Abstract
The utility model discloses a circulating water cooling tower comprising a tower body and a water inlet pipe, wherein a pool is arranged on the bottom of the tower body, one end of a backwater side pipe is communicated with the water inlet pipe, the other end of the backwater side pipe is communicated with the pool, and a valve is installed on the backwater side pipe. According to the circulating water cooling tower, the backwater side pipe is connected on the water inlet pipe, the valve on the backwater side pipe is opened to directly guide part of backwater to the pool on the bottom of the water cooling tower without being cooled by the water cooling tower when the temperature of the backwater of the circulating water is low in winter, and the flow rate is adjusted via the valve to control the temperature of the backwater so as to prevent severe freezing phenomenon in the tower.
Description
Technical field
The utility model belongs to chemical industry equipment, relates in particular to a kind of circulating water cooling tower.
Background technology
In the benzene hydrogenation device, the circulating water cooling tower is a kind of structures of cold water, using water wisely, cycling use of water.Its operation principle is: utilize the wind blow into and by on spill the water that gets off and form convection current thermal source is drained, a part of water evaporates in convection current, has taken away corresponding evaporation latent heat, thus the temperature of reduction recirculated water.Because the geographical position of living in four seasons temperature difference is large, the summer climate temperature reach as high as 40 the degree more than, winter minimum temperature to subzero 10 the degree below, season the temperature difference reach 50 the degree more than.The winter of every cold, because the recirculated water return water temperature is lower, more serious through the cooling icing phenomenon of recirculated water that causes of cooling tower, be covered with a large amount of ice slushes inside cooling tower, continue approximately whole winter, the robustness of cooling tower is brought great threat.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of circulating water cooling tower is provided, and solves the problem that winter, recirculated water froze in cooling tower.
For achieving the above object, the utility model adopts following technical scheme: a kind of circulating water cooling tower comprises tower body and water inlet pipe, the pond is arranged at the tower body bottom, have an end of the other pipe of a backwater to communicate with water inlet pipe, the other end communicates with the pond, on the other pipe of backwater, valve is housed.
Valve on the other pipe of backwater is choke valve.
Adopt the circulating water cooling tower of technique scheme, be connected to the other pipe of backwater on water inlet pipe, when the recirculated water return water temperature is low in the winter time, open the valve on the other pipe of backwater, to pond, cooling tower bottom, and cooling without cooling tower is by the valve regulated flow the direct drainage of part backwater, control return water temperature, can prevent from freezing in tower serious.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Circulating water cooling tower as shown in Figure 1 comprises tower body 1 and water inlet pipe 3, and pond 2 is arranged at tower body bottom, has an end of the other pipe 4 of a backwater to communicate with water inlet pipe 3, and the other end communicates with the pond, and the backwater side is managed on 4 valve 5 is housed.
Valve on the other pipe of backwater is choke valve.
When summer, the recirculated water return water temperature was high, the other pipe of backwater is closed, make whole recirculated water backwater cooling via cooling tower; When the recirculated water return water temperature is low in the winter time, open the valve on the other pipe of backwater, to pond, cooling tower bottom, and cooling without cooling tower by the valve regulated flow, controlled return water temperature, can prevent from freezing in tower serious the direct drainage of part backwater.
The increase of the other pipe of cooling tower backwater makes the recirculated water return water temperature control elasticity larger, has also guaranteed the safe and effective operation of cooling tower simultaneously, for the normal production of benzene hydrogenation device escorts.
Claims (2)
1. a circulating water cooling tower, comprise tower body and water inlet pipe, and the pond is arranged at tower body bottom, it is characterized in that: have an end of the other pipe of a backwater to communicate with water inlet pipe, the other end communicates with the pond, on pipe, valve is housed by backwater.
2. circulating water cooling tower as claimed in claim 1 is characterized in that: the valve on the other pipe of backwater is choke valve.
