Abstract

The utility model discloses a novel structure of a circulating water cold and hot water pool. The novel structure of the circulating water cold and hot water pool is composed of a cold water pool, a hot water pool, and a pump room. A partition wall is provided between the cold water pool and the hot water pool. A flow guiding hole is arranged on the partition wall. The cold water pool is connected with a water replenishing pipe, and the hot water pool is connected with an overflow pipe. The utility model has the advantages that the novel structure of the circulating water cold and hot water pool has a simple structure, engineering cost can be saved, the running of a system is balanced, energy consumption is lowered, etc. The novel structure of the circulating water cold and hot water pool can be extensively used in industry and civil circulating cooling water systems.

Description

Recirculated water cooling hot-tub new construction

Technical field:

The utility model relates to the hot and cold pond of a kind of recirculated cooling water new construction.

Technical background:

Industrial, civilian recirculating cooling water system is under the gravity water return condition, the General System configuration is that circulating backwater is back to hot-tub, be promoted to the cooling tower cooling through heat-exchanger pump, supply with the user through water supply pump to water cooling pond again, recirculated water produces loss in cyclic process, new water is supplemented to water cooling pond with the form of supplementing water, and keeps a certain amount of overblow blowdown, keeps system water mass balancing and auxiliary water stabilization.There are the following problems in this system: 1) hot and cold pond must be provided with overflow pipe respectively with equalizing reservoir water level and prevent to emit groove, has increased overflow pipe and supporting pipe network expense; 2) owing to hot-tub changes because of loss in adjustment of cooling water user water consumption and the system, make the hot-tub water-level fluctuation, hot water or cold water's pump operation balance condition point be in dynamic change, need experienced operating personnel constantly to adjust water supply valve according to user situation, to avoid the pond to blot, increased the difficulty that balance movement is adjusted; 3) owing to, adopt the measure of quantitative blowdown usually, discharge and make new water supplementing water pass through the water cooling pond overflow pipe, with respect to more wasting the water at low temperature resource in the hot-tub blowdown for keeping the stable of circulating water quality.

Summary of the invention:

The purpose of this utility model is: a kind of structural form of convincing discharge orifice between the recirculated water cooling hot-tub by patient analysis is provided, not only can reduce engineering cost, make system's operation balance more easy to control, and can effectively adjust the seasonal intermitten service problem of heat-exchanger pump, cooling tower under certain condition.

The utility model is to constitute like this: it is by water cooling pond (1), hot-tub (2), and pump house (3) is formed, and is provided with partition wall (4) between water cooling pond (1) and the hot-tub (2), has pod apertures (5) on partition wall (4); Water cooling pond (1) connects filling pipe (6), and hot-tub (2) connects overflow pipe (7).

The utility model compared with prior art has simple in structurely, can save engineering cost, and system's operation balance has reduced advantages such as energy resource consumption.

After adopting such improvement, the hot and cold pond of system imposes a condition down to form and is communicated with, and only keeps overflow pipe of hot-tub.The continuously new water moisturizing of system at first enters water cooling pond, and the water cooling pond water level is kept constant at water conservancy diversion intercommunicating pore absolute altitude; Water yield overflow more than needed is to the loss of timely replenishment cycles water use of hot-tub and backwater process, and hot-tub is owing to system's continuous blowdown requirement, and overflow pipe carries out continuous blowdown, and the hot-tub water level forms constant.Water cooling pond is in time constant to the system water pool water level of hot-tub moisturizing and formation, efficiently solve that hot and cold water pump operating point does not match and problem such as user's water consumption adjustment, avoided the pond to blot and the problem that keeps hot and cold water pump operating point to adjust the water pump water outlet valve synchronously and constantly occurs.System only keeps overflow pipe of hot-tub, has reduced water cooling pond overflow pipe and supporting pipe-networks engineering expense relatively.Can be higher than under the pod apertures absolute altitude specified conditions at hot-tub overflow pipe absolute altitude, the hot and cold pond that forms by pod apertures is communicated with, can realize that hot water refluxes to water cooling pond, Various Seasonal is reasonably combined between realization heat-exchanger pump and cooling tower, reduces system's hot water cooling operating cost.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the schematic diagram of the utility model under the feasible specific site condition of place elevation layout.

The specific embodiment:

Embodiment of the present utility model:

Figure 1 shows that basic embodiment of the present utility model.Partition wall (4) is set between hot and cold pond (1), (2), establishes pump house (3) below; Have pod apertures (5) on the partition wall (4), thereby cancelled water cooling pond overflow pipe in the legacy system, this part is configured to hot-tub overflow position H3 and is lower than water cooling pond water level control position (H1+H2), i.e. H3＞H1+H2.Water cooling pond (1) connects filling pipe (6), and hot-tub (2) connects overflow pipe (7).The size dimension of pod apertures (5) is specifically calculated by common waterpower by the designer according to system's design to be determined; Pod apertures (5) end, is provided with absolute altitude (being water cooling pond control water level elevation) the pond superelevation H2 (generally adopting 0.2m) that design is adopted according to system and calculates the high H1 of pod apertures and specifically determined by the designer; Pod apertures (5) plan-position is by general conventional definite.

Figure 2 shows that the utility model is had ready conditions is configured to hot-tub (2) overflow position H3 and is higher than water cooling pond (1) water level control position (H1+H2), promptly under the condition of H3≤H1+H2, and the mode of pod apertures (5) configuration.Absolute altitude (H1+H2), plan-position is definite identical with Fig. 1 at the bottom of the size dimension of its pod apertures (5), the hole.

Claims
