Abstract
The invention provides an acid evaporator heating system which adopts a high-temperature furnace gas as a heat source and comprises a cold-hot heat exchanger, a moderate temperature coal economizer, a low-temperature acid evaporator and a high-temperature acid evaporator. The acid evaporator heating system is divided into two routes, wherein one is a low-temperature heat supply route, the high-temperature furnace gas passes through the cold-hot heat exchanger and flows into the moderate temperature economizer connected with the cold-hot heat exchanger by virtue of a pipeline, and the heated furnace gas treated by the moderate temperature economizer is directly supplied to the low-temperature acid evaporator so as to be heated; and the other one is a high-temperature heat supply route, the high-temperature furnace gas is directly supplied to the high-temperature acid evaporator by virtue of a line (1) and a line (2) so as to be heated, the heated gas is supplied to the low-temperature acid evaporator by virtue of a line (3) so as to be heated, and a ball valve is arranged on the line (1). The acid evaporator heating system provided by the invention is simple in structure, and is capable of heating the high-temperature acid evaporator by using the high-temperature furnace gas and heating the low-temperature acid evaporator by using the used furnace gas by virtue of the high-temperature heat supply route, thereby conserving the energy.
Description
Technical field
The present invention relates to gas washing in SA production field, specifically refer to the sour device heating system of a kind of steaming.
Background technology
High temperature steams sour device and uses high-temperature furnace gas as heating source, used gas is directly used for heating low temperature and steams sour device heat not, if use steam dangerous as heating source technics comparing, an amount heating steam pipe leaks, water vapor and oleum meeting vigorous reaction, consequence is unimaginable.
Summary of the invention
For solving the problem, the invention provides the sour device heating system of a kind of steaming.
Concrete solution is: the sour device heating system of a kind of steaming, comprise hot and cold heat exchanger, middle temperature economizer, low temperature steams sour device and high temperature steams sour device, system is divided into two circuits, article one, be low-temperature heat supply circuit, high-temperature furnace gas is warm economizer in hot and cold heat exchanger is connected with hot and cold heat exchanger by pipeline flow-direction, through in heating furnace gas after warm economizer process directly supply low temperature and steam the heating of sour device; Another is high-temperature heat supply circuit, 2. 1. high-temperature furnace gas directly supply high temperature with circuit by circuit and steam the heating of sour device, 3. gas after heating supply low temperature by circuit and steam the heating of sour device, described circuit 1. on be provided with ball valve, when low temperature steam sour device steam acid amount less time, can ball valve be closed, only use low-temperature heat supply circuit to heat it.
Further, described ball valve is Stainless Steel Valve.
Structure of the present invention is simple, and the setting of high temperature supply lines not only can use high-temperature furnace gas to steam sour device to high temperature to heat, and the furnace gas after using can also be used to steam sour device to low temperature and heats, save energy.
