Compared with the prior art, the utility model has the following advantages:

1. the filter screen device is arranged on the air inlet, the filter screen is more convenient to disassemble, replace and clean through the combined structure of the U-shaped clamping plate, the clamping piece and the filter screen, and the spring is arranged on the filter device, so that the buffer effect can be increased;

2. the heat exchanger not only efficiently recycles the heat exchange effect of waste gas, but also thoroughly removes dust and impurities by connecting the air outlet pipe into the water tank, so that the gas discharged from the chimney is more environment-friendly;

3. the dust collecting hopper is provided with the vibrators on two sides, and dust accumulated on the inclined plate of the dust collecting hopper bin wall can be shaken off to the dust discharging port through the vibrators, so that the dust can be discharged.

To sum up, this kind of welding formula plate heat exchanger has extensive practicality to solve the current heat exchanger that mentions among the above-mentioned background art and often have the environmental protection effect not good, do not carry out effectual filtration to the flue gas of heat transfer, the emission is not conform to energy saving and emission reduction's requirement, is unfavorable for the problem of the effective utilization of resource, has higher spreading value.
